MITRE ATT&CK Framework

admin

OVERVIEW

The MITRE ATT&CK framework is a comprehensive matrix of tactics, techniques, and procedures (TTPs) used by cyber adversaries to carry out attacks. It provides a common language and a structured way to describe and categorize cyber adversary behavior. Here’s an overview of the key components of the MITRE ATT&CK framework:

1. Tactics

Tactics represent the “why” of an ATT&CK technique. They are the adversary’s tactical goals during an attack. The tactics are organized into the following categories:

  • Initial Access: Techniques used to gain an initial foothold within a network.
  • Execution: Techniques that result in adversary-controlled code running on a local or remote system.
  • Persistence: Techniques that adversaries use to maintain their foothold.
  • Privilege Escalation: Techniques that adversaries use to gain higher-level permissions on a system or network.
  • Defense Evasion: Techniques used to avoid detection or evade defenses.
  • Credential Access: Techniques used to steal credentials like account names and passwords.
  • Discovery: Techniques used to gain knowledge about the system and internal network.
  • Lateral Movement: Techniques that adversaries use to move through a network.
  • Collection: Techniques used to gather information and files.
  • Command and Control: Techniques used to communicate with compromised systems.
  • Exfiltration: Techniques used to steal data from the network.
  • Impact: Techniques that manipulate, interrupt, or destroy systems and data.

2. Techniques

Techniques describe the “how” an adversary achieves a tactical goal. Each technique represents a specific method that an attacker may use to achieve a specific tactic. Techniques can have sub-techniques that provide a more granular level of detail. For example:

  • Phishing (T1566): Using deceptive emails to gain access to user credentials or deliver malware.
    • Spearphishing Attachment (T1566.001): Sending emails with malicious attachments.
    • Spearphishing Link (T1566.002): Sending emails with links to malicious websites.

3. Procedures

Procedures are the specific implementation of techniques or sub-techniques by adversaries. These are often highly specific and tailored to particular targets or environments. Procedures detail the exact commands or code used in the attack.

4. Use Cases of MITRE ATT&CK

MITRE ATT&CK can be used for various purposes, including:

  • Threat Intelligence: Understanding and mapping known adversary behaviors.
  • Detection and Response: Developing detection rules based on ATT&CK techniques.
  • Security Assessment: Conducting red team exercises and penetration testing.
  • Adversary Emulation: Simulating specific adversaries to test defenses.

5. Application in Cyber Defense

The MITRE ATT&CK framework is used extensively in cybersecurity for enhancing defenses:

  • SOC Teams: Use ATT&CK to prioritize alerts and refine detection capabilities.
