Abstract

Network applications in SDN environment operate
without any threat prevention mechanism or access control to
checkmate what functions or operations they can execute within
the network. This gives room for malicious applications to implement
an offensive attack against the network or install exploits
that can compromise the confidentiality, integrity or availability
of network resources. In order to address this problem, this paper
proposes a threat mitigation model based on trust that introduces
a token-based authentication method that enables the controller
to verify and validate every network application that makes
changes in the network. The paper contributes in providing
an authorisation method Boolean Access Matrix that constrains
what operation, functions or privileges every network application
can execute within the network. To assess the trustworthiness
of network applications, a trust evaluation method based on
Subjective Logic Reasoning which is a belief learning model is
proposed. Results from tests and experiments show how scalable
and efficient the proposed trust framework is.
