Ensure ECS task definitions use read-only root filesystem
Container root filesystems should be read-only to prevent malicious write operations.
Security Impact
Writable root filesystems allow attackers to modify binaries, install malware, or persist changes.
How to Remediate
Set 'readonlyRootFilesystem' to true in container definitions. Mount writable volumes where needed.
