Remote security – inexpensive firewalls

Most organizations still rely solely on VPN and RACF to protect

mainframe access from remote workstations connected via commercial

high-speed Internet – despite the fact that those workstations are

unprotected from hackers gaining access to them from the Internet,

and going on to take over a logged-on RACF session.

A random check of a major telco confirmed that it doesn’t even

recommend, let alone require, a firewall for employees connecting to

the mainframe from high-speed Internet at home. Ironically, it tells its

residential customers to install a firewall because, like virtually all

ISPs, the telco’s firewall protects its staff, not its customers.

In our continuing look at SOHO hardware firewalls for the small

remote office or home mainframe user, we switch to cable/DSL

gateway routers with built-in firewalls and VPN, instead of the much

more expensive firewall with built-in hub. Of course, software firewalls

are even cheaper, or free with the operating system, as in Windows XP.

But they leave the operating system itself unprotected against a direct

attack.

BELKIN

The Belkin 4-Port Cable/DSL Gateway Router (F5D5230-4) is an

unusual shape, sits vertically, and has a docking ring to physically

attach (side-by-side) with other Belkin products. Although the small

installation manual suggests answering some networking questions

first and installing set-up software on your workstation, you’ll find it

faster to just connect your modem and workstation(s), and then power

up the router and see if it works. It worked for me with my ADSL

modem, and Windows XP Professional and Windows 2000 Server

workstations, but I:

• Use dynamic IP addresses (DHCP)

• Do not use PPPoE

• Previously had the two workstations communicating with each

other through the hub of a SOHO firewall.
