Cis Cassandra5 1.4

Ensure latest version of Cassandra is installed (Automated)

Profile Applicability

• Level 1 - Cassandra on Linux

Description

The Cassandra installation version, along with the patches, should be the most recent that is compatible with organizational needs. When obtaining and installing software packages (typically via apt-get or you can compile the source code), it's imperative that packages (or the source code, tarball) are sourced only from valid and authorized repositories.

For Cassandra, a short list of valid repositories may include:

• The official apache cassandra website: http://cassandra.apache.org/
• DataStax Enterprise: https://www.datastax.com/

Rationale

Using the most recent version of Cassandra can help limit the possibilities for vulnerabilities in the software, the installation version applied during setup should be established according to the needs of the organization. Ensure you are using a release that is covered by a level of support which includes regular updates to address vulnerabilities.

Impact

None

Audit Procedure

To verify the version of Cassandra you have installed:

cassandra -v

4.0.3 (a/o 2022-03-29)

Released on 2022-02-17 Maintained until 4.3.0 release (May-July 2024)

If an old/unsupported version of Cassandra is installed this is a finding.
