=== SSL/HTTPS Requirement
|
|
|
|
If you do not use SSL/HTTPS for all communication between the {{book.project.name}} auth server and the clients it secures, you will be very vulnerable to man in the middle attacks.
|
|
OAuth 2.0/OpenID Connect uses access tokens for security.
|
|
Without SSL/HTTPS, attackers can sniff your network and obtain an access token.
|
|
Once they have an access token they can do any operation that the token has been given permission for.
|
|
|
|
{{book.project.name}} has <<fake/../../realms/ssl.adoc#_ssl_modes,three modes for SSL/HTTPS>>.
|
|
SSL can be hard to set up, so out of the box, {{book.project.name}} allows non-HTTPS communication over private IP addresses like
|
|
localhost, 192.168.x.x, and other private IP addresses.
|
|
In production, you should make sure SSL is enabled and required across the board.
|
|
|
|
On the adapter/client side, {{book.project.name}} allows you to turn off the SSL trust manager.
|
|
The trust manager ensures identity the client is talking to.
|
|
It checks the DNS domain name against the server's certificate.
|
|
In production you should make sure that each of your client adapters is configured to use a truststore.
|
|
Otherwise you are vulnerable to DNS man in the middle attacks.
