Passive mapping and risk analysisfor industrial networks

The UMX Explorer passive probe inventories the industrial network without sending anything onto it. UMX Risk Manager turns it into an IEC 62443 risk analysis and a costed action plan.

UMX ExplorerNetworksPassive listening
UMX Explorer, Networks view: 55 assets placed on five Purdue levels, from L1 Basic control to L4/5 Enterprise, with the channels observed between subnets.
Capture of UMX Explorer on Ultrametrix's demonstration plant. The animation follows the channels the capture shows and adds no data to it.

From the mirror port
to the decision page

The process has four steps. Every image is a capture of the consoles, taken on Ultrametrix's demonstration data.

Connect

The probe plugs into a mirror port. Nothing is installed on the controllers.

A copy of the traffic

The switch copies the traffic to the probe through a mirror port (SPAN) or a TAP. The probe listens without sending anything: over a 24-hour bench test, no frame left its capture port.

Every mirror port checked

The console shows the traffic received port by port. The umx doctor command checks that the mirror session carries exchanges between other machines.

Observe

The inventory is built from the exchanges observed on the network.

Controllers identified by their protocols

Vendor, model and firmware version are read in the Modbus, S7 or EtherNet/IP answers. Every field gives its source; a value not seen is marked “not observed”.

Purdue levels and flows between networks

Each asset is placed from the structure of its exchanges, never from an address range. The flows between subnets are drawn and counted.

Remote access

For SSH, Telnet, VNC, RDP, SMB and VPNs: who connects to which device, when, and whether the channel is encrypted. It is read in the protocol, not inferred from the port number.

Analyze

UMX Risk Manager builds the IEC 62443 risk analysis from that map.

Zones and conduits, proposed then validated

Risk Manager proposes zones from the capture. Your engineer confirms, renames or splits them. The HAZOP study then sets the target security level (SL-T).

Risk before and after countermeasures

Inherent risk, analyzed risk, then current and planned residual risk. Every score shows its calculation and the share of the evidence that is inferred or potential.

Costed action plan

Every countermeasure carries a cost, an effort and the risk it removes per thousand euros. The actions are ranked by that ratio.

Decision page

The first five actions, their cost and the risk each one removes, with a decision and signature block for management.

Document

From the analysis, Risk Manager produces the reports and the projection onto the ReCyF.

Projection onto the ReCyF

The analysis is projected onto the 20 objectives of ANSSI's ReCyF v2.5, a working document. Every status points to the project's dated evidence or to the declaration to provide. The projection helps prepare the NIS2 file; it is neither a certificate nor a compliance verdict.

Seven reports

Risk analysis of the site and of each zone, decision page, ReCyF audit, action plan, registers of remote access and of risk acceptances.

55 assets, including 14 OT

The demonstration plant as the probe saw it, then imported into Risk Manager. One square stands for one asset.

Five of them were still to be confirmed by an engineer on the day of the capture.

costed actions in the plan

Each with its cost, its effort and the risk it removes.

passive findings to handle

Including four skipped Purdue levels and an OT-to-IT flow, read in the traffic, without an active scan.

IEC 62443-3-2 risk analysis

Risk analysis and action priorities

  • Zones and conduits, HAZOP, target security levels
  • Inherent, analyzed and residual risk
  • Costed action plan, decision page
  • Projection onto the ReCyF v2.5, seven reports in French and English
HAZOP summary in Risk Manager: the most severe consequence sets a target security level SL-3.

Threat intelligence module (CTI)

Off by default. Once on, it sends only the scope the operator confirms: domains, public addresses, brands, keywords and products (vendor, model, version). The inventory, the topology and the risk analysis do not leave the site.

Reports produced by Risk Manager

Seven reports, in French and in English, produced from the console for management and auditors.

Runs on site, offline by default

The probes, the central console and Risk Manager run inside your network, including an isolated one. Two functions can reach the outside, both off by default: the CTI module, limited to the scope the operator confirms, and the check for new versions.

Ultrametrix

Non-destructive testing
and industrial cybersecurity

Ultrametrix is a non-destructive testing laboratory based in Saint-Genis-Laval, near Lyon, France. It examines parts and structures without altering them, for industry and buildings. UMX applies the same principle to the industrial network: observe without interfering.

Try it first

UMX Explorer is free: plug it into a mirror port and see what it finds on your network. The results shown here come from Ultrametrix's demonstration plant; with UMX, Ultrametrix opens a new activity.
