What are Three Techniques for Mitigating VLAN Attacks?

What are three techniques for mitigating VLAN attacks choose three?

Here are the three techniques for mitigating VLAN attacks:

1. Use a firewall
2. Use an intrusion detection system
3. Configure your switch

A firewall can be used to block traffic between VLANs, preventing attackers from being able to communicate with devices on other VLANs.

An intrusion detection system can be used to monitor traffic and identify suspicious activity, such as attempts to communicate with devices on other VLANs.

Configuring your switch to not allow untagged frames to be forwarded between VLANs will prevent attackers from being able to communicate with devices on other VLANs.

6 other techniques for mitigating VLAN attacks

1. Implement private VLANs
2. Use port security
3. Configure Spanning Tree Protocol (STP)
4. Enable VLAN Access Control Lists (ACLs)
5. Use a Virtual Private Network (VPN)
6. Implement Quality of Service (QoS)

Private VLANs can be used to isolate traffic within a VLAN, preventing attackers from being able to sniff traffic or inject malicious traffic onto the VLAN.

Port security can restrict access to specific ports on a VLAN. This will prevent unauthorized devices from being able to access the VLAN.

Spanning Tree Protocol can be used to prevent loops in the network. This will prevent attackers from being able to create a loop and flood the network with traffic.

VLAN Access Control Lists can be used to control traffic on a VLAN. This will allow you to specify which devices are allowed to communicate on the VLAN.

A Virtual Private Network can be used to encrypt traffic between VLANs. This will prevent attackers from being able to eavesdrop on traffic or inject malicious traffic onto the VLAN.

Quality of Service can be used to prioritize traffic on a VLAN. This will ensure that critical traffic is able to get through even if the network is congested.

What are three possible VLAN attacks?

Here are three possible VLAN attacks:

1. Attacking the physical infrastructure
2. Spoofing MAC addresses
3. Flooding the network with traffic

Attacking the physical infrastructure attack involves physically damaging or destroying equipment, such as switches or routers.

A spoofing MAC addresses attack involves impersonating another device on the network by spoofing its MAC address.

Flooding the network with traffic attacks involves flooding the network with so much traffic that it becomes overloaded and can no longer function properly.

What protocol should be disabled to help mitigate VLAN hopping attacks?

The protocol that should be disabled to help mitigate VLAN hopping attacks is the Dynamic Trunking Protocol (DTP). DTP can be used by attackers to automatically negotiate a trunk link between two devices, allowing them to bypass security measures and access devices on other VLANs.
