WAF Security is a term used to refer to two kinds of Internet security applications: web filtering and network security. Basically, a web filtering application is a kind of program firewall which filters, controls, and monitors HTTP traffic both coming in and going out of a particular web-service. WAF is often used along with a content filtering application. This ensures that web content is acceptable to the various browsers and servers. On the other hand, a WAF is also effective against malicious network code which tries to exploit security vulnerabilities found on the internet.
Another form of WAF is an airlock waf security tool. An airlock is a type of fuzzer/controller which serves a number of purposes. First, it creates a list of “hijackers” to scan for and delete any web services that could be exploited by a hacker, including those running behind the scenes on servers and websites. Second, it creates a list of “known attackers” that can be contacted in order to attack web services associated with that IP address.
