B. Violations of confidentiality include management oversight.
C. Violations of confidentiality are limited to direct intentional attacks.
D. Violations of confidentiality can occur when a transmission is not properly encrypted.
Answer: C
Violations of confidentiality are not limited to direct intentional attacks. Many instances of unauthorized disclosure of sensitive or confidential information are due to human error, oversight, or ineptitude.
- STRIDE is often used in relation to assessing threats against applications or operating systems. Which of the following is not an element of STRIDE?
A. Spoofing
B. Elevation of privilege
C. Repudiation
D. Disclosure
Answer: D
Disclosure is not an element of STRIDE. The elements of STRIDE are spoofing, tampering, repudiation, information disclosure, denial of service, and elevation of privilege.
- If a security mechanism offers availability, then it offers a high level of assurance that authorized subjects can ___________ the data, objects, and resources.
A. Control
B. Audit
C. Access
D. Repudiate
Answer: C
Accessibility of data, objects, and resources is the goal of availability. If a security mechanism offers availability, then it is highly likely that the data, objects, and resources are accessible to authorized subjects.
- _________ refers to keeping information confidential that is personally identifiable or which might cause harm, embarrassment, or disgrace to someone if revealed.
A. Seclusion
B. Concealment
C. Privacy
D. Criticality
Answer: C
Privacy refers to keeping information confidential that is personally identifiable or which might cause harm, embarrassment, or disgrace to someone if revealed. Seclusion is to store something in an out of the way location. Concealment is the act of hiding or preventing disclosure. The level to which information is mission critical is its measure of criticality.
- All but which of the following items require awareness for all individuals affected?
A. Restricting personal email
B. Recording phone conversations
C. Gathering information about surfing habits
D. The backup mechanism used to retain email messages
Answer: D
Users should be aware that email messages are retained, but the backup mechanism used to perform this operation does not need to be disclosed to them.
- What element of data categorization management can override all other forms of access control?
A. Classification
B. Physical access
C. Custodian responsibilities
D. Taking ownership
Answer: D
Ownership grants an entity full capabilities and privileges over the object they own. The ability to take ownership is often granted to the most powerful accounts in an operating system because it can be used to overstep any access control limitations otherwise implemented.
- What ensures that the subject of an activity or event cannot deny that the event occurred?
A. CIA Triad
B. Abstraction
C. Nonrepudiation
D. Hash totals
Answer: C
Nonrepudiation ensures that the subject of an activity or event cannot deny that the event occurred.
- Which of the following is the most important and distinctive concept in relation to layered security?
A. Multiple
B. Series
C. Parallel
D. Filter
Answer: B
Layering is the deployment of multiple security mechanisms in a series. When security restrictions are performed in a series, they are performed one after the other in a linear fashion. Therefore, a single failure of a security control does not render the entire solution ineffective.
- Which of the following is not considered an example of data hiding?
A. Preventing an authorized reader of an object from deleting that object
B. Keeping a database from being accessed by unauthorized visitors
C. Restricting a subject at a lower classification level from accessing data at a higher classification level
D. Preventing an application from accessing hardware directly
Answer: A
Preventing an authorized reader of an object from deleting that object is just an example of access control, not data hiding. If you can read an object, it is not hidden from you.
14 What is the primary goal of change management?
A. Maintaining documentation
B. Keeping users informed of changes
C. Allowing rollback of failed changes
D. Preventing security compromises
Answer: D
The prevention of security compromises is the primary goal of change management.
- What is the primary objective of data classification schemes?
A. To control access to objects for authorized subjects
B. To formalize and stratify the process of securing data based on assigned labels of importance and sensitivity
C. To establish a transaction trail for auditing accountability
D. To manipulate access controls to provide for the most efficient means to grant or restrict functionality
Answer: B
The primary objective of data classification schemes is to formalize and stratify the process of securing data based on assigned labels of importance and sensitivity.
