Overview In AWS, an Elastic Load Balancer (ELB) is a foundational component for building resilient and scalable applications. Its primary function is to distribute incoming traffic across multiple backend compute resources, typically Amazon EC2 instances. However, a common and critical misconfiguration occurs when an ELB is connected to only a single healthy EC2 instance. This […]

Overview In any AWS environment, the Elastic Load Balancer (ELB) acts as the front door for your applications. It manages incoming traffic, distributing requests across your compute resources to ensure availability and performance. However, because it sits at the network edge, its configuration is a critical control point for your entire security posture. An improperly […]

Overview In the AWS ecosystem, the security of data in transit is a foundational requirement. AWS Elastic Load Balancing (ELB) acts as the primary gateway for application traffic, making its configuration a critical control point for your security posture. A common but dangerous misconfiguration is the use of outdated and insecure cryptographic protocols, specifically SSLv2 […]

Overview In any AWS environment, the Elastic Load Balancer (ELB) acts as the front door for application traffic, managing user connections and securing data in transit. A critical part of its job is negotiating the encryption protocols and ciphers used for every HTTPS session. However, when these load balancers are configured with outdated security policies, […]

Overview In any sophisticated AWS environment, Elastic Load Balancing (ELB) is the front door for application traffic. Its configuration directly impacts your application’s ability to withstand failures and manage user requests efficiently. A critical, yet often overlooked, setting is cross-zone load balancing. This feature determines whether traffic is distributed evenly across all registered instances in […]
