Hello COS, 5 Microsoft services are hosted on IP address in question. These services are used for activation and update stuff. Refer Bellow mentioned link. https://www.robtex.com/dns/co2.sls.microsoft.com.html Traffic log says application is "ms-product-activation". Hence I believe some of the applications are trying to activate itself. Collect source IP addresses and provide it to system team to find out root cause of simultaneous activation logs. Bottom line is its not a threat, its genuine traffic. Even SIEM says Excessive session, not malicious session. Its just an alert to administrator, so he can varify if destination is malicious[torrent/bot/etc]. Regards, Hardik Shah
