SV-61053r1_rule The system must not respond to broadcast ICMP echo requests.

Vulnerability discussion

ICMP echo requests can be useful for reconnaissance of systems and for denial of service attacks.

Check content

Determine if ICMP echo requests response is disabled. # ipadm show-prop -p _respond_to_echo_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 echo broadcast. # pfexec ipadm set-prop -p _respond_to_echo_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.
