Publicly available Tenable .audit scripts

This is most likely a slowpoke news, but I just found out that Tenable .audit files with formalized Compliance Management checks are publicly available and can be downloaded without any registration. ?? However, you must accept the looooong license agreement.

Tenable .audit script

So, I have two (completely theoretical!) questions ?:

  1. What if someone supports the .audit format in some compliance tool and gives the end user an ability to use this content by Tenable to asses their systems? Will it be fair and legal?
  2. What if someone uses this content as a source of inspiration for his own content, for example, in a form of OVAL/SCAP or some scripts? Will it be fair and legal?

.audit-based Compliance Management in Nessus

In this post I will briefly describe how Nessus .audit-based Compliance Management works, why I like it, what could be improved and why I suppose Tenable won’t do it soon. 😉

Nessus compliance checks are mainly presented in a form of special .audit scripts. This scripting language is very different from familiar NASL (Nessus Attack Scripting Language).

Basically, it is a collection of universal checks for various objects (e.g. existence of the line or parameter in the file, access permissions of the file,  service status, etc.). Of course, nowadays Сompliance Management is not only about Operating System and software (mis)configuration. We have different network devices, databases, cloud services, etc. but originally it was the main case.

By combining the universal checks  any requirement of low-level configuration standard (CIS, DISA, etc.) can be implemented. The similar principles are used in OVAL/SCAP content.

ZeroNights16: Enterprise Vulnerability Management

17-18 November I was at the great event  Zero Nights security conference in Moscow. For the first time as a speaker. Being a part of such famous and prestigious security event was very exciting. There were three of us, Ekaterina Pukhareva, Alex Smirnoff and me, and only 20 minutes available for all. I was talking mainly about VM solution problems and custom reporting/ticketing, Ekaterina shared some experience in using Tenable SecurityCenter for Vulnerability and Compliance management, and Alex was talking mainly about Asset and Risk Management.

Presentation was recorded and some time later video will be available on YouTube. However, I suppose audio will be only in Russian not earlier than February 2017. So I think it will be a much more useful to share some points of the presentation right now. Lucky here I don’t have any time restrictions. =)

The first thing to say about Vulnerability Scanners and Vulnerability Management product is that there are plenty of them. On this picture I mentioned some of the products/vendors.

Vulnerability Scanners and Vendors

Some of them are highly specialized, like ErpScan for SAP, others are universal. Some of them are presented globally: Tenable Nessus / SecurityCenter, Rapid 7 Nexpose, Qualys, F-Secure etc., others are known mainly in Russia: Positivie Technologies Maxpatrol, Altx-Soft RedCheck, Echelon Scaner-VS. Some products are expansive, some of them not and even have versions available for free: OpenVAS, SecPod Saner Personal, Altx-Soft ComplianceCheck, Qualys SSL labsHigh-Tech Bridge SSL Server Security Test, etc.

In my opinion the main problems of VM solutions are expansiveness and low reliability of the scan results.
