What does intrusion detection primarily aim to prevent?

Intrusion detection primarily aims to prevent unauthorized access to secured areas by monitoring and analyzing activities within a given environment or system. It involves the use of various technology-based solutions, such as alarms, surveillance systems, and software applications, that can detect and alert security personnel to potential breaches or suspicious behavior in real-time. This proactive approach is essential in protecting sensitive information and facilities from threats, whether they are physical breaches in a physical security context or cyber threats in a digital landscape. By focusing on preventing unauthorized access, intrusion detection plays a crucial role in maintaining the integrity and security of an organization’s assets and resources.
