Dangerous actors goal manufacturing, processing vegetation and utilities as open targets as a result of the operational know-how (OT) and IT integrations used don’t present the safety wanted to guard the core methods that run vegetation. By making the most of extensive safety gaps between IT, OT and industrial management methods (ICS) that weren’t designed for securing operations, dangerous actors seize the chance to launch ransomware assaults.
Generally even large-scale assaults, together with these on Colonial Pipeline and JBS Meals, which illustrate the vulnerability of vegetation, utilities and methods, are the results of IT and OT methods’ safety gaps that dangerous actors have a tendency to take advantage of.
IT/OT gaps result in safety breaches
Processing vegetation, utilities, producers and provide chains that depend on IT and OT methods have tech stacks designed for velocity, effectivity and store ground management. Sadly, ICS, IT, OT and legacy enterprise useful resource planning (ERP) methods usually are not usually designed with safety as a major aim. Consequently, the tech stacks constructed on these methods have extensive IT/OT safety gaps the place implicit belief leaves them weak to assaults.
Eighty-six % of process and discrete manufacturers report having restricted visibility into their ICS environments, making them an open goal for cyberattacks. On the system degree, a typical ICS is troublesome to retrofit and allow extra strong instruments like zero-trust community entry (ZTNA) on the software degree. Consequently, these methods turn out to be targets for dangerous actors who can scan IT and OT infrastructure and tech stacks and discover open companies, IP addresses and different endpoints which might be solely unprotected. That is such an issue that the U.S. Cybersecurity and Infrastructure Security Agency (CISA) issued an alert earlier this 12 months warning of such assaults targeting ICS and SCADA devices.

A recent survey by the SANS Institute, in collaboration with Nozomi Networks, discovered that probably the most distinguished problem organizations report with securing OT applied sciences and processes is integrating legacy and growing older OT know-how with fashionable IT methods.
“With the evolution of latest assault frameworks, legacy gadgets, evolving know-how choices and useful resource constraints, the largest problem with securing management methods applied sciences and processes is the technical integration of legacy and growing older ICS/OT know-how with fashionable IT methods,” the survey’s authors write. “Amenities are confronted with the truth that conventional IT safety applied sciences usually are not designed for management methods and trigger disruption in ICS/OT environments, they usually want path on prioritizing ICS-specific controls to guard their precedence property.”
Fifty-four % stated it’s the best problem they face in securing their operations as we speak, adopted by conventional IT safety applied sciences not being designed for management methods and inflicting disruption in OT environments. Moreover, 39% of the respondents say ransomware is probably the most important concern relating to assaults on their ICS- and OT-based infrastructure.
The SANS research additionally factors out that a number of ICS amenities fell sufferer to the Ekans ICS-tailored ransomware. Notable firms, together with Honda and multinational vitality firm Enel Group, the place the adversary group demanded $14 million in ransom for the decryption key and to forestall the attackers from releasing terabytes of stolen knowledge.
Honeywell helps shut gaps with zero belief
Getting zero belief proper throughout manufacturing and processing vegetation and utilities optimized for OT and ICS methods is a problem as a result of, in contrast to conventional IT stacks and community infrastructure which have endpoints with an OS or firmware put in, OT and ICS-based methods depend on programmable logic controllers (PLCs) to watch plant and equipment course of efficiency.
Infrastructure operators that hold water remedy, electrical utilities and course of manufacturing vegetation working depend on supervisory management and knowledge acquisition (SCADA) methods which might be designed for monitoring, not safety. Defending the provision, reliability and security of their industrial management methods and operations can turn out to be more difficult as new processes are added to an current plant.
Upwards of 85 distributors are vying to offer zero-trust capabilities to processing vegetation and utilities by providing endpoint detection and response (EDR), managed companies, and cloud-based platforms for working whole processing operations. One participant within the area, Honeywell, differentiates itself by how a lot knowledge it will possibly seize throughout various networks and interpret it in actual time to avert intrusions and breaches.
“Honeywell was the group that had cybersecurity specialists who have been in a position to attain our goal. With our OT DCS engineers, their mentality, and current collaboration with Honeywell engineers, we had a strong basis to construct on,” Ioannis Minoyiannis, head of automation at Motor Oil, stated on Honeywell’s website.
Earlier this month, on the firm’s Honeywell Join 22 occasion, it launched two advances in its cybersecurity options aimed toward serving to processing vegetation and utilities progress on ZTNA framework initiatives. Moreover, its Advanced Monitoring and Incident Response (AMIR) managed cybersecurity service added dashboard visibility.
Offering better visibility and management over menace detection, safety monitoring, alerting and incident response based mostly on safety info and occasion administration (SIEM) and safety orchestration and automation and response (SOAR) capabilities, Honeywell helps course of producers and utilities construct out ZTNA frameworks.
By figuring out and responding to threats sooner with early menace detection, menace searching, remediation and incident response, AMIR managed companies helps producers make progress on their ZTNA initiatives. Moreover, menace notifications and steerage assist harden endpoints and provides any group perception into how greatest to section networks sooner or later whereas implementing least-privileged entry.
Honeywell’s AMIR managed service is a step within the path of treating each id and endpoint as a brand new safety perimeter for a processing plant, producer or utility.
Honeywell’s service is for all ICS property, no matter producer
Preserving the design standards for ZTNA frameworks as outlined by NIST requirements, Honeywell’s AMIR managed service is vendor-neutral, supporting each Honeywell and non-Honeywell property on an ICS community. The AMIR managed service is designed to assist mitigate complicated OT safety incidents, threats and cyberattacks by means of incident response assist supplied by Honeywell’s safety professionals.
Data and updates are additionally supplied by way of automated and rapid customized alerts and routine pattern stories. As well as, the corporate designed the enterprise dashboard to offer clients with assist 24/7.
“AMIR helps fill a serious safety hole that many industrial clients presently face: the lack to watch OT environments 24/7 and proactively detect and reply to evolving threats,” stated Jeff Zindel, vp and normal supervisor of Honeywell cybersecurity. “The addition of an AMIR dashboard provides clients enhanced visibility to know the standing of recognized incidents and the steps being taken by Honeywell OT cyber professionals to assist reply to lively threats.”
Cyber App Management, beforehand often known as Utility Whitelisting, was additionally launched, with vendor-agnostic assist for each Honeywell and non-Honeywell management methods. It’s designed to offer a further safety layer that ensures solely identified and trusted purposes can run on ICS property. The Nationwide Institute of Requirements and Know-how (NIST) considers Cyber App Management important for OT safety.
Cyber App Management makes use of the most recent software program launch from safety specialist VMware Carbon Black, with particular guidelines and configurations crafted particularly for OT environments, developed by Honeywell’s OT Cybersecurity Facilities of Excellence and Innovation.
Prioritizing ZTNA for the longer term
Dangerous actors will proceed to prioritize the softest targets that ship the most important ransomware funds, starting with processing and utility vegetation which might be core to produce chains. Locking up a provide chain with ransomware is the payout multiplier that attackers need as a result of producers usually pay as much as hold their companies working.
Any enterprise that integrates OT, IT and ICS methods might wish to look at the advantages of pursuing a ZTNA-based framework to safe its infrastructure. Implementing a ZTNA framework doesn’t must be costly or require a whole workers. Gartner’s 2022 Market Guide for Zero Trust Network Access is one reference that may outline guardrails for any ZTNA framework. With each id a brand new safety perimeter, producers should prioritize ZTNA going into 2023.
