Croatian Telemedicine Strategy Supports the Multilateral European Dynamic Partnership Work Program Through Cooperative Content Development

ICT platform of the CHIS must be standards-based. Built-in networking mechanisms would virtually partition CHIS into telemedicine, administrative and any other anticipated logical segment. In this way, the needed technical preconditions will be established for implementation of high quality real-time services. Technical preconditions imply guaranteed bandwidth and Quality of Service (QoS) parameters for designated real-time traffic flows. From the architectural perspective, the CHIS communications platform would follow hierarchical, 3-layer structure. Dispersion of network functionalities across access, distribution and core layer would ensure network efficiency and reliability. Physically, CHIS will be formed of a number of Local Area Networks (LAN) integrated into an intranet, by means of Wide Area Network (WAN) resources leased from telecom operator/service provider. In order to build an efficient and high-performance communication infrastructure, traffic demands of implemented applications should be precisely determined. Analytical methods and software tools need to be used for determination of traffic patterns and QoS parameters needed. Calculated results will be exploited in order to define network architecture, to plan network resources, to choose proper networking technology and equipment, and to implement QoS parameters. Openness of the CHIS emphasizes security issues. Common security threats in today’ s networking environments include viruses, Trojans and worms, spam, packet sniffers, IP spoofing , man-in-the-middle attacks, Denial of Service, various application level attacks. These threats can severely disrupt clinical and administrative business processes, consequently leading to the loss of patients, confidence and significant financial costs. CHIS security must be observed as an evolving process, hence defined security policy and mechanisms must be constantly adjusted. A comprehensive approach to information protection must be taken at every potential access point at all CHIS levels. Recognition of potential threats and access points would be the initial step in creating a secure environment. The next step assumes implementation of appropriate network security tools. These include antivirus packages, security agents, AAA (Authentication, Authorization and Accounting) services, dedicated network security devices (firewall, IPS, IDS), and encryption. Only careful planning, precise security policy, strict enforcement and proactive monitoring may produce the needed level of security [1]. Staff education would be carried out constantly.
