561c9b6ba785c72de865c1bb5334b22bRSX is a Linux LKM which stops most buffer overflow attacks. It is a Runtime addressSpace eXtender providing on the fly code remapping of existing Linux binaries in order to implement non-executable stack as well as non-exec short/long heap areas. RSX targets common buffer-overflow problems preventing code execution in mapped data-only areas. Currently a 2.4.x version of the kernel module is available.

f31b863e65cf4e42820d482689e3046fStealth Syscall Redirection - This article describes a technique of redirecting system calls without modifying the sys call table (implemented in Linux). This can be used to evade intrusion detection systems that use the sys call table to register redirected or trojaned system calls. The basic premise behind this attack is to modify the old system call code to jump to the new system call, thus control is transferred to the replacement system call and the sys call table is left untouched.
917c0100d90f45ce4ca2c1e021da1f6dStMichael is a LKM that attempts to detect and divert attempts to install a kernel-module backdoor into a running linux system. This is done by monitoring the init_module and delete_module process for changes in the system call table. This is a experimental version, and a spin off from the Saint Jude Project.
5b4c791c22c5fa58c904835a96f0389eICMP Usage in Scanning v3.0 - This paper outlines what can be done with the ICMP protocol regarding scanning. Although it may seem harmless at first glance, this paper includes details on plain Host Detection techniques, Advanced Host Detection techniques, Inverse Mapping, Trace routing, OS fingerprinting methods with ICMP, and which ICMP traffic should be filtered on a Filtering Device.
f60a05e7802e4364c022896d78730665Georgi Guninski security advisory #46, 2001 - There is a buffer overflow in SunOS 5.8 x86 with $HOME and /usr/bin/mail leading to egid=mail. Includes exploit.

c5aff02f19eb6b0d6609b6f1a24ed2fbnabou is a Perl script which can be used to monitor changes to your system. It provides file integrity checking, and can also watch crontabs, suid files and user accounts for changes. It stores all data in standard dbm databases.
943b114cfbbbb3476bbecf7339401589The Linux Intrusion Detection System is a patch which enhances the kernel's security. When it's in effect, many system administration operations can be made impossible even for root. You can turn the security protection on or off on the fly and you can hide sensitive processes and prevent anyone from using ptrace or any other capability on your system. LIDS can also provide raw device and I/O access protection. LIDS FAQ available here.
