[ https://issues.jboss.org/browse/WFLY-2653?page=com.atlassian.jira.plugin.... ] Aleksandar Kostadinov updated WFLY-2653: ---------------------------------------- Description: At the moment I don't see any way to restrict allowed cipher suites for the https listener. {CODE} [standalone@localhost:9990 /] /core-service=management/security-realm=HttpsRealm:read-resource(recursive=true, include-defaults=true) { "outcome" => "success", "result" => { "map-groups-to-roles" => true, "authentication" => undefined, "authorization" => undefined, "plug-in" => undefined, "server-identity" => {"ssl" => { "alias" => undefined, "key-password" => undefined, "keystore-password" => "changeit", "keystore-path" => "localhost.keystore", "keystore-relative-to" => "jboss.server.config.dir", "protocol" => "TLS" }} } } [standalone@localhost:9990 /] /subsystem=undertow/server=default-server:read-resource(recursive=true, include-defaults=true) { "outcome" => "success", "result" => { <...> "https-listener" => {"https" => { "allow-encoded-slash" => false, "always-set-keep-alive" => true, "buffer-pipelined-data" => true, "buffer-pool" => "default", "decode-url" => true, "enabled" => true, "max-cookies" => 200, "max-header-size" => 51200, "max-headers" => 200, "max-parameters" => 1000, "max-post-size" => 10485760L, "security-realm" => "ApplicationRealm", "socket-binding" => "https", "url-charset" => "UTF-8", "verify-client" => "NOT_REQUESTED", "worker" => "default" }} } } {CODE} I have tested that default cipher suites used are pretty sane except RC4-SHA and RC4-MD5. Below is full list. But I think it is important for users to be able to support more or less ciphers depending on their environment and requirements. We also need good secure default settings IMO excluding the above mentioned two ciphers.

The minimum IMO is to have the `cipher-suite` attribute exposed like in jboss-web ssl configuration. It would be real nice if the attribute supports also filter by string. For example if user puts something like "ALL:!MD5:!DHA" that could filter out all MD5 and DH anonymous based suites. Would be something like `man ciphers`. The latter will allow for easily setting secure defaults that work across different JVMs because exact cipher names differ slightly across different JVMs. Otherwise we may need a separate list for each JVM. But that's perhaps more relevant for the product side. -- This message is automatically generated by JIRA.
