Discussion

Web server management includes the ability to control the number of users and user sessions that utilize a web server. Limiting the number of allowed users and sessions per user is helpful in limiting risks related to several types of Denial of Service attacks. Although there is some latitude concerning the settings themselves, the settings should follow DoD-recommended values, but the settings should be configurable to allow for future DOD direction. While the DOD will specify recommended values, the values can be adjusted to accommodate the operational requirement of a given system.

Verify that SSMC limits the number of concurrent sessions by doing the following:

1. Log on to SSMC TUI via SSH as ssmcadmin. Press "X" to escape to general bash shell.

2. Execute the following commands:

$ grep ^security.max.active.ui.sessions /opt/hpe/ssmc/ssmcbase/resources/ssmc.properties

security.max.active.ui.sessions=10

$ grep ^security.max.active.ui.per.user.sessions /opt/hpe/ssmc/ssmcbase/resources/ssmc.properties
security.max.active.ui.per.user.sessions=1

If the output of the above commands does not show the values for "security.max.active.ui.sessions" and "security.max.active.ui.per.user.sessions" properties with values set as "10" and "1" respectively, this is a finding.
