The threat behind MAC spoofing<\/strong><\/h2>

When implementing any insurance policy, you need to start with estimating the level of risk, the probability of that risk, and the potential damage should that risk become a reality.<\/p>

One of the network risks that is often presented to demonstrate the ineffectiveness of 802.1x solutions is the ease of bypassing modern network access control (NAC) by using MAC spoofing<\/a>. Usually, this involves spoofing the network printer or other vulnerable device.<\/p>

Now, let\u2019s put aside the fact that network printers today can support certificate or credential-based authentication, and that certain products have remedies against such attempts even when the authentication is based on MAC.<\/p>

Let\u2019s consider: is MAC spoofing a legitimate threat or an exaggerated, manageable flaw?<\/p>

But before I try to analyze this risk, I want to point out the biggest advantage a NAC solution can give an organization to cope with modern cyber security threats: the ability to apply dynamic segmentation based on device type or identity.<\/p>

Without going into too much detail, NAC is one of the only systems that can help you prevent lateral movement, indirectly allowing you to identify breaches and directly helping you to prevent the compromise of your crown jewels.<\/p>
