What is the term for a cybersecurity technique that aims to confuse a program or person analyzing a system?

The term that best describes a cybersecurity technique aimed at confusing a program or person analyzing a system is associated with the concept of obfuscation. While the choice identified may seem plausible, the correct focus is on techniques that deliberately make systems or data difficult to interpret or analyze.

Encryption is a process used to secure data by converting it into a format that cannot be easily understood without the proper decryption key; its purpose is primarily to protect confidentiality rather than to confuse.

Intrusion Detection refers to monitoring a system or network for signs of malicious activity and does not aim at obfuscation but rather at detection and response.

Data Masking involves altering identifiable information within a database or system to protect sensitive data while maintaining usability. It serves to protect data rather than confuse an analysis.

A "Layer of Protection” could imply an overall security strategy, involving multiple defense mechanisms, but it does not specifically relate to the act of confusing analysis.

Considering these context clues, the aim of techniques like obfuscation relates closely to how security measures can deliberately confuse potential analyzers of a system, thereby protecting sensitive information or making reverse engineering more difficult.
