Hardware security refers to the protection of physical devices and their components from a range of threats, including unauthorized access, tampering, theft, and cyberattacks. It involves implementing hardware cyber security measures to ensure the integrity, confidentiality, and availability of both the device and the data it processes.
Hardware security is addressed at the physical layer by Sepio’s Asset Risk Management (ARM), which provides complete visibility into all connected assets on enterprise networks. ARM enables hardware-based risk management and strengthens the security of hardware assets by detecting and mitigating threats posed by malicious devices, whether connected via USB or network interfaces. With easily adjustable policies or default settings, you can block USB ports and disable any risky asset in real-time as soon as it is connected. ARM can be implemented progressively, starting with inventory visibility, followed by risk visibility, and culminating in the enforcement of specific security policies.
Why Hardware Security Matters?
Hardware security, network security, and endpoint security are all essential components of a comprehensive cybersecurity strategy, but they focus on different aspects of protection.
While network security focuses on safeguarding data and communication channels across the network, and endpoint security aims to protect individual devices (such as computers and smartphones) from cyber threats, hardware cyber security specifically targets the physical components that make up the network infrastructure, such as servers, routers, and IoT devices.
Hardware security is often overlooked compared to network and endpoint security. However, it’s crucial for protecting physical components from cyber attacks. Hardware attack devices, generally called rogue devices, go under the radar of human eyes and existing cyber security software tools. This false sense of security, leaves network enterprises vulnerable to hardware-based attacks and potential data breaches. Incorporating robust hardware cyber security solutions into enterprise networks is essential for preventing rogue device cyber attacks at the physical layer.
In this blog, we will explore various cybersecurity hardware risks that enterprise networks face, including supply chain attacks, hardware implants, and unauthorized peripheral devices. We will also explain how Sepio’s platform enhances network security by detecting and mitigating these risks through comprehensive monitoring and analysis of all hardware assets at the physical layer.
Validating the Security of a Hardware Device
Unlike traditional cyber security tools that focus on scanning peripheral connections, Sepio goes further by looking at the intrinsic Hardware Bill of Material (HBOM) components. This involves identifying the physical profile of each hardware device during its connection at the physical layer. This capability allow Sepio to discover and profile all connected peripheral devices. It also allows for the identification and detection of potentially malicious USB devices, even those embedded within legitimate USB devices. Securing your network also requires vigilant oversight of computer security, ensuring they are protected from tampering and unauthorized access.
Hardware security is at the core of Sepio’s Asset DNA technology, which operates at the physical layer and focuses on device existence rather than behavior. This approach effectively detects all managed, unmanaged, and hidden devices. By leveraging innovative methods and machine learning algorithms, Sepio identifies the true source of asset risk, eliminating misconceptions caused by false profiles and behavioral assumptions.
Sepio’s platform ranks assets according to their risk levels and implements precise hardware cyber security access controls. It automatically blocks devices breaking settled rules or recognized as known attack tools.
Hardware-Connected Devices Detection
Hardware security requires an inventory of all hardware-connected devices on a network. Sepio’s platform provides unique visibility into all connected hardware devices, enabling the discovery and identification of managed, unmanaged, or concealed devices. This asset risk management visibility is essential for evaluating and addressing network security vulnerabilities.
Sepio’s platform stands out in the field of network cyber security by leading a comprehensive audit for an organization’s entire hardware ecosystem. An hardware risk indicator is used to assess the actions or activities that could harm your organization assets. Sepio platform provides enterprises with an risk score from 1 to 9. Where 9 represents a high security risk, and 1 represents a low security risk posture. Each hardware risk indicator also receives a score, offering a granular breakdown of the assessment.

Hardware Cyber Security Risk Awareness
Phishing schemes often manipulate employees into actions that compromise security, such as plugging in malicious USB drives or clicking links that deploy malware. Investing in security training helps employees identify and defend against these threats, protecting hardware assets from compromise.
While enterprises strengthen defenses against traditional cyberattacks, hardware security remains overlooked, leaving it vulnerable to covert hardware attacks. As a result, rogue devices, like USB HID-emulating devices or physical layer network implants, allow hackers to bypass detection by existing security solutions, including Network Access Control (NAC), Intrusion Detection Systems (IDS), and IoT network security.
Sepio brings clarity to network-connected hardware devices, enhancing hardware cybersecurity risk awareness. The absence of effective cybersecurity solutions often leads to unnoticed vulnerabilities, creating a false sense of security. Sepio’s platform underscores the importance of hardware cybersecurity across the network enterprises, ensuring connect assets risks are properly addressed.

Prioritize and Mitigate Hardware Asset Risks
Having comprehensive visibility into all network assets is a crucial prerequisite for effective hardware defense. However, the value of this knowledge lies in its practical application. Sepio’s ARM enables you to promptly discern which network devices require attention. Leveraging Asset DNA technology and policy rules, it provides alerts for high, medium, and low risks, expediting time to resolution, identifying regulatory gaps, and foiling hardware attack tools.
The real-time actionable visibility offered by Sepio enables your security experts to gain a deeper understanding of your device attack surface and proactively manage hardware defense. Preventing social-engineering attacks and denial-of-service attempts is a key aspect of securing enterprise infrastructure.
