Overview In any AWS environment, security groups act as the fundamental virtual firewalls controlling network traffic to your resources. One of the most critical and common misconfigurations is assigning an unrestricted security group to an Amazon Relational Database Service (RDS) instance. This configuration flaw essentially opens your database to the entire internet, creating a significant […]

Overview In the AWS shared responsibility model, while AWS secures the underlying cloud infrastructure, you are responsible for securing the data you run within it. A critical aspect of this responsibility is protecting data in transit—the information flowing between your applications and your databases. For services like Amazon Relational Database Service (RDS), this means ensuring […]

Overview Amazon Aurora Serverless offers incredible flexibility and scalability, allowing database capacity to align automatically with application demand. However, this dynamic environment can create significant operational blind spots if not managed correctly. The ephemeral nature of serverless compute instances means that critical database logs—the digital evidence of every query, error, and access attempt—can be lost […]

Overview In the AWS ecosystem, maintaining the cryptographic integrity of data in transit is a foundational security principle. A key component of this is the lifecycle management of SSL/TLS certificates for services like Amazon Relational Database Service (RDS) and Aurora. Certificate rotation is the process of replacing an old or expiring certificate with a new […]

Overview In AWS, managing data is a core responsibility, and the configuration of automated backups for the Amazon Relational Database Service (RDS) is a critical control point. A common oversight is setting an insufficient backup retention period—the duration for which automated backups are preserved. This seemingly minor setting has major implications for an organization’s ability […]
