Azure Security Basics: Log Analytics, Security Center, and Sentinel

## Executive Summary This blog post is a practitioner-focused tutorial describing how to set up Azure Log Analytics and Azure Sentinel for security monitoring: creating a workspace, connecting virtual machines via the Log Analytics agent, installing agents, enabling Security Center standard tier and continuous export for security events, and estimating operational costs (noting Advanced Threat Protection can be expensive). It is instructional guidance rather than an incident report or threat intelligence analysis.
