Why is a Magento Code Audit necessary?

Recently, Magento (Adobe Commerce) has grown to be one of the most popular and sought-after e-commerce platforms due to its distinctive features and user-friendly interface.  It holds a global market share of 2.56% and is currently in use by 149,024 live websites.

The platform runs on codes written using PHP. Each functionality that you see in the front-end is supported by relevant codes at the back-end to keep the website running. Also, it is loaded with numerous extensions that can be customized to suit your store’s unique needs—further, adding to its complexity. However, installing too many can be a recipe for disaster.

Sometimes, bugs can slip through the cracks, causing frustrating glitches that disrupt the user experience. You might not even be aware of these issues until it’s too late, and your website has already suffered some serious damage. 

It’s like driving a car with a flat tire and not realizing why it’s not running smoothly.

So, in a nutshell, we can say that your website’s functionality relies on its code and installed extensions, which act as building blocks for your e-commerce store. If they don’t function properly everything will fall out of place. Your entire website can suffer, becoming disorganized and chaotic.

Hence, this is where a Magento code audit becomes necessary. It identifies and addresses areas in your codebase that need attention, thereby preventing any significant damage.

If you observe any of the following indications, it is recommended that you promptly hire a professional Magento service provider :

●   Poor website speed causing sales drop

●   Unresponsive tabs or broken links

●   Interface errors

●   Frequent website crash

●   Displaying error messages

●   Unauthorized warning messages

●   Running on an outdated Magento version

What’s usually checked during a Magento Code Audit

Security Vulnerabilities

Security is one of the most critical aspects to check during a Magento Code Audit. Hackers are always in search of security vulnerabilities in your store to gain unauthorized access and steal sensitive customer data. Some of the major security vulnerabilities covered under code audit are:

●   SQL injection attacks

●   Cross-Site Scripting Attacks (XSS)

●   Server Misconfiguration/ Server Security

●   Remote Code Execution (RCE)

●   Code Vulnerabilities

●   Password Policies

●   Third-Party Extensions

●   Secure Communication

To overcome all these security concerns, always keep your Magento website up-to-date. Review and install security patches as and when released to prevent known vulnerabilities from being exploited by attackers. Implement HTTPS throughout your website with updated SSL certificates to secure communication between the browser and the server. Use SSH password-based authentication. Regularly perform code audits to identify vulnerabilities arising from code customization. Also, ensure that all the third-party extensions are vetted before installation.

Performance Optimization

Optimizing website performance is most critical in improving conversions. Because a website that loads slowly leads to poor user experience resulting in lost sales. The code audit performs an analysis of the codebase to check for areas that can be optimized for performance by

●   Reducing page load time

●   Implementing configured caching

●   Reducing unnecessary database calls

●   Avoiding typical code customization

●   Using minified CSS/JS versions

●   Checking for cross-browser compatibility

●   Image optimization

●   Database optimization

●   Removing irrelevant third-party extensions

New Relic, a SaaS-based platform performance monitoring tool, is now one of the most popular tools among Magento developers as it helps in making data-driven decisions based on real-time observability.

Magento Core Integrity Review

Your store has a Magento core with inbuilt modules which should be kept unmodified.

In the code audit, developers check for any changes in the Magento core to ensure that it is tamperproof to help with future website upgrades. However, in certain circumstances, novice programmers can mess with the core by directly overwriting additional functionalities to it. You must be aware that the Magento core once modified loses its integrity and may sometimes become irreparable causing severe security and performance issues.

So, any additional functionalities you wish to implement should be added as Magento extensions or third-party extensions.

Code Quality Review

Another important area to cover under code audit is code quality. It checks your Magento module code, theme code, and third-party codes.

If your store is running on poorly written codes, it is more likely to encounter downtime due to bugs, security vulnerabilities, and performance issues.

Our developers are here to figure out your code quality and ensure that your website has the highest quality code in place by checking the following:

●   Best coding practices as per Magento coding standards.

●   Consistent naming conventions

●   Modularized codes

●   Compatibility with custom codes and third-party extensions

●   Using reliable third-party applications and extensions

To identify further inconsistencies in your code PHP Code Sniffer can be used. Your auditor may also consider refactoring CSS if any inconsistencies and redundancies are observed while reviewing your theme code.

Database Integration

Auditing your database is also equally important to improve its speed, efficiency, and security. It allows in identifying any possible vulnerabilities that may set holes in your site for attackers.

So, our developers during the audit ensures to

●   Upgrade your site to the latest version of Magento

●   Normalize the database to enhance flexibility and security.

●   Control redundancy

●   Follow proper indexing.

●   Check security features and identify potential breaches on the updated versions

Magento offers a Site-Wide Analysis Tool (SWAT) to perform a thorough checkup of the store’s health. It conducts a performance analysis of your site and identifies issues to come up with the best possible solutions as per industry standards.
