  • SRG-NET-000364-FW-000035

    Group

    Group
  • The FortiGate firewall must generate an alert that can be forwarded to, at a minimum, the Information System Security Officer (ISSO) and Information System Security Manager (ISSM) when denial-of-service (DoS) incidents are detected.

    Without an alert, security personnel may be unaware of major detection incidents that require immediate action, and this delay may result in the loss or compromise of information. The firewall gen...
