C5 (Germany) C5-COS-01: Technical safeguards

Deploy risk-derived technical controls that promptly detect and respond to irregular inbound or outbound traffic patterns and distributed denial of service attacks, feeding their output into a SIEM so correlated events can trigger countermeasures.

Other controls in C5: Communication Security

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

C5 (Germany) C5-COS-01 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.
