Advanced Cybersecurity Techniques / March 15, 2023

The MITRE ATT&CK framework is a valuable tool for organizations seeking to enhance their cybersecurity posture. By providing a comprehensive knowledge base of tactics and techniques employed by cyber attackers, the framework allows organizations to develop more effective incident response plans and threat intelligence strategies. Through this approach, organizations can gain a better understanding of the threat landscape, including the specific threats they face and how to defend against them.

One of the key features of the MITRE ATT&CK framework is its interactive visualization tool, the MITRE ATT&CK Matrix. This tool allows users to explore the tactics, techniques, and procedures used by attackers in detail. By using the Matrix, organizations can identify gaps in their security posture and develop more effective security measures. Compared to older frameworks like the Cyber Kill Chain and the Diamond model, which only focus on specific stages of an attack, the MITRE ATT&CK framework indexes all aspects of an attack from both the attacker and the defender’s perspective. With its widespread adoption, the MITRE ATT&CK framework has become the most widely adopted cybersecurity framework used today, providing a powerful tool for organizations to better understand and defend against cyber threats.

Understanding MITRE ATT&CK Tactics and Techniques

The MITRE ATT&CK framework is a comprehensive tool for understanding the tactics and techniques used by cyber adversaries. It breaks down the attack lifecycle into 14 tactics that are categorized based on the objectives of the attackers. These tactics include Reconnaissance, Resource development, Initial access, Execution, Persistence, Privilege escalation, Defense evasion, Credential access, Discovery, Lateral movement, Collection, Command and Control, Exfiltration, and Impact.

Each of these tactics encompasses a range of techniques that adversaries use to achieve their goals. For instance, techniques under the Execution tactic include code signing, DLL side-loading, and PowerShell, while techniques under the Persistence tactic include Registry Run Keys and Services. Adversaries may use different techniques depending on factors such as their skill sets, the configuration of the system they are attacking, and the availability of necessary tools.

The MITRE ATT&CK framework includes a total of 193 techniques and 401 sub-techniques identified for enterprises. For each technique, the framework provides detailed information, such as a description of how it works, the systems it pertains to, which known attacker groups use it, ways to mitigate its impact, and references to its use in the wild. By understanding the tactics and techniques used by adversaries, organizations can better assess their risk and develop more effective defenses. The MITRE ATT&CK Matrix is an invaluable tool for identifying gaps in an organization's security posture and developing a more robust security strategy.

Common Attack Techniques and Mitigation Strategies

One of the key benefits of using the MITRE ATT&CK framework is the ability to identify common attack techniques and develop strategies to mitigate them. By understanding how attackers operate, organizations can implement more effective defenses and reduce the risk of successful attacks.

For example, the Execution tactic includes techniques such as code signing, DLL side-loading, and PowerShell. To mitigate these techniques, organizations can use techniques such as code signing policies, whitelisting, and limiting access to PowerShell. Similarly, the Persistence tactic includes techniques such as Registry Run Keys and Services, which can be mitigated through methods such as removing unnecessary accounts and limiting the use of domain accounts.
