Sample EXIN Cyber Security Foundation Practice Questions

Try these sample questions to test your EXIN Cyber Security Foundation exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which component of the CIA triad ensures that information is accessible only to authorized individuals, entities, or processes?
A.Confidentiality
B.Integrity
C.Availability
D.Non-repudiation
Explanation: Confidentiality prevents unauthorized disclosure of sensitive data by enforcing access controls, encryption, and classification policies. It guarantees that only authorized users can read or access the information.
2An organization implements SHA-256 hash checks to verify that downloaded software installation files have not been modified during transit. Which CIA triad principle is being protected?
A.Availability
B.Integrity
C.Confidentiality
D.Accountability
Explanation: Integrity ensures that data has not been modified, corrupted, or tampered with by unauthorized parties. Hash algorithms like SHA-256 produce fixed-length digests that change dramatically if even a single bit of the file is altered.
3A Distributed Denial of Service (DDoS) attack floods an e-commerce website with traffic, making it impossible for legitimate customers to complete orders. Which security objective is directly compromised?
A.Confidentiality
B.Integrity
C.Availability
D.Authenticity
Explanation: Availability ensures that authorized users have timely and reliable access to information and operational systems. DDoS attacks target availability by overwhelming network bandwidth or server resources.
4Which security property provides proof of the origin and integrity of a transaction such that the sender cannot falsely deny having sent the message?
A.Confidentiality
B.Non-repudiation
C.High availability
D.Authorization
Explanation: Non-repudiation ensures that a party to a contract or communication cannot deny the authenticity of their signature on a document or the sending of a message that they originated. Digital signatures utilizing asymmetric cryptography are commonly used to achieve non-repudiation.
5What type of malicious software encrypts a victim's files and demands financial payment in exchange for the decryption key?
A.Spyware
B.Ransomware
C.Adware
D.Rootkit
Explanation: Ransomware is a form of malware that encrypts files or locks users out of their operating system until a ransom is paid to the attacker. Common examples include WannaCry and LockBit.
6A malicious application installed on a user's workstation covertly records every keystroke, capturing sensitive passwords and credit card numbers. What category of malware is this?
A.Keylogger
B.Logic bomb
C.Trojan horse
D.Ransomware
Explanation: A keylogger (a type of spyware) records input typed on a keyboard to capture sensitive data such as credentials, financial details, and personal communications, sending this data to a remote attacker.
7What is the primary operational difference between a computer worm and a computer virus?
A.A worm encrypts files, whereas a virus deletes system log files.
B.A worm self-propagates across network connections without user interaction, while a virus requires a host file and human action to spread.
C.A virus operates only in kernel mode, while a worm operates strictly in user space.
D.A virus targets network hardware switches, while a worm targets web browsers.
Explanation: Worms are standalone malicious programs capable of self-replicating and spreading autonomously over networks without needing host files or user intervention. Viruses require insertion into host file executables and rely on user execution to spread.
8Which feature makes a rootkit particularly difficult for standard security tools and antivirus software to detect?
A.It alters physical disk drive sector sizes upon infection.
B.It subverts OS kernel function calls and hides processes, files, and registry entries at Ring 0 or hypervisor levels.
C.It requires user credentials to execute every 24 hours.
D.It encrypts network traffic using standard SSL certificates registered to legitimate vendors.
Explanation: Rootkits operate at deep privilege levels (such as Ring 0 kernel level or Ring -1 hypervisor level), hooking operating system APIs and kernel structures to intercept and filter system calls, effectively concealing their presence from standard security processes.
9A rogue software developer embeds code inside a company's payroll system that automatically deletes the entire employee database if the developer's user account is deactivated. What type of threat is this?
A.Logic bomb
B.Macro virus
C.Watering hole attack
D.Fileless malware
Explanation: A logic bomb is a piece of code intentionally inserted into a software system that remains dormant until specific criteria or conditions (such as date, time, or account deactivation) are met, at which point it triggers malicious payload execution.
10An attacker sends a highly targeted email to the Chief Financial Officer (CFO) of a company, posing as the CEO and requesting an urgent wire transfer to a fraudulent vendor account. What specialized social engineering attack is this?
A.Dumpster diving
B.Whaling
C.Shoulder surfing
D.Smishing
Explanation: Whaling is a specific type of spear phishing attack directed at high-profile executives (such as CEOs, CFOs, or senior managers) to trick them into transferring funds or revealing sensitive corporate information.

EXIN Cyber Security Foundation Study Tips from Top Performers

1Memorize the CIA triad definitions and be able to identify which property is compromised in specific attack scenarios.
2Understand the difference between symmetric encryption (fast, shared secret key) and asymmetric encryption (public/private key pair used for key exchange and digital signatures).
3Differentiate between preventive, detective, corrective, and compensating security controls across physical, technical, and administrative categories.
4Learn the core phases of the Incident Response Lifecycle (Preparation, Identification, Containment, Eradication, Recovery, Lessons Learned).
5Understand the operational distinctions between a stateless packet filter, stateful inspection firewall, and Next-Generation Firewall (NGFW).
6Be familiar with key metrics in Business Continuity and Disaster Recovery: Recovery Time Objective (RTO) and Recovery Point Objective (RPO).
7Study multi-factor authentication factors: Something you know (password/PIN), Something you have (smartcard/token), and Something you are (biometrics).
