VMware recently released a free tool that checks your VMware ESX/ESXi servers against a set of guidelines specified in the VMware vSphere 4.1 Hardening Guide.
Here is how it works:
- The Compliance Checker runs an assessment on ESX/ESXi hosts managed by vCenter
- The assessment is based on a predefined subset of 29 of the vSphere 4.1 Security Hardening Guide rules and is run against the first 5 ESX/ESXi hosts found on the target vCenter
- The results for each host include the rules, the rule descriptions, and the success or failure of each rule
