The 'Snowflake Alter Integration' detection rule is designed to monitor changes made to integrations within a Snowflake database environment. It specifically queries the Snowflake account usage logs to identify recent alterations to integrations, focusing on events occurring within the last two hours. The detection logic searches for SQL queries that include the words 'integration' and 'alter', which indicates that an integration's properties are being modified. This behavior is associated with potential persistence and account manipulation techniques by attackers, who may seek to gain unauthorized control over account integrations for malicious purposes. Monitoring such activity is crucial for maintaining the security posture of Snowflake environments and ensuring that only legitimate changes to integrations occur. The rule taps into application logs generated by Snowflake to capture relevant events related to integration management and helps in detecting various threat techniques such as valid accounts exploitation and account manipulation.
