MITRE ATT&CK Framework: What It Is and Why It Matters

Security fragmentation is one of the biggest issues facing cybersecurity leaders today. The threat landscape is evolving rapidly – the share of organizations that reported an AI-related security incident is 97%, according to IBM’s Cost of a Data Breach Report 2025 – yet no rules addressing these threat actors and their operations exist. There isn’t even a common language in place, which makes discussing cyber-attacks almost as hard as stopping them.

There’s no doubt that experts can communicate among themselves, but security teams alone don’t prevent cyber attacks. It takes companywide awareness and cohesion, and business units across organizations need to be ready to respond. 

So, what happens when an attack does hit? Today, over half of all breaches incorporate hacking, which means threat actors are as sophisticated as they are numerous. To discuss, prepare for, and ultimately respond to these advanced attacks, organizations are moving towards cybersecurity frameworks – documents that outline the policies, procedures and processes to follow in the case of a breach.

MITRE ATT&CK, a globally accessible knowledge base of adversary tactics and techniques based on real-world observations, seems to be cementing its place as the "lingua franca" of modern cybersecurity and a foundational tool for threat detection. Using ATT&CK, it’s possible to identify security weaknesses before you find out the hard way.

How MITRE ATT&CK Compares to Other Cybersecurity Frameworks

When it comes to guidance on building detection and response programs, MITRE ATT&CK trumps traditional frameworks such as the Diamond Model, which lacks technical depth, and Lockheed Martin’s Cyber Kill Chain, which offers little from the attacker's perspective. At Immersive, we believe to keep pace you need to learn like hackers – and this is where MITRE ATT&CK, which has a strong adversarial focus, can help.

Unlike defenders who must secure their entire surface of attack, hackers need to find just one weakness to penetrate a network. This first-mover advantage means that, historically, attackers have had control. However, MITRE ATT&CK is leveling the playing field with its numerous tactics, techniques and procedures (TTPs), which are based on real-world observation.

Thanks to this basis in real life, MITRE ATT&CK provides unrivaled detail regarding the ways threat actors can run an attack, starting with the initial access phase. It organizes the building blocks of an attack so that organizations can visualize exactly what adversaries could achieve on their network, making it easier to put relevant defenses in place. So, when a business identifies an attacker on its network, it has a ready-made list of responses for mitigation – meaning less time wasted filling in gaps.

Key Benefits of the MITRE ATT&CK Framework

One of MITRE ATT&CK’s biggest wins is that it can evaluate the capabilities of security technology. This means organizations can identify which tech covers the risks most relevant to them before splashing out. Alternatively, if their existing tech doesn’t cover a certain area, they can do something about patching that weakness – like upskilling staff.

MITRE ATT&CK can integrate with threat intelligence to drive security, too. When a new threat is discovered, for example, the categories in the framework enable security teams to respond or confirm current levels of protection.

How to Use MITRE ATT&CK to Measure and Develop Cyber Skills

While MITRE ATT&CK is primarily used to reduce cyber risk, it is also an excellent resource for cyber workforce development. At present, many training programs and certifications teach skills that are not grounded in real-world experience. And even if they are, they might not be particularly relevant to a specific organization’s needs or gaps. 

Immersive maps its cyber skills content against the MITRE ATT&CK framework, which enables organizations to see where their staff are proficient and where they are lacking. This means managers can take a proactive approach to developing the skills of their security teams, as they can visualize their business’s risk profile.

A healthcare organization, for example, might be at high risk from a certain APT group. The organization’s security team would do their research into the tactics that said group was using, and then begin ticking off skills against the MITRE ATT&CK framework. Any key missing skills could then be developed through Immersive. This is a focused way of learning that boosts the effectiveness of your cyber workforce.

How to Apply MITRE ATT&CK to Your Cyber Workforce

We have some useful resources that can help you start using ATT&CK to measure, validate, and visualize the human capabilities in your organization. Our short eBook on Aligning Cyber Skills to the MITRE ATT&CK Framework explains the framework and how it can be used to map tactics and techniques to skills.
