Let's face it: it only takes one security stumble to wipe out PC usability for the entire employee base. Conducting an audit is the best way to assess and address security holes without paying for an overpriced consultant or a costly vendor solution. Now is the time to audit desktop application and workstation security.
The purpose of any security audit is to compare current practices against best practices. Through this comparison, an audit seeks out gaps (whether in policy, procedure, or technology) in your current practices, and then analyzes them to provide baseline recommendations for improving security levels.
