Which step would give an attacker a foothold in a cluster butno long-term persistence?
Correct Answer: C
* Starting a process in a running containerprovides an attacker withtemporary execution (foothold) inside the cluster, but once the container is stopped or restarted, that malicious process is lost. This means the attacker has nolong-term persistence. * Incorrect options: * (A) Modifying objects inetcdgrants persistent access since cluster state is stored in etcd. * (B) Modifying files on thehost filesystemcan create persistence across reboots or container restarts. * (D) Creating a restarting container directly on the host via Docker bypasses Kubernetes but persists across pod restarts if Docker restarts it. References: CNCF Security Whitepaper - Threat Modeling section: Describes howephemeral processes inside containersprovide attackers short-term control but not durable persistence. Kubernetes Documentation - Cluster Threat Model emphasizes ephemeral vs. persistent attacker footholds.
