The separation of critical services from noncritical services can occur on layer two broadcast domain. Separation could involve the isolation of broadcast or collision domains through Virtual Local Area Networks VLANs. This helps reduce the risk of Address Resolution Protocol ARP storms during heavy scanning events or denial of service attacks DoS. The major threat on the network is DoS attacks which use the broadcast storm flooding as TCP syn flood to engage the servers. This paper demonstrate how VLANs could be used to reduce the impact of DoS attacks on the servers. The simulation was carried out using Cisco Packet Tracer 6.0.1. Two scenarios were presented, first one showed flooding the server before VLANs and second scenario showed how VLANs could reduce flooding the servers so using VLANs reduce the impact of DoS attacks as mentioned in scenario two.
