Microsoft patents cloud security tool that flags odd activity with unique codes
Microsoft describes a system that creates a unique digital code, or fingerprint, for every action happening in a cloud environment. It uses a machine learning model to combine details from activity logs into a single string and then converts that string into a fixed-length code. If the resulting code does not match expected patterns, the system flags the activity as an anomaly to help identify potential security risks.
In the filing’s own words
The present disclosure relates to systems and methods for identifying cybersecurity risks in a cloud environment. The systems and methods generate a unique fingerprint for an event in the cloud environment using a hash structure. The systems and methods detect an anomaly in the event using the fingerprint. The systems and methods use the anomaly in identifying a cybersecurity risk in the cloud environment.
What exactly they claim (claim 1)
1. A method comprising: extracting, by a machine learning model using a hash structure, information from fields in an activity log of an event; forming, by the machine learning model, a composite string with the information; applying, by the machine learning model, a hash function to the composite string; generating, by the machine learning model, a fingerprint for the event in response to applying the hash function to the composite string, wherein the fingerprint is a unique value for the event; identifying, using the fingerprint, an anomaly in the event; and performing an action in response to identifying the anomaly.
