C5 (Germany) C5-COS-03: Monitoring of connections in the Cloud Service Provider's network

Separate trusted from untrusted networks into risk-based security zones, configure physical and virtual networks to restrict and monitor those connections, reassess that design at least annually, and periodically re-justify every service, port and protocol in use.

Other controls in C5: Communication Security

You are reading one control. How much of C5 (Germany) have you already done?

C5 (Germany) C5-COS-03 is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of C5 (Germany) your existing evidence covers. Hold Cloud Security Alliance Cloud Controls Matrix (CCM) v4.0.1 and 95 of 121 C5 (Germany) controls already carry evidence.

Each report names every control your existing framework evidences, every one it does not, the reasoning behind each claim, and the claims that were argued against and rejected. 0 were rejected on the Cloud Security Alliance Cloud Controls Matrix (CCM) v4.0.1 pair alone.
