Creating Content Filtering Rules

This article is for IT support and filtering administrators.

 A basic set of rules have been set up by Linewize Support to protect your users from the risky content. You add content filtering rules and move them up or down in priority to help your users avoid additional inappropriate content. Filtering rules can also be used to limit users to specific allowed content or to allow websites to some groups and not others.

  1. In School Manager, select Filtering > Content Filtering.
  2. You will see your current list of Content Filtering Rules.
  3. To add a new rule, select Add Rule.
  4. Configure the following settings:

Name

The best practice for naming a rule is to give it something that’s both short and descriptive, covering what the rule is intended to do and who it applies to. We recommend following this naming convention: Block/Allow - Signature/Category - Scope

Type: Website/Category

You can select Signature, Custom List or Website for your rule from the drop-down list. If you are unsure of the Signature of the website you want to block, or the category of the signature you want to block, use the Signature/Category Search function.

Type: Select Criteria

This will define to whom the rule will apply. Using this feature you can fine-tune the level of control by including or excluding different criteria. Select a Criteria using the drop-down.

Warning

If you select multiple criteria for a Rule, it will make an AND Rule. For example, If you select a Group and Network criteria for a rule, the rule would only apply to users who are both in the selected group and on the IP subnet.

Actions (Rule Types)

At the most basic level, School Manager allows you to create four types of Content Filtering Rules or actions.

Redirect & Redirect URL

This option only applies to a Block rule.

You can redirect the user to your chosen URL when they conflict with a rule. 

You cannot enable this if you have enabled a Block page for this rule.

Blocked Page

This option only applies to a Block rule

You can enable a Block page when a user conflicts with a rule. 

You can use the default block page or create your own.

Alert

This option only applies to a Block rule
Enable this feature to receive filtering alerts. You will also need to configure the Emailed Reports section. Go to Filtering > Reports and Alerts.

Quarantine

This option only applies to a Block rule and should only be used when Blocking a Proxies & VPNs Signature.
This feature allows you to temporarily block users attempting to access this content from all internet traffic for 3 minutes. For more information please read Using Quarantine.

Locked Rule

For Blocked: The Signature/Category is Blocked and can’t be accessed, even if another Rule is set to Allow. Teachers using Classwize can’t override this by using a bypass code, classroom rule or reward.
For Allowed: The Signature/Category is Allowed and can always be accessed, even if another Rule is set to Block. Teachers using Classwize can’t override this by creating a block or focus rule, but can temporarily block access to all internet traffic, including Locked Allowed sites, by using Pause Internet.

Tip

To give teachers the most autonomy in managing their classes, it is recommended to only Lock those rules which are absolutely required to be blocked or allowed.


About Website/Category Types

Type (Website/Category)

Description

Instructions

Signature/Category

You can select from a predefined list of Signatures or Categories. Signatures are a pattern or fingerprint that School Manager can use to identify a specific website, service, or application. A Category is a collection of Signatures and websites that fit the category. All websites will have a category (eg: Social Media, Online Shopping, etc), but not all sites and applications will have a signature (eg: Facebook, YouTube, etc); signatures are usually only created for very popular sites and applications, or ones that may need special treatment.

See Filtering Using Categories and Signatures for more information.



  1. When creating the Rule, type in a Signature, for example, Business and Government
  2. Select Signature Business and Government from the list.


Custom List

By using the Object Pools feature, you can create an editable list of domains which is called an Object Pool or Custom List.


  1. Select Configuration > Objects > Pools
  2. Create a Block List Domains object pool and add websites to this list.
  3. When creating the Rule, search for the Block List Domains
  4. Select Custom Website List - Block List Domains from the list.


Website

You can enter individual domain names.


  1. When creating the Rule, type in a domain name, for example, facebook.com
  2. Select Website facebook.com from the list.
