A method executed by at least one processor (1070, 1080) comprising: determining a first context for a mobile communications device, said context comprising the location of the device, a determination whether the location is included in a predetermined group of locations, and a determination whether a third party's device is attempting to communicate with the mobile communications device via the Bluetooth protocol; determining a first security authentication level that has previously been linked to the determined first context; determining a second security authentication level that has previously been linked to the determined first context, wherein one security authentication level is a higher security authentication level than the other security authentication level, and wherein an authentication policy of the mobile communications device is based on data sensitivity and requires the higher security authentication level if it is determined that a third party's device is attempting to communicate with the mobile communications device via the Bluetooth protocol; allowing access to a first module of the mobile communications device based on the first security authentication level by requiring the user to authenticate using an authentication mechanism that has previously been linked to the first security authentication level; and allowing access to a second module of the mobile communications device based on the second security authentication level by requiring the user to authenticate using an authentication mechanism that has previously been linked to the second security authentication level, wherein one module includes access to business email accounts, business voice mail accounts, and documents stored in segregated memory reserved for business related documents and materials, and another module includes access to personal email accounts, personal voice mail accounts, and documents stored in segregated memory reserved for personal related documents and materials, or in generally available memory, and wherein the method further comprises: receiving a communication from an additional computing node; determining a first characteristic for the communication; and allowing access to the communication by requiring the user to authenticate using an authentication mechanism that has previously been linked to the first or second authentication level based on the first characteristic and the first context. determining a first context for a mobile communications device, said context comprising the location of the device, a determination whether the location is included in a predetermined group of locations, and a determination whether a third party's device is attempting to communicate with the mobile communications device via the Bluetooth protocol; determining a first security authentication level that has previously been linked to the determined first context; determining a second security authentication level that has previously been linked to the determined first context, wherein one security authentication level is a higher security authentication level than the other security authentication level, and wherein an authentication policy of the mobile communications device is based on data sensitivity and requires the higher security authentication level if it is determined that a third party's device is attempting to communicate with the mobile communications device via the Bluetooth protocol; allowing access to a first module of the mobile communications device based on the first security authentication level by requiring the user to authenticate using an authentication mechanism that has previously been linked to the first security authentication level; and allowing access to a second module of the mobile communications device based on the second security authentication level by requiring the user to authenticate using an authentication mechanism that has previously been linked to the second security authentication level, wherein one module includes access to business email accounts, business voice mail accounts, and documents stored in segregated memory reserved for business related documents and materials, and another module includes access to personal email accounts, personal voice mail accounts, and documents stored in segregated memory reserved for personal related documents and materials, or in generally available memory, and wherein the method further comprises: receiving a communication from an additional computing node; determining a first characteristic for the communication; and allowing access to the communication by requiring the user to authenticate using an authentication mechanism that has previously been linked to the first or second authentication level based on the first characteristic and the first context. receiving a communication from an additional computing node; determining a first characteristic for the communication; and allowing access to the communication by requiring the user to authenticate using an authentication mechanism that has previously been linked to the first or second authentication level based on the first characteristic and the first context.
