Description
Application management includes the ability to control the number of sessions that utilize an application by all accounts and/or account types. Limiting the number of allowed sessions is helpful in limiting risks related to denial-of-service attacks. Automation Controllers host and expose business logic and application processes. Automation Controller limits the maximum number of concurrent sessions in a manner that affects the entire application server or on an individual application basis. The settings must 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. Satisfies: SRG-APP-000001-AS-000001, SRG-APP-000295-AS-000263
