Entry Level Cyber Security Analyst Interview Questions and Answers
1. What is cybersecurity, and why is it important?
Cybersecurity refers to the practice of protecting systems, networks, and programs from digital attacks. It is crucial because it ensures the confidentiality, integrity, and availability of information.
2. What is the difference between a vulnerability and a threat?
A vulnerability is a weakness in a system that can be exploited, while a threat is a potential for a security breach.
3. Explain the CIA Triad.
The CIA Triad consists of three components: Confidentiality, Integrity, and Availability, which are fundamental principles in cybersecurity.
4. What is a firewall?
A firewall is a network security device that monitors and filters incoming and outgoing network traffic based on security rules.
5. What are the different types of firewalls?
There are several types of firewalls including packet-filtering firewalls, stateful inspection firewalls, proxy firewalls, and next-generation firewalls (NGFW).
6. What is an intrusion detection system (IDS)?
An IDS is a device or software application that monitors a network or systems for malicious activity or policy violations.
7. What is the difference between IDS and IPS?
An IDS detects and alerts on security breaches, while an IPS (Intrusion Prevention System) detects and takes action to prevent a security breach.
8. What is encryption?
Encryption is the process of converting data into a coded format to prevent unauthorized access.
9. What is the difference between symmetric and asymmetric encryption?
Symmetric encryption uses the same key for both encryption and decryption, while asymmetric encryption uses a pair of keys – one public and one private.
10. What are network protocols?
Network protocols are rules that govern data communication between devices over a network, such as HTTP, FTP, and TCP/IP.
11. Explain VPN and its uses.
A VPN (Virtual Private Network) extends a private network across a public network, allowing users to send and receive data as if their devices were directly connected to the private network.
12. What is a brute force attack?
A brute force attack involves trying all possible combinations of passwords or encryption keys until the correct one is found.
13. What are some common types of malware?
Common types of malware include viruses, worms, Trojan horses, ransomware, adware, and spyware.
14. What is phishing?
Phishing is a cyberattack where attackers pose as legitimate entities to trick individuals into providing sensitive information.
15. What is social engineering?
Social engineering is the manipulation of individuals to divulge confidential information, often through deception.
16. What are patches and why are they important?
Patches are updates to software that fix vulnerabilities and improve security, thus preventing cyber attacks.
17. Explain the principle of least privilege.
The principle of least privilege restricts user permissions to the minimum necessary for their tasks, reducing the risk of unauthorized access.
18. What is two-factor authentication (2FA)?
2FA is a security process where users provide two different authentication factors to verify their identity.
19. What is a security policy?
A security policy is a set of rules and practices that regulate how an organization protects its information assets.
20. What is a honeypot?
A honeypot is a decoy system set up to attract and analyze cyber attackers.
21. What are zero-day vulnerabilities?
Zero-day vulnerabilities are flaws in software that are unknown to the vendor and can be exploited by attackers.
22. What are botnets?
Botnets are networks of compromised computers controlled by an attacker to perform coordinated malicious activities.
23. Describe the concept of risk management in cybersecurity.
Risk management involves identifying, assessing, and mitigating risks to an organization’s information assets.
24. What is ransomware?
Ransomware is a type of malware that encrypts a victim’s data and demands payment to restore access.
25. What is the difference between black-hat and white-hat hackers?
Black-hat hackers engage in illegal hacking, while white-hat hackers use their skills for ethical purposes to strengthen security.
26. What is steganography and how is it used in cybersecurity?
Steganography is the practice of hiding information within other non-secret data, often used for covert communication.
27. Explain the difference between a virus and a worm.
A virus attaches itself to a legitimate program to spread, while a worm can self-replicate and spread independently.
28. What is DDoS?
DDoS (Distributed Denial of Service) is an attack where multiple compromised systems flood a target with traffic, overwhelming it.
29. What is the purpose of a security audit?
A security audit evaluates an organization’s security policies, measures, and readiness against potential threats.
30. What is penetration testing?
Penetration testing is a simulated cyber attack against a system to identify and address security weaknesses.
31. What is a security incident?
A security incident is an event that compromises the integrity, confidentiality, or availability of information assets.
32. What is the importance of data backups?
Data backups ensure that data can be recovered in case of loss or corruption, ensuring business continuity.
33. What is an access control list (ACL)?
An ACL is a list of permissions attached to an object that specifies which users or system processes can access it.
34. What are cookies and how do they relate to security?
Cookies are small pieces of data stored by a web browser that can be exploited for tracking and malicious purposes if not handled securely.
35. Explain the term “man-in-the-middle attack.”
A man-in-the-middle attack involves an attacker secretly intercepting and possibly altering the communication between two parties.
36. What is the function of antivirus software?
Antivirus software scans, detects, and removes malicious software from systems to prevent damage.
37. What is SQL Injection?
SQL Injection is a code injection technique that exploits vulnerabilities in an application’s software by including malicious SQL statements.
38. What is cross-site scripting (XSS)?
XSS is a security vulnerability that allows attackers to inject malicious scripts into web pages viewed by other users.
39. What is a digital certificate?
A digital certificate authenticates the identity of the certificate holder, using public key infrastructure (PKI).
40. What is the significance of GDPR?
GDPR (General Data Protection Regulation) is a regulation in EU law that protects the privacy and personal data of individuals.
41. What is a security patch?
A security patch is an update issued by software vendors to fix vulnerabilities and protect systems against attacks.
42. What is the difference between cybersecurity and information security?
Cybersecurity focuses on protecting systems and networks from digital attacks, while information security encompasses broader aspects, including data protection and access controls.
43. What is a sandbox in cybersecurity?
A sandbox is an isolated testing environment where software can be executed safely without affecting the system.
44. What is PKI?
PKI (Public Key Infrastructure) is a framework for creating, managing, and distributing digital certificates.
