Which term describes a series of actions that adversaries perform to achieve specific outcomes?

The term that best describes a series of actions that adversaries perform to achieve specific outcomes is "tactics." In the context of cybersecurity and attack scenarios, tactics refer to the overarching goals or objectives that an adversary aims to accomplish during a cyber operation. These can involve activities such as establishing a foothold, executing attacks, or exfiltrating data.

Tactics are part of a broader framework that often includes techniques and procedures. Techniques provide more detailed descriptions of how specific tactics are implemented, showing the methods adversaries might use to accomplish their objectives. While strategies imply a more comprehensive plan or approach to achieve long-term goals, they are less focused on the individual actions taken in a specific context than tactics are.

This distinction highlights why "tactics" is the most appropriate choice, as it captures the immediate actions that contribute directly to specific outcomes in adversarial behavior.
