Confidentiality
The concept of the measures used to ensure the protection of the secrecy of data,
objects, or resources.
B-Rate Safe Rating
A catchall safe rating for any box with a lock on it. This rating describes the thickness of
the steel used to make the lockbox. No actual testing is performed to gain this rating.
C-Rate Safe Rating
,This safe rating is defined as a variably thick steel box with a 1-inch-thick door and a
lock. No tests are conducted to provide this rating, either.
UL TL-15 Safe Rating
Safes with an Underwriters Laboratory rating that have passed standardized tests as
defined in Underwriters Laboratory Standard 687 using tools and an expert group of
safe-testing engineers. The safe rating label requires that the safe be constructed of 1-
inch solid steel or equivalent. The label means that the safe has been tested for a net
working time of 15 minutes using "common hand tools, drills, punches hammers, and
pressure applying devices." Net working time means that when the tool comes off the
safe, the clock stops. Engineers exercise more than 50 different types of attacks that
have proven effective for safecracking.
UL TL-30 Safe Rating
This Underwriters Laboratory rating testing is essentially the same as the TL-15 testing,
except for the net working time. Testers get 30 minutes and a few more tools to help
them gain access. Testing engineers usually have a safe's manufacturing blueprints and
can disassemble the safe before the test begins to see how it works.
B. Disclosure
Explanation:
Confidentiality models are primarily intended to ensure that no unauthorized
access to information is permitted and that accidental disclosure of sensitive
information is not possible.
Related to information security, confidentiality is the opposite of which of the following?
A. Closure
B. Disclosure
C. Disaster
D. Disposal
D. All of these
Explanation:
Integrity models keep data pure and trustworthy by protecting system data from
intentional or accidental changes.
Integrity models have which of the three goals:
A. Prevent unauthorized users from making modifications to data or programs
B. Prevent authorized users from making improper or unauthorized modifications
C. Maintain internal and external consistency of data and programs
D. All of these
D. All of these
Explanation:
,Availability models keep data and resources available for authorized use,
especially during emergencies or disasters.
Information security professionals usually address which of these three common
challenges to availability:
A. Denial of service (DoS) due to intentional attacks or because of undiscovered flaws
in implementation (for example, a program written by a programmer who is unaware of
a flaw that could crash the program if a certain unexpected input is encountered)
B. Loss of information system capabilities because of natural disasters (fires, floods,
storms, or earthquakes) or human actions (bombs or strikes)
C. Equipment failures during normal use.
D. All of these
A. Confidentiality, integrity, and availability
Explanation:
These goals form the confidentiality, integrity, availability (CIA) triad, the basis of
all security programs.
Which of the following represents the three goals of information security?
A. Confidentiality, integrity, and availability
B. Prevention, detection, and response
C. People controls, process controls, and technology controls
D. Network security, PC security, and mainframe security
business case
Explanation:
A business case is often made to justify the start of a new project, especially a
project related to security.
Usually a documented argument or stated position in order to define a need to make a
decision or take some form of action.
top-down approach
A type of security management planning where upper, or senior, management is
responsible for initiating and defining policies for the organization.
bottom-up approach
A type of security management planning where IT staff makes security decisions
directly without input from senior management. This approach is rarely used in
organizations and is considered problematic in the IT industry.
Strategic Plan
This security plan is a long-term plan that is fairly stable. It defines the organization's
security purpose. It also helps to understand security function and align it to the goals,
mission, and objectives of the organization. It's useful for about five years if it is
maintained and updated annually. This plan also serves as the planning horizon. Long-
term goals and visions for the future are discussed this plan. This
, plan should include a risk assessment.
Tactical Plan
This security plan is a midterm plan developed to provide more details on accomplishing
the goals set forth in the strategic plan or can be crafted ad hoc based upon unpredicted
events. This plan is typically useful for about a year and often prescribes and schedules
the tasks necessary to accomplish organizational goals. Some examples of these plans
are project plans, acquisition plans, hiring plans, budget plans, maintenance plans,
support plans, and system development plans.
Operational Plan
This security plan is a short-term, highly detailed plan based on the strategic and
tactical plans. It is valid or useful only for a short time. These plans must be updated
often (such as monthly or quarterly) to retain compliance with tactical plans. These
plans spell out how to accomplish the various goals of the organization. They include
resource allotments, budgetary requirements, staffing assignments, scheduling, and
step-by-step or implementation procedures. These plans include details on how the
implementation processes are in compliance with the organization's security policy.
Examples of these plans are training plans, system deployment plans, and product
design plans.
Data classification
Also called classification, the primary means by which data is protected based on its
need for secrecy, sensitivity, or confidentiality. It is the process of organizing items,
objects, subjects, and so on into groups, categories, or collections with similarities.
Five levels of government/military classification
Top secret, Secret, Confidential, Sensitive but unclassified, Unclassified.
Top Secret
The highest level of government/military data classification. The unauthorized disclosure
of top-secret data will have drastic effects and cause grave damage to national security.
This data is compartmentalized on a need-to-know basis such that a user could have
this clearance and have access to no data until the user has a need to know.
Secret
This level of government/military data classification is used for data of a restricted
nature. The unauthorized disclosure of data classified as secret will have significant
effects and cause critical damage to national security.
Confidential
This level of government/military data classification is used for data of a sensitive,
proprietary, or highly valuable nature. The unauthorized disclosure of data with this
classification level will have noticeable effects and cause serious damage to national
security. This classification is used for all data between secret and sensitive but
unclassified classifications.
Sensitive But Unclassified (SBU)
This level of government/military data classification is used for data that is for internal
use or for office use only (FOUO). Often this data classification is used to protect
information that could violate the privacy rights of individuals. This is not technically a
classification label; instead, it is a marking or label used to indicate use or management.
