Application Security

A web application firewall (WAF) protects applications and APIs. WAFs are usually placed in front or before web-facing applications to detect and protect against a variety of malicious attacks. A WAF is focused on web application traffic (HTTP/S) and protects applications in internet-facing zones of the network.

Transitioning from a traditional WAF to WAAP and augmenting your application security posture with RASP is the recommended best practice for most organizations. This protects individual applications from certain threats using RASP while protecting all web-facing applications using a WAF or WAAP.

Today, there are many pricing and licensing models for organizations to choose from – perpetual pricing per instance, subscription pricing by instance, by throughput, per-user, by CPU cores, metered pricing based on consumption, bring-your-own license (BYOL), pay-as-you-go (PAYG) consumption and service provider-licensing agreements (SPLA) etc.

Web shells are malicious script files that provide read, write, and/or execution capabilities to a hacker.

WebSockets simplify the communication between browsers and servers by overcoming some of the traditional restrictions.

Web application firewall (WAF) rules are used to define how to inspect HTTP/HTTPS web traffic (requests) to an application, where and what parameters and conditions to look for in the request, and what action the WAF should take when a request matches those definitions.

A positive security model is one that defines what is allowed and rejects everything else. It is in contrast to a negative security model that defines what is disallowed, while implicitly allowing everything else.

A Web Application Firewall is a security tool that protects web applications and APIs from malicious requests and cyber attacks. WAFs are a critical defense for enterprises and online businesses that need to protect sensitive data. WAFs work by analyzing each HTTP/S request and blocking or filtering out any malicious requests. WAFs can also help with load balancing and provide visibility into web traffic.
