In the Introduction we add the following:
This integration in cybersecurity is demonstrated by various real-world applications and case studies, highlighting their efficacy in enhancing cyber defense mechanisms. A globally recognized Fortune 500 telecom company employed Snorkel Flow to classify encrypted network data flows into their associated application categories. They faced challenges like slow manual labeling of network traffic data and the need for adaptable solutions. Snorkel Flow enabled the telecom company to quickly produce a large training dataset for ML models, resulting in a system 26.2% more accurate than the baseline model and nearly as accurate as a fully-supervised model trained on all ground-truth examples. This approach allowed the company to develop adaptable solutions that outperformed static rules-based approaches, especially in dynamic data environments like SNIs [2].  Snorkel Flow has no-code UI support for rapidly creating labeling functions with network data [2] A second case study concerned a major AI center within the U.S. government that selected Snorkel Flow for developing AI/ML applications in cybersecurity. They used Snorkel Flow to programmatically label nearly 280,000 records for application type classification. The dataset consisted of network packets with over 2.7 million total records, described using various data features. The Snorkel Flow model was able to effectively use non-servable features like destination IP for labeling training data while relying on more reliable packet statistics for actual model training and prediction [2]. Building and deploying labeling functions (LFs) with Snorkel Flow [2] These examples illustrate the transformative role AI and ML play in various aspects of cybersecurity, from detecting and responding to threats to predicting vulnerabilities and enhancing incident response. As cyber threats become more sophisticated, the integration of these technologies in cybersecurity tools becomes increasingly vital for maintaining robust defense mechanisms.
