What is the goal of "intrusion detection"?

The goal of "intrusion detection" primarily revolves around identifying unauthorized access attempts to a system or physical premises. This process involves monitoring, analyzing, and responding to various activities that may indicate a breach or an attempted breach of security. By detecting these unauthorized attempts, organizations can take timely actions to prevent potential security incidents and protect their assets, both physical and digital.

While enhancing user experience, managing user credentials, and providing real-time video surveillance are important in a broader security context, they do not directly define the purpose of intrusion detection. The focus of intrusion detection is specifically to monitor for signs of intrusions, making option B the most relevant choice in this context.
