Oedipus The King Intrusion

Oedipus The King Intrusion
Intrusion is defined as "a pushing, thrusting, or forcing in." Every play in existence has an intrusion
in it. Intrusions are what help the play along and can start conflict or end it. Oedipus for example has
tons of intrusions! One of the first one's being Oedipus himself! At the beginning of the play all the
Chorus is at the foot of the palace, near the memorial for Apollo. They are all seated there, but the
scene does not tell the audience why at first. Oedipus intrudes by coming out of the palace and says
"My children, new–sprung race of old Cadmus, why do you sit at my shrines?" Then the Priest
stands up and approaches Oedipus, and explains to him why the Chorus is all there. This sparks the
conflict of the plague, Chorus sits by the Apollo shrine, Oedipus asks why, and he is told it is
because they all want a cure or a sign of how to cure the plague torturing Cadmus. It is the first and
one of the most important intrusions in the play. The most perfectly written tragedy of all time is
Oedipus Rex according to Aristotle and his six requirements. Those six requirements are as
followed: Story, Characters, Theme/Thought, Spectacle, Music, and Dialogue. Oedipus Rex has a
compelling story, a plot! It is interesting, it brings the audience and reader in. The plot being in basic
terms: A plague has fallen upon Cadmus, when Creon returns with a prophecy Oedipus is
determined to find out the truth of the message and put an end to the plague. Within that all the

Virtual Machine Intrusions
The technique can detect DDoS attacks as well and blocking complete botnets (Amna Riaz 2017).
However, NIDS is going to face issues processing all packets in large virtual network and it may fail
to detect attacks in time as SNORT is single threaded.
Another solution that has been studied is Virtual Machine Introspection (VMI) based technique
(Amna Riaz 2017). Virtual machine introspection (VMI) is the main idea behind out–of–box
intrusion detection. VMI is a technique of inspecting VM state by moving the inspection module
outside of the VM. The software running inside the guest system is analysed externally to detect any
intrusion. One advantage of this technique is that malware detection continues to work unaffectedly
even in the ... Show more content on Helpwriting.net ...
However, on the brighter side a NIDS has high attack resistance ().
Being SNORT as a single threaded, processing huge logs for the cloud computing is an issue so
multi thread IDS is essential in the cloud computing (Parag K. Shelke 2012, p. 68). SURICATA is
multi–threaded and could resolve the performance issues and packet loss we face with the single
thread IDS.
Virtualization has made network management more challenging, and it's more and more difficult to
consistently apply firewall and content filtering policies. When you add in complexities such as
securing BYOD devices, the security problem is intensified. Software–defined networking (SDN) is
next evolving technology for the cloud computing. SDN is an umbrella term covering several kinds
of network technology aimed at making the network as agile and flexible as the virtualized server
and storage infrastructure of the modern data center. The SDN Controller provides a centralized
system to manage the network. The network administrators are empowered by SDN to easily access
and manage individual flows by facilitating them to implement monitoring applications, i.e., firewall
and IDS. Furthermore, scalable monitoring and dynamic reconfiguration requirements of the
network in cloud makes SDN a perfect choice (Amna Riaz 2017).
Using OSSEC and BRO as IDS tools can also help to resolve analysing and integrating the log files
as OSSEC has a powerful

Taking a Look at Intrusion Detection
Intrusion Detection Intrusion detection is similar in concept to a burglar alarm on a car. There is the
lock system to prevent access to a car, similar to a firewall, and there is the alarm system, the
intrusion detection system. Intrusion Detection Systems (IDS) are there to compliment the network
or computers firewall, if or when there is a breach, it is the IDS that is able to identify it and then
alert the administrator. Firewalls are an effective way for filtering information coming in to your
network from the internet and are a good source of protection, but there are ways to circumvent a
firewall which could leave you defenseless. An IDS monitors the firewall for breaches and also
monitors the traffic on the organizations network for any anomalies. This is important in the instance
of an external user connecting to an organizations infrastructure by connecting through an installed
modem on the network, this form of attack cannot be caught by a firewall but an IDS is able to
recognize the abnormal activity and report the intrusion to an administrator. Intrusion detection
systems are there to help an information system prepare for and deal with attacks. They collect
information from a variety of system and network sources and then analyze the information and
activity logs searching for information on potential security problems. Some of the main tasks of an
IDS are to monitor and analyze the user and system activity on a network, to audit the systems

Options For Implementing Intrusion Detection Systems Essay
Options for Implementing Intrusion Detection Systems Signature based IDS These IDS possess an
attacked description that can be matched to sensed attack manifestations. It catches the intrusions in
terms of the characteristics of known attacks or system vulnerabilities. This IDS analyzes
information it gathers and compares it to a database of known attacks, which are identified by their
individual signatures. The rules are pre–defined. It is also known as misuse detection. The
drawbacks of this IDS is that they are unable to detect novel or unknown attacks, Suffer from false
alarm and have to programmed again for every new pattern to be detected. Anomaly based IDS This
IDS models define the baseline to describe normal state of network or host. Any activity outside
baseline is considered to be an attack i.e. it detects any action that significantly deviates from the
normal behavior. The primary strength is its ability to recognize novel attacks. The drawback is that
it assumes that intrusions will be accompanied by manifestations that are sufficiently unusual so as
to permit detection. These generate many false alarms as well and hence compromise the
effectiveness of the IDS. Network based IDS This IDS looks for attack signatures in network traffic
via a promiscuous interface. It analyzes all passing traffic. A filter is usually applied to determine
which traffic will be discarded or passed on to an attack recognition module. This helps to filter out
known un–malicious

Cyber Attacks, Intrusion Attacks And Network Attacks
Introduction Organizational entities which store sensitive data and information have the
responsibility of ensuring that the data are secure. Ensuring that this particular data and information
are secure will more than likely be the responsibility of the Information Technology Security
Executive. These executives will be required to implement the protocol and, software that will deter
and prevent the different types of attacks that their organization faces. Some of the attacks include
cyber– attacks, intrusion attacks, network attacks, and social engineering attacks. This paper will
present research and comparison of methods of cyber–attacks, intrusion attacks and network attacks.
Comparison of Cyber–Attacks, Intrusion Attacks, and Network Attacks Cyberterrorism, cyber
campaigns, and cyber–warfare are all considered forms of cyber–attacks. Therefore, the spectrum of
cyber–attacks will employ the gamut from computer viruses to data hacking targeting individual
computers to organizations infrastructures and networks. These attacks have become more
sophisticated and dangerous. McLaughlin (2011) Portends that international concern has intensified
due to recent cyber–attacks. McLaughlin (2011), Stated that governments that known for being
hostile could launch computer–based attacks on critical systems which are national and regional
(McLaughlin, 2011). These systems include energy distribution, telecommunications, and financial
services (McLaughlin, 2011).

ABSTRACT
There are various issues in intrusion detection system. It must detect the malicious activities going
on in a network and deal with the enormous amount of network traffic. In this paper,things like
accuracy and efficiency using CRFs and Layered Approach have been addressed.
The CRFs reduce the number of false alarms thus improving the attack detection accuracy,while the
overall system efficiency can be improved using Layered Approach.Thus, an obvious way it to sum
them up for building a system that accurately detects attacks.Four attack layers are selected related
to the attack groups(U2R, DoS, R2L, and Probe) and perform feature selection for each layer. The
results from individual classifiers at a layer are not combined at any later stage in the Layered
Approach, hence,we can block the attack at the detected layer.

An Analysis of Seawater Intrusion in Coastal Aquifers
Seawater intrusion is defined as the movement of seawater into freshwater aquifers which are
generally made of ground water near the coast. An interface or dispersion zone is the area where
fresh water and seawater meet. Analytical models and numerical models as well as Mathematical
methods are used to find or to investigate solutions to this, as the seawater contaminates the fresh
drinking water. The aim of this essay is to give an account of two modelling approaches that
describe what happens at the interface by discussing the models. As well as to discuss how tides
may have an impact on seawater intrusion. Ataie–Ashtiani, Volker and Lockington(1999:17)
suggested that there is a direct relationship between the area of the dispersion, the scale, the shape,
the degree of the dispersion area, and parameters such as hydraulic conductivity, the comparative
densities of the salt and fresh water as well as the rate of discharge of the ground water. There is
limited accuracy to the usage of the models as the models are limited by assuming various
situations. Altaie–Ashtiani et al (1999:18) gestates the rare occurrence of salt–water intrusion in
ground water in two ways: the sharp–interface approach and the disperse interface approach. The
sharp–interface approach is the approach in which it should be assumed that the salt water and fresh
water are immiscible fluids which are separated by a sharp interface. This approach includes the
diffusion and the effects of the hydrodynamic

Abstract:– public cloud is vulnerable to threats from attackers. in this paper we propose a method to
protect the data in cloud computing using intrusion detection and prevention system. It helps to
protect the data from unauthorized access and from various attacks to the cloud environment .we
propose a method where IDS with HONEYPOT can be integrated at the provider side to have a
robust data security for the cloud user data access. 1.Introduction:– In this century, Internet is on the
edge of another revolution, where resources are globally networked and can be easily shared. Cloud
computing is in the focus that uses the Internet as a large repository where resources are available to
everyone as services.[5]. many people prefer cloud services for its flexibility,versatility,anywhere
accessibility of the services through internet. Cloud Computing is an internet based computing
technology primarily based on utilization of computing power that provides different types of
services by utilizing pool of resources mainly hardware, software, database, network, in terms of
pay–for–use basis as per specific Service label agreement. Cloud Computing is becoming more and
more popular at present information technology setup of many large organizations. [2]. security
plays a major role from the user prospective in the cloud environment. Cloud computing also suffers

The Tort Of Intrusion On Seclusion
Introduction
The Ontario Court of Appeal recognized the tort of intrusion on seclusion in Jones v Tsige. This
decision provided the foundation for determining damages under the tort. The foundation in Jones
was modified by case law. This multiple case analysis will explore how an Ontario court should
calculate damages, with reference to the following cases: Alberta v Alberta Union of Provincial
Employees, Hopkins v Kay, and Condon v Canada. Taken together, these cases indicate that a
damage award in Ontario should reflect the offensiveness of the invasion of privacy and the harm it
caused. These factors should be balanced against any steps taken by the defendant to rectify the
breach. Ultimately, this assessment should be ... Show more content on Helpwriting.net ...
The interest protected by the tort is intangible. Therefore, proof that a recognized economic interest
was harmed is not required. For this reason, Sharpe JA capped potential damages at $20,000. Sharpe
JA is trying to leave room to differentiate between degrees of highly offensive intrusions. He
concluded that a range is necessary to maintain "consistency, predictability, and fairness between
one plaintiff and another".
To determine where a case fits within the range, an Ontario court should consider five factors when
assessing damages:
(1) The nature, incidence and occasion of the defendant's wrongful act, (2) the effect of the wrong
on the plaintiff's health, welfare, social, business or financial position, (3) any relationship, whether
domestic or otherwise, between the parties, (4) any distress, annoyance or embarrassment suffered
by the plaintiff arising from the wrong, and (5) the conduct of the parties, both before and after the
wrong, including any apology or offer of amends made by the defendant.
Sharpe JA did not mention whether this list was exhaustive. Furthermore, aggravated and punitive
damages are neither excluded nor encouraged under the tort, unless the case is exceptional.
Sharpe JA found that the defendant's deliberate and repeated actions arising from a complex
domestic arrangement, and its provocation of strong feelings and animosity in the plaintiff, favoured
a higher award. In contrast, the fact that the plaintiff suffered no

I. Introduction:
The Internet is a global public network and it is the Universal source of information. It has become a
popular medium for commercial activities. Millions of dollars of transactions occur daily in many
financial organizations through Internet. The internet along with digital technologies has taken
human life into much higher levels of sophistication and ease. The growth of Internet has brought
about great benefits to the modern society; meanwhile, the rapidly increasing connectivity and
accessibility to the Internet has posed a security threat. With the tremendous growth of network–
based services and sensitive information on networks, network security is getting more and more
import than ever. The attacks on the Internet have become both more prolific and easier to
implement because of the ubiquity of the Internet and the pervasiveness of easy–to–use operating
systems and development environments.
Data is often the most valuable asset possessed by an organization and it is the main target of
intentional attacks. Data stored, processed, and transmitted by a computer system must be protected.
Business organizations use the internet as an important aspect of their business model. In addition to
using internet applications, such as the web and email, to generate revenue and communicate with
customers, they also store important and proprietary information on computers that are accessible

A New Comprehensive Hybrid Model For Improving Intrusion...
IV. PROBLEM IDENTIFICATION AND DEFINITION The purpose of this task is to create a new
comprehensive hybrid model for improving Intrusion Detection and Prevention System in Cloud
Computing. The problem in [11] authors was not focused on providing experiments to prove the
effectiveness of implementation of collaborative filtering algorithm constructed on the cloud model
onto illegal access detection problem in the cloud computing environment. In this paper [15] authors
did not Implemented IDS architecture but used an apriori algorithm to detect frequent attacks. The
future research will be including a feedback mechanism such that the frequent attacks detected by
the IDS were updated to the signature database. This would ensure that it weren't remaining as an
unknown intrusion in future. These limitations of traditional intrusion detection systems, there are
some other problems which are faced by many of the intrusions systems. They are: 1) Fidelity
problem: During the examination of attacks, IDS make use of the data related to network packets
which is stored in log files. During the transmission of data from source (log files) to the place
where IDS is positioned, data may be modified by the intruder. This may result in missing of some
of the events. This refers to fidelity problem. 2) Resource usage problem: Most of the intrusion
detection systems are designed in such a manner that all of its components work all the time even
though when there is no sign of intrusions found

information systems have become an integral part of every day life. In fact, there are not too many
public or private actions that can take part in today's society that do not include some type of
information system at some level or another. While information systems make our lives easier in
most respects, our dependency upon them has become increasingly capitalized upon by persons with
malicious intent. Therefore, security within the information systems realm has introduced a number

HIDS are also somewhat cost–effective in comparison to other IDS types since they are most
commonly software–based on not a hardware appliance. Unfortunately, there are a number of
disadvantages to HIDS, as well. The most significant problem with HIDS is that the majority are
software–based and operate on the system itself. What this can lead to is controlling the HIDS if the
system becomes entirely compromised. HIDS can also be difficult to manage if spread across many
systems without an efficient administration plan in place. Finally, HIDS use the same resources the
server it resides on uses. Depending on the activity of the server, a HIDS can be quite a burden to an
already busy system. This can lead to bottlenecks, costly hardware upgrades, and other technical
issues (Shimonski, 2004, para. 6). Network–based IDS Network–based IDS, or NIDS, are normally
hardware–based devices (or dedicated systems) that reside at critical points of the network –
capturing all incoming (and sometime outgoing and localized) packet traffic and analyzing it for
suspicious patterns in accordance with the signature or rule database. Specifically, NIDS capture IP

Proposed work we have used OSPF routing protocol that is distance vector protocol that has
following characteristics. 1) Only gets updates once changes square measure wiped out topology 2)
Only updates changes in routing table , doesn't replace entire routing table 3) Packet blocking or
node block system supports 4) Can decide the packet size and path manually 5) Much quicker than
AODV. We have followed many steps for implementing IDS and block system: 1. PDR (Packet
Delivery Ratio) – It 's the amount of delivered information packets to the node The bigger is that the
price of the packet delivery ratio quantitative relation higher is that the performance of the node.
PDR= (Number of Packet's Transmitted) / (Total variety of Incoming Packets) 2. PMIR (Packet
Misroute Rate) –Node sends packet to the incorrect destination is name migrate information packet.
PMIR quantitative relation is that the variety of misread packet is delivered to the transmitted
packets. PMIR= (Number of Packet's Misrouted) / (Total Number of Incoming Packets). 3.

In recent times to keep up the network security is a foremost and the network is hacked by the
unofficial persons. There are various strategies to extend the safety similar to encryption and

Intrusion detection system. The Intrusion detection is the problem of identifying unauthorized use,
misuse and abuse of computer systems. Outside attackers are not only the problem, the threat of
authorized users misusing and abusing their privileges is an equally pressing concern. The intrusion

2) Most of the advantages of network based Intrusion detection system don't apply to small segment
of network i.e. switch based network. Monitoring range of switches are not universal, this limits the
network based Intrusion detection system monitoring range to single host.
3) Some network based Intrusion detection system have also problem in dealing with network based
attacks which involve the packet fragmentation. This anomalously fashioned packet triggers the
Intrusion detection system to change into unstable and crash. [3].
B. Host based System
A host–based Intrusion detection system monitors activities associated with a particular host [6] and
aimed at collecting information about activity on a host system or within an individual computer
system. In host based Intrusion detection system separate sensors would be needed for an individual
computer system. Sensor monitors the event takes place on the system. Sensors collect the data from
system logs, logs generated by operating system processes, application activity, file access and
modification. These log file can be simple text file or operation on a system.

Florida's Water Issues: Saltwater Intrusion
Florida's Water Issues – Saltwater Intrusion Saltwater intrusion leading to contaminated drinking
water wells has long been feared in South Florida. Saltwater intrusion occurs naturally to some
degree in most coastal aquifers, owing to the hydraulic connection between groundwater and
seawater. Because saltwater has a higher mineral content than freshwater, it is denser and has a
higher water pressure. There are three primary mechanisms by which saltwater contaminates the
freshwater reservoir in the unconfined, surficial aquifers of the region: one, subsurface movement of
seawater (lateral large–scale intrusion), two, seepage of seawater from tidal canals and streams, and
three, upward movement of connate saltwater (water remaining from the ... Show more content on

Among these events are the initial operation of the Northwest Well Field and a consequent reduction
in pumping from the Hialeah–Miami Springs Well Field, expansion of the Southwest Well Field,
and changes in the delivery schedule of water to southern Dade County and Everglades National
Park. Chloride concentrations in water samples collected from existing monitoring wells in
northeastern Dade County have indicated little, if any, inland movement of the saltwater interface
since 1984. The saltwater interface in northeastern Dade County is shown in approximately the same
location with differences due to more information being available and not to any perceived
movement of the saltwater

Igneous Intrusions Within The Raton Basin Sierra Grande
Igneous intrusions
A period of volcanism resulted in igneous intrusions within the Raton Basin–Sierra Grande Uplift
Province that was sourced from the upper mantle about 26. 6 billion years ago and is associated with
parallel dikes and sills (Higley, 2007). Igneous rocks are common within the Raton Basin and
include Tertiary dikes and sills that range in age from 6.7 to 29 5 million years ago (Flores and
Bader, 1999). One of the main differences between dikes and sills is that dikes are longer lived
magma conduits and sills are features that form when magma is in neutral buoyancy with the
surrounding rock (Rooper et al., 2006). These volcanic events are associated with hydrothermal
alteration of coal within the basin (Higley, 2007). ... Show more content on Helpwriting.net ...
Intrusions within the coal–beds in the northern part of the Raton Basin have been destroyed in vast
amounts (Johnson and Finn, 2001). Sills and tabular igneous bodies parallel to bedding are intruded
in the middle part of the Raton Formation and are exposed in the Purgatoire River Valley (Watts,
2006). Sills within the basin intrude along a coal–bed instead of through the coal–bed, influencing a
larger volume of the coal (Rooper et al., 2006). The sills in the basin are fine grained and distributed
across the subsurface as well as intruded into the coals (Pillmore, 2003).
The igneous intrusions in the Raton Basin provide a high temperature and pressure environment
promotes an increase in generation of gas (Jian and Cheng, 2014). No evidence suggests that the
different intrusions within the coal were at different temperatures (Rooper et al., 2006). It has been
suggested that the heat from the dikes enhance adsorption and porosity in coals and also increase the
trap capacities of gas storage (Jian and Cheng, 2014). Igneous intrusions create safety problems in
the mines underground and the gas created could result in the projection and rapid release of gases
(Jian and Cheng, 2014).
Coal–Bed Methane and Natural Gas.
Coal–bed methane is naturally occurring methane with some amounts of hydrocarbon gas as well as
non–hydrocarbon gas that is contained in coal seams resulting from chemical

Intrusion Prevention System
Intrusion Prevention System (IPS) is a proactive protection technology that provides security at the
network level. It's the first line of defense against malware. An organization can not protect their
network with just a firewall. Additional protection is needed to avoid potential risks and attacks. An
Intrusion Prevention System adds the extra layer of protection by examining all network traffic that
is allowed through the firewall. Previously Intrusion Prevention Systems simply protected operating
system threats or denial of service and distributed denial of service attacks. These threats exploited
vulnerabilities that were mostly in the operating system stack and services. Over the years these
operating system components have ... Show more content on Helpwriting.net ...
Any areas on the business's infrastructure or applications are risk areas. Typically, IPS devices are
deployed behind firewalls and WAN routers, in front of server farms or similar collections of
resources, and at other network access points. The IPS architecture in this paper shows protection at
the point of internet access, desktops accessing application servers, database servers, as well as
protection at the e–mail server and DNS server. These are the typical target areas where extra layer
of protection is needed. With the different sensors in place, the network administrator can not only
tune the IPS against attacks, but also balance network traffic and alert the network administrator
when a threat or attack is happening, and then taking proper action. In conclusion a successful IPS
design and deployment will require understanding the needs of the organization's system for real–
time threat protection, determining the right placement points for your IPS deployment, taking the
time to tune your system correctly, and doing an evaluation of your overall system and use. You
want to provide the best protection for your company's system, and limit the means of threats and
attacks. Deploying an IPS along with other protection devices and software would help in lowering
the organization's

The Decision Tree Method For Intrusion Detection System
Abstract
There are many risks in using the internet irrespective of its popularity. These risks are network
attack, and attack method which vary every day. This research is aim to compare decision tree
method for intrusion detection. As intrusion detection is one of the major research problem in
network security. Tradition intrusion detection system contain a number of problems, such as low
performance, high false negative rate, low intelligent level. In this research work we compared
effectiveness of decision tree method in Intrusion Detection System. We also compare the detection
rate, false alarm rate for different types of attack.
1.0 Background
Intrusion Detection Systems (IDS) are software or hardware designed to automatically monitor
activities within a network of computers and identify any security issues . IDS have been around for
at least 30 years since increased enterprise network access produced a new challenge, the need for
user access and monitoring. As day–to–day operations grew increasingly dependent upon shared use
of information systems, levels of access to these systems and clear visibility into user activity was
required to operate safely and securely.
Many of the initial headway on IDS was made within the U.S. Air Force. In 1980, James P.
Anderson, an innovator of information security and member of the Defense Science Board Task
Force on Computer Security at the U.S. Air Force, produced "Computer Security Threat Monitoring
and Surveillance," a

The goal of intrusion detection is to monitor network assets, detect anomalous behavior, and identify
misuse within a network (Ashoor, Gore, 2011). An intrusion detection system (IDS) is a device or
software application that monitors network system activities for malicious activity or policy
violations and produces reports to a management station (Kashyap, Agrawal, Pandey, Keshri, 2013),
additionally there are three types of IDS:
Host based IDS – monitors a computer system on which it is installed in order to detect intrusion or
misuse by analyzing several types of logs files including kernel, system, server, network and
firewall logs, and compares logs with signatures for known attacks.

Intrusion Detection System ( Ids )
Abstract–Increasing attacks and intrusion of the Internet and computer systems necessitate the need
for Intrusion Detection System (IDS) to prevent attacks. Genetic Algorithm (GA) is applied to
support IDS. Fitness function and GA operators–crossover, mutation, and population representation–
play an important role in improving the performance of an IDS: high detection rate, and low false
positive rate. This paper suggests a Fitness Function using Reward–Penalty technique that rewards
the good chromosome and penalizes the bad chromosome, for improved performance. We suggest
that the GA parameters be optimized for better IDS performance.
Keywords–Intrusion detection; genetic algorithm; fitness function; detection rate; false positive rate.
I. INTRODUCTION
Intrusion can be defined as the actions that attempt to compromise the integrity, confidentiality, or
availability of a computer resource [1]. Intrusion Detection System is a software or device to
discover the intrusion activity. Based on detection process, IDS can be classified into two groups:
Anomaly detection, and misuse/signature detection. Anomaly detection looks for rare or unusual
network activities, while misuse/signature detection uses past well–known attack patterns–
signature––to identify illegal activities. This paper deals with only misuse/signature detection in
computer networks. Network attack types can be categorized into the following groups:
Denial of Service Attack (DoS): A DoS attack makes the computer

spring evening. It was about half past nine and it was quiet, well besides the few late night trick or

of the delinquents of Glendale, Utah. It was dark by now and the street lamps were mostly all

Course this action was swiftly met by a real gun in both of our faces. Surprised we both stumbled
back a little as the guy said, "what you want". We both immediately dropped our guns to the ground
hoping our plastic pieces of shit didn't break on the concrete, thankfully they didn't, and our hands
went into the air. Gideon having a sack over his head with little to no visibility in the dark was
entirely oblivious to his surroundings. Not knowing what was going on the idiot piped up, "what's
going on guys we aren't at another house yet". To which we quickly told him to shut up and the
person whom had the gun to our heads seemed to notice the threat we gave off was not nearly as
immense as it seemed before and he just gave what I think was a slight chuckle but his tone
immediately changed back to being stone cold and he growled "watch it kids". We then stepped
aside pulling Gideon by the sleeve out of the way him and his gang walked past us for what felt like
an hour and we both just stood their a little shaken up that we could've both just died that

Rainy Lake Wrench Zone ( Rlwz )
Rainy Lake Wrench Zone (RLWZ)
Most known mineral occurrences in the RRB are in the RLWZ, as it is the best exposed and most
explored part of the block. Modest gold and silver production occurred here in the past (25,000 oz
Au; 3,000 oz Ag) and magmatic sulfide deposits have been outlined in the Grassy Portage intrusion
(two separate mineralized zones: 300,000 t @ 1.89% Cu and 300,000 t @ 0.8% Cu; Poulsen 2000).
The RLWZ also hosts VMS–style prospects in a bi–modal volcanic pile that is underlain by a
composite trondhjemite–tonalite–gabbro–anorthosite intrusion. Zn is predominant in this volcanic
complex, with lesser Cu, indicating shallow water and (or) low temperature mineralization process
affected the rocks. Au has been documented in the volcanic pile, but may represent orogenic style
mineralization. These metal assemblages and the geometry of the volcanic pile are similar to
Sturgeon lake VMS camp (e.g. Hudak 2003), indicating it has potential for hosting economic Zn–Cu
deposits. However, the atypical lithologic make–up of the composite subvolcanic intrusion (i.e.
anorthosite–dominated) does not match well–endowed VMS camps (Galley 2003) and the proximal
high–grade metamorphism (amphibolite facies) and strong deformation (shearing) may have
compromised the preservation of hypogene mineralized zones. If mineralized zones are preserved,
they could be Au–rich, as the structural setting (bounded by crustal–scale faults) and inferred
paleotectonic setting (rifted arc or

Saline Intrusion Effects
Saline intrusion is the movement of saline water into freshwater, which can lead to contamination of
drinking water sources and other consequences. This is a serious issue that we face today, but with
the right actions the public can put an end to it. Salinization on the coast can lead to the increase of
sodium ions in soil and water. This is important because high salt levels can affect osmosis, the
process by which some organisms, such as plants, take up or give away water. As the number of salt
ions in the surrounding environment increase, water will flow out of an organism towards the higher
concentration, causing dehydration and death (Molly Webster, 2007). Saline intrusion is not a new
issue that has been occurring, it has been going ... Show more content on Helpwriting.net ...
The question to ask is how does saline intrusion effect different plants? In this experiment, we have
three different species of plants that we measure every week. The experiment should show how the
salt water effects the different plants that have never been exposed to salt water. My hypothesis is
that the water with 1.25M or higher will die much faster than the those of lower concentration, but
eventually all of the plants with saltwater will die. High concentrations of salt water will have a
much greater effect on the plants will take in more of the substances that are harmful to plants and
therefore, will kill them, especially faster then those of lower concentration. If there is lower
concentration of salt in the water, then the plants will die much

An Intrusion Of American Elements
the "enemy". This intrusion of American elements replaces not only Chinese elements, but also the
Vietnamese cultural identity.
Contemporary culture, however, plays a different role. As current contemporary movies, music,
visual arts and other entertainment forms produced by Vietnamese resolve around the Vietnamese
"national cultural identity", which almost always incorporates Chinese elements or Chinese
influence in some ways: in its language, practiced customs, art motifs, etc., as addressed. Vietnam's
contemporary culture, in this condition, has the same low probability of dividing between the
Chinese elements and "quintessentially Vietnamese". However, in reality, the concept of
"Vietnamese contemporary culture" does not only include productions by Vietnamese people. As the
Vietnamese community reacts and corresponds to foreign cultural productions as engagingly as they
do with Vietnamese–produced goods, this country's contemporary culture encompasses these alien
productions. In this context, culture is more easily categorizable. Additionally, making the first step
in protesting with contemporary culture is a logical movement. Unlike other goods exchangeable
economically, which can be manipulated to present as if from a different origin, Chinese
contemporary cultural productions take significantly distinct forms. As they are very
distinguishable–the use of Mandarin's often a giveaway–differentiation of Chinese media and
entertainment production becomes the simplest,

Anne Sexton Metaphor
Daniel Jung
English 1114: 003
01 October 2014
Poetry is a Code; The Key Often is Metaphor:
Anne Sexton's "You All Know the Story of the Other Woman Poetry is an art form that is rich in
notional and semantic content. In a few stanzas, poems are so capable of painting an idea or event so
vividly that it seems alive. However poetry, by itself, cannot exhibit qualities of life: they require a
willingness to understand unfamiliar ways of describing a phenomenon. Thus poetry has been
likened to a scrambled code that is impossible to decipher in its literal context. Thus, poetry requires
a key to decipher it and the code, often, is metaphor.
In "You All Know the Story of the Other Woman", Sexton first introduces the setting claiming that
"It's a little Walden" (Sexton, 1). The "little Walden" (1) is the first key that assists in decoding the
Sexton's poem – it is a metaphor that refers to an isolated and tranquil residence. However the
following lines depict a scene of action, not peace, resulting in an ... Show more content on

By likening the man's actions as a body that "takes off and flies, / flies straight as an arrow" (3–4), it
is evident that there is a sexual interaction between a man and woman; however their relationship is
unclear. Analysing Sexton's choice of "arrow" (4) suggests that the woman is a one–time attraction
for the man because an arrow flies straight and is physically incapable of returning to the bow from
which it was strung. However, the metaphor does not reveal the relationship between the two, it can
only be assumed and thus, according to Sexton, it is "a bad translation" (5) which suggests that
although the metaphor is capable of describing the physicality of their relationship, it is ineffective
at describing the esoteric qualities. Thus it becomes glaringly apparent that a single metaphor is
incapable of completely unlocking the code of poetry – although it does, in part, decode some aspect
of the

An Intrusion Prevention System ( Anthem )
With another breach hitting the news (Anthem), I often wonder when companies will learn a lesson,
a right lesson even. What I found fascinating about the recent Anthem breach, was that it was an
employee of Anthem that discovered that something was wrong. Not a firewall, not an intrusion
prevention system, not an intrusion detection system, not a web application firewall, or any other of
the dozens of technologies I could mention. According to news reports [1], a database administrator
noticed queries made with his/her account, that they never made. The employee reported it, and the
trickle effect occurred spurring the notification of Anthem being breached. Kudos to the alert
employee, and shame on the technology that failed Anthem. That in itself – "shame on the
technology" – was not a fair statement but was somewhat meant to get your attention. Did it work?
For all of the technology corporations throw into an infrastructure to prevent, mitigate, detect, and or
correct breaches, why is it that so many are failing? I could quickly point a finger at any vendor,
product, or technology but the reality is, and will continue to be, people failed. The thought
processes from the professionals whose task it is to secure an infrastructure often lag so far behind
the curve I wonder if many are fit to associate the word security in their profession. It will not matter
what technology is put in place if the threats are not fully understood. This in itself is also a problem

Essay Intrusion Detection Systems
Intrusion Detection Systems
In 1980, James Anderson's paper, Computer Security Threat Monitoring and Surveillance, bore the
notion of intrusion detection. Through government funding and serious corporate interest allowed
for intrusion detection systems(IDS) to develope into their current state. So what exactly is IDS? An
IDS is used to detect malicious network traffic and computer usage through attack signatures. The
IDS watches for attacks not only from incoming internet traffic but also for attacks that originate in
the system. When a potential attack is detected the IDS logs the information and sends an alert to the
console. How the alert is detected and handled at is dependent on the type of IDS in place. Through
this paper we ... Show more content on Helpwriting.net ...
With NIDS the system attempts to detect threats and attacks, such as denial of service attacks, port
scans and attempts to hack into computers by monitoring the network traffic in real time through a
promiscuous connection. It does so by first filtering out all known non–malicious traffic and then
analyzing the remaining incoming packets for suspicious patterns that could be threats. It is not
however limited to just analyzing incoming packets, the system also analyzes the outgoing local
traffic, in case of an attack/threat that originates inside of the local network. Snort is an example of
this.
Host based intrusion detection systems unlike network intrusion detection systems, which focus on a
computing system's external interfaces, host based systems focus on the monitoring and examination
of the computing system's internals. Host based systems are more concerned with the changes in
state of a computing system. It detects these changes by analyzing system specific logs either in real
time or periodically. When there is any change in the logs the IDS will compare the current
configuration of the security policy to the changes and react accordingly. An example of this would
be tripwire.
Protocol based intrusion detection systems (PIDS) monitor the dynamic behavior and state of the
protocol. In a typical setup there is a system or agent sitting at the front end of the server. This agent
or system monitors the communication protocol between the

A DECISION TREE BASED RULE FORMATION WITH COMBINED PSO–GAALGORITHM
FOR INTRUSION DETECTION SYSTEM
3.1 INTRODUCTION The increase in the usage of the computer networks leads to the huge rise in
the threat and attacks. These attackers change, steal and destroy the valuable information and finally
cause complete damage to the computer system of the victim. They affect the performance of the
computer system through the misconfiguration activities and generation of software bugs from
internal and external networks. Irrespective of the existence of various security mechanism,
attackers often attempt to harm the computer system of the intended legitimate users. Hence,
security is a main factor for the efficient operation of the network in various applications such as
healthcare monitoring, military surveillance, etc. The most common security mechanisms are
firewalls, antivirus programs and Intrusion Detection System (IDS).
Firewalls (Fehr, 2013) are the commonly used mechanism for securing the corporate network or
sub–network. The firewall is operated based on a set of rules that can protect the system from the
flooding attacks. The main function is sorting of the packets according to the allow/deny rules,
based on the header–filed information. But the firewalls cannot ensure complete protection of an
internal network, since they are unable to stop the internal attacks. The computer viruses can cause
damage to the computer data that leads to the complete failure of the

Intrusion Detection Systems (IDS) Software
An intrusion detection system (IDS) monitors' network traffic, monitors for suspicious activity, and
alerts the system or network administrator. In some cases, the IDS may also respond to anomalous
or malicious traffic by taking action such as blocking the user or source IP address from accessing
the network. IDS come in a variety of "flavours" and approach the goal of detecting suspicious
traffic in different ways.
Network based (NIDS) and host based (HIDS) intrusion detection systems. There are IDS that detect

Reactive IDS, will not only detect suspicious or malicious traffic and alert the administrator but will

The Virtual Intrusion Detection System
The Virtual Intrusion Detection System a traditional IDS is only an element in the security chain
architecture. It does not eliminate the need for protections to prevent attacks. The virtual intrusion
detection system (V–IDS) is a disruptive idea for the security of cloud architecture. Virtual IDS is
software and sometimes hardware that captures cloud network and host activity data in reporting
tools, analyzes the data interactively, provides an automatic reaction (e.g., alarm) during an incident,
and after an incident routes the cloud data to a security channel defined at runtime. Figure 4.2:

In the V–IDS context, the module uses two different methods for analysis: The attack signature
represents the simplest way to analyze IDS data. It is like static packet filtering, which is similar to
the firewall rationale. Anomaly detection (heuristics) represents the most sophisticated technique,
in which heuristic patterns try to detect variations from historically normal operation. 4.6.2 Decision
module The decision module is part of the close chain control system that, using the data which has
arrived from the analysis module, makes decisions about the real time actions necessary to solve
anomalies related to network intrusions. This module implements the logic necessary to analyze
behaviors and makes decisions about the anomalies discovered. 4.6.3 Action module The action
module represents the actuator that solves the intrusion detection situation on a cloud domain.
Merely collecting and analyzing data accomplishes nothing. The V–IDS uses the results from the
analysis in order to manage the cloud infrastructure on the basis of security. Most obviously, it also
generates alarms, reports and queries if the analysis indicates a dangerous condition. 4.6.4
Monitoring module The monitoring module captures (continuously) processed data from previous
events, such as historical intrusion data, login attempts, and so on. Each event is 20 time–stamped

Network Based Intrusion Detection Systems ( Idss )
Abstract: Providing security in a distributed system is important as cloud computing provides
variety of convenient services. IDS implementation in cloud requires an efficient, scalable and a
constructive approach. Many Network–based intrusion detection systems(NIDS) are used for the
reception of packets from the cloud, but those systems possess lower detection rate, high false
positive rate and they fail to resist single point attack. I would like to propose one method which I
encountered and found out to be efficient compared to other methods. This unique model has
multiple intrusion detection systems (IDSs) that are deployed in each layer of the cloud
infrastructure for protecting each Virtual Machine against threats. Another catching feature is that of
cloud alliance concept which exchanges mutual alerts to resist the single point attack of failure.
Introduction Cloud Computing The term cloud is analogical to Internet. Similarly cloud computing
is a model for delivering information technology services in which resources are retrieved from the
internet through web–based tools and applications, rather than a direct connection to a server.(Corey

The ideal characteristics of an Intrusion detection system are:
It must work continually with minimal human interference
It must be error free by being able to recover from system crashes, either accidental or by malicious
activity.
Upon startup, the intrusion detection system must be able to recover its previous state and resume its
operation unaffected.
It must resist subversion. The intrusion detection system should be automated by monitoring itself
weather it has been compromised by an intruder
It must impose a minimal overhead on the system where it is running, to avoid interfering with the
system's normal operation.
It must be configurable according to the security policies of the system that is being monitored.
It must be adaptable over time to the advances. For example, new applications being installed, users
changing from one activity to another or new resources being available can cause changes in system
use patterns.
As the number of systems to be monitored increases and the chances of attacks increase we also
consider the following characteristics as desirable:
It must be scalable to monitor a large number of hosts while providing results in a timely and
accurate manner.
It must provide graceful degradation of service. If some components of the intrusion detection

system stop working for any reason, the rest of them should be affected as little as possible.
It must allow dynamic reconfiguration, allowing the

Kevin Mitnick, The Condor, The Darkside Hacker, The greatest hacker alive, whatever name he was
given that pins him down as a perpetrator of the law, Kevin Mitnick still serves as an educator to
enthusiasts in the world of Information Security. He unveils many secrets of the hacker in The Art of
Deception. The Art of Intrusion takes a different twist from its predecessor. It looks at the attitude of
the hacker and what drives them.
Personally the book lacked the full degree of intrusions one is capable of. Looking at the resume
Kevin Mitnick has, successful intruder, phenomenal social engineer, most wanted of the law, caught
and convicted criminal, security consultant and finally company CEO, one would have expected his
personal experiences and intrusions that finally landed him as the greatest hacker ever known by the
media. With this the book lacked some sort of uniqueness because it was based on other stories of
intrusions.
Mitnick took different stories and merged lots of information through them which in turn ended up
being more of an introduction course to types of security breaches than an in depth look at how
hackers can breach security. This showed some form of incompleteness especially to a technical
audience. For the non–technical it serves as a good read but not much is learnt and gained by the
technical audience so I feel the target audience was blurred out. The stories seemed very fictional
which again raised the suspicion of whether they were really true or

The Best Exposure Of Rocks
The best exposure to of rocks can be seen in road cuts, because they the great variety in the rock
types and formations within the area. Stray fragments of rocks can be found in mass quantity
alongside the river, held back from the road by barriers, or as a cut face that is parallel to the road.
You can clearly see the different intrusions along the roadside, dikes running along crevices, and
many instances of solid rock blasted in order to clear a way for the road. These mass capacities of
the same rock are plutons that have been uplifted over geologic time1. Tonalitic plutons consisting
of primarily granodiorite and quartz are all over the Cascade Range, forming the Grotto/Index
(~25m.y.) and Snoqualmie (~18m.y.) Batholiths of common rock types. More recent Swauk
sedimentary structures are seen as overlap from the nearby Blewitt (formerly Swauk) Pass region,
likely formed as result of the last ice age1,2,5. These sedimentary layers fade out deeper into the
mountains, as the igneous intrusions become more predominant within the range. White and black–
grained diorite is common and clearly identifiable as well as amphibolite if looking around the

3.4.1 Control Methods
Security controls include the utilization of technical and nontechnical strategies (NIST, 2002).
Technical controls are protections that are consolidated into PC hardware, programming, or
firmware such as access control mechanisms, ID, encryption techniques and intrusion detection
program or software). Nontechnical controls on the other hand are administration and operational
controls that includes security approaches; operational methodology; and physical and
environmental security NIST, 2002). SunTrust Bank should implement technical controls with
respect to how information and data are being encrypted, what program is being utilized to identify
any intrusion to their network and system and how customers/clients are being verified. Concerning
nontechnical control, SunTrust administration should provide appropriate security controls for every
resources and assets in the organization.
3.4.2 Control Categories
NIST classified both technical and nontechnical control techniques as either preventive or detective.
Preventive controls restrain attempts by the attackers to damage security strategy and policy such as
access control authorization, encryption, and validation (NIST, 2002). Detective controls, however,
should caution of violation or attempted violations of security such as audit trails, intrusion
detection methods, and checksums NIST 2002, p.20). Hence, SunTrust bank should endeavor to
enhance their intrusion detection system or IDS for

Cyber Surveillance And Intrusion Detection System Essay
Abstract
In this era of technology, everything is available at just one click; Security is a big issue when we
talk about networks. Hackers and intruders are getting smarter. There are various methods to secure
the network infrastructure and communication over the Internet, for example firewalls, encryption,
and virtual private networks. Intrusion detection is a relatively new approach to such techniques. By
using intrusion detection, we can collect and use information from known types of attacks and find
out if someone is trying to attack the network/host.
Keywords: intrusion detection system
I. Introduction
Intrusions are the activities that violate the security policy of system. Intruders may be from outside
the network or legitimate users of the network. Intrusion can be a physical, system or remote
intrusion. Intrusion Detection is the process used to identify intrusions i.e. a piece of software that
monitors a computer system or network resources to detect malicious activities unauthorized
attempts to use the system or abuse of existing privileges in a network or on a host system. It
identifies and stops attacks in progress and conducts forensic analysis once attack is over. It detects
intrusions and attacks that were not stopped by preventative techniques (firewalls, packet–filtering
routers, proxy servers. In this whole approach, determining 'who ' is much harder than just detecting
that an intrusion occurred. Figure: The role of Intrusion Detection in network

If the castle owner wants his castle to be protected, he has to know what his weaknesses are first.
His weaknesses can consist of how exposed the castle is to an attack, periphery in the sense of
measuring the extent of the castle walls and openings that susceptible to attack, lack of protection,
the threat of the approaching army, the actual attack done by the army, and the vulnerabilities of how
the castle can be breached in order for the army to gain access to the gold (Gatford, et al., 2007).
Human errors are the main vulnerability that the current network configuration has. Humans are the
ones who created and implemented the network system in the first place. Humans are obviously not
perfect and can create unknown vulnerabilities in the system when making it. All authentication
errors and misuses trace back to humans also. Unauthorized access, authentication misuse, and
authentication errors are also vulnerabilities that the current configuration has. By strengthening the
network system using a stronger system than the traditional ID and password system can reduce
unauthorized access to a minimum. Authentication misuse is prevalent due to some humans being
unethical. A way to counter these unethical people is to have people be more knowledge about
security policies and how to properly leave their workstation before they leave work for the day.

The 2009 Intrusion on Google's Network
The 2009 Intrusion on Google's Network
Technology is consistently evolving. With this evolution comes great new innovation that empowers
users all around the globe. However, it also brings completely new and ever–dangerous threats. In
2009, Google found that technology had brought such threats right into its networks. The company
was one of many that were targeted by a very highly sophisticated attack to steal intellectual
property undetected, rather than to just interrupt service or destroy data. Google had found itself a
victim of an international malware attack aimed at stealing source code and spying on human rights
activists in China. News of the attack first broke at the end of 2009 and the beginning of 2010.
Google was the first to announce that it had been a victim of such a sophisticated attack measure,
although it was certainly not the last. Essentially, a general overview of the intrusion illustrates that
Google was one many primary targets, as there were reports of over 34 technology, financial, and
defense companies that were also included in the attack (Zetter 1). The attacks were targeting
information, financial, and defense service companies utilizing very sophisticated and stealthy
malware codes. The entire attack was later known as Operation Aurora, and is one of the most
damaging cyber attacks in contemporary history (Zetter 1). It was dubbed this name by McAfee
due to the belief that this is the name the hackers used for their mission (Zetter 1).
