[Modus] Firewalls for ISPs

[Admin]

We are a small ISP and are concerned about the increase in security problems in Windows.  It seems every few days Microsoft releases security patches.  I have also seen on the Internet that source code for Windows 2000 and NT have leaked out on the Net.   We use all Windows servers connected to the net through a Cisco 2620.  My question is this.... What do the rest of you do for firewall protection? Am I going to have to invest is an expensive hardware firewall and hire on an employee (which I can't really afford) to do full-time security maintenance?     AK Internet Less expensive and more personal than Earthlink, AOL, and MSN 641 E. 10th Avenue Bowling Green, KY  42101 270-793-0647 voice 270-843-7532 fax [EMAIL PROTECTED]
