Infrastructure Security: System Hardening • Chapter 8 501

Service Packs

■ Service packs for various application servers are produced nearly as often
as those for OSes and NOSes.

■ Expect to see service packs or major collections of hotfixes, provided at
fairly regular intervals.

■ Service packs may be utilized often to correct the initial problems discov-
ered since the product’s release.

Patches

■ Patches for application servers are provided by the vendor of the product.

■ Patches are used to fix compatibility and minor operation issues and inter-
face problems.
■ Accumulations of patches are sent out as service packs.

EXAM WARNING
The Security+ exam contains questions about the additional security
configurations required for most of the application servers discussed. Be
sure to review the potential vulnerabilities of the various server types
and the manufacturer-recommended security plans for them. For
example, you may want to review settings relative to e-mail servers on
disabling e-mail relay problems, FTP servers for restricting access, Web
servers for restricting access, and database servers for protecting the
databases and structure.

Web Servers

Most companies and organizations today have a Web presence on the Internet.An
Internet presence offers numerous business advantages, such as the ability to adver-
tise to a large audience, to interact with customers and partners, and to provide
updated information to interested parties.
