Ensure that an Azure activity log alert is fired whenever “Create” or “Update Network Security Group Rule” events are triggered within your Microsoft Azure cloud account. Activity log alerts get activated when a new activity log event that matches the condition specified in the alert occurs. In this case, the alert condition required is 'Whenever the Administrative Activity Log "Create or Update Security Rule (networkSecurityGroups/securityRules)" has "any" level, with "any" status and event is initiated by "any"'.
This rule resolution is part of the Conformity Security & Compliance tool for Azure.
Monitoring your Microsoft Azure account for “Create” or “Update Network Security Group Rule” events can give you insights into the cloud network access changes and can help reduce the time it takes to detect suspicious activity.
