If your website handles user data, payments, or login credentials, running a website security audit is not optional—it’s essential. From WordPress blogs to custom-built web apps, every website faces risks that can be exploited without proper precautions.
This guide will walk you through how to perform a full web application security audit, what tools to use, and how to fix common issues before they’re exploited.
What Is a Website Security Audit?
A website security audit is a detailed evaluation of your website’s security posture, identifying vulnerabilities in:
- Code (plugins, themes, frameworks)
- Server configuration
- Authentication and session management
- User input handling (to prevent SQLi, XSS, etc.)
- Exposure to known exploits (CVEs)
It’s the first step in building a strong, proactive defense strategy.
When Should You Run a Security Audit?
- Before launching a new website or web app
- After major code or plugin updates
- If you suspect a breach or data leak
- Quarterly, as part of routine security maintenance
Regular auditing is especially important for sites built on popular platforms like WordPress, where plugin vulnerabilities are common.
Key Areas in a Web Application Security Audit
1. Input Validation & Output Encoding
- Check for XSS, SQL injection, and CSRF risks
- Test all forms, comment boxes, and URL parameters
2. Authentication & Access Control
- Enforce strong passwords and 2FA
- Prevent privilege escalation
- Review session timeout settings
3. Configuration & Deployment
- Remove default credentials and sample files
- Disable unnecessary services or ports
- Use HTTPS and secure headers (CSP, HSTS, etc.)
4. Plugin & Component Analysis
- Identify outdated or vulnerable components
- Use scanners like PressVuln.com to audit WordPress sites for plugin and theme issues
Tools for Website Security Audits
- OWASP ZAP or Burp Suite – for in-depth app testing
- WPScan – to audit WordPress for known plugin/theme vulnerabilities
- Nikto – scan for insecure server configurations
- PressVuln.com – quickly identify outdated WordPress components and known CVEs
