macOS 15 - Sequoia
The macOS system must configure audit log files to be owned by root
Description
Audit log files must be owned by root.The audit service must be configured to create log files with the correct ownership to prevent normal users from reading audit logs.Audit logs contain sensitive data about the system and users. If log files are set to be readable and writable only by system administrators, the risk is mitigated.Satisfies: SRG-OS-000057-GPOS-00027, SRG-OS-000058-GPOS-00028, SRG-OS-000059-GPOS-00029, SRG-OS-000256-GPOS-00097, SRG-OS-000257-GPOS-00098, SRG-OS-000258-GPOS-00099
