Website security is the main concern of website owners worldwide. It doesn't matter which framework you use, you should still maintain your web application and server to prevent intrusion. Hackers can attack your website to gain access to sensitive data and use servers to send abused emails and host malicious files.
To prevent security attacks, you can follow the suggestions mentioned below:
1. Keep Software and Framework updated
All software development companies fix security bugs in the latest versions of their products. You can keep hackers away from websites by updating the frameworks and software you use during web development. In this way, you can make your website more secure from attacks. Generally, hackers use security holes in websites to carry out malicious activities. If they can't find the vulnerability, they start finding other websites that have security holes.
2. Use strong and impossible to guess passwords
It is always recommended to use strong passwords for FTP accounts, cPanel, and email accounts to prevent security breaches. You must use lowercase, uppercase, special characters and numbers in your password to make it impossible to guess.
3. Always filter HTML and JavaScript
Cross Site Scripting (XSS) is the most commonly used method for intrusion. Intruders can insert scripted code in web forms or use JavaScript to run malicious code. To ensure security, you should check the submitted data and remove unnecessary HTML tags.
4. Display error messages carefully
When a user enters incorrect login details, a simple error message should be displayed on your website. However, you should be careful about what you will write in this message. Hackers use brute force attack methods to find usernames and passwords. If you display messages like “wrong username” and “wrong password”, hackers will know that their work is half done and can focus on other areas. To stop this, you should use common slogans like “incorrect username or password”. Captcha can also be used on the login page to provide extra security.
5. Use server-side and client-side validation
To prevent malicious data from being entered, you should use both client-side and server-side validation. On the client side, JavaScript can be used for validation, but most browsers offer an option to disable it. Therefore, you should also validate the data on the server to prevent unwanted results on your website.
6. Scan uploaded files
If you offer a file upload facility to allow users to upload their images, you should be careful about what they upload. Hackers can also upload infected files to your server to run malicious code. You cannot rely on file types to prevent attacks. To protect your website, you should check file extensions and change file permissions. For example, if you set chmod 0666, these files will not be executed. You can also store it on a different server by using the Secure File Transport Protocol or the Secure Shell Protocol for secure file transport.
Well, these are some of the security approaches that you can follow to ensure website security. This way, you can keep your website safe from attacks and users can use it without fear.
