Virtual Private Networks by Ruixi Yuan,W. Timothy Strayer Pdf

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.

Virtual Private Networks For Dummies by Mark S. Merkow Pdf

Let’s face it: the information age makes dummies of us all at some point. One thing we can say for sure, though, about things related to the Internet is that their best strengths are often also their worst weaknesses. This goes for virtual private networks (VPNs). They may reach a wide base of customers – but can also be vulnerable to viruses, hackers, spoofers, and other shady online characters and entities. VPNs may allow for super-efficient communication between customer and company – but they rely on information which, if compromised, can cause huge losses. The Internet is still a frontier – sometimes so wide open it leaves us bewildered – and, like any frontier, the risks go hand in hand with potentially huge rewards. Virtual Private Networks for Dummies offers you a no-nonsense, practical guide to evaluating your company’s need for a VPN, understanding what it takes to implement one, and undertaking the challenging quest to set it up, make it work, and keep it safe. Whether you’re the resident expert leading the project team, or you just want to learn what makes e-commerce tick, this detailed, from-the-ground-up guide will soon have you comfortably conceptualizing: Security goals and strategies The evolution of VPNs Privacy in VPNs Extranets Remote-Access VPNs Funding Custom network solutions design Testing VPNs And more With new products and technologies offering supposedly revolutionary solutions to IT departments every day, this book focuses on the real world – you know, the one full of obstacles, mishaps, threats, delays, and errors – and gives you the background knowledge to make decisions for yourself about your VPN needs. Written with a dash of humor, Virtual Private Networks for Dummies contains both technical detail (standards, protocols, etc.) and more general concepts (such as conducting cost-benefit analyses). This clear, authoritative guide will have you securely and cost-effectively networking over the Internet in no time.

It helps the reader build a strong foundation of information, allowing them to move forward from the book with a larger knowledge base. Security is a constantly growing concern that everyone must deal with. Whether it’s an average computer user or a highly skilled computer user, they are always confronted with different security risks. These risks range in danger and should always be dealt with accordingly. Unfortunately, not everyone is aware of the dangers or how to prevent them and this is where most of the issues arise in information technology (IT). When computer users do not take security into account many issues can arise from that like system compromises or loss of data and information. This is an obvious issue that is present with all computer users. This book is intended to educate the average and experienced user of what kinds of different security practices and standards exist. It will also cover how to manage security software and updates in order to be as protected as possible from all of the threats that they face.

Building Internet Firewalls by Elizabeth D. Zwicky,Simon Cooper,D. Brent Chapman Pdf

In the five years since the first edition of this classic book was published, Internet use has exploded. The commercial world has rushed headlong into doing business on the Web, often without integrating sound security technologies and policies into their products and methods. The security risks--and the need to protect both business and personal data--have never been greater. We've updated Building Internet Firewalls to address these newer risks. What kinds of security threats does the Internet pose? Some, like password attacks and the exploiting of known security holes, have been around since the early days of networking. And others, like the distributed denial of service attacks that crippled Yahoo, E-Bay, and other major e-commerce sites in early 2000, are in current headlines. Firewalls, critical components of today's computer networks, effectively protect a system from most Internet security threats. They keep damage on one part of the network--such as eavesdropping, a worm program, or file damage--from spreading to the rest of the network. Without firewalls, network security problems can rage out of control, dragging more and more systems down. Like the bestselling and highly respected first edition, Building Internet Firewalls, 2nd Edition, is a practical and detailed step-by-step guide to designing and installing firewalls and configuring Internet services to work with a firewall. Much expanded to include Linux and Windows coverage, the second edition describes: Firewall technologies: packet filtering, proxying, network address translation, virtual private networks Architectures such as screening routers, dual-homed hosts, screened hosts, screened subnets, perimeter networks, internal firewalls Issues involved in a variety of new Internet services and protocols through a firewall Email and News Web services and scripting languages (e.g., HTTP, Java, JavaScript, ActiveX, RealAudio, RealVideo) File transfer and sharing services such as NFS, Samba Remote access services such as Telnet, the BSD "r" commands, SSH, BackOrifice 2000 Real-time conferencing services such as ICQ and talk Naming and directory services (e.g., DNS, NetBT, the Windows Browser) Authentication and auditing services (e.g., PAM, Kerberos, RADIUS); Administrative services (e.g., syslog, SNMP, SMS, RIP and other routing protocols, and ping and other network diagnostics) Intermediary protocols (e.g., RPC, SMB, CORBA, IIOP) Database protocols (e.g., ODBC, JDBC, and protocols for Oracle, Sybase, and Microsoft SQL Server) The book's complete list of resources includes the location of many publicly available firewall construction tools.

Virtual Private Networks by Charlie Scott,Paul Wolfe,Mike Erwin Pdf

Historically, only large companies could afford secure networks, which they created from expensive leased lines. Smaller folks had to make do with the relatively untrusted Internet. Nowadays, even large companies have to go outside their private nets, because so many people telecommute or log in while they're on the road. How do you provide a low-cost, secure electronic network for your organization?The solution is a virtual private network: a collection of technologies that creates secure connections or "tunnels" over regular Internet lines--connections that can be easily used by anybody logging in from anywhere. A number of products now exist to help you develop that solution.This book tells you how to plan and build a VPN. It starts with general concerns like costs, configuration, and how a VPN fits in with other networking technologies like firewalls. It continues with detailed descriptions of how to install and use VPN technologies that are available for Windows NT and Unix, such as PPTP and L2TP, Altavista Tunnel, Cisco PIX, and the secure shell (SSH).New features in the second edition include SSH, which is a popular VPN solution for Unix systems, and an expanded description of the IPSec standard, for which several vendors have announced support.Topics include: How the VPN compares to other available networking technologies Introduction to encryption, firewalls, the IPSec standard, and other technologies that let VPNs work Point to Point Tunneling Protocol (PPTP) and L2TP The Altavista Tunnel The Cisco PIX Firewall Secure Shell (SSH) Maintenance and troubleshooting
