Task

Objective: The objective of this task is to design, implement, and analyze a secure file storage system. The system should ensure the confidentiality, integrity, and availability of stored files. Additionally, students are required to explore and implement encryption techniques, access controls, and other security measures to protect sensitive data

1. System Design: Define the requirements and functionalities of the secure file storage system. Design the architecture, specifying components such as servers, databases, and client interfaces. Clearly outline the security objectives (confidentiality, integrity, availability). Encryption Implementation:

2. Algorithms: Choose a suitable encryption algorithm(s) for securing stored files. Implement encryption and decryption mechanisms to protect the confidentiality of files. Discuss the key management strategy to securely handle encryption keys.

3. Access Control and Authentication: Implement access controls to restrict file access based on user roles and permissions. Integrate a robust authentication mechanism to verify the identity of users. Consider multi-factor authentication for enhanced security.

4. Audit Trail and Logging: Implement logging mechanisms to record user activities and file access. Create an audit trail for monitoring and analysis of security incidents. Discuss how the audit trail can be used for forensic purposes.

5.Data Integrity and Redundancy: Implement mechanisms to ensure the integrity of stored files. Explore techniques for redundancy and data backup to ensure availability. Discuss the recovery plan in case of data loss or system failure.

6. User Interface and User Experience: Develop a user-friendly interface for uploading, downloading, and managing files securely. Ensure that the user interface promotes security best practices and guides users on secure behavior.

7.Security Analysis: Conduct a thorough security analysis of the implemented system. Perform penetration testing to identify vulnerabilities and propose mitigation strategies. Provide a detailed report on the overall security posture of the system.

8. Documentation and Presentation: Document the entire design and implementation process. Prepare a presentation highlighting key features, security measures, and the rationale behind design choices.

Evaluation Criteria:

Functionality (30%): Successful implementation of encryption, access controls, and authentication. File upload/download functionality. Proper error handling and user feedback.

Security Measures (30%): Effectiveness of encryption techniques. Robustness of access controls and authentication. Quality of logging and audit trail.

User Interface (15%): User-friendly design. Clarity in guiding users on secure practices.

Security Analysis (15%): Thoroughness of security analysis. Effectiveness of mitigation strategies.

Documentation and Presentation (10%): Clarity and completeness of documentation. Quality of the presentation and ability to articulate key points.
