As cyber threats evolve, hardware security measures have become an essential component of a comprehensive cybersecurity strategy. While traditional security solutions focus on software vulnerabilities, attackers increasingly target the physical layer—leveraging hardware-based attacks to bypass detection and infiltrate critical systems.
At the Global Cyber Innovation Summit Virtual Event, Bentsi Benatar, Co-founder & CMO at Sepio Systems, explored the challenges in harnessing OSINT (Open-Source Intelligence) for hardware security and highlighted why organizations must adopt a multi-layered approach to protect their physical infrastructure.
The Growing Threat of Hardware-Based Attacks
Unlike software vulnerabilities, hardware threats are often overlooked due to a lack of visibility at the physical layer. Attackers exploit this blind spot by using:
- Rogue Devices – Malicious hardware disguised as legitimate peripherals (e.g., USB cables, keyboards, or network devices).
- Supply Chain Compromise – Hardware implants introduced during manufacturing or distribution.
- Insider Threats – Employees or contractors introducing unauthorized devices into secure environments.
- Physical Tampering – Direct modifications to hardware components to gain unauthorized access.
These threats cannot be mitigated by traditional security tools, such as NAC, EDR, or IDS, which operate at higher network layers and lack Layer 1 visibility.
Essential Hardware Security Measures
To defend against hardware-based threats, organizations must implement proactive security measures that provide complete asset visibility, threat detection, and policy enforcement.
Asset Visibility & Inventory Management
- Know what’s connected – Maintain a real-time inventory of all IT, OT, and IoT assets.
- Identify unauthorized devices – Detect shadow IT and rogue hardware before they become a security risk.
- Leverage AI-driven classification – Distinguish between legitimate and malicious devices instantly.
Hardware-Based Zero Trust Enforcement
- Deny access to unknown devices – Implement a Zero Trust Hardware Access Policy where only authorized devices can connect.
- Continuous monitoring – Enforce strict authentication controls at the hardware level.
- Risk-based policy enforcement – Take automated actions based on real-time risk scoring.
Supply Chain Security & Hardware Integrity Checks
- Vendor risk assessments – Conduct thorough security audits of hardware suppliers.
- Pre-deployment validation – Inspect new hardware before integration into critical systems.
- Firmware integrity monitoring – Detect unauthorized modifications to device firmware.
Physical Security & Insider Threat Prevention
- Restrict physical access – Implement strict access controls for sensitive hardware assets.
- Surveillance & logging – Monitor and log physical interactions with critical hardware.
- Insider threat awareness – Train employees on the risks of social engineering attacks and hardware manipulation.
The Role of OSINT in Hardware Security
Open-Source Intelligence (OSINT) is a powerful tool for identifying potential hardware threats, but it comes with challenges:
- Lack of hardware-specific OSINT data – Most OSINT efforts focus on software vulnerabilities rather than hardware risks.
- Complex supply chain mapping – Tracking the origin of hardware components across multiple vendors is difficult.
- Limited real-time threat intelligence – OSINT sources often lag behind real-world attack developments.
To maximize OSINT effectiveness, organizations must correlate external intelligence with internal hardware security monitoring to detect emerging threats before they materialize.
How Sepio’s Asset Risk Management (ARM) Platform Helps
Sepio’s ARM platform provides organizations with:
- 100% Hardware Asset Visibility – Identify every connected device, even those undetectable by traditional security tools.
- Automated Risk Scoring – Assess the security posture of each device in real time.
- Hardware-Based Zero Trust Implementation – Enforce security policies at the physical layer.
- Threat Detection & Mitigation – Identify rogue devices and prevent unauthorized access.
By integrating hardware security measures with advanced asset risk management, organizations can achieve true Zero Trust enforcement and eliminate blind spots that cybercriminals exploit.
Stay Ahead of Hardware-Based Cyber Threats
As attackers increasingly shift toward hardware-level exploits, organizations must prioritize hardware security measures to defend against Rogue Devices, insider threats, and supply chain risks.
