The paper ``Access Controls for Open Architecture in Intelligent Networks'' [16] provides the following description of Intelligent Networks (IN).
An Intelligent Network (IN) is a switched network whose service control is removed from the individual switches and whose service definition can be programmable. It aims at rapid and economical service provisioning and facilitates customer control of network services.IN comes from the industry and ONA comes from the regulators. For the most part, IN and ONA have been investigated separately [16].
The opening of Intelligent Networks introduces significant security and integrity problems [16]. The report ``The Impact of Intelligent Networks (IN) on NS/EP Telecommunications'' presents an assessment of vulnerabilities and interoperability issues associated with IN technology [14]. The software-dependency of the Intelligent Network and the openness of its architecture brings expanded security concerns to the Government and Industry [14].
The IN concept allows ESPs to program their own enhanced services and IN will provide customized software-controlled network services that can be flexibly, rapidly, and cost effectively configured by the customer in response to unique requirements independent of service provider activities [14]. As Intelligent Network concepts are merged into networks based on ONA requirements, many vulnerabilities will result.
