Guinea Pig and Vulnerability Management products

Guinea Pig and Vulnerability Management products. IMHO, security vendors use the term “Vulnerability Management” extremely inaccurate. Like a guinea pig, which is not a pig and is not related to Guinea, the current Vulnerability Management products are not about the actual (practically exploitable) vulnerabilities and not really about the management.

Guinea Pig and Vulnerability Management

Vulnerability should mean something solid and reliable, something that can be practically used by a malicious attacker or penetration tester.

When (so-called) Vulnerability Management vendors start working with indirect information from third-party about potential vulnerabilities in the software, that were possibly exploited by someone in some unknown conditions, or simply distance from responsibility: “we just provide information from the software vendor; software vendor knows better about the vulnerabilities in his own products”, it’s all falling into to the area of fortune telling and counting angels on the head of a pin.

Hardcore process of identifying weaknesses that real-life attackers can use moves to a boring compliance. For example, as PCI DSS requires, there should be no vulnerabilities above medium level (CVSS Base score > 4). At the same time, no one cares how fair this assessment of criticality is or how real these vulnerabilities are. All the analytics build on such formal data loses its sharpness and practical value.

PRYTEK meetup: Breach and Attack Simulation or Automated Pentest?

PRYTEK meetup: Breach and Attack Simulation or Automated Pentest? Last Tuesday, November 27, I spoke at “Business Asks for Cyber Attacks” meetup organized by PRYTEK investment platform. The event was held at the PRYTEK Moscow office in a beautiful XIX century building of a former textile manufactory.

PRYTEK Breach and Attack Simulation meetup

The goal of the meetup was to talk about new approaches in Vulnerability Analysis and how they can reduce the Information Security costs for organizations.

There were two presentations:

  • The first one was by Doron Sivan, Cronus CEO. He talked about his company’s product.
  • The second was mine. I criticized traditional vendors of vulnerability scanners, talked about things that work in companies, and things that don’t work, and what you should pay attention to when choosing a Vulnerability Management tool.

For the most part this was my report from the last ISACA VM Meetup. The only difference was in the conclusions, since the topic of this event and the audience were different.

I stressed that the Attack Simulation tools, like Cronus, that analyze vulnerabilities and network connectivity of hosts can be very helpful. They allow you to assess the criticality of each vulnerability better and help to justify the need in prompt patching for IT Team (see “Psychological Aspects of Vulnerability Remediation“).

VB-Trend 2018 Splunk Conference

VB-Trend 2018 Splunk Conference. Today I attended VB-Trend 2018 Splunk conference organized by system integrator VolgaBlob.

VB-Trend 2018

Video fragments from the event:

Comparing to “Splunk Discovery Day“, the conference was much smaller (less than 100 people), focused on technical aspects, Information Security and informal communication. And I need to say that there really was a lot of talks with colleagues from different companies, not only about Splunk, but also about Vulnerability Management, Application Security and Container Security.

Making CVE-1999-0016 (landc) vulnerability detection script for Windows NT

Making CVE-1999-0016 (landc) vulnerability detection script for Windows NT. The fair question is why in 2018 someone might want to deal with Windows NT and vulnerabilities in it. Now Windows NT is a great analogue of DVWA (Damn Vulnerable Web Application), but for operating systems. There are a lot of well-described vulnerabilities with ready-made exploits. A great tool for practising.

Well, despite the fact that this operating system is not supported since 2004, it can be used in some weird legacy systems. 😉

Adding custom NASL plugins to Tenable Nessus

Adding custom NASL plugins to Tenable Nessus. Making custom NASL scripts (plugins) for Nessus is a pretty complicated process. Basically, NASL (Nessus Attack Scripting Language) is an internal instrument of Tenable and it seem that they are not really interested in sharing it with the community. The only publicly available official documentation, NASL Reference Guide and NASL2 reference manual, was written at least 13 years ago. Certainly many things changed since then in the actual product.

Adding custom NASL plugins to Tenable Nessus

However, it’s still possible to add custom NASL scripts into the plugin set of your Nessus server. Let’s see how to do it. Everything was tested in the latest Nessus 8.

What’s new in Nessus 8

What’s new in Nessus 8. Today Tenable released a new version of their famous vulnerability scanner – Nessus 8. The existing scanner nodes don’t see the updates yet, but the installation binaries are already available. So you may try to install it.

What's new in Tenable Nessus 8

This major release will be way more positive than the previous one. Of course Tenable did NOT return the multi-user mode and API in Nessus Professional. But on the other hand, they did NOT cut the functionality even further. They even added new features in GUI. And, what is the most important, they did NOT switch to the assets-based licensing (at least yet). 🙂

ISACA Moscow Vulnerability Management Meetup 2018

ISACA Moscow Vulnerability Management Meetup 2018. Last Thursday, September 20th, I spoke at ISACA Moscow “Vulnerability Management” Meetup held at Polytechnic University. The only event in Moscow devoted solely to Vulnerability Management. So I just had to take part in it. 🙂

ISACA VM 2018 Alexander Leonov

The target audience of the event – people who implement the vulnerability management process in organizations and the employees of Vulnerability Management vendors. I noticed groups of people from Altex-Soft (Altx-Soft), Positive Technologies and Vulners.

It was very interesting to see such concentration of Vulnerability and Compliance Management specialists in one place. Questions from the audience were relevant and often concerned the weaknesses of competitors. 😉 Here I will make a brief overview of the reports. You can also read here about previous year event at “ISACA Moscow Vulnerability Management Meetup 2017“.

Talking about the audience, there were fewer people than last year, but still a lot:

The event was recorded. I will add video here as soon as it’s ready.

upd. Video in Russian. My presentation starts at 1:35:56

The event was conducted entirely in Russian, including all the slides. So, maybe I will make English subtitles and voiceover, at least for my part.
