Performance models of a proxy cache server: The impact of multimedia traffic [An article from: European Journal of Operational Research] [HTML] [Digital]

Description:
We propose a multi-class queuing network model to study the impact of multimedia traffic on the overall response times to Web requests for cases with and without a proxy cache server (PCS). We find that an increase of multimedia traffic percentage will significantly impact the response times for both cases with and without a PCS. The PCS ”hit rate” is identified as one of the factors that impact the performance of a PCS for multimedia traffic. Further, we find that it may not pay to choose an overly-powerful PCS, as the marginal reduction in the overall response time cannot be justified. We show that the required time to travel through the client network represents the dominant factor of overall response time. Although the firm’s network bandwidth does not impact the decision of whether to install a PCS, improving it has a significant benefit of shortening the overall response time to users’ Web requests.

Testing Code Security [Hardcover]

Product Description
The huge proliferation of security vulnerability exploits, worms, and viruses place an incredible drain on both cost and confidence for manufacturers and consumers. The release of trustworthy code requires a specific set of skills and techniques, but this information is often dispersed and decentralized, encrypted in its own jargon and terminology, and can take a colossal amount of time and data mining to find.

Written in simple, common terms, Testing Code Security is a consolidated resource designed to teach beginning and intermediate testers the software security concepts needed to conduct relevant and effective tests. Answering the questions pertinent to all testing procedures, the book considers the differences in process between security testing and functional testing, the creation of a security test plan, the benefits and pitfalls of threat-modeling, and the identification of root vulnerability problems and how to test for them. The book begins with coverage of foundation concepts, the process of security test planning, and the test pass. Offering real life examples, it presents various vulnerabilities and attacks and explains the testing techniques appropriate for each. It concludes with a collection of background overviews on related topics to fill common knowledge gaps. Filled with cases illustrating the most common classes of security vulnerabilities, the book is written for all testers working in any environment, and it gives extra insight to threats particular to Microsoft Windows® platforms.

Providing a practical guide on how to carry out the task of security software testing, Testing Code Security gives the reader the knowledge needed to begin testing software security for any project and become an integral part in the drive to produce better software security and safety.

Applied Security Visualization [Paperback]

Product Description

APPLIED SECURITY VISUALIZATION

“Collecting log data is one thing, having relevant information is something else. The art to transform all kinds of log data into meaningful security information is the core of this book. Raffy illustrates in a straight forward way, and with hands-on examples, how such a challenge can be mastered. Let’s get inspired.”

–Andreas Wuchner, Head of Global IT Security, Novartis

Use Visualization to Secure Your Network Against the Toughest, Best-Hidden Threats

As networks become ever more complex, securing them becomes more and more difficult. The solution is visualization. Using today’s state-of-the-art data visualization techniques, you can gain a far deeper understanding of what’s happening on your network right now. You can uncover hidden patterns of data, identify emerging vulnerabilities and attacks, and respond decisively with countermeasures that are far more likely to succeed than conventional methods.

In Applied Security Visualization, leading network security visualization expert Raffael Marty introduces all the concepts, techniques, and tools you need to use visualization on your network. You’ll learn how to identify and utilize the right data sources, then transform your data into visuals that reveal what you really need to know. Next, Marty shows how to use visualization to perform broad network security analyses, assess specific threats, and even improve business compliance.

He concludes with an introduction to a broad set of visualization tools. The book’s CD also includes DAVIX, a compilation of freely available tools for security visualization.

You’ll learn how to:

• Intimately understand the data sources that are essential for effective visualization

• Choose the most appropriate graphs and techniques for your IT data

• Transform complex data into crystal-clear visual representations

• Iterate your graphs to deliver even better insight for taking action

• Assess threats to your network perimeter, as well as threats imposed by insiders

• Use visualization to manage risks and compliance mandates more successfully

• Visually audit both the technical and organizational aspects of information and network security

• Compare and master today’s most useful tools for security visualization

Contains the live CD Data Analysis and Visualization Linux (DAVIX). DAVIX is a compilation of powerful tools for visualizing networks and assessing their security. DAVIX runs directly from the CD-ROM, without installation.

Raffael Marty is chief security strategist and senior product manager for Splunk, the leading provider of large-scale, high-speed indexing and search technology for IT infrastructures. As customer advocate and guardian, he focuses on using his skills in data visualization, log management, intrusion detection, and compliance. An active participant on industry standards committees such as CEE (Common Event Expression) and OVAL (Open Vulnerability and Assessment Language), Marty created the Thor and AfterGlow automation tools, and founded the security visualization portal secviz.org. Before joining Splunk, he managed the solutions team at ArcSight, served as IT security consultant for PriceWaterhouseCoopers, and was a member of the IBM Research Global Security Analysis Lab.
