These enhancements are designed to bolster your defense mechanisms and fortify your digital infrastructure against evolving cyber threats.
Key Improvements:

“First Seen User …” Rule
Our team has fine-tuned these Office 365 rules to optimize threat detection capabilities, ensuring a more precise and efficient response to potential security incidents.

“Abnormal File Share …” Rule
Enhancements to this rule aim to provide better insights into potential abnormalities in file sharing activities, allowing for quicker identification and response to suspicious behavior.
3. Tuning and Improvements to Windows Kerbroasting Detection Rules:
We have refined the Windows Kerbroasting detection rules to enhance the accuracy of identifying and mitigating threats related to Kerberoasting attacks.
4. Bugfix:
“Activity from Disabled User” Windows Check
A bug affecting the "Activity from Disabled User" Windows check has been successfully addressed, ensuring the reliability of this crucial security measure.
5. Syslog Logs Enhancement:
Added port_of_interest field
To accommodate variations in syslog logs from different firewall vendors, we have introduced the "port_of_interest" field, particularly beneficial for scenarios where SourcePort and DestinationPort are switched.
6. Network Machine Learning Models:
Our latest update includes improvements to the Network Machine Learning Models, reinforcing your defense mechanisms with cutting-edge technology.
Added Windows “Aggregator Models”
These models issue alerts when a user triggers an unusual number of alerts in quick succession. This enhancement aids in triaging alerts, providing a more accurate and actionable assessment of potential security incidents.
