Phishing protection for app registration

Phishing attacks on users are rising. There are countless possibilities for phishing attacks. One of them attempts to gain unauthorized access to the data via the app registration. If the attack is successful, no password change will lock the attacker out again. Auch die Multi-Faktor-Authentifizierung bietet keinen Schutz, da die App des Angreifers bereits zum Zugriff auf die Daten berechtigt ist. It’s time to restrict app registration and thus increase security against phishing.

Enable Microsoft Entra self-service password reset (SSPR) (SSPR)

Microsoft Entra self-service password reset (SSPR) allows users to change or reset the password on their own. It does not require support from the helpdesk.

To allow the user to change or reset the password, the following authentication methods are available for Microsoft Entra self-service password reset (SSPR):

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
