The Invoke-M365SecurityAudit cmdlet performs a comprehensive security audit based on the specified parameters. It allows auditing of various configurations and settings within a Microsoft 365 environment, such as compliance with CIS benchmarks.
.PARAMETER TenantAdminUrl
The URL of the tenant admin. This parameter is mandatory.
.PARAMETER DomainName
The domain name of the Microsoft 365 environment. This parameter is mandatory.
.PARAMETER M365DomainForPWPolicyTest
The domain name of the Microsoft 365 environment to test. This parameter is not mandatory and by default it will pass/fail all found domains as a group if a specific domain is not specified.
.PARAMETER ELevel
Specifies the E-Level (E3 or E5) for the audit. This parameter is optional and can be combined with the ProfileLevel parameter.
