Write a 3 to 5 paragraph briefing paper that identifies and explains the three most important reasons why Sifers-Grayson should invest in an Identity Governance & Administration solution to help combat insider threat.

Your audience is a mixed group of managers from across Sifers-Grayson's operating areas (company HQ's, Engineering, Finance & Accounting, Program Management, Sales & Marketing). Some of these managers are familiar with the importance of separation of duties and least privilege but most are not. One or two of the managers might know the definition for RBAC. Your briefing paper needs to address these information needs as well as discussing why information should be labeled as to its sensitivity ("classification") and ownership.

Provide in-text citations and references for 3 or more authoritative sources. Put the reference list at the end of your article.
