🛠 Common Website Security Risks to Watch For
Understanding the threats is the first step to prevention.
1. SQL Injection
Attackers inject malicious code into forms to access your database.
2. Cross-Site Scripting (XSS)
Hackers add scripts into your website that execute in users’ browsers.
3. Cross-Site Request Forgery (CSRF)
Tricks users into executing unwanted actions on your site while logged in.
4. Insecure File Uploads
Malicious files can give hackers access to your server.
5. Outdated Software
Using outdated plugins, themes, or CMS versions is like leaving the backdoor open.
✅ Best Practices for Secure Web Development
Here’s how to keep your site locked down and users protected:
1. Use HTTPS with SSL
-
Install an SSL certificate
-
Redirect HTTP to HTTPS
-
Google penalizes non-HTTPS sites
2. Sanitize & Validate All User Input
-
Prevent SQL injection and XSS
-
Use built-in functions or frameworks like Laravel, Django, or Express
3. Use Parameterized Queries
Especially in PHP, Python, or Node.js to prevent database vulnerabilities.
4. Enable CSP (Content Security Policy)
-
Prevents XSS by controlling which resources load on your site
5. Limit File Upload Types
-
Allow only safe formats (like .jpg, .pdf)
-
Use virus scanners on uploaded files
6. Keep Software Updated
-
Always update WordPress, plugins, and themes
-
Use reliable themes from trusted developers
7. Limit Login Attempts
8. Secure Admin Directories
-
Rename or hide wp-admin/login URLs
-
Use two-factor authentication (2FA)
9. Use Strong Passwords
-
Enforce password policies
-
Use tools like LastPass or Bitwarden
10. Set Proper File Permissions
-
644 for files
-
755 for folders
-
Deny access to sensitive files like .env or wp-config.php
