Recently in Computerworld, a security manager reported on a frightening realization about the user account he was using in his unnamed vulnerability scanner. > The product I use relies on a user account to connect to our Microsoft Windows servers and workstations to check them for vulnerable versions of software, and that user account had never been configured properly. As a result, the scanner has been blind to a lot of vulnerabilities. For more details, see

Scanning time machine: Reporting on a historical scan

In network security, the questions are urgent. Are we protected against malware? Do we have protocols in place to prevent a hacker from breaking in? Sometimes, however, you need to look back in time and see what the status was in the past. If you have been tracking a vulnerability and it finally goes away, you might want to check the information in a past scan and compare it to changes in your environment. Another reason you might want to report on a historical scan is an audit. If you are re
