Explain Why is VLAN trunking a security risk?
Answer:
while physical separation between network segments,VLAN
rely on switching should be perfect, if not
so,misconfiguration or a bug could cause the VLAN barriers
to be broken
There i a 2 risk
1.packet leaks from one VLAN to another, possibly revealing
sensitive information
2.In the second, a specially crafted packet is injected
into another VLAN. Any attack that could cause the VLAN
barriers to break requires a machine directly attached to
the physical network. This means that only a local machine
can execute an attack against the switch.
