Home surveillance/monitoring systems are widely used nowadays. An intelligent surveillance system can provide multiple functions for uses. The assumption underlying this thesis project is that a home surveillance system can help people manage their homes better. The thesis presents two investigations into an intelligent home surveillance system implementation. First we will focus on the development of a router platform, which can manage the cameras connected to an intelligent home surveillance system. Such a system will include at least one router, one or more cameras. Some of these cameras will be connected by wireless links. Each camera will be dynamically allocated an IP address. The system will manage and control the various elements of the home surveillance/monitoring system via the network. Second, we will examine potential network security solutions, and choose a suitable solution. A key result of this thesis project is that SRTP and MIKEY are suitable for use in a home surveillance/monitoring system and together they provide authentication and privacy for the information from the camera (and potentially other information). This privacy is an important aspect of a home surveillance/monitoring system, since improper use of this information could be damaging to the homeowner’s privacy and personal integrity. Key words: home surveillance/monitoring system, router platform development, network security, SRTP, MIKEY.

Smartphone usage has been continuously growing in recent times. Smartphones offer Personal Computer (PC) functionality to the end user, hence they are vulnerable to the same sorts of security threats as desktop computers. Cloud computing is a new computing paradigm and a breakthrough technology of recent times. Its growing popularity can be attributed to its ability to transform computing to a utility, scalability, and cost effectiveness. More and more services are predicted to be offered in the cloud in the near future. Due to the resource constraints of smartphones, security services in the form of a cloud offering seems to be a natural fit (as the services could be provided in a very scalable form in the cloud while off-loading the smartphone). This project proposes a generic architecture for providing security services in the cloud for smartphones. To enable the design of this architecture, it is essential to analyze and identify possible security solutions that could be provided as a cloud service to the smartphone. Security requirements of smartphones have been analysed considering the various infection channels for smartphones, attacks and threats encountered in a smartphone environment, smartphone usage

distinguishes from large organizations where there exists minimal security or protection mechanisms. This paper investigates and presents different threats that a network can be exposed to and the common protection techniques that can be applied, with a focus on the network perimeter – specifically the router/firewall between the local area network and the Internet. All Internet connected devices and networks are exposed to and affected by security threats to some degree, hence security is important in almost every type of network. With the constant growth of the Internet the 32-bit addressing scheme ipv4 is proving to be inadequate, and therefore the transition to the 128-bit addressing scheme ipv6 is becoming critical. With ipv6 comes new security threats (while still old threats remain) that requires an understanding of perimeter security. In this paper we secure a home router and describe these steps to enable home and small business owners to secure their IPv6 network.
