MariaDB has five global variables that can be set so that connections will be closed after a certain period of inactivity. Check the values for these variables and verify they correspond to security procedures defined: MariaDB> SHOW GLOBAL VARIABLES LIKE '%timeout%'; interactive_timeout - Time in seconds that the server waits for an interactive connection (one that connects with the mysql_real_connect() CLIENT_INTERACTIVE option) to become active before closing it. See also wait_timeout. wait_timeout - Time in seconds that the server waits for a connection to become active before closing it. The session value is initialized when a thread starts up from either the global value, if the connection is noninteractive, or from the interactive_timeout value, if the connection is interactive. In situations where transactions may be started, but not committed or rolled back, more granular control and a shorter timeout may be desirable so as to avoid locks being held for too long. idle_transaction_timeout idle_write_transaction_timeout idle_readonly_transaction_timeout Review system documentation to obtain the organization's definition of circumstances requiring automatic session termination. If the documentation explicitly states that such termination is not required or is prohibited, this is not a finding. If the security procedures require server-side session termination within a specified amount of time but MariaDB is not configured accordingly, this is a finding.
