🔐 Cybersecurity Glossary

A network security technology that monitors network traffic and system activities for malicious behavior or policy violations, and can automatically take action to block or prevent detected threats. IDPS combines intrusion detection (IDS) capabilities that identify and alert on threats with intrusion prevention (IPS) capabilities that actively block attacks in real-time using signature-based detection, anomaly detection, and behavioral analysis.

A cybersecurity framework that eliminates implicit trust by requiring continuous verification of all users, devices, and network flows before granting access to resources. Zero Trust operates on the principle of 'never trust, always verify' and assumes breach as the default state, implementing least-privilege access controls, micro-segmentation, and continuous monitoring regardless of whether requests originate inside or outside the network perimeter.

A security framework that eliminates implicit trust and requires continuous verification of every user and device attempting to access network resources, regardless of their location inside or outside the network perimeter. ZTNA operates on the principle of 'never trust, always verify' and grants least-privilege access based on identity, context, and policy compliance.
