Many organizations are considering moving their workloads from on-premise data centers to the cloud, especially to Amazon Web Services (AWS), which offers a wide range of services and features for scalability, reliability, and performance. However, moving to the cloud also involves security challenges and risks that need to be addressed carefully. In this blog post, we will discuss some of the security aspects of moving to AWS from on-premise and how to mitigate them.
Shared Responsibility Model
One of the key concepts to understand when moving to AWS is the shared responsibility model, which defines who is responsible for what in terms of security and compliance. According to AWS, "Compliance is a shared responsibility between AWS and the customer" and "Customers can feel confident in operating and building on top of the security controls AWS uses on its infrastructure". This means that AWS is responsible for securing its global infrastructure, including physical facilities, hardware, software, networking, and storage. On the other hand, customers are responsible for securing their data, applications, operating systems, network configurations, identity and access management (IAM), encryption keys, firewalls, patches, updates, backups etc.
Therefore, customers need to understand their role and obligations in ensuring security and compliance when moving to AWS. They also need to leverage the tools and best practices that AWS provides for securing their workloads in the cloud.
One of the main concerns when moving data from on-premise to AWS is data protection. Data protection involves ensuring data confidentiality (preventing unauthorized access), integrity (preventing unauthorized modification), availability (preventing unauthorized deletion or loss), privacy (complying with regulations and policies), and sovereignty (complying with jurisdictional laws). To achieve data protection in AWS³, customers can use various methods such as:
Another important aspect when moving workloads from on-premise to AWS is network security. Network security involves ensuring that the network traffic between on-premise and AWS, as well as within AWS, is secure and reliable. To achieve network security in AWS¹, customers can use various methods such as:
Moving to AWS from on-premise offers many benefits but also requires careful planning and execution for security aspects. Customers need to understand the shared responsibility model, data protection methods, network security methods, and other best practices that AWS provides for securing their workloads in the cloud.
