Technological Issues (continued)


Information submitted on the Internet can be used in
computer crime


The best way to protect data is to control access of
the data, most often through passwords


Other security measures include using ID cards,
firewalls, antivirus software, selective hiring
practices, and data backups


Biometric security measures

examine a
fingerprint, a voice pattern, or the iris or retina of the
eye and compare them against employee records
