Download or read book Digital Success A Holistic Approach to Digital Transformation for Enterprises and Manufacturers written by Alasdair Gilchrist and published by Alasdair Gilchrist. This book was released on 2018-11-04 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is Digital Transformation, why is it so important and why do so many transformation projects fail? More importantly, what can we do to make our transformation initiative succeed? These are a few of the profound questions that we seek to answer in this book. The anomaly between the number of digital transformation being undertaken and the high failure rate may be due to not enough transformation initiatives taking a holistic approach that encompasses people, culture, organisations, processes, business strategy and objectives into the overall mix instead they are focusing largely on the technology. Therefore in this book we contemplate a holistic approach to digital transformation across the entire spectrum of the business from the perspective of an enterprise or manufacturer. Hence we start with people, culture and the need for agile business development when transforming processes, products and services or business models. We examine the how and why we align and tightly couple business objectives to transformation initiatives. Importantly, we examine the need for company-wide collaboration and integration of data, knowledge, processes and systems and the huge benefits initiatives such as data-democratization can deliver. Then we delve deeper into the specific drivers for successful transformation across a very broad range of business functions from the perspective of IT and Operations, Finance, HR, Sales & Marketing, Manufacturing, Inventory, Supply chain and Post-sales service. We also examine how technology and processes such as the IoT and advanced data analysis have brought about Industry 4.0 and the Smart Factory not through technology upgrades and point solutions but through a holistic approach to digital transformation. A holistic approach to digital transformation, places people, culture, knowledge, capabilities, and decision-making as the pillars supporting the overall organisation's business strategy, objectives and mission values that are built upon a foundation of technology and processes. Successful digital transformation initiatives do not lose their focus on the overarching business strategy and company objectives being the goal, it's not about technology it is about creating new business value at the strategic level. And in this book we will show you how to do it.What is Digital Transformation, why is it so important and why do so many transformation projects fail?

Download or read book Network Security with OpenSSL written by John Viega and published by "O'Reilly Media, Inc.". This book was released on 2002-06-17 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
