Your company's network just finished going through a SAS 70 audit. This audit reported that overall, your network is secure, but there are some areas that needs improvement. The major area was SNMP security. The audit company recommended turning off SNMP, but that is not an option since you have so many remote nodes to keep track of. What step could you take to help secure SNMP on your network?
Block all internal MAC address from using SNMP
Block access to UDP port 171
Block access to TCP port 171
Change the default community string names
