What measures should an organization take when it planning to deploy WIFI access to their information systems?
Using Omni directional antennas?
Employ only radio devices on systems that have been encryption enabled
Conduct periodic surveys to understand the radio frequency profile of organizational information systems?
Increase the power of the wireless transmissions to so that the signal can be received clearly?
Actions that may be taken by organizations to limit unauthorized use of wireless communications outside of organization-controlled boundaries include, for example: (i) reducing the power of wireless transmissions so that the transmissions are less likely to emit a signal that can be used by adversaries outside of the physical perimeters of organizations; (ii) employing measures such as TEMPEST to control wireless emanations; and (iii) using directional/beam forming antennas that reduce the likelihood that unintended receivers will be able to intercept signals. Prior to taking such actions, organizations can conduct periodic wireless surveys to understand the radio frequency profile of organizational information systems as well as other systems that may be operating in the area.
