Preface During the past century, the impact of mathematics on humanity has been more tremendous than ever since Galileo's agonizing fight against the old establishment and the revolution which physics experienced after Newton's subsequent synthesis. At the beginning of the last century, mathematical ideas and techniques were spread to theoretical and applied physics by the influence of two of the greatest mathematicians of all times, D. Hilbert and H. Poincar6, being then at the zenith of

11 types of assets; people, organizations, systems, software, databases, networks, services, data, computing devices, circuits, and websites (Halberdier, Waltermire, and Wunder, 2011). This list is more extensive than the categories discussed, for the sake of brevity, but it might be helpful to enterprise employees seeking to identify different assets. Hardware represents a large investment for businesses. Servers, network devices, cables, workstations, and mobile devices can cost enterprise businesses

WHITE PAPER BIDIRECTIONAL FORWARDING DETECTION FOR OSPF Fast Failure Detection to Speed Network Convergence OVERVIEW In both Enterprise and Service Provider networks, the convergence of business-critical applications onto a common IP infrastructure is becoming more common. Given the criticality of the data, these networks are typically constructed with a high degree of redundancy. While such redundancy is desirable, its effectiveness is dependant upon the ability of individual network devices

rate” of new viruses is high and increasing due to global connectivity, and technology improvements can accelerate their spread. In response to this threat, some contemporary research efforts are aimed at creating computer virus immune systems. This paper analyses the computer viruses and attacks and also some countermeasures to prevent them. In particular, we discuss Intrusion Detection and Prevention techniques for handling web based attacks and to patch up different kinds of vulnerabilities in computer
