Snort on OpenWrt: Guarding the SOHO perimeter

Filed under
HowTos

If you're edgy about security for your SOHO LAN, you might want to consider moving your first line of defense out past your firewall. How about on your router, for example? If your router runs OpenWrt, you can do exactly that, by running Snort, the open source intrusion detection system (IDS) project that has become the most widely deployed IDS in the world. Throw in the firewall that comes out of the box with OpenWrt White Russian, and suddenly the perimeter seems a lot more secure.

Nicholas Thill -- known as Nico in the OpenWrt community -- maintains three separate packages for Snort in his repository of packages. They include a plain Jane version, without any support for logging to a database, and two database-specific packages: one for MySQL and one for PostgreSQL. All are based on the Snort release 2.3.3-1 and are considered to be in a testing state and not yet included in the official release.

For the sake of simplicity, I'll discuss the plain Jane installation in this article.

Full Story.

Black Hat 2014: Open Source Could Solve Medical Device Security

On the topic of source code liability, Greer suggests that eventually software developers, including medical device development companies, will be responsible for the trouble their software causes (or fails to prevent). I think it’s fair to say that it is impossible to guarantee a totally secure system. You cannot prove a negative statement after all. Given enough time, most systems can be breached. So where does this potential liability end? What if my company has sloppy coding standards, no code reviews, or I use a third-party software library that has a vulnerability? Should hacking be considered foreseeable misuse? Read more

Does government finally grok open source?

Yes, the government -- one U.S. federal government employee told me that government IT tends to be "stove-piped," with people "even working within the same building" not having much of a clue what their peers are doing, which is not exactly the open source way. That's changing. One way to see this shift is in government policies. For the U.S. federal government, there is now a "default to open," a dramatic reversal on long-standing practices of spending heavily with a core of proprietary technology vendors. Read more

The OS LinuX Desktop

Reader Oliver wanted to make his Linux Mint desktop look as much like a Mac as possible so others would find it easy to use. Given some of our previous Linux featured desktops, we know it wasn't tough, but the end-result still looks great. Here's how it's all set up. Read more

A Linux Desktop Designed for You

Desktop environments for Linux are not released ready-made. Behind each is a set of assumptions about what a desktop should be, and how users should interact with them. Increasingly, too, each environment has a history -- some of which are many years old. As you shop around for a desktop, these assumptions are worth taking note of. Often, they can reveal tendencies that you might not discover without several days of probing and working with the desktop. Read more
