Abstract

Protecting sensitive information is one of the great challenges that an organization and individuals face in this era of cloud computing. This project focuses on designing and implementing a secure, scalable, and cost-effective file storage system using AWS S3 along with its integrated services: KMS, IAM, and VPC. The advanced encryption, network isolation, and strict access controls make the system assure confidentiality, integrity, and accessibility of data. Important characteristics involve server-side encryption by the help of AWS KMS, versioning in place, and the least privileged approach adopted in IAM policies. Both functional and security tests result in 98% of file operations with average 200 ms of response times and 100% of data integrity. Leveraging the cloud infrastructure of AWS, as well as automating key processes, the project demonstrated the possibility of using a mix of cloud-native tools with custom development to address significant data security challenges. It thus provides a blueprint for organizations looking to store sensitive information securely in a cloud environment.
