The manner in which corporate information is stored and accessed is changing. With these changes, the enterprise faces new risks that must be addressed by information security. Enterprise information security architecture (EISA) using network perimeter and asset-based security models is no longer able to provide the controls and countermeasures needed for organizations to confidently take the new risks.
