With the growth of computer networking, electronic commerce and web services, security networking systems have become very important to protect infomation and networks againts malicious usage or attacks. In this report, it is designed an Intrusion Detection System using two artificial neural networks: one for Intrusion Detection and the another for Attack Classification.
What is IDS?
Software or hardware device
Monitors network or hosts for:
Malware (viruses, trojans, worms)
Network attacks via vulnerable ports
Host based attacks, e.g. privilege escalation
What is in an IDS?
An IDS normally consists of:
Various sensors based within the network or on hosts
These are responsible for generating the security events
A central engine
This correlates the events and uses heuristic techniques and rules to create alerts
A console
To enable an administrator to monitor the alerts and configure/tune the sensors
Different types of IDS
Network IDS (NIDS)
Examines all network traffic that passes the NIC that the sensor is running on
Host based IDS (HIDS)
An agent on the host that monitors host activities and log files
Stack-Based IDS
An agent on the host that monitors all of the packets that leave or enter the host
Can monitor a specific protocol(s) (e.g. HTTP for webserver)

Database firewall is a useful tool that monitor databases to identify and protect against database specific attacks that mostly seek to access sensitive information stored in the databases. However the commercial database firewalls are expensive and needs specific product knowledge, while the opensource database firewalls are designed for specific opensource database servers.
In order to fulfill the need of inexpensive database firewall, Snort - an opensource IDS/IPS - is possible to achieve the goal in some scenarios with familiar rule writing. The paper will explain the limitation of Snort as a database firewall, constraints in commercial database statement and some example implementation.

An Intrusion Detection System (IDS) is a device or software application that monitors network and/or system activities for malicious activities or policy violations and produces reports to a Management Station. Some systems may attempt to stop an intrusion attempt but this is neither required nor expected of a monitoring system.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Event Management System Vb Net Project Report.pdfKamal Acharya
In present era, the scopes of information technology growing with a very fast .We do not see any are untouched from this industry. The scope of information technology has become wider includes: Business and industry. Household Business, Communication, Education, Entertainment, Science, Medicine, Engineering, Distance Learning, Weather Forecasting. Carrier Searching and so on.
My project named “Event Management System” is software that store and maintained all events coordinated in college. It also helpful to print related reports. My project will help to record the events coordinated by faculties with their Name, Event subject, date & details in an efficient & effective ways.
In my system we have to make a system by which a user can record all events coordinated by a particular faculty. In our proposed system some more featured are added which differs it from the existing system such as security.
Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.
2. INTRUDERS
• Many computer security incidents are caused
-by insiders
• Who could not be blocked by firewalls.
• So as a next level of defense
– we are using Intrusion detection system.
3. INTRUSION DETECTION SYSTEM
• intrusion detection system (IDS) is a device
• typically another separate computer, that
monitors
– activity to identify malicious or suspicious events.
• An IDS is a sensor
4. FUNCTIONS
• Monitoring users and system activity
• auditing system configuration for
vulnerabilities and misconfigurations
• assessing the integrity of critical system and
data files
• recognizing known attack patterns in system
activity
5. • identifying abnormal activity through
statistical analysis
• correcting system configuration errors
6. TYPES
• Signature-based intrusion detection systems:
– perform pattern-matching and
– report situations that match a pattern
corresponding to a known attack type.
• Heuristic intrusion detection
systems( anomaly based) build a
– detection looks for behavior that is out of the
ordinary.
7. • Intrusion detection devices can be
– network based or
– host based.
• network-based IDS is a
– stand-alone device attached to the network to monitor traffic
throughout that network
• host-based IDS runs on a single workstation or
client or host, to protect that one host.
8. Signature-Based Intrusion Detection
• The problem with signature-based detection is
the signatures themselves.
• An attacker will try to modify a basic attack in
such a way that it will not match the known
signature of that attack.
• signature-based IDSs cannot detect a new
attack for which a signature is not yet installed
in the database
9. Heuristic Intrusion Detection
• heuristic intrusion detection looks for
behavior that is out of the ordinary.
• Inference engine perform continuous analysis
of the system
• Raising an alert when systems dirtiness
increase the threshold.
• Inference engine works in 2 ways
– State based intrusion detection system.
– Model based intrusion detection system.
10. State based intrusion detection system:
• see the system going through changes of overall
state or configuration.
• They try to detect when the system moves to unsafe
state
Model based intrusion detection system:
• Map current activity into model of unacceptable
activity
• Raise an alarm when activity resembles the model.
11. Misuse intrusion detection:
• intrusion detection can work from a model of
known bad activity.
• All heuristic intrusion detection activity is
classified in one of three categories:
– good/benign,
– suspicious,
– unknown.
• Over time, specific kinds of actions can move
from one of these categories to another,
12. Stealth Mode
• An IDS is a network device .
• Any network device is potentially vulnerable
to network attacks.
• To counter those problems,:
• most IDSs run in stealth mode.
• an IDS has two network interfaces:
– one for the network being monitored
– to generate alerts
13. • The IDS uses the monitored interface as input
only
– it never sends packets out through that interface.
• If the IDS needs to generate an alert,
– it uses only the alarm interface on a completely
separate control network
14. Goals for Intrusion Detection Systems
• an IDS should be
– fast,
– simple,
– accurate,
– while at the same time being complete.
– It should detect all attacks with little performance
penalty
15. • An IDS could use some—or all—of the following design
approaches:
– filter on packet headers
– filter on packet content
– maintain connection state
– use complex, multipacket signatures
– use minimal number of signatures with maximum effect
– filter in real time, online
– hide its presence
– use optimal sliding time window size to match signatures
16. Responding to Alarms
• Whatever the type, an intrusion detection
system raises an alarm when it finds a match.
• The alarm can range from something modest,
such as writing a note in an audit log, to
something significant, such as paging the
system security administrator.
17. • responses fall into three major categories:
– monitor
– protect
– call a human
• Monitoring is appropriate for an attack of initial
impact.
• Perhaps the real goal is to watch the intruder,
• to see :
– what resources are being accessed or
– what attempted attacks are tried.
– This approach should be invisible to the attacker.
18. • Protecting can mean
– increasing access controls and
– even making a resource unavailable
• In contrast to monitoring, protecting may be very
visible to the attacker.
• calling a human allows individual discrimination.
• The IDS can take an initial defensive action
immediately while also generating an alert to a
human.
19. False Results
• Intrusion detection systems are not perfect.
– and mistakes are their biggest problem.
• 2 main false result:
– false positive-by raising an alarm for something that
is not really an attack
– false negative- not raising an alarm for a real attack.
• Too many false positives means the administrator
will be less confident of the IDS's warnings.
• But false negatives mean that real attacks are
passing the IDS without action.
20. IDS Strengths and Limitations
• Strength:
• IDSs detect an ever-growing number of
serious problems.
– And as we learn more about problems, we can
add their signatures to the IDS model.
– Thus, over time, IDSs continue to improve.
• becoming cheaper
• easier to administer.
21. • Limitation:
• avoiding an IDS is a first priority for successful
attackers.
• An IDS that is not well defended is useless.
• Similar IDS have identical vulnerabilities so
– there selection criteria will miss similar attack.
• IDS is sensitive
– Which is difficult to measure and adjust.
• An IDS does not run itself.
• General:
• IDS ARE EXCELLENT ADDITION TO NETWORK
SECURITY
22. SNORT
• It is a light weight open source network
– intrusion prevention
– Network intrusion detection system(NIDS)
• based on signature detection.
• It has real time alarming capacity.
23. • When an attack has occurred the alert tells us:
– Date and time the attack occurred.
– Source and destination IP address with port
number.
– Type of attack
– Priority
24. LOCATION:
• The snort have to be installed in those part of
the network that have to be protected.
• The snort can be distributed to different parts
of network infrastructure and can send alarm
to one central console.
• Snort network interface card(NIC) captures all
network traffic that goes by its NIC.
25. TOOLS:
• Snort Alert Monitor:
– Java based console.
– Will give a quick look at the Snort alert
– Can be configured to send e-mail when Snort alerts to
an attempted exploit on your network.
• Snortalog:
– It is a Perl based Snort log analyser.
– Allows to develop plaint text on HTML summery
reports and graph representation of top attack that
has been detected by Snort Sensor
26. • SnortFW:
– It analyses incoming Snort alerts and updates iptables
firewall to block the attacker.
• IDSCenter:
– It is an all-in-one centralized graphical utility for managing
• Snort
• Alerts
• Rules
• Configuration files
• Distributing updates
• Generate reports
• Email
• Auditable/visual alarm notification.
