CyberCentral Summit 2018 in Prague

Almost whole last week I spent in Prague at CyberCentral conference. It was a pretty unique experience for me. I was for the first time at the International conference as a speaker. And not only I presented my report there, but lead the round table on Vulnerability Management and participated in a panel session.

CyberCentral2018 my presentation

From my point of view, everything was pretty good. I successfully closed my gestalt on public speaking in English. I definitely can do it. πŸ™‚

The event was hold in Lucerna passage right in a center of Prague. Beautiful building in Art Nouveau style with famous ironicΒ  “Statue of King Wenceslas Riding an Upside-Down Dead Horse”. πŸ™‚

Even to speak in this building was a great honor. In my opinion the place was chosen ideally. It is beautiful and really good located. Lots of good hotels, restaurants and all main tourist attractions were in nearby. It was easy to go for a walk in a spare time. Some photos you can see at my Facebook page [1,2] .

Vulnerability Management for Network Perimeter

Network Perimeter is like a door to your organization. It is accessible to everyone and vulnerability exploitation does not require any human interactions, unlike, for example, phishing attacks. Potential attacker can automate most of his actions searching for an easy target. It’s important not to be such of target. πŸ˜‰

Vulnerability Management for Network Perimeter

What does it mean to control the network perimeter? Well, practically this process consist of two main parts:

  • Assessing network hosts that are facing Internet using some Network Scanner (Nessus, OpenVAS, Qualys, MaxPatrol. F-Secure Radar, etc.)
  • Assessing application servers, e.g. Web Servers, on these hosts using some special tools, e.g. Web Application Scanners (Acunetix, Burp Suite, Qualys WAS, Tenable.io WAS, High-Tech Bridge ImmuniWeb, etc.)

Active scanning is a good method of perimeter assessment. Dynamics of the assets is relatively low, comparing with the Office Network. Perimeter hosts usually stays active all the time, including the time when you are going to scan scanning them. πŸ˜‰

Most of the dangerous vulnerabilities can be detected without authorization: problems with encryption (OpenSSL Heartbleed, Poodle, etc.). RCE and DoS of web servers and frameworks (Apache Struts and Equifax case)

The best results can be achieved with scanners deployed outside of your network. Thus, you will see your Network Perimeter the same way a potential attacker sees it. But certainly, you will be in a better position:

  • You can ask your IT administrators to add your network and WAS scanners in white list, so they will not be banned.
  • You can check and correlate scan results of remote scanner with (authenticated?) scan results produced by the scanner deployed in your organization’s network and thus filtering false positives.

What about the targets for scanning? How should you get them?
