If attribute encryption is required, restrict filesystem access to the LDBM database directory (/var/lib/dirsrv/slapd-<instance>/db/) to ensure only authorized administrators can read database files.","depth":"sunlit","depthScore":24,"depthScoreParts":{"impact":24.2,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
