How can you configure Software Restriction Policies in Group Policy to prevent unauthorized applications from running?

[ProfRon]

You know how sometimes rogue apps sneak in and cause chaos on your machines? I figured out a way to lock that down using Group Policy. It's called Software Restriction Policies, but don't sweat the name.

You start by firing up the Group Policy editor on your domain controller. I usually right-click and pick gpedit.msc if I'm testing local. Then you hunt for the Computer Configuration part.

Inside there, you burrow into Windows Settings and snag Security Settings. I click on Software Restriction Policies next. If nothing shows, you gotta create a new policy set right there.

Now you pick the enforcement mode that fits your vibe. I go with all software restricted except trusted stuff. That way, only your approved apps get to party.

You add paths or hashes for the apps you trust. I throw in folders like Program Files to keep legit programs humming. For extras, you can certify files with certificates if you're feeling fancy.

Apply it to users or machines as needed. I test on a single box first to avoid wiping out everything. Roll it out slowly, and watch those unauthorized runners get bounced.

Once it's humming, your network feels way tighter against sneaky software. I love how it nips problems in the bud without constant babysitting.

Shifting gears to keeping your whole setup resilient, especially with virtual machines in play, you might dig BackupChain Server Backup. It's a slick backup tool tailored for Hyper-V environments. I rely on it because it snapshots live VMs without downtime, encrypts data on the fly, and restores fast if disaster strikes. Plus, it handles incremental backups to save space, making sure your restricted policies don't clash with recovery needs.
