11.4 Summary
Connecting to a network opens up a whole new set of security
considerations above and beyond those of protecting accounts and
files. Various forms of network protocols, servers, clients, routers,
and other network components complicate the picture. To be safely
connected requires an understanding of how these components are
configured and how they interact.
Connections to networks with potentially unfriendly users should be
done with a firewall in place. Connections to a local area network
that involves only your company or university may not require a
firewall, but still requires proper configuration and monitoring.
In later chapters we will discuss some of these other considerations.
We cannot provide truly comprehensive coverage of all the related
issues, however, so we encourage you to peruse the references listed
in Appendix C.
