Security is the concern that exists in every digital solution, and it further encourages developers to provide a solution that eliminates every single possibility of malicious attacks in PHP web development.
To make it work developers need to spot the vulnerabilities around the web apps. This blog piece allows you to get a closer look at the ways to secure your PHP allocation from any hackers.
What Security Issues Do We Face In PHP CMS?
PHP is the most famous language for web development. Its popularity has let many bigger brands to integrate this technology into their solutions. But popular CMS such as WordPress, Joomla, Magento, and Drupal also face security issues. Many incidents are occurring in the past suggest that CMS systems are not safe from the security hassles.
The most popular CMS systems like WordPress, Joomla, Magento, and Drupal are built on PHP. As per the reports, most of the vulnerabilities in PHP CMS were caught during the year 2017. Get a quick look at the number of security issues faced by PHP in CMS systems:
- In 2017, WordPress faced security issues rising from 74% to 83%.
- In 2017, Joomla witnessed the security issues dropping to 13.1% compared to 17% in Quarter 3 of 2016.
- In 2017, Magento also experienced the security issues rising a little marginally to 6.5% from 6% in Q3 2016.
- On the flip side, Drupal received a drop in the security issues from 2% in Q3 2016 to 1.6% in 2017.
These figures indicate that security issues can be caught and worked upon. So, web-developers cannot fail to build in any checking or data validation functionality. More flaws let hackers find their sweet spot and exploit the website. Hence, the developers must test and validate every area of PHP security, so nothing can invade the security system.
How to Test PHP Security?
There are various proven code scanner tools available in the market, that can assist the developers to analyze the code quality and security of the PHP applications.
One of the most popular security testing tools is PHP Malware Finder (PMF), which helps developers to find out the malicious codes in the files. Also, they can use RIPS as well, which is a popular code analysis tool, helping developers to code vulnerabilities in real-time.
How to Secure Your PHP Applications from Being Hacked?
There are several ways to secure PHP applications from hackers\' invasion like PHP should be updated regularly, the latest version 7.3.3, and as a developer, you must update your app into this new version. Also, you must update the code and change some functional logic like password hashing.
Below mentioned are some more measures to be taken by the skilled PHP development company:
- Cross-site scripting (XSS)
Cross-site scripting is one of the malicious web attacks, where hackers can inject an external script into the website’s code or output. This attack can get a hold of cookies, sessions, and other sensitive information.
Solution
Developers can remove this by using htmlspecialchars, and they can use ENT_QUOTES, to escape single and double-quotes.
- Use open_basedir
The integration of the open_basedir directive makes the files limited, letting PHP to access the filesystem from the open_basedir directory and downward only.
Solution
In this way, no file or directory outside of that directory can be accessed within the custom PHP web development, and you can secure your web solution.
- Hide Files from the Browser
When you use PHP micro-frameworks, then the specific directory structure lets the placement of files properly. But most of the time, the browser doesn’t process all the files, and they can be seen in the browser.
Solution
Don’t place your files in the root directory but a public folder only. This makes your files inaccessible all the time in the browser.
- Session Hijacking
It is another form of popular attack types in web attack, letting hackers to secretly steal the session ID of the user.
Solution
To prevent session hijacking, developers need to bind sessions to the IP address. Also, they must invalidate the unset cookie, unset session storage, and remove traces faster to avoid the violation, and must try not to expose IDs under any circumstances within the PHP web application development process.
- Upload files in a secured way
The process of file uploading is a necessary part of PHP development, and this process is prone to XSS attacks.
Solution
You can make your custom and ultra-secure file validation rules. Although, some of the frameworks like Laravel, Symfony, and Codeigniter, have their pre-defined methods to validate file types.
- Attack of SQL injection
It is one of the most common types of attack in PHP scripting, where a single query can compromise the complete application and alter the data.
Solution
To avoid this attack, developers must use prepared statements, where PDO helps in securing SQL queries. Also, the integration of ORM like doctrine or eloquent, as it allows the least chances of injecting SQL queries in them.
Some Important Points You Shouldn’t Miss Out While Testing Your PHP Website
When you are ready to test your PHP website, there are a few steps you must keep in mind. Check them out here:
- SSL certificate for HTTPS
It is the best practice to use the HTTPS protocol for web applications. As the HTTPS offers a secured and encrypted accessing channel for untrusted sites. You can easily include HTTPS by adding an SSL certificate to the website.
- Log all errors
After deploying the website on the live server, the next step you must do is to disable the display of errors, as hackers can take some valuable information from these errors. You can log all the errors in a particular file, so it can be used in the future.
- Document root setup
If you want your users to access the website via the browser, then you need to set the document root for PHP applications on var/www/html. On the flip side, if you are developing APIs using frameworks such as Laravel, Symfony, and Slim, you must update the webroot to/public folder.
- Host PHP apps on the cloud server
For a web app, hosting is crucial, but here you need to take some steps, and you should use cloud hosting like DigitalOcean, Linode, AWS. These hosting servers are not just fast and safe, but they are secure as well. They bring a security shield against any malicious phishing or Brute Force attacks on your website.
Conclusion
Security is a process, which needs to be improved and handled with a well-researched approach. When you are ready to face the invasion of hackers with a robust security approach, then you get a well-functioning and much-secured PHP app, which cannot be breached. You should Hire PHP Web Developers from a skilled PHP development company, which can help you attain great accuracy and promptness in your application.
