Understanding the MITRE ATT&CK Framework

Understanding the MITRE ATT&CK Framework

The MITRE ATT&CK framework is a publicly available knowledge base of adversary tactics and techniques based on real-world observations. It was originally developed by the MITRE Corporation to help security professionals better understand how attackers operate and how to detect or mitigate their activities.

What does ATT&CK stand for?

Adversarial Tactics, Techniques, and Common Knowledge. The framework catalogs specific behaviors (techniques) that adversaries use to achieve goals (tactics), along with references to real incidents where those behaviors were observed.

Why is ATT&CK important?

1. Threat Modeling – Security teams can use ATT&CK to map out how an attacker might progress through the network and identify gaps in defenses.
2. Detection Engineering – By aligning detection rules with ATT&CK techniques, analysts gain better visibility into adversary behavior.
3. Assessment and Reporting – ATT&CK provides a common language to describe attacker actions, making incident reports consistent and easier to share.

Core Components

The framework is organized into a matrix of tactics (the columns) and techniques (the rows). Key categories include:

• Initial Access – How an attacker first breaks into a network. Common techniques here include spearphishing and exploiting public-facing applications.
• Privilege Escalation – Methods used to gain higher-level permissions once inside a system, such as exploiting software vulnerabilities or bypassing access controls.
• Lateral Movement – Techniques that allow an attacker to move from one host to another, often using valid credentials or remote services like SMB or RDP.
• Command and Control – Ways attackers maintain communication with compromised systems, often through malicious domains, IP addresses, or DNS tunneling.

In addition, each technique can be broken down into sub-techniques that provide more granular descriptions. For example, Credential Dumping under the Credential Access tactic includes sub-techniques for obtaining passwords from memory, the registry, or other sources.

Putting ATT&CK into Practice

To get started with ATT&CK:

1. Map existing detections – Review your current security tools and map alerts to ATT&CK techniques. This highlights coverage gaps.
2. Simulate attacker behavior – Use tools like the open-source CALDERA platform or manual red team exercises to reproduce common techniques.
3. Prioritize defenses – Focus on techniques most relevant to your environment. For instance, organizations with many Windows systems should prioritize coverage for PowerShell abuse and Credential Dumping.

Continual Updates

MITRE updates the framework regularly based on new threat research. Keeping an eye on those updates ensures your defenses remain aligned with the latest adversary behaviors.

Ultimately, the MITRE ATT&CK framework empowers security teams with a structured approach to understanding how attackers operate. By integrating ATT&CK into your security program, you can improve detection, streamline incident response, and better communicate threat information across your organization.
