services, in addition to the basic ones described in the pre-
vious section, that expand what you allow in and out of
your firewall.
Every service brings trade-offs between network security
and accessibility. When selecting services, balance the
needs of your organization with the requirement that com-
puter assets be protected from attack. Some common ser-
vices that organizations typically add, in addition to the
ones listed in the previous section, are HTTP (Internet ser-
vice) and SMTP (email service). Generally, in a new setup,
it is recommended that you use only filtered services until
all your system are functional, and then move to proxies as
you become familiar with them, as needed.
For more information on services, see Chapter 8, "Config-
uring Filtered Services", and Chapter 9, "Configuring
Proxied Services."
