Tutorial / Cram Notes
Security baselines in Azure are founded on the principles of the Azure Security Benchmark, which provides recommendations that are specific to Azure. Moreover, Microsoft also aligns with the Center for Internet Security (CIS) Benchmarks, which provide well-defined, unbiased, consensus-based industry best practices to help organizations assess and improve their security.
When implementing security baselines, Azure customers can benefit from the various tools and services provided. For example, Azure Security Center (ASC)—recently rebranded as Microsoft Defender for Cloud—provides a unified security management system that strengthens the security posture of your data centers, and includes a secure score feature that can help you understand your current security situation.
Key Components of Azure Security Baselines
- Azure Policy: Implements, enforces, and audits security policies to ensure compliance with security baseline settings. Azure Policy evaluates resources in Azure for compliance with defined policies, helping to enforce organizational standards and to assess compliance at scale.
- Azure Blueprints: Help to automate the deployment of various resource templates and other artifacts such as role assignments, policy assignments, Azure Resource Manager templates, and Resource Groups all packaged together.
- Azure Security Center: Provides advanced threat protection and unified security management for systems in Azure, on-premises, or in other clouds. It offers insights into the security state of your resources and helps to detect and respond to threats.
Examples of Security Baseline Controls
- Identity and Access Management: This control ensures that only authorized and authenticated users can access Azure resources. It involves practices like multi-factor authentication, role-based access control, and stringent password policies.
- Data Protection: Azure recommends encryption for data at rest and in transit. For example, Azure Disk Encryption and Azure SQL Transparent Data Encryption can be utilized to protect your data within Azure services.
- Resource Management: To control and strengthen the way Azure resources are provisioned and managed, Azure Resource Manager (ARM) is used for deployment, management, and monitoring of all resources.
- Network Security: Azure Security Baselines recommend the use of Network Security Groups (NSGs), Azure Firewall, and other services to segment networks and control inbound and outbound traffic.
Comparing Security Baselines
The following table compares baseline control categories across different Azure platforms:
| Security Control Category | Azure Compute | Azure Storage | Azure SQL Database |
|---|---|---|---|
| Identity and Access Management | MFA, RBAC | RBAC, AAD Auth | SQL Auth, AAD Auth |
| Network Security | NSGs, Firewall | VNet Integration | Firewalls, VNet |
| Data Protection | Disk Encryption | Storage Service Encryption | TDE, Always Encrypted |
| Monitoring and Logging | Azure Monitor | Storage Analytics | SQL Auditing |
| Patch and Vulnerability Management | Regular updates | N/A | Automated Patching |
By comparing these security baseline controls, organizations can understand the specific requirements and recommended practices for securing their resources within different Azure services.
Implementing Security Baselines in Azure
The implementation of security baselines is pertinent to maintaining a strong defense against cybersecurity threats. Organizations are encouraged to review these baselines and adapt them to their specific needs or regulatory requirements. The use of Azure Policy and Azure Blueprints can significantly streamline the enforcement of these security baseline settings across your cloud environment.
In essence, Azure security baselines empower organizations with guidance to configure and manage their resources following security best practices, reducing the attack surface and mitigating the risk of security breaches. For those preparing for the SC-900 Microsoft Security, Compliance, and Identity Fundamentals exam, a deep understanding of these baselines is essential for ensuring the security and compliance of your Azure deployments.
