Microsoft was unable to store security log information for multiple cloud products used in its cloud technology due to a software error. For more than two weeks last month, users' security log information could not be stored because of the problem, the company said. According to Microsoft, the flaw may cause problems in identifying security risks even if no user data is deleted.

Microsoft Cloud Technology

It is known that from September 2 to 19, Microsoft's cloud-based identity management technology Entra, Sentinel, Defender for Cloud and Parview had errors in their security logs. In a message sent to cloud users in this regard, Microsoft said that the security log information upload method did not work due to an error in the internal monitoring agent. This resulted in cloud product security log information not being stored for more than two weeks.

Security logs of user sign-ins are essential for using various Microsoft services. If the information is not stored in the security log, it is difficult for Network Defender to find any suspicious sign-in information at that time. However, a Microsoft official assured the cloud users that there was no security risk even though there was a problem in storing information in the security log due to operational errors.
