Psion has launched a guide to help companies manage the roll-out of mobile devices.
The company will offer guidelines on personnel, technical and security issues for IT departments thinking of implementing a handheld computing policy.
There is growing evidence that IT departments will be called to support handheld computers whether they are part of an IT strategy or not.
A recent survey of Palm users showed that 80% of the devices - by far the most commonly used PDA - are synchronised at work.
Psion said that if a company fails to manage the use of its handheld devices it could leave its entire corporate network open to security risks.
Security firm @stake recently discovered that Palm password security can easily be bypassed, debugging functions in the operating system even if Palm's lockout feature is activated. As a result, an unauthorised user could retrieve the system password, obtaining all database and record information on the device, and install or delete applications.
Psion said businesses risk not only security breaches but over-spending and inefficient working practices if they do not set down regulations for users.
As the range of peripherals and handheld devices increases, Psion said its guidelines will help make businesses aware of the issues they face when implementing the PDA in the workplace.
