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

Intrusion detection is a set of techniques and methods that are used to detect suspicious activity both at the network and host level. Intrusion detection systems fall into two basic categories: signature-based intrusion detection systems and anomaly detection systems. Intruders have signatures, like computer viruses, that can be detected using software. You try to find data packets that contain any known intrusion-related signatures or anomalies related to Internet protocols. Based upon a set of signatures and rules, the detection system is ab ....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

In the last three years, the networking revolution has finally come of age. More than ever before, we see that the Internet is changing computing as we know it. The possibilities and opportunities are limitless; unfortunately, so too are the risks and chances of malicious intrusions.

It is very important that the security mechanisms of a system are designed so as to prevent unauthorized access to system resources and data. However, completely preventing breaches of security appear, at present, unrealistic. We can, however, try to detect th ....etc
