Figure 12.9 ISS OrangeWeb Filter categories

Note:

1. You can deﬁne multiple URL rules that will use the ISS OrangeWeb Filter rating technology.

Multiple categories may be used for each rule.

2. We recommend you to unlock rules that use the ISS OrangeWeb Filter rating system (the

Users can Unlock this rule option in the Advanced tab). This option will allow users to

unlock pages blocked for incorrect classiﬁcation. All unlock queries are logged into the

Filter log — here you can monitor whether unlock queries were appropriate or not.

12.5 Web content ﬁltering by word occurrence

WinRoute can also ﬁlter Web pages that include undesirable words.

This is the ﬁltering principle: Denied words are matched with values, called weight (repre-

sented by a whole positive integer). Weights of these words contained in a required page are

summed (weight of each word is counted only once regardless of how many times the word is

included in the page). If the total weight exceeds the deﬁned limit (so called treshold value),

the page is blocked.

So called forbidden words are used to ﬁlter out web pages containing undesirable words. URL

rules (see chapter 12.2) deﬁne how pages including forbidden content will be handled.
