Relevant Standards and Organizations 13 and Regulations," some of the more common regulations are summarized here in order to help you determine which standards you should be striving to meet. NIST Special Publications (800 Series) NIST's 800 series documents provide best practices and information of general interest to information security. All 800 series documents concern information secu- rity and should be used as references where applicable. Of particular relevance to industrial network security is SP 800-53 ("Recommended Security Controls for Federal Information Systems"), which defines many aspects of information secu- rity procedures and technologies, and SP 800-82 ("Guide to Supervisory Control and Data Acquisition [SCADA] and Industrial Control Systems Security"), which discusses industrial control system security specifically. Although of the entire SP 800-53 is applicable to the protection of critical infrastructures, the technical aspects defined under SP 800-53 as Access Control, Security Assessment and Authorization, Configuration Management, Identification and Authentication, Risk Assessment, System and Communications Protection, and System and Information Integrity are directly applicable to industrial networks. 5
