Layer 1 Visibility – Cybersecurity First

Layer 1 Visibility

Cybersecurity Awareness Month – Week 4, Cybersecurity First

Here at Sepio we like to stress the importance of Layer 1 visibility. But why is Layer 1 such a crucial element to your cybersecurity efforts? Below are some facts about Layer 1 that will better explain its crucial role in protecting your organization.

Looks Can Be Deceiving

Traffic-based visibility solutions, such as NAC, IDS and IoT Network Security, lack Layer 1 visibility. Such blind spot allows unmanaged switches, passive taps, and out-of-band devices to fly under the radar while spoofing devices get recognized as legitimate devices. Layer 1 visibility provides a panacea to such security challenges by identifying all devices for what they truly are through their Physical Layer information. Asset management efforts are ineffective if you don’t know what assets you actually have.

When you can see everything, you can protect everything.

See All Evil

Cybercrime syndicates and state-sponsored actors are fully aware of the Layer 1 visibility challenge and focus their efforts on exploiting this blind spot. There is a range of attack tools available on the market that operate on Layer 1. In doing so, these tools, collectively known as Rogue Devices, evade detection, allowing bad actors to covertly carry out their attacks, whether that be data theft, malware injection, or DDoS, to name a few. Without Layer 1 security, organizations can’t accurately determine what (or who) is operating within their infrastructure, which is a major security risk.

If it sounds like a cat, feels like a cat, and meows like a cat, it still might be a Raspberry Pi spoofing a legitimate cat.

Smart Devices, Smart Loopholes

Internet of Things devices, such as IP cameras and printers, present vulnerabilities due to their use of MAC Authentication Bypass (MAB). These non-802.1x compliant devices can effortlessly gain unauthorized network access by spoofing a legitimate MAC address. By setting up exceptions for non-802.1x compliant devices, you create a huge hole in your security defenses – a hole large enough for attackers to enter through.

Don’t let smart devices outsmart your security efforts.

Less is Not More

Your existing cybersecurity investments are not a waste of money. Organizations still need their current solutions. However, they, alone, cannot protect the organization from the myriad of threats faced. In fact, nothing out there, on its own, can enable complete protection. Yet, Layer 1 information provides the foundation for a more effective cybersecurity approach. Hence, when integrated with Layer 1 visibility, existing solutions such as NAC, EPS, SIEM and SOAR, are put to better use, and the organization achieves a stronger security posture.

The first layer is your sixth sense – but you still need the others.

Eyes like a hawk

Layer 1 visibility is not something out of a fairy tale. Sepio’s Hardware Access Control (HAC-1) solution works on the hardware level to provide the required visibility, down to Layer 1 data. Sepio’s solution goes deeper and lower than any other solution has gone before to ensure that your devices are trusted and are not just claiming to be by validating Layer 1 information. Lastly, with HAC-1’s complete visibility, organizations can effectively enforce their access control measures through Zero Trust Hardware Access.

We see what others don’t.

Now that you know why Layer 1 visibility is so vital, let us help you achieve it. In just 24 hours you can see what assets you really have and achieve a stronger cybersecurity posture. Going deeper doesn’t have to be a struggle…

Layer 1 Visibility

Sepio platform uses a novel algorithm, a combination of physical layer fingerprinting module coupled with a Machine Learning module – providing the sought-after visibility and enforcement level, it is further augmented by a threat intelligence database – ensuring a lower risk hardware infrastructure.

Hardware Assets Control solution for iot security

Sepio Hardware Access Control HAC-1, provides 100% hardware device visibility.

HAC-1 enables Hardware Access Control by setting rules based on the devices characteristics.

HAC-1 instantly detects any devices which breach the set rules and automatically block them to prevent malicious attacks.

The idea is to Verify and then Trust that those assets are what they say they are.

With greater visibility, the zero-trust architecture can grant access decisions with complete information.

Thus, enhancing the enterprise’s protection within, and outside of, its traditional perimeters.

The Hardware Access Control capabilities of HAC-1, block Rogue Devices as soon as they are detected

Our HAC-1 solution stops an attack at the first instance, not even allowing such devices to make network access requests.

Sepio Hardware Access Control HAC-1 provides 100% hardware device visibility. No device goes unmanaged. Rogue Devices are block as soon as they are detected. HAC-1 solution stops an attack at the first instance, not even allowing such devices to make network access requests.

Physical Layer Fingerprinting

Sepio is the only company in the world to undertake Physical Layer fingerprinting . HAC-1 detects and handles all peripherals; no device goes unmanaged.

With this total visibility, a stronger cyber security posture is achieved. There is no longer needed to rely on manual reporting or employee compliance. Sepio manage security and provides answers to questions such as:

  • Do we have an implant or spoofed device in our network?
  • How many IoT devices do we have?
  • Who are the top 5 vendors for devices found in our network?
  • Where are the most vulnerable switches in our network?

Having visibility across all hardware assets provides a more comprehensive cyber security defense. Reduce the risk of a hardware attack being successful and our private health data being stolen.

Founded in 2016 by cybersecurity industry veterans from the Israeli Intelligence community, Sepio’s HAC-1 is the first hardware access control platform that provides visibility, control, and mitigation to zero trust, insider threat, BYOD, IT, OT and IoT security programs.

Sepio’s hardware fingerprinting technology discovers all managed, unmanaged and hidden devices that are otherwise invisible to all other security tools. Sepio is a strategic partner of Munich Re, the world’s largest re-insurance company, and Merlin Cyber, a leading cybersecurity federal solution provider.

Heavy spending on cybersecurity should bring a high return on investment, yet gaps in visibility limit this. Sepio Hardware Access Control (HAC-1) solution provides a panacea to gaps in device visibility to ensure you are getting the most out of your cybersecurity investments. HAC-1 integrates with existing solutions, such as NAC, EPS, SIEM and SOAR, to enhance the organization’s cybersecurity posture. HAC-1’s deep visibility capabilities mean no device goes unmanaged; the solution identifies, detects, and handles all IT/OT/IoT devices.

Moreover, HAC-1’s policy enforcement mechanism and Rogue Device Mitigation capabilities instantly block any unapproved or rogue hardware. In doing so, ultimately, HAC-1 enables a Zero Trust Hardware Access approach which stops attackers at the first line of defense.

Sepio supporting compliance

Sepio Hardware Access Control (HAC-1) solution provides entities with the Physical Layer coverage they need to obtain complete device visibility. And, in doing so, also provides protection against hardware-based attacks. As the leader in Rogue Device Mitigation (RDM), Sepio’s solution identifies, detects and handles all peripherals; no device goes unmanaged.

HAC-1 uses Physical Layer fingerprinting technology and Machine Learning to calculate a digital fingerprint from the electrical characteristics of all devices and compares them against known fingerprints.

In doing so, HAC-1 is able to provide organizations with ultimate device visibility and detect vulnerable devices and switches within the infrastructure. In addition to the deep visibility layer, a comprehensive policy enforcement mechanism recommends on best practice policy and allows the administrator to define a strict, or more granular, set of rules for the system to enforce. When a device breaches the pre-set policy, HAC-1 automatically instigates a mitigation process that instantly blocks unapproved or Rogue hardware.

Furthermore, HAC-1’s RDM capabilities support compliance with Section 8 of the EO, which concerns the government’s investigative and remediation capabilities. Section 8 focuses on enhancing data collection efforts in order to improve the investigation and remediation processes following an incident. HAC-1 logs all hardware asset information and usage and maintains such data for a period defined by the system administrator.
