15. Cloud Security: Measures and practices designed to protect cloud computing environments, data, and applications from cyber threats and unauthorized access.
16. Cryptography: The practice of securing information by converting it into a form that only authorized parties can read or process.
17. Data Breach: An incident where sensitive, confidential, or protected data is accessed, stolen, or released without authorization.
18. Data Encryption: The process of converting plaintext data into ciphertext using an encryption algorithm and a key, making the data unreadable to unauthorized parties.
19. Decryption: The process of converting encrypted data or ciphertext back into its original, readable form.
20. Decoy: A system or resource designed to lure and detect potential attackers or malicious activities.
    
21. Demilitarized Zone (DMZ): A physical or logical network segment that separates an organization's internal network from an untrusted external network.
22. Denial of Service (DoS) Attack: A cyber-attack that aims to make a system, network, or resource unavailable to its intended users by overwhelming it with traffic or requests.
23. Digital Certificate: An electronic document that binds a public key to an identity, used for authentication, secure communication, and data encryption.
24. Digital Signature: A cryptographic mechanism that provides integrity, authentication, and non-repudiation for digital data or documents.
25. Distributed Denial of Service (DDoS) Attack: A type of DoS attack that involves multiple compromised systems or devices flooding a target with traffic or requests.
26. Encryption Key: A piece of information used in encryption algorithms to encode and decode data.
27. End-to-End Encryption: A method of secure communication where data is encrypted on the sender's system and can only be decrypted by the intended recipient's system.
28. Endpoint Security: Measures and tools designed to protect end-user devices, such as laptops, desktops, and mobile devices, from cyber threats and unauthorized access.
29. Ethical Hacking: The practice of legally and ethically attempting to breach computer systems or networks to identify vulnerabilities and improve security.
30. Firewall: A security system that monitors and controls incoming and outgoing network traffic based on predefined security rules.
31. Hashing: A cryptographic process that converts input data of any length into a fixed-size output, known as a hash value or digest.
32. Honeypot: A decoy system designed to attract and study cyber attackers' behaviors and techniques.
33. Identity and Access Management (IAM): A framework and set of processes for managing user identities, access rights, and privileges within an organization.
34. Incident Response: The process of identifying, analyzing, and responding to cybersecurity incidents or breaches.
35. Intrusion Detection System (IDS): A security system that monitors network or system activities for malicious behavior or policy violations.
36. Intrusion Prevention System (IPS): A security system that actively monitors network or system activities and takes action to prevent or mitigate detected threats or attacks.
37. Keylogger: A type of malware that records and transmits keystrokes, capturing sensitive information such as passwords or credit card numbers.
38. Malware: Malicious software designed to cause harm or disrupt computer systems, networks, or devices.
39. Man-in-the-Middle (MitM) Attack: A cyber-attack where an attacker intercepts and relays communication between two parties, potentially eavesdropping or modifying the communication.
40. Multi-Factor Authentication (MFA): A security method that requires two or more authentication factors, such as a password, biometric data, or a security token, for user verification.
41. Network Access Control (NAC): A security solution that enforces policies for controlling access to a network based on predefined criteria, such as user or device identity, compliance status, or security posture.
42. Network Security: Measures and practices designed to protect computer networks and their components from unauthorized access, misuse, or cyber threats.
43. Penetration Testing: A security evaluation method that involves simulating real-world attacks on a computer system or network to identify vulnerabilities and assess the effectiveness of security controls.
44. Phishing: A type of social engineering attack that involves using deceptive emails, websites, or messages to trick users into revealing sensitive information or installing malware.
45. Ransomware: A type of malware that encrypts or blocks access to data or systems, demanding a ransom payment in exchange for decryption or restoration.
46. Risk Assessment: The process of identifying, analyzing, and evaluating potential risks and vulnerabilities in an organization's systems or processes.
47. Rootkit: A type of malware that provides an attacker with privileged access and enables concealment of malicious activities on a compromised system.
48. Sandboxing: A security technique that involves isolating and executing untrusted or potentially malicious code or applications in a controlled and restricted environment.
49. Security Information and Event Management (SIEM): A security solution that collects, analyzes, and correlates log data and security events from various sources to detect and respond to potential threats or incidents.
50. Social Engineering: The practice of manipulating or deceiving individuals into revealing sensitive information or performing actions that compromise security.
