CIS 1.2.2 — Ensure the latest software package is installed

Profile Applicability

Level 1 - Webserver
Level 1 - Proxy
Level 1 - Loadbalancer

Description

As new security vulnerabilities are discovered, the corresponding fixes are implemented by your NGINX software package provider. Installing the latest software version ensures these fixes are available on your system.

Rationale

Up-to-date software provides the best possible protection against exploitation of security vulnerabilities, such as the execution of malicious code.

Impact

Updating the NGINX package requires a service reload or restart to apply the changes. This may cause a brief interruption or configuration errors if the new version deprecates existing syntax.

Audit Procedure

To verify your NGINX package is up to date, run the following command (example):

Redhat:

dnf info nginx

Remediation

To install the latest NGINX package, run the following command (example):

Redhat:

dnf update nginx -y

Default Value

Not applicable. The installed version depends on the configured repository and when the last update was performed.

Additional Information

Package update and installation commands are based on Red Hat Enterprise Linux 9. If using a different Linux distribution, please substitute with the appropriate command(s) and consider your organization patch management policy.
