WAFs are key in making an organization’s security stronger, whether they’re used directly or as a middleman. They help protect web apps from many threats and make sure they follow the latest rules⁸.

WAF Types: Understanding the Different Varieties

Web application firewalls (WAFs) are key tools for boosting web security. They’ve been around since the late 1990s, aiming to shield web applications from various threats¹⁰. The OWASP Top 10 list sets the standard for web security, as web app attacks lead to many data breaches¹⁰. WAFs are made to protect against common threats like injection attacks and poorly designed apps¹⁰.

Network-Based WAFs

Network-based WAFs sit at the network level, checking and filtering traffic between the web app and the internet¹¹. They can catch and block a wide range of web app risks, including OWASP Top 10 threats like injection attacks and broken authentication¹⁰¹¹.

Host-Based WAFs

On the other hand, host-based WAFs are on the web server, offering protection at the application layer¹¹. They look at web app traffic and enforce security rules to fight off DDoS attacks and other top threats from the 2021 OWASP Top 10 list¹⁰. Host-based WAFs give a closer look at web app traffic, attack attempts, and security actions for auditing and meeting compliance¹⁰.

Knowing about the different WAF types and what they do is key for boosting web security. Whether it’s network-based or host-based, the right WAF can shield web apps from many online dangers¹⁰¹¹.

Feature	Network-Based WAF	Host-Based WAF
Deployment	Deployed at the network level, monitoring traffic between the application and the internet	Installed directly on the web server, providing protection at the application layer
Security Focus	Protects against a wide range of web application vulnerabilities, including OWASP Top 10 risks	Focuses on mitigating specific threats like DDoS attacks and cryptographic failures
Visibility and Logging	Provides visibility and logging of web application traffic, attack attempts, and security measures	Offers a more granular level of control and visibility, with detailed logging for auditing and compliance

Choosing between network-based and host-based WAFs depends on what an organization needs for its web security¹⁰¹¹.

Deploying WAFs: Best Practices for Implementation

Deploying and configuring web application firewalls (WAFs) right is key to making them work best for web security. Businesses should follow best practices for WAF setup¹².

First, update the WAF regularly to keep up with new threats and weaknesses. Cybercriminals keep changing their ways, so an updated WAF can defend against new attacks¹².

It’s also important to adjust the WAF rules for your specific needs and web apps. This way, you avoid false alarms and let in good traffic while keeping out bad traffic¹².

Working the WAF with other security tools, like SIEM systems, gives you a stronger defense. This lets you check security logs, spot oddities, and act fast on threats¹².

Finally, always keep an eye on how the WAF is doing. Look at the logs to find ways to get better, tweak the rules, and keep your web apps safe¹².

Using these best practices for WAF setup can make your web application firewalls work better. It boosts your web security¹².

WAF Deployment Best Practices	Description
Regular Updates	Regularly update the WAF solution to address the latest threats and vulnerabilities¹².
