Summary:Computer access control has always been a challenge. Left to themselves, computers tend to treat one user no differently than another. Computers use authentication to confidently associate an identity with a person.
Authentication: From Passwords to Public Keys gives readers a clear understanding of what an organization needs to reliably identify its users and how the different techniques for verifying identity are executed.
Authentication is one of the basic building blocks of security. To allow a computer system to distinguish between legitimate users and others, most sites give passwords to authorized users. Unfortunately, just as car thieves pick locks, computer hackers have found ways to circumvent many password systems. But today, organizations have a broad range of alternatives to passwords, and a variety of ways to make passwords safer. A well-designed authentication system allows users to prove their identities and gain access to the network without threatening the safety of the organization.
The first of its kind, Authentication describes the entire range of authentication methods used today. It examines situations in which certain techniques fail and points out ways to strengthen them. Network professionals, designers, developers, administrators, planners, and managers will discover the right authentication strategy to achieve results. Through diagrams and examples, the author thoroughly explains the technical concepts behind authentication, focusing on existing, off-the-shelf solutions to security problems.
Authentication: From Passwords to Public Keys highlights real products and solutions, not novel technology that seems promising. If you are a network professional searching for the how and why of computer authentication, then this is the book that will help you prevent unauthorized access on your network.
