The Federal Information Security Management Act (FISMA) was originally released in December 2002 and established the importance of information security principles and practices within the Federal Government, noting that information security was “critical to the economic and national security interests of the United States.1” The emphasis of the FISMA was to establish a “risk-based policy for cost-effective security. 1”
With the passage of FISMA, each Federal agency was then responsible for developing and implementing an information security program for the information systems under its control to include any information systems that were managed by contractors on behalf of the agency. The goals of FISMA were to reduce information security risk and expenditures for the Federal agencies, specifically they were to implement “adequate security, or security commensurate with risk. 1”
With the passage of FISMA in 2002, its implementation was divided into two phases. Phase I (2003-2012) established guidelines and security standards for use across the Federal government. These guidelines and standards were part of the FISMA Implementation Project that started in January 2003. The specific documents and guidelines initially developed as part of Phase I of FISMA implementation include the following (as depicted with the latest revision):
- Federal Information Processing Standard (FIPS) 199: Standards for Security Categorization of Federal Information and Information Systems (Feb 2004)
- FIPS 200: Minimum Security Requirements for Federal Information and Information Systems (Mar 2006)
- SP 800-53: Security and Privacy Controls for Federal Information Systems and Organizations (Rev 4, April 2013, updated Jan 2015). Note: Rev 5 is currently in Draft as of Feb 2016.
- SP 800-59: Guideline for Identifying an Information System as a National Security System (Aug 2003)
- SP 800-60: There are two volumes that make up SP 800-60. Volume 1 (Rev 1, Aug 2008) is the Guide for Mapping Types of Information Systems to Security Categories and Volume II (Rev 1, Aug 2008) is the Appendices to Volume I.
Additional Phase I documents were developed to supplement the original list. As of May 2016 the following additional documents have been included2:
- Special Publication (SP) 800-18: Guide for Developing Security Plans for Federal Information Systems (Rev 1, Feb 2006)
- SP 800-30: Guide for Conducting Risk Assessments (Rev 1, Sep 2012)
- SP 800-37: Guide for Applying the Risk Management Framework to Federal Information Systems: A Security Life Cycle Approach (Rev 1, updated Jun 5, 2014)
- SP 800-39: Managing Information Security Risk: Organization, Mission, and Information System View (March 2011)
- SP 800-53A: Assessing Security and Privacy Controls in Federal Information Systems and Organizations: Building Effective Assessment Plans (Rev 4, Dec 2014, updated as of 12/18/14)
- SP 800-137: Information Security Continuous Monitoring (ISCM) for Federal Information Systems and Organizations (Sep 2011)
- SP 800-160: (DRAFT) Systems Security Engineering Guideline: An Integrated Approach to Building Trustworthy Resilient Systems (Sep 2016)
As you can see, there are a large number of documents that have been produced to assist with the implementation of security within Federal information systems. The above list, though, is not all inclusive. There are many more ranging from application whitelisting (SP 800-167) to Networks of ‘Things’ (SP800-183).
The initial set of documents were key as they assisted the Federal agencies with understanding the information processed by their information systems and the associated security impact levels (low, medium and high) against confidentiality, integrity and availability. The resulting categorization of the system guides the applicable security controls as outlined in the SP 800-53 security control catalog. Another important document released as part of Phase I of the FISMA Implementation was SP 800-59. This document defined the method for identifying a National Security System and gave the authority to develop information security policies, guidelines and standards for National Security Systems (NSS) to the Department of Defense (DoD) and the Director, Central Intelligence (DCI) (specifically for systems processing intelligence information). All other Federal Systems were under the authority of the Secretary of Commerce.
With the authority for National Security Systems with the DoD and DCI, DoD and Intelligence Community specific information security guidelines, processes and standards were developed. As a result, the DoD Instruction 8500.2, Information Assurance (IA) Implementation and the Director of Central Intelligence (DCID) 6/3 Protecting Sensitive Compartmented Information within Information Systems documents were developed. With the move toward ICD 503 in the Intelligence Community, DCID 6/3 was rescinded and replaced by standards, policies and guidelines established by the National Institute of Standards and Technology (NIST) or the Committee on National Security Systems (CNSS). In the DoD community, the DoD Risk Management Framework (RMF) has replaced the Defense Information Assurance Certification and Accreditation Program (DIACAP) and aligned its RMF processes with the NIST RMF process. The DoD RMF also incorporates the NIST security controls as defined in SP 800-53.
Today, many, if not all DoD and Intelligence Community organizations have moved to NIST 800-53 as their security controls catalog and have customized their Risk Management Framework based on the framework defined in SP 800-37. The primary framework steps outlined in SP 800-37 are identified below.
- Categorize Information System
- Select Security Controls
- Implement Security Controls
- Assess Security Controls
- Authorize Information Systems
- Monitor Security Controls
Phase II of the FISMA Implementation Project (2007-2012) focused on establishing a common understanding in the application of NIST documentation supporting the Risk Management Framework (RMF). To do this, multiple initiatives were implemented which produced additional reference materials “intended to promote common approaches for assessing the extent to which the security controls are implemented correctly, operating as intended, and producing the desired outcome with respect to meeting the security requirement for the systems, including information technology products and services used in security control implementation.2” This phase included initiatives aimed at training, support tools (e.g. the National Vulnerability Database (NVD) and the Security Content Automation Protocol (SCAP), product and services assurance, ISO harmonization (specifically identifying common relationships and mappings to the ISO/IEC 27000 series) and organizational assessment capabilities.
Another large focus of the FISMA was to specifically detail responsibilities under the Act between the Federal agencies, NIST and the Office of Management and Budget (OMB). Under the FISMA, the following responsibilities were defined:
- Federal Agencies: Develop and implement an integrated risk based information security program. As part of this effort, Federal agencies were responsible for identifying all of their information systems, categorize their information systems, define and implement applicable controls, test the controls and continuously monitor their implementation to ensure the controls are operating effectively.
- NIST: Develop the security guidelines and standards for implementation across all Federal agencies. These include guidelines and standards for categorization of information systems, comprehensive definition of security controls and risk management methodologies, among others.
- OMB: Define and implement methods for oversight (e.g. define a standardized process for reporting FISMA compliance). Report to Congress on the status of FISMA compliance across the Federal government.
In December 2014, FISMA was amended to “(1) reestablish the oversight authority of the Director of the Office of Management and Budget (OMB) with respect to agency information security policies and practices, and (2) set forth authority for the Secretary of Homeland Security (DHS) to administer the implementation of such policies and practices for information systems.3” Other notable requirement of the amended FISMA include the following:
- The annual report to Congress must include an assessment of agency compliance with the OMB data breach notification procedures.
- Automated tools are provided to assist in the agency information security programs (to support risk assessment, testing, detecting and reporting incidents, etc.)
- OMB is directed to develop guidance on what constitutes a major incident
- Agencies must report to unauthorized acquisition or access to Congress within 30 days. Agencies must also notify all affected individuals.
As part of their responsibilities under FISMA, NIST has done an outstanding job with developing comprehensive information security standards and guidelines. In addition to the above mentioned documents, there are many more covering various other aspects of an information security program. While developed for the Federal government, NIST documentation can be leveraged to enhance any commercial information security program as well.
