Microsoft Entra ID is a cloud-based identity and access control service that provides security and functional capabilities. This Secure Configuration Baseline (SCB) provides specific policies to help secure Microsoft Entra ID.

The Secure Cloud Business Applications (SCuBA) project run by the Cybersecurity and Infrastructure Security Agency (CISA) provides guidance and capabilities to secure federal civilian executive branch (FCEB) agencies’ cloud business application environments and protect federal information that is created, accessed, shared, and stored in those environments.

The CISA SCuBA SCBs for M365 help secure federal information assets stored within M365 cloud business application environments through consistent, effective, and manageable security configurations. CISA created baselines tailored to the federal government’s threats and risk tolerance with the knowledge that every organization has different threat models and risk tolerance. Non-governmental organizations may also find value in applying these baselines to reduce risks.

If a third-party solution is used, then a P2 license is not required for the respective policies.
### Implementation

The following implementation instructions that reference the Microsoft Entra ID PIM service will vary if using a third-party PAM system instead.

# CISA M365 Security Configuration Baseline for Defender

Microsoft 365 (M365) Defender is a cloud-based enterprise defense suite that
coordinates prevention, detection, investigation, and response. This set
of tools and features are used to detect many types of attacks.

This baseline focuses on the features of Defender for Office 365, but
some settings are actually configured in the Microsoft Purview
compliance portal. However, for simplicity, both the
M365 Defender and Microsoft Purview compliance portal
items are contained in this baseline.

Generally, use of Microsoft Defender is not required by the baselines of
the core M365 products (Exchange Online, Teams, etc.). This baseline serves as
a guide should an agency elect to use Defender as their tool of choice. Please
note that some of the controls in the core baselines require the use of a
dedicated security tool, such as Defender.

In addition to these controls, agencies should consider using a cloud
access security broker to secure their environments as they adopt zero
trust principles.

The Secure Cloud Business Applications (SCuBA) project run by the Cybersecurity
and Infrastructure Security Agency (CISA) provides guidance and capabilities to
secure federal civilian executive branch (FCEB) agencies' cloud business
application environments and protect federal information that is created,
accessed, shared, and stored in those environments.

The CISA SCuBA SCBs for M365 help secure federal information assets stored within
M365 cloud business application environments through consistent, effective, and
manageable security configurations. CISA created baselines tailored to the federal
government's threats and risk tolerance with the knowledge that every organization
has different threat models and risk tolerance. Non-governmental organizations may
also find value in applying these baselines to reduce risks.
