This paper defines and maps all possible threats to broadcasting services. Viewers currently use various types of broadcasting services-including cable TV, IPTV, and mobile TV, among others-and broadcast business operators are now developing the appropriate security mechanisms for each medium to safely and reliably provide broadcasting services to their audiences. Unlike mobile TV, which uses of a public network as in an over-the-top configuration, cable TV and IPTV are basically closed networks in terms of network security. However, they also link with external networks to provide additional services (bidirectional services or commerce-related services). Therefore, broadcast business operators of with various types of broadcast media are susceptible to security threats from which their broadcasting services may come to a halt or may be abused by hackers, such as with well-developed APT attacks, as well as other common external attacks. The common vulnerability scoring system for IT security is used to conduct a quantitative evaluation of the risk to security threats for broadcasting services. We also derive the results of a penetration test for the STB through the results presented with respect to a security threat. This result will help address potential security vulnerabilities in broadcasting services.
