Threat-informed defense is a strategic approach to cybersecurity that combines threat intelligence with traditional security measures and threat analysis. It enables organizations to proactively identify potential threats, anticipate malicious attacks, and take proactive steps to mitigate risk. In this article “Enhancing Cybersecurity with Threat-Informed Defense”, we will explore the concept of threat-informed defense, its advantages, and how organizations can implement it to enhance their cybersecurity posture.

What is Threat-Informed Defense?

Threat-Informed Defense (TID) is a systematic application of deep understanding of adversary tradecraft and technology to improve defenses. It goes beyond basic IT security building blocks and incorporates threat intelligence, configuration management, vulnerability management, and deployment of essential controls. TID is both a set of practices and a way of thinking that helps organizations build a strong security foundation and prioritize their resources based on the threats they face. Enhancing cybersecurity with threat-informed defense is crucial for building an effective cybersecurity strategy.

The Center for Threat-Informed Defense (The Center) is a leading research and development organization dedicated to advancing the art and practice of threat-informed defense globally. As a non-profit organization operated by MITRE Engenuity, The Center provides public resources and collaborates with industry, academia, and other stakeholders to develop new methods, tools, and best practices for threat-informed defense. Their work focuses on collecting, analyzing, and disseminating threat intelligence, evaluating the effectiveness of different defense approaches, and integrating threat intelligence into existing security processes and systems.

The Advantages of Threat-Informed Defense

Threat-informed defense offers several advantages that can significantly enhance an organization’s cybersecurity posture.

  • Freely-Available Resources

Through organizations like MITRE and The Center for Threat-Informed Defense, businesses of all sizes have access to freely available tools and resources to implement a threat-informed defense strategy. For example, the MITRE ATT&CK Matrix provides a threat-oriented framework for understanding, preparing for, and responding to cyber threats. The Center releases public research, guides, and case studies on practical applications of MITRE ATT&CK® that organizations can follow.

  • Improved Efficiency and Effectiveness

By focusing on the threats that are most likely to be encountered, threat-informed defense enables organizations to prioritize their resources and implement more effective defenses. It helps avoid wasting resources on ineffective or unnecessary measures by basing defenses on a detailed understanding of the threats they face.

  • Risk-Based Cybersecurity

Threat-informed defense aligns with a risk-based cybersecurity strategy, which involves evaluating and prioritizing risks to allocate resources effectively and manage risk. By understanding specific threats and their tactics, techniques, and procedures (TTPs), organizations can design and implement defensive measures that are tailored to their unique risk landscape.

  • Improved Decision-Making

Threat intelligence provides valuable insights into the tactics and techniques used by threat actors. By understanding how threat actors operate, organizations can develop more effective response strategies and optimize their security posture. Threat-informed defense enables informed decision-making at both strategic and daily operational levels.

  • Improved Resilience

By proactively anticipating and preparing for potential threats, organizations can enhance their resilience to attacks and other security incidents. Threat-informed defense equips organizations with the knowledge and tools to detect, mitigate, and recover from cyber threats effectively.

Implementing Threat-Informed Defense

Implementing a threat-informed defense strategy involves several steps that organizations can follow to strengthen their cybersecurity defenses.

Step 1: Identify Relevant Threat Types

Organizations need to identify the types of threats that could potentially affect them. This includes both internal and external threats. Staying up to date with the latest attacks targeting similar organizations in their industry and geography can help organizations identify relevant threats such as ransomware, phishing, data breaches, and insider threats. The MITRE ATT&CK® matrix can assist in identifying and categorizing these threats.

Step 2: Monitor Your Network

Active monitoring of the network is crucial to identify any malicious activity. By monitoring the network, organizations can detect potential threats and associated tactics, techniques, and procedures (TTPs). It is essential to mitigate and remediate any active compromises promptly. Prioritizing the addressing of techniques that adversaries have successfully used to compromise the organization can help strengthen defenses.

Step 3: Map Your Security Stack to Adversarial TTPs

Organizations need to assess how their existing security tools address the adversarial techniques identified in steps 1 and 2. The MITRE ATT&CK® Matrix and resources provided by The Center can guide organizations in addressing these threats effectively. It is crucial to identify any gaps in defenses and areas where additional defense-in-depth measures are necessary.

Step 4: Make Appropriate Adjustments to Your Cybersecurity Stack

Based on the assessment of existing security tools, organizations should invest in areas where they are most vulnerable. This may require making improvements to existing defenses or investing in new cybersecurity solutions. It is essential to verify that existing cybersecurity tools deliver on their promises and make adjustments to the budget if critical vulnerabilities cannot be covered under the existing strategy.

Step 5: Continuous Improvement

Implementing threat-informed defense is an ongoing process. Organizations should continuously monitor and assess their network infrastructure for internal threats and vulnerabilities. It is therefor crucial to stay informed about external developments in the threat landscape and adapt defenses accordingly. Regularly reviewing and updating the threat-informed defense strategy ensures its effectiveness and relevance over time.

Complementing and Empowering Threat-Informed Defense

To enhance the effectiveness of threat-informed defense, organizations can leverage additional strategies and practices.

  • Test and Validate the Effectiveness of the Strategy

Regularly testing and validating the threat-informed defense strategy is crucial to identify weaknesses and areas for improvement. Organizations can conduct simulated attacks or penetration tests to identify vulnerabilities and assess the effectiveness of their security controls. Automated testing can emulate adversary behaviors and validate the proper configuration of defenses.

  • Review and Update the Strategy

As the threat landscape evolves, it is important to periodically review and update the threat-informed defense strategy. This involves adjusting the focus of the strategy based on new or emerging threats and making changes to defensive measures accordingly. Regular reviews ensure that the strategy remains effective and aligned with the evolving threat landscape.

  • Integrate Threat Intelligence

Incorporating high-quality, timely, and relevant threat intelligence into the threat-informed defense strategy can provide valuable insights and enhance proactive defense capabilities. Subscribing to threat intelligence feeds, participating in information-sharing initiatives, and establishing relationships with trusted sources of intelligence can help organizations stay ahead of threats.

  • Implement Strong Security Controls

A strong security posture is essential for effective threat-informed defense. Organizations should implement robust security controls, including firewalls, intrusion detection and prevention systems, access controls, employee awareness training, and data loss prevention measures. These controls protect against external threats and mitigate the risk of internal threats.


Implementing a threat-informed defense strategy is crucial for organizations looking to enhance their cybersecurity posture in today’s threat landscape. By combining threat intelligence, proactive monitoring, and a risk-based approach, organizations can proactively identify and mitigate potential threats.
