Comodo Endpoint Security Manager - SME - Administrator Guide

• Alert Settings

General Settings

In the General Settings tab, an administrator can customize firewall security by using the Firewall Security Level slider to change

preset security levels.

The choices available are:

• Block All

• Custom Policy

• Safe Mode

• Training Mode

• Disabled

• Block All Mode: The firewall blocks all traffic in and out of a computer regardless of any user-defined configuration

and rules. The firewall does not attempt to learn the behavior of any applications and does not automatically create

traffic rules for any applications. Choosing this option effectively prevents a computer from accessing any networks,

including the Internet.

• Custom Policy Mode: The firewall applies ONLY the custom security configurations and network traffic policies

specified by the administrator. New users may want to think of this as the 'Do Not Learn' setting because the firewall

does not attempt to learn the behavior of any applications. Nor does it automatically create network traffic rules for

those applications. The user will receive alerts every time there is a connection attempt by an application - even for

applications on the Comodo Safe list (unless, of course, the administrator has specified rules and policies that instruct

the firewall to trust the application's connection attempt).

If any application tries to make a connection to the outside, the firewall audits all the loaded components and checks

each against the list of components already allowed or blocked. If a component is found to be blocked, the entire

application is denied Internet access and an alert is generated. This setting is advised for experienced firewall users

that wish to maximize the visibility and control over traffic in and out of their computer.

• Safe Mode: While filtering network traffic, the firewall automatically creates rules that allow all traffic for the

components of applications certified as 'Safe' by Comodo, if the checkbox Create rules for safe applications is

selected. For non-certified new applications, the user will receive an alert whenever that application attempts to access
