Wireshark is the world’s foremost network protocol analyzer, and is the de facto (and often de jure) standard across many industries and educational institutions. Wireshark development thrives thanks to the contributions of networking experts across the globe. It is the continuation of a project that started in 1998. It started as Ethereal but was later re-branded as Wireshark due to trademark issues.

Linux systems, as many others in the Unix family, have a well-known lack of access control. There is a small granularity of discretionary access rights, only dividing between read, write and execute rights for file owner, and file group members. The RSBAC (Rule Set Based Access Control) framework solves this access control deficiency by giving detailed access control information, and you can implement almost any access control model in it, e.g. as a runtime registered kernel module. Also, there is a powerful logging system which makes intrusion attempts easily detectable.

The Firewall Tester (FTester) is a tool designed for testing firewalls filtering policies and Intrusion Detection System (IDS) capabilities. The tool consists of two perl scripts, a packet injector (ftest) and the listening sniffer (ftestd). The first script injects custom packets, defined in ftest.conf, with a signature in the data part while the sniffer listens for such marked packets. The scripts both write a log file which is in the same form for both scripts. A diff of the two produced files (ftest.log and ftestd.log) shows the packets that were unable to reach the sniffer due to filtering rules if these two scripts are ran on hosts placed on two different sides of a firewall. Stateful inspection firewalls are handled with the ‘connection spoofing’ option. A script called freport is also available for automatically parse the log files.

BlockSSHD is a Perl script based on BruteForceBlocker v1.2.3 that dynamically adds IPTables rules for Linux and pf firewall rules for BSD that block SSH brute force attacks. It can also detect ProFTPd login failures. BlockSSHD checks a log file you specify, for example /var/log/secure on a Red Hat, for SSH login failure messages. If it detects a failure message it records the source IP address and starts a counter. If messages continue to be detected from the same source IP address the counter is incremented for each message. When the counter reaches a user-specified threshold then the script will add a firewall rule blocking SSH connections from that source IP address. A user-specified time-out is also defined to trigger a reset of the counter. If the counter is incremented but has not yet reached the blocking threshold and a new login failure message arrives then BlockSSHD checks the time-out. If the last increment of the counter occurred earlier than the current time minus the time-out period then the counter is reset rather than incremented. The time-out defaults to 600 seconds (10 minutes).

PHPIDS (PHP-Intrusion Detection System) is a simple to use, well structured, fast and state-of-the-art security layer for your PHP based web application. The IDS neither strips, sanitizes nor filters any malicious input, it simply recognizes when an attacker tries to break your site and reacts in exactly the way you want it to. Based on a set of approved and heavily tested filter rules any attack is given a numerical impact rating which makes it easy to decide what kind of action should follow the hacking attempt. This could range from simple logging to sending out an emergency mail to the development team, displaying a warning message for the attacker or even ending the user’s session. PHPIDS enables you to see who’s attacking your site and how and all without the tedious trawling of logfiles or searching hacker forums for your domain.
