In a video shot for Sepio Cyber, on whose advisory board he serves, Cybersecurity Expert Joseph Steinberg warns the public about a critical vulnerability facing modern organizations: unmanaged hardware.
Steinberg explains that while companies traditionally invest heavily in software and network security, even the physical devices known to organizations often operate outside of standard IT oversight, and, as such, can easily become a massive cybersecurity blind spot. Unmanaged hardware can, for example, introduce significant risks of a vulnerability that allows attackers to bypass traditional defense mechanisms entirely.
Steinberg points out that because software runs on top of hardware, vulnerabilities in hardware can undermine any and all security implemented at the software level. Standard network-based monitoring tools, for example, are typically not equipped to handle physical layer threats and may be blind to significant dangers lurking in lower levels of the network stack. Furthermore, because many rogue or unmanaged devices operate intermittingly and/or generate minimal network traffic of their own, they sometimes evade standard software-level detection tools. Worse yet, malicious hardware is often designed to spoof legitimate device identities, rendering traditional security systems impotent as those systems often simply accept the untrusted devices as trusted equipment.
The resulting lack of visibility can create severe consequences for enterprise security and operational resilience. Steinberg notes that when organizations cannot accurately identify every physical asset connected to their network, they leave their infrastructure vulnerable to hardware-level intrusion methods, data theft, and compliance breaches. This is especially dangerous in highly regulated environments like healthcare or finance, where the integration of IT, operational technology, and IoT devices means a single unverified physical asset can compromise an entire system’s integrity. Furthermore, as Steinberg notes, hardware risks emanate from components within devices – and many organizations have little or no idea what components they are actually using; when a large number of supposably “identical” laptops are purchased from the same manufacturer, for example, those computers may actually contain a variety of different networking cards and radios – and may, as a result, be vulnerable to a variety of different threats.
To combat the problems of unmanaged (and, actually, unidentified) hardware, Steinberg advocates for a fundamental shift in how organizations approach device trust, emphasizing the absolute necessity of establishing physical layer visibility.
