What Is Two-Factor Authentication?

Two-factor authentication is a security solution that enhances and strengthens security by

implementing multiple factors of the authentication process that challenge and confirm the

users’ identities before they can gain access to the network. There are several factors that

are used to validate the users to make sure that you are who you say you are. These factors

are:

• Something you know—for examp

le, your password or your PIN.

• Something you ha

ve—for example, a token with generated passcode that is 6 to 8 digits

in length.

• Something you are

—for example, biometrics such as fingerprints or retinal prints.

This appendix focuses on and discusses only the first two fa

ctors, something you know and

something you have. This security method can be viewed as a two-tiered authentication

approach because it typically relies on what you know and what you have. A common

example of two-factor authentication is a bank (ATM) card that has been issued by a bank

institute:

• T

he PIN to access your account is something you know.

• T

he ATM card is something you have.

You need to have both of these factors to gain access to your bank account. Similar to the

way A

TM cards work, access to the corporate networks and data can also be strengthened

using a combination of multiple factors such as a PIN and a token (hardware or software) to

validate the users and reduce the incidence of online identity theft.

NETGEAR Two-Factor Authentication Solutions

NETGEAR has implemented 2 two-factor authentication solutions from WiKID. WiKID is the

software-based token solution. So instead of using only Windows Active Directory or LDAP

as the authentication server, administrators now have the option to use WiKID to perform

two-factor authentication on NETGEAR SSL and VPN firewall products.

The WiKID solution is based on a request-response architecture where a one-time passcode

(OTP), which is time-synchronized with the authentication server, is generated and sent to

the user after the validity of a user credential has been confirmed by the server.

The request-response architecture is capable of self-service initialization by end users,

dramatically reducing implementation and maintenance costs.

Here is an example of how WiKID works:

 To use WiKID (for end users):

1. L

aunch the WiKID token software, enter the PIN that has been provided (something the

user knows), and then click Continue to receive the OTP from the WiKID authentication

server:

1 2 ... 396 397 398 399 400 401 402 403 404 405 406 ... 424 425
