Chapter 7 E-Health Threat Intelligence Within Cyber-Defence Framework for E-Health Organizations Arif Sari and Joshua Sopuru Abstract In recent years, scholarly work on cybersecurity in smart health has gained substantial attention from both practitioners and scholars. This is primarily due to the rapid growth in the field of information, communications and technology, protocols, an important aspect of smart health communication infrastructure. The smart health communication infrastructure is solely developed to provide data communication for specific networks such as wireless body area network (WBAN) which is developed for the health sector. The modern healthcare service delivery eliminates the need for real-time inspection of elderly and attention-need patients; that is, medical experts can monitor such people from a remote location through e-health communication infras- tructure. The developed communication infrastructure is used by e-health organiza- tions to store, process or transfer patient’s data which has high priority and requires confidentiality. The infrastructure used by e-health organizations must restrict unau- thorized access to patient data against any intruder. e-health organizations are a major target for hackers as they hold a huge amount of private data as a source of wealth of information. The proposed security solutions for e-health organizations require specific policy developments and propose solutions for specific security layers. The smart, scalable and adaptable solutions are proposed by researchers to overcome several security challenges in e-health organizations. Some of the proposed solutions provide open use and sharing of critical e-health data without compromising patients’ rights to privacy and confidentiality. The deployment of these solutions faces several problems since hackers targeting network layer of these models. Development of new attack methodologies and technological enhancements strengthens hackers to attack with different motivations and compromise e-health organizations’ private data. For this reason, a new security framework is necessary for e-health organiza- tions’ communication infrastructure. The privacy of the patient’s health data must be carefully addressed while developing a new framework. In order to maximize the healthcare quality and minimize the e-health cost, the ultimate goal of this chapter is A. Sari (B ) · J.
