Description
Users signed on to a WebSphere MQ queue manager could leave their terminals unattended for long periods of time. This may allow unauthorized individuals to gain access to WebSphere MQ resources and application data. This exposure could compromise the availability, integrity, and confidentiality of some system services and application data.

ℹ️ Check
Refer to the following report produced by the z/OS Data Collection: - MQSRPT(ssid) Note: ssid is the queue manager name (a.k.a., subsystem identifier). Automated Analysis Refer to the following report produced by the z/OS Data Collection: - PDI(ZWMQ0020) Review the ssid report(s) and perform the following steps: 1. Find the DISPLAY SECURITY command to locate the start of the security parameter settings. 2. Review the CSQH015I and CSQH016I messages to determine the Timeout and Interval parameter settings respectively. 3. Repeat these steps for each queue manager ssid. The standard values are: TIMEOUT(15) INTERVAL(5) If the Timeout and Interval values conform to the standard values, this is not a finding. If the Timeout and/or Interval values do not conform to the standard values, this is a finding.
