Firewall Rules

Overview

A Firewall Rule is used to set up regulations on a particular domain. When a request is made to that domain, the WAF checks for the violation of a rule and carries out the appropriate action that is configured by the User.

The following actions are available to the User :

1. DROP & RECORD REQUEST - If the Request to the subscribed domain matches the Firewall Rule, an event is generated but the request will not be allowed through the WAF.
2. RECORD REQUEST - An event is generated whenever the Request satisfies the Rule, but whenever the request passes through other rules its events are logged by Haltdos.
3. BYPASS REQUEST - If the Request tests positive for the rule, no other rule is tested and the Request will be allowed through the WAF.
4. REDIRECT - If the request satisfies the rule, then the user is redirected to another page.
5. NO ACTION - If the request satisfies the rule, then no action will be performed on the current request.

How to Use:

1. Log onto the Haltdos Community WAF portal.
2. Go to WAF > Rules > Firewall Rules.
3. Click on the Add Rule Button and a pop-up box will open.
4. Configure the fields that are present.
5. Click on Save Changes and the rule will be reflected.
