Title: Security Alerts & Advisories

Practice:
Monitor system security alerts and advisories and take action in response.

CMMC Clarification:
Organizations should receive security alerts, advisories, and directives from reputable external organizations. You base identification of these organizations on sector, industry, and the technology you use. There are many ways to received alerts and advisories and may include:
• signing up for email distributions;
• subscribing to RSS feeds; and
• attending meetings.

Organizations should review alerts and advisories for applicability as they receive them. An organization decides on its own review cycle. The more frequent the alerts and advisories, the more frequent the reviews. This ensures that the organization has the most up-to-date information.

External alerts and advisories may prompt an organization to generate internal security alerts, advisories, or directives. Share these with all personnel with a need-to-know. The individuals should take action to respond to the alerts. Actions vary according to the alert or advisory. Sometimes it may require a system configuration update. Other times, the organization may use the information for situational awareness purposes.

Example
One of your IT responsibilities is to protect your organization's computers. As part of your job you decide you need to pay attention to security alerts and advisories to keep aware of the latest threats and risks. You decide to receive alerts from US-CERT and a set of ISACs. You review the alerts on a weekly basis to determine if they are relevant to your organization. When you identify one you follow your plan to correct information system flaws in a timely manner, such as installing a patch.
