Secure PHP Applications- What, Why, and How of invulnerable development?

Security is the key concern of every digital application. In today’s advanced technological world, your web applications are prone to several security attacks. We see this happening in our routine that many scripts written carelessly easily fall prey to unsecure digital environments.

Before you can think of securing your PHP powered application, you need to understand the concept of a security issue, that can be more complex and harmful than it may seem. Let’s start with a brief description of website security below:-

Every website built is often challenged by many threats sprouted by hijackers or illegitimate users where it is prone to data theft or authority lost or other kinds of financial risks to customers or retailer or even both ends.

Simply think about someone breaking your door and entering your home without your permission. Just like a thief who can take away your precious belongings, a hijacker is also pestilent for your website.

Many security breaches blare out from digital trade nearly every day. To name a few, most common security breaches- viruses and malware, increased security gaps, or DDOS (Denial of Service) attacks, data theft.

Why is it crucial to secure your PHP web application?

Hiring expert PHP developer for developing a web application is not only limited to a digital architecture with a functional backend and consistent front-end. It holds an underlying role of taking different measures to make sure that customers are safe while purchasing or dealing with you.

With every passing year, the rate of security thefts has been increasing and consumers are taking more precautious steps while making an online purchase. Moreover, a secured PHP application will help you with the following:-

- Protect against hackers,
- Increased reliability towards end users,
- Enhanced search engine ranks,
- Increased page load times,
- A cost-effective approach to make you a future proof.

Now, How can you make your PHP powered website secure during development and operational phases?

• Resisting SQL Injections and XSS Attacks

XSS attacks or cross-site scripting is a way of inserting malicious script on your web pages. Such vulnerability alone is capable enough to desolate your application’s reputation amongst end users.

Depending on the severity of a cross-site scripting attack, private data, user accounts, card details, etc. come at stake. You can experience webworm spread, session hijacking, etc.

To fight back XSS attacks, you can utilize safe HTML attribute, JavaScript variable, validated input, data sanitization, etc.

Similarly, SQL injections take place via URL parameters to manipulate your database or utilize a web form field. This insertion of rogue code in your application can fetch sensitive information as well as delete or modify the data.

One of the best ways to prevent SQL injections is to use parameterized queries that are easily accessible in most scripting languages.

• Limiting to index.php and Asset files

Index.php file is used to indicate a directory for web server in modern PHP. And, it acts as a single point entry for the whole application.

A limited web root to an index.php and Asset files is beneficial for saving your whole website from exposure to multiple security problems.

Also, you need to make sure that no configuration file will be exposed to web root as it can make them public and eventually an easy prey for hackers to get into the application.

• Using HTTPs

To ensure complete security over internet, HTTPs is a widely known protocol. It guarantees a safe interaction between a user and server, without any third-party interception or change.

If you have developed an application that asks or stores consumers’ sensitive data that they don’t want to make public, it is highly suggested to use HTTPs to deliver the same on server. Such encrypted communications will allow you to refrain your application to leak user data.

In addition to these security practices, you are also recommended to keep software up to date and getting appropriate PHP security tools to avoid websites’ vulnerability in the unsafe digital world.

At last, I am hopeful that you find this article informative and relevant to your PHP web solutions while aiming for a safe digital environment.
