On Tuesday August 14th, Intel Released their news on the latest vulnerability L1 Terminal Fault (L1TF) or ForeShadow. In response to this VMware released vSphere patches to address the issues. Since then I have seen quite a few threads come up and thought i would address them from a patching perspective.
So going though v7, v8 and v9 of the certificate guides I continued to have some issues getting the certificate to work and the steps never included ways to add subject alternative names. Upon further research I have identified a good step by step to replace the trend micro DSM certificate and include subject alternative names using a Microsoft certificate authority.
