Definition: A software application that allows only authorized users through and blocks all others.

What This Means: A firewall keeps a computer, and the data on it, secure from intruders. Firewalls may provide a first line of defense against unauthorized access to data and systems; however, an education agency must take additional steps to ensure that those users who pass through the firewall are allowed access only to authorized data as per FERPA and local policy. (See Proxy Server).
