Let’s take a detailed look at the sort of security required
by today’s corporate information systems. First, it is
important that coverage is provided for the entire system, not
just part of it. This is not an easy task. Information systems
are put together using a variety of different technologies,
and the network environment can stretch from corporate LANs
to the Internet and even to mobile phones. If there is just
one weak point in all of this, you can be sure it will not be
missed by the cyber criminals. So what can one do?
The answer is systematic security. Mitsubishi Electric can deliver
security that covers every aspect of your information system,
from the hardware and networks to your business applications.
We have the libraries to build MISTY and other advanced security
technologies into your system. We have the software for verification
servers, secure Web access, and file encryption systems. And
by combining these technologies with the appropriate hardware
- servers, client PCs and smart cards - we can provide the required
security for all of your corporate activities.

Another important point is suitability for your business model.
For example, the B2B and B2C services offered via the Internet
require a mechanism for the encryption of communications and
access control in order to protect transaction data and personal
information - without impairing the ease and convenience that
are the great advantages of the Web. Moreover, if your business
system is designed to be used by a mobile sales force, you will
certainly need file encryption tools to guard against the eventuality
of a laptop being stolen. And for a service based on the use
of prepaid cards, a major priority will be measures to prevent
the counterfeiting of cards. Unless you look ahead at the sort
of risks that your business model will face and take the necessary
countermeasures, then you will not be able to reap the rewards
of pioneering new business opportunities.
In order to predict risk, a software engineer must be well versed
not only in security technologies but also in the nuts and bolts
of the business itself. For vendors that supply only security
technologies, this may be a tall order. But it is second nature
for us at Mitsubishi Electric, because we have many years of
experience in building business systems. In fact, business solutions
featuring the optimum security measures to protect against cyber
crime are already supporting many business models.
| Advanced security technologies
are making entirely new business models possible. One
example is the world’s first digital watermarking
device for moving pictures, which was jointly developed
by Mitsubishi Electric and NHK’s Broadcasting Science
Research Laboratory. This revolutionary technology,
capable of embedding copyright information in a video
stream in real time, is expected to bring about a sea-change
in the video production business, which has long been
plagued by illegal copying and distribution. Solving
such copyright problems opens the door to full-fledged
content distribution via digital broadcasting and over
the Internet. |

Impressed? Security that can be used throughout a network, security
technologies that suit different types of business model, and
compatibility with all aspects of commercial activity - this
“ubiquitous security” is what will support businesses
in the network age. |
