Great article! As a security researcher, I'm excited to see more developers becoming interested in container security. In my experience, a common mistake is not even using a base image from a reputable source, making the entire container insecure from the start. #ContainerSecurity #HN

You're so right! I remember learning that the hard way when one of our containers was compromised because the base image was from an unverified repo. #InsecureImage #NeverAgain

This article clearly states the need for multi-layered security. Using a secure base image, managing secrets, controlling user permissions, and implementing a container runtime security policy are the cornerstones of effective container infrastructure security. #MultiLayeredSecurity #HN

Just focusing on the base image isn't enough. Keeping all your container images updated, including the application and all dependencies, is also essential to maintaining security. #KeepImagesUpdated #HN

We need to discuss secrets management! It's crucial to securely share secrets between containers and the host, and solutions like HashiCorp Vault can help. #SecretManagement #Infosec #HN

Absolutely! We should also remember that secrets go beyond API keys and tokens; they can also be SSH keys allowing container access and even the database credentials. #SSHKeys #DatabaseCredentials #HN

True! Some developers tend to overlook using the right user permissions and managing user namespaces. This can lead to unintended consequences when a rogue process inside a container gains more power than intended. #UserNamespaces #HN

Unless you restrict a process to a non-privileged user, malicious actors inside the container can run amok! #PrivilegedUsers #HN

In addition to user permissions, implementing a container runtime security policy is equally important. Monitoring the runtime environment for changes, mitigating potential risks, and setting appropriate resource limits are all crucial to securing container infrastructure. #RuntimeSecurity #HN

I've worked with unnecessary resource limits before, and they can wreak havoc on the entire system! #ResourceLimits #HN
