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 group-owned by a system group, the core dumps contained in the directory may be subject to unauthorized access.
The root role is required. This check applies to the global zone only. Determine the zone that you are currently securing. # zonename If the command output is "global", this check applies. Determine the location of the system dump directory. # dumpadm | grep directory Check ownership of the core dump data directory. # ls -l [savecore directory] If the directory is not group-owned by root, this is a finding. In Solaris 11, /var/crash is linked to /var/share/crash.

Lavender hyperlinks in small type off to the right (of CSS
class id, if you view the page source) point to
globally unique URIs for each document and item. Copy the
link location and paste anywhere you need to talk
unambiguously about these things.
You can obtain data about documents and items in other
formats. Simply provide an HTTP header Accept:
