  1. 2. encryption An encryption method in which two keys (a private key and a public key) are used to encrypt and decrypt a message. Also known as public-key encryption.
  2. 5. The unethical practice of registering domain names very similar to those of high-volume sites in hopes of receiving traffic from users seeking the high-volume site who mistakenly enter an incorrect URL in their browsers.
  3. 8. An encryption method in which the same key is used to encrypt and decrypt a message. Also known as private-key encryption.
  4. 10. A ___ encryption is a method in which hashes are used to verify the integrity of transmitted messages. Also known as one-way encryption.
  5. 15. The right to be ____ is an argument that asks "Do people have the right to remove damaging information about themselves on the Internet so the information can be forgotten?"
  6. 16. The security principle of providing proof that a transaction occurred between identified parties. Repudiation occurs when one party in a transaction denies that the transaction took place.
  7. 19. A security technique designed to prevent access to information by converting it into a scrambled (unreadable) form of text.
  8. 20. Abbreviation for malicious software. Malware is software designed to harm computer systems.
  9. 22. ___ programming is code that provides a temporary solution to a known problem, or bug.
  10. 23. The process of converting encrypted data back to its original form.
  11. 24. A software application secretly placed on a user's system to gather information and relay it to outside parties, usually for advertising purposes.

  1. 1. A digital ____ is a password-protected, encrypted data file containing message encryption, user identification and message text. Used to authenticate a program or a sender's public key, or to initiate SSL sessions. Must be signed by a certificate authority (CA) to be valid.
  2. 3. A self-replicating program or algorithm that consumes system resources.
  3. 4. A security barrier that controls the flow of information between the Internet and a private network. A firewall prevents outsiders from accessing an enterprise's internal network, which accesses the Internet indirectly through a proxy server.
  4. 5. _______ security is a protocol based on SSL 3.0 that provides authentication and encryption, used by most servers for secure exchanges over the Internet.

  6. 7. A malicious program that replicates itself on computer systems, usually through executable software, and causes irreparable system damage.
  7. 8. A digital ____ is a electronic stamp added to a message that uniquely identifies its source and verifies its contents at the time of the signature.
  8. 9. An application that installs hidden services on systems. Illicit servers consist of "client" code and "server" code that enable the attacker to monitor and control the operation of the computer infected with the server code.
  9. 11. The process of verifying the identity of a user who logs on to a system, or the integrity of transmitted data.
  10. 12. A protocol layer that provides authentication and encryption, used by most servers for secure exchanges over the Internet. Superseded by Transport Layer Security (TLS).
  11. 13. A graphic or moving image that appears on your screen when your computer is idle.
  12. 14. A variable value, such as a numeric code, that uses an algorithm to encrypt and decrypt data. Some applications encrypt and decrypt with the same key, whereas other applications use a pair of keys.
  13. 17. A file or collection of tools that resolves system liabilities and improves software performance.
  14. 18. A program disguised as a harmless application that actually produces harmful results.
  15. 21. Acronym for internet control messaging protocol which is a subset of Internet Protocol that is most often used to determine whether a computer can communicate with the rest of the network.
