Richard Bejtlich
@[email protected]I was a captain in the United States Air Force who formally trained as an intelligence officer. I later worked in information warfare. I promoted the concept that "prevention eventually fails" in my first book (2004) and developed tactics, operations, and strategy to detect and respond to nation-state and criminal computer intrusions. I wrote about cybersecurity from 2001 to 2021. I created the GE-CIRT and was Mandiant's first CISO. I currently advocate #NetworkSecurityMonitoring for @corelight. My latest books are here #ad https://amzn.to/3B2AcMc
