Description​

Audit and modify AWS EC2 Security Group rules to restrict access to MongoDB instances by blocking unrestricted inbound traffic to ports 27017 - 27020. The access should be limited to specific IP addresses or internal networks to reduce the risk of unauthorized access and potential data breaches.

Rational​

MongoDB is a NoSQL database, and exposing it to the open internet (e.g., via 0.0.0.0/0) poses a significant security risk. Unrestricted access can lead to data exfiltration, unauthorized changes, and other malicious activities. Restricting access to MongoDB to trusted IP ranges or systems ensures that only authorized users or applications can interact with the database, mitigating the risk of security breaches and reduces the attack surface.

Impact​

Requires careful implementation to ensure legitimate users and systems maintain access.

Audit​

This policy marks an EC2 Security Group as INCOMPLIANT if it contains a rule that meets all the following conditions:

  • The Direction is set to Inbound.

Remediation​

From Command Line​

  1. Run the following command to remove or modify the unrestricted rule for MongoDB access:
aws ec2 revoke-security-group-ingress \
--region {{region-name}} \
--group-id {{security-group-id}} \
--protocol {{protocol}} \
--port {{27017}} \
--cidr {{0.0.0.0/0 or ::/0}}

  • Optionally, run the authorise-security-group-ingress command to create a new rule, specifying a trusted CIDR range instead of 0.0.0.0/0.

  1. Confirm the changes by describing the security group again and ensuring the unrestricted access rule has been removed or appropriately restricted:
aws ec2 describe-security-groups \
--region {{region-name}} \
--group-ids {{security-group-id}} \
--query 'SecurityGroups[*].IpPermissions[?FromPort==`27017`].{CIDR:IpRanges[*].CidrIp,Port:FromPort}'
  1. Monitor MongoDB access to ensure it's unaffected by the changes.

💼 APRA CPG 234 → 💼 45 An understanding of plausible worst case scenarios can help regulated entities identify and implement additional controls to prevent or reduce the impact of such scenarios. One example is malware that infects computers and encrypts data, both on the infected computer and any connected storage, including (corporate) networks and cloud storage. Such attacks reinforce the importance of protecting the backup environment in the event that the production environment is compromised. Common techniques to achieve this include network segmentation, highly restricted and segregated access controls and network traffic flow restrictions.3537no data
