Exam CAS-005 topic 1 question 72 discussion

✅ C. Covert channel analysis Covert channels are methods used to transfer information in a way that violates a system's security policy. These channels can be used to sneak data across domain boundaries without triggering standard detection mechanisms. Covert channel analysis involves identifying and evaluating these hidden paths of communication, which is exactly what the question is asking about. Why the other options are incorrect: A. Machine-learning statistical analysis Useful for anomaly detection and predictive analysis, but not specific to detecting covert or hidden transmission channels. B. Fuzz testing Primarily used to find software vulnerabilities and bugs by sending random data to inputs. It’s not aimed at identifying how data controls can be bypassed stealthily. D. Protocol analysis Involves examining network protocols for proper behavior or misconfigurations, but it does not specifically target hidden or covert data transmissions.
