A cybersecurity service assesses, scores, and/or prioritizes activities associated with a directory service. When the directory service is requested to change a directory service assignment, the directory service may first request a verdict from the cybersecurity service. The cybersecurity service may use profiling and/or machine learning to predict directory service assignments. The cybersecurity service may then score and prioritize requests to change/update directory service assignments. Small deviations from predicted directory service assignments, for example, may indicate harmless/normal directory service activity. Larger deviations, though, may indicate abnormal directory service activity. Larger deviations may even indicate malicious directory service activity, such as permission escalation and cyberbreaches. Scoring and prioritization allows for resource allocation and timely mitigations by human experts.
