Driven by the need to meet PCI DSS regulatory standards and the integration of security functionalities, the web application firewall market is set to increase at a compound annual growth rate (CAGR) of 18.34% through 2016.
Hackers are increasingly focusing on attacking application layers rather than network layers. DoS is one of the most common and age-old techniques that helps carry out confidential data theft. Hackers use DoS to flood a web server's computing and network resources with data, thereby increasing the traffic.
This automatically generates several requests for access. As a result, the server ends up blocking access for legitimate users.
However, hackers these days are opting for DDoS techniques, which are improved versions of DoS. While using the DDoS technique, the hacker initiates a coordinated attack from multiple systems, which is more powerful than DoS.
Enterprises are increasingly becoming dependent on websites and web applications, which has led to the subsequent increase in the number of security threats.
Hence, to secure the transactions that are carried out using websites and web applications, regulatory authorities in various countries have revamped their PCI DSS regulations for companies that operate in the E-commerce sector.
A web application firewall (WAF) is an appliance, server plug-in, 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 customisation can be significant and needs to be maintained as the application is modified.
A major challenge currently facing the web application firewall market is the increase in false-positive risks. The number of security threats has been constantly increasing, along with the increase in the number of websites and web-based applications.
Key companies currently dominating the web application firewall market include Cisco Systems Inc., Citrix Systems Inc, F5 Networks Inc., Fortinet Inc., Imperva Inc., Juniper Networks Inc., and Palo Alto Networks Inc.
