The defensible architecture ensures that adversary activity on a network are visible and survivable, and it also ensures that defenders have actionable options. It helps to reconsider the four objectives of incident response, as discussed in Chapter 1, How Security Operations Are Changing, and Chapter 2, Incident Response A Key Capability in Security Operations.

Defensible architecture assists with these four objectives primarily through visibility, which assists with minimizing dwell time and understanding motivation and capability.

Finally, a defensible architecture must enable tactical options for the security team to actively thwart attackers. Tactical options consist...
