Questions and Answers

What is a defining characteristic of worms compared to viruses?

  • Worms are always attached to legitimate programs
  • Worms always require user initiation to activate
  • Worms primarily target end devices
  • Worms can run by themselves without requiring a host program (correct)
  • How does a Trojan horse operate?

  • It requires user initiation to activate
  • It primarily targets executable files

    Study Notes

    Malware Characteristics

    • A defining characteristic of worms compared to viruses is that worms are self-replicating and don't require a host program to spread.
    • Viruses differ from worms in that they require a host program or file to attach themselves to and replicate.
    • A key characteristic of worms is that they can travel from computer to computer without the need for human interaction.

    Trojan Horse Operation

    • A Trojan horse operates by disguising itself as a legitimate program or file, but actually contains malicious code that can harm a computer system.

    Viruses vs. Trojan Horses

    • Viruses differ from Trojan horses in that viruses replicate themselves by attaching to other programs or files, whereas Trojan horses deceive users into executing the malicious code.

    Cryptography

    Historical Origin

    • The historical origin of cryptography dates back to ancient civilizations, where messages were concealed or encrypted to protect secrecy and integrity.

    Purpose of Cryptography

    • The main purpose of modern cryptography is to protect the confidentiality, integrity, and authenticity of data.

    Cryptology and Ciphers

    • The concept of cryptology encompasses the study of encryption and decryption techniques, including the use of specific algorithms, called ciphers, to transform plaintext into unreadable ciphertext.
    • The purpose of using a specific algorithm, called a cipher, in encryption is to transform plaintext into unreadable ciphertext.

    Modern Cryptography

    • The primary objective of making data computationally secure in modern cryptography is to ensure that even with significant computational resources and time, it is impossible to break the encryption without the decryption key.
