​If implemented and managed correctly, the Palo Alto Networks Next-Generation FireWall is one of the few security solutions that can truly protect enterprises from modern cyber threats without negatively affecting their operation. We have put our over 10 years’ experience in working with Palo Alto Networks together and compiled this list of Best Practices to help you to secure your network by leveraging the full potential of your Palo Alto Networks Next-Generation FireWall. Besides our own, it incorporates security best practices recommended by Palo Alto Networks "BPA" as well as the Center for Internet Security "CIS Controls".

Update 29.06.2020 - Mitigate SAML Bypass Vulnerability without upgrade (CVE-2020-2021) - This video explains how to securely set up SAML authentication end-to-end against Office 365 Azure AD. The critical element which explains how to set up certificate validation of the SAML Identity Provider starts at 29:35. With this configuration, there is no immediate need to upgrade the FireWall, although an upgrade should always be considered. It also fixes the commit error "Validate Identity Provider Certificate is checked but no Certificate Profile is provided authentication-profile"

Being able to authenticate your GlobalProtect or Prisma Access remote workers against Office 365 is very convenient as it provides a seamless single sign-on experience to the user. Of course its great from a security point of view as well, because you can use the integrated dual factor authentication that comes with Office 365.
But of course in order to authenticate against Office 365 you cannot use classical protocols like LDAP or Radius, instead you need SAML. Luckily, both Microsoft and Palo Alto Networks have made the integration very simple, and in this video we will show you the configuration end-to-end with all the tips and tricks you need to know to make to work.

Update 30.6.2020 - at around 5:40 in the video I'm mentioning Microsoft's misleading example for using wildcards in the identifier URL. While wildcards are not supported in standard marketplace app, they can be used in the manifest file of the enterprise app. This is tremendously useful for usage on Prisma Access. Thanks to @Marc Barten for providing this information.

With this powershell script you can add multiple identifier to the Azure AD Enterprise application as shown in the video.
