Why are containers uniquely suitable for runtime security based on allow lists?

Containers are typically designed to run a specific application or service, meaning they have a limited and well-defined set of processes. This makes it easier to implement and manage runtime security based on allow lists, as any deviation from the expected processes can be quickly identified and mitigated.
