To define a new service, first you must determine which port number or range of numbers is used
by the application. This information can usually be determined by contacting the publisher of the
application or from user groups of newsgroups. When you have the port number information, you
can enter it on the Services screen.
To add a customized service:
1. Select Security from the main menu and Services from the submenu. The Services screen will
display.
Figure 4-17
2. In the Add Custom Service table, enter a descriptive name for the service (this is for your
convenience).
3. Select the Layer 3 Protocol that the service uses as its transport protocol. It can be TCP, UDP
or ICMP.
4. Enter the first TCP or UDP port of the range that the service uses. If the service uses only one
port, then the Start Port and the Finish Port will be the same.
5. Enter the last port of the range that the service uses. If the service only uses a single port
number, enter the same number in both fields.
6. Click Add. The new custom service will be added to the Custom Services Table.
