Microsoft patents system to flag suspicious cloud admin actions

Patent drawing
Patent drawing from the official filing.

Microsoft has patented a method for detecting suspicious behavior in cloud environments by analyzing logs of administrative actions. The system compares current operations against the historical patterns of the service provider to calculate a risk score. If the activity looks unusual, the system automatically generates a security alert.

Why it mattersThis is interesting for organizations relying on cloud services, as it adds an automated layer of defense against insiders or compromised accounts performing unauthorized changes.

In the filing’s own words

Malicious service provider activity detection is enabled. A first log is obtained. The first log comprises a record of a first control plane operation executed on behalf of a first entity. A service provider associated with the execution of the first control plane operation is identified. The service provider has privileges to execute control plane operations on behalf of the first entity. A first malicious activity score is determined based at least on the service provider. The first malicious activity score is indicative of a degree to which the first control plane operation is anomalous with respect to the first entity. A determination that the first control plane operation potentially corresponds to malicious activity is made based at least on the determined first malicious activity score. Responsive to determining that the first control plane operation potentially corresponds to malicious activity, a security alert is generated.

What exactly they claim (claim 1)

1. A method comprising: obtaining a first log that comprises a record of a first control plane operation executed on behalf of a first entity; identifying a service provider associated with the execution of the first control plane operation, the service provider having privileges to execute control plane operations on behalf of the first entity; determining, based at least on a comparison of the execution of the first control plane operation and historic activity of the service provider, a first malicious activity score indicative of a degree to which the first control plane operation is anomalous with respect to the first entity; determining, based at least on the determined first malicious activity score, the first control plane operation potentially corresponds to malicious activity; and responsive to determining that the first control plane operation potentially corresponds to malicious activity, generating a security alert.
