CompTIA Security+ Exam Prep

Answer: D - Differential power analysis, electromagnetic analysis, and side-channel attacks are all types of attacks that have the goal of uncovering sensitive information without wanting to compromise any type of flaw or weakness. A noninvasive attack is one in which the attacker watches how something works and how it reacts in different situations instead of trying to “invade” it with more intrusive measures. Differential power analysis examines the power emissions released during processing, while electromagnet analysis examines the frequency emitted. These are commonly used for data collection. Attackers monitor and capture the analog characteristics of all supply and interface connections and any other electromagnetic radiation produced by the processor during normal operation.
