Automated Detection of Stealthy Portscans (Network Intrusion Detection System)

Portscanning is a common activity of considerable importance. It is often used by computer attackers to characterize hosts or networks which they are considering hostile activity against. Thus it is useful for system administrators and other network defenders to detect portscans as possible preliminaries to a more serious attack.

There are two general purposes that an attacker might have in conducting a portscan: a primary one, and a secondary one. The primary ....etc

With hacker attacks against well-known businesses and organizations on the rise, network security has made headlines. Of course, there are many attacks that do not make headlines and are not reported due to a loss of credibility or embarrassment. Then there are the attacks that are not even detected. The Defence Information Services Agency (DISA) states that up to 98% of attacks go unnoticed. These revelations have caused many businesses to rethink or to start thinking about the security of their own networks. For some organizations security ha ....etc

Abstract
At the heart of most computer systems is a file system. The file system contains user data, executable programs, configuration and authorization information, and (usually) the base executable version of the operating system itself. The ability to monitor file systems for unauthorized or unexpected changes gives system administrators valuable data for protecting and maintaining their systems. However r, in environments of many networked heterogeneous platforms with different policies and software, the task of monitoring changes become ....etc

Intrusion Prevention and Automated Response in Sachet Intrusion Detection System

An Intrusion Detection System (IDS) monitors computer systems and network traffic, analyzes the traffic to identify possible security breaches, and raises alerts. It is difficult for human users to analyze the alerts and take swift appropriate actions which gives the attacker enough opportunity to continue to carry out further attacks. It is therefore important to take some automated actions to stop the attack. Unlike intrusion detection system, which pas ....etc

ABSTRACT

The Mobile Agent based Intrusion Detection System (MINDS) deploy mobile agents from a central control node to target machines, at pre specified time intervals. Mobile agents are objects that can migrate from node to node in a heterogeneous network, at times and to places of their own choosing. The state of the object is saved, transported to the new node, and restored, allowing the object to continue where it left off. These agents check for changes in the monitored files using md5checksum algorithm. Any changes fou ....etc

ABSTRACT
This seminar report describes how you can protect your system from Intrusion, which is the method of Intrusion prevention and Intrusion detection. The underlying premise of our Intrusion detection system is to describe attack as instance of ontology and its first ....etc
