It is designed for students who have not taken any previous training courses about the ProxySG. Students should be familiar with basic networking concepts, such as local-area networks (LANs), the Internet, security, and IP protocols. A basic knowledge of authentication methods is also a plus. After studying this course, you will understand: • Key concepts of network security and wide-area network (WAN) optimization. • The major functions of the ProxySG, how they work, and how to administer them. • How the ProxySG interfaces with other Blue Coat products. • How to get service and support from Blue Coat. By completing this course and passing an online exam, you can become a Blue Coat Certified Proxy Administrator. Applicable Software Versions This course is based on version 6.2 of the SGOS operating system that is used on the ProxySG. If your organization uses an earlier version of SGOS, some features described in this course might not work as described here, and the appearance and functionality of screens, menus, commands, and displays might be different from what you see here. Typographic Conventions • In this book, text appearing in this font generally is text that is part of a graphical user interface. This includes text in labels, names of buttons and menus, and Web page addresses that you type into a Web browser. • Text appearing in this font generally is text that is part of a command-line interface. This includes prompts, user input, and responses. This font also is used to show the content of some communication protocols, such as headers, commands, and data between a client and a server. • In both cases, text that appears in italics like this or like this represents text that you should replace with text specific to your deployment. For example, the URL https:IlproxylPaddr.8082 appears often in this book. In this example, the text proxylPaddr should be replaced with the actual four-octet numeric IP address of your ProxySG. BlueTouch Training Services — BCCPA Course v3.5.1 2 Chapter 1: Blue Coat Product Family In a connected world, the network is increasingly becoming a platform for collaboration bringing people together to share ideas, speed decision-making, and enhance competitiveness. Collaborative applications such as teleconferencing, unified communications, and social media are being deployed at an increasing rate. An increasingly capable wide area network combines with a host of regulatory mandates to drive infrastructure and data center consolidation, enabling enterprises to gain greater efficiencies, contain costs, and enhance agility. The key trends driving business today — centralization, mobilization, and globalization — often make it difficult, if not downright impossible, to support on-demand application delivery. IT initiatives such as server consolidation and voice, video, and data convergence can disrupt network service. Your mobile applications and devices can be compromised by security breaches and data theft. And global IT infrastructures often harbor data silos that are difficult to penetrate and manage, obscuring the view of your IT resources. Maintaining a sustainable competitive advantage in a rapidly changing business environment requires new levels of responsiveness. Access to information where, when, and how it is needed is critical to success. In today’s market, information is the currency of business. Delivering a superior user experience across corporate, branch, and remote locations depends on having: • The visibility to control what is running on the network. • The ability to accelerate business applications and meter recreational traffic. • The ability to do so in a safe and secure manner. Application Delivery Networks (ADNs) are emerging as an essential requirement in addressing these challenges. Blue Coat products provide an ADN infrastructure designed to optimize and secure the flow of information to any user, on any network, anywhere. After studying this chapter, you will understand: • The concepts of the Application Delivery Network. • How Blue Coat’s product family implements the ADN. • Basic features of each member of the Blue Coat product family. 3 BlueTouch Training Services — BCCPA Course v3.5.1 Application Delivery Network S Slide 1 —1: Application Delivery Network Implementing the Application Delivery Network answers the demand for greater application mobility and security in a changing global business environment. By combining three core capabilities — application performance monitoring (visibility), WAN optimization (acceleration), and Secure Web Gateway technologies (security) — the ADN helps you: • See applications and users and how they behave on the network. • Troubleshoot performance issues. — • Accelerate mission-critical applications, streaming video, SSL, and other enterprise applications. • Secure against malware, data leaks, and performance degradation. • Enable a highly efficient and productive end-to-end user experience anytime, anywhere. Visibility ¶ ii Blue Coat’s ADN solutions provide the ability to identify and classify applications and users across the network. You can discover all application traffic, monitor the user experience, troubleshoot performance issues and resolve problems before they impact the user experience. You can: — • Automatically discover more than 600 applications. • Identify peer-to-peer (P2P), recreational, and streaming applications over any port. • Subclassify complex applications such as SAP, Oracle, Citrix, Web, CIFS, MAPI, and DCOM. • Discover URLs and external sites within HTTP. • Identify problem hosts, servers, and applications. 1 4 [[i Chapter 1: Blue Coat Product Family Acceleration Blue Coat helps you accelerate business-critical applications, including internal, external, and real-time applications to any user, anywhere — all while ensuring a headquarters work experience, wherever your users are located. Acceleration technologies include: • Object and byte caching. • Compression and basic quality-of-service capabilities. • External Web and SSL acceleration. • Protocol acceleration for TCP, CIFS/NFS, MAPI, HTTP, and more. • Advanced Web policy and bandwidth management. • Advanced application ID technology. Security Blue Coat secures your Internet gateway to help protect users from malicious content and applications. Security capabilities include: • Anti-virus and maiware scanning. • Comprehensive data loss prevention. • URL and Web content filtering. • A centrally managed distributed gateway. • Granular policy management across more than 500 variables, including user, group, application, source, content types, and transaction. • Logging, statistics, and SNMP support. 5 BIueTouchTrairNng Services — BCCPA Course v3.5.1 Blue Coat Products BlueQCoat 3 P Slide 1 —2: Blue Coat products Blue Coat products provide total visibility and control over user and application performance — and fast, secure delivery of the critical applications that fuel business productivity.

It is shut up in libraries, and should a stray copy come abroad, it is rarely to be obtained by him who seeks for it. This is not so much because the work is sought for by many, and largely known; for the principles it teaches are almost as much in advance of the present times as they were in the days of the 'sainted George Herbert' and Nicholas Ferrar, who first published it in English.

  • Chapter 12 Simple Graphics Programming
    140 Chapter 12 Simple Graphics Programming Graphical applications are more appealing to users than text-based programs. When designed properly, graphical applications are more intuitive to use. From the developers perspective, graphical programs provide an ideal oppor- tunity to apply object-oriented programming concepts. Java provides a wealth of classes for building graphical user interfaces (GUIs). Because of the power and flexibility provided by these classes experienced developers can use them to create sophisticated graphical applications. On the other hand, also because of the power and flexibility of these graphical classes, writing even a simple graphics program can be daunting for those new to programming— especially those new to graphics programming. For those experienced in building GUIs, Java simplifies the process of developing good GUIs. Good GUIs are necessarily complex. Consider just two issues: • Graphical objects must be positioned in an attractive manner even when windows are resized or the application must run on both a PC (larger screen) and a PDA or cell phone (much smaller screen). Java graphical classes simplify the programmer’s job of laying out of screen elements within an application. • The user typically can provide input in several different ways: via mouse clicks, menu, dialog boxes, and keystrokes. The program often must be able to respond to input at any time, not at some predetermined place in the program’s execution. For example, when a statement calling nextInt() on a Scanner object (§ 8.3) is executed, the program halts and waits for the user’s input; however, in a graphical program the user may select any menu item at any time.

For example, there is Marc Ruef with whom I touched base on the initial idea for this thesis during a lunch discussion. We share a similar experience on security testing and found out that we were both not fully satisfied with the way the results are provided to the client. Another thank you goes to Jan Monsch, the creator of DAVIX. He was able to draw my attention to the subject of visualization when we worked together as security analysts. Quite a few items of his personal library moved to my place for the duration of this thesis. I would also like to thank William Rothwell for becoming my project supervisor and for his ongoing support. He received the first status report in October last year and has been providing valuable feedback since. Few people have read the project report as many times as he did.

Skinner ABSTRACT. A uniformly valid asymptotic expansion for the solution to a class of singularly perturbed Volterra integral equations displaying exponential boundary layer behavior is established. Certain quasilinear ordinary differential equations are a noted special case, and a model for population growth with attrition is briefly discussed. 1.

We are interested in the asymptotic behavior as e —> 0+ of the solution to the Volterra integral equation €y(x,e)+ / k(x,t,e,y(t,e))dt = f(x,e). (1.1) Jo The assumption /(0, 0) = 0, which implies y(0, e) = /e(0, 0) + O(e), is nontrivial unless (1.1) is linear. If kyy(x,t,e,y) = 0, we can get /(0,0) = 0 by changing the unknown (if necessary) to ey(x^e).
