Chkrootkit Portsentry Howto

Post date: April 15, 2005, 23:04 Category: Security Views: 2789 Comments
Tutorial quote: This document describes how to install chkrootkit and portsentry. It should work (maybe with slight changes concerning paths etc.) on all *nix operating systems.

Chkrootkit "is a tool to locally check for signs of a rootkit" (from http://www.chkrootkit.org).

"The Sentry tools provide host-level security services for the Unix platform. PortSentry, Logcheck/LogSentry, and HostSentry protect against portscans, automate log file auditing, and detect suspicious login activity on a continuous basis" (from http://sourceforge.net/projects/sentrytools/).

This howto is meant as a practical guide.

LDAP Authentication In Linux

Post date: August 26, 2006, 06:08 Category: Security Views: 5434 Comments
Tutorial quote: This howto will show you howto store your users in LDAP and authenticate some of the services against it. I will not show howto install particular packages, as it is distribution/system dependant. I will focus on "pure" configuration of all componenets needed to have LDAP authentication/storage of users. The howto assumes somehow, that you are migrating from a regular passwd/shadow authentication, but it is also suitable for people who do it from scratch.

How to scan your Linux-Distro for Root Kits

Post date: May 19, 2006, 18:05 Category: Security Views: 3197 Comments
Tutorial quote: Do you suspect that you have a compromised system ?
Check now for root kits that the intruder may have installed !!!

So... What in the hell is a root kit ???
A root kit is a collection of programs that intruders often install after they have compromised the root account of a system.
These programs will help the intruders clean up their tracks, as well as provide access back into the system.
Root kits will sometimes leave processes running so that the intruder can come back easily and without the system administrator's knowledge !

Solution....
Scripts like chkrootkit will do the job for you automatically.
