Web application objects
Use web application objects to control access to categorized types of web-based applications and to control how people use them on your network.
The Network Security database provides an indexed list of web application categories that you can block or limit access to on your network. These categories include pornography, web mail, social networking, gaming sites, and many more.
In addition to blocking or limiting these site categories, you can prohibit users from performing specific actions on many of these sites. For example, you can allow users to view social media sites such as YouTube or Flickr, but not allow users to post to them. Or you can allow users to view and to post to networking sites, such as Facebook or Myspace, but not to upload photos or to play games.
