Which term refers to a method that adds additional layers to VLAN tags to bypass security?

The term that refers to a method which adds additional layers to VLAN tags to bypass security is known as Double Tagging. This technique involves the manipulation of VLAN (Virtual Local Area Network) tags within Ethernet frames.

In a typical situation, a switch checks the VLAN ID of incoming frames to ensure they belong to the correct VLAN. Double Tagging exploits the fact that VLAN tags are added to frames by tagging a frame with two VLAN IDs instead of one. The outer tag is processed by the first switch, which removes it and forwards the frame based on the inner tag to a different VLAN. This can allow an attacker to send a frame into a VLAN without authorization, ultimately potentially gaining access to sensitive information or resources in that VLAN.

This method is a specific case of a VLAN hopping attack, allowing an attacker to traverse VLAN boundaries by sending frames to a different VLAN indirectly, thus undermining the security model of VLANs intended to isolate network segments from one another. Understanding this concept is crucial for implementing VLAN security measures and configuring switches correctly.

The other options refer to different malicious techniques or security measures. ARP Spoofing relates to the manipulation of ARP packets to redirect network traffic, Switch Spoofing involves tricking a switch into thinking a
