Industrial cybersecurity solutions provider Radiflow recently announced the launch of an automated risk analysis platform for industrial automation and control systems.
Named CIARA (Cyber Industrial Automated Risk Analysis), the solution is now generally available after some of Radiflow’s customers tested the beta version. CIARA is a cloud-based service that can be used as a standalone tool or in combination with other Radiflow solutions. Customers can operate it on their own or they can have a consultant operate it for them.
CIARA adheres to the ISA/IEC 62443 cybersecurity standards, and it can be useful not only for assessing an organization’s security posture, but also for ensuring that regulatory requirements are met.
CIARA collects information from an organization’s network and external sources and uses it to calculate the likelihood of being impacted by a threat. The risk is calculated based on this likelihood and potential impact, with the impact depending on the criticality of business processes.
When a customer first configures CIARA, they are asked to enter their country and sector, and select the security controls and products they are currently using. They are also instructed to provide a security report in the form of a digital production image, which can be generated using other Radiflow products or using PCAP files.
These settings and data will help customers get a more accurate risk assessment for their specific OT environment. The CIARA dashboard provides users a threat level score based on how targeted their sector and country is (e.g. threat actors known to target that sector/country and the methods they use), shows the likelihood of each business process being impacted, and it provides information on the efficiency of deployed mitigations.
“CIARA automates the process of examining hundreds of the most commonly used security controls, against simulation of hundreds of cyber threat types while modelling against dozens of features for the digital network models including protocols, vulnerability, firmware versions, topology, device type and many others,” explained Yehonatan Kfir, CTO at Radiflow.
“These risk assessments are then factored against common OT risk scenarios including loss of availability, loss of control, damage to property and other. The result is a matrix of potentially tens of thousands of permutations that can’t be analysed by humans while CIARA is able to evaluate it and provide comprehensive reports in a few minutes,” he added.
CIARA also provides organizations information on the steps they need to take to address the identified problems, it helps them plan the timeline for deploying mitigations, and shows information on the budget they need to achieve those goals.
Radiflow pointed out that the platform can be used by enterprises looking to audit their branches, as well as by government agencies. For instance, a recent round of attacks on Israel’s water sector leveraged vulnerable cellular equipment. The government had told organizations to ensure that their cellular communications equipment was not vulnerable, but some of them failed to take action, enabling threat actors to breach their systems. Radiflow says a tool such as CIARA would have allowed the government to more easily assess the security posture of those water companies.
In terms of pricing, CIARA is offered based on an annual subscription per customer site, with the standard cost at $15,000 per site per year.
