The real-world guide to securing Cisco-based IP telephony applications, devices, and networks Cisco IP telephony leverages converged networks to dramatically reduce TCO and improve ROI. However, its critical importance to business communications and deep integration with enterprise IP networks make it susceptible to attacks that legacy telecom systems did not face.

Analyzing Computer Security written by Charles P. Pfleeger and has been published by Prentice Hall Professional this book supported file pdf, txt, epub, kindle and other format this book has been release on 2012 with Computers categories.

In this book, the authors of the 20-year best-selling classic Security in Computing take a fresh, contemporary, and powerfully relevant new approach to introducing computer security. Organised around attacks and mitigations, the Pfleegers' new Analyzing Computer Security will attract students' attention by building on the high-profile security failures they may have already encountered in the popular media. Each section starts with an attack description. Next, the authors explain the vulnerabilities that have allowed this attack to occur. With this foundation in place, they systematically present today's most effective countermeasures for blocking or weakening the attack. One step at a time, students progress from attack/problem/harm to solution/protection/mitigation, building the powerful real-world problem solving skills they need to succeed as information security professionals. Analyzing Computer Security addresses crucial contemporary computer security themes throughout, including effective security management and risk analysis; economics and quantitative study; privacy, ethics, and laws; and the use of overlapping controls. The authors also present significant new material on computer forensics, insiders, human factors, and trust.

Report of a government investigation to better understand the role of digital trade -- domestic commerce and international trade conducted via the Internet -- in the U.S. and global economies, as well as the effects of barriers and impediments to digital trade that impede U.S. access to global markets. The analysis provides findings at three levels: at the firm level, through 10 case studies; at the industry level, through a survey of U.S. businesses; and at the economy-wide level, using computable general equilibrium and econometric models. This analysis shows that digital trade contributes to economic output by improving productivity and reducing trade costs. Digital trade's combined effects of increased productivity and lower trade costs are estimated to have increased U.S. real GDP by $517.1-$710.7 billion (3.4-4.8%). Figures and tables. This is a print on demand report.

Blockbuster lawsuits, artificial intelligence, backroom deals, millions in lobbying dollars and grand Silicon Valley idealism - the story of Google and copyright law is action-packed.

In Google Rules, Joanne E. Gray provides pragmatic strategies for taking up this challenge.

As telecommunication technologies and health apps become more ubiquitous and affordable, they expand opportunities for behavioural and mental health professionals to provide quality care. Telemental health now encompasses the full range of services, including assessment, treatment delivery, psychoeducation, supervision, and consultation. Many of the skills needed for competent telepractice are the same as in conventional in-office care. However, physical distance as well as technology itself can create challenges to safe and ethical practice. For instance, when conducting suicide assessment and intervention via videoconferencing, the clinician must be prepared to involve emergency or support services at the patient's location, while providing all the usual treatment documentation and follow-up. Such challenges are manageable when following the best practices outlined in this book.
