name: Unrestricted OpenSearch Access
|
|
author: princechaddha
|
|
severity: critical
|
|
description: |
|
|
Checks EC2 security groups for inbound rules allowing unrestricted access to OpenSearch on TCP port 9200. Restricts access to essential IP addresses only.
|
|
impact: |
|
|
Unrestricted access to OpenSearch can lead to unauthorized data access, modification, or denial of service attacks.
|
|
remediation: |
|
|
Modify EC2 security group rules to limit access to TCP port 9200 for OpenSearch, allowing only necessary IPs, implementing the principle of least privilege.
