7MS #551: Interview with Matt Warner of Blumira
Today we welcome our pal Matthew Warner (CTO and co-founder of Blumira) back to the show for a third time (his first appearance was #507 and second was #529).
I complained to Matt about how so many SIEM/SOC solutions don't catch early warning signs of evil things lurking in customer networks. Specifically, I whined about 7 specific, oft-missed attacks like port scanning, Kerberoasting, ASREPRoasting, password spraying and more. (Shameless self-promotion opportunity: I will be discussing these attacks on an upcoming livestream on December 29).
Matt dives into each of these attacks and shares some fantastic insights into what they look like from a defensive perspective, and also offers practical strategies and tools for detecting them!
