The MITRE ATT&CK Matrix: Understanding the Framework’s Structure

At the core of the MITRE ATT&CK Framework is its detailed matrix of tactics, techniques, and procedures (TTPs), a structured categorization that provides a granular understanding of adversary behaviors. This section will elucidate the framework’s structure, offering insights into how its components interlink to offer a comprehensive picture of cyber threats.

Tactics

Tactics represent the “why” of an adversary’s actions—their objectives during an attack. Each tactic within the framework corresponds to a specific goal that the adversary aims to achieve, such as gaining initial access, executing commands, or exfiltrating data. Understanding these tactics allows cybersecurity professionals to anticipate what an attacker might do next, informing strategic defensive measures.

The MITRE ATT&CK Framework organizes these objectives into a series of categories, each representing a stage in the attack lifecycle. From initial access and execution to privilege escalation and exfiltration, tactics offer a lens through which to view the adversary’s intentions. Recognizing these objectives is pivotal for defenders, as it guides the development of targeted defensive strategies to thwart the attackers’ plans.

  1. Reconnaissance: The collection of information used to plan future attacks. This includes gathering data on the target’s personnel, infrastructure, and digital presence to identify vulnerabilities and plan entry points.
  2. Resource Development: The creation and management of resources used in attacks, such as acquiring domain names, developing malware, and establishing infrastructure for operations.
  3. Initial Access: The methods attackers use to gain an entry point into a network. Techniques under this tactic include phishing, exploiting public-facing applications, and using valid accounts.
  4. Execution: The execution of code to carry out actions on the target system, such as running malicious scripts or exploiting vulnerabilities to execute arbitrary code.
  5. Persistence: The techniques used by attackers to maintain their foothold within a network across reboots, changed credentials, and other interruptions that could cut off their access.
  6. Privilege Escalation: Methods used to gain higher-level permissions on a system or network. Common techniques include exploiting system vulnerabilities and manipulating access tokens.
  7. Defense Evasion: Techniques designed to avoid detection by security measures, such as obfuscating malicious code, disabling security software, and using encryption to hide command and control traffic.
  8. Credential Access: The strategies used to steal account names and passwords, including credential dumping, input capture, and exploiting system or service vulnerabilities.
  9. Discovery: The actions taken to gain knowledge about the system and internal network. Attackers may catalog software installations, understand security policies, and enumerate system and network resources.
  10. Lateral Movement: Techniques that enable an attacker to move through a network, gaining access to additional systems to control remote systems, often using stolen credentials.
  11. Collection: The gathering of data of interest to the attacker’s objectives. This may involve capturing screenshots, keylogging, or collecting data stored in the cloud.
  12. Command and Control (C2): The mechanisms used to maintain communication with the compromised system, allowing the attacker to control the system remotely, exfiltrate data, and deploy additional tools.
  13. Exfiltration: The methods used to steal data from the target network. Techniques can include transferring data over the command and control channel, using a web service, or physical means.
  14. Impact: The tactics aimed at disrupting, destroying, or manipulating information and systems to affect the target’s operations. This includes data destruction, defacement, and denial of service attacks.

Techniques

Techniques describe “how” the adversaries achieve their objectives. For each tactic, the framework lists various techniques that adversaries might employ. For instance, under the tactic of “Initial Access,” techniques could include spear-phishing emails or exploiting public-facing applications. By cataloging these techniques, the framework offers a playbook of potential attack methods, enabling defenders to tailor their defenses to the most likely threats.

For each tactic, there are multiple techniques that an adversary might employ, reflecting the diverse array of tools and methods at their disposal. Understanding these techniques is critical for cybersecurity professionals, as it enables them to identify potential attack vectors and implement appropriate safeguards.

The MITRE ATT&CK Framework catalogs a vast array of techniques that adversaries use to achieve their objectives throughout the attack lifecycle. While the relevance of specific techniques can vary depending on the context, environment, and targets, there are several that are frequently observed across a wide range of incidents.
