A Thorough Evaluation of the Compatibility of an E-Business Security Negotiations Support Tool
"... Abstract—For the benefits of e-business to be fully realized, there are numerous challenges to be over-come particularly with respect to security. Some of the most significant of these difficulties is incurred even before businesses fully enter the joint e-business interactions. A key example is the ..."

is the challenge faced as partnering e-businesses come together initially to share, compare and negotiate on their individual se-curity needs. In previous work, we have proposed a support tool to assist in this activity and stream-line several of the difficult security negotiation tasks which arise. This paper
Effects Of Livelihood Diversification On Food Se- curity Status Of Farm Households In North Gondar
"... ABSTRACT: Although still of central importance, farming on its own is increasingly unable to provide a sufficient means of survival in rural areas. Further, the asset base of farmers is not diversified, so loss of farming productivity during severe drought results in the total loss of assets and hen ..."

and hence results in food insecurity and dependency on food aid. Therefore, it was crucial to identify the causes and consequences of food insecurity; assess the different livelihood strategies and their role to household food security status; and examine the effect of livelihood diversification
Evaluating the Reliability of Credential Hardening through Keystroke Dynamics
- in Software Reliability Engineering, 2006. ISSRE ’06. 17th International Symposium on, 2006
"... Most computer systems rely on usernames and pass-words as a mechanism for authentication and access con-trol. These credential sets offer weak protection to a broad scope of applications with differing levels of sensitivity. Traditional physiological biometric systems such as finger-print, face, and ..."

by incorporating shift-key patterns. The system is capable of operating at various points on a traditional ROC curve depending on application specific se-curity needs. A 1 % False Accept Rate is attainable at a 14% False Reject Rate. An Equal Error Rate of 5 % is suitable for systems requiring a relatively low
Secure and Mobile P2P File Sharing
"... In today’s Internet, a major portion of the total traffic is gen-erated by peer-to-peer applications such as Skype and BitTor-rent. The amount of this traffic has been increasing since the beginning of this decade. At the same time, mobile use of the Internet has become even more popular. New mobile ..."

of mobile devices affect the application design and network architecture choices. We also focus on the security and privacy aspects of mobile P2P networks. Functionality of P2P networks can be divided into two parts, into content location, and into content download. Se-curity needs of both
Access control: Policies, models, and mechanism
- In Foundations of Security Analysis and Design - Tutorial Lectures, R. Focardi and F. Gorrieri, Eds
, 2001
"... Abstract. Access control is the process of mediating every request to resources and data maintained by a system and determining whether the request should be granted or denied. The access control decision is enforced by a mechanism implementing regulations established by a secu-rity policy. Differen ..."

. Different access control policies can be applied, corresponding to different criteria for defining what should, and what should not, be allowed, and, in some sense, to different definitions of what ensuring se-curity means. In this chapter we investigate the basic concepts behind access control design
Towards a Semantic Web Security Infrastructure
- Stanford University, Stanford California
, 2004
"... The move towards supporting more autonomous systems, where decisions are made without direct user intervention, and more complex operating scenarios, where services from multiple organisations form temporary ties to solve particular problems, creates new security challenges. This paper argues that t ..."

that the answers should combine the use of conventional se-curity solutions, such as cryptographic mechanisms, with the ability to reason about security at the semantic level, using appropriate descriptions of security policies and the required tasks. Such reasoning can enable software entities aiming to interact

Abstract Hazardous substances are products that need special attention from the personnel which manipulates them, therefore, there is an increased need for better security management of goods and people in chemical industries. In this paper we propose the design of the Smart Object capable to survey ..."

A Method for Eliciting Security Requirements from the Business Process Models
