Never A Better Time To Baseline

If you’re preparing to install Windows 7 or Windows Server 2008 R2 Service Pack 1, now would be a good time to give Microsoft’s Attack Surface Analyzer a spin. ASA takes a baseline snapshot of your system state and then lets you take another snapshot after any configuration change or product installation and displays the changes to a number of key elements of the Windows attack surface, including analysis of changed or newly added files, registry keys, services, ActiveX Controls, listening ports, access control lists and other parameters.

Ideally, you’d take your baseline after a fresh install of your workstation or server from known, good media/images and after your own base configuration changes.

This would also be a good thing to do when building your base VM images so you can then validate their state as you duplicate and modify VDIs.

The installation of a Service Pack is a pretty radical change to your environment. If you run ASA prior to the SP install you can see if there are any significant changes to your system’s security profile after the bundle of patches and hotfixes are put down. You could also use the SP1 event to baseline post-install, provided you’ve done as thorough of a malware & rootkit sweep as can be done (you still cannot truly trust the results).

It may take some discipline to run ASA regularly on your personal systems every time you update software or drivers. IT shops should have an easier time scripting ASA during system deployments as well as application code updates. In either scenario, this free tool from Microsoft should help make you a more informed user and also aid you in building and maintaining more secure systems.

Windows

  • Windows 7/2008 SP1 looms large. OEMs, VLCs & MSDN/TechNet subscribers get it on February 16th and the rest of the masses can give it a go on February 22nd. It looks like it has a decidedly enterprise-y focus, but one can hope it continues Microsoft on the path to robust desktop & server experiences :: Announcing The Availability of Windows 7 and Windows Server R2 SP1 [Microsoft]
  • Autoruns – the ability to automatically perform tasks when certain devices are made available to Window systems (e.g. USB sticks) – are a boon to malware writers. While Microsoft has somewhat mitigated the threat they pose in more modern versions of their operating systems, it can be tricky to make older systems safe. With the latest round of Patch Tuesday updates, they included a way to disable Autoruns in older systems. W00t! Microsoft Update Offers an Easier Way to Turn off Autoruns [PC World]
