Implementing IP Whitelisting in Oracle Cloud Infrastructure (OCI)
Implementing IP Whitelisting in Oracle Cloud Infrastructure (OCI)
IP whitelisting in Oracle Cloud Infrastructure (OCI) helps secure your tenancy by restricting access only to trusted IP addresses. Here’s a step-by-step guide to configure it using Security Lists or Network Security Groups (NSGs) within your Virtual Cloud Network (VCN).
Step-by-Step Guide:
- Login to OCI Console: Go to cloud.oracle.com and sign in with your tenancy credentials.
- Navigate to Networking: From the main menu, choose Networking → Virtual Cloud Networks (VCN) and open your VCN.
- Access Security List or NSG: Identify the subnet or compute instance you want to protect and open its Security List or Network Security Group.
- Add an Ingress Rule:
- Source Type:
CIDR - Source CIDR: your trusted IP range (e.g.,
203.0.113.0/24) - Protocol:
TCP - Port Range:
22for SSH or443for HTTPS
- Source Type:
- Save and Test: Click Add Rule. Test access from a whitelisted IP and ensure others are blocked.
- Monitor and Audit: Use OCI Audit logs to track rule changes and confirm policy compliance.
Following these steps ensures your Oracle Cloud environment is protected from unauthorized network access while maintaining the flexibility of OCI networking.
