A vulnerability is the absence or weakness of a safeguard or countermeasure.
What security control is directly focused on preventing collusion?
A) Principle of least privilege
B) Job descriptions
C) Separation of duties
D) Qualitative risk analysis
Separation of duties
The likelihood that a co-worker will be willing to collaborate on an illegal or abusive scheme is reduced because of the higher risk of detection created by the combination of separation of duties, restricted job responsibilities, and job rotation.
Data classifications are used to focus security controls over all but which of the following?
Layering is a core aspect of security mechanisms, but it is not a focus of data classifications.

If a security mechanism offers availability, then it offers a high level of assurance that authorized subjects can _________ the data, objects, and resources.
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.
Which of the following is not a defense against collusion?
A) Separation of duties
B) Restricted job responsibilities
C) Group user accounts
D) Job rotation
Group user accounts
Group user accounts allow for multiple people to log in under a single user account. This allows collusion because it prevents individual accountability.
Which of the following is not an element of the risk analysis process?
A) Analyzing an environment for risks
B) Creating a cost/benefit report for safeguards to present to upper management
C) Selecting appropriate safeguards and implementing them
D) Evaluating each threat event as to its likelihood of occurring and cost of the resulting damage
Selecting appropriate safeguards and implementing them
Risk analysis includes analyzing an environment for risks, evaluating each threat event as to its likelihood of occurring and the cost of the damage it would cause, assessing the cost of various countermeasures for each risk, and creating a cost/benefit report for safeguards to present to upper management. Selecting safeguards is a task of upper management based on the results of risk analysis. It is a task that falls under risk management, but it is not part of the risk analysis process.
