Firewall
|
A Security procedure that places a specially programmed computer system between an organization's Local area network (LAN) and the Internet.
It's a legal barrier that prevents both the transference of inside information and the performance of financial transactions between commercial and investment banks. Restrictions placed on collaborations between banks and brokerage firms under the Glass-Steagall Act of 1933, acted as a form of firewall.
This works similarly to fire wall software and hardware used in preventing or limiting outside access to a company's internal servers and networks.
The firewall computer prevents hackers from accessing the internal network. Unfortunately, it also prevents the organization's computer users from gaining direct access to the Internet. The access that the firewall provides is indirect and mediated by programs called proxy servers.
