Web Application Firewall! (WAF)

Intro:

A web application firewall (WAF) is an appliance, server plugin, or filter that applies a set of rules to an HTTP conversation. Generally, these rules cover common attacks such as cross-site scripting (XSS) and SQL injection. By customizing the rules to your application, many attacks can be identified and blocked. The effort to perform this customization can be significant and needs to be maintained as the application is modified.

• Network-Based Application Firewalls

A network-based application layer firewall application layer protocol stack operating in a computer network firewall, and a proxy or reverse proxy-based firewall is known as. A special type of network traffic specific application firewalls as a web application firewall, the service can be titled with the name. They have a host or network hardware to run the software on a stand-alone piece that can be implemented through. Often, the client or server proxy traffic before passing it on to the proxy server host using different forms. Because it works on the application layer, such as certain websites, viruses, or client software attempts to exploit known logical flaws as specific content, blocking traffic, inspect the contents of the can .

• Specialized Application Firewalls

Specialized application firewalls offer a rich feature-set in protecting and controlling a specific application. Most specialized network appliance application firewalls are for web applications.

• Distributed Web Application Firewalls

Distributed Web (also called a dwarf) Application Firewall Web Application Firewall (WAF) and technology Web applications security is a family member. Purely software-based, plant architecture in different parts of the network are physically able are designed as separate components. This advance in architecture allows complete independence as required scale of resource consumption while sowing, instead of relying on a tool to be spread across a network allows. In particular, it independently of each other for better resource management of any number of components in addition / subtraction allows. This approach, like the private public or hybrid cloud model as large and is ideal for distribution are virtualized infrastructure.

• Cloud-Based Web Application Firewalls

Cloud-based web application firewall is also member of the web application firewall (WAF) and web applications security family of technologies. This technology is unique due to the fact that it is platform agnostic and does not require any hardware or software changes on the host. All providers but one require a DNS change, wherein all web traffic is routed through the WAF where it is inspected and threats are thwarted. Cloud-based WAVEs are typically centrally orchestrated, which means that threat detection information is shared among all the tenants of the service. This collaboration results in improved detection rates and lower false positives. Like other cloud-based solutions, this technology is elastic, scalable and is typically offered as a pay-as-you grow service. This approach is ideal for cloud-based web applications and small or medium-sized websites that require web application security but are not willing or able to make software or hardware changes to their systems.
