Threat Detection

Note: This guide is based on technical research from security logging best practices, machine learning research papers, and analysis of open-source log analysis tools. The techniques described are technically sound and based on documented implementations in production security environments. Code examples use established Python libraries with verified package versions. Readers should adapt these approaches to their specific log formats and security requirements. Security teams drown in log data. A medium-sized enterprise generates terabytes of logs daily from firewalls, IDS/IPS, endpoints, applications, and cloud services. Traditional log analysis—grep, awk, and manual review—doesn’t scale to this volume. ...

Note: This guide is based on technical research from authoritative security sources, NIST publications, MITRE ATT&CK documentation, and open-source security automation frameworks. The techniques described are technically sound and based on documented production implementations. Readers should adapt these approaches to their specific security requirements and compliance needs. Security Operations Centers (SOCs) face an overwhelming volume of security alerts. According to the Ponemon Institute’s 2023 Cost of a Data Breach Report, organizations receive an average of 4,484 security alerts per day, with SOC analysts able to investigate only 52% of them. AI-powered automation offers a path to handle this alert fatigue while reducing mean time to respond (MTTR). ...

As a SOC analyst, one of the most critical tasks is analyzing network flow data to identify potential security threats. In this post, we’ll explore how to combine cloud-based data storage, SQL querying, and AI-powered analysis to streamline this process. Collecting Flow Data in Amazon Athena Amazon Athena provides a serverless query service that makes it easy to analyze data directly in Amazon S3 using standard SQL. Here’s how we set up our flow data collection: ...
