Why security is important?

In today’s digital landscape, securing cloud environments is more critical than ever. Microsoft Azure provides a comprehensive set of security capabilities designed to help organizations protect their workloads, data, and identities. From identity management to threat protection, Azure’s built-in security features support compliance and resilience against cyber threats.

Let’s take a closer look at some of Azure’s key security technical capabilities and how they help organizations strengthen their cloud security posture.

🔐 Identity and Access Management (IAM)

Azure provides strong identity and access management tools to ensure that only authorized users can access resources.

• Microsoft Entra ID – Enables secure authentication and access control https://learn.microsoft.com/en-us/entra/architecture/security-operations-introduction
• Multi-Factor Authentication (MFA) – Adds an extra layer of security beyond passwords https://learn.microsoft.com/en-us/entra/identity/authentication/concept-mfa-howitworks
• Conditional Access – Enforces security policies based on user risk, location, and device https://www.cloudpartner.fi/?p=16831 and https://learn.microsoft.com/en-us/entra/identity/conditional-access/overview
• Privileged Identity Management (PIM) – Limits and manages high-risk access to critical resources https://www.cloudpartner.fi/?p=16863 and https://learn.microsoft.com/en-us/entra/id-governance/privileged-identity-management/pim-getting-started

🛡 Threat Protection and Security Monitoring

Azure integrates advanced security monitoring tools to detect and respond to threats in real time.

• Azure Disk Encryption – Uses BitLocker for Windows and dm-crypt for Linux VMs https://learn.microsoft.com/en-us/azure/virtual-machines/disk-encryption-overview
• Confidential Computing – Encrypts data while in use, ensuring end-to-end security https://learn.microsoft.com/en-us/azure/confidential-computing/overview

🌐 Network Security and Segmentation

Network security is critical in protecting Azure workloads from unauthorized access and attacks.

• Network Security Groups (NSGs) – Define security rules for traffic control https://learn.microsoft.com/en-us/azure/virtual-network/network-security-groups-overview
• Azure Virtual Network (VNet) Peering – Securely connects Azure resources https://learn.microsoft.com/en-us/azure/virtual-network/virtual-network-peering-overview
• Azure Web Application Firewall (WAF) – Protects applications from common web vulnerabilities https://learn.microsoft.com/en-us/azure/web-application-firewall/ag/ag-overview
• Azure Bastion – Provides secure RDP and SSH access to VMs without exposing public IPs https://learn.microsoft.com/en-us/azure/bastion/bastion-overview and the security baseline https://learn.microsoft.com/en-us/security/benchmark/azure/baselines/azure-bastion-security-baseline?toc=%2Fazure%2Fbastion%2FTOC.json

🏢 Security Compliance and Governance

Azure provides built-in tools to help organizations maintain regulatory compliance and enforce security best practices.

• Azure Policy – Automates compliance enforcement across cloud environments https://learn.microsoft.com/en-us/azure/governance/policy/overview
• Microsoft Purview – Manages data governance and regulatory compliance https://learn.microsoft.com/en-us/purview/purview and https://www.cloudpartner.fi/?p=15416
• Compliance Manager – Assesses compliance risks against industry standards https://www.cloudpartner.fi/?p=16424 and https://learn.microsoft.com/en-us/purview/compliance-manager
• Azure Security Benchmark – Offers best practice guidelines for securing Azure workloads https://learn.microsoft.com/en-us/security/benchmark/azure/baselines/azure-policy-security-baseline?toc=%2Fazure%2Fgovernance%2Fpolicy%2Ftoc.json&bc=%2Fazure%2Fgovernance%2Fpolicy%2Fbreadcrumb%2Ftoc.json
