5.Security

2.5.1 Overview

If your Kafka cluster has set security authentication, you need to set the corresponding security authentication information in EFAK.

• SASL/GSSAPI (Kerberos)

• SASL/PLAIN

• SASL/SCRAM-SHA-256

• SASL/OAUTHBEARER

• SSL

• CGROUPS (SASL & SSL)

2.5.2 Kerberos

EFAK system-config.properties file setting:

######################################
# kafka  sasl authenticate
######################################
cluster1.efak.sasl.enable=true
cluster1.efak.sasl.protocol=SASL_PLAINTEXT
cluster1.efak.sasl.mechanism=GSSAPI
cluster1.efak.sasl.jaas.config=com.sun.security.auth.module.Krb5LoginModule required useKeyTab=true storeKey=true keyTab="/etc/security/keytabs/kafka_client.keytab" principal="[e-mail]";
# make sure there is a local ticket cache "klist -l" to view
# cluster1.efak.sasl.jaas.config=com.sun.security.auth.module.Krb5LoginModule required useTicketCache=true renewTicket=true serviceName="kafka-eagle.org";
# if your kafka cluster doesn't require it, you don't need to set it up
# cluster1.efak.sasl.client.id=

2.5.3 PLAIN

EFAK system-config.properties file setting:

######################################
# kafka  sasl authenticate
######################################
cluster1.efak.sasl.enable=true
cluster1.efak.sasl.protocol=SASL_PLAINTEXT
cluster1.efak.sasl.mechanism=PLAIN
cluster1.efak.sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule required username="kafka" password="kafka-eagle";
# if your kafka cluster doesn't require it, you don't need to set it up
# cluster1.efak.sasl.client.id=

2.5.4 SCRAM-SHA-256

EFAK system-config.properties file setting:

######################################
# kafka  sasl authenticate
######################################
cluster1.efak.sasl.enable=true
cluster1.efak.sasl.protocol=SASL_PLAINTEXT
cluster1.efak.sasl.mechanism=SCRAM-SHA-256
cluster1.efak.sasl.jaas.config=org.apache.kafka.common.security.scram.ScramLoginModule required username="kafka" password="kafka-eagle";
# if your kafka cluster doesn't require it, you don't need to set it up
# cluster1.efak.sasl.client.id=

2.5.5 OAUTHBEARER

If you use this authentication, you need to make sure that your Kafka cluster version is after 2.x, EFAK system-config.properties file setting:

######################################
# kafka  sasl authenticate
######################################
cluster1.efak.sasl.enable=true
cluster1.efak.sasl.protocol=SASL_PLAINTEXT
cluster1.efak.sasl.mechanism=OAUTHBEARER
cluster1.efak.sasl.jaas.config=org.apache.kafka.common.security.oauthbearer.OAuthBearerLoginModule required unsecuredLoginStringClaim_sub="kafka-eagle";
# if your kafka cluster doesn't require it, you don't need to set it up
# cluster1.efak.sasl.client.id=

2.5.6 SSL

If you use this authentication(ssl), you need to make sure that your Kafka cluster version is after 2.x, EFAK system-config.properties file setting:

######################################
# kafka ssl authenticate
######################################
cluster3.efak.ssl.enable=true
cluster3.efak.ssl.protocol=SSL
# kafka server.properties "ssl.truststore.location" value
cluster3.efak.ssl.truststore.location=/data/kafka/ssl/certificates/kafka.truststore
# kafka server.properties "ssl.truststore.password" value
cluster3.efak.ssl.truststore.password=ke123456
# kafka server.properties "ssl.keystore.location" value
cluster3.efak.ssl.keystore.location=/data/kafka/ssl/certificates/kafka.keystore
# kafka server.properties "ssl.keystore.password" value
cluster3.efak.ssl.keystore.password=ke123456
# kafka server.properties "ssl.endpoint.identification.algorithm" value
cluster3.efak.ssl.endpoint.identification.algorithm=https
# kafka server.properties "ssl.key.password" value
cluster3.efak.ssl.key.password=ke123456

2.5.7 CGroups

When using permission authentication (such as SASL Or SSL), the user you are using only supports managing a limited number of kafka topics. You can enable the following properties:

# SASL
cluster1.efak.sasl.cgroup.enable=true
cluster1.efak.sasl.cgroup.topics=topic1,topic2,topic3
# SSL
cluster2.efak.ssl.cgroup.enable=true
cluster2.efak.ssl.cgroup.topics=topic4,topic5,topic6
