"The risk of malicious activity has never been more of a reality for organizations. End users today access, process, and manage privileged data more than ever as part of their job. This need for employees to use privileged data puts the organization at risk of malicious actions that include data theft, destruction, manipulation, and ransom. And it’s not just theory, a full one third of reported insider incidents in 2015 involved end users who access sensitive data as a requirement to do their jobs .
This raises the question of why a seemingly loyal employee would turn and even contemplate stealing data, let alone take action. Approximately half of insider incidents have a financial motive1 . There are plenty of buyers of credit card data, social security numbers, and healthcare data – all with per-record market rates ranging from one cent to well over $1,000.

It’s so utterly difficult to spot the difference that 70% of insider incidents take either months or years to be detected1 . To help address the growing problem, Carnegie Mellon University’s Software Engineering Institute (SEI), which includes their worldrenown CERT division, released a Common Sense Guide to Mitigating Insider Threats. The guide contains 19 practices to protect your organization from insider threats. One of the key ways to reduce the risk of insider threats this paper will focus on is found in Practice #4, entitled
