Administrators can use a number of methods to keep unwanted users off their networks, including:
- Filtering technologies, such as media access controls, can weed out devices that are foreign to an organization.
- Passwords and PINs can help verify only the people with authorization to use a network are allowed access.
- Cards and other devices distributed only to employees authorized to access a network can also help ensure only desired users gain access.
- Biometric identifiers, such as fingerprint readers, iris scanners or voice recognition technologies, confine network access to certain users and can't be shared with others.
