What is SASL mechanism plain?

What is SASL mechanism plain?

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. The username is used as the authenticated principal , which is used in authorization (such as ACLs).

What is the difference between SASL and 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.

Is SASL Plain secure?

The PLAIN SASL mechanism does not provide a security layer. The PLAIN mechanism should not be used without adequate data security protection as this mechanism affords no integrity or confidentiality protections itself.

What is SASL in Kafka?

Kafka supports using Simple Authentication and Security Layer (SASL) to authenticate producers and consumers. Vertica supports using the SASL_PLAINTEXT and SASL_SSL protocols with the following authentication mechanisms: PLAIN. SCRAM-SHA-256.

What is SASL used for?

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 means SASL?

Simple Authentication and Security Layer
Introduction The Simple Authentication and Security Layer (SASL) is a framework for providing authentication and data security services in connection-oriented protocols via replaceable mechanisms. SASL provides a structured interface between protocols and mechanisms.

What does SASL?

Simple Authentication and Security Layer (SASL) is a framework for authentication and data security in Internet protocols. It decouples authentication mechanisms from application protocols, in theory allowing any authentication mechanism supported by SASL to be used in any application protocol that uses SASL.

What does SASL stand for?

Simple Authentication Security Layer
Introduction to Simple Authentication Security Layer (SASL) SASL provides developers of applications and shared libraries with mechanisms for authentication, data integrity-checking, and encryption.

What port does SASL use?

SASL provides several mechanisms to increase the security of an LDAP connection, including user authentication, anti-tampering (message signing), and confidentiality (encryption). SASL is a communication layer that operates within LDAP on the default AD data ports (TCP port 389 and TCP port 3268).

How do I enable SASL?

SASL configuration for Kafka brokers

1. Select one or more supported mechanisms to enable in the broker.
2. Add a JAAS config file for the selected mechanisms as described in the examples for setting up GSSAPI (Kerberos) or PLAIN.
3. Pass the JAAS config file location as JVM parameter to each Kafka broker.

What is Kafka SASL JAAS config?

Kafka uses the Java Authentication and Authorization Service (JAAS) for SASL configuration. You must provide JAAS configurations for all SASL authentication mechanisms. Pass a static JAAS configuration file into the JVM using the java. security.

What is SASL connection?

How is the plain mechanism used in SASL?

Abstract This document defines a simple clear-text user/password Simple Authentication and Security Layer (SASL) mechanism called the PLAIN mechanism. The PLAIN mechanism is intended to be used, in combination with data confidentiality services provided by a lower layer, in protocols that lack a simple password authentication command.

Is there a secure way to use SASL?

As we discussed earlier, SASL is a framework capable of supporting secure communication beyond just authentication. However, this is only possible if the underlying mechanism supports it. Firstly, let’s first check if we have been able to negotiate a secure communication:

How is the authorization ID used in SASL?

The authorization ID ( userid) is used to check whether the user is allowed to use a particular option. The SASL client application and SASL server application negotiate a common SASL mechanism and security level. Typically, the SASL server application sends its list of acceptable authentication mechanisms to the client.

Which is the default implementation of SASL / plain in Kafka?

The default implementation of SASL/PLAIN in Kafka specifies usernames and passwords in the JAAS configuration file.
