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 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.
EverCrack is a cryptanalysis engine. The overall design goal is to systematically break down complex ciphers into their simplex components for cryptanalysis (by the kernel). The kernel consists of an algebraic design (comparison and reduction) for breaking uniliteral, monoalphabetic ciphers instantaneously. Currently, it can break a 4000-word cipher in milliseconds. EverCrack currently has multi-language support for the user interface and cracking encryption in other language dictionaries (English, German, French, Spanish, Italian, Swedish, Dutch, and Portuguese).
FTimes is a system baselining and evidence collection tool. Its primary purpose is to gather and/or develop topographical information and attributes about specified directories and files in a manner conducive to intrusion and forensic analysis. It was designed to support the following initiatives: content integrity monitoring, incident response, intrusion analysis, and computer forensics.
Firekeeper is an intrusion detection and prevention system for Firefox. It is able to detect, block and warn the user about malicious sites. Firekeeper uses flexible rules similar to Snort ones to describe browser-based attack attempts. Rules can also be used to effectively filter different kinds of unwanted content.
Firewall Builder for PIX hides the complexity of PIX command line interface and automatically configures options and parameters that usually make manual configuration a real chore. With this module, the same workstation running Firewall Builder can create and manage security policy on Cisco PIX or FWSM firewalls, as well as on firewalls built with iptables, OpenBSD pf, or ipfilter.
FlexiCA is a certification authority tool. It is implemented using Java and the Eclipse Rich Client Platform. FlexiCA is extensible and supports RSA, DSA, and Elliptic Curve cryptography out of the box. Other crypto-systems may be added easily, if ASN.1 structures for encoding are available. All cryptographic functions are provided by FlexiProvider.
