ShareSafe’s mission is to provide online file-sharing-as-a-service and, as its developer, your mission is to build that service with robust security that will keep ShareSafe’s customers coming back. Using Java Spring Boot, you’ll build a simple file transfer REST API service that supports uploading and downloading of files, and you’ll identify and tackle file-upload vulnerabilities. You’ll add security by implementing a user-authentication layer using JSON Web Tokens (JWTs) and leveraging macaroons (cryptographic cookies) for secure file sharing.

To boost security, you’ll add file integrity checks and logging of all user and file activities. Then, you’ll take your REST API service’s security up a level by configuring AWS S3 to enable malware analysis, and implementing VirusTotal, a service that provides dynamic and behavioral analysis of shared files. When you’re done with these liveProjects, you’ll have built a file-sharing REST API with high availability, durability, and security, and ShareSafe’s customers will enjoy a secure file-sharing experience.

These projects are designed for learning purposes and are not complete, production-ready applications or solutions.

here's what's included

Project 1 Harden File Transferring

You’re a developer for ShareSafe, a company whose customers can upload personal documents, photos, and videos onto ShareSafe’s website using APIs. Your task is to enable ShareSafe’s users to share their files with others. Using Java Spring Boot, you’ll build a simple file transfer REST API service that supports uploading and downloading of files, and you’ll identify and tackle the file upload vulnerabilities of your REST API service. For backend file storage, you’ll implement Amazon Simple Storage Service (AWS S3). Finally, you’ll harden your service against the most common vulnerabilities by configuring and implementing AWS S3 encryption and access-management features. When you’re finished, you’ll have built a file transfer service that provides high scalability, durability, encryption, and backups, and allows your users to share their files with ease.

Project 2 Shareable File URLs

Help ShareSafe’s customers share with confidence. You’re a developer for a company that provides online file-sharing-as-a service. Its users can upload and share personal documents, photos, and videos onto ShareSafe’s website using APIs. Your task is to add security to ShareSafe’s file-transfer REST API service. You’ll implement a user-authentication layer using JSON Web Tokens (JWTs), provide authorization for shareable URLs by establishing the relationship between users and files, and leverage macaroons (cryptographic cookies) to provide a secure way for users to share files.

Project 3 File Integrity Monitoring

Give ShareSafe’s online file-sharing service a security boost. You’re a developer for a company whose customers can upload and share personal documents, photos, and videos onto its website using APIs. Your task is to enhance the security of ShareSafe’s file transfer REST API service by adding file integrity checks. Using JSON Web Tokens (JWTs), you’ll implement basic key generation, signing, and validation of data. You’ll refactor the API with the ability to validate digital signatures, and you’ll make identifying suspicious requests easier (and satisfy compliance requirements) by adding logging of all user and file activities.

Project 4 Malware Analysis

Build a better defense! As a developer at ShareSafe, a company that provides online file-sharing-as-a-service, your task is to uplevel the security of its REST API file-transfer service by adding functionality for checking uploaded files for malware. You’ll set up a robust infrastructure for malware analysis of files stored in AWS S3 buckets, integrate the infrastructure with the REST API service, and implement VirusTotal, a threat intelligence service that provides dynamic and behavioral analysis to shared files. When you’re finished, you’ll have built a solid line of defense against known malware and provided users with a secure file-sharing experience.
