Tutorial / Cram Notes
One primary responsibility of a security operations analyst is ensuring that data is retained for the appropriate amount of time as per the organization’s policy and regulatory requirements. Microsoft provides various solutions to manage data retention effectively:
Azure Monitor Logs:
Azure Monitor Logs stores log data in Log Analytics workspaces. Data retention policies can be tailored per workspace. You can configure the retention period anywhere between 30 to 730 days, depending on your requirements. For instance:
RetentionPolicy (Days) | WorkSpace 1 | Workspace 2 | Workspace 3 |
---|---|---|---|
DataRetentionInDays | 180 | 365 | 90 |
Retaining data beyond the default retention period could incur additional costs, so a balance between requirements and costs should be considered.
Azure Sentinel:
When using Azure Sentinel, its retention policies are typically aligned with those in Azure Monitor Logs. By default, Azure Sentinel offers 90 days of free data retention but allows for custom retention periods tailored to organizational needs.
Alert Notification Management
Alert notifications are vital in keeping relevant stakeholders informed about security incidents as they arise.
Azure Security Center:
Azure Security Center provides a central view of security alerts and can send notifications via email to specified email addresses when new alerts are triggered. It can be configured to send alerts for high severity issues or according to specific criteria through:
Alert Severity Level | Email Recipients |
---|---|
High | [email protected] |
Low | [email protected] |
Email Notifications:
In addition to Azure Security Center, Azure Monitor and Azure Sentinel can also be set up to send email notifications based on alerts. Automation rules can trigger notifications or run playbooks to respond to specific alert types or severities.
Advanced Features
For a Security Operations Analyst, making use of the advanced features of Microsoft’s security tools is necessary for a robust security posture.
Advanced Hunting in Microsoft 365 Defender:
The Advanced Hunting capability allows you to proactively hunt for threats across devices, emails, apps, and identities in your organization. It uses a Kusto query language (KQL) to sift through historical data. For example:
DeviceLogonEvents
| where Timestamp > ago(30d)
| where AccountName == “suspiciousUser”
| summarize Count = count() by DeviceName
This query checks for logon events in the past 30 days related to “suspiciousUser” and summarizes the count by device.
Threat Intelligence:
Microsoft Threat Intelligence provides insights about the threat landscape which can be leveraged to secure the organization’s entities better. It analyzes data from your organization, the industry, and globally, providing actionable intelligence.
Security Orchestration Automated Response (SOAR):
SOAR, as part of Azure Sentinel, offers the functionality to automate responses to specific alerts. Using playbooks (based on Azure Logic Apps), responses range from simple notifications to complex remediations.
Ensuring that you have a comprehensive understanding of managing data retention, alert notifications, and the aforementioned advanced features is crucial for the exam. Moreover, it is also imperative for a security operations analyst to implement these practices in the context of protecting an organization’s digital assets.
