An appliance or a server plugin or a filter that applies a set of rules to an HTTP conversation is what is known as Web Application Firewall (WAF). These rules generally cover common attacks like cross-site scripting (XSS) and SQL injection. However, you can customize the rules to your application and subsequently identify and block different types of attacks. When it comes to Web Application Firewall, there are different products and solutions available in the market but Imperva’s SecureSphere Web Application Firewall emerges out as one of the best.
Firstly, the Imperva SecureSphere WAF protects your application and data from malicious actors by performing the basic analysis regarding all user access to your business critical web applications. The product then employs machine learning to learn the normal behavior of your applications which is followed by a continuous real time correlation with threat intelligence crowd sourced on a cross country and cross industry scale. Secondly, the SecureSphere WAF then scans for malware in the innocuous looking website traffic. This is one of the critical functions that SecureSphere performs. Nowadays, the threat actors have become smart and do not go for regular patterns which most of the security applications look for. Instead they target the website traffic that looks harmless. In this feature SecureSphere also blocks the different kinds of attacks like SQL injection, remote file inclusion aimed to exploit web application vulnerabilities, cross-site scripting, business logic attacks like botnets, DDoS, site scraping, and comment spam. It also prevents account takeover which ensures that fraudulent transactions are not performed.
One of the key feature of SecureSphere is Dynamic Application Profiling that enables the product to learn all aspects of web applications which includes directories, URLs, and parameters. The Dynamic Application Profiling also helps SecureSphere to keep the legitimate behavior unaffected thereby increasing performance. The other important features include Granular Correlation Policies that reduce false positives, Deep Threat Intelligence that provides threat intelligence in real time and protects from well resources cyber criminals, Virtual Patching that proactively protects web applications from attacks in real time, and an in depth analysis of attacks that helps in providing instant visibility into security, compliance, and content delivery concerns. Imperva’s SecureSphere stands out in competition and boosts the security by providing a robust security framework.
