DDoS is a type of cyberattack that attempts to overwhelm a website, network, or server with traffic from multiple sources, making it unavailable to users.
16. What is a session hijacking attack?
Session hijacking is a type of cyberattack where an attacker takes control of a user’s session to execute unauthorized actions or steal sensitive information.
17. What is end-to-end encryption?
End-to-end encryption is a security mechanism that encrypts data on the sender’s device and decrypts it on the recipient’s device, ensuring that only the intended parties can access the data.
18. What is a security policy?
A security policy is a set of rules and guidelines that define how an organization manages information security.
19. What is a digital certificate?
A digital certificate is an electronic document used to verify the identity of a user or system and establish trust in the authenticity of transmitted data.
20. What is a VPN?
A virtual private network (VPN) is a secure network connection that encrypts data transmitted between two devices over the internet.
21. What is a security audit?
A security audit is a comprehensive review of an organization’s security policies, procedures, and systems to assess their effectiveness and identify vulnerabilities.
22. What is the difference between a vulnerability assessment and a penetration test?
A vulnerability assessment is a process of identifying and prioritizing weaknesses in an organization’s systems and networks, while a penetration test aims to exploit the identified vulnerabilities to assess the effectiveness of the security measures.
23. What is a keylogger?
A keylogger is a type of software or device used to record keystrokes on a computer to capture sensitive information, such as passwords and credit card numbers.
24. What is a botnet?
A botnet is a network of infected devices that are controlled by an attacker to execute commands, such as launching DDoS attacks or sending spam emails.
25. What is a digital forensic analysis?
Digital forensic analysis is the process of collecting and analyzing digital evidence to investigate cybercrime and cyberattacks.
26. What is incident response?
Incident response is the process of identifying, analyzing, mitigating, and recovering from cybersecurity incidents.
27. What is a security token?
A security token is a device or application used to generate a unique one-time password that is used for multi-factor authentication.
28. What is biometric authentication?
Biometric authentication uses physical characteristics, such as fingerprints, facial recognition, or iris scans, to authenticate a user’s identity.
29. What is a data breach?
A data breach is an incident where sensitive information, such as personal and financial data, is stolen or exposed to unauthorized parties.
30. What is network segmentation?
Network segmentation is the process of dividing a network into smaller subnetworks to improve security and performance.
31. What is a security clearance?
A security clearance is a level of authorization granted to individuals to access classified information or secured areas.
32. What is an access control list (ACL)?
An access control list is a set of rules or permissions that defines what resources or data a user or device can access on a network.
33. What is a security incident?
A security incident is an event that compromises the confidentiality, integrity, or availability of an organization’s information systems or data.
34. What is a security breach?
A security breach is a successful incident where an attacker gains unauthorized access to an organization’s information systems or data.
35. What is cybersecurity risk management?
Cybersecurity risk management is the process of identifying, assessing, and prioritizing security risks to mitigate potential threats.
36. What is a security baseline?
A security baseline is a set of security standards and configurations that define the minimum level of security requirements for an organization’s systems and networks.
