Powergen Deploys the Full Range of Xiscan Products &
With deregulation of the energy and telecoms markets, the
Utilities sector has become one of the most dynamic sectors in the UK
With the acquisition of TXU's retail business, Powergen (now E.ON UK)
became the UK's number one electricity supplier with around 6 million gas and
electricity customers and number two in energy with around 8.4 million
electricity and gas accounts. The company is a part of E.ON AG - the world's
largest investor-owned utility.
With such a diverse and rapidly expanding range of business
activities (from operating power stations to running intensively
customer-facing businesses) Powergen relies heavily on a wide range of computer
systems. For most modern companies, computer security is integral to business
operations. One area often overlooked, however, is the interface between data
and voice (telephony) networks. Aware of the specific risks that this
increasingly tight integration presents, Powergen has opted to use Xiscan to
quantify and assist in the management of computer access through the telephone
Xiscan is a tool specifically designed to locate modems
providing access to an organisation's data network.
Powergen chose to use the full range of Xiscan services.
Xiscan was delivered as a preinstalled turnkey solution. Powergen used Xiscan
consultants to perform production configuration in conjunction with key
Powergen staff to model Powergen's telecommunications infrastructure. The
result was a set of scan schedules designed around the specific operational
characteristics of each of Powergen's different business units. Using these
schedules, Xiscan consultants performed extensive daytime, nighttime and
weekend scanning, completing over 73,000 calls over the audit period. The
output was a detailed and comprehensive analysis of the state of modem
connectivity throughout Powergen. Subsequently, on-site training of Powergen
staff has been provided to allow them to fully understand Xiscan in a
day-to-day operational capacity.
Using the full range of Xiscan services has allowed Powergen
to take a proactive role in managing modem security. The initial involvement of
experienced consultants has fast-tracked the normal learning process, allowing
Powergen to get the most out of Xiscan from day one. In addition, one of the
peripheral benefits from the Xiscan audit has been a better understanding of
the voice telephony network. This has allowed Powergen to critically examine
areas where there is capacity in excess of that required for business
resilience, with the potential for corresponding cost savings.
Xiscan takes security controls from reactive to
proactive vulnerability detection - finding problems before they find you. It
is proving to be the ultimate 'wake up call' for telephony line ingress
