Cyber Security Interview Questions

Here are some common cybersecurity interview questions along with their answers:

1. What is cryptography?

Answer: Cryptography is the practice of securing information by transforming it into an unreadable format (ciphertext) using algorithms and keys. It ensures confidentiality, integrity, and authentication of data.

2. What is the difference between symmetric and asymmetric encryption?

Answer:

• Symmetric Encryption: Uses a single key for both encryption and decryption. It’s faster but requires secure key distribution.
• Asymmetric Encryption: Uses a pair of keys (public and private). The public key encrypts data, and the private key decrypts it. It’s slower but eliminates the key distribution problem and provides digital signatures.

3. What is the difference between an IDS and an IPS?

Answer:

• IDS (Intrusion Detection System): Monitors network traffic for signs of suspicious or unauthorized activity and generates alerts or logs when detected.
• IPS (Intrusion Prevention System): Not only detects threats but also takes automated actions to block or prevent them based on predefined rules.

4. Explain the CIA triad.

Answer: The CIA triad stands for Confidentiality, Integrity, and Availability:

• Confidentiality: Ensures that data is only accessible to authorized users.
• Integrity: Guarantees the accuracy and trustworthiness of data, preventing unauthorized changes.
• Availability: Ensures that systems and data are accessible when needed, preventing downtime.

5. How is encryption different from hashing?

Answer:

• Encryption: Converts data into an unreadable format (ciphertext) that can be reversed with a decryption key. Used for confidentiality.
• Hashing: Converts data into a fixed-size, irreversible hash value. Used for data integrity and password storage.

6. What is a firewall and why is it used?

Answer: A firewall is a network security device or software that filters incoming and outgoing traffic based on predefined rules. It is used to protect a network or system from unauthorized access, malicious activity, and cyber threats.

7. What is the difference between a vulnerability assessment and a penetration test?

Answer:

• Vulnerability Assessment: Identifies and assesses vulnerabilities in a system or network to provide a comprehensive view of potential weaknesses.
• Penetration Test (Pen Test): Simulates real-world attacks to exploit vulnerabilities, demonstrating the impact and providing recommendations for mitigation.

8. What is a three-way handshake?

Answer: A three-way handshake is a process used in establishing a TCP/IP connection between two devices. It involves three steps: SYN (synchronize), SYN-ACK (acknowledge), and ACK (acknowledge again) to establish a connection and ensure proper communication.

9. What are the response codes that can be received from a web application?

Answer: Web applications often return HTTP status codes as responses. Common codes include:

• 200 (OK): Successful request.
• 404 (Not Found): Resource not found.
• 500 (Internal Server Error): Server-side error.
• 302 (Found): Temporary redirect.

10. What is traceroute? Why is it used?

Answer: Traceroute is a network diagnostic tool that maps the route data packets take between a source and destination. It’s used to identify network delays, packet loss, and routing issues by showing the sequence of hops (intermediate routers) taken by the packets.

These questions and answers serve as a foundation for discussing cybersecurity concepts during interviews. Be prepared to provide detailed explanations and examples to demonstrate your understanding of these topics.
