What is Zero Trust architecture?

Zero Trust assumes breach and verifies every request. We implement verify explicitly, least privilege access and assume breach principles via Entra ID and Conditional Access.

How does Microsoft Defender for Cloud work?

Defender provides CSPM (Cloud Security Posture Management), threat protection for VMs, containers, SQL and more. Secure Score measures security level.

What is Azure Sentinel?

Azure Sentinel is cloud-native SIEM/SOAR. It collects logs from Azure, M365, on-premise, detects threats using AI and automates response via playbooks.

How do you handle identity management?

Entra ID (Azure AD) for SSO, MFA, Privileged Identity Management (PIM), Conditional Access policies and identity governance.

Do you support compliance audits?

Yes, we help with GDPR, ISO 27001, SOC 2, NIS2. Azure Compliance Manager provides assessment and action plans.

How do you protect data at-rest and in-transit?

TLS 1.3 for data in-transit, Azure Disk Encryption and Storage Service Encryption for data at-rest. Key Vault for key management.

What is network security in Azure?

NSG, Azure Firewall, WAF, Private Endpoints, DDoS Protection. We implement hub-spoke topology with central security.

How do you detect and respond to incidents?

Sentinel SIEM for detection, automated playbooks for response, 24/7 SOC monitoring and defined incident response procedures.

Do you support privileged access management?

Yes, Entra PIM for just-in-time elevated access, approval workflows and audit trail for all privileged operations.

How do you secure DevOps pipeline?

Azure DevOps security, secret scanning, dependency vulnerability checks, signed commits and secure artifact management.

What is Azure Policy?

Azure Policy enforces organizational standards - allowed regions, required tags, encryption requirements. Preventive and detective controls.

How do you handle container security?

Microsoft Defender for Containers, image scanning, runtime protection, network policies and pod security standards.

Do you support security for hybrid environments?

Yes, Azure Arc extends security to on-premise and multi-cloud. Defender for Servers protects non-Azure workloads too.

What security certifications do you have?

Team has Microsoft Security certifications, SC-200 (Security Operations), SC-300 (Identity) and AZ-500 (Azure Security).

Zero Trust architektura, threat detection a compliance frameworky pro enterprise security na Azure

Security best practices

Zero Trust architektura

Verify explicitly, use least privilege, assume breach. Každý request musí být autentizován a autorizován bez ohledu na source.

Defender for Cloud score

Sledujte Secure Score a systematicky řešte doporučení. Cílte na 80%+ pro production subscriptions.

Network micro-segmentation

NSG per-subnet, ASG pro aplikační skupiny, Private Endpoints pro PaaS služby. Zero public endpoints.

Identity-first security

Azure AD Conditional Access, MFA everywhere, PIM pro privileged roles. Passwordless authentication jako cíl.

SIEM/SOAR s Sentinel

Centralizujte security logy v Sentinel. Automation rules a playbooks pro automated response na incidenty.

DevSecOps pipeline

Security scanning v CI/CD: SAST, DAST, dependency scanning, container scanning. Shift-left security.

Čeho se vyvarovat

Security as afterthought

Security musí být součástí designu od začátku. Retrofit security je 10x dražší a méně efektivní.

Over-permissive RBAC

Owner/Contributor pro všechny je anti-pattern. Custom roles, least privilege, regular access reviews.

Ignorování alertů

Alert fatigue je reálné riziko. Tuněte alerty, prioritizujte, automatizujte response na known patterns.

Public endpoints na PaaS

Azure SQL, Storage, Key Vault – vše by mělo být za Private Endpoints. Public access = attack surface.

Azure Cloud Security — klíčová témata

Azure Cloud Security — Defender, Sentinel a Zero Trust

Komplexní zabezpečení Azure prostředí: CSPM, SIEM/SOAR, identity protection a network security podle Zero Trust modelu.
