Similar to the Internet, connectivity in Next Generation Networks such as 4G will be IP-Based. This implies that they inherit all the security problems of the current Internet. Amongst these numerous threats, compromise and resource exhaustion threats which come in the form of Denial of Service attacks, are very common and particularly serious. The severity of such attacks will be fuelled by the development of heterogeneous devices which have several wireless interfaces, as multi-homed devices will be able to send multiple connection requests to the server and thus launch attacks over different access networks. This paper details a new model to address the problem of Denial of Service attacks against the current Internet which limit the accessibility of a server based on its operational scope such that the solution will work effectively in heterogeneous, multi-homed environments. However, Denial of service attacks target the system resources and degrade their performance thus, affecting the Quality of Service’s delivery to the subscribed users. Therefore, the proposed model suggests dealing with security and QoS in an integrated manner by using the concept of Quality of Security Service where security is considered as a Quality of Service’ parameter. This paper furthermore shows how security can be integrated into the infrastructure of future network systems. However, in order to implement the proposed model, it is necessary to enhance current networking infrastructure by extending current services such as the Domain Naming Service and evolving new services such as a Master Locator to support user mobility.
