One of the reasons I started this blog was to share things I had encountered in the security and privacy world. I have done quite a bit of editorializing, but not too many of the quick and useful posts. I thought it might be helpful to post about five of my favorite reads and links on Fridays–unless I get too busy. So let’s start off with a few interesting links:
- PacketFence is a free and open source NAC system. I haven’t used it so I can’t vouch for it either way, but it’s nice to see a NAC in the free software world. NACs are good at preventing things like man-in-the-middle attacks, help you with asset control and help to keep the worm-of-the-day off your network when a contractor plugs in his laptop. Free software can also be a good way to meet a requirement even with limited or no budgets.
- Need a forensics tool? Maltego may fit the bill. It’s also free to use, but not free software in the sense that it doesn’t seem to have an OSI compatible license. Like PacketFence, there are also commercial support and versions available.
- Jamie Riden wrote a very nice piece on his/her response to an SSH attack. There are some nice recovery and lessons-learned aspects to the article. Another possible countermeasure would be the use of OSSEC along with its active response capabilities. This might have been able to prevent the compromise entirely.
- Would you like to have a log of all commands entered on a Cisco router? This is something that can be very useful for audit and compliance, as well as change management needs. This is a great one for PCI environments.
- The ‘nix mtr tool can be useful for troubleshooting network problems. The WinMTR does pretty much the same thing from a Windows host. It’s also free software.
That’s it for today. Have a wonderful weekend!
