A distributed denial of service (DDoS) attack is a type of DoS attack that uses multiple computers to overwhelm a web application.

14. What is a man-in-the-middle (MitM) attack?

A man-in-the-middle (MitM) attack is an attack that intercepts communication between two parties.

15. What is a phishing attack?

A phishing attack is an attack that attempts to trick a user into giving away sensitive information, such as passwords or credit card numbers.

16. What is a social engineering attack?

A social engineering attack is an attack that uses psychological manipulation to trick a user into giving away sensitive information.

17. What is a brute force attack?

A brute force attack is an attack that attempts to guess a password by trying every possible combination.

18. What is a rainbow table?

Encryption is the process of converting data into a form that cannot be read without a key.

20. What is decryption?

Decryption is the process of converting encrypted data back into its original form.

21. What is a hash function?

A hash function is a function that takes input data and produces a fixed-size output, called a hash.

22. What is a salt?

A salt is a random value that is added to a password before it is hashed, to make it more difficult to crack.

23. What is a certificate authority (CA)?

A certificate authority (CA) is an organization that issues digital certificates, which are used to verify the identity of a website.

24. What is a digital certificate?

A digital certificate is a file that contains information about the identity of a website and the public key used for encryption.

25. What is SSL?

SSL (Secure Sockets Layer) is a protocol for encrypting data sent over the internet.

26. What is TLS?

TLS (Transport Layer Security) is a successor to SSL, used for encrypting data sent over the internet.

27. What is a firewall?

A firewall is a network security system that monitors and controls incoming and outgoing network traffic.

28. What is an intrusion detection system (IDS)?

An intrusion detection system (IDS) is a system that monitors network traffic for signs of unauthorized access or malicious activity.

29. What is an intrusion prevention system (IPS)?

An intrusion prevention system (IPS) is a system that monitors network traffic and takes action to prevent unauthorized access or malicious activity.

30. What is a honeypot?

A honeypot is a decoy system designed to attract attackers and gather information about their methods.

31. What is a vulnerability scanner?

A vulnerability scanner is a tool that scans a network or web application for vulnerabilities.

32. What is a penetration test?

A penetration test is a simulated attack on a network or web application, designed to identify vulnerabilities and test the effectiveness of security measures.

33. What is a security audit?

A security audit is a review of an organization’s security policies and procedures, designed to identify weaknesses and recommend improvements.

34. What is a risk assessment?

A risk assessment is an evaluation of the potential risks to an organization’s assets, such as data or infrastructure.

35. What is a security policy?

A security policy is a set of rules and guidelines that govern the use and protection of an organization’s assets.

36. What is a security incident?

A security incident is an event that violates an organization’s security policies or compromises its assets.

37. What is a security breach?

A security breach is an incident in which an attacker gains unauthorized access to an organization’s assets.

38. What is a security incident response plan?

A security incident response plan is a set of procedures for responding to security incidents, designed to minimize damage and restore normal operations.

39. What is a disaster recovery plan?
