In the fast-evolving landscape of cloud computing, achieving operational excellence is crucial for organizations leveraging cloud services. Amazon Web Services (AWS) stands at the forefront of cloud providers, offering a comprehensive suite of services. One key aspect of AWS cloud operations competency is ensuring robust security measures to protect sensitive data and infrastructure. In this blog post, we’ll explore the significance of a security-centric approach in AWS cloud operations, with a particular focus on using AWS Security Hub to stay on top of security issues.

The Importance of Security in AWS Cloud Operations:

As organizations migrate their workloads to the cloud, the need for a robust security strategy becomes paramount. Security in AWS goes beyond traditional measures, encompassing identity and access management, data encryption, network security, and continuous monitoring. The shared responsibility model dictates that while AWS manages the security of the cloud infrastructure, customers are responsible for securing their data, applications, and configurations.
