You must gain visibility into your running environment so you can detect and respond to threats as they arise.\n\nIf you proactively secure your containers and Kubernetes deployments at the build and deploy phases, you can greatly reduce the likelihood of security incidents at runtime and the subsequent effort needed to respond to them.\n\nFirst, monitor the most security-relevant container activities, including\n\nProcess activity Network communications among containerized services Network communications between containerized services and external clients and servers\n\nDetecting anomalies by observing container behavior is generally easier in containers than in virtual machines because of the declarative nature of containers and Kubernetes. These attributes allow easier introspection into what you have deployed and its expected activity.\n\nAttribution: Adapted from OWASP Cheat Sheet Series under CC-BY-SA-4.0.
