Internet Services Access and Firewall
The basic Tri-Net server solution provides a firewall and simultaneous access to Internet services for all computers on the user's internal network. The firewall prevents unauthorized users on the Internet from using any services or accessing any files on the local network or Tri-Net server. The server can cache web sites that have been accessed. Once a site is cached, it is accessed directly from the Tri-Net server, resulting in more efficient use of the Internet connection. The server is configured so that client machines can route Internet requests, e.g. ftp, through the server.
Virtual Private Network (VPN)
VPN can be described as
the ability to 'tunnel' through the Internet, or any other public network,
using encryption technology in a way that provides the same security
formerly only available on expensive private networks. It allows a user
working at home, or elsewhere, to simply connect to their local Internet
service provider and securely link to their remote corporate network as if
the user was in the building. Corporations with multiple remote sites each
having Internet access can establish private connections between the
remote networks to allow clients in each site to share resources in a
completely secure environment.
The Tri-Net server provides comprehensive e-mail facilities to handle both internal and Internet e-mail requirements. Among the e-mail facilities supported is a complete POP3/SMTP based internal e-mail system. In addition, users have the ability to access their mail remotely via the Internet. The server can also handle all of the Internet mail for a registered domain with no requirement for e-mail accounts at an Internet Service Provider. DNS services can be provided by Tri-Lan. Facilities are provided to allow the system administrator to create and manage an unlimited number of e-mail accounts.
This provides the capability to develop an Intranet and to develop and host web pages. It also provides the capability for the system administrator to control web sites that users can access. This is accomplished by providing the system with a list of web sites that are to be blocked. For blocked sites, complete or partial URL addresses will be accepted.
This feature provides the ability for the system administrator to view the complete history of web sites accessed and e-mail transactions that have been handled by the proxy server. This information can be accessed by date and time of day or by specific computer.
In addition to its standard features, the Tri-Net system can be tailored to meet custom requirements. Some that can be readily implemented include:
Custom configuration is not limited to these ideas. Since the Tri-Net system is built upon Linux other features can be developed to meet specialized customer requirements.
