Question

You have been tasked to build a system for managing online DVD rentals. Describe four plausible risks and indicate how you would retire them. Be as concrete as possible in describing the risks.

Short answer

Potential risks include data breaches, system downtime, legal compliance issues, and poor user experience. Mitigation involves encryption, redundant systems, legal consultation, and user-centric design.

Step-by-step solution

Identifying Risk 1 - Data Breach

A significant risk in managing online DVD rentals is the potential for a data breach, where sensitive customer information, including credit card details and personal data, could be exposed to unauthorized individuals. This can lead to financial loss and reputational damage.

Mitigation Strategy for Risk 1 - Data Encryption

To mitigate the risk of a data breach, implement strong data encryption methods for storing and transmitting data. Use secure protocols such as HTTPS and regularly update encryption algorithms to the latest standards to protect against exploits.

Identifying Risk 2 - System Downtime

System downtime can occur due to server overloads or technical failures, disrupting the film rental service and resulting in lost revenue and customer dissatisfaction.

Mitigation Strategy for Risk 2 - Redundant Systems

Deploy redundant systems and a robust failover mechanism to ensure continuity of service. This includes leveraging cloud services with auto-scaling capabilities and maintaining backup servers.

Identifying Risk 3 - Legal Compliance

There is a risk of failing to comply with various legal regulations, including copyright laws and consumer protection legislation, which can lead to fines and legal action.

Mitigation Strategy for Risk 3 - Legal Consultation and Monitoring

Employ legal experts to review the DVD rental process and ensure compliance with applicable laws. Implement routine audits to adapt to changing legal frameworks and update policies as needed.

Identifying Risk 4 - Poor User Experience

Users may face a poor experience due to a complicated interface or slow processing times, resulting in decreased user retention and negative reviews.

Mitigation Strategy for Risk 4 - User-Centric Design

Adopt user-centric design principles by conducting user research and usability testing. Regularly update the interface and optimize the system for performance based on user feedback.

Key concepts

Data Security

In online DVD rental systems, data security is crucial because customers trust the platform with their sensitive information. A major risk is a data breach, where unauthorized hackers may access and steal customer data, like credit card numbers and addresses. This not only harms customers but can also damage the business's reputation significantly.
To reduce the risk of data breaches, developers should implement strong data encryption methods. This ensures that even if data is intercepted, it remains unreadable to unauthorized users. For instance:

• Utilize HTTPS protocols for secure data transmission.
• Regularly update encryption algorithms to stay ahead of potential exploits.
• Employ two-factor authentication (2FA) to add an extra layer of security.
• Train staff on data security best practices to prevent human errors.

By following these measures, the risk of data breaches can be substantially reduced, ensuring both company integrity and customer trust.

System Reliability

System reliability ensures that the online DVD rental service operates smoothly without interruptions. Downtime can occur due to server overloads, hardware failures, or software bugs. When systems go down, customers can't rent DVDs, which can lead to revenue loss and customer dissatisfaction.
To enhance system reliability, businesses should invest in robust, redundant systems. Key strategies include:

• Implementing failover mechanisms that automatically switch to backup systems if the primary ones fail.
• Utilizing cloud services with auto-scaling to handle varying loads effectively.
• Regularly conducting system tests to identify and fix potential vulnerabilities.
• Maintaining updated documentation for troubleshooting and maintenance.

These strategies ensure that the rental service remains available at all times, keeping customers happy and preventing business disruptions.

Legal Compliance

Legal compliance is essential in managing an online DVD rental service because the business operates within multiple legal frameworks. These include copyright laws, consumer protection legislation, and data protection regulations. Failure to comply can result in hefty fines and legal consequences.
To ensure legal compliance, companies should engage with legal experts who can guide them through the requirements specific to their operations. Actions to take include:

• Conducting regular legal audits to ensure all processes meet current laws.
• Updating terms and conditions as necessary to reflect compliance with new regulations.
• Implementing licensing agreements for DVDs to ensure all content is legally rented.
• Monitoring changes in legislation to update business practices accordingly.

By prioritizing legal compliance, a company not only avoids legal trouble but also builds trust with customers, showing commitment to ethical practices.

User Experience Design

In software engineering, user experience (UX) design determines how users interact with an application. A poorly designed interface or slow performance can lead to frustration, causing users to leave and leave negative feedback.
To improve UX in an online DVD rental service, a user-centered design approach is recommended. Principles to follow include:

• Conducting user research to understand how customers navigate the system.
• Performing usability testing to identify pain points in the user journey.
• Updating the interface regularly based on usability test outcomes and feedback.
• Optimizing system performance to ensure quick load times and smooth operation.

Focusing on UX design helps create a seamless, enjoyable experience for users, boosting retention and positive reviews.
