Kojoney ( is a niche honeypot program for creating a secure shell (ssh) honeypot.  While it’s use may see limited since it is focusing purely on ssh, many enterprise may prefer simple configuration for the few applications they may have exposed to the Internet (mail, web, and ssh).

The user poustchi over at HotoForge has published an article on how to quickly get Kojoney up and running quickly on Cent OS 5.5, although the instructions are solid enough to get Kojoney up and running on most Linux and Unix platforms:

Securing Linux: New Release of Devil-Linux

Rmccarty Ronald McCarty Profile: Rmccarty

Engine Solutions has released version 1.4RC6 of Devil-Linux.  For those not familiar with Devil-Linux, it is a small secure distribution that runs from a CD-ROM or USB thumb drive.

The release fixes issues found since the last release candidate, which makes it likely worth the upgrade; however, it also includes some updates such as  MailScanner version 4.8.1.  This version of MailScanner is the latest release and alone makes the distribution worth considering for new users.  MailScanner is a freely available mail security and anti-virus gateway.  It is made for placing at your Internet gateway and checking all email coming into a company’s mail system.

For more information on Devil-Linux see and for MailScanner look here:

Welcome to Secure Penguin

Rmccarty Ronald McCarty Profile: Rmccarty

Welcome to Secure Penguin!  I’ll be covering information security from a Linux perspective.  The topics (good and bad) may be slanted towards Red Hat, as I am exposed to quite  a bit of it in the enterprise space; however, the goal is to cover Linux in general.

If you have any comments or suggestions for topics, please drop me a line.
