Cross-Site Scripting (XSS)

Cross-site scripting (XSS) attacks involve injecting malicious scripts into web pages viewed by users. These scripts can hijack user sessions or redirect them to dangerous sites.

To defend against XSS:

• Validate and sanitize user inputs
• Implement Content Security Policies (CSP)
• Regularly scan for vulnerabilities

File Inclusion Exploits

File inclusion exploits occur when an attacker includes a file on the web server through the browser’s URL parameter. This vulnerability can lead to Remote Code Execution (RCE), allowing hackers to control your site entirely.

Protective actions:

• Disable remote file inclusion
• Validate file paths and names
• Configure server settings securely

Understanding these common security risks helps build a more robust defense strategy for your CMS-based website.

Best Practices for Securing Your WordPress Website

Securing your WordPress website is crucial to protect it from potential threats and vulnerabilities. Implementing a layered security approach can greatly enhance your site's defenses. Here are some best practices:
