Runtime Application Self-Protection (RASP)

Runtime Application Self-Protection is a security technology that enables applications to detect and respond to attacks in real-time during execution.

RASP solutions are embedded within or attached to an application's runtime environment, allowing them to monitor application behavior, analyze traffic, and identify malicious activity from within the application itself.

Unlike traditional security tools that operate at the network perimeter or host level, RASP provides inside-out protection by having direct visibility into application logic, data flow, and execution context. This positioning allows RASP to detect sophisticated attacks that might bypass external security controls, including SQL injection, cross-site scripting, and other application-layer exploits.

When RASP detects malicious activity, it can take immediate protective action such as blocking suspicious requests, terminating malicious sessions, or alerting security teams. The technology operates with minimal latency since it's integrated directly into the application runtime, making it particularly effective for protecting web applications and APIs in production environments.

RASP solutions complement other security measures by providing an additional layer of defense that doesn't rely on signatures or predefined attack patterns, instead analyzing actual application behavior to identify anomalies and threats in real-time.
