TLS Cryptography In-Depth. Explore the intricacies of modern cryptography and the inner workings of TLS

Dr. Paul Duplys, Dr. Roland Schmitz

TLS is the most widely used cryptographic protocol today, enabling e-commerce, online banking, and secure online communication. Written by Dr. Paul Duplys, Security, Privacy & Safety Research Lead at Bosch, and Dr. Roland Schmitz, Internet Security Professor at Stuttgart Media University, this book will help you gain a deep understanding of how and why TLS works, how past attacks on TLS were possible, and how vulnerabilities that enabled them were addressed in the latest TLS version 1.3. By exploring the inner workings of TLS, you’ll be able to configure it and use it more securely.Starting with the basic concepts, you’ll be led step by step through the world of modern cryptography, guided by the TLS protocol. As you advance, you’ll be learning about the necessary mathematical concepts from scratch. Topics such as public-key cryptography based on elliptic curves will be explained with a view on real-world applications in TLS. With easy-to-understand concepts, you’ll find out how secret keys are generated and exchanged in TLS, and how they are used to creating a secure channel between a client and a server.By the end of this book, you’ll have the knowledge to configure TLS servers securely. Moreover, you’ll have gained a deep knowledge of the cryptographic primitives that make up TLS.

Untangle Network Security. Secure your network against threats and vulnerabilities using the unparalleled Untangle NGFW

Abd El Monem A Mohamed El Bawab

VMware vCloud Security. If you're familiar with Vmware vCloud, this is the book you need to take your security capabilities to the ultimate level. With a comprehensive, problem-solving approach it will help you create a fully protected private cloud

Prasenjit Sarkar, Prasenjit Sarkar

Security is a major concern, in particular now that everything is moving to the cloud. A private cloud is a cloud computing platform built on your own hardware and software. The alternative is to deploy the services you need on a public cloud infrastructure provided by an external supplier such as Amazon Web Services, Rackspace Cloud, or HP Public Cloud. While a public cloud can afford greater flexibility, a private cloud gives you the advantage of greater control over the entire stack.VMware vCloud Security focuses on some critical security risks, such as the application level firewall and firewall zone, virus and malware attacks on cloud virtual machines, and data security compliance on any VMware vCloud-based private cloud. Security administrators sometimes deploy its components incorrectly, or sometimes cannot see the broader picture and where the vCloud security products fit in. This book is focused on solving those problems using VMware vCloud and the vCloud Networking and Security product suite, which includes vCloud Networking and Security App, vShield Endpoint, and vCloud Networking and Security Data Security.Ensuring the security and compliance of any applications, especially those that are business critical, is a crucial step in your journey to the cloud. You will be introduced to security roles in VMware vCloud Director, integration of LDAP Servers with vCloud, and security hardening of vCloud Director. We'll then walk through a hypervisor-based firewall that protects applications in the virtual datacenter from network-based attacks. We'll create access control policies based on logical constructs such as VMware vCenter Server containers and VMware vCloud Networking and Security security groups but not just physical constructs, such as IP addresses. You'll learn about the architecture of EPSEC and how to implement it. Finally, we will understand how to define data security policies, run scans, and analyze results.

VMware View Security Essentials. The vital elements of securing your View environment are the subject of this user-friendly guide. From a theoretical overview to practical instructions, it's the ideal tutorial for beginners and an essential reference source for the more experienced

Daniel Langenhan

Most people associate security with network security and focus on firewalls and network monitoring. However, there is more to security than that. Security starts with the establishment of a stable environment, protecting this environment not only from intrusion, but also from malicious intent. It is about tracking the issue and recovering from it. These elements of security are what this book aims to address.VMware View Security Essentials addresses the topic of security in the corporate environment in a new way. It starts with the underlying virtual infrastructure and then delves into securing your base, your connection, and your client. This is not only a “how-to” book, but is also a book that explains the background and the insights of View security for the experienced professional's desktop virtualization.This book takes you through the four major View security areas. Each area deals with all the aspects of security and explains the background as well as laying out simple-to-follow recipes to implement a higher security standard.We start at the Virtualization base and work our way through the various View server types. We will then dive into the problems and issues of securing a connection before we address the security of the desktop itself. We conclude with a look into the backing up of our View installation and preparing for disaster recovery.
