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.
