Here are 8 multiple-choice questions designed to mirror the difficulty and style of the ISC2 SSCP exam, covering a range of domains from the official Common Body of Knowledge (CBK).
SSCP Practice Questions See also CISA Sample Questions With Full Explanations for a complementary perspective.
These questions test your applied knowledge of security concepts, risk management, and operational controls, just like the real exam. Choose the best answer for each scenario.
Q1. A security analyst is reviewing firewall logs and notices a high volume of outbound connections from a single internal workstation to a foreign IP address on port 443. The workstation is not part of any expected business process that communicates with this address. Which type of malware behavior is MOST likely indicated?
A. Ransomware encryption
B. Command and control (C2) beaconing
C. A worm exploiting a local vulnerability
D. A logic bomb triggered by a specific date
Answer: B
Explanation: Command and control (C2) beaconing is characterized by infected hosts periodically reaching out to a remote server to receive instructions or exfiltrate data. Ransomware typically communicates once for encryption keys, worms spread automatically without a central C2, and logic bombs trigger on a local condition, not continuous outbound traffic.
Q2. An organization is implementing a new access control system. Management requires that each user's access rights be based on their current role within the company, such as "HR Manager" or "Network Engineer." Changes to job duties must automatically update user permissions. Which access control model BEST fits this requirement?
A. Discretionary Access Control (DAC)
B. Mandatory Access Control (MAC)
C. Role-Based Access Control (RBAC)
D. Attribute-Based Access Control (ABAC)
Answer: C
Explanation: Role-Based Access Control (RBAC) assigns permissions based on a user's role, and changes to the role automatically propagate to the user's effective permissions. DAC allows the data owner to set permissions, MAC uses security labels, and ABAC uses a wider range of attributes (time, location, etc.), but RBAC is the most direct fit for the role-centric requirement.
Q3. An incident responder is analyzing a compromised system. The attacker gained access by exploiting a vulnerability in an outdated web browser plugin. The responder needs to determine the exact sequence of events, including the initial exploit, privilege escalation, and lateral movement. Which forensic process is being performed?
A. Chain of custody
B. Data acquisition
C. Timeline analysis
D. Order of volatility
Answer: C
Explanation: Timeline analysis (or event reconstruction) involves correlating timestamps from various logs and files to build a chronological sequence of the attack. Chain of custody documents the handling of evidence, data acquisition is the copying of evidence, and order of volatility dictates the sequence in which evidence should be collected (e.g., RAM before disk).
Q4. A company's web application allows users to upload profile pictures. An attacker uploads a file containing malicious server-side code, which is then executed when the file is accessed via the web server. This results in the attacker gaining remote control of the server. Which of the following controls would MOST effectively prevent this attack?
A. Input validation on the client side using JavaScript For more on this topic, see our guide on CKS Sample Questions With Full Explanations.
B. A Web Application Firewall (WAF) that detects SQL injection
C. Implementing a whitelist of allowed file extensions and content types
D. Encrypting all traffic between the user and the server using TLS
Answer: C
Explanation: The attack is a file upload vulnerability, a form of malicious code execution. A whitelist that only allows specific file types (like .jpg or .png) and validates the file's actual content (magic bytes) prevents the upload of executable files. Client-side validation is easily bypassed, a WAF for SQLi doesn't address this vector, and TLS only protects data in transit, not the uploaded file's execution.
Q5. A system administrator is configuring a new server and needs to ensure that a specific process runs with the lowest possible privileges necessary to perform its function. The process only needs to read a specific configuration file and write to a single log file. What is the administrator implementing?
A. Separation of duties
B. Defense in depth
C. Least privilege
D. Job rotation
Answer: C
Explanation: The principle of least privilege dictates that a user or process should be granted only the minimum permissions required to complete its task. The administrator is limiting the process to read one file and write to another, which is a direct application of this principle. Separation of duties requires multiple people for critical tasks, defense in depth uses multiple layers of security, and job rotation is a personnel control.
Q6. A security team is planning to test the effectiveness of their network intrusion detection system (IDS). They want to generate realistic attack traffic without causing any actual damage to their production systems. Which of the following techniques is BEST suited for this purpose?
A. Vulnerability scanning
B. Penetration testing
C. Red team exercise
D. Protocol fuzzing
Answer: C
Explanation: A red team exercise is a goal-based, adversarial simulation that uses real-world attack techniques and tools, but operates within defined rules of engagement to avoid damage. While penetration testing is similar, a red team exercise is more holistic and focuses on testing the entire detection and response capability, which aligns with testing the IDS. Vulnerability scanning is passive and doesn't generate attack traffic, and protocol fuzzing is a specific testing technique for input handling, not a full attack simulation.
Q7. An organization is required by a new regulation to encrypt all sensitive data at rest. They need to encrypt files stored on a network file server without requiring users to change their workflow. The encryption keys must be managed centrally. Which of the following solutions is MOST appropriate?
A. Full Disk Encryption (FDE) on each user's workstation
B. File-level encryption using a third-party application
C. Database encryption for the file server's metadata
D. Transparent encryption at the file system or storage layer Readers also benefit from Cisco CyberOps Associate Sample Questions With Full Explanations.
Answer: D
Explanation: Transparent encryption (e.g., at the file system or SAN level) encrypts data automatically as it is written to disk and decrypts it as it is read, without user intervention or changes to workflow. Central key management is a feature of enterprise-grade storage/file system encryption solutions. FDE on workstations doesn't protect data on the central server, and database encryption only protects structured data, not files.
Q8. A security administrator is configuring a new firewall rule. The requirement is to allow outbound HTTPS (port 443) traffic from the internal network to any external web server. However, the administrator must also ensure that return traffic from the external server is allowed back into the internal network. Which type of firewall implementation automatically handles this return traffic?
A. Stateless packet filtering
B. Stateful packet filtering
C. Application-level gateway
D. Circuit-level proxy
Answer: B
Explanation: A stateful firewall tracks the state of active connections (e.g., the outbound TCP handshake) and uses a state table to automatically allow the associated return traffic. Stateless filtering would require separate, manual rules for inbound traffic, which is less secure and more complex. Application gateways and circuit-level proxies work at higher layers and are not the primary mechanism for handling the state of a basic TCP connection.
Q9. An organization's business continuity plan (BCP) identifies a Recovery Time Objective (RTO) of 4 hours and a Recovery Point Objective (RPO) of 15 minutes for its primary customer database. Which of the following backup and recovery strategies BEST meets these requirements?
A. Daily full backups to tape, restored to a cold site
B. Hourly incremental backups to a local disk, restored to a warm site
C. Continuous data replication to a hot site with automated failover
D. Weekly differential backups to a cloud storage service
Answer: C
Explanation: An RPO of 15 minutes means the organization can only afford to lose 15 minutes of data, which requires near-continuous data replication (e.g., synchronous or near-synchronous). An RTO of 4 hours requires a hot site that can be activated quickly with automated failover. Daily backups (A, D) have too high an RPO, and hourly incremental backups (B) have an RPO of up to one hour, which exceeds the 15-minute requirement.
Q10. A user receives a phone call from someone claiming to be from the IT help desk. The caller states they are performing a security update and need the user's password to "verify" their account. The user provides the password. What type of social engineering attack has occurred?
A. Phishing
B. Vishing
C. Smishing
D. Pretexting
Answer: D
Explanation: Pretexting is a form of social engineering where an attacker creates a fabricated scenario (the "pretext") to steal information. The caller used a false reason (security update) to get the password. While vishing is a voice-based attack, the specific technique of using a false identity and reason to obtain information is more accurately classified as pretexting. Phishing is typically email-based, and smishing is SMS-based.
