Most applications these days are at least somewhat network aware, but how do you protect those applications against common network security threats? Many developers are turning to OpenSSL, an open source version of SSL/TLS, which is the most widely used protocol for secure network communications.The OpenSSL library is seeing widespread adoption for web sites that require cryptographic functions to protect a broad range of sensitive information, such as credit card numbers and other financial transactions. The library is the only free, full-featured SSL implementation for C and C++, and it can be used programmatically or from the command line to secure most TCP-based network protocols.Network Security with OpenSSL enables developers to use this protocol much more effectively. Traditionally, getting something simple done in OpenSSL could easily take weeks. This concise book gives you the guidance you need to avoid pitfalls, while allowing you to take advantage of the library?s advanced features. And, instead of bogging you down in the technical details of how SSL works under the hood, this book provides only the information that is necessary to use OpenSSL safely and effectively. In step-by-step fashion, the book details the challenges in securing network communications, and shows you how to use OpenSSL tools to best meet those challenges.As a system or network administrator, you will benefit from the thorough treatment of the OpenSSL command-line interface, as well as from step-by-step directions for obtaining certificates and setting up your own certification authority. As a developer, you will further benefit from the in-depth discussions and examples of how to use OpenSSL in your own programs. Although OpenSSL is written in C, information on how to use OpenSSL with Perl, Python and PHP is also included.OpenSSL may well answer your need to protect sensitive data. If that?s the case, Network Security with OpenSSL is the only guide available on the subject.

Just as regular communication between a parent and child is vital to growing a secure, healthy relationship, so is prayer steeped in God’s word necessary to foster a secure, healthy relationship with our heavenly father. But in a world that moves at breakneck speed, slowing down and taking the time to pray persistently and intimately often seems an overwhelming or futile task for most Christians. This prayer guide is the result of years of personal study on prayer in the life of Susannah Baker and in the lives of women she disciples. Through use of the acronym PRAY, she provides clear, simple, yet effective tools to use in Praising, Repenting, Asking, and Yielding in prayer on a daily basis. Each section guides you through how to personalize your prayers to give expression to the struggles and deep, personal desires of your heart so that no matter your circumstances, there is space to walk freely and securely with a good father who dearly loves His children.Also available: Audio and video downloads available at susannahbaker.com/biblestudies  Secure: The Thirty-One Day Prayer Journal available at  susannahbaker.com/biblestudies/secure

In a penetrating account of the evolution of British intelligence gathering in India, C. A. Bayly shows how networks of Indian spies, runners and political secretaries were recruited by the British to secure information about their subjects. He also examines the social and intellectual origins of these informants, and considers how the colonial authorities interpreted and often misinterpreted the information they supplied. As Professor Bayly demonstrates, it was such misunderstandings which ultimately contributed to the failure of the British to anticipate the mutinies of 1857. He argues, however, that, even before this, India's complex systems of communication were challenging the political and intellectual dominance of the European rulers.
