Port Knocking

Post date: April 16, 2005, 10:04 Category: Network Views: 3008 Comments
Tutorial quote: Firewall administrators are challenged to balance flexibility and security when designing a comprehensive rule set. A firewall should provide protection against malfeasants, while allowing trusted users to connect. Unfortunately, it is not always possible to filter out the bad guys, because filtering on the basis of IP addresses and ports does not distinguish connecting users. Bad guys can and do come from trusted IP addresses. Open ports remain a necessary vulnerability: they allow connections to applications but also may turn into open doors for attack. This article presents a new security system, termed port knocking, in which trusted users manipulate firewall rules by transmitting information across closed ports.

X Window Manager Benchmarks (E17 on Top)

Post date: June 9, 2005, 14:06 Category: Benchmarks Views: 3778 Comments
Tutorial quote: I've been focusing on some stability issues of late in E17, but more importantly - speed. I've been doing a little profiling and shaving off cycles where I can find readily optimizable code. I have E17 starting in 0.52 seconds (from execute to usable desktop). Considering that involves loading and rendering and scaling a complex multi-leayered desktop background, loading multiple useful modules (pager, ibar, start, dropshadow, cpufreq handler, clock, etc.), then that's not too bad.

Now I'm a numbers man. I like numbers. I don't like vague "it's faster than X" or "that's slower than this" statements without numbers to back it up. I also like to play fair. Also given there are no "performance suites" i know of that measure window manager performance, I wrote a quick and dirty one.

Intrusion Detection For PHP Applications With PHPIDS

Post date: June 24, 2008, 14:06 Category: Security Views: 4466 Comments
Tutorial quote: This tutorial explains how to set up PHPIDS on a web server with Apache2 and PHP5. 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.

Lightweight Web Serving with thttpd

Post date: December 1, 2005, 00:12 Category: Software Views: 7801 Comments
Tutorial quote: The Apache HTTP Server is the most popular web server due to its functionality, stability, and maturity. However, this does not make it suitable for all uses: slow machines and embedded systems may have serious problems running it because of its size. Here is where lightweight HTTP servers come into play, as their low-memory footprints deliver decent results without having to swap data back to disk.

Similarly, these small HTTP servers are suitable to serve static content efficiently so as to allow Apache, mod_perl, mod_python, or even servlet containers to handle dynamic requests without tying up memory-hungry children to serve small images. In other words, these applications can serve as a complement to your existing full-featured web server, not as a replacement.

One of these servers is thttpd, a simple, small, portable, fast, and secure HTTP server. Among its features are support for the HTTP/1.1 standard, CGIs, virtual hosts, and IPv6. This article shows how to install and configure this software under NetBSD. I chose NetBSD not only because it is my preferred OS, but also because it has the ability to run on the most disparate old hardware, where thttpd shows its strengths. I had a Macintosh Performa 630 (a 68LC040 chip at 33MHz) running NetBSD/mac68k 2.0 with thttpd on top of it, serving pages to my home network nicely.
