Cybersecurity Modernization for Critical Infrastructure Industries

With a zero trust, mesh overlay approach, modern cybersecurity solutions like Xage Security Fabric allow mission-critical operations to run reliably, securely, and keep pace with shifting compliance requirements.

Numerous organizations and enterprises worldwide are strengthening digital infrastructure in an effort to move from information-based operations to intelligent, data-based operations. This evolution has ushered in a new round of digital transformation covering both IT (Information Technology) and OT (Operational Technology) systems. Through real-time data and information, enterprises can make timely, valuable decisions on production, machine maintenance, supply chain, and workforce to create more innovative business models.

As businesses and operations embrace digital transformation, they spread across enterprise systems, cloud services, and ecosystem partners, which involves interactions between various users, applications, machines, and data streams. For enterprises with various locations or sites, existing infrastructure is unable to provide the security and responsiveness needed for changing business models. The evolution of existing security models is essential to optimize operations and support a connected workforce.

While IT/OT convergence strategies help organizations grow and compete, they also open the door to risk. Integration can expose mission- and business-critical systems to cyber threats through existing vulnerabilities and newer threats in connected networks. According to the U.S. Department of Homeland Security, previous legacy systems were at less risk due to the separation of IT systems and additional physical protection measures. With the convergence of IT and OT systems, cybersecurity approaches should also evolve to protect operations.

Many businesses are not sufficiently prepared to tackle cybersecurity risks when converging systems. While the Industrial Internet of Things (IIoT) has become a vital competitive factor in critical industries, associated equipment, operations, and networks remain a main target of cyberattacks. Recent high-profile intrusions in mission-critical applications, such as oil & gas pipeline systems and municipal water systems, highlight the potential risk.

Protecting Critical Industry Operations

Data is crucial for effective operations and automation, but it is even more vital in critical infrastructure industries that can affect the safety of field and floor personnel, in addition to the public. Data must be objective and trusted in order to make mission-critical decisions in both IT and OT environments. If critical data is manipulated or breached, it can lead to hazardous, costly events, with impacts that reach beyond the bottom line.

Standard security technologies for OT and IT system protection, such as firewalls, VPNs, and access management tools, are not evolving fast enough to meet changing needs in critical infrastructure applications. Today’s security solutions are also usually outdated, overly complex, inflexible, and lack the ability to scale for distributed operations. A scalable, robust cybersecurity architecture is needed that not only protects assets, but also advances the business.

Keeping up with Security Directives and Compliance Requirements

High profile, critical industry operations also must keep up with evolving government cybersecurity mandates and compliance requirements, all without affecting overall productivity. These cybersecurity mandates, along with escalating cyber attacks, are drivers of cybersecurity modernization in many industries, such as energy, utilities, and defense.

For example, the Transportation Security Administration (TSA) issued its Cybersecurity Directive in 2021 for owners and operators of oil and natural gas pipelines in the U.S. The TSA’s directive and recent revisions target continued efforts to build cybersecurity resilience in critical pipelines, and businesses must comply. To keep up, organizations need to cyber harden operations by utilizing a zero-trust-led security approach.

Another example includes hardware certifications required for rugged or hazardous locations, commonly found in energy and utility industries. Occupational Safety and Health Administration (OSHA) Publication 3073 defines a hazardous location (HazLoc) as an area where flammable liquids, gasses or vapors, or combustible dusts exist in quantities that can produce an explosion or fire.

In hazardous locations, specially-designed equipment and installation techniques are required to protect against the explosive and flammable potential of substances. With innumerable industry experience, Advantech designs and develops inter-operable devices that meet industry-specific and location certifications to mitigate safety risks. Various Advantech product lines are also industry specific, such as for power and energy or intelligent transportation, to meet a range of certifications and requirements.

Xage Zero Trust Security Approach

With a zero trust approach to protecting OT systems and OT-IT interconnections, Xage security solutions utilize identity-based access control to protect users, machines, apps, and data at the edge and cloud. Xage Fabric enforces Zero Trust Access (ZTA) to secure operations and data, which includes overall system visibility and managed access that adjusts dynamically for convenience and safety. Dynamic ZTA security means flexibility for end-users that have unique access needs.

Xage works with existing systems with no changes required to operational assets or networks. A mesh overlay approach to implementing zero trust capabilities allows for easy deployment without affecting existing equipment. Cybersecurity mesh essentially defines a security perimeter based on the identity of a person, asset, or application. It enables a modular, responsive security approach by centralizing policy orchestration and distributing policy enforcement.

Whether you are in IT, OT, security, network management, process engineering, operations or business transformation, the Xage Fabric is flexible for varying end user needs.

Interoperability with Advantech Rugged Hardware

Xage Fabric Solution Deployment

As cybersecurity evolves from static, network-based perimeters, organizations must also evolve with a zero trust protection methodology based on user, asset, and data stream identities. Critical data protection is vital for maintaining security and compliance as data travels across networks outside of traditional OT siloes. 

The integration of IT and OT is inevitable, but there are cybersecurity approaches that help prevent exposing IT or OT infrastructure to breaches. Partnerships like Xage Security and Advantech help deliver comprehensive security solutions for customers who need to implement risk-free digital transformation in complex industries.
