In the context of OCI's Zero Trust Packet Routing, which principle emphasizes the necessity of explicitly defining and enforcing access controls at every stage of network communication?
Zero Trust Context: Assumes no inherent trust, requiring explicit controls at all network stages.
Evaluate Principles:
Implicit Trust: Assumes trust, opposite of Zero Trust; incorrect.
Least Privilege: Grants minimal access, explicitly enforced; aligns with Zero Trust.
Perimeter Security: Relies on boundary protection, not Zero Trust; incorrect.
Network Segmentation: Isolates networks, a tactic not a principle; incomplete.
Conclusion: Least Privilege is the core principle for explicit access control.
Zero Trust Packet Routing in OCI emphasizes Least Privilege. The Oracle Networking Professional study guide states, 'The Least Privilege principle in Zero Trust requires that access controls be explicitly defined and enforced at every network communication stage, ensuring no implicit trust' (OCI Networking Documentation, Section: Zero Trust Networking). This drives granular security policies.
