We have 200 computers in our college campus and all of these connected through LAN and we also have a radio link internet connection, for our 24 hours internet facility. We are accessing internet on both windows and linux machines. We face many problems due to virues, worms and our network has gone down because of server problems.

We have windows based websever and file server so all data is saved to this computer. We want to purchase a Firewall which protect 100% our windows server and clients from viruses, worms and other unwanted files and users access.

Could you suggest a solution?

Dear Rajendra Shakyawal

Viruses and worms will continue to plague our lives forever, so it's best to be proactive.

Here are some suggestions.

• You can use and anti-virus and firewall at the gateway level. And deploy desktop anti-viruses and firewalls on each PC.
• You can purchase separate firewall and anti-viruses or use a multi-function security service that has a combination of firewall, ant-virus, IDS, and spam controller.
• Use a central management console so you can update virus signatures regularly.
• Network security is a combination of technology and culture. You must train the users and make them aware of the need to exercise caution when surfing. You must ask them not to open any attachments without scanning them, not to visit unproductive sites, and not use a floppy or CD-ROM before scanning them first.
• Security is not a one time affair. After you have deployed the solutions and created awareness among the users, you must review the solutions periodically and train each new batch of students.

All the best.

I would like to know if there is any procedure by which an Intelligent Voice Response (IVR) can be added to a toll free number.

Dear Harsh,

An IVR can certainly be added to a toll-free number. The responsibility of making a number toll-free lies with the local telephone exchange, who will send you the bill for all incoming calls.

The IVR server will sit in your premises and will be the gateway point for all incoming calls. Based on the response of the caller the IVR will route the call to the appropriate extension.
