Top Web Application Firewall (WAFs) to Stop Website Attacks

Web Application Firewalls (WAFs) are required to keep your web application secure from various types of threats. Web Application Firewalls (WAFs) are designed to protect Web Applications from vulnerabilities, including  Malicious attacks, Cross-Site scripting, SQL injection, DDoS attacks, request forgeries and much more. There are two different types of Web Application Firewalls (WAFs) available- Cloud-based and Integrated.

Hardware and Integrated Web Application Firewalls (WAFs)  are complex and require an expert to configure and maintain them. WAF protection is not merely a one-time configuration, it requires ongoing maintenance. Cloud-based Web Application Firewalls (WAFs)  are simple to use and configure, no maintenance is required and this option is cost effective too.

The Open Web Application Security Project (OWASP) is an online community that creates documentation, tools, and technologies for web application security.

Below are the top 10 threats listed by OWASP:

  • Injections
  • Broken Authentication and Session Management
  • Cross-Site Scripting (XSS)
  • Insecure Direct Object References
  • Security Misconfiguration
  • Sensitive Data Exposure
  • Missing Function Level Access Control
  • Cross-Site Request Forgery (CSRF)
