Ensure OCI Console Access Is Restricted to Trusted Networks

MediumLevel 1Manual revieworacle-saas

Description

Ensure that access to the Oracle Cloud Infrastructure (OCI) Console is restricted to trusted networks (secure VPNs or private network endpoints) by configuring IAM Network Sources The OCI Console provides administrative access. If user credentials are compromised, unrestricted access from any IP address increases the attack surface. Reported as a manual review item: these Fusion/EPM/OCI IAM settings are reviewed in the Oracle SaaS and OCI consoles or reports.

How it is checked

Audit method: Manual review

This recommendation cannot be checked automatically. A scan lists it with these instructions when you pass --include-manual.

1. Navigate to Identity & Security, Domains, Security, Sign-On Policies. Confirm that console login rules reference a defined network source (for example, request.networkSource.name = <TrustedSource>). Verify that there is no policy rule permitting console access from any network. 2. Navigate to Identity & Security, Network Sources. Confirm that the trusted network source contains only approved IP addresses, CIDR blocks, or VCN subnets.

How it is fixed

Fix method: Guidance or infrastructure patch

1. Define a Network Source with trusted IP ranges or VCN subnets: Navigate to Identity & Security, Network Sources, Create Network Source. Add approved IPs or CIDRs. 2. Update the Sign-On Policy for the identity domain: Add a rule that allows console login only if request.networkSource.name matches the trusted network source. Add a default deny rule for all other networks. 3. Test access from both inside and outside the trusted network. 4. Maintain a secure break-glass account exempt from the restriction.
