Firewalls are the only means of protecting your network from an external threat. A firewall is your gateway to, and protection from, the Internet. Selecting a firewall is an important decision. Using an inadequate or problematic firewall is an invitation to disaster. Itek Systems is trained with the best security and firewall manufacturers today.

To further enhance the security of your network, Itek Systems can manage and monitor your firewall, assuring you the highest level of security, at a reasonable cost.

Firewall Requirements

To lock out intruders, Internet security loopholes must be closed. The solution is a firewall system. A firewall sits between the internal protected network and the outside network or the Internet. While it is possible to make a single system fairly secure, it is more difficult to secure all the systems on a private network. There are too many opportunities for program errors or configuration errors.

Using a secure firewall between the Internet and the private network does not eliminate the need for sound security practices on the systems inside the private network. It will, however, significantly enhance overall network security by presenting a barrier to an external intruder.

To succeed in repelling unwanted intruders while still providing access to the outside world the firewall must meet many requirements:

The firewall must hide the structure of the internal protected network from the outside network.

The firewall must provide the necessary outbound services for
users on protected systems.

The firewall must reject unknown protocols.

The firewall must distinguish whether a user comes from an
external unprotected system or an internal protected system.

Only internal users who need access to the outside network and
external users who need access to the internal network should
have proper permissions on the firewall.

The firewall system should deactivate all services that are not
required.

The firewall should maintain an audit trail of system activity. This
should include all successful and unsuccessful attempts to access
your network.

All networks are vulnerable to security risks especially if they are on the Internet. Itek Systems provides innovative, full-service Firewall Solutions by combining the best available products with technical expertise.
