Web Filtering 29
Web Filtering Management
The process of configuring Web Filtering policies requires the use of several
“filtering objects.” Each of these objects is listed in the left hand column under the
Management box. These objects are:
• Schedules
• Policies
• Quotas
• Global Settings
Filters – Each filter consists of the following objects:
• Filtering Category
• Domains/URL
• Content Types
• File Types
• Exceptions
Schedules – This is a pre-defined period of time and days, based on a 7-day
week and a 24-hour clock. Schedules are defined globally, but can be assigned
and “re-used” within any Policy.
Policies – A policy is a series of rules consisting of a ‘WHO’ filter, a ‘WHAT’ filter
and a ‘WHEN’ filter, as well as the action to take if this rule is matched. Rules can
be active or inactive and can be reordered within the policy.
Groups – A group is a collection of users who share similar web access
privileges. A group can be defined using directory information, such as directory
group or username, or by network parameters such as IP address or subnet.
Quotas – A quota is an administrator defined parameter that limits user web
usage, typically by time spent “surfing” or by bytes downloaded. Quotas are
defined “globally”, but are enforced by assigning them to specific Policies. Note
that this functionality requires the Connector to be installed.
Each of these objects is defined specifically for each filter; however, you can copy
from the default filter into other filters if you so choose.
Each of these objects will be discussed in further detail below.
Filters
A ‘Filter’ is a set of user-defined web filtering components. These components will
have an action associated with them in the Policy rule (e.g. either Allow or Block).
These filters are broken down into five different components:
