Samhain is a file system integrity checker that can be used as a client/server application for centralized monitoring of networked hosts. Databases and configuration files can be stored on the server. Databases, logs, and config files can be signed for tamper resistance. In addition to forwarding reports to the log server via authenticated TCP/IP connections, several other logging facilities (e-mail, console, and syslog) are available. Tested on Linux, AIX, HP-UX, Unixware, Sun and Solaris.

Publimark is a command line tool to secretly embed text in an audio file. Like cryptography, it uses a pair of keys: the public one can be shared, whereas the private one must be kept secret. Anybody can send a steganographic message, but only the private key owner will be able read it. Marked audio files are still playable.

Tvark is a network monitoring tool with a GUI front-end and is tied to a MySQL database. The GUI provides a view of traffic activity that can be seen from the machine/interface that Tvark is run on. What the end user sees is a list of source nodes on the left, destination nodes on the right, and lines drawn, left to right, showing traffic flow. Tvark runs in realtime, meaning the traffic is shown roughly as it happens with a small delay between it and the display being created.

Nmap Parser is a Perl module that simplifies the process of developing scripts and collecting information from the XML nmap scan data, which can be obtained by using nmap's -oX switch or from the file handle of a pipe to an nmap process. It uses the XML twig library for parsing, and supports filters.

Wflogs is a firewall log analysis tool. It can be used to produce a log summary report in plain text, HTML, and XML, or to monitor firewalling logs in real-time. For now, netfilter, ipchains, ipfilter, cisco_pix, cisco_ios, and snort input formats are supported. It is particularly fast when asynchronous DNS resolution is enabled. The goal of the WallFire project is to build a very general and modular firewalling application based on Netfilter or any kind of low-level framework. Wflogs is part of the WallFire project, but can be used independently.

TinyCA is a simple GUI written in Perl-Gtk to manage a small certification authority. It works as a frontend to OpenSSL. TinyCA lets you manage x509 certificates. It is possible to export data in PEM or DER format for use with servers, as PKCS#12 for use with clients, or as S/MIME certificates for use with email programs. It is also possible to import your own PKCS#10 requests and generate certificates from them. It also lets you create and manage SubCAs for more complex setups. The most important certificate extensions can be configured with the graphical frontend. English and German translations are included.

mod_ssl provides provides strong cryptography for the Apache 1.3 webserver via the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1). It is based on the SSL/TLS toolkit OpenSSL and supports all SSL/TLS related functionality, including RSA and DSA/DH cipher support, X.509 CRL checking, etc. Additionally it provides special Apache related facilities like DBM and shared memory based inter-process SSL session caching. per-URL SSL session renegotiations, DSO support, etc.

httprint is a web server fingerprinting tool. It relies on web server characteristics to accurately identify web servers, despite the fact that they may have been obfuscated by changing the server banner strings, or by plug-ins such as mod_security or servermask. httprint can also be used to detect web enabled devices which do not have a server banner string, such as wireless access points, routers, switches, cable modems, etc. httprint uses text signature strings and it is very easy to add signatures to the signature database. httprint can import web servers from nmap network scans, if they are saved in XML format. The current version adds the ability to save reports in CSV and XML formats, and features a completely new method of scoring by confidence ratings to minimize false positives. This version is the Windows release.
