The most important component of asset decommissioning from a data risk perspective is the secure destruction of data on the asset.

Data Sanitization: Ensures that all sensitive information is irretrievably erased before disposal or repurposing.

Techniques: Physical destruction, secure wiping, or degaussing depending on the storage medium.

Risk Mitigation: Prevents data leakage if the asset falls into unauthorized hands.

Incorrect Options:

A . Informing the data owner: Important but secondary to data destruction.

C . Updating the CMDB: Administrative task, not directly related to data risk.

D . Removing monitoring: Important for system management but not the primary risk factor.

Exact Extract from CCOA Official Review Manual, 1st Edition:

Refer to Chapter 9, Section 'Asset Decommissioning,' Subsection 'Data Sanitization Best Practices' - Data destruction is the most critical step to mitigate risks.
