HOWTO: Method for Weighting Library Categories

Expand / Collapse
Show/Hide Article Tools


This article applies to:

  • All version of the R3000 filtering units.

Question:

  • How does the method of weighting categories works?

Procedure:

The order of operational precedence is: Always Allowed,

Blocked, and Pass.

In the event that an end user attempts to access a URL that

exists in multiple categories, the highest operational precedence

would be logged.

If a URL exists in a category that is Always Allowed, as well

as a category set to be Blocked for that user, Always

Allowed would be logged because it holds the highest operational

precedence.

However, if an end user attempts to access a URL set to be

Blocked in several categories, the category with the highest

weighting would be logged.

Notes:  

If a URL exists in multiple un-weighted categories of the

same operational precedence, the category logged would be the

first one returned by the R3000 database. Since there is no

precedence given, the order in which the category is returned

would be random. While it is not necessary to weight all categories,

it is recommended that the categories considered a threat

should be weighted according to your organization's threat

assessment for each category
