If you’re developing themes and plugins for WordPress, you know how important appealing design and bug-free code are. But what about WordPress security? Keeping up to date with the latest security standards is not only important for your buyers, but also for you as the developer. Remember, you’re not just building themes and plugins – you’re building a reputation at the same time. Check out these simple WordPress security tips that could help you stand out from the crowd as an established, reliable developer.

Update WordPress Regularly

Every now and then WordPress releases a major update that introduces powerful new features, time-saving tweaks and other adjustments. However, the team behind WordPress isn’t working just on new features and visual changes – they’re also tirelessly working on patching any security holes in order to provide highest security standards possible. By focusing on WordPress security and making sure your theme or plugin is compatible with the latest version of WordPress, you’ll be adding value to your theme and building a reputation of a trust-worthy developer.

Use WordPress Functions And Libraries

Before you even begin thinking about writing the code for a great new feature, make sure you check if you can use native WordPress functions and libraries to do whatever you’re trying to do with your custom code. This way, your theme or plugin will be less prone to vulnerabilities, and if a bug is discovered, it will be fixed by WordPress. There are countless core scripts written by WordPress, so in order to ensure the highest WordPress security, always check before adding new libraries.

Use WordPress Nonces

Nonce stands for number used once, and it’s a special string generated by WordPress to identify the person submitting a form or adding a comment, and to protect against malicious hacking attacks. Nonces are great for WordPress security because they expire in 24 hours, ensuring that no one can copy them and reuse them in another HTTP request, for example.

User Input And Output Can Affect WordPress Security As Well

In order to ensure the highest WordPress security, you need to validate the data you get back from the user. There are various ways to do that: for input data, for example, you can use sanitize_text_field() to check for invalid characters, and strip all the tags, among other things. You can also use esc_html() and sanitize_email() to sanitize the information displayed to the user.
