Government buys in to deperimeterised security

Security deperimeterisation is at the heart of plans that underpin the Cabinet Office's high-profile transformational government programme, delegates at the Infosecurity Conference will be told today.

Security deperimeterisation is at the heart of plans that underpin the Cabinet Office's high-profile transformational government programme, delegates at the Infosecurity Conference will be told today.

Increasing demands for public sector bodies to exchange information and share IT services will mean that traditional approaches to security will no longer be appropriate, the Cabinet Office's security adviser will say.

Steve Marsh, director of the Central Sponsor for Information Assurance, said that a new security architecture would play a key role in the transformational government plan.

"The traditional security model of having a hard perimeter to your organisation does not work when you are trying to deliver complex shared services across boundaries. Instead, we need an architecture that reflects the way organisations interact," he said.

The architecture, which is being developed by the Computer Electronic Security Group, and the Cabinet Office's E-Government Unit, would make it easier for government bodies to roll out innovative IT systems, said Marsh.

"It should make it much easier and quicker for departments to respond to their own business needs. In the past it is often thought that the need for security has blocked departments from implementing systems. This should give them the flexibility to meet their business needs."

The architecture, which will be continually updated, will allow organisations to have access to different services under different levels of security clearance, without compromising the security of other sensitive information.

"For the more sensitive services, we will mandate the protection that has to be put around them," said Marsh.
