Docker-based applications offer several security benefits:
Easier to Patch: Docker containers include only the dependencies required by the application, making it easier to identify and patch vulnerabilities. This minimizes the attack surface and simplifies the management of security updates.
Separation of Applications: Docker containers enable the separation of applications that traditionally run on the same host. This isolation improves security by reducing the risk of one compromised application affecting others on the same host.
