Free SSCP Access Controls Practice Questions with Answers

Each question below includes 4 answer options, the correct answer, and a detailed explanation. These are real questions from the FlashGenius SSCP question bank for the Access Controls domain (15% of the exam).

Sample Question 1 — Access Controls

You are a security practitioner responsible for managing access controls in a multi-tenant cloud environment. Recently, a user reported that they are unable to access a specific application they previously had access to. Upon investigation, you find that the user's role was recently changed. Which of the following steps should you take to resolve this issue while adhering to the principle of least privilege?

  1. A. Revert the user's role to their previous role to restore access.
  2. B. Grant the user full administrative privileges temporarily to troubleshoot the issue.
  3. C. Review the access permissions of the new role and modify them to include access to the necessary application. (Correct answer)
  4. D. Add the user to a group that has access to the application, ensuring they can perform their tasks.

Correct answer: C

Explanation: The correct answer is C. Reviewing and modifying the access permissions of the new role ensures that the user has the necessary access while maintaining the principle of least privilege. Option A reverts the user back to a potentially outdated role, which might not align with current security policies. Option B violates the principle of least privilege by granting excessive permissions. Option D might grant more access than necessary and could lead to privilege creep.

Sample Question 2 — Access Controls

You are tasked with configuring a new firewall for a corporate network. During a security audit, it was found that several users have unnecessary access to sensitive resources due to overly permissive firewall rules. Which of the following actions would best mitigate this issue while maintaining necessary access for legitimate users?

  1. A. Implement a deny-all policy and manually add rules to allow necessary traffic. (Correct answer)
  2. B. Create a detailed log of all current traffic and adjust the rules based on the log.
  3. C. Remove all existing rules and start from scratch to ensure only necessary access is granted.
  4. D. Increase the logging level to capture more detailed traffic information for ongoing analysis.

Correct answer: A

Explanation: The correct answer is A. Implementing a deny-all policy and then adding rules to allow necessary traffic ensures that only authorized traffic is permitted, aligning with the principle of least privilege. Option B, while useful for analysis, does not directly address the issue of overly permissive rules. Option C is risky and could disrupt legitimate access, leading to potential downtime. Option D focuses on monitoring rather than actively addressing the permissive access issue.

Sample Question 3 — Access Controls

You are a security administrator responsible for managing access controls on a Linux server hosting sensitive data. Recently, there have been multiple failed login attempts from an unknown IP address. Which of the following actions should you take first to enhance security?

  1. A. Disable SSH access for all users except the root user.
  2. B. Implement IP whitelisting to allow only known IP addresses to access the server. (Correct answer)
  3. C. Increase the complexity requirements for user passwords.
  4. D. Configure the server to use a different port for SSH connections.

Correct answer: B

Explanation: Implementing IP whitelisting is an effective way to limit access to known and trusted IP addresses, thereby reducing the risk of unauthorized access. Disabling SSH for all users except root is not recommended as it violates the principle of least privilege. Increasing password complexity and changing the SSH port are good practices but do not directly address the immediate threat of unauthorized access from unknown IPs.

Sample Question 4 — Access Controls

As part of a security audit, you are tasked with reviewing firewall rules on a Windows server. You notice a rule allowing inbound traffic on port 3389 from any IP address. What is the best course of action to secure RDP access to the server?

  1. A. Disable the rule entirely to prevent all RDP access.
  2. B. Restrict the rule to allow only specific IP addresses that require RDP access. (Correct answer)
  3. C. Change the default RDP port to a non-standard port.
  4. D. Enable network-level authentication for RDP connections.

Correct answer: B

Explanation: Restricting the rule to allow only specific IP addresses is an effective way to secure RDP access by limiting it to known and trusted locations. Disabling the rule may disrupt legitimate access needs. Changing the RDP port and enabling network-level authentication are additional security measures but do not directly address the risk posed by allowing access from any IP address.

Sample Question 5 — Access Controls

During a routine security check, you find that a critical business application on a Linux server is running with root privileges. What is the most appropriate action to mitigate potential security risks?

  1. A. Reconfigure the application to run under a dedicated service account with limited privileges. (Correct answer)
  2. B. Implement a host-based intrusion detection system (HIDS) to monitor the application.
  3. C. Use SELinux to enforce strict access controls on the application.
  4. D. Enable logging to track all actions performed by the application.

Correct answer: A

Explanation: Reconfiguring the application to run under a dedicated service account with limited privileges aligns with the principle of least privilege, reducing the potential impact of a security breach. While using SELinux, HIDS, and logging are beneficial security practices, they do not address the fundamental issue of the application running with excessive privileges.

Sample Question 6 — Access Controls

A new policy requires that all network devices authenticate using RADIUS before granting access. During implementation, users report authentication failures. Which of the following is the most likely cause?

  1. A. The RADIUS server is not configured to accept requests from the network devices.
  2. B. The network devices are using outdated firmware that does not support RADIUS.
  3. C. The users are entering incorrect credentials.
  4. D. The network devices are configured with an incorrect shared secret for RADIUS authentication. (Correct answer)

Correct answer: D

Explanation: An incorrect shared secret between the network devices and the RADIUS server is a common cause of authentication failures, as it prevents the devices from properly communicating with the RADIUS server. While other options could potentially cause issues, the shared secret mismatch is the most directly related to the described authentication problem.

How to Study SSCP Access Controls

Combine these SSCP Access Controls practice questions with the official ISC2 study guide. Since October 2025 the SSCP uses adaptive CAT testing — one pass, no reviewing answers — so practice scenario-based judgment under timed conditions rather than memorizing definitions.
