Book SynopsisThe first six papers deal with computer security technology that operates in rapidly changing environments and has to adapt to their shifting conditions. The technology or application envisaged in the second six operates or assumes a static outcome that can, for instance, be used forensically. The second half of the book contains a proposal to quantify the time scales on which IT security lives may be a major contribution of this volume. The authors identify three main axes. First, the time scale of practical relevance. It denominates approximately the middle of the time range during which the problem treated by the technology becomes imminent to the IS&T community, through the demands of the market. Second, the technological research and development (R&D) time scale. It is a forecast of when the technological solution will be "there". This means in effect the first of two milestones in technology evolution: a) when a technology has made the breakthrough to be in principle, ie: theoretically and economically applicable and viable, and b) when it is matured to reach prevalence in IS&T, ie: to become textbook standard. The second point in time hinges obviously on external factors not amenable to analysis within the discipline proper. Third, we have the event horizon of the technology in question. That deals with the issue of the sustainability of the solution: May it be surpassed by the skills of attackers using advances in other areas? Can it be foreseen that it will be overcome by even better solutions?

Book SynopsisCyber analysis and warning capabilities are critical to thwarting computer-based (cyber) threats and attacks. The Department of Homeland Security (DHS) established the United States Computer Emergency Readiness Team (US-CERT) to, among other things, co-ordinate the nation''s efforts to prepare for, prevent, and respond to cyber threats to systems and communications networks. The authors'' objectives were to (1) identify key attributes of cyber analysis and warning capabilities, (2) compare these attributes with US-CERT''s current capabilities to identify whether there are gaps, and (3) identify US-CERT''s challenges to developing and implementing key attributes and a successful national cyber analysis and warning capability. To address these objectives, the authors identified and analysed related documents, observed operations at numerous entities, and interviewed responsible officials and experts.

Book SynopsisThe objective of computer security varies and can include protection of information from theft or corruption, or the preservation of availability, as defined in the security policy. Computer security imposes requirements on computers that are different from most system requirements because they often take the form of constraints on what computers are not supposed to do. This makes computer security particularly challenging because it is hard enough just to make computer programs do everything they are designed to do correctly. Furthermore, negative requirements are deceptively complicated to satisfy and require exhaustive testing to verify, which is impractical for most computer programs. Computer security provides a technical strategy to convert negative requirements to positive enforceable rules. This book presents the latest research from around the globe in this ever-changing field.

Book SynopsisEver get the feeling you are being watched? The thieves that steal identities are using cutting-edge, high-tech tools that can take one fact from a social media site, another from an online travel survey, a third from a purchase made via the internet and even access highly confidential medical records. Little by little they piece together your buying habits, your religious and school affiliations, the names of your family and pets, your political views, your driving habits, the places you have vacationed, and much, much more. This is not science fiction and this is not the future, this is what is happening to each and every one of us now - today. And although the vast majority of adults say they are concerned about providing personal information online, nearly 1/3 say they have never used a privacy setting on their computer, never inquired about the charities to whom they donate their money, never worried about someone accessing their medical information and never thought twice about giving a financial institution their social security number over the internet. The Audacity to Spy, written by an attorney with an interest in privacy laws and legislation and her grandmother who is an experienced Information Analyst, reveals the ways in which your identity and personal data have been stolen by various sources. Yes, you should be concerned about the NSA and other government agencies having your phone logs and emails; but you should worry more about the insidious data brokers that are collecting information about you every time you log on to your laptop, use your cell phone, access an app, or use your GPS. Companies are collecting a variety of data about you, combining it with location information, and using it to both personalise their own services and to sell to other advertisers for behavioural marketing. Law enforcement agencies are tracking your car and insurance companies are installing devices to monitor your driving. Clerks are making copies of your credit cards. And if that wasn''t enough, the FBI has reported that hackers have been discovered embedding malicious software in two million computers, opening a virtual door for criminals to rifle through users'' valuable personal and financial information. More than warning you about the ways your data can be stolen, at the end of each chapter are suggestions for limiting the amount of personal data that is available to be seized and divulged. Can you completely cut off the flow of information about yourself? The answer is no, not completely - there is already too much data out there and increasingly sophisticated ways to obtain bits and pieces. But knowing how it is collected, and by whom, gives you the power to control sensitive information and determine how much of your life you wish to expose to those more than willing to exploit it.

Book SynopsisIn introducing the National Security Commission on AI''s final report, Eric Schmidt, former Google CEO, and Robert Work, former Deputy Secretary of Defense, wrote: The human talent deficit is the government''s most conspicuous AI deficit and the single greatest inhibitor to buying, building, and fielding AI-enabled technologies for national security purposes. Drawing upon three decades of leading hundreds of advanced analytics and AI programs and projects in government and industry, Chris Whitlock and Frank Strickland address in this book the primary variable in the talent deficit, i.e., large numbers of qualified AI leaders.The book quickly moves from a case for action to leadership principles and practices for effectively integrating AI into programs and driving results in AI projects. The chapters convey 37 axioms - enduring truths for developing and deploying AI - and over 100 leader practices set among 50 cases and examples, 40 of which focus on AI iTable of ContentsForewordIntroduction Chapter 1.

Book SynopsisCisco routers are used widely both on the Internet and in corporate intranets. At the same time, the Cisco Internet Operating System (IOS) has grown to be very large and complex, and Cisco documentation fills several volumes. Cisco IOS Access Lists focuses on a critical aspect of the Cisco IOS--access lists. Access lists are central to the task of securing routers and networks, and administrators cannot implement access control policies or traffic routing policies without them. Access lists are used to specify both the targets of network policies and the policies themselves. They specify packet filtering for firewalls all over the Internet. Cisco IOS Access Lists covers three critical areas: *Intranets. The book serves as an introduction and a reference for network engineers implementing routing policies within intranet networking. * *Firewalls. The book is a supplement and companion reference to books such as Brent Chapman's Building Internet Firewalls. Packet filtering is an integral part of many firewall architectures, and Cisco IOS Access Lists describes common packet filtering tasks and provides a "bag of tricks" for firewall implementers. *The Internet. This book is also a guide to the complicated world of route maps. Route maps are an arcane BGP construct necessary to make high level routing work on the Internet. Cisco IOS Access Lists differs from other Cisco router titles in that it focuses on practical instructions for setting router access policies. The details of interfaces and routing protocol settings are not discussed.Table of ContentsPreface 1. Network Policies and Cisco Access Lists Policy sets The policy toolkit 2. Access List Basics Standard access lists Extended access lists More on matching Building and maintaining access lists Named access lists 3.
