Overview
The app’s purpose is to streamline employee reporting and facilitate efficient communication between employees and employers. It provides a user-friendly platform for employees to submit reports and allows employers to manage and respond to those reports effectively. The app aims to improve transparency, accountability, and workplace safety within organizations.
Challenges
In my participation in the project, my focus was on solving problems from three different perspectives: troubleshooting, usability, and security. Unlike typical applications, the primary goal was not conversion or sales, but rather enhancing the usability of the website and ensuring its security. Given the sensitive nature of the data involved, any potential leaks could have significant consequences for the company. Therefore, my efforts were directed towards implementing robust security measures and improving the overall user experience to mitigate these risks and ensure a safe and user-friendly environment for the application.
Employer’s perspective
- Confusing navigation: Employers struggle to navigate the app due to unclear menus and navigation elements.
- Inefficient task management: Employers find it difficult to track and manage the status of employee reports effectively.
- Lack of visual hierarchy: Important elements blend in with less relevant information, making it hard for employers to prioritize tasks.
- Inconsistent design patterns: Design inconsistencies create confusion and cognitive overload.
- Inadequate feedback and confirmation: Employers lack clear feedback on their actions within the app.

Security
Challenges with WordPress in the app:
- Lack of Native Encryption: WordPress lacks built-in encryption mechanisms for sensitive data, exposing it to potential breaches.
- Shared General Database: The default setup uses a single database for all users, increasing the risk of compromising multiple sites simultaneously.
- Vulnerabilities in Third-Party Plugins and Themes: Relying on external plugins and themes can introduce security vulnerabilities if not regularly updated.
- File Upload Risks: WordPress allows file uploads without strict security measures, enabling the potential execution of malicious scripts or dissemination of infected files.
- Brute-Force Attacks: WordPress is a frequent target for brute-force attacks due to weak login credentials and limited protection against multiple login attempts.
- Inadequate User Role Management: Insufficient control over user roles and permissions can lead to unauthorized access and data leakage.
- Absence of Two-Factor Authentication: WordPress lacks native support for two-factor authentication, increasing the risk of compromised accounts.
- Dependency on Shared Hosting: Shared hosting environments can compromise overall security, as vulnerabilities in one site can impact others on the same server.

- Regularly update the database management system to the latest version.
Implementing Encryption for Database Storage:
- Encrypt sensitive data stored in the database using strong encryption algorithms.
- Utilize encryption libraries or plugins to handle encryption and decryption processes.
- Keep encryption keys secure and separate from the database.
- Regularly review and update encryption mechanisms to ensure data remains protected.
Regular Database Backups
- Set up automated backup processes to regularly backup the WordPress database.
- Store backups in a secure location, separate from the live database.
- Perform periodic test restores to ensure the integrity and validity of backups.
- Implement a backup retention policy to manage and delete outdated backups.
Encryptions key management
To implement proper key management practices for securely storing and managing encryption keys, follow these steps:
- Generate strong keys using a reliable algorithm.
- Encrypt the encryption keys using a separate master key or passphrase.
- Store the encrypted keys in a secure location such as a hardware security module (HSM) or a secure key management system.
- Limit access to the keys to authorized personnel using role-based access control (RBAC).
- Regularly rotate the encryption keys to mitigate long-term exposure.
- Monitor key usage and detect any suspicious activities.
- Implement a backup strategy for the keys and periodically test the recovery process.
- Conduct audits to ensure compliance with security standards and regulations.

Summary
In summary, this case study focused on enhancing the security and user experience of a WordPress-based web application. The project addressed various security risks by prioritizing security measures such as keeping the WordPress core up-to-date, securing the wp-config.php file, implementing strong password policies, and using a web application firewall (WAF). Database security was improved through encryption, regular backups, and monitoring. File upload security and continuous monitoring were also implemented.
From a user experience perspective, the employer’s dashboard was enhanced with features such as easy generation of PDF reports, secure archiving of applications, and a bug reporting system. The design of the dashboard emphasized visual clarity, clear hierarchy, and efficient navigation. The employee’s form was improved with a multi-step layout, validation, and progress indicators to streamline the submission process.
Challenges specific to WordPress, such as its vulnerabilities and the need for careful configuration, were addressed by removing redundant plugins, securing the database, and implementing proper encryption practices. The use of WordPress presented certain limitations, but through careful planning and implementation, the project successfully achieved the desired level of security and user experience.
The approach to solving UX problems involved conducting research through customer surveys, feedback from bug reports, and manual testing. Functional and visual enhancements were implemented based on user feedback, resulting in improved usability, better visual hierarchy, and a more organized interface.
Overall, this project required a comprehensive understanding of WordPress security, user experience best practices, and the specific needs of the web application. The collaboration between the designer and developer was instrumental in identifying and addressing the challenges associated with WordPress, ultimately resulting in a secure and user-friendly web application.
