The OSI layers, also known as the Open System Interconnection layers, play a vital role in computer system communication across networks. Published by the International Organization for Standardization (ISO) in 1980, the OSI Model is a conceptual framework that efficiently manages computing functions and facilitates global data transmission through its 7 distinct layers.
The Physical Layer is vulnerable to network implants and rogue devices that remain undetected without proper protection. Malevolent entities have the potential to cause significant damage within an enterprise network. Jeopardizing sensitive data and disrupting critical operations. Moreover, spoofed peripherals can masquerade as legitimate Human Interface Devices (Hacked Device), further increasing the risk.
Sepio’s innovative technology addresses this gap, providing unparalleled visibility and control over the Physical Layer. By mitigating risks and identifying potential threats, our patented solution ensures robust hardware security.
What You See is Not What You Get
Traffic based visibility solutions (NAC – Moving Beyond NACs, IDS, IoT, security scanners) have blind spots. Unmanaged switches, passive taps, and out-of-band devices all fly under the traffic radar. Spoofed devices can mimic approved devices fooling traffic-based solutions. If you can’t see everything you can’t protect everything.
Your Lack of Visibility is an Attackers Gain
Cybercrime syndicates and state sponsored activities are fully aware of Fact and focus their efforts in exploiting these blind spots (either through passive implants or spoofing legitimate devices). If it sounds like a cat, feels like a cat and meows like a cat, it could still be a Raspberry Pi spoofing a legitimate cat.
Smart Devices Make Smart Attack Tools
IoT devices with their use of MAB (MAC Authentication Bypass) are your ״”soft underbelly”, implementing 802.1x and then setting up exceptions for non-802.1x compliant devices (i.e., IP cameras, printers etc.) punches a huge hole in your security defenses, expect attackers to find these holes soon enough.
Less is Not Always More
Adding physical layer visibility to your existing security stack provides full visibility of all network/peripheral devices. Sepio’s solution can easily integrate with you NAC, EPS, SIEM, SOAR putting them to better use as well as fit into your current security operational workflow.
What We See Others Don’t
Sepio’s Asset Risk Management (ARM) provides required visibility down to the physical layer going deeper and lower where other traffic-based visibility solutions can’t. Sepio’s doesn’t rely on what the device traffic is saying, we VALIDATE using Physical Layer 1 information. Trust and Verify!
