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 Security Concepts and Practices domain (16% of the exam).

Sample Question 1 — Security Concepts and Practices

Your company has recently deployed a new web application on a Windows Server 2019 platform. As a security practitioner, you are tasked with ensuring that the server is hardened against unauthorized access and potential vulnerabilities. Which of the following actions should you take to effectively secure the server?

  1. A. Disable unnecessary services and remove default accounts. (Correct answer)
  2. B. Install a third-party antivirus solution without updating it.
  3. C. Enable guest access to allow easier troubleshooting.
  4. D. Open all firewall ports to ensure application functionality.

Correct answer: A

Explanation: Disabling unnecessary services and removing default accounts helps reduce the attack surface by limiting the number of potential entry points for attackers. Installing antivirus is important, but it must be updated to be effective, making option B incomplete. Enabling guest access (option C) and opening all firewall ports (option D) would increase the risk of unauthorized access and are not recommended practices.

Sample Question 2 — Security Concepts and Practices

During a routine security audit, you discover that one of the Linux servers in your network is generating an unusually high amount of outbound traffic. After further investigation, you suspect that the server might have been compromised. Which of the following steps should you take first to address the situation?

  1. A. Immediately disconnect the server from the network to prevent further data exfiltration. (Correct answer)
  2. B. Reboot the server to clear any potential malicious processes.
  3. C. Run a full system antivirus scan while the server remains online.
  4. D. Update all software and patches on the server before further investigation.

Correct answer: A

Explanation: Disconnecting the server from the network is the most immediate action to prevent further data exfiltration and contain the potential breach. Rebooting the server (option B) could destroy volatile evidence needed for a forensic investigation. Running an antivirus scan (option C) is useful but should be done after containment. Updating software (option D) is important but not the first step in an active incident response scenario.

Sample Question 3 — Security Concepts and Practices

You are responsible for configuring a new firewall for your company's network. The firewall needs to allow inbound HTTPS traffic to a web server located in the DMZ while denying all other inbound traffic. Which of the following rule sets would accomplish this task?

  1. A. Allow inbound TCP traffic on port 443 to the web server; deny all other inbound traffic. (Correct answer)
  2. B. Allow inbound TCP traffic on port 80 to the web server; allow all other inbound traffic.
  3. C. Deny all inbound traffic; allow inbound TCP traffic on port 443 to the web server.
  4. D. Allow inbound UDP traffic on port 443 to the web server; deny all other inbound traffic.

Correct answer: A

Explanation: Option A is correct because it allows inbound HTTPS (TCP port 443) traffic to the web server while denying all other inbound traffic, which is the goal. Option B is incorrect because it allows HTTP (port 80) traffic and does not deny other traffic. Option C is incorrect as it denies all inbound traffic first, which would prevent any traffic from reaching the server. Option D is incorrect because HTTPS uses TCP, not UDP.

Sample Question 4 — Security Concepts and Practices

A security practitioner notices an unusual spike in outbound traffic from a server that should not be transmitting large amounts of data. Which tool would be most appropriate to investigate the cause of this anomaly?

  1. A. Network Intrusion Detection System (NIDS)
  2. B. Security Information and Event Management (SIEM) (Correct answer)
  3. C. Vulnerability Scanner
  4. D. Data Loss Prevention (DLP) system

Correct answer: B

Explanation: Option B is correct because a SIEM can correlate logs and provide insights into the source and nature of the traffic anomaly. Option A, a NIDS, is more suited for detecting intrusions rather than analyzing outbound traffic. Option C, a vulnerability scanner, is used for identifying vulnerabilities, not traffic analysis. Option D, a DLP system, is intended to prevent data exfiltration but may not provide detailed analysis of traffic spikes.

Sample Question 5 — Security Concepts and Practices

You are tasked with securing a Linux server that will host sensitive data. Which of the following actions should you prioritize to enhance the security of the server?

  1. A. Disable unused services and daemons. (Correct answer)
  2. B. Set up a guest account for temporary users.
  3. C. Enable SSH root login for administrative convenience.
  4. D. Install a GUI for easier management.

Correct answer: A

Explanation: Option A is correct because disabling unused services reduces the attack surface of the server. Option B is incorrect because guest accounts can pose a security risk. Option C is incorrect as enabling SSH root login is a security risk; it is better to use sudo for administrative tasks. Option D is incorrect because installing a GUI can introduce additional vulnerabilities and is unnecessary for server management.

Sample Question 6 — Security Concepts and Practices

During a security audit, you discover that several Windows servers have not been patched for critical vulnerabilities. What is the best course of action to mitigate the risks associated with these unpatched systems?

  1. A. Immediately disconnect the servers from the network to prevent exploitation.
  2. B. Apply the latest patches and updates to the servers as soon as possible. (Correct answer)
  3. C. Monitor the servers closely for any signs of compromise.
  4. D. Implement a firewall rule to block all traffic to and from the servers.

Correct answer: B

Explanation: Option B is correct as applying the latest patches and updates is the most effective way to mitigate risks from known vulnerabilities. Option A is impractical as it disrupts service availability. Option C is reactive and does not address the vulnerabilities. Option D is overly restrictive and may not be feasible, especially if the servers provide critical services.
