Data networks represent the glue that pulls organisational information together and allows or denies access for consumers of the organisations information. Today the boundaries of the corporate network often extend beyond the companies premises and with the mobility of new types of end user computing devices traditional network borders are changing. Organisations want borderless access to corporate information whether they are in the office on a PC or out of the office and they want it through mobile phones, tablet computers, hybrids and other devices. Corporate access from both public and/or private locations is expected.
