Linux Enhancing kernel security with grsecurity
Post date: November 25, 2005, 16:11 Category: Security Views: 74
Tutorial quote: Is your server as secure as it could be? Sure, you use a firewall, mandate strong passwords, and patch regularly. You even take a proactive approach by performing security audits with tools such as nmap and Nessus. Yet you may still be vulnerable to zero-day exploits and privilege escalation attacks. If these possibilities keep you awake at night, you're not alone. The sleepless folks with the grsecurity project have developed an easy-to-use set of security enhancements to help put your fears to rest.

Unix+clones Easy Automated Snapshot-Style Backups with Linux and Rsync
Post date: January 31, 2006, 19:01 Category: Software Views: 27
Tutorial quote: This document describes a method for generating automatic rotating "snapshot"-style backups on a Unix-based system, with specific examples drawn from the author's GNU/Linux experience. Snapshot backups are a feature of some high-end industrial file servers; they create the illusion of multiple, full backups per day without the space or processing overhead. All of the snapshots are read-only, and are accessible directly by users as special system directories. It is often possible to store several hours, days, and even weeks' worth of snapshots with slightly more than 2x storage. This method, while not as space-efficient as some of the proprietary technologies (which, using special copy-on-write filesystems, can operate on slightly more than 1x storage), makes use of only standard file utilities and the common rsync program, which is installed by default on most Linux distributions. Properly configured, the method can also protect against hard disk failure, root compromises, or even back up a network of heterogeneous desktops automatically.
Linux Linux stateful firewall design
Post date: April 12, 2005, 13:04 Category: Network Views: 40
Tutorial quote: This tutorial shows you how to use netfilter to set up a powerful Linux stateful firewall. All you need is an existing Linux system that's currently using a Linux 2.4.x or 2.6.x kernel. A laptop, workstation, router or server with at a Linux 2.4.x or 2.6.x kernel will do. You should be reasonably familiar with standard network terminology like IP addresses, source and destination port numbers, TCP, UDP and ICMP, etc. By the end of the tutorial, you'll understand how Linux stateful firewalls are put together and you'll have several example configurations to use in your own projects.
