Title

IBM z/OS, for PKI-based authentication, must use the ICSF or ESM for key management. (Cat II impact)

Discussion

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.

Check Content

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 Text

Define all Keys/Certificates to ICSF or the security database. Remove all .kdb and .jks key files.
