2. Malware: Short for malicious software, refers to any software designed to harm or exploit a computer system or network.

3. Phishing: A type of cyber attack where an attacker sends a fraudulent email or message, typically impersonating a trustworthy source, in order to trick the recipient into disclosing sensitive information or downloading malware.

4. Encryption: The process of encoding data to protect it from unauthorized access or modification.

5. SSL/TLS: Secure Sockets Layer/Transport Layer Security, a protocol for securing communication between devices over the internet.

6. Vulnerability: A weakness or flaw in a computer system or network that can be exploited by attackers to gain unauthorized access or cause damage.

7. Penetration testing: Also known as pen testing, is the practice of testing a computer system or network for vulnerabilities by simulating an attack.

8. DDoS: Distributed Denial of Service, a type of cyber attack that floods a network or website with traffic, causing it to become unavailable to legitimate users.

9. Cybersecurity incident: Any event that compromises the confidentiality, integrity, or availability of information.

10. Zero-day vulnerability: A vulnerability that is unknown to software developers or vendors, and therefore has no patch or fix available.

11. Botnet: A network of compromised computers or devices controlled by a single attacker, typically used to carry out malicious activities such as DDoS attacks.

12. Honeypot: A decoy computer system or network designed to attract attackers and gather information about their methods and tactics.

13. Patch: A software update or fix that addresses known vulnerabilities or bugs.

14. Two-factor authentication: A security measure that requires users to provide two forms of identification, typically a password and a one-time code, to access a system or account.

15. DNS: Domain Name System, a system that translates domain names into IP addresses, allowing devices to communicate over the internet.

16. Ransomware: A type of malware that encrypts a victim's files or data and demands payment in exchange for the decryption key.

17. VPN: Virtual Private Network, a secure connection between devices over the internet that encrypts all data transmitted between them.

18. Social engineering: A type of attack that exploits human behavior to gain access to sensitive information or systems.

19. Password cracking: The process of guessing or cracking a password to gain unauthorized access to a system or account.

20. Incident response: The process of responding to and mitigating the impact of a cybersecurity incident.

21. Cyber hygiene: The practice of maintaining good cybersecurity habits, such as regularly updating software and using strong passwords.

22. Bot: A computer program that performs automated tasks, often used to carry out malicious activities.

23. SSL certificate: A digital certificate that verifies the identity of a website and encrypts data transmitted between the website and the user.

24. Brute force attack: A type of attack that uses automated software to try every possible combination of characters until the correct password is found.

25. DNS poisoning: A type of attack that redirects a user's web traffic to a fake website, typically used for phishing or malware distribution.

26. Trojan horse: A type of malware that appears to be legitimate software but is actually designed to carry out malicious activities.

27. Social media engineering: A type of social engineering that uses social media platforms to gain access to sensitive information or systems.

28. Encryption key: A unique code or password used to encrypt and decrypt data.

29. Firewall rule: A specific set of instructions that determines how a firewall should behave when handling network traffic.

30. Network security: The practice of protecting computer networks from unauthorized access, use, or destruction.

31. Antivirus software: A type of software designed to detect and remove malware from a computer system.

32. Adware: A type of malware that displays unwanted advertisements or pop-ups on a user's device.

33. Spam: Unsolicited emails or messages that are typically sent in bulk and often contain fraudulent or malicious content.

34. Packet sniffer: A type of software that captures and analyzes network traffic.

35. Spoofing: A type of attack where an attacker disguises their identity or network address to gain unauthorized access.

36. SQL injection: A type of attack where an attacker inserts malicious code into a website or application, typically through a form or search field, in order to gain unauthorized access to a database.

37. Rootkit: A type of malware that hides its presence from the user and other software, often used to gain persistent access to a system or network.

38. White hat hacker: A hacker who uses their skills for ethical purposes, such as identifying and fixing vulnerabilities in a system or network.

39. Black hat hacker: A hacker who uses their skills for malicious purposes, such as stealing sensitive information or disrupting systems.

40. Gray hat hacker: A hacker who uses their skills for both ethical and unethical purposes, depending on the situation.

41. Man-in-the-middle attack: A type of attack where an attacker intercepts communication between two parties, typically to steal sensitive information or modify the content of the communication.

42. Digital certificate: A digital file that contains information about the identity of a website or organization and is used to establish secure communication.

43. Botmaster: The person or group who controls a botnet.

44. WPA/WPA2: Wi-Fi Protected Access/Wi-Fi Protected Access II, a security protocol for wireless networks that provides stronger encryption than WEP.

45. Spoofed email: An email that appears to be from a trusted source but is actually sent by an attacker.

46. Multi-factor authentication: A security measure that requires users to provide more than two forms of identification, such as a fingerprint or facial recognition.

47. Backup and recovery: The process of creating and maintaining backups of data to protect against data loss or corruption.

48. Password manager: A type of software that securely stores and manages passwords.

49. Security audit: The process of evaluating and assessing the security of a system or network.

50. Digital forensics: The process of collecting, analyzing, and preserving digital evidence in order to investigate cybercrime.
