CERTIFIED-IN-CYBERSECURITY Question #271: Real Exam Question with Answer & Explanation
The correct answer is B: A passive, noninvasive attack to observe the operation of a device. A side-channel attack is a type of security attack where the attacker gains information from the physical implementation of a system, rather than exploiting software vulnerabilities (see ISC2 Study Guide, Module 2, under Types of Threats). This can include observing the power con
Question
What is a side-channel attack?
Options
- AAn attack with the goal of gaining access to a target system through the use of a falsified identity
- BA passive, noninvasive attack to observe the operation of a device
- CAn attack that involves numerous unsuspecting secondary victim systems
- DAn attack that attempts to misdirect legitimate users to malicious websites
Explanation
A side-channel attack is a type of security attack where the attacker gains information from the physical implementation of a system, rather than exploiting software vulnerabilities (see ISC2 Study Guide, Module 2, under Types of Threats). This can include observing the power consumption, electromagnetic leaks, timing information, acoustic signals, and even the amount of heat a device produces. By analyzing this data, attackers can potentially deduce sensitive information about the system, such as cryptographic keys. The other options provided do not accurately describe side-channel attacks
