Microsoft Sentinel Analytics
To return a dataframe detailing all configured alert/analytics rules configured with Microsoft Sentinel call list_alert_rules. The returned dataframe includes scheduled queries, as well as Fusion based detections. The returned dataframe include details of the rule configuration as well as the query run (where applicable).
You can also return details of avaliable Analytic templates with list_analytic_templates.
To create a new analytic rule you can use create_analytic_rule. With this function you can create a new analytic rule either from an analytic template or with a set of custom details.
When creating an analytic if a template name or ID is provided details from that template will be used.
Otherwise you can specify details manually. Request elements include: -name: The name to give the analytic. -query: The KQL query string to use in the anlaytic. -query_frequency: How often the query should run in ISO8601 format, by default “PT5H” (or 5 hours) -query_period: How far back the query should look in ISO8601 format, by default “PT5H” (or 5 hours) -severity: The severity to raise incidents as, by default “Medium” but options include “Informational”, “Low”, “Medium”, “High” -suppression_duration: How long to suppress duplicate alerts in ISO8601 format, by default “PT1H” (or 1 hour) -suppression_enabled: Whether you want to suppress duplicates, by default False -trigger_operator: The operator for the trigger, by default “GreaterThan”. Options include “Equal”, “NotEqual”, “LessThan”, “GreaterThan” -trigger_threshold: The threshold of events required to create the incident, by default 0 -description: A description of the analytic, by default None -tactics: A list of MITRE ATT&CK tactics related to the analytic, by default None -enabled: Whether you want the analytic to be enabled once deployed, by default True
