  1. 3. High-speed data transmission systems using light pulses through glass fibers, which are very difficult to tap or intercept directly.
  2. 4. An active security tool that monitors network traffic and automatically blocks identified threats or attacks.
  3. 6. A legal and security service that provides proof of data origin or delivery so that a user cannot successfully deny having performed an action.
  4. 8. Guarantees that data remains accurate, complete, and trustworthy by preventing unauthorized alterations.
  5. 10. A monitoring tool that detects suspicious network traffic or policy violations and alerts administrators.
  6. 11. The probability that a threat will exploit a vulnerability and cause harm to an asset or organization.
  7. 12. The process of reducing the likelihood or impact of a security risk through controls and safeguards.
  8. 13. Ensures that sensitive data is kept private and accessed only by authorized individuals.
  9. 15. Physical local area networks (LAN’s) that use cables (like Ethernet) rather than wireless signals, reducing remote interception risks.
  10. 16. Methods used to verify the claimed identity of a user, device, or system before granting access.
  11. 17. Ensures that systems, networks, and data are up and running for authorized users whenever required.

  1. 1. Refers to data storage media (like external hard drives or tapes) physically disconnected from any network to protect against remote cyberattacks and ransomware.
  2. 2. That authorized user can reach and use data or systems when needed without unauthorized interference
  3. 5. Software designed to detect, quarantine, and remove malicious software like viruses, worms, and trojans from a system.
  4. 7. A foundational security model based on three core principles: Confidentiality, Integrity, and Availability
  5. 9. A network security device or software that filters incoming and outgoing traffic based on predetermined security rules.
  6. 14. An identification verification method requiring two distinct forms of evidence (such as a password plus a mobile text code) before access is granted.
