What Is the Map of Cybersecurity Domains?

The map of cybersecurity domains is a structured visualization of the different categories or “domains” within the field of cybersecurity. This map serves as a comprehensive guide to the varied responsibilities, knowledge areas, and skills that cybersecurity professionals need to secure digital infrastructures effectively. 

By dividing cybersecurity into specific domains, this map provides a clearer understanding of how each area contributes to the overall protection of digital assets, ranging from application security to risk management and threat intelligence.

Historically, this mapping has evolved significantly. The Map of Cybersecurity Domain 2021 set an important foundation, but as new cyber threats and technologies emerged, the need for updated frameworks became evident. 

This led to the Map of Cybersecurity Domains 2025, which integrates advancements in areas like cloud security, artificial intelligence (AI), and internet of things (IoT) security. 

This updated map offers a more holistic and modernized view of cybersecurity, addressing gaps that were previously unaccounted for and refining existing domains to be more relevant to today’s cyber industry.

The purpose of a cybersecurity domain map goes beyond mere categorization. It helps organizations develop strategic plans, align security practices with industry standards, and ensure comprehensive risk management. 

For professionals, it serves as a “career map for cybersecurity,” guiding them on which areas to focus on for skill-building and career advancement. For businesses, it provides a foundation for implementing security measures, training employees, and meeting compliance standards.

Core Cybersecurity Domains

Understanding the core cybersecurity domains is essential for grasping the full scope of what cybersecurity professionals must address in their roles. The map of cybersecurity domains provides a visual framework that organizes the vast cybersecurity space into manageable focus areas. 

These domains represent the broad categories of security knowledge that professionals must develop expertise in, and they help guide organizations in creating comprehensive cybersecurity policies and strategies.

The Cybersecurity Domains List includes several critical domains that have become standard in industry practices. Some of the most prevalent domains in cybersecurity today include:

1. Application Security: Application security focuses on protecting software applications from cyber threats, vulnerabilities, and unauthorized access. This includes practices such as secure software development, security testing, and threat modeling. 

As businesses rely more heavily on digital applications, securing these platforms is increasingly crucial.

2. Risk Management: Effective risk management practices involve identifying, assessing, and mitigating risks that could potentially harm an organization’s operations or assets. 

This domain covers both cybersecurity risk assessment and enterprise risk management (ERM). Risk management helps organizations understand and prioritize cybersecurity risks in alignment with business objectives.

3. Governance: Governance encompasses the policies, procedures, and frameworks that define how cybersecurity is managed within an organization. It includes security governance, compliance with regulatory requirements, and the creation of an organizational culture that prioritizes security across all levels of operations.
4. Threat Intelligence: This domain involves gathering, analyzing, and acting on information related to cyber threats. By staying informed about the latest threats, organizations can take proactive measures to defend against potential attacks. 

Threat intelligence can be both internal (from within the organization) and external (from external sources).

5. Security Operations: Security operations refer to the day-to-day tasks and activities involved in monitoring and maintaining the security posture of an organization. 

This domain includes incident response, monitoring for suspicious activity, vulnerability management, and maintaining security infrastructure like firewalls and intrusion detection systems (IDS).

6. Identity and Access Management (IAM): IAM ensures that only authorized users have access to critical systems and data within an organization. This domain includes practices such as authentication, authorization, and managing user identities, ensuring that sensitive information is protected from unauthorized access.
7. Incident Response and Recovery: This domain involves responding to and managing security incidents, such as data breaches or cyberattacks. The goal is to limit damage, recover from the incident, and ensure that measures are in place to prevent future occurrences.

These core domains, along with others such as Physical Security, Cloud Security, and User Education, play a pivotal role in ensuring the cybersecurity framework of an organization is comprehensive and robust. 

The Map of Cybersecurity Domains offers an easy way to visualize these areas and recognize the interconnections between them. Understanding these domains helps organizations safeguard their operations and provides cybersecurity professionals with clear areas to specialize in as they develop their careers.
