Discussion [NIST SP 800-171 R2]

There 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 Discussion

Solicit 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;
  • attending meetings.

Review alerts and advisories for applicability as they are received. The frequency of the reviews should be based on the frequency of the alerts and advisories to ensure you have the most up-to-date information.

External alerts and advisories may prompt you to generate internal security alerts, advisories, or directives, and share these with all personnel with a need-to-know. The individuals should assess the risk related to a given alert and act to respond as appropriate. Sometimes it may require a configuration update. Other times, the information may also require adjusting system architecture in order to thwart a threat described in an advisory.
