Web Application Firewalls

Web Application Firewall (WAF) Overview

What are Web Application Firewalls (WAFs)?

Web Application Firewalls (WAFs) hel protect externally-facing web applications. WAFs are part of a layered cybersecurity strategy. It falls to the WAF to prevent zero-day attacks on web apps and APIs that potentially reside in serverless architecture.

In 2006 the Payment Card Industry Data Security Standard (PCI DSS) mandated the protection of applications in production environments with web application firewalls or other devices that provide similar functionality.

Web Application Firewall (WAF) Features & Capabilities


WAFs protect web applications against threats such as:

  • Cross-site scripting

  • SQL injection

  • Session hijacking

  • Denial of service

  • Buffer overflows


WAFs generally present the following features:


  • Libraries of attack data based on known attacks to web applications

  • Monitoring, filtering and blocking of data and access to web applications

  • Automated attack detection, both identity-based (e.g. dynamic whitelisting, fingerprinting, risk scoring) and behavioral (e.g. risk scoring)

  • Advanced security techniques (e.g. deception/misdirection, virtual patch deployment, honeypot)

  • Zero-day attack prevention (related to the above)

  • A management interface with alert system

  • Reporting and analytics on threat and application usage

Pricing Information

The cost of web application firewalls depends on deployment. There are three options:

  1. A managed service or cloud-hosted WAF delivered as part of a subscription. This can be relatively low overhead as part of a larger subscription (e.g. part of a CDN). But it also may contain unneeded features.

  2. A network-based appliance. This presents relatively high overhead but reduces latency because it is installed locally and close to the application.

  3. A host-based WAF residing in the application’s code. This is rarer and may present less desirable computing costs and greater maintenance.
