Protect user and device access
Protecting access to your Office 365 data and services is crucial to defending against cyber-attacks and guarding against data loss. The same protections can be applied to other SaaS applications in your environment and even to on-premises applications published with Azure Active Directory Application Proxy.
Step 1: Review recommendations
Recommended capabilities for protecting identities and devices that access Office 365, other SaaS services, and on-premises applications published with Azure AD Application Proxy.
Step 2: Protect administrator accounts and access
The administrative accounts you use to administer your Office 365 environment include elevated privileges. These are valuable targets for hackers and cyber criminals.
Begin by using administrator accounts only for administration. Admins should have a separate user account for regular, non-administrative use and only use their administrative account when necessary to complete a task associated with their job function.
Protect your administrator accounts with multi-factor authentication and conditional access. For more information, see Protecting administrator accounts.
Next, configure privileged access management in Office 365. Privileged access management allows granular access control over privileged admin tasks in Office 365. It can help protect your organization from breaches that may use existing privileged admin accounts with standing access to sensitive data or access to critical configuration settings.
Another top recommendation is to use workstations specifically configured for administrative work. These are dedicated devices that are only used for administrative tasks. See Securing privileged access.
Finally, you can mitigate the impact of inadvertent lack of administrative access by creating two or more emergency access accounts in your tenant. See Manage emergency access accounts in Azure AD.
Step 3: Configure recommended identity and device access policies
Multi-factor authentication (MFA) and conditional access policies are powerful tools for mitigating against compromised accounts and unauthorized access. We recommend implementing a set of policies that have been tested together. For more information, including deployment steps, see Identity and device access configurations.
These policies implement the following capabilities:
- Mult-factor authentication
- Conditional access
- Intune app protection (app and data protection for devices)
- Intune device compliance
- Azure AD Identity Protection
Implemetning Intune device compliance requires device enrollment. Managing devices allows you to ensure that they are healthy and compliant before allowing them access to resources in your environment. See Enroll devices for management in Intune
Step 4: Configure SharePoint device access policies
Microsoft recommends you protect content in SharePoint sites with sensitive and highly-regulated content with device access controls. For more information, see Policy recommendations for securing SharePoint sites and files.
