8 Blended Threats Require Blended Protection Conficker was the first, but not the the endpoint: Start with the basics (e.g. passwd policies, patch management, the endpoint: Continuous policy the network: Confirm policy compliance prior to access; access tied to profile (managed vs. unmanaged) 8

9 Meeting Policy Enforcement Challenges Mobility now on network, now off Roaming laptops, mobile devices Consequences: maintenance challenges; increased exposure risk; loss of visibility/control Security approach: Location-aware, continuous protection policies Different user profiles Managed (employee) vs. unmanaged (guest) Consequences: too restrictive = productivity obstacles; too permissive = exposure risks Security approach: Profile-aware access policies Comprehensive security requires continuous protection regardless of computing context or network connection. 9
