Guide to IPsec VPNs: NiST SP 800-77

Release date: July 2019

IPsec is a framework of open standards for ensuring private communications over public networks. It has become the most common network layer security control, typically used to create a virtual private network (VPN). A VPN is a virtual network built on top of existing physical networks that can provide a secure communications mechanism for data and control information transmitted between networks. VPNs are used most often to protect communications carried over public networks such as the Internet.

A VPN can provide several types of data protection, including confidentiality, integrity, data origin authentication, replay protection and access control.

Why buy a book you can download for free? We print this so you don't have to

First you gotta find it and make sure it’s the latest version, not always easy. Then you gotta print it using a network printer you share with 100 other people – and its outta paper – and the toner is low (take out the toner cartridge, shake it, then put it back). If it’s just 10 pages, no problem, but if it’s a 250-page book, you will need to punch 3 holes in all those pages and put it in a 3-ring binder. Takes at least an hour. An engineer that’s paid $75 an hour has to do this himself (who has assistant’s anymore?).

If you are paid more than $10 an hour and use an ink jet printer, buying this book will save you money.

It’s much more cost-effective to just order the latest version from Amazon.com
