A research by OMICRON has revealed widespread cybersecurity gaps within the operational expertise (OT) networks of substations, energy vegetation, and management facilities worldwide. Drawing on information from greater than 100 installations, the evaluation highlights recurring technical, organizational, and useful points that go away vital power infrastructure susceptible to cyber threats.
The findings are primarily based on a number of years of deploying OMICRON’s intrusion detection system (IDS) StationGuard in safety, automation, and management (PAC) techniques. The expertise, which displays community site visitors passively, has supplied deep visibility into real-world OT environments. The outcomes underscore the rising assault floor in power techniques and the challenges operators face in securing growing old infrastructure and sophisticated community architectures.
Connection of an IDS in PAC techniques (circles point out mirror ports)
StationGuard deployments, usually carried out throughout safety assessments, revealed vulnerabilities similar to unpatched units, insecure exterior connections, weak community segmentation, and incomplete asset inventories. In lots of instances, these safety weaknesses have been recognized throughout the first half-hour of connecting to the community. Past safety dangers, the assessments additionally uncovered operational points like VLAN misconfigurations, time synchronization errors, and community redundancy issues.
Along with technical shortcomings, the findings level to organizational components that contribute to those dangers — together with unclear duties for OT safety, restricted assets, and departmental silos. These findings replicate a rising development throughout the power sector: IT and OT environments are converging quickly, but safety measures usually fail to maintain tempo. How are utilities adapting to those complicated dangers, and what gaps stay that might go away vital techniques uncovered?
Why OT Networks Want Intrusion Detection
The power to detect safety incidents is an integral a part of most safety frameworks and tips, together with the NIST Cybersecurity Framework, IEC 62443, and the ISO 27000 commonplace sequence. In substations, energy plant management techniques, and management facilities, many units function with out commonplace working techniques, making it not possible to put in endpoint detection software program. In such environments, detection capabilities should be applied on the community stage.
OMICRON’s StationGuard deployments usually use community mirror ports or Ethernet TAPs to passively monitor communication. Moreover detecting intrusions and cyber threats, the IDS expertise supplies key advantages, together with:
Visualization of community communication
Identification of pointless companies and dangerous community connections
Computerized asset stock creation
Detection of machine vulnerabilities primarily based on this stock
Assessing Dangers: Methodology Behind the Findings
The report relies on years of IDS installations. The primary set up dates again to 2018. Since then, a number of hundred installations and safety assessments have been performed at substations, energy vegetation, and management facilities in dozens of nations. The findings are grouped into three classes:
Technical safety dangers
Organizational safety points
Operational and useful issues
Usually, vital safety and operational points have been detected inside minutes of connecting the IDS to the community.
Usually, sensors have been linked to reflect ports on OT networks, usually at gateways and different vital community entry factors, to seize key communication flows. In lots of substations, bay-level monitoring was not required, as multicast propagation made the site visitors seen elsewhere within the community.
Hidden Gadgets and Asset Blind Spots
Correct asset inventories are important for securing complicated power techniques. Creating and sustaining such directories manually is time-consuming and error-prone. To deal with this, OMICRON used each passive and lively strategies for automated asset discovery.
Passive asset identification depends on current system configuration description (SCD) recordsdata, standardized underneath IEC 61850-6, which include detailed machine info. Nevertheless, passive monitoring alone proved inadequate in lots of instances, as important information similar to firmware variations should not transmitted in regular PAC communication.
Energetic querying of machine info, alternatively, leverages the MMS protocol to retrieve nameplate information similar to machine names, producers, mannequin numbers, firmware variations, and generally even {hardware} identifiers. This mixture of passive and lively strategies supplied a complete asset stock throughout installations.

Which Technical Cybersecurity Dangers Are Most Widespread?
OMICRON’s evaluation recognized a number of recurring technical points throughout power OT networks:
Weak PAC units:
Many PAC units have been discovered to be working with outdated firmware containing recognized vulnerabilities. A notable instance is the CVE-2015-5374 vulnerability, which permits a denial-of-service assault on protecting relays with a single UDP packet. Though patches have been out there since 2015, quite a few units stay unpatched. Comparable vulnerabilities in GOOSE implementations and MMS protocol stacks pose extra dangers.
Dangerous exterior connections:
In a number of installations, undocumented exterior TCP/IP connections have been discovered, in some instances exceeding 50 persistent connections to exterior IP addresses in a single substation.
Pointless insecure companies:
Widespread findings included unused Home windows file sharing companies (NetBIOS), IPv6 companies, license administration companies working with elevated privileges, and unsecured PLC debugging capabilities.
Weak community segmentation:
Many services operated as a single giant flat community, permitting unrestricted communication between tons of of units. In some instances, even workplace IT networks have been reachable from distant substations. Such architectures considerably enhance the influence radius of cyber incidents.
Surprising units:
Untracked IP cameras, printers, and even automation units incessantly appeared on networks with out being documented in asset inventories, creating severe blind spots for defenders.
The Human Issue: Organizational Weaknesses in OT Safety
Past technical flaws, OMICRON additionally noticed recurring organizational challenges that exacerbate cyber threat. These embrace:
Departmental boundaries between IT and OT groups
Lack of devoted OT safety personnel
Useful resource constraints are limiting the implementation of safety controls
In lots of organizations, IT departments stay chargeable for OT safety — a mannequin that always struggles to deal with the distinctive necessities of power infrastructure.
When Operations Fail: Practical Dangers in Substations
The IDS deployments additionally revealed a spread of operational issues unrelated to direct cyber threats however nonetheless affecting system reliability. The most typical have been:
VLAN points have been by far essentially the most frequent, usually involving inconsistent VLAN tagging of GOOSE messages throughout the community.
RTU and SCD mismatches led to damaged communication between units, stopping SCADA updates in a number of instances.
Time synchronization errors ranged from easy misconfigurations to units working with incorrect time zones or default timestamps.
Community redundancy points involving RSTP loops and misconfigured change chips induced extreme efficiency degradation in some installations.
These operational weaknesses not solely influence availability however may amplify the implications of cyber incidents.
