VMware would like to announce the availability of the final release of the vSphere 4.1 Security Hardening Guide. The Introduction section describes the scope, structure, recommendation levels, and other aspects of the guide in more detail. Please read this section first before diving into the rest of the guide, as it provides important context.
Although this version of the guide can be considered as "final" and appropriate for use in production environments, we recognize that there is always room for improvement. We will continue to welcome comments and corrections on this guide, and we will publish updated versions of the guide from time to time as feedback is accumulated. This feedback of course will also be incorporated into the hardening guide for future releases of vSphere.
