  1. Assymmetric encryption is the process of
    encrypting a message in one-way process so that it can never be decrypted.
    encrypting a message to produce a unique smaller text string.
    encrypting a message using one key and decrypting it with the same key.
    encrypting a message using one key and decrypting it with another.
    encrypting a message then encrypting it further using another key.

    SSL
    PPPoE
    HTTPS
    OCSP
    ICMP
  3. The defining factor of a "trojan horse" is that it
    consumes system resources such as disc space.
    attempts to hide its presence from anti-virus programs.
    resides in the boot sector of a floppy disc.
    is usually sent as an attachment to an E-mail.
    causes damage while masquerading as something else.

  4. The application iptables is used to block certain connections on

  7. Which of the following is true about SSL and TLS?
    SSL and TLS are complementary protocols that together encrypt transactions.
    SSL is the successor to TLS, although it is still often referred to as TLS.
    TLS is the successor to SSL, although it is still often referred to as SSL.
    SSL involves the use of digital certificates but TLS does not.
    TLS involves the use of digital certificates but SSL does not.

    establish a secure transaction with a server.
    encrypt packets before transmission.
  9. What is a firewall?
    A device that encrypts transmissions.
    A device that detects packet sniffing attacks.
    A device used to detect patterns in traffic flow into and out of a network.
    A device that encloses packets within a protocol to render them immune from corruption.
    A device used to protect a local network from unwanted external traffic.
  10. Which of the following statements about digital certificates is NOT true?
    They are issued by trusted third parties such as Verisign.
    They contain the name, contact details and digital signature of the institution that commissioned the certificate.
