NIST CSF 2.0 - Protect (PR) - Applications for Microsoft 365 (Part 1)
This blog and series will look to apply the National Institute of Standards and Technology (NIST) Cybersecurity Framework (CSF) 2.0 and, specifically, the Protect (PR) Function to Microsoft 365. Though the discussion will endeavor to focus primarily on Microsoft 365, topics may venture into Microsoft Azure topics periodically by the nature of each solution. Part 1 or any subsequent blogs in the series will not be an exhaustive review of all possible applications of NIST CSF 2.0, nor exhaustive of the technologies mentioned and their abilities to manage cybersecurity risks. Other applicable Functions or Categories found in NIST CSF 2.0 will be evoked throughout in the true spirit of the framework. PR as a function is intended to cover “safeguards to manage the organization’s cybersecurity risks” and contains five Categories. The prior CSF publication included six categories, but two were significantly edited and renamed. Let’s first dive into Identity Management, Authentication, and Access Control (PR.AA).Microsoft Copilot for Security and NIST 800-171: Access Control
The second blog in this series will dive into the very first requirement family - Access Control (3.1) - and how organizations may deploy Microsoft Copilot for Security (Security Copilot) to meet the requirements entailed. This requirement family is arguably one of the most paramount because of the remarkable growth in identity-based attacks and the need for identity architects and teams to work more closely with the Security Operations Center (SOC). Microsoft Entra data noted in the Microsoft Digital Defense Report shows the number of “attempted attacks increased more than tenfold compared to the same period in 2022, from around 3 billion per month to over 30 billion. This translates to an average of 4,000 password attacks per second targeting Microsoft cloud identities [2023]”.
