Almost everyone who decides to establish a ban on access to sites in the "virtual space", faces the same resources. On the first place there are sites of erotic content, followed by online games, virtual casinos, social networks, dating sites, chats.

However, how to prohibit access to the site, if other users of this computer are no less experienced "experts"? In this situation, you have to resort to special programs like a firewall or a specialized filter.

Therefore, the best way to block content is through special programs, where you can set the mask to prohibit the opening of certain resources, not only by IP address, but also by the presence of certain keywords in the name. In addition, similar programs contain a security module, and so you can change the settings only after entering the password.

In conclusion, we note that the choice of a functional solution how to deny access to the site, of course, depends on the network administrator, user skills, the audience, but in any case it is important to choose such a system that will allow complete restriction of access to selected network resources.
