This is a very simple snort rule object. It was developed to allow for scripted dynamic rule creation. Ideally you could dynamically take a list of bad hosts and build an array of snort rule objects from that list. Then write that list using the string() method to a snort rules file.

Module::Signature adds cryptographic authentications to CPAN distributions, via the special SIGNATURE file. If you are a module user, all you have to do is to remember running "cpansign -v" (or just "cpansign") before issuing "perl Makefile.PL" or "perl Build.PL"; that will ensure the distribution has not been tampered with. For module authors, you'd want to add the SIGNATURE file to your MANIFEST, then type "cpansign -s" before making a distribution.

dsniff is a collection of tools for network auditing and penetration testing. dsniff, filesnarf, mailsnarf, msgsnarf, urlsnarf, and webspy passively monitor a network for interesting data (passwords, e-mail, files, etc.). arpspoof, dnsspoof, and macof facilitate the interception of network traffic normally unavailable to an attacker (e.g, due to layer-2 switching). sshmitm and webmitm implement active monkey-in-the-middle attacks against redirected SSH and HTTPS sessions by exploiting weak bindings in ad-hoc PKI.

Belier allows opening a shell or executing a command on a remote computer through a SSH connection. The main feature of Belier is its ability to cross several intermediate computers before realizing the job.

This is a PHP library providing a wrapper to Colin Percival's scrypt implementation. Scrypt is a key derivation function designed to be far more secure against hardware brute-force attacks than alternative functions such as PBKDF2 or bcrypt.

PHP bindings to the libssh2 library which provide access to resources (shell, remote exec, tunneling, file transfer) on a remote machine using a secure cryptographic transport.

BruteForceBlocker is a perl script, that works along with pf - OpenBSD's firewall (Which is also available on FreeBSD since version 5.2 is out). It's main purpose is to block SSH bruteforce attacks via firewall. When this script is running, it checks sshd logs from syslog and looks for Failed Login attempts - mostly some annoying script attacks, and counts number of such attempts. When given IP reaches configured limit of fails, script puts this IP to the pf's table and blocks any further traffic to the that box from given IP (This also depends on configuration done in pf.conf).

This is a PAM module which allows authentication against alternate passwd files.

A PAM module that allows you to require a special group or user to access a service.

This PAM service module allows PAM-enabled applications to check if the target user is in some arbitrary plaintext list. Similar to module pam_ftpusers from the FreeBSD Project and is based on it's code.
