Implementing Secure Networking with OCI Network Security Groups (NSGs) Using CLI

Posted on by Osama Mustafa in Uncategorized

Introduction

  • Overview of OCI NSGs for network security policies.

Step-by-Step Guide

  1. Creating NSGs
oci network nsg create --compartment-id <compartment_OCID> --display-name "MyNSG" --wai

Defining Ingress and Egress Rules

Adding Ingress Rule:

oci network nsg rules add --nsg-id <NSG_OCID> --direction INGRESS --protocol tcp --source <CIDR_block> --source-type CIDR_BLOCK --destination-port-range 22

Adding Egress Rule:

oci network nsg rules add --nsg-id <NSG_OCID> --direction EGRESS --protocol tcp --destination <CIDR_block> --destination-type CIDR_BLOCK --destination-port-range 80

Applying NSGs to Resources

Applying NSG to VCN:

oci network vcn update --vcn-id <VCN_OCID> --nsg-ids <NSG_OCID>

Securing a web application deployment on OCI by configuring NSGs to allow specific inbound and outbound traffic flows between instances and the internet, enhancing network security posture.

Thank you
