Hi, and welcome back. In this lesson, we explore gap analysis in the context of cybersecurity. We will explain what a gap analysis is, why it is important, and its main components.

A gap analysis is a systematic process used to assess an organization’s current cybersecurity measures, identify areas of weakness, and develop strategies to bridge the gap between the current state and the ideal state. In simple terms, we first define what a perfect cybersecurity setup should look like if resources were unlimited. Next, we evaluate our current situation and finally, determine the gap between these two states. This approach helps ensure that an organization’s cybersecurity posture aligns with industry standards, best practices, and regulatory requirements, effectively reducing risks.
The image illustrates a gap analysis concept, showing two people bridging a gap between the "Current State" and "Desired State" with an "Action Plan."
Conducting a gap analysis provides a clear pathway for enhancing your organization’s security measures by identifying specific vulnerabilities and areas for improvement.
Next, we dive into one of the most common frameworks used as a basis for cybersecurity gap analysis: the NIST Cybersecurity Framework. This framework offers a comprehensive approach to managing and reducing cybersecurity risks through five core functions: Identify, Protect, Detect, Respond, and Recover.

Using the NIST Cybersecurity Framework

The NIST Cybersecurity Framework is built on standards, guidelines, and best practices that help organizations manage cybersecurity risks systematically. Its structure, organized around five key functions, enables organizations to effectively implement and enhance security measures. Let’s explore each function in detail:

​
1. Identify

The Identify function involves understanding your organization’s critical systems, assets, data, and associated risks. This foundational step in a cybersecurity gap analysis requires you to:
  • Inventory all assets (hardware, software, data, etc.) to ensure that nothing critical is overlooked.
  • Identify current security policies and procedures for subsequent comparison with industry best practices.
The image is a diagram with a shield shape containing four icons labeled Data, Software, Hardware, and Network, under the heading "Identify."
By assessing your current security infrastructure, you establish a baseline that helps measure progress towards your ideal cybersecurity state.
The image features an icon with a checkmark and a key, labeled "Security policies and procedures," under the heading "Identify."

2. Protect

The Protect function focuses on implementing safeguards to ensure the delivery of critical infrastructure services. In this phase, you should:
  • Evaluate current access control mechanisms and enforce strong authentication and authorization protocols.
  • Incorporate practices such as multi-factor authentication (MFA) and role-based access controls.
  • Assess data protection measures like encryption, Data Loss Prevention (DLP), and secure data storage practices.
  • Review training and awareness programs, alongside regular maintenance plans including security patching and software updates.
The image outlines three key aspects of data protection: Authentication & Authorization, Access Control Mechanisms, and Data Security, each with brief descriptions.

​
3. Detect

The Detect function is all about implementing the necessary activities to identify cybersecurity events as they occur. Key initiatives include:
  • Establishing real-time monitoring and alerting mechanisms.
  • Deploying automated tools that continuously monitor your network and systems.
  • Defining what constitutes normal activity in order to effectively detect anomalies or intrusions.
The image shows three labeled sections: "Incident Identification," "Real-time monitoring," and "Alerting," each with corresponding icons. It appears to be part of a process or system related to detection.

​
4. Respond

The Respond function involves setting up and testing incident response plans to manage cybersecurity breaches effectively. This includes:
  • Reviewing and refining the efficiency of current incident response plans.
  • Developing and practicing detailed procedures for incident response and communication to ensure a coordinated reaction when a breach is detected.
The image shows two labeled sections: "Incident Response" with an icon of speech bubbles and arrows, and "Communication" with an icon of people and speech bubbles.

​
5. Recover

The Recover function is dedicated to restoring any capabilities or services that are impaired following a cybersecurity incident. Best practices in this phase include:
  • Developing a resilient recovery plan that is regularly reviewed and improved.
  • Ensuring that recovery strategies remain adaptable to address new and emerging cyber threats.

​
Conclusion

In this lesson, we used the NIST Cybersecurity Framework as an example to illustrate the process of a gap analysis. The primary goal of a gap analysis is to identify and address cybersecurity vulnerabilities by comparing your ideal state with your current state. Although the NIST framework is widely adopted, other frameworks may be used depending on regional or organizational preferences—the process remains fundamentally the same. Conducting a thorough gap analysis is a powerful strategy to bolster your organization’s cybersecurity defenses. By systematically evaluating the functions of Identify, Protect, Detect, Respond, and Recover, organizations can significantly reinforce their security posture against evolving cyber threats.
