Perils of Mobility
As mobile device worms and viruses become more prevalent, security likely is to become a key differentiator in the mobile market .
In June 2005, when a computer worm attacked mobile
devices for the first time in history, the technology industry
was caught completely off guard. The worm, dubbed
Cabir, spread via Bluetooth and infected cellular phones and
other devices running the Symbian operating system. Luckily,
the worm was harmless and did not wreak any widespread
infections. Still, Cabir served as a wake-up call to CIOs and IT
managers alike-at a time when the security of corporate infor-
mation is of utmost importance. It proved that not even mobile
devices are immune to attack.

Since the advent of Cabir, a number of other worms and
viruses have attacked smartphones and other handheld
devices. Because many business professionals check email
and surf the Web on their mobile devices, these threats have
jeopardized corporate security. In contrast to standard cellular
phones, which usually store little more than phone numbers
and addresses, new mobile devices may host any type of file
that can be stored on a PC hard disk drive. Programs that give
access to password-protected online services such as instant
messaging can also be used on smartphones, which places
confidential data at even further risk.
Currently, there is no threat of a global epidemic caused by
mobile worms or viruses. However, this situation undoubtedly
will worsen as mobile devices are shifted to standard platforms
and virus writers find new ways to create chaos for the corpo-
rate world. Security experts at Gartner, Yankee Group, and a
variety of other research firms predict that 2006 will be the year
of the mobile-device virus. Rather than react to an outbreak
after it occurs, network administrators should proactively work
to secure mobile devices against malicious code before the
next big threat materializes.
The burden to control access does not only fall on corporate
users-cellular and wireless service providers have the power
to provide security, as well. Few present-day regulations
require these companies to include any security provisions
whatsoever. Many of these companies offer security, but
customers have to pay separately for it. As mobile device
worms and viruses become more prevalent, security likely is
to become a key differentiator in the mobile market. Another
way network administrators can secure their networks is by
insisting that antivirus protection be part of their standard
Service Level Agreements.

All about policy
Controlling control
It's no secret that security is a balance between risk and acces-
sibility. When administrators make the network more secure, it
is harder for users to gain access. When they improve access,
security usually drops precipitously. With this in mind, com-
panies that allow employees to access their networks through
personal digital assistants (PDAs) and other handheld comput-
ers need to require mobile devices to connect through separate
firewalls. Wherever these firewalls are placed-on the network
perimeter or on the devices themselves-they ensure that traffic
is secure when it hits the network core.
All about Policy
Common sense dictates that a homogeneous network is
infinitely easier to control than a heterogeneous one. Forward-
thinking network administrators understand this inherently and
make sure that they outline acceptable mobile devices from the
very beginning. This task is harder than one might think, largely
because many employees purchase their own mobile devices,
so setting and enforcing mobile security policy can be next to
impossible. Still, by establishing expectations early in the game,
network administrators can eliminate this issue before it is even
close to developing into a problem.
Once network administrators have set policy on acceptable
mobile devices, they must communicate that policy effec-
tively. For most IT organizations, communication consists of
sending out a memo that users must read, sign, and return.
In securing mobile devices, however, a more formalized edu-
cation process is necessary to teach users why it is important
to follow the rules. If one user fails to follow instructions, the
entire network could be compromised. This makes it critically
important that users understand which devices they can
use when they interface remotely with critical company
IT resources.
Architecting a b behind-the-scenes defense is only
part of the puzzle. For security measures to function most
efficiently, companies also must deploy frontline defenses on
mobile devices themselves. By supporting Pocket PC 2003
and 2003 Second Edition, VPN-1 SecureClient from Check
Point Software Technologies enables PDAs and handheld
computers to access resources protected by VPN-1 gate-
ways. The solution maximizes endpoint security for mobile
devices of every kind, making mobility a safer proposition for
users and network administrators alike.
Be an architect
Finally, you cannot achieve unified security policy for mobile
devices without designing a unified security architecture for
your enterprise as a whole. In many cases, IT organizations
have one group managing network security and another
group managing mobile and telecommunications devices.
This setup is a recipe for miscommunication and abject
failure. The very best organizations have the same team
of security professionals in charge of security for both the
network and for mobile devices. In this way, companies can
avoid having one security solution for mobile phones and
another for everything else.
