SQL server is the most widely used database platform in the world, and a large percentage of these databases are not properly secured, exposing sensitive customer and business data to attack. In Securing SQL Server, 2e, readers learn about the potential attack vectors that can be used to break into SQL server databases as well as how to protect databases from these attacks. In this book written by Denny Cherry, a Microsoft SQL MVP and one of the biggest names in SQL server today, readers learn how to properly secure a SQL server database from internal and external threats using best practices as well as specific tricks the authors employ in their roles as database administrators for some of the largest SQL server deployments in the world. "Denny Cherry is what would happen if Bill Gates and AC/DC got together to create a sibling. He's a bare-knuckles, no holds-barred technologist, and you can bet that if he tells you that something does or doesn't work, he's speaking from experience. Active in the community, his passion is sharing. You'll enjoy this book."--Buck Woody, Senior technology Specialist, MicrosoftPresents hands-on techniques for protecting your SQL Server database from intrusion and attackProvides the most in-depth coverage of all aspects of SQL Server database security, including a wealth of new material on Microsoft SQL Server 2012 (Denali)Explains how to set up your database securely, how to determine when someone tries to break in, what the intruder has accessed or damaged, and how to respond and mitigate damage if an intrusion occurs

Cybercrime Investigation Case Studies is a "first look" excerpt from Brett Shavers' new Syngress book, Placing the Suspect Behind the Keyboard. Case studies are an effective method of learning the methods and processes that were both successful and unsuccessful in real cases. Using a variety of case types, including civil and criminal cases, with different cybercrimes, a broad base of knowledge can be gained by comparing the cases against each other. The primary goal of reviewing successful cases involving suspects using technology to facilitate crimes is to be able to find and use the same methods in future cases. This "first look" teaches you how to place the suspect behind the keyboard using case studies.

The Smart Grid security ecosystem is complex and multi-disciplinary, and relatively under-researched compared to the traditional information and network security disciplines. While the Smart Grid has provided increased efficiencies in monitoring power usage, directing power supplies to serve peak power needs and improving efficiency of power delivery, the Smart Grid has also opened the way for information security breaches and other types of security breaches. Potential threats range from meter manipulation to directed, high-impact attacks on critical infrastructure that could bring down regional or national power grids. It is essential that security measures are put in place to ensure that the Smart Grid does not succumb to these threats and to safeguard this critical infrastructure at all times. Dr. Florian Skopik is one of the leading researchers in Smart Grid security, having organized and led research consortia and panel discussions in this field. Smart Grid Security will provide the first truly holistic view of leading edge Smart Grid security research. This book does not focus on vendor-specific solutions, instead providing a complete presentation of forward-looking research in all areas of Smart Grid security. The book will enable practitioners to learn about upcoming trends, scientists to share new directions in research, and government and industry decision-makers to prepare for major strategic decisions regarding implementation of Smart Grid *** the most current and leading edge research on Smart Grid security from a holistic standpoint, featuring a panel of top experts in the *** coverage of risk management, operational security, and secure development of the Smart *** key technical topics, including threat types and attack vectors, threat case studies, smart metering, smart home, e- mobility, smart buildings, DERs, demand response management, distribution grid operators, transmission grid operators, virtual power plant

ACQUISITION AND DISPLAY OF RADIATION-DOSE DISTRIBUTIONS USING MICROcomputer technology

引用

MEDICAL PHYSICS 1988年第6期15卷 924-929页

作者： ANTOLAK, J MAH, E BATTISTA, JJ SCRIMGER, JW Department of Medical Physics Cross Cancer Institute 11560 University Avenue Edmonton Alberta Canada T6G 1Z2

In the commissioning or quality assurance of a medical linear accelerator or a computerized radiotherapy planning system, the traditional approach usually consists of acquiring and comparing one-dimensional dose profiles. This methodology is tedious and incomplete since only a portion of the radiation field can realistically be sampled. We have developed an automated measurement system which allows efficient measurement and display a complete two-dimensional dose distributions. The general purpose microcomputer used (IBM PC/XT compatible) can be interfaced economically to any water phantom dosimetry system equipped with a three axis scancontroller, and can also communicate data to the treatment planning system. This allows for direct comparison of measured with computed dose distributions, thus revealing discrepancies in the dose computation algorithms used. In this paper, we describe the interface between the microcomputer, a conventional water dosimetry system (Therados RFA-3), and a treatment planning computer. We report our early experience with acquiring dose distributions and show sample comparisons with computed results for megavoltage electron beams incident on homogeneous and heterogeneous systems.
