NIST 800-53 is a collection of security controls to safeguard US federal information systems and the organizations that create, collect, process, store, disseminate, and dispose of those systems.
With cyber threats escalating, compliance with rigorous information security frameworks is no mere check-the-box exercise for regulatory compliance. It is absolutely essential to protecting information assets. The National Institute of Standards and Technology (NIST) Special Publication 800-53 offers crucial advice to federal agencies and contractors to improve their information security.
If you’re an IT professional following sector governance on cybersecurity or simply looking to implement a structure to protect your infrastructure and data, NIST 800-53 will be a crucial guide. Here’s a primer on that standard and a ‘cheat sheet’ of what the NIST requirements mean regarding what controls you must implement to achieve compliance.
Much important work is being done to secure our information against exploits, malicious operators, and the myriad of cyber threats that put our infrastructure, national security, and identities at risk. By following NIST 800-53 and implementing the proposed controls, you can take a vital step towards heightening system security.

Understanding NIST 800-53
NIST 800-53 is a compilation of security and privacy controls that can help secure federal information systems and the data processed by those systems.
This framework was developed by the National Institute of Standards and Technology (NIST), a federal agency within the US Department of Commerce that creates measurements and provides standards to help increase innovation and productivity in the country’s ever-changing economy. NIST 800-53 improves the security and resilience of federal information systems from cyber and other similar threats.
To put it mildly, failure to comply with NIST 800-53 is not an option for organizations in the federal space or those that do business with government agencies. FISMA was passed in 2002, establishing NIST as the organizing body for all elements of federal information security.
Covering everything from access control to incident response to risk assessment to system and communications protection—in fact, the standard lists 229 different controls—FISMA represents the most all-encompassing framework for security to date.
Indeed, NIST frequently revises the framework as threats and technologies change, and version 4.0 is scheduled for release next year. So NIST 800-53 is a living document, and agencies and contractors are advised to consult it often for guidance on keeping their security practices current.
Though definitive solutions to the ‘insider threat’ do not exist, conscientious use of these standards will help agencies and contractors better protect themselves and the data they keep from insiders and outsiders.
Preparing for NIST 800-53 Compliance
In preparation for NIST 800-53 compliance, you must document your organization’s security posture and identify the appropriate applicable controls.
Gather information about your organization’s security and compliance status to start with a baseline. This will help you navigate the process of moving toward compliance and prevent you from tackling a NIST 800-53 compliance checklist with the wrong security tools and functions.
The following steps are critical when preparing for compliance:
1. Conduct a Gap Analysis:
A gap analysis should be performed to discover the difference between the current security practices and the NIST 800-53 control requirements.
2. Understand the Context:
Judge the nature of the information you handle, segment systems based on such criteria, and apply controls relative to the level of sensitivity and criticality.
3. Build Cross-Functional Teams:
Bringing key stakeholders to the team – from IT, security, compliance, and absolutely business operations – helps ensure you’ve got all the correct viewpoints in the room and helps ensure that you’ve got buy-in firm-wide.
4. Educate Your Workforce:
Train team members so that everyone understands why NIST 800-53 compliance is important and what they must do to stay compliant.
After completing these preparatory steps, you will be in an excellent position to focus on NIST 800-53’s requirements and be able to use the following compliance checklist in a valuable and effective way. Your compliance process mustn’t be just a box-ticking exercise; rather, you are committed to embedding sound security principles into the heart of work.
