Network security concepts Network security starts with authenticating‚ commonly with a username and a password. Since this requires just one detail authenticating the user name —i.e. the password— this is sometimes termed one-factor authentication. With two-factor authentication‚ something the user ’has’ is also used (e.g. a security token or ’dongle’‚ an ATM card‚ or a mobile phone); and with three-factor authentication‚ something the user ’is’ is also used (e.g. a fingerprint or retinal scan)
