An Efficient Security System for Mobile Data Monitoring

Abstract

During the last decade, rapid development of mobile devices and applications has produced a large number of mobile data which hide numerous cyber-attacks. To monitor the mobile data and detect the attacks, NIDS/NIPS plays important role for ISP and enterprise, but now it still faces two challenges, high performance for super large patterns and detection of the latest attacks. High performance is dominated by Deep Packet Inspection (DPI) mechanism, which is the core of security devices. A new TTL attack is just put forward to escape detecting, such that the adversary inserts packet with short TTL to escape from NIDS/NIPS. To address the above-mentioned problems, in this paper, we design a security system to handle the two aspects. For efficient DPI, a new two-step partition of pattern set is demonstrated and discussed, which includes first set-partition and second set-partition. For resisting TTL attacks, we set reasonable TTL threshold and patch TCP protocol stack to detect the attack. Compared with recent produced algorithm, our experiments show better performance and the throughput increased 27% when the number of patterns is 106. Moreover, the success rate of detection is 100%, and while attack intensity increased, the throughput decreased.

Towards Smart Healthcare: Patient Data Privacy and Security in Sensor‐Cloud Infrastructure

“…Mobile healthcare, or m-health, technology [67,68] is a rapidly emerging factor facilitating healthcare for better and more efficient services. M-health with cloud computing includes offloading benefits such as reliability improvement, performance improvement, energy savings, ease of software development, and better exploitation of contextual information [24,69]. For instance, Figure 4 shows tremendous achievements by m-health to aid healthcare services through technology in bidirectional perspective (customers and providers): mobile-enabled EHRs, patient portals, secure text messaging, patient monitoring devices, and telemedicine.…”
