History of the NIST Cybersecurity Framework

The National Institute of Standards and Technology (NIST) developed the Cybersecurity Framework in response to Executive Order 13636. They created it out of a need for better cybersecurity practices across various industries.

President Barack Obama issued the order in 2013, recognizing that the national and economic security of the United States depends on the reliable functioning of critical infrastructure. This infrastructure, however, was increasingly vulnerable to cybersecurity threats. The executive order directed the development of a voluntary framework to help organizations manage cybersecurity risks within their broader risk management processes.

NIST published the first version of the Cybersecurity Framework in February 2014. NIST designed it for various businesses and organizations, from small companies to large corporations and across various sectors. The framework offers a common language for understanding, managing, and expressing cybersecurity risks internally and externally. For more information on the latest updates, check out NIST Version 2.0.

2. Identify Your Needs

Every organization is different, so it's important to identify your specific cybersecurity needs. Consider your organization's size, the nature of your data, and the potential risks you face, such as SQL injection and XSS (Cross-Site Scripting) attacks.

3. Assess Your Current State

Conduct a thorough assessment of your current cybersecurity measures. It will serve as a baseline for improvements.

4. Develop a Target Profile

After understanding your current state, create a target profile that outlines your organization's desired cybersecurity outcomes. This profile should align with your business objectives and regulatory requirements.

5. Create an Action Plan

Based on the gaps between your current state and your target profile, develop an action plan for reaching your cybersecurity goals.

6. Implement, Monitor, and Update

Once your plan is in place, begin implementing new cybersecurity measures. Regularly monitor and review their effectiveness, and be prepared to update your strategy as needed.

Remember, the NIST Cybersecurity Framework is a continuous process rather than a one-time task. Regular check-ups and changes will help keep your online safety strong as the digital world changes.

Core Functions of the NIST Cybersecurity Framework

The National Institute of Standards and Technology (NIST) has organized its framework into core functions that outline positive cybersecurity outcomes. These functions include:

Core Functions of the NIST Cybersecurity Framework

1. Identify

The Identify function assists in developing an organizational understanding to manage cybersecurity risk to systems, people, assets, data, and capabilities. It involves asset management, business environment, governance, risk assessment, risk management strategy, and supply chain risk management.

2. Protect

The Protect function outlines appropriate safeguards to ensure the delivery of critical infrastructure services. It includes identity management and access control, awareness and training, data security, information protection processes and procedures, maintenance, and protective technology.

3. Detect

The Detect function defines activities to identify the occurrence of a cybersecurity event in a timely manner. It involves continuous security monitoring, anomalies and events detection, and detection processes.

4. Respond

The Respond function includes the appropriate activities to take action regarding a detected cybersecurity incident. It covers response planning, communications, analysis, mitigation, and improvements.

5. Recover

The Recover function identifies appropriate activities to maintain plans for resilience and restore any capabilities or services that a cybersecurity incident impairs. It includes recovery planning, improvements, and communications.

NIST Cybersecurity Framework Implementation Tiers

NIST introduces 'Implementation Tiers' to help organizations gauge and improve their approach to managing cybersecurity risks. These tiers, ranging from 'Partial' (Tier 1) to 'Adaptive' (Tier 4), provide a clear path for enhancing cybersecurity measures based on the organization's specific needs and resources.

NIST Framework Implementation Tiers

1. Partial (Tier 1)

In the first tier, an organization's approach to cybersecurity risk management needs to be formalized and is often reactive rather than proactive. The processes might be ad hoc and conducted in a more coordinated manner.

There is limited awareness of cybersecurity risk at the organizational level, which means the organization's defenses might need to be fully prepared to handle potential threats. This tier signals the need for improvement in understanding and managing cybersecurity risks.

2. Risk-Informed (Tier 2)

In this scenario, the organization has implemented some risk management processes, but the organization may not consistently apply them across the entire organization.

The organization is conscious of cybersecurity risk but may not include understanding and handling this risk as part of an organization-wide strategy. The organization acknowledges the need for a cybersecurity risk management program but lacks the broader perspective to address it holistically.

3. Repeatable (Tier 3)

The organization formally approves and consistently implements risk management practices in the third tier. There is an organization-wide approach to managing cybersecurity risks.

The organization has standardized its cybersecurity practices and follows them regularly. The risk management process is updated when necessary, based on changes in the organization's business requirements or changes in the cybersecurity world.

4. Adaptive (Tier 4)

At this level, the organization is at an advanced stage of cybersecurity risk management. The organization not only has established cybersecurity practices in place but also adapts its practices based on lessons learned from past experiences and predictive indicators derived from ongoing cybersecurity activities. The organization is capable of responding to changing cybersecurity threats and risks dynamically and effectively.
