Intelligent security analysis and enforcement for data transfer

A computer program product for managing a message being transferred from a computer, the computer program product comprising:

• one or more computer-readable storage devices and program instructions stored on the one or more storage devices, the program instructions comprising:
• program instructions to determine a level of sensitivity of data in a payload of the message and identify an application initiating a transfer of the data in the message via a network;
• program instructions to determine a level of security protecting the transfer of the data, the level of security indicated by (1) a first setting of the computer that specifies that a first or a second method of encryption at a network layer is applied by a corresponding wireless access point that provides access to the network for the transfer of the data, the first method of encryption having a strength of encryption that is stronger than a strength of encryption of the second method of encryption and (2) a second setting of the application that specifies that a first or a second protocol at an application layer is utilized for the transfer of the data, the first protocol having encryption at the application layer and the second protocol having no encryption at the application layer;
• program instructions to, based in part on the level of sensitivity of the data, determine whether the level of security satisfies a threshold level;
• program instructions to, if the level of security does not satisfy the threshold level and based at least in part on the level of sensitivity of the data and the level of security, determine an action to change the level of security so that the changed level of security satisfies the threshold level, the action to change the level of security including a change to the first setting but no change to the second setting, a change to the second setting but no change to the first setting, or changes to the first and second settings, and in response, execute the action to connect the computer and transfer the message using the changed level of security indicated by the change in the first setting, the change in the second setting, or the changes in the first and second settings;
• and
• program instructions to, if the level of security satisfies the threshold level, connect the computer and transfer the message using the level of security.
