Book Description
Previous information security references do not address the gulf between general security awareness and the specific technical steps that need to be taken to protect information assets. Surviving Security: How to Integrate People, Process, and Technology, Second Edition fills this void by explaining security through a holistic approach that considers both the overall security infrastructure and the roles of each individual component. This book provides a blueprint for creating and executing sound security policy. The author examines the costs and complications involved, covering security measures such as encryption, authentication, firewalls, intrusion detection, remote access, host security, server security, and more. After reading this book, you will know how to make educated security decisions that provide airtight, reliable solutions. About the Author Amanda Andress, CISSP, SSCP, CPA, CISA is Founder and President of ArcSec Technologies, a firm which focuses on security product reviews and consulting. Prior to that she was Director of Security for Privada, Inc., a privacy company in San Jose, California. She built extensive security auditing and IS control experience working at Exxon and Big 5 firms Deloitte & Touche and Ernst & Young.

Book Description
El arma más poderosa que posee el ser humano es la información, ya que le permite conocer, predecir, manipular, sobrevivir y, en definitiva, estar un paso por delante con respecto a quien no dispone de ella. Por esta razón, uno de sus principales objetivos no sólo es llegar a conocer algo, sino tener también la capacidad de salvaguardarlo de forma segura, es decir, que únicamente permanezca accesible para aquellas personas autorizadas. Una de las posibles soluciones pasa por encriptar la información antes de ser transmitida, empleando para ello Redes Privadas Virtuales. El término de Red Privada Virtual (VPN), en inglés Virtual Private Network, hace referencia a un canal de comunicación privado e implementado sobre una infraestructura de acceso público. Dos extremos van a acordar en base a un protocolo y a una serie de políticas de seguridad previamente establecidas, las características de un túnel sobre el cual enviar los datos de manera confidencial. Esta información será cifrada antes de ser inyectada por el enlace, de ahí viene el concepto de “privada”. La condición de “virtual” se corresponde al hecho de que cuando la VPN esté establecida, se tendrá un contacto aparente pero no real entre los participantes de la misma. El libro está estructurado en siete capítulos: se ha dedicado un capítulo entero a la introducción de los conceptos fundamentales de las VPNs; otro a presentar de forma genérica un breve resumen de la arquitectura TCP/IP, pilar fundamental de las redes de comunicación. A continuación tenemos un capítulo destinado completamente a los sistemas criptográficos modernos, ya que ésta será la base principal sobre la que se sustenten las VPNs. Y por último, se ha dedicado un capítulo por cada clase de VPN tratada: IPSec, PPTP, L2TP/IPSec y SSL. El planteamiento de exposición para los capítulos correspondientes a las VPNs será común para todos los protocolos. En primer lugar, se presentarán una serie de conceptos teóricos; posteriormente se estudiarán un grupo de herramientas que permitirán poner en práctica dichas ideas, y a partir de todo ello, se desarrollarán un conjunto de casos prácticos que facilitarán al lector el asentamiento de los conocimientos adquiridos. A su vez, también se incluirá una sección dedicada íntegramente a la recopilación y tratamiento de los mensajes de error.

Book Description
VPNs enable any enterprise to utilize the Internet as its own secure private network. In this book, two leading VPN implementers offer a start-to-finish, hands-on guide to constructing and operating secure VPNs. Going far beyond the theory found in most books, Ruixi Yuan and Tim Strayer present best practices for every aspect of VPN deployment, including tunneling, IPsec, authentication, public key infrastructure, and network/service management. Strayer and Yuan begin with a detailed overview of the fundamental concepts and architectures associated with enterprise VPNs, including site-to-site VPNs, remote access VPNs, and extranets. They compare all options for establishing VPN tunnels across the Internet, including PPTP, L2F, and L2TP. Next, they present in-depth coverage of implementing IPsec; establishing two-party or trusted third-party authentication; building a robust public key infrastructure; and managing access control. The book includes expert coverage of VPN gateway configuration, provisioning, and management; Windows and other VPN clients; and network/service management, including SLAs and network operations centers. Finally, the authors preview the future of VPNs, showing how they may be enhanced to provide greater quality of service and network intelligence. For all networking and IT professionals, security specialists, consultants, vendors, and service providers responsible for building or operating VPNs.

Book Description
Virtual private networks (VPNs) based on the Internet instead of the traditional leased lines offer organizations of all sizes the promise of a low-cost, secure electronic network. However, using the Internet to carry sensitive information can present serious privacy and security problems. By explaining how VPNs actually work, networking expert Jon Snader shows software engineers and network administrators how to use tunneling, authentication, and encryption to create safe, effective VPNs for any environment. Using an example-driven approach, VPNs Illustrated explores how tunnels and VPNs function by observing their behavior "on the wire." By learning to read and interpret various network traces, such as those produced by tcpdump, readers will be able to better understand and troubleshoot VPN and network behavior. Specific topics covered include: Block and stream symmetric ciphers, such as AES and RC4; and asymmetric ciphers, such as RSA and EIGamal Message authentication codes, including HMACs Tunneling technologies based on gtunnel SSL protocol for building network-to-network VPNs SSH protocols as drop-in replacements for telnet, ftp, and the BSD r-commands Lightweight VPNs, including VTun, CIPE, tinc, and OpenVPN IPsec, including its Authentication Header (AH) protocol, Encapsulating Security Payload (ESP), and IKE (the key management protocol) Packed with details, the text can be used as a handbook describing the functions of the protocols and the message formats that they use. Source code is available for download, and an appendix covers publicly available software that can be used to build tunnels and analyze traffic flow. VPNs Illustrated gives you the knowledge of tunneling and VPN technology you need to understand existing VPN implementations and successfully create your own.
