Export Anomalies, Threats, Incidents and the Audit Log to a SIEM
You can export anomalies, threats, incidents, and the Audit Log from Skyhigh CASB to your third-party SIEM systems using Syslog export. This export is handled through the Skyhigh Cloud Connector. Use this feature to export data to another system for further analysis or to drive data protection rules.
By default, Cloud Connector fetches incidents from Skyhigh CASB every four hours. You can customize this interval in the logprocessor.local.properties file using the property siem.frequency=. The value is in milliseconds. For assistance setting this property, contact Skyhigh CASB Support.
NOTE: If tokenization for Skyhigh CASB Secure data is enabled, there may be situations where your data will not be detokenized before it is sent to your SIEM. Data can be detokenized automatically only when the user name associated with the user in Active Directory matches the user name used in the monitored CSP.
