Guide to Understanding Security Controls: NIST SP 800-53 Rev 5 by Raymond RafaelsThis book enhances the original NIST SP 800-53 rev 5 Security and Privacy Controls for Information Systems publication. NIST SP 800-53 rev 5 is a reference publication that establishes controls for federal information systems and organizations. It is used as a key part in the process of protecting and assessing the security posture of information systems. The security controls protect the confidentiality, integrity, and availability (CIA) of the system and its information. The Publication is enhanced by making the following changes while maintaining the original content:1.Add Illustrations2.Explain Security Controls Purpose and Use in Plain Language (Enhanced Supplemental Guidance) 3.Document Formatting Improvements for Easier Reading 4.Remove Lesser Used Sections
NIST 800-53 R5 Initial Public Draft
NIST 800-53 Rev 5 Draft – Major changes and important dates
The new version is scheduled for publication this summer after months of delays and perhaps for good reason. The public and private sector rely on NIST to help manage risk and threats from hostile attacks, natural disasters, structural failures, human errors and privacy incidents. Rev 5 will provide the latest guidance on security and privacy controls designed to address these risks and threats. Major changes include:. Making privacy controls more outcome-based One of the significant changes with NIST Rev 5 is making security and privacy controls more outcome-based. This is welcome news on the privacy front with many organizations either struggling to comply with privacy regulations or still in the planning phase.
What does the initial public draft tell us about what we can expect in its final version? Even more importantly, what does it mean for organizations seeking to adopt the new guidelines? NIST SP Revision 5 is expected to deliver major updates to the existing fourth revision, which was originally published in Since its inception, this publication has been the de facto guideline for security control implementations, security assessments and Authorization to Operate ATO processes for government information systems. There are many draft changes in the fifth revision, but one of the most significant impacts is that it marks a departure from limiting the control sets to federal information systems. The framework is now recommended for all systems in all industries. In addition to control baseline updates, other major changes NIST anticipates will be in the final version include:.
NIST Rev 5 is on the way, have you read the draft? We regularly use NIST as the criteria for controls assessment for both private and public-sector clients. With our guidance, many of our clients have successfully implemented an industry-appropriate risk management strategy, allowing them to manage their risk profile, make risk-informed strategic decisions, and intentionally select, tailor, and implement key security controls. We have helped private sector clients adopt and modify the NIST risk management framework and provided helpful guidance on how to build or improve an information security program and efficiently address security risk. However, it has now been over 5 years since the original release of NIST Rev 4, and over 3 years since the last major content update.
Commerce Department, is responsible for developing and enabling information security standards and guidelines across federal agencies. NIST developed the voluntary risk-based Cybersecurity Framework following executive order issued by former President Obama in The framework is divided into five different functions: identify, protect, detect, respond, and recover.

What is NIST Cybersecurity Framework?
NIST develops and issues standards, guidelines, and other publications to assist federal agencies in implementing the Federal Information Security Modernization Act of FISMA and to help with managing cost effective programs to protect their information and information systems. This includes selecting an initial set of baseline security controls based on a FIPS worst-case impact analysis, tailoring the baseline security controls, and supplementing the security controls based on an organizational assessment of risk. A key part of the assessment and authorization formerly certification and accreditation process for federal information systems is selecting and implementing a subset of the controls safeguards from the Security Control Catalog NIST , Appendix F. These controls are the management, operational, and technical safeguards or countermeasures prescribed for an information system to protect the confidentiality, integrity, and availability of the system and its information. Agencies have the ability to adjust these controls and tailor them to fit more closely with their organizational goals or environments.
The information security landscape is consistently changing. As new risks and mitigation strategies arise, frameworks must evolve or risk becoming irrelevant. The most recent revision to the framework—NISTRev-5—has been purposely revised to be more generally applicable to all types of businesses including state, local and tribal governments as well as the public and private sectors. The revision also addresses a broader scope of systems including industrial control systems, IoT devices, and other physical cyber devices and systems. NIST has changed the structure of controls to make them more easily readable—which seems to be an extension of the effort to make the framework more easily accessible to all types of organizations.
