Fook Seng noted that at present there are three kinds of authentication
mechanisms available in the market, namely, one-factor, two-factor as well as
three-factor authentication. Their performance varies in terms of level of
security, as well as the deployment cost and complexity involved.
Today most corporate networks only require static identity credentials for access to facilities, networks and sensitive information. The enormous increase in computing power makes this type of one-factor authentication extremely risky and it is quickly becoming obsolete.
At the other end of the authentication continuum, are three-factor solutions that take advantage of biometrics. While these solutions offer an exceptionally high level of security, their high outlay and complexity of deployment generally makes them viable only for large-scale government projects such as border control and citizen travel documentation. In light of this, many companies opt for two-factor authentication – a more secure option than one-factor solutions, but not as expensive or complex as three-factor ones.
