The HPE Alletra Storage ArcusOS device must set an inactive timeout for sessions.

Leaving sessions open indefinitely is a major security risk. An attacker can easily use an already authenticated session to access the hosted application as the previously authenticated user. By closing sessions after a set period of inactivity, the web server can make certain those sessions not closed through the user logging out of an application are eventually closed. Acceptable values are 5 minutes for high-value applications, 10 minutes for medium-value applications, and 20 minutes for low-value applications.

Verify the WSAPI Session Timeout value is set with the following command: %cli showwsapi -d -------------------------------WSAPI Server Configuration-------------------------------- service State: Enabled HPE GreenLake for Block Storage UI State: Active server State: Active HTTPS Port: 443 Number of Sessions Created: 0 System Resource Usage: 96 Number of Sessions Active: 0 Version: 1.14.0 Event Stream State: Enabled Max Number of SSE Sessions Allowed: 5 Number of SSE Sessions Created: 0 Number of SSE Sessions Active: 0 Session Timeout: 10 Minutes Policy : per_user_limit API URL: https://s2475-cluster.lr4-storage.net/api/v1 If "Session Timeout" is set to a value greater than "10 minutes", this is a finding.

Configure the WSAPI Session Timeout to a value less than or equal to 10 minutes: cli% setwsapi -timeout 10
