One key concern is publicly exposed storage accounts where files or containers can be accessed without proper authentication. These should be set to private with access provided through signed URLs. Overprivileged users in Azure Penetration Tests also pose a challenge. Owner access at resource level, granting users overarching control, enables unrestricted compromise. Follow the principle of least privilege and leverage Privileged Identity Management (PIM).
Other Azure clients also commonly mismanage access to Azure Key Vaults by overly broad access policy. Use strict access policies and enable access logging. Network Security Groups (NSGs) with unrestricted inbound rules let would-be attackers locate and exploit the services. IP and service-type restrictions for inbound rules should be applied.
Lack of effective monitoring also means threats often go unnoticed. Use proactive monitoring by turning on the Azure Activity log, setting up Diagnostic Setting, and monitoring unusual activities with Azure Sentinel.
Fixing these issues is simply a matter of better role-based access control and configuration management. Regular pentesting aids in discovering these risks early while maintaining the Azure infrastructure’s resilience and security.
