SV-61045r1_rule The system must not respond to ICMP broadcast timestamp requests.

Vulnerability 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 response to ICMP broadcast timestamp requests is disabled. # ipadm show-prop -p _respond_to_timestamp_broadcast -co current ip If the output of this command is not "0", this is a finding.

Fix text

The Network Management profile is required. Disable respond to timestamp broadcasts. # pfexec ipadm set-prop -p _respond_to_timestamp_broadcast=0 ip

Pro Tips

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: text/turtle or Accept: application/rdf+xml.
