Behind the Scenes in Developing a Cassandra Password Validator

Stefan Miklosovic walks us through a new feature in Apache Cassandra:

Here’s the problem: while users have always had the ability to create whatever password they wanted in Cassandra–from straightforward to incredibly complex and everything in between–this ultimately created a noticeable security vulnerability.

While organizations might have internal processes for generating secure passwords that adhere to their own security policies, Cassandra itself did not have the means to enforce these standards. To make the security vulnerability worse, if a password initially met internal security guidelines, users could later downgrade their password to a less secure option simply by using “ALTER ROLE” statements.

Read on to see how CEP-24 helps with this. It looks like CEP-24 will be released in Apache Cassandra 5.1.
