SI-5 : SECURITY ALERTS, ADVISORIES, AND DIRECTIVES
a. Receives information system security alerts, advisories, and directives from designated external organizations on an ongoing basis;
b. Generates internal security alerts, advisories, and directives as deemed necessary;
c. Disseminates security alerts, advisories, and directives to [Assignment: organization-defined list of personnel (identified by name and/or by role)]; and
d. Implements security directives in accordance with established time frames, or notifies the issuing organization of the degree of noncompliance.
Security alerts and advisories are generated by the United States Computer Emergency Readiness Team (US-CERT) to maintain situational awareness across the federal government. Security directives are issued by OMB or other designated organizations with the responsibility and authority to issue such directives. Compliance to security directives is essential due to the critical nature of many of these directives and the potential immediate adverse affects on organizational operations and assets, individuals, other organizations, and the Nation should the directives not be implemented in a timely manner.
