What is a Network?
Communication and information are the two most important concerns for an organization. Today¡¦s
organizations use a number of computers and communication tools (telephone, faxes, internet) to
help them function in their daily operations. Communication is crucial among departments, and
information and data throughout the organization needs to be easily accessed in order to allow for a
steady workflow. To overcome these obstacles, computer networks are necessary. Computer
networks allow the user to access programs and databases, and it provides communication
possibilities faster than other methods.

The drawback to a LAN is that there is a limit to the distances that computers can be shared and to
the amount of computers that can be connected to it. LANs can vary in size. A small LAN might
connect a few computers, while a large LAN could connect computers throughout a few buildings.
Common speeds are 10Mbps or 16 Mbps.
In a WAN, computers are connected together through further distances by telephone lines or radio
waves. A WAN consists of at least two LANs. The largest WAN is the Internet. A disadvantage to a
WAN is that message transmission may be delayed, lost, or damaged. Messages are passed from one
computer to another until it arrives at the destination. Effective routing techniques are important to
network performance. A single message may travel by different routes and arrive at the destination
out of order. Typical transmission speeds range from 56 Kbps to 1.54 Mbps.
A MAN is designed for a town or city. MANs are larger than local area networks, but smaller than

also known, is the process of extraction of implicit information that previously unknown and
potentially useful from database. By using a number of different technical, such as clustering, data
summarization, learning classification, finding dependency networks, analyzing changes, and
detecting anomalies. Data Mining refers to a variety of techniques that can be used to analyses and

Network Traffic Networks And Intrusion Prevention System
Introduction
Network traffic analysis shows that a single host is opening hundreds of secure shell (SSH) sessions
to a single host every minute. What can we do to stop it?
OWDSI has to perform the following which is in the event that SSH is not being utilized on the
personal computer then close the open port, which is port 22. On the off chance that the port needs
to stay open then make sense of the IP address that goes through the port and afterward shut the
open, however open it for the IP Address as it were. Since the host is attempting to open such a large
number of sessions to the next host the principal thin that rings a bell is a refusal of administration
(DOS) assault. Intrusion Detection System and Intrusion Prevention System can be utilized to
remember this assault and after the drop all parcels from the primary personal computer (PC) to
keep the assault from proceeding.
Network traffic shows that hundreds of hosts are constantly sending only synchronized (SYN)
packets to a single web server on campus. What can we do?
OWDSI has to run a report on the security protocol and their security and have all the personal
computers (PC) do a full sweep after the shift it's over. The explanation is that this is a typical attack
of DOS known as a SYN Flood. The assailant utilizes a satirize IP deliver that interfaces with
nothing and afterward sends a huge amount of parcels to the objective. The objective gets the

Honeywell technology leads the way with their Hart and One Wireless Networks. They use asset
management solutions to provide customers with ultimate flexibility. Honeywell brings immediate
benefits to the industry by cost–effectiveness, empowering a mobile workforce, plant security with
wireless cameras and connects remote controllers to the central control systems (3). Honeywell has
always offered free and simple access to application upgrades from their websites (4). Its technology
has been implemented from the field to the control room. The one wireless device has a self–
discovering and self–organizing managed and secure wireless field instrument mesh network. They
talk to each other and bridge the wireless network together. They use the IEEE 802.11 standard that
increases the network performance and improve air quality. The instruments in the field send data
through neighboring instruments back to the gateway device. This is used for non–critical
monitoring and they do not require a fast update rate. The more the instruments the faster the update
rate, this could be as fast as one a second. There is a pitfall to these devices and that is battery life,
but this can be alleviated with adding more access points. Most of the time users get three years
battery life from their field instruments while using a one second update rates.

Preventing Attacks on New Network-Based Systems
Preventing Attacks on Nee Network–Based Systems Introduction Recent changes in the
organizational structure of the IT system has left open needs for adjusting practices in order to
address new demands of protection. The organization has recently made the move from a standalone
system to a network–based one, which facilitates greater cooperation and collaboration within the
company and increasing overall productivity. A network–based system provides a more flexible
structure to still function within a diverse and multifaceted environment. It does so by the fact that
within its structure, "communication between components is restricted to message passing, or the
equivalent of message passing is a more efficient mechanism can be selected at runtime based on the
location of components" (Fielding, 2000). Network–based systems allow communication and
dissemination of information to occur seamlessly without lag. This then further empowers
individual employees of the organization with greater technological tools. The research suggests that
"network–based systems are those capable of operation across a network, but not necessarily in a
fashion that is transparent to the user," but rather as an automatic process that increases the ease and
productivity of each user while working on the system (Fielding, 2000). As such, it comes with a
wide variety of benefits to increase the productivity and efficiency of the organization. Analysis

To use information stored in AD DS such as user account and security groups, CA's will be
integrated into active directory either to approve or deny certificate request. When a certificate is
issued, the Enterprise CA uses information in the certificate template to generate a certificate with
the appropriate attributes for that certificate type. CA's will also provide users with a centralized
storehouse to request certificates. (Shinder, Diogenes, & Shinder, 2013).
Sample CA
With the larger number of users and resources across the entire network infrastructure, the
implementation of an enterprise CA will be an effective and efficient way to provide certificates to
users and devices. Enterprise CA can provide certificates from both forests in a more secured and
managed environment.
Federation services
For single sign–on functionalities on partner's location, IMI will install and configure windows
server federation service. AD FS is a standards–based service that allows the secure sharing of
identity information between trusted business partners across an extranet. With ADFS, the company
can manage its own user accounts, allowing users only have to remember one set of credentials.
Those credentials, however, can provide access to a variety of applications is located in different
locations.

The world is full of technology, in this ever growing world this technology needs to be connected.
Everything is interconnected through the internet nowadays. The internet is the connection of
assorted computer networks through a series of service providers and businesses. In order to create
these networks, there needs to be devices known as routers, switches and firewalls. These devices
have some very well–known vendors, such as, Cisco and Juniper. Juniper uses an operating system
called Junos. Junos OS is a great network operating system because of its modularity and it's unique

Ciarlone say in a statement "One of the first things that Juniper realized was that, due to Cisco 's
monolithic pricing, smaller businesses were being shut out of high–end networking almost entirely"
(Ciarlone). He goes on to say that using Juniper products are great for small to medium sized
networks. Cisco has moved up to higher tier networking and thus their equipment has upped in price
as well (Ciarlone). Juniper is aimed at not only the big networking side but also heavily caters to the
small scale network side. The devices range in different tiers of price and ability. The biggest
difference has to be the price in the products. The price of a product can make or break a company's
network infrastructure; not all companies can budget themselves for the greatest network
infrastructure. Jim Duffy compares and contrasts these two networking giants and points out many
differences, Jim goes on to quote Jeff Doyle, the president of IP consultancy Jeff Doyle and
Associates saying "The reality is, IOS is pretty old. [JUNOS] was architecturally designed
differently. It 's more modern and modular, meaning bug fixes are easier and functional failures tend
to be not as impactual as they are with as IOS." (Duffy). The modularity of Junos is what makes it a
cut above the rest. Junos has a modular OS, Junos uses separate module to do the specified

If a process took 45 minutes then the user would have to run 2 blocks simultaneously, taking up 1
hour, this means 15 minutes would be wasted, as the process wouldn't actually take that long. This
means that running a number of processes would take too long. This is considered Phase 1 of
Operating systems and is called Serial Processing Phase 2 consisted of batch systems, and was
called Simple Batch Systems. This was one of the first OSs that removed the user access to the
hardware; there was no longer any direct access, meaning there was less human error, and possible
reducing the time it took to start the systems up. This OS functioned by allowing a submission of
'Jobs' to a Computer Operator, who would collate group jobs into a batch. These batches are then put
into a program, allowing the process to take place. This reduced the number of pauses caused
between each batch, allowing faster processing times. Multi–Programmed Batch Systems was an
upgrade of Simple Batch Systems. This phase allowed automatic sequencing, which removed the
gaps between each batch/job, however the processor was very often idle. Using this system also
meant that Input and Output devices took their time; waiting around for them to load would waste a
lot of time. As this phase also contains Multiprocessing it allows the OS to switch between jobs
while an active job is waiting. The final phase of the OS is Time–Sharing. This was again an

In general terms, overhead means anything extra that shouldn' t be. So what is overhead in
networking or how it's affecting the entire network performance? It does not seem irrelevant for us
to know something that most of us deal in everyday life knowingly or unknowingly. The technology

displays the distance between my home routers and the connected servers located in five different
states. This screen shot also establishes the point why and how overhead is affecting the networks. If
we analyze the data on that image, we will see that the server located in the greatest distance is
suppose to have higher latency but less download and upload speed. But that's not what we see from
the highlighted part of the image, right? Sever located in PA has 100 miles less distance than the
server located in NY. But the PA server shows the higher latency and less bandwidth speed for

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.

that modern operating systems are tightly coupled with networking, and that administration of a

course consistent with the current curriculum standards, while at the same time raising the profile of
the role of IS majors in system and network administration. Our course teaches the fundamental
principles of operating systems and networks, but with a decidedly information systems slant. The

Radio Network Performance For Indoor Cellular Systems
Radio Network Performance for Indoor Cellular Systems Keshav Kumar Bollu (M547X932)
Abstract– Indoor wireless systems with cellular technology provides good coverage and high
capacity with great potential if a large number of small radio–ports are connected to a centralized
radio network controller. Various radio network solutions are investigated based on this approach.
Architecture of a base station sub–system (BSS) is presented and the proposed BSS is based on a
distributed architecture. The cost economical solution for indoor wireless deployment is presented
that meets indoor capacity need and provides good indoor coverage. Antenna hopping is done,
which transmits information continuously on different antennas. The Radio Resource ... Show more
High traffic capacity is achieved with smaller cells and microcell systems which cover downtown
hotspot areas. Microcells are characterized by lower antenna heights and lower power levels when
compared with ordinary macrocells and hence offer high outdoor traffic capacity but low indoor
coverage. Thus an indoor system should supply better coverage and high capacity simultaneously.
These needs are fulfilled by using a large number of small radio–ports into the cellular system.
Several solutions are available to increase the system capacity: frequency reuse by reducing the cell
size, dynamic resource allocation, slow frequency hopping, hierarchical cells etc. The transmission
link performance is a key property of a wireless communication system as it determines the
coverage of the system. An improvement of the transmission link performance provides a cost–
effective way of increasing capacity by allowing reuse of tighter channel. A method of improving
the transmission link performance of a wireless communication system is discussed here. These
needs are satisfied by arranging a huge number of small radio ports to the existing cellular system.
Spot coverage is provided for those areas which are hard or impossible to cover with the outdoor
cells. The radio–ports transmit with very low power for a small coverage area and keeping the
generated interference low. The reuse of traffic channels between the small areas covered by the
radio–ports can possibly be very frequent

One of the first things that comes to mind is the administrative and clinical staff are complaining
about how "slow" the network is. With an increase in staff over the years at the hospital and an
increase in the demand of the network and the existing system is struggling to keep up. Staff are
complaining about the weak and slow speed of the network at the hospital. Along with the problems
of the network, staff are also having a hard time of being able keep patient medical records up to
date and patient billing correct.
2. What features should the new system have that the existing system does not currently possess?
The hospital's existing information system and network were designed many years ago when all that
it was mainly used for was sending email, using the internet for research, or saving files to a file
server. We would like the new information system and network upgrade to take advantage of being
able to have an information system where all patient medical records can be updated on a continual
basis, where medical inventory can be inputted into a patient inventory database to keep track of
what has or hasn't been used for patients, where patient billing is accurate and kept up to date and
accessible in real time. Where Clinical

Analysis of the Network and Communication Systems of...
The network and communication systems Jewell Instruments, LLC is a manufacturer of solenoids,
medical equipments, mechanical parts for aviation and several other equipments for various
purposes. Its IT department handles all equipments on the premises and individual end–user needs.
The network of Jewell Instruments consists of around 85 PC's, 5 main servers and connecting
equipments such as switches, routers and hubs etc. The Choice One Communications in Manchester
provide them the connection to the outside world through T1 line. In their Barbados office high–
speed wireless connection is available through WAMCO Strategies. It has a Satellite access and
shares with other branches of their company. The facilities at Manchester and Barbados
communicate with each other through a private VPN, which is coupled with hardware in the DMZ
in both of the facilities. Net–screen is the software, which controls this communication. Due to this
system the salespersons of Jewell Instruments can connect to the network while they are on the road
and they are also able to look into their files and database and connect to an in–house terminal
server. In Manchester the T1 line is spilt so that facility may be provided to Panasonic PBX and at
the same time use the Internet with a TSU/DSU unit. This unit cascades to a Cisco 1601 Router and
then by using a specific network hub, the connection is transferred to the main switches and an
accelerated network box for the VPN. Jewell Instruments has two

Many lack uninterrupted power supplies or proper environmental controls. Network manageability
is important because library has a tradition of basing operations on small support staffs with high
productivity. Justification:– Library is interested in an upgrade to its network system. Students have
complained about occasional downtime and slow response times when accessing the network,
especially at peak access times. At a minimum, Library wishes to correct these issues through an
upgrade to their system, but management is also looking to be able to improve productivity and
increase security of the confidential data sent over their network. In addition to updating the
hardware, the proposed solution outlines some changes in the network configuration. These changes,
if implemented, will provide greater reliability and security for all users of the Library people.
Along with the new hardware, the new network configuration will open the door for library to
explore new possibilities in using the network to increase overall productivity and, in the end, better
serve the needs of their users. The solution outlined below will provide the greatest benefit possible
for student––meeting all of their current needs and providing for future expansion––at the lowest
cost possible. The total estimated cost for the project is just under $75,00,000; this takes into
account not only resolving

Benefits And Limitations Of A New Information System And...
The technology feasibility study has an argument that XYZ hospital 's current technology is
outdated and doesn 't meet current healthcare standards. The hospital 's network bandwidth is
capped because of the antiquated equipment and problematic wiring. Advantages and disadvantages
of the current network are that the current system will work with outdated technology. A
disadvantage is if the hospital is unable to acquire newer technologies which can have an effect on
effectiveness and efficiencies when the hardware and capabilities are not able to keep up. Security is
always of an issue. An argument can be made that a secured network will have enough security
controls to mitigate or negate the possibility of attacks from the outside. Inside ... Show more
An argument can be made that costs of newer technology will decrease significantly over time and
will allow XYZ hospital to take advantage of these technologies at lower prices.
PROBLEM STATEMENT
The problem is that XYZ hospital has identified the need for telemedicine and electronic health
record management capabilities but hasn 't been able to convey the costs and risks associated with
implementing an information system and network infrastructure upgrade. This is a problem because
the current and projected budget will possibly limit funding for equipment and development of a
new system.
PURPOSE STATEMENT
The purpose of this feasibility study was to examine the risks associated with the network and
information system and compared it to upgrading the current infrastructure. The information
produced from this research helped XYZ hospital convey the strengths, weaknesses, and impacts on
choosing a new networking and information system infrastructure. This is important because it will
give the hospital the information it needs to help prioritize projects that will allow the–the hospital
to continue to have a competitive edge in providing quality patient care and treatment through the
use of technology.
The XYZ hospital campus local area network includes the main hospital, an outer maintenance
building and an ambulance bay which include a lab, radiology department, surgery suites, intensive
care unit, pharmacy, 50 patient beds, emergency

Systems Administration and Network Administration
Systems Administration and Network Administration Systems administration and network
administration are, in many respects, very similar jobs. Both positions are highly involved in
maintaining the computer systems in an organization, and, in some smaller firms, the position may
be handled by the same individual. However, while there are significant similarities between
systems administration and network administration, there are differences in the roles as well.
Basically speaking, system administration focuses on computer systems and networks, while
network administration looks at maintenance and upkeep of the hardware and software that
composes the network (Entrance Exams 2012, 2012). Because there is obviously an overlap
between the two different job descriptions, it can be difficult to understand why it is so important for
information technology professionals to differentiate between network and systems administration.
However, when one understands the different roles of the two different positions, it becomes clear
that, why they might overlap, and why a single individual might be able to handle the position in a
small organization, there are actually substantial differences between the two positions. Particularly
in a large organization, the two jobs may need to be handled by different professionals with different
skill sets. It is because of these different skill sets that the industry has been so adamant about
differentiating between systems and network

Strategies and Plans in Executing Information Security
Introduction
Security has been playing a vital role in every sector. But the security is highly essential factor and
parameter in the field of Computer Networking Information system. Secured transmission of data
between sender and recipient is important for both the organization and its customers. High Point on
the security is very much essential so that appropriate strategies will be introduced, which not only
elevates business management avoiding risks in communication. Hence before implementing
computer information, security is a highly considered factor for both healthy business continuity and
an individual. This security is to be properly strategized before initiating the network. Here we
discuss the factors to be considered relative to the network security, challenges and strategies to be
planned before establishing a computer network.
STRATEGIES FOR SECURED COMPUTER NETWORK INFORMATION SYSTEM
A strategy for a secured information system should be principled on

Implementing Complex Protocols On The Network System
Introduction:–
In the present computer networks are being built by implementing complex protocols on an array of
network devices such as routers, switches and middleware like ISD intrusion detection systems and
firewalls systems. In order to allow the network to be modified to the changing environment, the
network Administrator have to manually configures all new configuration policies by converting
them into the low level commands that are supported by the system. Companies need to depend on
the network vendors in order to deal with the problems related to security, scalability, manageability
and other issues. Many efforts have been done to make the network programmable even before the
SDN. Some of those are Forces (2003), Routing Control Platform (2004), Ethane (2007), and Open
Flow (2008).
Main body:–
Network technology passed many stapes to reach the advance level it is now a days. The first step
was how to control a packet–switched network which started the project Forces which was
implemented in 2003. It has Protocols for multiple control elements and forwarding elements, the
project failed because it requires standardization, adoption, deployment of new hardware. After the
failure of Forces a new project have been applied called Routing Control Platform (RCP) which was
implemented in 2004.The RCP computes routes on behalf of routers, the RCP uses existing routing
protocol (BGP) to communicate routes to routers. The RCP Convert the best route of internal

The Immune System : A Complex Network Of Innate And Innate...
The immune system is a complex network of innate and adaptive compartments that work together
in order to protect and fight against pathogenic invaders. The immune system also acts as a regulator
of host homeostasis in order to ensure that the body is operating under optimal conditions. The
composition of microbiota is associated with the adaptive and innate immune systems, which work
together in order to maintain a constant relationship between the increasingly different microbiota
and pathogens found within our body.
Under optimal working conditions, the relationship between the immune system and microbiota is
interweaved between the innate and adaptive components of the immune system that cultivates an
appropriate immune response. Many immune related illnesses such as allergies, autoimmune, and
inflammatory disorders are all due to the failure in controlling misdirected immune responses
against self, microbiota–derived, or environmental antigens. Further, the use of antibiotics and
changes in diet also affects the composition of microbiota.
In terms of the relationship between the microbiota and immune system during development, the
fetal GI tract is said to be completely sterile. The first exposure the immune system has to bacteria
occurs when the child passes through the birth canal . The exposure that the immune system has
during this passage is what determines the long–term role of the mucosal and systemic immune
system . The maternal colostrum and breast milk

ABSTRACT
Mobile positioning technology has become an important area of research, for emergency as well as
for commercial services. Mobile positioning in cellular networks will provide several services such
as, locating stolen mobiles, emergency calls, different billing tariffs depending on where the call is
originated, and methods to predict the user movement inside a region. The evolution to location–
dependent services and applications in wireless systems continues to require the development of
more accurate and reliable mobile positioning technologies. The major challenge to accurate
location estimation is in creating techniques that yield acceptable performance when the direct path
from the transmitter to the receiver is ... Show more content on Helpwriting.net ...
2.1 ARCHITECTURE OF A GEOLOCATION SYSTEM
An example of geolocation system architecture [KOS00] is shown in Figure. As we said earlier, in
order to fix a call the subscriber we are calling must be located accurately. A geolocation service
provider provides location information and location aware services to subscribers. Upon a request
from a subscriber for location information about an MS, the service provider will contact a location
control center querying it for the coordinates of the MS. This subscriber could be a commercial
subscriber desiring to track a mobile device or a PSAP trying to answer an E–911 call. The location
control center will gather information required to compute the MS's location. This information could
be parameters such as received signal strength, BTS ID, TOA of signals, and so on that we discuss
later. Depending on past information about the MS, a set of BS's could be used to page the MS, and
directly or indirectly obtain the location parameters. These are sometimes called Geolocation base
stations (GBSs). Once this information is collected, the location control center can determine the
location of the mobile with certain accuracy and convey this information to the service provider. The
service provider will then use this information to visually display the MS's location to the
subscriber. Sometimes the subscriber could be the MS itself, in which case the messaging and

Detection Systems For The Network
As we know the computer network and communication has brought many sophisticated changes to
the networking world, But it also made the network systems vulnerable to attacks by hackers
anywhere at a distance. These attacks usually start by interrupting the network through some host
and encouraging further more attacks on the network. The hackers usually use sophisticated
techniques in interrupting the network, they use some softwares which will hardly use some
traditional techniques to hack the network. Therefore we need some detection systems to detect the
unusual data approaching the network. Therefore we discuss on two types of intrusion detection
systems , their development, principal, working and its pros and cons. In this ... Show more content

A littler framework can be setup for the single sensor to screen the movement by switch, passage or
switch. These intrusion detection systems are need in now a days on the grounds that it is difficult to
dependably follow along on potential treats and vulnerabilities of the computer organizing
framework. Today 's reality is changing and advancing with new advances and the web. intrusion
detection systems are tools which are situated in distinguishing the attacks and vulnerabilities in this
evolving environment. Therefore we need to curb these attacks by using intrusion detecting systems
to detect the attacks. Without these tools, it becomes very difficult and damage to the computer
systems. FIGURE 1: Computer network with intrusion detection systems Attacks can be partitioned
into two classifications Pre–intrusion activities Intrusions 1.2 Pre– Intrusion activities: Pre intrusion
activities are utilized to plan for intruding into a system. These incorporate port checking and IP
spoofing to identify the attacker or intruder. Port scans: A program will be utilized by programmers
to interface with the framework and figure out what TCP or UDP ports are open and vulnerable
against attack, which is called as scanner. These scanners will discover which PC on the system is
vulnerable against attack and focus the services running over the

Acceptable And Unacceptable Behavior When Using Company...
Acceptable Use Policy An acceptable use policy (AUP) is a document that a user has to agree to in
order to access the Internet or a corporate network (Rouse, 2014). AUPs outline what is acceptable
and unacceptable behavior when using company computer and network systems. An acceptable use
policy also outlines the disciplinary actions that will take place when someone violates the policy.
"Because the disciplinary process could lead to termination, the policy must be clear and concise
(Johnson & Merkow, 2011, p. 38)". An acceptable use policy creates a legal separation between the
employer and the employee (Johnson & Merkow, 2011, p. 38). When you sign up with an Internet
service provider (ISP) like AT&T, you'll usually be presented with an AUP, which states that you
agree to adhere to certain stipulations. The stipulations include not using the service as part of
violating any law, not attempting to break the security of any computer network or user, not posting
commercial messages to Usenet groups without prior permission, not attempting to send junk e–mail
or spam to anyone who doesn 't want to receive it, and not attempting to mail bomb a site with mass
amounts of e–mail in order to flood their server (Rouse, 2014). The purpose of the AT&T acceptable
use policy is to ensure that customers can use the network and the Internet without interference or
harassment from other users. "AT&T is at all times committed to complying with the laws and
regulations governing use of

Abstract
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
firewall. However these strategies are failed to detect the intrusions. For that a new technology is
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
detection system used data mining strategies for the network safety, as a result of to guard the
network from numerous assaults and malicious site visitors ... Show more content on

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.

The sole purpose of this report is to evaluate the current network and systems of IDI (Integrated
Distributors Incorporated) outlining some of the risks and vulnerabilities of the network as well as
providing recommendations for correcting deficiencies as well as strategies for mitigating said risks
to the system. Because IDI has suffered network breaches which led to the disclosure of highly
sensitive data in the past, it is necessary to ensure that further breaches do not occur in the future.
This document will help in that department. The information IDI has and uses needs to remain
confidential, unless the IDI feels the need to declassify said information. The information should not
be deleted on a ... Show more content on Helpwriting.net ...
The entire infrastructure is out of date including security patches and other upgrades. These has not
been implemented at each location which causes a major vulnerability which is more likely the
reason for these breaches within IDI. The equipment at the locations has proven that it is not
efficient for today's business needs as there are several instances of dropped connections and lost
sales during the peak hours of business. New software will be required to improve overall
performance and job duties. In conjunction to the new software, new hardware will need to be
implemented to work with the requirements of the new software. The security will also needs to be
improved which means that the out of date hardware will not be capable of the new requirements.
The data center in Billings, Montana is a great example of a bad infrastructure. Here is a general
layout supporting this statement. The data center has 14 UNIX servers, some of them are running
version 8.5, some running version 9 and some are running version 11. Windows based servers are
running Windows Server 2003. The office software is not uniform with some running Lotus, early
versions of Microsoft Office 5, some run WordPerfect 7, while others are running PC–Write. The
problem with this is that having all of these systems running different programs will prevent
information from being shared among other individuals in an efficient manner because the systems
may not be compatible with each

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

Virtual Private System : It Uses Public Network Essay
VPN
VPN are extremely regular utilized technique nowadays as a part of companies where they need to
keep communicate with their unreachable branches at some point in other piece of globe. It permits
authorization to get to companies Intranet in a protected and effective way. Virtual private system: it
uses public network to localise remote user or sites together. It uses internet to connect two networks
with each other. The VPN uses "virtual" connections routed via the Internet from the business 's
private network to the remote site or employee. By utilizing a VPN,company ensures security –
anybody capturing the encoded information can 't read it.
Why VPN's are essential?
VPNs give an essential support of organizations, governments, military associations, and even
people. VPNs give secure access to your local area network. Without VPNs, getting to delicate data
remotely would not be conceivable. VPNs permit two or more systems to communicate with each
other. For instance, a branch office of a bank situated in Papatoetoe and its home office situated in
Auckland associate with each other through the Web safely to share their assets, (for example, bank
statements, bank explanations, contract records, and so on.) together. With a VPN, both areas can
communicate together as one utilising the web safely.
Classification of VPN:–
VPN are classified into two types:–
site–to–Site VPN
Remote access VPN

Network Systems And Their Topology Essay
Network Systems
As one of the representatives of Corner Shop Realtor, I would like to present the advantages and
disadvantages of network systems and their topology. Changing the system of data management in
the company will allow the company to keep data more organised and secured, as well as give the
company opportunity to expand in other fields of business.
Network systems are divided into several categories, depending on their properties and use.
The smallest network is a PAN (Personal Area Network) – currently the most common is wireless
networks used in offices or homes, which typically includes a computer, printer and mobile devices.
This is a small personal network, used to transmit data at the lowest level, which can operate
independently of the Internet connection. The individual devices are connected to it, in most cases
using a Bluetooth or Wi–Fi module.
LAN (Local Area Network) is a local area network, which can be extended to multiple computers or
other devices, e.g. a larger office, hotel or apartment building. LAN allows its users to use the same
resources and applications, as well as transfer or exchange files. Communication can take place
using copper wires or wireless Wi–Fi, and can be independent of the Internet – as long as a network
card is available.
Individual LAN networks link to the larger network of MAN (Metropolitan Area Network), a
municipal network. The connection between local networks is via fibre optic cables, or radio waves.

Analyzing Networked Control Systems For Network Induced...
Abstract–Networked Control Systems (NCS) are the control systems in which the control loop is
connected through a communication channel. There has been an increased attention to the use of
Network Control System (NCS) in recent years because of their cost effective and flexible
applications. But one of the major issues that need to be studied and solved in NCS is the delay of
the data transmission which occurs throughout the communication network in the system and thus
degrades the control system performance and also causes the system instability. This paper basically
presents an analysis of network delay in NCS. In this paper, we have designed a model of delay
control system for network induced delay using the simulation model of network control system
delay and thus analysed the effect of network delay on the performance of the control system. The
TrueTime toolbox of Matlab/Simulink is used for simulating the NCS model.
Keywords–networked control system, network delay, control performance, truetime, stability
I.INTRODUCTION
In conventional control systems, control signals are sent over the loop using analog or digital
technology whereas in modern control systems, the control loop is closed through a real time
communication network by T. C. Yang et al. [1]. The Networked Control Systems (NCSs) are the
distributed control systems in which the system components (sensors, actuators and controllers) are
connected by communication networks [2]. One

Systems Administration And Network Services
1. Goal After two labs focusing purely on the Linux side of systems administration and network
services, this third lab puts Windows into the spotlight and how it deals with configuring services as
compared to the previous RHEL–based configurations. Many of the same tasks which were
completed using a RHEL 7 virtual machine in lab 2, such as setting up DHCP and DNS, are
repeated in this lab on a Windows 2012 Datacenter virtual machine. This is done not only to show
the differences in service administration, but also to indirectly teach students the steps as well as
precautions that need to be taken when integrating in different enterprise server operating system
families which very well could be running the same network services, such as in the case of this lab.
Instead of merely just installing the same services and letting the clients make decisions on what
data to receive from who, this lab also presents the challenge of making these two very different
operating systems work together when the time comes to configure the DNS server on the Windows
VM. A major point I took away from this is that while the Microsoft and ISC implementation of a
DNS server can be seen as widely different, the integration of the two is very smooth and easy due
to both of them still following the base rules of the DNS protocol as well as framework found in the
numerous RFC's which describe it. Active Directory, which is also installed on the server, was
