What is CyberSecurity?
Cybersecurity is the practice of protecting systems, networks, and data from cyber-attacks. It prevents unauthorized access and data breaches. The goal is to ensure data confidentiality, integrity, and availability.
What are the three pillars of Information Security?
The three pillars are Confidentiality, Integrity, and Availability (CIA). Confidentiality protects access, integrity ensures data accuracy, and availability guarantees data is accessible when needed. These principles form the foundation of information security.
What is malware?
Malware refers to any software intentionally created to cause harm to computers or networks. It includes viruses, Trojans, worms, and ransomware. Malware often aims to steal data or disrupt system functionality.
What is a firewall?
A firewall is a network security tool that regulates traffic flow between a trusted internal network and external sources. It blocks unauthorized access while allowing permitted communication to pass through.
What is phishing?
Phishing is a deceptive tactic to trick people into revealing sensitive information, like passwords or credit card numbers. It often involves fake emails or websites designed to mimic legitimate ones, aiming for identity theft or fraud.
What is the purpose of antivirus software?
Antivirus software identifies, blocks, and removes malicious programs such as viruses and malware. It scans systems to prevent infections and ensures security by regularly updating to combat new threats.
What is encryption?
Encryption converts data into an unreadable format that is only accessible with a decryption key. It protects sensitive information, ensuring privacy and security by preventing unauthorized access.
What is a VPN?
A VPN (Virtual Private Network) creates a secure, encrypted connection over the internet, protecting your data and hiding your IP address. It’s commonly used for privacy and bypassing geographic restrictions.
What is social engineering?
Social engineering manipulates people into disclosing sensitive information by exploiting human behavior, rather than technical weaknesses. Phishing and pretexting are common social engineering tactics.
What is two-factor authentication (2FA)?
Two-factor authentication (2FA) adds an extra security layer by requiring two verification steps, such as a password and a code. It enhances protection against unauthorized access.
Cybersecurity Interview Questions: Scenario Questions for Beginners
Scenario-based questions test how beginners would respond to real-world cybersecurity incidents.
