Ettercap is a network sniffer/interceptor/logger for ethernet LANs. It supports active and passive dissection of many protocols (even ciphered ones, like SSH and HTTPS). Data injection in an established connection and filtering on the fly is also ... [More] possible, keeping the connection synchronized. Many sniffing modes were implemented to give you a powerful and complete sniffing suite. Plugins are supported. It has the ability to check whether you are in a switched LAN or not, and to use OS fingerprints (active or passive) to let you know the geometry of the LAN. [Less]

John the Ripper is a fast password cracker, currently available for many flavors of Unix (11 are officially supported, not counting different architectures), Windows, DOS, BeOS, and OpenVMS. Its primary purpose is to detect weak Unix passwords. ... [More] Besides several crypt(3) password hash types most commonly found on various Unix flavors, supported out of the box are Kerberos AFS and Windows NT/2000/XP/2003 LM hashes, plus several more with contributed patches.

Prelude is an Hybrid IDS framework, that is, it is a product that enable all available security application, be it opensource or proprietary, to report to a centralized system. In order to achieve this task, Prelude relies on the IDMEF (Intrusion ... [More] Detection Message Exchange Format) IETF standard, that enables different kinds of sensors to generate events using an unified language. Prelude benefits from its ability to find traces of malicious activity from different sensors (Snort, honeyd, Nessus Vulnerability Scanner, Samhain, over 30 types of systems logs, and many others) in order to better verify an attack and in the end to perform automatic correlation between the various events. Prelude is commited to providing an Hybrid IDS that offers the ability to unify currently available tools. [Less]

sshproxy is a pure python implementation of an ssh authenticating proxy. It allows users to connect to remote sites without having to know the password or key of the remote sites. ACL rules can be set up to allow or deny users based on ... [More] different parameters like their IP address or the time of the day. Access attempts are logged via syslog, and an enhanced "action log" system is under development. The client is the standard ssh client. [Less]

ITVal is an open source utility for testing, and debugging iptables firewall policies. It can detect many different kinds of errors, such as typos, out-of-order rules, faulty understanding of the firewall, or poor assumptions about the policy logic. ... [More] ITVal can also generate a "policy map" that illustrates how the firewall treats various groups of hosts on the network. This grouping is automatically calculated from the policy and can make it very easy to spot anomalies in the policy. Current development on ITVal focuses on ways to partially automate repair of the policy. [Less]
