1. A method for improving security in a computer network, comprising the steps of: obtaining operational data for at least a first networked application, wherein said operational data is generated during normal operation of said first networked application; obtaining enterprise data for at least a second networked application, wherein said enterprise data is maintained independent of said normal operation of said first networked application; correlating said operational data with said enterprise data to obtain correlated data; and using said correlated data to improve security of said computer network, wherein: said operational data comprises a record of a unique address allocation to a user device attempting to access said computer network; said enterprise data comprises credentials associated with local authentication at said user device; the step of correlating said operational data with said enterprise data to obtain correlated data comprises associating said unique address and said credentials with authentication information stored in a single-sign-on server; and the step of using said correlated data to improve security of said computer network comprises providing a user of said user device with single sign-on ability responsive to an indication of an appropriate match between said unique address and said credentials and said authentication information, wherein one or more steps of said method are performed by a hardware device.
