EX16-MB-000150 - Exchange must protect audit data against unauthorized deletion.


Log files help establish a history of activities and can be useful in detecting attack attempts or determining tuning adjustments to improve availability. Audit log content must always be considered sensitive and in need of protection. Audit data available for modification by a malicious user can be altered to conceal malicious activity. Audit data might also provide a means for the malicious user to plan unauthorized activities that exploit weaknesses.

The contents of audit logs are protected against unauthorized access, modification, or deletion. Only authorized auditors and the audit functions should be granted 'Read' and 'Write' access to audit log data.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.


Update the EDSP to specify the authorized groups or users that should have 'Delete' permissions for the audit data or verify that this information is documented by the organization.

Restrict any unauthorized groups' or users' 'Delete' permissions for the audit logs.
