Insecure service configuration - ELB
Description
A misconfiguration or default setting on Elastic Load Balancers that can cause to unintentionally increase the attack surface of the company cloud infrastructure.
Impact
- Result in the connection between load balancer and server being exploited.
- The front-end connection between the client and the load balancer is vulnerable to eavesdropping and man-in-the-middle (MitM) attacks.
Recommendation
- Application load balancers should use acceptable policies.
- Create a custom ELB SSL security policy that contains secure ciphers.
- Strongly advised that the load balancer uses a secure listener.
Threat
Unauthorized attacker from adjacent network performing a MitM.
Expected Remediation Time
⌚ 60 minutes.
