S3 Bucket-Based Secure File Storage System
Objective:
To develop a secure and scalable file storage system using Amazon S3 buckets, enabling users to upload, manage, and retrieve files from the cloud with access control, encryption, and organized storage.
Why Choose This Project:
-
Provides a reliable and scalable storage solution leveraging AWS S3.
-
Ensures secure file storage with encryption and controlled access.
-
Allows easy integration with web or mobile applications for file management.
-
Demonstrates practical cloud storage management and security practices.
Key Features:
| Feature | Description |
|---|---|
| File Upload & Download | Users can upload and download files securely through the system. |
| AWS S3 Integration | Files are stored in S3 buckets with configurable access policies. |
| Access Control | Role-based permissions for upload, download, and deletion. |
| Encryption | Server-side encryption (SSE-S3 or SSE-KMS) for secure storage. |
| Versioning | Maintain multiple versions of files for rollback and recovery. |
| Logging & Monitoring | Track uploads, downloads, and access attempts using AWS CloudTrail. |
| Folder Organization | Categorize files into directories or project-based folders. |
| Notification System | Alerts for file uploads, deletions, or unauthorized access attempts. |
Technology Stack:
-
Frontend: HTML, CSS, JavaScript, React.js / Angular.
-
Backend: Node.js (Express) or Python (Flask / Django).
-
Database: MySQL / PostgreSQL / MongoDB for metadata (file names, users, timestamps).
-
Cloud Storage: AWS S3 for file storage.
-
Security & Encryption: AWS KMS for encryption, IAM policies for access control.
-
Monitoring & Notifications: AWS CloudTrail, SNS or email notifications.
