03.14.17E System-Generated Alerts

Statement

Alert {{ insert: param, A.03.14.17E.ODP.01 }} when the following system-generated indications of compromise or potential compromise occur: {{ insert: param, A.03.14.17E.ODP.02 }}.

Guidance

Alerts may be generated from different sources internal to the system, including audit records, inputs from malicious code protection mechanisms, intrusion detection or prevention mechanisms, or boundary protection devices such as firewalls, gateways, and routers. Compromise indicators could include CUI being accessed by unauthorized users or when CUI traverses architecture outside of defined data flows. Alerts can be automated and transmitted telephonically, by electronic mail messages, or by text messaging. Organizational personnel on the alert notification list can include system administrators, mission or business owners, system owners, information owners or stewards, chief information security officers, and system security officers. This requirement is sourced to a control tailored out of the SP 800-53B .13 moderate baseline in SP 800-171.

Statement

• (includes detect) Reduce risk due to ignorance of threat events and possible replicated or similar threat events in the same or similar environments.

  • Reduce likelihood of impact.

  • The adversary loses the advantage of stealth as defenders are better prepared by developing and sharing threat intelligence.

Assessment objective

{{ insert: param, A.03.14.17E.ODP.01 }} are alerted when system-generated {{ insert: param, A.03.14.17E.ODP.02 }} occur.

Assessment method

• System and information integrity policy system and information integrity procedures system security plan system audit records procedures addressing system monitoring tools and techniques system monitoring tools and techniques documentation list of personnel selected to receive alerts system configuration settings and associated documentation documentation of alerts generated based on compromise indicators other relevant documents or records

Assessment method

• Personnel with information security responsibilities system developers personnel installing, configuring, and/or maintaining the system personnel responsible for monitoring the system personnel on the system alert notification list personnel responsible for the intrusion detection system system/network administrators

Assessment method

• Processes for intrusion detection and system monitoring mechanisms supporting and/or implementing intrusion detection and system monitoring capabilities mechanisms supporting and/or implementing alerts for compromise indicators
