1What is the primary purpose of implementing defense in depth in an information security program?

A.To eliminate all security vulnerabilities in the network

B.To provide multiple overlapping layers of security controls

C.To reduce the overall cost of security implementations

D.To simplify security policy management

Explanation: Defense in depth is a security strategy that employs multiple overlapping layers of security controls throughout an IT system. The goal is not to eliminate all vulnerabilities (impossible) but to ensure that if one control fails, others are in place to protect assets. This layered approach provides redundancy and makes it significantly harder for attackers to compromise systems. Each layer provides a barrier that must be overcome, buying time for detection and response.

2Which access control model grants permissions based on a user's role within an organization?

A.Discretionary Access Control (DAC)

B.Mandatory Access Control (MAC)

C.Role-Based Access Control (RBAC)

D.Attribute-Based Access Control (ABAC)

Explanation: Role-Based Access Control (RBAC) assigns permissions to users based on their organizational role (e.g., manager, accountant, IT administrator). Permissions are associated with roles, and users are assigned to appropriate roles. This simplifies administration as permissions are managed at the role level rather than individually. DAC allows resource owners to control access, MAC uses security labels and clearances, and ABAC uses attributes of users, resources, and environment.

3An organization wants to implement an access control system that evaluates attributes of the user, resource, and environment to make authorization decisions. Which model should they implement?

A.Mandatory Access Control (MAC)

B.Role-Based Access Control (RBAC)

C.Discretionary Access Control (DAC)

D.Attribute-Based Access Control (ABAC)

Explanation: Attribute-Based Access Control (ABAC) evaluates multiple attributes to make authorization decisions, including user attributes (department, clearance), resource attributes (classification, owner), and environmental attributes (time, location, threat level). ABAC provides fine-grained, dynamic access control that can adapt to changing conditions. This is more flexible than RBAC which only considers roles, MAC which uses fixed labels, or DAC which relies on ownership.

4What is the principle of least privilege in access control?

A.Granting all users administrator access to prevent help desk calls

B.Providing users with the minimum access necessary to perform their job functions

C.Requiring multi-factor authentication for all system access

D.Logging all user activities for compliance purposes

Explanation: The principle of least privilege states that users and processes should only be granted the minimum access rights necessary to perform their authorized tasks. This limits the potential damage from compromised accounts, reduces the attack surface, and prevents accidental or intentional misuse of privileges. Regular access reviews and just-in-time privilege elevation are common implementations of this principle.

5Which password policy setting is MOST effective at preventing brute force attacks?

A.Requiring passwords to contain special characters

B.Enforcing account lockout after a specified number of failed attempts

C.Mandating password changes every 30 days

D.Requiring minimum password length of 8 characters

Explanation: Account lockout policies that temporarily or permanently disable accounts after a specified number of failed login attempts are the most effective defense against brute force attacks. While password complexity (special characters, length) and rotation requirements help, they do not directly prevent attackers from trying unlimited password combinations. Account lockout stops automated attacks by limiting attempts.

6A company wants to ensure that users cannot share their passwords with colleagues. Which technical control BEST addresses this requirement?

A.Implementing Multi-Factor Authentication (MFA)

B.Requiring password complexity of 12+ characters

C.Prohibiting password reuse across systems

D.Implementing biometric authentication

Explanation: Multi-Factor Authentication (MFA) is the most effective control to prevent password sharing because even if a user shares their password, an attacker would still need the second factor (something the user has or is) to authenticate. Password complexity and reuse policies do not prevent sharing. Biometric authentication alone also works but MFA specifically addresses the password sharing problem while maintaining usability.

7In a Mandatory Access Control (MAC) system, which entities are responsible for determining access to classified information?

A.The resource owners

B.The system administrator based on security policies

C.The end users based on their job requirements

D.The security kernel based on labels and clearances

Explanation: In Mandatory Access Control (MAC) systems, access decisions are made by the operating system's security kernel based on security labels assigned to subjects (users/processes) and objects (resources). The kernel enforces access rules automatically without user discretion. This is commonly used in military and government environments where data classification (Top Secret, Secret, Confidential) and user clearances determine access.

8An organization is implementing a privileged access management solution. Which approach aligns with the principle of just-in-time (JIT) access?

A.Granting administrators permanent 24/7 privileged access

B.Providing elevated privileges only when needed and for a limited time

C.Requiring annual recertification of all privileged accounts

D.Implementing separate accounts for privileged and standard activities

Explanation: Just-in-Time (JIT) access provides elevated privileges only when needed and automatically revokes them after a specified time period. This reduces the attack surface by minimizing the window of opportunity for attackers and limiting standing privileges. While annual recertification and separate accounts are good practices, they do not implement the time-limited, on-demand aspect of JIT access.

9A security analyst discovers that several employees have written passwords on sticky notes attached to their monitors. What is the MOST effective solution to address this behavior?

A.Implementing technical controls such as password managers and SSO

B.Increasing the password complexity requirements

C.Enforcing more frequent password changes

D.Installing surveillance cameras to monitor workstations

Explanation: Password managers and Single Sign-On (SSO) solutions address the root cause of password writing behavior by reducing the cognitive burden of remembering multiple complex passwords. Users only need to remember one master password or use biometric authentication. Increasing complexity or rotation frequency often worsens the problem. Surveillance is not an effective security control for this issue.

10Which of the following is a characteristic of Discretionary Access Control (DAC)?

A.Access decisions are enforced by the operating system kernel

B.Resource owners can determine who has access to their resources

C.Access is determined by security labels and clearances

D.Permissions are based on predefined organizational roles

Explanation: In Discretionary Access Control (DAC), resource owners (creators or designated owners) have discretion to determine who can access their resources and what permissions they have. This is common in consumer operating systems where file owners can set permissions. MAC uses kernel enforcement and labels, RBAC uses roles - neither allows owner discretion.
