With the rapid development of information technologies and the transition to next-generation networks, computer systems and in particular embedded s- tems are becoming more and more mobile and ubiquitous. They also strongly interact with the physical world. Ensuring the security of these complex and resource-constrained systems is a really challenging research topic. Therefore this Workshop in Information Security Theory and Practices was organized to bring together researchers and practitioners in related areas, and to encourage cooperation between the research and the industrial communities. This was the second edition of WISTP, after the ?rst event in Heraklion, Greece, in 2007. This year again we had a signi?cant number of high-quality submissions coming from many di?erent countries. These submissions re?ected the major topics of the conference, i. e. , smart devices, convergence, and ne- generation networks. Submissions were reviewed by at least three reviewers, in most cases by four, and at least by ?ve for the papers involving Program C- mittee members. This long and rigorousprocess could be achievedthanks to the hard work of the Program Committee members and additional reviewers, listed in the following pages. This led to the selection of high-quality papers that made up the workshop program and are published in these proceedings. A number of posters and short papers were also selected for presentation at the conference. The process was very selective and we would like to thank all those authors who submitted contributions that could not be selected.

While wireless technologies continue to provide an array of new challenges and multi-domain applications for business processes and solutions, there still remains to be a comprehensive understanding of its various dimensions and environments.

Highlighting new trends, applications, developments, and standards, this book is essential for next generation researchers and practitioners in the ICT field.

In order to have a complete understanding of the function that ISA Server plays in network security, it is necessary to first have a broad understanding of what network and Internet security entails, why it is vital, and how it may be achieved by means of an all-encompassing security policy. Only then will you be able to understand how firewalls work and how functions. After that, you will be able to comprehend the operation of ISA in addition to the workings of firewalls. Within the realm of information technology (IT), network security is a pressing problem that is also rapidly becoming into a prominent (and often lucrative) area of specialized knowledge and experience. Users of the internet who are technically savvy frequent in large numbers websites that place a strong emphasis on data protection. There has been a rise in the frequency with which certifications that are concerned with security are adopted. Biometric identification and verification used to be the realm of science fiction writers and maybe a few highly secret government agencies, but in today's day and age, such arcane security measures are considered to be standard operating procedure in corporate America. In spite of all of the attention that is being given to security, many firms continue to install security measures in a way that is almost wholly random. There is no system that has been well-thought-out to ensure that all of the components are compatible with one another, and this is a problem. Only two of the numerous sides that are covered in computer security are the protection of the physical hardware as well as the electrical bits and bytes that make up the information that is stored on the network. Computer security also includes the protection of many other aspects. In the following sentence, we will provide a high-level overview of what we mean when we speak about "security" and how it pertains to your computer network. This will be followed by a review of some of the key points. This term may be a little misleading when it comes to the safety of computers and networks since it indicates a degree of protection that is essentially unreachable in the connectivity-oriented computing world of today. Because of this, the same dictionary 1 | P a ge gives yet another meaning that is unique to computer science. This definition is as follows: "The degree to which a program or device is protected from being used in an unauthorized manner" [italics added]. This definition contains the unstated stipulation that the aims of security and accessibility, the two primary concerns on the minds of many network managers, are, by their very natures, diametrically opposed to one another. This is an implicit caveat in the definition. The accessibility and protection of users' data are often cited as the two most important concerns of network administrators. Your data will have a lower level of protection if it is easier for unauthorized parties to have access to it. In a same vein, if you guard it with a higher level of vigilance, you will make it harder for anybody to have access to it. Every strategy for achieving security entails some level of work to locate a happy medium between the two poles of the spectrum. You will need to familiarize yourself with the terminology that security professionals use in order to appreciate the fundamentals; similarly, this is the case in any other specialized sector that you may be interested in. At the end of this, you will discover a list of some common phrases that you are likely to come across when working in the subject of information technology security. If you are just starting out in the industry, the information on this list will be useful to you. A well-known hacker's slogan is "Hack the world!" Other well-known hacker slogans are "Information wants to be free" and the simpler but more positive "Information wants to be free." The fact of the issue is, however, that it is relevant not only to those people who are trying to acquire access to material that they are not permitted to examine, but also to those people who are attempting to secure themselves from the trespassers. This is because the reality of the matter is that it is applicable to both groups of people. The old adage "Know thy enemy" is still the first and most crucial stage in winning any fight, and network security is a war over who owns and controls the information on your computer. Therefore, it is essential to have a thorough understanding of your adversary. This piece of wisdom has been passed down from generation to generation since the beginning of time. In order to prevent the theft of network resources, damage to those resources, or exposure of those resources when it is not necessary, you need to have a knowledge of who initiates these actions, why they do it, and how they do it.
