Q

Computer Emergency Response Team (CERT)

A

After the Morris worm incident, the U.S. government recognized the need for a public
or private entity to deal with incident coordination, response, and remediation efforts
during Internet security situations. The U.S. government contracted Carnegie Mellon
University to create a Computer Emergency Response Team (CERT) in 1988. The
team’s objective was to ensure that appropriate technology and systemsmanagement
practices resisted attacks on networked systems, limited damage, and
ensured continuity of critical services in spite of successful attacks, accidents, or
failures. The team also provided information on industry trends and educated
individuals and partners on security issues.

International Information Systems Security Certification Consortium, Inc. (ISC)2

A

established in 1989 as a nonprofit corporation to educate and to certify information
security professionals. Certifications offered included the Certified Information
Systems Security Professional (CISSP) certification. In 1990, (ISC)2 created the first
prototype for the Common Body of Knowledge (CBK) criteria. CBK defines global
industry standards and serves as a common framework of terms and principles
within the information security industry.

user accounts. This hive is independent of the
specific user application settings, unlike HKCU
and HKU. This is also where the five registry
hives are located: Security Accounts Manager
(SAM), Security, Software, Default, and
Hardware. This is the most important registry root
key. If SAM or any of the other hives is not

displayed and the computer will not be able to
boot into the OS until the missing hive is replaced.

61
Q

HKEY_USERS (HKU)

A

The key stores configuration information for all
user profiles. If the computer is on a domain, the

62
Q

HKEY_CURRENT_CONFIG

HKCC

A

The key stores the current hardware profile.

more reliable, includes fault tolerance, and keeps track of
hard disk errors. It also maintains transaction logs, which is
an important feature because it helps in recovering files in
case the hard disk crashes.

77
Q

*nix

A

*nix is a colloquial expression that represents either the Unix
or Linux operating system. This terminology can be applied
to variants of both Unix and Linux to include FreeBSD,
Solaris, Ubuntu, Debian, Slackware, and Gentoo. The
underlying reason why *nix represents both operating
systems is because the two share similar functionality as an
operating system, including utilizing similar kernels, shell
commands, system permissions, and file systems.

78
Q

Open Source Software

A

e Open source software is freely distributable software, which
in most cases allows the user access to the source code.
Open source software must meet specific criteria to be
copyrighted under the GNU public license
