This is part 2 of a 3-part series on how you can
quickly secure your system with a Linux-based SOHO firewall. In
this segment, the author guides you through product selections for
your particular needs and discusses hardware and software costs,
including some that are often overlooked.Small office, home office firewall products, unfortunately, are
still evolving. As a result, IT managers face a multitude of
features in SOHO firewall software programs and hardware devices.
For example, some new products allow centralized monitoring and
policy enforcement for remote desktop firewalls, while others may
be less sophisticated but easier to use. Still other products offer
different configuration options depending on an employee’s role or
on the particular use — personal or business — of the remote
computer.Santa Clara, Calif.-based ISP Exodus Communications, for
example, has deployed CyberwallPlus-SV SOHO firewall software from
Network-1 Security Solutions of Waltham, Mass., on 25 key servers.
The company also has installed ZoneAlarm Pro SOHO firewall software
from San Francisco-based Zone Labs on 2,000 internal PCs. Exodus
plans to install ZoneAlarm Pro on 4,000 computers used by internal,
mobile and home workers.
