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.
