TVM-04: Detection Updates
Detection Updates
TVM-04: Are processes, procedures, and technical measures defined, implemented, and evaluated to update detection tools, threat signatures, and compromise indicators weekly (or more frequent) basis?
A rolling schedule of detection, reporting, and mitigation should be established so that all actions to address threats and non-conformance are performed on time and reported to the integrated TVM system for monitoring and oversight. In addition, where applicable, implement automation so that threats and non-conformance are mitigated on time.
Control implemented
Not applicable - A “N/A” answer indicates that the portion of the control in question is out of scope of the assessment. The “SSRM control ownership” column is to be left blank (e.g., greyed out), and optionally the CSP may explain why it is the case (“CSP Implementation Description”).
No - A “No” answer indicates that the portion of the control in question is not implemented, while in scope of the assessment. The CSP has to assign the implementation responsibility of the control to the relevant party under column “SSRM control ownership”, and optionally elaborate on the “why” (has not been implemented), and “what” has to be done for its implementation by that party.
Yes - A “Yes” answer indicates that the portion of the control in question is implemented. The CSP indicates the responsible and accountable parties (SSRM control ownership), and optionally elaborates on the implementation “how-to” per relevant party CSP and/or CSC.
Control ownership
CSP-owned - The CSP is entirely responsible and accountable for the CCM control implementation.
CSC-owned - The Cloud Service Customer (CSC) is entirely responsible and accountable for the CCM control implementation.
Third-party - The third-party CSP in the supply chain (e.g., an IaaS provider) is responsible for CCM control implementation, while the CSP is fully accountable.
Shared CSP and CSC - Both the CSP and CSC share CCM control implementation responsibility and accountability.
Shared CSP and third party - Any CCM control implementation responsibility is shared between CSP and the third party, but the CSP remains fully accountable.
