I spoke with Exabeam‘s Chief Security Strategist, Steve Moore, about post-breach cleanup, specifically related to the healthcare industry. Steve and I discussed why the healthcare industry is a prime target for hackers, what steps to take after a breach, and some preventative steps. Post-breach cleanup can seem daunting and as we say in the podcast, “How do you know what’s clean?” The problem with breaches is that you don’t know what’s clean nor do you always know to what depth the breach has penetrated. I think it’s best to wipe a system clean and reimage it from scratch rather than trying to poke and prod your way through the maze of malware, backdoors, fake user accounts, and other persistent threats that remain after a breach. Opinions differ in this area but the peace of mind that comes with installing fresh is far more valuable and often less time-consuming that individually examining thousands of files, filesystems, and backups for elusive infections.

Preston and I interviewed Ryan Benson, Senior Threat Researcher at Exabeam about Security Information and Event Management (SIEM) software. We discussed what SIEM software is, what it does for a company, how it protects your network, and how to evaluate a SIEM suite.
Preston and I also agree that a SIEM suite should offer more than simple log aggregation and log scraping. There are less expensive and less cumbersome tools that can handle that functionality if that’s all you need. We also agree that SIEM companies need to bake some intelligence into their products that allow them to be automated, to respond automatically to threats, and to include advanced analytics so that you can optionally find out what’s going on and going wrong on your network.
Ryan gives us some insight into what’s going on in SIEM software and why you should care. Before you purchase a SIEM solution, take his advice offered in the podcast.
