Summary

This article explains the various security levels available in the Personal Firewall.

System Change

McAfee Personal Firewall security levels allow you to control how much interaction is required to validate communications to and from your computer. When the firewall detects network communication that does not have a rule defined for handling, an alert prompts you to allow or block that communication. The more restrictive a security level chosen the greater the number of rules that are in effect, and more options and alerts are displayed. 

There are 5 levels on the Firewall Security Level page (including Lockdown) 

Security Levels for McAfee Personal Firewall
Security level ranges from Lockdown to Open
Security Levels   Functionality   OTHER
Full Access Y No action is required by user for connections to be allowed.
Outgoing Access (Default level) Y Little or no action is required by user for connections to be allowed. Only inbound events prompt user permission.
Monitored Access Y Alerts allow the user to grant access for application once. Any future changes must be made manually from the Program Permissions pane in MSC.
Stealth Y Blocks all connections you haven’t configured a rule for. This setting is used to hide your computer's presence on the Internet.
Lockdown Y Blocks all connections. This is similar to unplugging the network cable.

You can quickly restore Personal Firewall to its original protection settings.

You can disable Personal Firewall if you do not want to protect your computer from intrusion and unwanted network communication. When Firewall is disabled, you cannot manage inbound or outbound Internet connections.

IMPORTANT: For your protection, McAfee does not recommend disabling the Personal Firewall.

  2. Open the Web and Email Protection drawer.
  3. Click the Firewall link.
