Welcome back to IT Pro Tuesday!

In the latest episode of the Security Swarm Podcast: “Questionable Methods for Protecting Backups from Ransomware,” we explore some historical methods devised by the security community to safeguard backups against ransomware such as air gapping, removable media, and application whitelisting. But here’s the twist: we’re approaching these protective measures from the mindset of a relentless threat actor… someone who’s determined to breach your defenses and make your backups their own.

We’re also looking for your favorite tips and tools we can share with the community… those that help you do your job better and more easily. Please reply or leave a comment with your suggestions, and we’ll be featuring them in the coming weeks.
