Network Policies and Least-Privilege Networking
Lock down container-to-container traffic with default-deny network policies, explicit allow rules, and the principle of least privilege applied to networking.
Default-Open Is Risky
By default, containers in a cluster can usually talk to every other container. A compromised pod can then reach databases and internal services freely. Network policies close that door.
Least Privilege for Networking
The principle of least privilege applies to traffic: a service should accept and make only the connections it truly needs - nothing more.
