cyber analyst Interview Questions and Answers

1. What is a cyber attack?

   • Answer: A cyberattack is any type of offensive attempt to gain unauthorized access to a computer system or network. This can range from simple denial-of-service attacks to sophisticated attempts to steal data, install malware, or disrupt operations.

2. Explain the difference between a virus and a worm.

   • Answer: A virus needs a host program to spread, attaching itself to existing files. A worm is a self-replicating program that spreads independently across networks, often exploiting vulnerabilities.

3. What is phishing?

   • Answer: Phishing is a cyberattack where malicious actors attempt to trick individuals into revealing sensitive information, such as usernames, passwords, and credit card details, by disguising themselves as a trustworthy entity in electronic communication.

4. What is a firewall?

   • Answer: A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between a trusted internal network and an untrusted external network, such as the internet.

5. Explain the concept of intrusion detection systems (IDS).

   • Answer: An intrusion detection system (IDS) is a device or software application that monitors a network or system for malicious activity or policy violations. It analyzes network traffic and system logs for suspicious patterns and alerts administrators to potential security threats.

6. What is the difference between IDS and IPS?

   • Answer: An IDS (Intrusion Detection System) only detects intrusions, while an IPS (Intrusion Prevention System) detects and actively prevents intrusions by blocking malicious traffic or taking other preventative actions.

7. What are common types of malware?

   • Answer: Common types of malware include viruses, worms, Trojans, ransomware, spyware, adware, and rootkits.

8. What is SQL injection?

   • Answer: SQL injection is a code injection technique used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution (e.g., to dump the database contents to the attacker).

9. What is cross-site scripting (XSS)?

   • Answer: Cross-site scripting (XSS) is a type of computer security vulnerability typically found in web applications. XSS enables attackers to inject client-side scripts into web pages viewed by other users.

10. Describe the role of a SIEM system.

    • Answer: A Security Information and Event Management (SIEM) system collects and analyzes security data from various sources, including network devices, servers, and applications, to detect and respond to security threats. It provides a centralized view of security events and helps organizations manage and mitigate risks.

11. What is vulnerability scanning?

    • Answer: Vulnerability scanning is the automated process of identifying security vulnerabilities in computer systems and networks. It involves using specialized software to scan systems for known weaknesses and configuration issues that could be exploited by attackers.

12. What is penetration testing?

    • Answer: Penetration testing, also known as ethical hacking, is a simulated cyberattack against a computer system, network, or application to identify security vulnerabilities. It involves attempting to exploit weaknesses to assess the overall security posture.

13. Explain the concept of risk assessment.

    • Answer: Risk assessment is the process of identifying and analyzing potential threats and vulnerabilities to determine the likelihood and potential impact of security incidents. It involves evaluating the risks to an organization's assets and developing mitigation strategies.

14. What is a honeypot?

    • Answer: A honeypot is a decoy system designed to attract and trap attackers. It's used to gather intelligence about attackers, analyze their techniques, and slow down or prevent attacks on critical systems.

15. What is incident response?

    • Answer: Incident response is the coordinated actions taken to identify, analyze, contain, and recover from a security incident. It involves a structured process to minimize damage and restore normal operations.

16. What are some common network protocols?

    • Answer: Common network protocols include TCP/IP, HTTP, HTTPS, FTP, SMTP, DNS, and DHCP.

17. What is a denial-of-service (DoS) attack?

    • Answer: A denial-of-service (DoS) attack is a cyber-attack where the perpetrator seeks to make a machine or network resource unavailable to its intended users. This is achieved by temporarily or indefinitely disrupting services of a host connected to the Internet.

18. What is a distributed denial-of-service (DDoS) attack?

    • Answer: A distributed denial-of-service (DDoS) attack is a denial-of-service attack where multiple compromised systems (often bots) are used to flood the target with traffic, making it much harder to defend against.

19. What is a man-in-the-middle (MITM) attack?

    • Answer: A man-in-the-middle (MITM) attack is an attack where the attacker secretly relays and possibly alters the communication between two parties who believe they are directly communicating with each other.

20. Explain the importance of data loss prevention (DLP).

    • Answer: Data loss prevention (DLP) is a strategy for preventing sensitive data from leaving the organization's control. This is crucial for protecting against data breaches and maintaining regulatory compliance.

21. What is blockchain technology and its relevance to cybersecurity?

    • Answer: Blockchain is a distributed, immutable ledger that can enhance cybersecurity by providing tamper-proof records of transactions and events. This can be useful for tracking data provenance and improving audit trails.
