OpenBSD Not An Easy Nut to Crack

December 22, 2008 by Jacek Artymiak

A very interesting story over at /. Apparently the botnets that use brute force rather than smarts avoid (properly secured) OpenBSD. It's nice to see that the bad guys have so much respect for the Puffy.

Apple Removes The Anti-Virus Recommendation Note

December 8, 2008 by Jacek Artymiak

I noticed that Apple has withdrawn its Tech Note HT2550 in which it had recommended that Apple Mac OS X users install anti-virus software. This was immediately picked up by the sites that don't bother to check the facts (including big IT portals). The damage control seems to have worked and now hardly anybody is discussing this subject as the world gets ready for the winter holidays season.

Congratulations, Richard!

(via SecurityFocus) Microsoft has released more information related in the MS08-067 bulletin. If you haven't patched, your system may become a host to the Conficker.A and IRCbot.BH and possibly -- DOWNAD.A and NETWORM.C. You don't want that. Don't wait, patch up.

Why Do We Need to Secure Our Networks?

November 26, 2008 by Jacek Artymiak

I published this in 2003, in the second edition of "Building Firewalls with OpenBSD and PF". It's still relevant.

Will Hollywood Be Making Movies About BotHunter?

November 26, 2008 by Jacek Artymiak

A very interesting piece of news found over at SecurityFocus.com. SRI International released a free anti-botnet tool called BotHunter. It will monitor networks for botnet activity and notify the network administrator, if it finds anything suspicious. It's a good thing that something is being done to help the administrators.
