Endpoint security protects laptops, desktops, servers, mobile devices, and other systems that connect to an organization’s networks or services. It combines secure configuration, timely patching, encryption, access controls, application restrictions, and monitoring. Endpoint detection and response (EDR) tools record activity such as process execution, persistence, and configuration changes so analysts can investigate suspicious behavior.
Endpoints are common entry points for exploiting vulnerable software, stealing credentials, or installing unauthorized code. Effective programs maintain an accurate device and software inventory, prioritize vulnerabilities that are exposed or actively exploited, and apply least privilege to limit what a compromised device or account can do. They also need tested procedures to contain or isolate devices, investigate them without unnecessarily destroying evidence, and govern endpoint telemetry and administrator access to protect privacy and support applicable data-handling obligations.
