The Azure Log Analytics agent for Windows will begin to use SHA-2 signing exclusively on Aug. 17, 2020. This date has been extended from May 18, 2020 to give customers more time to prepare.
The change will impact customers using the Log Analytics agent on a legacy OS as part of any Azure service (Azure Monitor, Azure Automation, Azure Update Management, Azure Change Tracking, Azure Security Center, Azure Sentinel, Windows Defender ATP).
This change requires action only if you’re running the agent on a legacy OS version (Windows 7, Windows Server 2008 R2, or Windows Server 2008). Customers running on a legacy OS version are required to apply the latest service updates and patches on their machines before Aug. 17, 2020, or their agents will stop sending data to their Log Analytics workspaces.
