GEN003520 - The kernel core dump data directory must be owned by root.
Information
Kernel core dumps may contain the full contents of system memory at the time of the crash. As the system memory may contain sensitive information, it must be protected accordingly. If the kernel core dump data directory is not owned by root, the core dumps contained in the directory may be subject to unauthorized access.NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.
Solution
Change the owner of the kernel core dump data directory to root.# chown root /var/adm/ras
Supplementary Information: The location of the kernel dump area should be moved out of /var/adm/ras. This directory may be world read/writeable. A suggestion would be to create /var/adm/kcore; chown root:sys /var/adm/kcore; chmod 700 /var/adm/kcore.
Change where the system copies its kernel core files to.
sysdumpdev -d /var/adm/kcore
