Discussion

By accurately determining the system's clock state, an attacker can more effectively attack certain time-based pseudorandom number generators (PRNGs) and the authentication systems that rely on them.

Check Content

Determine if ICMP time stamp responses are disabled.

# ipadm show-prop -p _respond_to_timestamp -co current ip


If the output of both commands is not "0", this is a finding.

Fix Text

The Network Management profile is required.

Disable source respond to timestamp.

# pfexec ipadm set-prop -p _respond_to_timestamp=0 ip
