The NIST Cybersecurity Framework was first released in 2014 in response to an executive order by President Obama aimed at improving critical infrastructure cybersecurity in the United States. The framework is a voluntary set of guidelines based on existing standards, guidelines, and practices for organizations to manage and mitigate cybersecurity risks. Its goal is to foster risk and cybersecurity management communications amongst both internal and external organizational stakeholders. Since its inception, it has become the cornerstone for organizations seeking to bolster their cybersecurity defenses.

The main components of the NIST cybersecurity framework include: the Core, the Implementation Tiers and the Profiles. Each component plays a critical role in helping organizations manage their cybersecurity risks effectively.

1. Framework Core

At the heart of the NIST Cybersecurity Framework is the Framework Core. The Framework core provides a set of desired cybersecurity activities and outcomes using common language that is easy to understand. The Core is not a checklist of actions to perform; it presents key cybersecurity outcomes identified by industry as helpful in managing cybersecurity risk.

It comprises five concurrent and continuous functions that are essential for a robust cybersecurity posture:

• Identify: This function helps organizations develop a comprehensive understanding of their environment to manage cybersecurity risk to systems, assets, data, and capabilities. Key activities include asset management, business environment, governance, risk assessment, and risk management strategy.
• Protect: This function focuses on the development and implementation of appropriate safeguards to ensure the delivery of critical infrastructure services. It includes identity management, authentication and access control, awareness and training, data security, information protection processes and procedures, maintenance, and protective technology.
• Detect: This function involves the development and implementation of activities to identify the occurrence of a cybersecurity event. Key activities include anomalies and events, security continuous monitoring, and detection processes.
• Respond: This function encompasses the development and implementation of activities to take action regarding a detected cybersecurity event. It includes response planning, communications, analysis, mitigation, and improvements.
• Recover: This function involves the development and implementation of activities to maintain plans for resilience and to restore any capabilities or services that were impaired due to a cybersecurity event. This includes recovery planning, improvements, and communications.

2. Implementation Tiers

The Implementation Tiers of the NIST Cybersecurity Framework provide context on how an organization views cybersecurity risk and the processes in place to manage that risk. The Tiers range from Partial (Tier 1) to Adaptive (Tier 4) and describe an increasing degree of rigor and sophistication in cybersecurity risk management practices.

3. Profiles

A Profile represents the alignment of an organization’s cybersecurity activities with its business requirements, risk tolerance, and resources. Essentially, Profiles are used to describe the current state (“Current Profile”) and the desired state (“Target Profile”) of an organization’s cybersecurity practices.

Creating a Current Profile

A Current Profile captures the organization’s existing cybersecurity posture. This involves assessing the current implementation of the Core’s categories and subcategories. The Current Profile provides a snapshot of the organization’s present cybersecurity state, highlighting existing strengths and identifying areas that need improvement.

Creating a Target Profile

A Target Profile, on the other hand, outlines the desired outcomes that an organization aims to achieve to improve its cybersecurity posture. This involves selecting the categories and subcategories from the Framework Core that best align with the organization’s objectives and risk management strategy. The Target Profile serves as a benchmark for where the organization wants to be in terms of cybersecurity.

Using Profiles to Bridge the Gap

The real power of Profiles lies in their ability to bridge the gap between the Current and Target Profiles. By comparing the two, organizations can identify specific areas where they need to enhance their cybersecurity practices. This process involves:

• Gap Analysis: Comparing the Current Profile with the Target Profile to identify discrepancies and areas needing improvement.
• Prioritization: Based on the gap analysis, organizations can prioritize their cybersecurity initiatives, focusing on the most critical areas first.
• Action Plans: Developing detailed action plans to address the identified gaps. These plans should outline the steps needed to move from the Current to the Target Profile.
• Implementation and Monitoring: Executing the action plans and continuously monitoring progress to ensure that cybersecurity practices are evolving towards the Target Profile.

The NIST Cybersecurity Framework offers numerous benefits for organizations looking to enhance their cybersecurity posture. It provides a comprehensive and flexible approach to managing and mitigating cyber risks, helping organizations identify, protect, detect, respond to, and recover from cyber threats.
