Tactics
In the meticulously structured ecosystem of the MITRE ATT&CK Framework, tactics stand as the fundamental pillars, articulating the overarching objectives or "whys" behind an adversary's actions within the cyber-attack life-cycle. Each of these tactics is intricately aligned with a specific phase of this life-cycle, ranging from the preliminary steps of gaining information and preparing for an attack, to the final stages of achieving the intended impact on the target. The framework enumerates 12 core tactics, each embodying a distinct facet of a cyber operation's strategic intent:
Reconnaissance: This tactic involves the deliberate collection of information about the target to inform future attack strategies. Adversaries engage in probing for vulnerabilities, identifying valuable assets, and understanding security measures to tailor their attack methods more effectively.
Resource Development: Here, adversaries focus on creating, purchasing, or compromising resources that will support the execution of their attacks. This could involve setting up infrastructure such as command and control servers (C2), acquiring tools like malware and exploits, or even creating personas for social engineering campaigns.
Initial Access: The linchpin of any cyber-attack, this tactic encompasses the various methods adversaries employ to breach the digital perimeter of a target network. Techniques under this category can range from phishing campaigns to exploiting vulnerabilities in public-facing applications.
Execution: Execution refers tot he methods used by adversaries to run malicious code on a victim's system, which is pivotal for the deployment of payloads, escalation of privileges, or lateral movement withing the network.
Persistence: Ensuring continuous access to a compromised system is the crux of this tactic. Adversaries implement methods to maintain their foothold with a network, even in the face of system reboots, updates, or changes in security measures.
Privilege Escalation: Gaining higher-level permissions is often necessary for adversaries to access restricted data, modify system configurations, or execute privileged commands, thereby expanding their control over the compromised environment.
Defense Evasion: This tactic involves techniques designed to avoid detection by security systems, obfuscate malicious activities, and maintain the integrity of the attack by circumventing security features and evading analysis.
Credential Access: Accessing or stealing authentication credentials is a critical step for adversaries and threat actors, allowing them to masquerade as legitimate users, escalate their access rights, and explore the network with fewer restrictions.
Discovery: To navigate a network effectively and identify valuable targets, adversaries must understand the environment they've infiltrated. This tactic covers the techniques used to map out systems, services, and data within a network.
Lateral Movement: This involves moving from one system to another within a network, often leveraging escalated privileges or stolen credentials, to extend the breach's scope and reach high-value targets.
Collection: The focus here is on gathering data of interest from the target network, which may include sensitive documents, credentials, or proprietary information, in preparation for exfiltration.
Exfiltration: The act of stealing data marks this tactic, where adversaries employ various methods to transfer the collected information from the target network to a location they control, often stealthily to avoid raising alarms.
Impact: The ultimate goal of some cyber-attacks is to manipulate, interrupt, or outright destroy systems and data, thereby achieving the desired detrimental effect on the target, be it for financial gain, espionage, or sabotage
Each of these tactics is further decomposed into techniques and sub-techniques in the framework, providing a granular view of the specific actions adversaries might take to achieve their objectives. This detailed breakdown not only aids in the comprehension of potential attack paths but also in the formation of targeted defensive strategies to counteract or mitigate these actions.
Techniques
Within the complex fabric that makes up the MITRE ATT&CK Framework, techniques have a crucial role. Techniques describe "how" a tactic is executed, providing specifics on the actions an adversary takes to achieve their objective. Each technique can have one or more sub-techniques, offering even more detail into the adversary's methods. These techniques often provide a granular exposition of the specific actions, maneuvers, and operational practices employed by threat actors as they navigate through the various phases of an attack. The framework meticulously categorizes these techniques under corresponding tactics, providing a clear and systematic roadmap of the potential steps an adversary might take to fulfill their strategic goals.
Each technique within the framework is elaborated upon with precision, outlining the operational nuances and tactical intricacies that define a particular method of attack. This level of detail is instrumental in enabling cybersecurity professionals to dissect and comprehend the multifaceted nature of cyber threats, extending beyond general tactics to the precise execution strategies employed by adversaries.
To further enhance this granularity, the framework introduces the concept of sub-techniques. These sub-techniques delve deeper into the specifics of a technique, dissecting it into more detailed components and variants. This hierarchical structure allows for an even more refined analysis of adversary behavior, capturing the subtle variations and tactical adjustments that might be made in different contexts or against different targets.
For instance, taking "Initial Access" as a tactical category, the technique of "Spear Phishing" is identified as a common method used by adversaries to gain entry into a network. The framework then breaks down "Spear Phishing" into sub-techniques that details the various implementations of this tactic, such as the delivery of malicious payloads through email links, the use of deceptive attachments designed to exploit vulnerabilities, or the employment of social engineering tactics to manipulate the recipient into compromising their own security. Each sub-technique is accompanied by examples, indicators, and mitigations, providing a comprehensive understanding of how such attacks are orchestrated and how they can be thwarted.
This layered approach to detailing techniques and sub-techniques equips cybersecurity professionals with the insights necessary to identify and counteract specific adversarial actions effectively. By understanding not just the broader tactic but the precise techniques and even sub-techniques employed, defenders can tailor their security measures and responses to the nuanced challenges posed by sophisticated cyber threats, enhancing their ability to protect their organizations from potential breaches.
