| curl ssl certificate problem: Secure Messaging Scenarios with WebSphere MQ T.Rob Wyatt, Glenn Baddeley, Neil Casey, Long Nguyen, Jørgen H. Pedersen, Morten Sætra, IBM Redbooks, 2013-04-02 The differences between well-designed security and poorly designed security are not always readily apparent. Poorly designed systems give the appearance of being secure but can over-authorize users or allow access to non-users in subtle ways. The problem is that poorly designed security gives a false sense of confidence. In some ways, it is better to knowingly have no security than to have inadequate security believing it to be stronger than it actually is. But how do you tell the difference? Although it is not rocket science, designing and implementing strong security requires strong foundational skills, some examples to build on, and the capacity to devise new solutions in response to novel challenges. This IBM® Redbooks® publication addresses itself to the first two of these requirements. This book is intended primarily for security specialists and IBM WebSphere® MQ administrators that are responsible for securing WebSphere MQ networks but other stakeholders should find the information useful as well. Chapters 1 through 6 provide a foundational background for WebSphere MQ security. These chapters take a holistic approach positioning WebSphere MQ in the context of a larger system of security controls including those of adjacent platforms' technologies as well as human processes. This approach seeks to eliminate the simplistic model of security as an island, replacing it instead with the model of security as an interconnected and living system. The intended audience for these chapters includes all stakeholders in the messaging system from architects and designers to developers and operations. Chapters 7 and 8 provide technical background to assist in preparing and configuring the scenarios and chapters 9 through 14 are the scenarios themselves. These chapters provide fully realized example configurations. One of the requirements for any scenario to be included was that it must first be successfully implemented in the team's lab environment. In addition, the advice provided is the cumulative result of years of participation in the online community by the authors and reflect real-world practices adapted for the latest security features in WebSphere MQ V7.1 and WebSphere MQ V7.5. Although these chapters are written with WebSphere MQ administrators in mind, developers, project leaders, operations staff, and architects are all stakeholders who will find the configurations and topologies described here useful. The third requirement mentioned in the opening paragraph was the capacity to devise new solutions in response to novel challenges. The only constant in the security field is that the technology is always changing. Although this book provides some configurations in a checklist format, these should be considered a snapshot at a point in time. It will be up to you as the security designer and implementor to stay current with security news for the products you work with and integrate fixes, patches, or new solutions as the state of the art evolves. |

Over 150 pages filled with photos of kettlebell exercise, basic descriptions, and links to bonus videos. Kettlebell training is a form of resistance training with the kettlebell. This encyclopedia and its volumes cover all kettlebell exercises with photos, descriptions, and some having step-by-step instructions. The information in this book will allow you to pick kettlebell exercises and create your own kettlebell workout and/or verify that you’re doing the exercises you’re already doing, correctly. This volume covers kettlebells carries, cleans, curl, and getups. Each subject has just enough information to keep it basic and understandable. Kettlebell Carry Support and move a kettlebell from one place to another. The support can be provided in the form of overhead, racked, hanging, or a mixture of aforementioned methods. Kettlebell Clean A kettlebell clean is an explosive lower-body powered movement that lifts a kettlebell from a lower position to a higher position which is called racking position. The clean can be performed from the ground (dead), hanging position, or a during a ballistic movement like the swing. Anytime a clean is performed with a swing, then that swing can be either one of the following movements, hip hinge swing, pendulum swing, or squat swing. Kettlebell Curl Curl refers to the curling motion which in exercise can be performed with the elbow or knee joint, i.e. Biceps Curls or Leg Curls. Think flexion and extension of the elbow joint, or decreasing and increasing the angle of the elbow joint. When it comes to kettlebell training the common curling exercise used is the biceps curl, although technically speaking the leg curl could be performed laying down and the foot through the window of the kettlebell. Kettlebell Get-up To get up into a fully erect position any way possible from laying flat on the floor. This can be done with 1 or 2 kettlebells positioned overhead or racked. |
| curl ssl certificate problem: RESTful Web Services Leonard Richardson, Sam Ruby, 2008-12-17 Every developer working with the Web needs to read this book. -- David Heinemeier Hansson, creator of the Rails framework RESTful Web Services finally provides a practical roadmap for constructing services that embrace the Web, instead of trying to route around it. -- Adam Trachtenberg, PHP author and EBay Web Services Evangelist You've built web sites that can be used by humans. But can you also build web sites that are usable by machines? That's where the future lies, and that's what RESTful Web Services shows you how to do. The World Wide Web is the most popular distributed application in history, and Web services and mashups have turned it into a powerful distributed computing platform. But today's web service technologies have lost sight of the simplicity that made the Web successful. They don't work like the Web, and they're missing out on its advantages. This book puts the Web back into web services. It shows how you can connect to the programmable web with the technologies you already use every day. The key is REST, the architectural style that drives the Web. This book: Emphasizes the power of basic Web technologies -- the HTTP application protocol, the URI naming standard, and the XML markup language Introduces the Resource-Oriented Architecture (ROA), a common-sense set of rules for designing RESTful web services Shows how a RESTful design is simpler, more versatile, and more scalable than a design based on Remote Procedure Calls (RPC) Includes real-world examples of RESTful web services, like Amazon's Simple Storage Service and the Atom Publishing Protocol Discusses web service clients for popular programming languages Shows how to implement RESTful services in three popular frameworks -- Ruby on Rails, Restlet (for Java), and Django (for Python) Focuses on practical issues: how to design and implement RESTful web services and clients This is the first book that applies the REST design philosophy to real web services. It sets down the best practices you need to make your design a success, and the techniques you need to turn your design into working code. You can harness the power of the Web for programmable applications: you just have to work with the Web instead of against it. This book shows you how. |

Over 150 pages filled with photos of kettlebell exercise, basic descriptions, and links to bonus videos. Kettlebell training is a form of resistance training with the kettlebell. This encyclopedia and its volumes cover all kettlebell exercises with photos, descriptions, and some having step-by-step instructions. The information in this book will allow you to pick kettlebell exercises and create your own kettlebell workout and/or verify that you’re doing the exercises you’re already doing, correctly. This volume covers kettlebells presses, push-ups, rows, and snatches. Each subject has just enough information to keep it basic and understandable. Kettlebell Press The press and push movement are very similar when you look at the arms, they’re always extending, whether overhead or above the chest (laying down), however, there is a clear difference between the two. With the press, you exert physical force on the kettlebell to move it away from you rather than to move yourself away from it (push). Kettlebell Push-up Similar to the press, you exert physical force on the kettlebell, but in this case, it’s in order to move yourself away from it. A push-up done on the floor would be pushing yourself away from the floor. If you take the same push-up position and turn it around—laying flat—and perform the same movement it becomes as press as you’re moving the object away from yourself. Kettlebell Row When looking at the movement in boat rowing it’s always a pull and push off the oar. In the context of kettlebell training, a row is always a pull as gravity replaces the push. A row has to be performed in such a way that you’re acting directly against gravity. The focus of the kettlebell row are the posterior muscles of the upper back. Kettlebell Snatch A snatch is a movement in which the kettlebell rapidly raised from a lower position—always below the hips—to above the head in one continuous smooth explosive movement. An example of a few common start positions are dead, hanging, and swinging. |

| curl ssl certificate problem: Implementing IBM CICS JSON Web Services for Mobile Applications Rufus Credle, Andy Armstrong, Chris Atkinson, Russell Bonner, Geoff Pirie, Inderpal Singh, Nigel Williams, Matthew Wilson, Mark Woolley, IBM Redbooks, 2013-11-27 This IBM® Redbooks® publication provides information about how you can connect mobile devices to IBM Customer Information Control System (CICS®) Transaction Server (CICS TS), using existing enterprise services already hosted on CICS, or to develop new services supporting new lines of business. This book describes the steps to develop, configure, and deploy a mobile application that connects either directly to CICS TS, or to CICS via IBM Worklight® Server. It also describes the advantages that your organization can realize by using Worklight Server with CICS. In addition, this Redbooks publication provides a broad understanding of the new CICS architecture that enables you to make new and existing mainframe applications available as web services using JavaScript Object Notation (JSON), and provides support for the transformation between JSON and application data. While doing so, we provide information about each resource definition, and its role when CICS handles or makes a request. We also describe how to move your CICS applications, and business, into the mobile space, and how to prepare your CICS environment for the following scenarios: Taking an existing CICS application and exposing it as a JSON web service Creating a new CICS application, based on a JSON schema Using CICS as a JSON client This Redbooks publication provides information about the installation and configuration steps for both Worklight Studio and Worklight Server. Worklight Studio is the Eclipse interface that a developer uses to implement a Worklight native or hybrid mobile application, and can be installed into an Eclipse instance. Worklight Server is where components developed for the server side (written in Worklight Studio), such as adapters and custom server-side authentication logic, run. CICS applications and their associated data constitute some of the most valuable assets owned by an enterprise. Therefore, the protection of these assets is an essential part of any CICS mobile project. This Redbooks publication, after a review of the main mobile security challenges, outlines the options for securing CICS JSON web services, and reviews how products, such as Worklight and IBM DataPower®, can help. It then shows examples of security configurations in CICS and Worklight. |
