Chapter 14

1. There is no such thing as perfectly secure software, and mistakes are frequently made. Luckily, both the Keycloak team and its community are continuously looking for vulnerabilities and are continuously fixing any issues they find. If you don’t update Keycloak, you will not receive these fixes, but anyone wanting to attack your Keycloak server will.
2. Keycloak stores a lot of sensitive data in the database, which is valuable information to an attacker. If an attacker gains write access to the database, the attacker can make changes that could allow the attacker to gain access to any application secured by Keycloak.
3. No; only relying on a web application firewall is not a good idea. You will want to enable strong authentication, as well as provide a good level of security within the application itself.
