Findings – SSM was particularly useful for exploring the holistic information security issues, enabling models to be constructed which were valuable analytical tools and easily understood by stakeholders, which increased the receptiveness of the bank, and assisted with member validation. Significant risks were apparent from internal sources with weaknesses in aspects of governance and security ...

This paper examines the theory, application, and results for a Reputation-Based Internet Protocol Security (RIPsec) framework that provides security for a Mobile Ad-hoc Network (MANET) operating in a hostile environment. While there has been significant research in MANET security, the research has tended to address subsets of the overall security challenge. RIPsec leverages existing technologie...

The objective of this article was to describe 1) the validation of 2 similar but not identical food security modules used to collect data from 2 vulnerable populations, southern Lebanon residents (n = 815) and Palestinian refugees in Lebanon (n = 2501), and 2) the development and validation of an Arab Family Food Security Scale (AFFSS). The surveys used a cluster-randomized sampling design. The...

Wireless sensor networks (WSNs) consists of small nodes with constrain capabilities. It enables numerous applications with distributed network infrastructure. With its nature and application scenario, security of WSN had drawn a great attention. In malicious environments for a functional WSN, security mechanisms are essential. Malicious or internal attacker has gained attention as the most chal...

In view of the present cloud security problem has increasingly become one of the major obstacles hindering the development of the cloud computing, put forward a kind of memory based on Xen cloud environment security isolation technology implementation. And based on Xen virtual machine monitor system, analysis of the model of memory virtualization is implemented, using Xen memory virtualization ...

A deniable cryptosystem allows a sender and a receiver to communicate over an insecure channel in such a way that the communication is still secure even if the adversary can threaten the parties into revealing their internal states after the execution of the protocol. This is done by allowing the parties to change their internal state to make it look like a given ciphertext decrypts to a messag...

Wireless mesh networks (WMNs) have emerged as a key technology for next generation wireless networks and provide a low-cost and convenient solution to the last-mile problem. Security and privacy issues are of paramount importance to WMNs for their wide deployment and for supporting service-oriented applications. Moreover, to support real-time services, WMNs must also be equipped with secure, re...

Even in the most secure organizations, information security threats and vulnerabilities are increasing over time. Vulnerabilities are increasing with the complexity of internal infrastructures; complex structures have more single points of failure, and this in turn increases the risk of multiple simultaneous failures. Organizations are adopting new, untried, and partially tested products at eve...
