CIS Linux and Unix Benchmark Reports

While the majority of hosts on most networks are Windows Workstations, much of the infrastructure and server based systems are comprised of Linux and Unix operating systems. 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. Even vigilant system administrators struggle to maintain hardened systems across a hybrid system environment. Using Tenable.sc and the CIS benchmark guidelines provides an effect mechanism to audit systems against accepted best practices. These report templates provide a high-level view of compliance results based on the CIS Linux and Unix Benchmark Guidelines.

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. One of these policies developed by Tenable includes the CIS Linux & Unix benchmarks, which has been approved and certified by CIS staff members.  These report templates focus on the following operating systems:

• Amazon Linux
• Debian
• FreeBSD
• HP-UX
• Oracle Solaris
• SuSE Linux
• Ubuntu

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 Linux & Unix 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 setting 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 key systems or applications.

When performing audit scans with Tenable.sc, audit files related to the CIS Linux & Unix benchmarks must first be uploaded to Tenable.sc. 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, 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 Linux & Unix are required, and the files required for each template are listed below with their respective templates.

System administrators are tasked with maintaining a high level of expertise for hybrid system environments, which includes hardening several different distributions of Linux and Unix, along with many other operating systems. Using the CIS Benchmarks and Tenable.sc helps to measure and identify problem areas for system administrators to focus their efforts. By default, Tenable.sc comes with over 200 audit files for CIS and more than 400 audit files overall, which supports the security operations team in performing audits on many system types and applications. By prioritizing remediation actions for misconfigured systems, the organization can maximize their investment in compliance reporting and system hardening efforts. Tenable.sc delivers comprehensive security solutions that provide continuous visibility and critical context, enabling decisive actions to protect the organization.
