CISA’s New Playbook Guides Government Agencies and Enterprises on Utilizing Microsoft’s Expanded Cloud Logs

Microsoft has upgraded its cloud logging capabilities following a security breach in July 2023, which impacted various U.S. government officials. In response, Microsoft has now made enhancements to its Purview Audit Standard offering, expanding logging services for all users. This move has prompted the Cybersecurity and Infrastructure Security Agency (CISA) to release a comprehensive 60-page playbook to assist government organizations and enterprises in leveraging these updated features.

The playbook delves into the increased monitoring and analysis opportunities presented by the expanded logs within Microsoft services. It equips users to track user and admin actions across multiple Microsoft solutions, enhancing threat detection capabilities against activities such as business email compromise (BEC) and nation-state threats. Additionally, the guidance provides insights on utilizing the enhanced logs within Microsoft 365, as well as integration with security systems like Microsoft Sentinel and Splunk SIEM.

In July 2023, a state-sponsored Chinese threat actor exploited a vulnerability in Microsoft Outlook, compromising email accounts of government entities. This incident prompted Microsoft to strengthen its security measures, including revoking compromised security keys, fortifying token validation systems, and improving incident reporting transparency. Subsequently, Microsoft initiated its Secure Future Initiative in November 2023, focusing on bolstering cybersecurity practices and investing in advanced threat detection and response mechanisms.
