Runtime Security

Definitions

1. The monitoring and protection of applications, containers, hosts, or serverless workloads during execution. Runtime security focuses on what is actually happening live, such as process behavior, system calls, network connections, and policy violations, rather than only on predeployment risk.

   In plain English: Security focused on protecting software and workloads while they are actively running.

   Example: "The container image looked clean in the registry, but runtime security later caught it spawning a shell and reaching an unexpected external host."
