Least Privilege Management (LPM) is in the news …
The concept has been around for decades. J. Wolfgang Goerlich, information systems and information security manager for a Michigan-based financial services firm, said it was, “first explicitly called out as a design goal in the Multics operating system, in a paper by Jerome Saltzer in 1974.”
But, it appears that so far, it has still not gone mainstream. Verizon’s 2012 Data Breach Investigations Report found that, of the breaches it surveyed, 96% were not highly difficult for attackers and 97% could have been avoided through simple or intermediate controls.
“In an ideal world, the employee’s job description, system privileges, and available applications all match,” Goerlich said. “The person has the right tools and right permissions to complete a well-defined business process.”
“The real world is messy. Employees often have flexible job descriptions. The applications require more privileges than the business process requires,” he said. “[That means] trade-offs to ensure people can do their jobs, which invariably means elevating the privileges on the system to a point where the necessary applications function. But no further.”
