What is SASL in ZooKeeper?
This document describes the integration between ZooKeeper and the SASL (Simple Authentication and Security Layer). This contains the details to configure ZooKeeper in secure mode. ZooKeeper supports: Client-Server mutual authentication.
What is ACL in ZooKeeper?
ZooKeeper uses ACLs to control access to its znodes (the data nodes of a ZooKeeper data tree). The ACL implementation is quite similar to UNIX file access permissions: it employs permission bits to allow/disallow various operations against a node and the scope to which the bits apply.
What is the latest version of ZooKeeper?
The stable version of ZooKeeper is 3.6. x and the current version is 3.7.
What is ZooKeeper used for?
ZooKeeper is an open source Apache project that provides a centralized service for providing configuration information, naming, synchronization and group services over large clusters in distributed systems. The goal is to make these systems easier to manage with improved, more reliable propagation of changes.
Is SASL secure?
SASL provides developers of applications and shared libraries with mechanisms for authentication, data integrity-checking, and encryption. SASL enables the developer to code to a generic API. This approach avoids dependencies on specific mechanisms.
What is SASL scram?
Salted Challenge Response Authentication Mechanism (SCRAM), or SASL/SCRAM, is a family of SASL mechanisms that addresses the security concerns with traditional mechanisms that perform username/password authentication like PLAIN. Apache Kafka® supports SCRAM-SHA-256 and SCRAM-SHA-512 .
What is ACL and SSL?
The ACL Connector for Analytics Exchange supports Secure Sockets Layer (SSL) encryption on the connections between client machines and AX Server. If SSL is enabled, the connector uses OpenSSL to encrypt all data moving across the network connections between client machines and the server.
How does kafka’s ACL work?
Kafka ACLs control which principals can perform operations on Kafka resources. Kafka brokers can use ZooKeeper ACLs by enabling ZooKeeper Security ( zookeeper. set. acl=true ) for the broker configuration.

Is ZooKeeper still used?
Currently, Apache Kafka® uses Apache ZooKeeper™ to store its metadata. Data such as the location of partitions and the configuration of topics are stored outside of Kafka itself, in a separate ZooKeeper cluster. In 2019, we outlined a plan to break this dependency and bring metadata management into Kafka itself.
How does SASL authentication work?
SASL uses two important identifiers for users. The authentication ID (authid) is the user ID for authenticating the user. The authentication ID grants the user access to a system. The authorization ID (userid) is used to check whether the user is allowed to use a particular option.
Is SASL the same as SSL?
An obvious difference between SSL and SASL is that SASL allows you to select different mechanisms to authenticate the client while SSL is kind of binded to do authentication based on certificate. In SASL, you can choose to use GSSAPI, Kerberos, NTLM, etc.
How does SCRAM authentication work?
Using cryptographic hashing techniques, a client can prove to a server that the user knows a secret derived from the user’s password without sending the password itself. The server can prove to the client that it knows a secret derived from the user’s password also without having to send the actual password.
What is SASL in kafka?
SASL/PLAIN Overview. PLAIN, or SASL/PLAIN, is a simple username/password authentication mechanism that is typically used with TLS for encryption to implement secure authentication. Apache Kafka® supports a default implementation for SASL/PLAIN, which can be extended for production use.
How do I find my zookeeper ACL?
You can access Zookeeper using the zookeeper-shell.sh script. There is a znode called kafka-acl where information about ACLs for group, topic, cluster and so on are stored. You can list for example information about ACLs on topics ls /kafka-acl/Topic .
