Security issues in adaptive distributed systems

Adaptive Distributed Systems (ADSs) are distributed systems that can evolve their behaviors based on changes in their environments. In this work, we discuss security and propose security metrics issues in the context of ADSs. A key premise with adaptation of distributed systems is that in order to detect changes, information must be collected by monitoring the system and its environment. How monitoring should be done, what should be monitored, and the impact monitoring may have on the security mechanism of the target system need to be carefully considered. Conversely, the impact of implementation of security mechanism on the adaptation of distributed system is also assessed. We propose security metrics that can be used to quantify the impact of monitoring on the security mechanism of the target distributed system

Security Analysis of Wireless BAN in e-Health

The Wireless Body Area Network (WBAN) has gained popularity as a new technology for e-Health, and is considered as one of the key research areas in computer science and healthcare applications. WBAN collects patients’ data, monitors constantly their physiological parameters, using small implantable or wearable sensors, and communicates these data using wireless communication techniques in short range. WBAN is playing a huge role in improving the quality of healthcare. Still, due to sensitive and concurrent nature of e-Heath systems, current research has showed that designers must take into considerations the security and privacy protection of the data collected by a WBAN to safeguard patients from different exploits or malicious attacks, since e-Health technologies are increasingly connected to the Internet via wireless communications. In this paper we outline the most important security requirements for WBANs. Furthermore, we discuss key security threats to avoid. Finally, we conclude with a summary of security mechanisms to follow that address security and privacy concerns of WBANs, and need to be explored in an increasingly connected healthcare world
