In today’s dynamic IT environment, managing and securing applications is a critical task for businesses. With hundreds of applications in use, ensuring proper inventory and control is essential to mitigate security risks. This article explores a phased approach to secure application management within Microsoft 365, aligning with the CIS Controls framework.
Phase 1: Inventory and Discovery
Start by identifying all applications in use across your organization. Use PowerShell commands to extract a list of installed applications:
Get-WmiObject -Class Win32_Product | Select-Object -Property Name, Version
For cloud-based applications, leverage Microsoft 365’s built-in tools to monitor and audit app usage:
Get-MsolServicePrincipal | Select-Object DisplayName, AppId
Phase 2: Risk Assessment
Evaluate the security risks associated with each application. Use the following command to check for outdated software:
sudo apt list --upgradable
For Windows systems, use:
Get-HotFix | Sort-Object InstalledOn -Descending | Select-Object HotFixID, InstalledOn
Phase 3: Access Control and Permissions
Implement strict access controls using Microsoft 365’s role-based access control (RBAC). Use PowerShell to manage permissions:
Add-MsolRoleMember -RoleName "Global Administrator" -RoleMemberEmailAddress [email protected]
Phase 4: Monitoring and Auditing
Continuously monitor application usage and detect anomalies. Use Azure Log Analytics to query logs:
[kusto]
AzureActivity
| where OperationName == “Create role assignment”
| project TimeGenerated, Caller, OperationName
[/kusto]
Phase 5: Incident Response
Prepare for potential breaches by setting up automated incident response workflows. Use Azure Sentinel to create playbooks:
New-AzSentinelIncident -ResourceGroupName "MyResourceGroup" -WorkspaceName "MyWorkspace" -IncidentName "AppCompromise"
What Undercode Say
Secure application management is a cornerstone of modern cybersecurity strategies. By following a phased approach, organizations can effectively mitigate risks associated with application sprawl. Leveraging tools like Microsoft 365, PowerShell, and Azure Sentinel ensures a robust defense against potential threats. Regularly updating software, enforcing strict access controls, and monitoring usage are critical steps in maintaining a secure IT environment. For further reading, explore the CIS Controls framework and Microsoft’s official documentation on application management.
