VLAN attacks can be a serious issue for network security. However, there are three techniques that can be used to mitigate these attacks. First, using VLAN hopping prevention techniques can prevent an attacker from gaining access to other VLANs. Second, implementing access control policies can restrict unauthorized VLAN access. Finally, using encryption techniques can help to protect VLAN traffic from interception and manipulation. By using these techniques, you can boost the security of your network and prevent VLAN attacks.
