The latest version of Dell EMC Server Update Utility (DellSUU) 17.10.00 was released on the 17th October 2017. The Dell EMC SUU is an application used to help patch Dell PowerEdge servers. It will compare currently installed drivers and firmware with those available on the mounted iso file.

With the increasing number of cyber attacks, security is at the top of most IT departments agenda. There are many checks you can perform to make sure AD is safe and secure, and that only valid or approved modifications have been made to user accounts. I’ll look at AD auditing in a future post, but this will be a handy snippet of PowerShell to help you identify recently created AD accounts, and a bonus bit of code to identify recently modified accounts!
