Snort

Snort is an open source network intrusion prevention system, capable of performing real-time traffic analysis and packet logging on IP networks. It can perform protocol analysis, content searching/matching and can be used to detect a variety of attacks and probes, such as buffer overflows, stealth port scans, CGI attacks, SMB probes, OS fingerprinting attempts, and much more.

Snort uses a flexible rules language to describe traffic that it should collect or pass, as well as a detection engine that utilizes a modular plugin architecture. Snort has a real-time alerting capability as well, incorporating alerting mechanisms for syslog, a user specified file, a UNIX socket, or WinPopup messages to Windows clients using Samba’s smbclient.
Snort has three primary uses. It can be used as a straight packet sniffer like tcpdump(1), a packet logger (useful for network traffic debugging, etc), or as a full blown network intrusion prevention system.





Burp intruder

Burp intruder is a tool to facilitate automated attacks against web-enabled applications. It is not a point-and-click tool: using burp intruder effectively requires a detailed knowledge of the target application, and an understanding of the HTTP protocol.

Burp intruder is highly configurable and can be used to automate a wide range of attacks against applications, including testing for common web application vulnerabilities such as SQL injection, cross-site scripting, buffer overflows and directory traversal; brute force attacks against authentication schemes; enumeration; parameter manipulation; trawling for hidden content and functionality; session token sequencing and session hijacking; data mining; concurrency attacks; and application-layer denial-of-service attacks.
