Monitor system security alerts and advisories and take action in response.
DiscussionThere are many publicly available sources of system security alerts and advisories. The United States Computer Emergency Readiness Team (US-CERT) generates security alerts and advisories to maintain situational awareness across the federal government and in nonfederal organizations. Software vendors, subscription services, and relevant industry information sharing and analysis centers (ISACs) may also provide security alerts and advisories. Examples of response actions include notifying relevant external organizations, for example, external mission/business partners, supply chain partners, external service providers, and peer or supporting organizations. NIST SP 800-161 provides guidance on supply chain risk management.
Further DiscussionSolicit and receive security alerts, advisories, and directives from reputable external organizations. Identify sources relevant to the industry and technology used by your company. Methods to receive alerts and advisories may include:
- signing up for email distributions;
- subscribing to RSS feeds; and
- attending meetings.
ExampleYou monitor security advisories each week. You review the alert emails and online subscription service alerts to determine which ones apply [b]. You create a list of the applicable alerts and research what steps you need to take to address them. Next, you generate a plan that you review with your change management group so that the work can be scheduled [c].
