Here Top Cyber Security Interview Questions
What is Cybersecurity?
Answer: Cybersecurity refers to the practice of protecting systems, networks, and programs from digital attacks. These attacks aim to access, change, or destroy sensitive information, extort money, or interrupt normal business processes.
What are the different types of cybersecurity?
Answer: The main types include network security, information security, application security, operational security, and disaster recovery.
What is a firewall?
Answer: A firewall is a network security device that monitors and filters incoming and outgoing network traffic based on an organization’s previously established security policies.
Explain the difference between IDS and IPS.
Answer: Intrusion Detection Systems (IDS) detect and alert about potential security breaches, while Intrusion Prevention Systems (IPS) not only detect but also take action to prevent the threat.
What is a VPN?
Answer: A Virtual Private Network (VPN) is a service that encrypts your internet traffic and protects your online identity by creating a secure connection to another network over the internet.
What is multi-factor authentication?
Answer: Multi-factor authentication (MFA) is a security system that requires more than one method of authentication to verify the user’s identity for a login or other transaction.
What is phishing?
Answer: Phishing is a type of social engineering attack where attackers deceive users into divulging confidential information by pretending to be trustworthy entities.
What is a Man-in-the-Middle (MITM) attack?
Answer: An MITM attack occurs when an attacker intercepts communication between two parties to eavesdrop or alter the communication.
What is SQL injection?
Answer: SQL injection is a code injection technique that might destroy your database. It is one of the most common web hacking techniques.
What is a Zero-Day exploit?
Answer: A Zero-Day exploit refers to a cyberattack that occurs on the same day a weakness is discovered in software, before the developer has a chance to fix it.
What is the difference between symmetric and asymmetric encryption?
Answer: Symmetric encryption uses the same key for both encryption and decryption, while asymmetric encryption uses a public key for encryption and a private key for decryption.
What are the main types of malware?
Answer: The main types of malware include viruses, worms, Trojans, ransomware, spyware, adware, and rootkits.
What is ransomware?
Answer: Ransomware is a type of malicious software designed to block access to a computer system until a sum of money is paid.
What is social engineering?
Answer: Social engineering is a technique used by attackers to manipulate individuals into divulging confidential information.
What is the difference between black hat, white hat, and gray hat hackers?
Answer: Black hat hackers exploit vulnerabilities for malicious reasons, white hat hackers identify and fix vulnerabilities legally, and gray hat hackers fall somewhere in between.
What is a brute force attack?
Answer: A brute force attack involves trying multiple combinations of passwords or keys until the correct one is found.
What is a DDoS attack?
Answer: A Distributed Denial of Service (DDoS) attack is an attempt to disrupt the normal traffic of a targeted server, service, or network by overwhelming it with a flood of Internet traffic.
What is data encryption?
Answer: Data encryption is the process of converting plaintext into ciphertext to prevent unauthorized access.
What is a honeypot?
Answer: A honeypot is a security mechanism set to detect, deflect, or counteract attempts at unauthorized use of information systems.
What is a digital certificate?
Answer: A digital certificate is an electronic document used to prove the ownership of a public key.
What is the difference between an ethical hacker and a penetration tester?
Answer: Ethical hackers are authorized to bypass system security to identify potential weak points, while penetration testers specifically focus on testing the security of systems.
What is a VPN tunnel?
Answer: A VPN tunnel is a secure pathway through which data is transmitted across the internet from one network to another.
What are the common types of cyber attacks?
Answer: Common types include phishing, malware, ransomware, SQL injection, DDoS, man-in-the-middle attacks, and more.
What is an SSL certificate?
Answer: An SSL certificate is a digital certificate that provides authentication for a website and enables an encrypted connection.
What is XSS?
Answer: Cross-Site Scripting (XSS) is a type of security vulnerability typically found in web applications. XSS enables attackers to inject client-side scripts into web pages viewed by other users.
What is DNS Spoofing?
Answer: DNS Spoofing, also known as DNS cache poisoning, is a type of attack where corrupt DNS data is inserted into the DNS resolver’s cache, causing the name server to return an incorrect result record.
What is a botnet?
Answer: A botnet is a network of private computers infected with malicious software and controlled as a group without the owners’ knowledge.
What is the principle of least privilege?
Answer: The principle of least privilege is a security concept in which a user is given the minimum levels of access—or permissions—needed to perform their job functions.
What is a security policy?
Answer: A security policy is a set of rules and practices that specify how a system or organization provides security for its information assets.
What is a vulnerability assessment?
Answer: A vulnerability assessment is the process of identifying, quantifying, and prioritizing (or ranking) the vulnerabilities in a system.

What is a patch?
Answer: A patch is a set of changes to a computer program or its supporting data designed to update, fix, or improve it.
What is a backdoor?
Answer: A backdoor is a method of bypassing normal authentication procedures, usually through a secret method of obtaining access.
What is cryptography?
Answer: Cryptography is the practice and study of techniques for securing communication and data in the presence of adversaries.
What is the CIA triad?
Answer: The CIA triad stands for Confidentiality, Integrity, and Availability, which are the three core principles of cybersecurity.
What is data integrity?
Answer: Data integrity refers to the accuracy and consistency of data stored in a database or data warehouse.
What is two-factor authentication?
Answer: Two-factor authentication (2FA) is an additional layer of security used to ensure that people trying to gain access to an online account are who they say they are.
What is a security breach?
Answer: A security breach is an incident that results in unauthorized access to computer data, applications, networks, or devices.
What is a Trojan Horse?
Answer: A Trojan Horse is a type of malware that is often disguised as legitimate software.
What is the difference between a virus and a worm?
Answer: A virus requires a host program to run, whereas a worm is standalone software that replicates itself to spread to other computers.
What is encryption?
Answer: Encryption is the process of encoding information in such a way that only authorized parties can access it.
What is a denial-of-service attack?
Answer: A denial-of-service attack is an attack meant to shut down a machine or network, making it inaccessible to its intended users.
What is penetration testing?
Answer: Penetration testing is a simulated cyber attack against your computer system to check for exploitable vulnerabilities.
What is a security token?
Answer: A security token is a physical device used to gain access to an electronically restricted resource.
What is an attack vector?
Answer: An attack vector is a path or means by which a hacker can gain access to a computer or network server to deliver a malicious payload.
What is identity theft?
Answer: Identity theft is the deliberate use of someone else’s identity, usually as a method to gain a financial advantage.

What is a rootkit?
Answer: A rootkit is a collection of software tools that allow an unauthorized user to gain control of a computer system without being detected.
What is a VPN protocol?
Answer: A VPN protocol is a set of rules that determine how data is transmitted over a VPN connection.
