SV-89489r1_rule The MQ Appliance SSH interface to the messaging server must prohibit the use of cached authenticators after 600 seconds.

Vulnerability discussion

When the messaging server is using PKI authentication, a local revocation cache must be stored for instances when the revocation cannot be authenticated through the network, but if cached authentication information is out of date, the validity of the authentication information may be questionable.

Check content

In the MQ Appliance WebGUI, Go to Administration (gear icon) >> Access >> RBM Settings. Verify that cache setting is defined and specifies "600" seconds. If the time period is not set to "600" seconds, this is a finding.

Fix text

In the MQ Appliance WebGUI, Go to Administration (gear icon) >> Access >> RBM Settings. Limit cache settings to "600" seconds.

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.
