Which technology is used to detect potential intrusions?

Intrusion Detection is the technology specifically designed for monitoring network traffic or system activities for malicious actions or policy violations. It involves analyzing patterns and behaviors within the data to identify irregularities that may indicate an intrusion attempt. By deploying various detection mechanisms, such as signature-based or anomaly-based systems, organizations can recognize potential security breaches in real-time and respond accordingly to protect their infrastructure.

Data Encryption primarily serves the purpose of protecting the confidentiality of data by encoding it, making it unreadable to unauthorized users. While important for securing information, it does not inherently provide mechanisms for detecting intrusions.

Access Control focuses on limiting who can view or interact with resources within a system, ensuring that only authorized users gain access. This is critical for maintaining security but does not include functions for detecting intrusions.

Key Management pertains to the handling of cryptographic keys used in encryption and decryption processes. While it is essential for maintaining secure communication and data integrity, it does not have capabilities for monitoring or detecting unauthorized access attempts or intrusions.

Thus, the focus on detecting potential intrusions distinctly places Intrusion Detection as the correct and relevant technology for this purpose.
