Monitoring is a crucial aspect of Machine Learning Operations (MLOps) in data intelligence platforms like Databricks, as it ensures the effective performance of machine learning models. MLOps focuses on automating and streamlining the lifecycle of ML models, from development to deployment and monitoring. Effective monitoring helps maintain data quality, detect issues early, and ensure overall system health. The core principles of MLOps emphasize automation, collaboration, and monitoring to improve the scalability, reliability, and maintainability of ML models in production environments. Monitoring is essential for maintaining model accuracy over time by tracking performance metrics and identifying potential data quality problems. Integrating tools like ChaosSearch with Databricks can help manage diverse log formats, simplify complex JSON data processing, and enhance querying and alerting capabilities, which are crucial to MLOps monitoring.

The MITRE Adversarial Threat Landscape for Artificial Intelligence Systems (ATLAS) framework is a knowledge base of documented and categorized cyber threats against AI systems, detailing 14 adversarial tactics used by digital adversaries. MLOps monitoring is the continuous process of monitoring, tracking, and observing ML models deployed in production environments to detect security threats against AI systems. The MITRE ATLAS framework can be used with MLOps monitoring to help detect cyber threats against AI systems, including data poisoning, ML evasion attacks, supply chain compromise, LLM plugin compromise, and LLM prompt injection.

Insider threats are responsible for 60% of data breaches and can cost an average of $16.2 million per incident. Log analytics is a valuable tool for detecting these threats by monitoring user behavior and security logs in near real-time against established baselines and policies. Malicious, compromised, and negligent insiders represent three types of insider threats that can be detected through proactive security analysis using log analytics. Key indicators to monitor with log analytics include suspicious login behavior, unauthorized or unnecessary application usage, unauthorized file access/modification, privilege escalation, excessive downloads, inappropriate data exfiltration, and anomalous software installation. By aggregating security and user behavior logs at scale, organizations can establish baselines for normal user behavior and monitor incoming log data to detect suspicious or anomalous activity that might indicate an insider threat.
