What is FISMA Compliance?

FISMA compliance is compliance with The Federal Information Security Management Act (FISMA) is a United States federal law passed in 2002 that made it a requirement for federal agencies to develop, document, and implement an information security and protection program. FISMA is part of the larger E-Government Act of 2002 introduced to improve the management of electronic government services and processes.

FISMA is one of the most important regulations for federal data security standards and guidelines. It was introduced to reduce the security risk to federal information and data while managing federal spending on information security. To achieve these aims, FISMA established a set of guidelines and security standards that federal agencies have to meet. The scope of FISMA has since increased to include state agencies administering federal programs like Medicare. FISMA requirements also apply to any private businesses that are involved in a contractual relationship with the government.

In April 2010 the Office of Management and Budget (OMB) released guidelines which require agencies to provide real time system information to FISMA auditors, enabling continuous monitoring of FISMA-regulated information systems.

FISMA Compliance Requirements

The National Institute of Standards and Technology (NIST) plays an important role in the FISMA Implementation Project launched in January 2003, which produced the key security standards and guidelines required by FISMA. These publications include FIPS 199, FIPS 200, and the NIST 800 series.

The top FISMA requirements include:

• Information System Inventory: Every federal agency or contractor working with the government must keep an inventory of all the information systems utilized within the organization. In addition, the organization must identify the integrations between these information systems and other systems within their network.
• Risk Categorization: Organizations must categorize their information and information systems in order of risk to ensure that sensitive information and the systems that use it are given the highest level of security. FIPS 199 “Standards for Security Categorization of Federal Information and Information Systems” defines a range of risk levels within which organizations can place their various information systems.
• System Security Plan: FISMA requires agencies to create a security plan which is regularly maintained and kept up to date. The plan should cover things like the security controls implemented within the organization, security policies, and a timetable for the introduction of further controls.
• Security Controls: NIST SP 800-53 outlines an extensive catalog of suggested security controls for FISMA compliance. FISMA does not require an agency to implement every single control; instead, they are instructed to implement the controls that are relevant to their organization and systems. Once the appropriate controls are selected and the security requirements have been satisfied, the organizations must document the selected controls in their system security plan.
• Risk Assessments: Risk assessments are a key element of FISMA’s information security requirements. NIST SP 800-30 offers some guidance on how agencies should conduct risk assessments. According to the NIST guidelines, risk assessments should be three-tiered to identify security risks at the organizational level, the business process level, and the information system level.
• Certification and Accreditation: FISMA requires program officials and agency heads to conduct annual security reviews to ensure risks are kept to a minimum level. Agencies can achieve FISMA Certification and Accreditation (C&A) through a four-phased process which includes initiation and planning, certification, accreditation, and continuous monitoring.
