The dos.yaml is intended to protect your app from Denial of Service (DOS) attacks or similar forms of abuse. It is mostly used for blocking / blacklisting IP addresses and networks. The App Engine firewall, however, allows you to both block and allow plus more features like better security and being able to set rules based on specific geographies, among others.
In fact, per this article <https://cloud.google.com/appengine/docs/standard/python/config/dos>: Do not use this service > <https://cloud.google.com/appengine/docs/standard/python/config/dos> (DoS > Protection) for security because some requests from blacklisted users can > still get through to your application. This service is designed for > quantitative abuse prevention, such as preventing DoS attacks, only. > You should instead use the App Engine firewall > <https://cloud.google.com/appengine/docs/standard/python/creating-firewalls> > for reliable protection as well as the improved features. > -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
