VMware would like to announce the availability of a public draft for the vSphere 4.1 Security Hardening Guide. This guide is an incremental update to the vSphere 4.0 Security Hardening Guide based on new and changed features of vSphere. As with the earlier guide, this guide follows a standardized structure and format, which is explained in detail in this posting.
You can find the draft at the following link: http://communities.vmware.com/docs/DOC-14548. This draft will remain posted for comments until approximately the end of February 2011. We welcome your feedback on this draft; please provide it in the comments section for that document.
