1. Which protocol is used to securely access websites over the internet?
A. HTTP
B. HTTPS
C. FTP
D. SMTP
Answer: b) HTTPS
Rationale: HTTPS (HyperText Transfer Protocol Secure) uses encryption (SSL/TLS) to secure
communications between the browser and the server.
2. What is an example of a brute-force attack?
A. Trying all possible combinations to crack a password
B. Installing a keylogger on a victim’s machine
C. Sending multiple phishing emails to gather information
D. Intercepting communication between two parties
Answer: a) Trying all possible combinations to crack a password
Rationale: A brute-force attack involves systematically trying all possible password
combinations until the correct one is found.
3. What is "data exfiltration"?
,A. Encrypting data to protect it from unauthorized access
B. The process of transferring data out of a system without authorization
C. Storing data in a secure cloud service
D. The process of backing up data to prevent loss
Answer: b) The process of transferring data out of a system without authorization
Rationale: Data exfiltration refers to the unauthorized transfer of data from a system to an
external location, often for malicious purposes.
4. What is a "backdoor" in cybersecurity?
A. A type of malware that spreads rapidly
B. A secret entry point into a system that bypasses normal authentication
C. A security patch released by vendors
D. A type of firewall used to monitor network traffic
Answer: b) A secret entry point into a system that bypasses normal authentication
Rationale: A backdoor is a hidden method of accessing a system without going through its usual
authentication processes.
5. What does the term "encryption" mean in cybersecurity?
A. Converting readable data into an unreadable format to protect it from unauthorized access
B. The process of creating backup copies of data
C. The process of deleting sensitive data securely
, D. The process of scanning files for malware
Answer: a) Converting readable data into an unreadable format to protect it from unauthorized
access
Rationale: Encryption transforms data into an unreadable format using an algorithm and a key,
ensuring that unauthorized individuals cannot access or understand the data.
6. What type of attack involves overwhelming a system with excessive traffic to disrupt its
operations?
A. Phishing
B. Man-in-the-middle
C. DDoS (Distributed Denial of Service)
D. SQL injection
Answer: c) DDoS (Distributed Denial of Service)
Rationale: DDoS attacks use multiple systems to flood a target with traffic, rendering the system
unavailable.
7. What is the term "SQL injection" used to describe?
A. An attack where malicious SQL queries are inserted into a website’s database
B. An attack where a system is flooded with excessive SQL queries
C. An attempt to decrypt SQL data
D. A method of storing SQL passwords securely
A. HTTP
B. HTTPS
C. FTP
D. SMTP
Answer: b) HTTPS
Rationale: HTTPS (HyperText Transfer Protocol Secure) uses encryption (SSL/TLS) to secure
communications between the browser and the server.
