As more organizations continue to move towards a cloud-based environment, many are utilizing Docker containers to deploy systems and applications quickly without additional overhead. Containers include a lightweight base operating system that allows organizations to migrate and scale across different systems easily. Unfortunately, Docker containers are subject to security risks, as applications deployed within containers can contain exploitable vulnerabilities. The Center for Internet Security (CIS) is an organization that works with security experts to develop a set of 'best practice' security standards designed to harden operating systems and applications. These report templates provide a high-level overview of results gathered from CIS compliance scans using the CIS Docker Benchmarks.
Tenable Network Security has been certified by CIS to perform a wide variety of platform and application audits based on the best practice consensus benchmarks developed by CIS. Tenable submits example test cases for all of the criteria within each unique benchmark, and then submits our results to CIS personnel for official certification. Tenable has developed audit files based on the CIS Docker Benchmarks, which have been approved and certified by CIS staff members.
When performing managed scans with Tenable.sc, some CIS audits require additional patch audits and vulnerability checks. Any additional requirements for completing an audit using the CIS Docker Benchmarks will be included within the audit file description text. In some cases, multiple scans may be required to be performed, as Tenable provides both Level 1 and Level 2 audit checks. Level 1 checks provide minimum settings recommendations, and are generally considered safe to apply to most systems. Level 2 checks include recommendations for complex or highly secure environments, and can lead to reduced functionality of Docker containers.
In order to perform audit scans with Tenable.sc, CIS Docker Benchmark audit files must be uploaded first. Next, the appropriate credentials must be added, after which a scan policy can be created. Finally, a scan can be scheduled. As part of the post scan jobs, the 'Auto-Run Reports' can be enabled automatically, running this report on the data collected using the appropriate audit file. Using these benchmarks will help to assess the effectiveness of existing security controls on Docker containers, and provide the critical information needed to improve an organization's security posture.
The reports are available in the Tenable.sc Feed, a comprehensive collection of dashboards, reports, Assurance Report Cards, and assets. The reports can be easily located in the Tenable.sc Feed under the category Compliance & Configuration Assessment. The report requirements are:
- Tenable.sc 5.2.0
- Nessus 8.5.1
- CIS Audit Files for Docker systems are required, and the files required for each template are listed below with their respective templates.
Tenable's Tenable.sc helps organizations measure and communicate results with many compliance standards using the CIS Benchmarks. By frequently scanning systems, Tenable.sc will measure compliance in real-time, providing a security posture assessment of Docker containers throughout the enterprise. By default, Tenable.sc comes with over 200 audit files for CIS and more than 400 audit files overall. By prioritizing remediation actions of misconfigured systems, the organization can maximize their investment in compliance reporting and system hardening efforts. With more supported technologies than any other vendor, organizations will obtain the most comprehensive view of the network, and the intelligence needed to assess the enterprise against CIS compliance standards.
