We're sharing a special bonus episode in your feed this week, from the CyberWire's CSO Perspectives podcast hosted by Rick Howard.  This episode, Cybersecurity First Principles: Intrusion Kill Chains, Rick talks about why intrusion kill chains are the perfect companion strategy to the passive zero trust strategy he talked about last week. The key takeaway here is that we should be trying to defeat the humans behind the campaigns collectively, not simply the tools they use independently with no context about what they are trying to accomplish.
