Use the following
commands to display runtime integrity information:
security system state - Displays the status of system related security
data-corruption - Displays the DATACORRUPTION-DATAINCONSISTENCY errors
collected from all running processes by OSC and SafeC techniques during
System Security Status
example displays the status of system related security features.
switch# show security system state
Non-Executable stack: Yes
Non-Executable heap: Yes
Non-Writable text: Yes
ASLR enabled: Yes
CVE-offset2lib Patch: Present
Randomization entropy: Good
displays information about the following fields:
stack – Indicates whether system prevents execution from stack.
heap – Indicates whether system prevents execution from heap.
text – Indicates whether system prevents text section to be writable.
ASLR enabled –
Indicates whether ASLR is enabled in Linux kernel and system has capability to
randomize all memory sections for binaries compiled with PIC/PIE flags.
Patch – Indicates whether Offset2lib patch is in kernel, so that randomized
memory segment for text and data are not adjacent to libraries.
entropy – Indicates whether entropy of randomization is sufficient.
OSC version –
Indicates the version of OSC library used by applications.
– Indicates the version of SafeC library used by applications.
and SafeC Events
example displays the DATACORRUPTION-DATAINCONSISTENCY errors collected from all
running processes by runtime OSC and SafeC techniques.
