Final answer:
option a,An Intrusion Detection System (IDS) is most associated with the integrity tenet of the CIA triad, as it monitors for unauthorized changes or anomalies in network traffic.
Step-by-step explanation:
An Intrusion Detection System (IDS) is primarily designed to detect unauthorized access or anomalies within a network, and thus the CIA tenet it is most associated with is integrity. IDS systems work by monitoring network traffic and comparing against a database of known threats, looking for irregularities, which can indicate that the integrity of the system has been compromised. While they might also play a role in ensuring availability by mitigating the effects of an attack to keep systems up and running, their primary focus is to detect breaches that could lead to unauthorized alterations of data.
The CIA triad is a widely used model in information security that consists of three key principles: confidentiality, integrity, and availability. In the context of intrusion detection systems (IDS), the tenet most likely to be detected is integrity. IDS are designed to monitor network traffic and detect any unauthorized changes or modifications to data or systems. When an IDS detects any integrity violations, such as unauthorized alterations or tampering, it can alert the administrators to take appropriate action to mitigate the threat.
