Challenge:
The current system relies on unsupported and end-of-life technologies, which introduces significant risk and operational limitations:
PHP 7.2 is end-of-life, meaning it no longer receives security updates or bug fixes, exposing the application to known and future vulnerabilities.
MySQL 5.7 is no longer supported, increasing the risk of data integrity issues, performance degradation, and security exploits.
Known vulnerabilities remain unpatched, leaving the system susceptible to cyberattacks, compliance violations, and potential service disruptions.
These issues collectively increase security risk, maintenance costs, and technical debt, while limiting the ability to scale or integrate modern features.
Solution:
Modernize the technology stack by upgrading to supported, secure, and actively maintained versions:
Upgrade PHP to a currently supported LTS version (e.g., PHP 8.1 or 8.2) to ensure ongoing security patches and performance improvements.
Migrate MySQL 5.7 to MySQL 8.0 (or an alternative supported database such as PostgreSQL) to gain enhanced security, improved query performance, and long-term support.
Implement a vulnerability management and patching strategy to ensure all dependencies and system components remain up to date.
This modernization will reduce security risks, improve system performance, and ensure long-term maintainability.
Impact:
After implementation, the organization will achieve:
Significantly reduced security risk through supported software and active patching.
Improved system stability and performance, with faster execution and optimized database operations.
Regained compliance readiness, supporting audits and regulatory requirements.
Lower long-term maintenance costs due to reduced technical debt and easier upgrades.
Future-ready architecture, enabling scalability, new features, and integrations.
