NIST cybersecurity framework

Cybersecurity is defined as the collection of methods, technologies, and processes used to protect the confidentiality, integrity, and availability of computer systems, networks, and data from cyber-attacks or unauthorised access. The primary goal of cyber security is to protect all organisational assets from both external and internal threats, as well as natural disaster disruptions.

Because organisational assets are comprised of numerous disparate systems, an effective and efficient cyber security posture necessitates coordinated efforts across all of their information systems.

What does NIST Cybersecurity Framework do?

The NIST cybersecurity framework is a valuable resource for organising and improving your cybersecurity programme. It is a set of guidelines and best practices designed to assist organisations in developing and improving their cybersecurity posture. The framework suggests a set of recommendations and standards to help organisations better prepare for identifying and detecting cyber-attacks, as well as guidelines for responding to, preventing, and recovering from cyber incidents.

This framework, developed by the National Institute of Standards and Technology (NIST cybersecurity framework), addresses the lack of standards in cybersecurity by providing a consistent set of rules, guidelines, and standards for organisations to use across industries. The National Institute of Standards and Technology NIST Cybersecurity Framework (NIST CSF) is widely regarded as the gold standard for developing a cybersecurity programme. Whether you’re just getting started with a cybersecurity programme or you already have one in place, the framework can add value by serving as a top-level security management tool that helps assess cybersecurity risk across the organisation.

The NIST Cybersecurity Framework 5 Core Functions

NIST cybersecurity framework


The Identify function is responsible for laying the groundwork for a successful cybersecurity programme. This function contributes to the development of an organisational understanding of cybersecurity risk to systems, people, assets, data, and capabilities. This function emphasised the importance of understanding the business context, the resources that support critical functions, and the associated cybersecurity risks in order to enable an organisation to focus and prioritise its efforts in accordance with its risk management strategy and business needs. This group’s essential activities include:

  • Identifying physical and software assets as the foundation for an asset management programme
  • Identifying the business environment of the organisation, including its role in the supply chain
  • Identifying established cybersecurity policies to define the governance programme, as well as legal and regulatory requirements regarding the organization’s cybersecurity capabilities
  • To assess risk, we identify asset vulnerabilities, threats to internal and external organisational resources, and risk response activities.
  • Developing a risk management strategy, which includes determining risk tolerance
  • Developing a supply chain risk management strategy that includes priorities, constraints, risk tolerances, and assumptions used to support risk decisions related to supply chain risk management is challenging.


The Protect function outlines appropriate safeguards to ensure critical infrastructure services are delivered and supports the ability to limit or contain the impact of a potential cybersecurity event. This group’s critical activities include:

  • Implementing identity management and access control safeguards within the organisation, including physical and remote access,
  • Staff empowerment through security awareness training, which includes role-based and privileged user training,
  • Creating data security safeguards that are in line with the organization’s risk management strategy to protect the confidentiality, integrity, and availability of information.
  • Implementing processes and procedures to maintain and manage the security of information systems and assets
  • maintaining organisational resources, including remote maintenance activities.
  • technology management to ensure system security and resilience in accordance with organisational policies, procedures, and agreements.


It is critical to detect potential cybersecurity incidents, and this function defines the appropriate activities to detect the occurrence of a cybersecurity event in a timely manner. This function’s activities include:

  • Making certain that anomalies and events are detected and that their potential impact is understood.
  • Continuous monitoring is being set up to keep an eye on cybersecurity events and make sure that protective measures, like network and physical activities, are working.
  • The Respond function focuses on appropriate activities to take action in the event of a detected cybersecurity incident and helps to limit the impact of a potential cybersecurity incident. This function’s essential activities include:
  • Ensuring that the response planning process is followed both during and after an incident
  • Managing internal and external stakeholder communications during and after an event
  • Analyzing the incident to ensure an effective response and supporting recovery activities such as forensic analysis and incident impact
  • Executing mitigation activities to prevent an event from spreading and to resolve the incident
  • Detection and response activities can be made better by using what we’ve learned from past and current activities.


The Recover function identifies appropriate activities to renew and maintain resilience plans, as well as to restore any capabilities or services that have been compromised as a result of a cybersecurity incident. To mitigate the impact of a cybersecurity incident, it is imperative that normal operations resume as soon as possible. This function’s essential activities somewhat overlap with those of Respond and include:

  • Ensure that the organisation has recovery planning processes and procedures in place to restore systems and/or assets affected by cybersecurity incidents.
  • Improving existing strategies and implementing improvements based on lessons learned
  • Internal and external communications are coordinated during and after a cybersecurity incident.

What are the benefits of using the NIST Cybersecurity Framework?

First, let’s take a step back and go over some of the most pressing cybersecurity concerns.

  • You are concerned about unknown risks and vulnerabilities.
  • You do not have an accurate inventory of assets that must be safeguarded.
  • Your team spends a lot of time on things that won’t make a difference, but you’d rather they focus on real risks.
  • You want to know how to deal with risky items given your current tools and what’s on the market.
  • Your coworkers who aren’t on the security team don’t know much about cyber risk, so they don’t “own” important tasks for reducing it.
  • Your board has begun to inquire about quantifying the risk reduction outcomes of the strategic cybersecurity plan that your team has been implementing. “Are we NIST compliant?”

The framework can assist you in dealing with these difficulties. You will be able to learn from how other people have dealt with similar problems in the past.

The framework’s goal is to assist you in prioritising cybersecurity investments and decisions. The framework also helps you figure out how mature your programme is and gives you a way to talk about it with people like your senior management and board of directors.

How to Begin Using the NIST Cybersecurity Framework

Aligning with the framework entails listing all of your activities and labelling them with one of the five function labels. The Identify label, for example, will be for tools that help you inventory your assets. Firewalls and Crowdstrike will be included in Protect. However, depending on their capabilities, they would be placed in Detect alongside your IDS and SIEM. Respond contains your incident response tools and playbooks. Recover includes backup and recovery tools.

After completing this exercise, some of your buckets may feel more empty than others, and you may be uneasy about the corresponding function description in the image above. That’s great; you can now articulate what your cybersecurity programme is lacking.
