Tripwire Data Collector Increases Operational Technology Visibility With Enhanced Web Scripting Capability
Tripwire Data Collector has been offering business organizations with visibility into their operational generation (OT) environments since its liberate in mid-2018.
Data will also be collected and monitored by the use of a couple of avenues – now not simplest local business protocols, akin to EtherNet/IP CIP and Modbus TCP, but additionally integrations with control programs like Rockwell’s FactoryTalk AssetCentre, MDT AutoSave and Kepware KEPServerEX, in addition to conventional IT protocols like SNMP or even HTTP.
One issue noticed within the box used to be issues accumulating operational knowledge secure in the back of a number of internet authentication strategies.
Tripwire Data Collector can track many several types of business units, akin to PLCs and RTUs, utilized in other sectors from power and utilities to production. Many of those units include precious knowledge that can simplest be to be had by the use of a internet web page.
Some of those internet pages is also extra secure than others with get entry to to be had over SSL encryption or in the back of a customized authentication or safety scheme. Not all units use the typical HTTP “basic authentication.” Some would possibly require complicated authentication after which navigation throughout a couple of pages in an effort to achieve the prized asset knowledge.
We must applaud device-makers for including security measures to operational generation units, that have lengthy lagged in the back of different sides of data generation, however the big variety of implementations necessitates ingenious auditing strategies. Automated tracking of your machine standing and configuration would possibly really feel like an insurmountable downside relying at the amount and variety of units to your atmosphere.
Fortunately, Tripwire Data Collector supplies a mechanism for tracking such units.
One fresh real-world state of affairs had us tracking knowledge from a tool made by means of Schweitzer Engineering Laboratories. Interacting with this machine in an automatic model calls for offering a username and password aggregate within the URL of an HTTP GET request after which scraping a consultation ID off the ensuing webpage. That consultation ID will have to then be supplied as a URL parameter in all next requests.
Tripwire Data Collector will also be configured to log in to this kind of machine the use of a LUA scripting capacity.
Logging in and accumulating a consultation identity may well be finished within the following way, the place the configured username and password is distributed in a GET request and the consultation ID is parsed from the ensuing web page:
frame, stat, hdrs = request('/login.html?person='..auth.username..'&password='..auth.password) fit = string.fit(frame, "session_id=x22([A-Fa-f0-9]+)x22") if desk.getn(fit) > zero then context["session_id"] = fit finish
Once established, any request can use the consultation identity inside a request like the next:
frame, stat, hdrs = request('/web page.html&session_id=’..context["session_id"])
This way of computerized internet knowledge accumulating is terribly robust. Any knowledge acquired from a tool is also checked for configuration compliance or monitored for trade all inside Tripwire Enterprise.
The Tripwire Industrial Control System (ICS) Security Suite is a perfect resolution for lots of business organizations with complicated OT units. It allows visibility into machine vulnerabilities and configurations that can have up to now been unavailable to safety groups.
The Tripwire Data Collector natively helps Ethernet/IP CIP, Modbus TCP, SNMP and Web Retriever business protocols, and integrates with Rockwell FactoryTalk AssetCentre, MDT AutoSave and Kepware KEPServerEX. This aggregate lets in for each mild and no-touch approaches to decreasing business cyber possibility.
