Microsoft Entra Private Access: secure access to internal resources and cloud services without VPN

Microsoft Entra Private Access gives users secure access to the internal network and cloud-based services from anywhere in the world. Setting up and maintaining (complex) VPN connections is now a thing of the past. Microsoft Entra Private Access is part of Microsoft Global Secure Access, which includes a range of identity and network access security products. The service is based on the SASE framework (Secure Access Service Edge), which combines WAN functions and zero-trust network access (ZTNA) in a cloud-based platform.

Block Legacy Authentication with Azure AD Conditional Access

Widely used legacy authentication protocols such as POP, SMTP, IMAP or MAPI are now a serious security vulnerability and thus very popular with attackers.

The numbers on legacy authentication from one analysis are stark:

  • More than 99 percent of password spray attacks use legacy authentication protocols
  • More than 97 percent of credential stuffing attacks use legacy authentication
  • Azure AD accounts in organizations that have disabled legacy authentication experience 67 percent fewer compromises than those where legacy authentication is enabled

Multi-factor authentication method analysis

For a security audit, it is necessary to check which multi-factor authentication method is enabled for each individual user in the Microsoft tenant.

The guide can also be used to make users aware of a multi-factor authentication method that may be more convenient for them than they currently have enabled.

The following are possible multi-factor authentication methods.:

  • Mobile App (Microsoft Authenticator)
  • Text message
  • Phone call

App Password for Multi-Factor Authentication

Apps that do not support two-step verification can cause problems after enabling multi-factor authentication (MFA). These apps, also called non-browser apps, can no longer be used after multi-factor authentication is enabled.

To continue to use these apps securely, an App Password can be used for authentication. An App Password is a secure, randomly generated password that can be used instead of the regular password for an app.

User guide: Enabling multi-factor authentication

Enabling Multi-Factor Authentication (MFA) significantly increases the security of user accounts when accessing Microsoft Azure and Microsoft 365 online services. The following user guide will help to set up one of the following authentication methods.

Three variants are available to authenticate with the second factor:

  • Variant 1: Authentication via mobile app on smartphone (recommended)
  • Variant 2: Authentication via SMS
  • Variant 3: Authentication via phone call
