Linux Security Auditing
Many people consider that by running linux, you're in a more secure environment than if you're running other operating systems. I take the view that the amount of effort that's expended in attacking a particular system is directly related to the potential return. As linux is both relatively uncommon, and comes in many different flavours, it's a hard target - so why bother? However, this 'security through obscurity' approach becomes less and less valid with the increasing popularity of linux. We feel that it's far better to take security seriously, than to be caught napping.
It is especially important to ensure that your internet facing services: web, mail, ssh etc are kept up to date, as well as any supporting software ( both as the base level and applications - eg PHP and any relevant CMSes you are using ) that you have installed. Some systems ( eg drupal ) tell you when they need updating, but the majority don't. We keep ourselves well informed on these security issues, so can quiclky identify and rectify any potential problems.
We can offer an audit of existing platforms, reporting and making recommendations. If you wish we can take it further, we will happily attack your servers to see how they hold up. Just give us permission first!
