Biometrics and Network Security Abstract Biometrics are a growing technology that will most likely be seen applied to network security in the near future. Three options are discussed in this paper; keystroke dynamics‚ fingerprinting‚ and iris scanning. Each option has its strengths and weaknesses but none of them are a standalone solution to access a network. Should any of these solutions be applied they would need to be combined with password or token security measures that are currently
