  • Charging for Network Security Based on Long-Run Incremental Cost Pricing Pricing for the use of the networks is essential in the way that it should be able to reflect the costs benefits imposed on a network when connecting a new generator or demand and to provide forward-looking message to influence the site and size of future network customers. Studies have been extensively carried out over the years to achieve this pricing goal. Few methodologies can directly link nodal generation/demand increment to network long-run marginal/incremental costs.

  • Security has become a major concern for every network administrator. Nearly every day we are bombarded with news articles describing yet another high-profile company that has fallen prey to a network-based attack. To fill in the occasional gap, we hear about new viruses that have been found “in the wild” or about additional software vulnerabilities that someone has figured out how to exploit for personal gain. The network security field has not always been this crazy. Most of us can remember a time when securing a network environment was a far easier task.

  • The purpose of this book is to answer those questions, from the point of view of people who want to use Java, but want to do so reliably, securely and safely. That makes this book different from much recent writing on Java, which focuses, perfectly legitimately, on how a Java system can be broken into and how to avoid those dangers. On the contrary, this book focuses on how Java can be made secure and how to exploit its strengths. The goal is to provide practical help to the various groups involved in making a Java-based application or Web site into an industrial-strength commercial proposit.

  • Attackers can infect your computer with malicious software, or malware, in many different ways. They can take advantage of unsafe user practices and flaws in your computer’s programs (flaws including vulnerabilities and unsecured services and features) and use social engineering (in which an attacker convinces someone to perform an action such as opening a malicious email attachment or following a malicious link). Once your computer is infected, intruders can use the malware to access your computer without your knowledge to perform unwanted actions.

  • Hello, in this module we are going to discuss wireless networking. Specifically, we'll take a look at how wireless technology works, how it is commonly deployed, and the security issues associated with using it. Because wireless communications can penetrate opaque objects such as buildings, the risk of someone accessing a private network increases markedly. With wireless, an attacker does not need to gain access to physical cables or jacks, but only needs to have an antenna and be within range of the transmissions....
