TMA-CASSANDRA-3.5
Ensure that Cassandra only listens for network connections on authorized interfaces
Beschreibung
When listen_address is blank and listen_interface is commented out, this will be set automatically by InetAddress.getLocalHost(). Presuming the node is configured correctly, e.g. hostname, name resolution, etc., this will configure the node to use the address associated with the hostname. The listen_address must not be set to 0.0.0.0.
So wird geprüft
Prüfmethode: Manuelle Prüfung
Diese Empfehlung kann nicht automatisch geprüft werden. Ein Scan führt sie mit diesen Anweisungen auf, wenn Sie --include-manual übergeben.
Run grep -nE "^(listen_address|listen_interface|rpc_address|rpc_interface):" /etc/cassandra/cassandra.yaml. Only one of listen_address/listen_interface may be set, it must name an authorised address or interface, and listen_address must not be 0.0.0.0. Any other value is a finding.
So wird behoben
Behebungsmethode: Anleitung oder Infrastruktur-Patch
Set the listen_address or listen_interface, not both, in the cassandra.yaml to an authorized address or interface.
