Standard Assignments For System Service Ports; Firewall Configuration - McAfee TSA00M005PAA - Total Protection Service Product Manual

Using Firewall Protection

Firewall configuration

Examples of system services that typically require ports to be opened are:
• Email server — You do not need to open a mail server port to receive email. You need to
open a port only if the computer running firewall protection acts as an email server.
• Web server — You do not need to open a web server port to run a web browser. You
need to open a port only if the computer running firewall protection acts as a web server.
NOTE: An opened service port that does not have an application running on it poses no
security threat. However, we recommend that you close unused ports.

Firewall configuration
Protecting computers from suspicious activity with a firewall involves monitoring network
activity to identify applications, IP addresses, and ports, and blocking those that could cause
harm. There are two methods of establishing firewall protection:
• The administrator configures firewall settings in a Total Protection Service policy.
• Each client computer user configures firewall settings for their computer.
