The network security field is continuing down the same route. The same methodologies are being used with the addition of biometric identification. Biometrics provides a better method of authentication than passwords. This might greatly reduce the unauthorized access of secure systems. New technology such as the smart card is surfacing in research on network security. The software aspect of network security is very dynamic. Constantly new firewalls and encryption schemes are being implemented. The research being performed assists in understanding current development and projecting the future developments of the field.
