The cyber incident scenario tests should include high-impact-low-probability events and scenarios that may result in failure. Common cyber incident scenarios include distributed denial of service (DDoS) attacks, system intrusion, data exfiltration and system disruption. Licensees should regularly use threat intelligence to update the scenarios so that they remain current and relevant. Licensees should periodically review current cyber incident scenarios for the purpose of assessing the licensee’s ability to detect and respond to these scenarios if they were to occur.
