Vulnerability Management Product Comparisons (October 2019)

Here I combined two posts [1.2] from my telegram channel about comparisons of Vulnerability Management products that were recently published in October 2019. One of them was more marketing, published by Forrester, the other was more technical and published by Principled Technologies.

Vulnerability Management Product Comparisons (October 2019)

I had some questions for both of them. It’s also great that the Forrester report made Qualys, Tenable and Rapid7 leaders and Principled Technologies reviewed the Knowledge Bases of the same three vendors.

Let’s start with Forrester.

Dante SOCKS5 server with authentication

It’s not so obvious that socks servers with authentication are a necessary thing.

  1. You can run a “local socks service” simply by connecting to a remote host via ssh (with -D <port>)
  2. Most of software products, that support socks, don’t support socks servers with authentication

The last fact I find very unfortunate, because using socks without having to monitor ssh connection is much more comfortable. But if the software actually supports socks with authentication you can try Dante server.

Here’s how to install and configure it in CentOS 7.

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?

The most magnificent thing about Vulnerabilities and who is behind the magic

What I like the most about software vulnerabilities is how “vulnerability”, as a quality of a real object (and the computer program is real), literally appears from nothing.

The most magnificent thing about Vulnerabilities and who is behind the magic

Let’s say we have a fully updated server. We turn it off, lock it in a safe and forget about it for half a year. Six months later, we get it, turn it on. It is the same and works absolutely the same. But now it is also exposed to dozens of critical vulnerabilities that, with some (un)luck, can be exploited by any script kiddie. New important characteristic of the material object appeared from nowhere, isn’t this magnificent? 🤩

PHDays 9: new methods of Vulnerability Prioritization in Vulnerability Management products

On May 21, I spoke at the PHDays 9 conference. I talked about new methods of Vulnerability Prioritization in the products of Vulnerability Management vendors.

PHDays9 new ways of prioritizing vulnerabilities

During my 15 minutes time slot I defined the problems that this new technology has to solve, showed why these problems could NOT be solved using existing frameworks (CVSS), described what we currently have on the market and, as usual, criticized VM vendors and theirs solutions a little bit. 🙂

Code IB 2019: Vulnerability Management Masterclass

On March 29, I held one hour master class “HOW to avoid excessive formalism in Vulnerability Management process” at Code IB Profi 2019. Everything went quite well and I’ve got 88% positive ratings. Not bad result ^_^.

The main feature of the conference was a very special audience. The only way to visit this event was to buy a real ticket (there were no promotional codes, invites, free tickets from sponsors, etc.). So, the people who came were really interested in the content. Target audience: CISO, their deputies, leading experts from all industries. The whole event was up to 200 people, it lasted for 2 days with 4 threads of masterclasses.

This year organizers decided that titles of all masterclasses should start with “How to” (to keep them practical) and there should be checklists for each masterclass as a handout. I am going to translate my checklist Into English and publish it in this blog soon.

In fact, there were 2 masterclasses on Vulnerability Management at the conference! The second was held by Lev Paley. However, our content did not intersect: I spoke mostly about technical stuff (and I criticized VM vendors as usual), and he spoke mainly about the organizational part and high-level processes.

Vulnerability Management vendors and Vulnerability Remediation problems

It’s not a secret, that Vulnerability Management vendors don’t pay much attention to the actual process of fixing vulnerabilities, that they detect in the infrastructure (Vulnerability Remediation). Although it seems to be the main goal of VM products: to make vulnerabilities fixed and whole IT infrastructure more secure, right?

In fact, most of VM vendors see their job in finding a potential problem and providing a link to the Software Vendor’s website page with the remediation description. How exactly the remediation will be done is not their business.

Vulnerability Management vendors and Vulnerability Remediation

The reason is clear. Remediation is a painful topic and it’s difficult to sell it as a ready-made solution. And even when Vulnerability Vendors try to sell it this way, it turns out pretty ugly and does not really work. Mainly because the Remediation feature is sold to the Security Team, and the IT Team will have to use it.
