Securing Layers 2 and 3 to Stop Lurking Cyber Threats

Lurking beneath the surface of your network, hidden within Layers 2 and 3, could be a multitude of threats. Firewalls, while important, can’t always stop a determined attacker who gains a foothold. Network Access Control (NAC) acts as a powerful line of defense against these silent invaders.

Imagine your network as a bustling marketplace. Traditionally, anyone could enter and roam freely. Genians NAC brings order to this chaos, meticulously verifying every device and user before granting access. This “Zero Trust” philosophy assumes everyone and everything is a potential threat until proven otherwise

Why Layers 2 & 3 Are Critical

The Open Systems Interconnection (OSI) model provides a framework for understanding network communication. Layers 2 (Data Link) and 3 (Network) are the foundation for secure data flow. Here’s where traditional security measures often fall short:

  • Layer 2 (Data Link): This layer governs how devices communicate on the physical network. Traditional methods rely on MAC addresses for identification, but these are easily spoofed by attackers using techniques like MAC address cloning. A rogue device with a cloned address can gain unauthorized access, eavesdrop on traffic, or launch further attacks.
  • Layer 3 (Network): This layer deals with logical addressing and routing of data packets across the network. Here, threats like ARP spoofing and rogue DHCP servers wreak havoc. In ARP spoofing, an attacker tricks your system into directing traffic to a malicious device masquerading as a legitimate one. Rogue DHCP servers can issue fake IP addresses, granting unauthorized devices access to your network resources.

Genians NAC: Your Layer 2 & 3 Guardian and A Cornerstone of Zero Trust

Implementing Genians NAC empowers your organization with a robust defense against evolving cyber threats:

  • Device Profiling & Threat Detection: Genians NAC goes beyond simple MAC address verification. It analyzes every single connected device on the network, identifying suspicious behavior and rogue devices attempting to mimic legitimate ones.
  • Layer 2 & 3 Threat Detection: Genians NAC focuses on securing the foundational layers of network communication (Data Link and Network). It actively detects and mitigates threats like ARP spoofing, rogue DHCP servers, and MAC address cloning, which traditional methods often miss.
  • Continuous Monitoring & Compliance Enforcement: Genians NAC acts as a vigilant guardian, continuously monitoring network activity for suspicious behavior.  
  • Policy Enforcement & Access Control: Genians NAC enforces pre-defined security policies. If a device doesn’t meet compliance standards (e.g., outdated software, missing patches), Genians NAC restricts access until they meet security standards.
  • No Disruptions, No Downtime: Genians NAC leverages innovative network sensing technology. This eliminates the need for complex integrations with existing network switches or wireless controllers, ensuring a smooth deployment process with no disruptions or downtime to your critical business operations.

Fortify Your Network with Confidence
