b) Other than security concerns, privacy is considered a core value and is recognized either implicitly or explicitly as a fundamental human right. Privacy-enhancing technologies (PETs) can be defined as technologies that enforce legal privacy principles in order to protect and enhance the privacy of users of information technology. Research and discuss three PETs which can be used on the Internet. Use examples to illustrate your answer. [5 marks]


a) Wireless sensor networks (WSNs) can be described as a network of nodes that makes a collaborative effort in sensing data around its periphery and its surrounding environment. Research into the area of WSNs and understand the WSN architecture and protocol stack. Discuss three different types of threats and vulnerabilities which can be used to attack the WSN. Give your recommendations on how the threats and vulnerabilities can be mitigated for the WSN. [5 marks].


This assessment task will assess the following learning outcomes:
