An Introductory Guide To Web Application Firewall

Similar to Dr. Stephen Strange's powerful Shields of Seraphim, Web Application Firewalls (WAFs) act as a protective barrier between web applications and online threats. This article explores how WAFs function, their evolution, advantages, and future prospects in safeguarding businesses from the perils of the internet.

While most of us can't be as formidable as Dr. Strange, we can still deploy our version of protective barriers with Web Application Firewalls (WAFs). WAFs, akin to Dr. Strange's Shields are tailored firewalls designed for web applications. Positioned in front of these applications, they scrutinize bidirectional web traffic over HTTPS, shielding against cyber threats. This article delves into what WAFs are, their functionality, significance for businesses, and how they're more akin to Dr. Strange's powers than one might realize. If your IT woes are supernatural, Dr. Strange is your guy; for the digital realm, it's WAFs.

Understanding Web Application Firewalls (WAFs)

Web Application Firewalls (WAFs) serve as the virtual equivalent of Dr. Strange's fire-walls, safeguarding web applications by monitoring and filtering HTTP traffic between the application and the Internet. They effectively shield enterprise infrastructures from a range of malicious threats, including cross-site forgery, cross-site scripting, and SQL injection. WAFs have evolved over time and come in various forms, including network-based, host-based, and cloud-based, tailored to specific business needs. This article explores the history and development of WAF technology.
