antara lain mengindetifikasikan sebuat website merupakan content
management system atau cms, serta mengindentifikasi blogging
platforms, statistic/analytics packages, JavaScript libraries, web
servers, dan embedded devices. Pernyataan pendukung dari developer WhatWeb
mengatakan bahwa :
“ WhatWeb can be stealthy and fast, or thorough but slow. WhatWeb supports an aggression level to control the trade off between speed and reliability. When you visit a website in your browser, the transaction includes many hints of what web technologies are powering that website. Sometimes a single webpage visit contains enough information to identify a website but when it does not, WhatWeb can interrogate the website further. The default level of aggression, called ‘passive’, is the fastest and requires only one HTTP request of a website. This is suitable for scanning public websites. More aggressive modes were developed for in penetration tests.”
Hal di atas tersebut menjelaskan WhatWeb
mengindetifikasi teknologi dari sebuah website yaitu informasi penting yang mendukung sebuah website tersebut.
