When hosting container-based websites in the cloud, here are ten security aspects to pay attention to:

1. Image security: Use trusted, verified container images and regularly scan them for vulnerabilities.

2. Access control: Implement strict access controls and authentication mechanisms for accessing containers and their resources.

3. Network segmentation: Isolate containers using network segmentation techniques to minimize the impact of potential breaches.

4. Secrets management: Securely manage sensitive information, such as passwords and API keys, using secret management solutions.

5. Runtime security: Monitor and protect containers during runtime by implementing intrusion detection and prevention systems.

6. Logging and monitoring: Enable comprehensive logging and monitoring to detect and respond to security incidents promptly.

7. Regular updates and patching: Keep container images, dependencies, and the underlying host system up to date with the latest security patches.

8. Least privilege principle: Apply the principle of least privilege, granting containers only the permissions they require to function.

9. Secure communication: Encrypt data in transit using secure protocols like HTTPS and implement secure communication between containers.

10. Compliance and governance: Ensure compliance with relevant security standards and regulations, and establish governance policies for container management.
