In the event of a cyberattack, there many factors to consider when debating on how to respond. Is it ethical to hack back in retaliation? Originally presented at the IEEE Symposium on Technologies for Homeland Security, researchers from Purdue University have outlined two potential frameworks for approaching the decision of whether to hack back. 

Hacking Back: To Do or Not To Do?

The Law Enforcement Approach

This approach views hacking attacks as criminal acts, where ethical decisions are based on United States laws, applicable international laws/treatises, and non-binding international standards and guidelines.

The Military Style Approach
