    (b) describe the way in which it works, and
    (c) outline some of the ways in which this security measure can be circumvented.

  2. Investigate the concept of "phishing", and hence:
    (a) describe how it represents a security risk (with reference to examples), and

  3. With regard to consumer anti-virus software:
    (a) identify three real-world examples that can be purchased by consumers,
    (b) describe the process of "signature-based detection", and
    (c) explain how "file emulation" is able to distinguish between malicious and innocuous software.
