Loopguard - The loop guard feature checks if a root port or an alternate root port receives BPDUs. If the port is receiving BPDUs, the loop guard feature puts the port into an inconsistent state until it starts receiving BPDUs again.
Rootguard - It is enabled on the designated ports of root switch, so that if those ports listen to the superior BPDU then put that port in inconsistent state.
BPDU Guard - BPDUGuard enables on access port which helps the switches to put the port in shut down mode once it receives the superior BPDU.
BPDU filtering - allows you to avoid transmitting BPDUs on PortFast-enabled ports that are connected to an end system.By default, spanning tree sends BPDUs from all ports regardless of whether PortFast is enabled. BDPU filtering is on a per-switch basis; after you enable BPDU filtering, it applies to all PortFast-enabled ports on the switch.
