Understanding Switch Security Issues
Describing Unauthorized Access by Rogue Devices
Switch Attack Categories
- MAC layer attacks
- VLAN attacks
- Spoof attacks
- Switch device attacks
MAC address Flooding | Port Security |
VLAN Hooping | Tighten up trunk configurations and the nogotiation state |
Attacks between devices on a common VLAN | Implement Private VLANS(PVLANs) |
DHCP Spoofing | USe DHCP Snooping |
Spanning tree compromises | Proactively configure the primary and backup root devices, Enable root guard |
MAC Spoofing | Use DHCP Snooping. Port security. |
ARP Spoofing | Use Dynamic ARP Inspection. DHCP Snooping, Port Security |
CDP Manipulation | Diable CDP on al ports where it is not intentionally used. |
SSH & Telnet attacks | Use SSHv2. Use Telnet with VTY ACLs |
