The vCenter Server must have new Key Encryption Keys (KEKs) reissued at regular intervals for vSAN encrypted datastore(s).

Description
The KEK for a vSAN encrypted datastore is generated by the Key Management Server (KMS) and serves as a wrapper and lock around the Disk Encryption Key (DEK). The DEK is generated by the host and is used to encrypt and decrypt the datastore. A shallow rekey is a procedure in which the KMS issues a new KEK to the ESXi host, which rewraps the DEK but does not change the DEK or any data on disk. This operation must be done on a regular, site-defined interval and can be viewed as similar in criticality to changing an administrative password. If the KMS is compromised, a standing operational procedure to rekey will put a time limit on the usefulness of any stolen KMS data.

Who does this work

10 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-258954r1003610_chk)

If vSAN is not in use, this is not applicable. Interview the system administrator (SA) to determine that a procedure has been put in place to perform a shallow rekey of all vSAN encrypted datastores at regular, site-defined intervals. VMware recommends a 60-day rekey task, but this interval must be defined by the SA and the ISSO. If vSAN encryption is not in use, this is not a finding. If vSAN encryption is in use and a regular rekey procedure is not in place, this is a finding.

Fix Text (F-62603r1003609_fix)

If vSAN encryption is in use, ensure a regular rekey procedure is in place. To generate new encryption keys for vSAN, do the following: From the vSphere Client, go to Host and Clusters. Select the vCenter Server >> Select the cluster >> Configure >> vSAN >> Services >> Data Services. Select "Generate New Encryption Keys" and optionally generate new DEKs and click "Generate".
