Hyökkäyspuumallit, known in English as attack trees, are a visual modeling technique used to represent and analyze potential threats to a system. They are hierarchical diagrams that break down an attacker's goal into a series of sub-goals and actions that can be combined using logical operators like AND and OR. The root of the tree represents the attacker's ultimate objective, such as gaining unauthorized access to sensitive data or disrupting a critical service.

Each node in the tree represents either a goal or a specific attack action. Leaf nodes represent the most basic, atomic actions an attacker might take, such as exploiting a known vulnerability, performing a social engineering attack, or gaining physical access. Intermediate nodes represent more complex goals that can be achieved by satisfying the sub-goals represented by their children. The logical operators (AND, OR) dictate how these sub-goals must be met. An AND node means all sub-goals must be achieved, while an OR node means at least one sub-goal needs to be achieved.

Attack trees are valuable for security professionals and system designers as they provide a structured way to think about potential attack vectors. By visualizing the different paths an attacker might take, organizations can better identify vulnerabilities and prioritize security measures. The process of constructing an attack tree can also help uncover unforeseen attack scenarios and improve the overall security posture of a system. They are particularly useful in security risk assessments, threat modeling, and penetration testing.
