Description
Without mapping the certificate used to authenticate to the user account, the ability to determine the identity of the individual user or group will not be available for forensic analysis.
ℹ️ Check
Any keys or Certificates must be managed in ICSF or the external security manager and not in UNIX files.
From the ISPF Command Shell enter:
OMVS
enter
find / -name *.kdb
and
find / -name *.jks
If any files are present, this is a finding.
✔️ Fix
Define all Keys/Certificates to ICSF or the security database.
Remove all .kdb and .jks key files.
