rotocol (SNMP) is set of communications
specifications for managing network devices, such as bridges, routers, and hubs over
a TCP/IP network.
In the SNMP management architecture, one or more computers on the network act as
a network management station (NMS) and poll the managed devices to gather
information about their performance and status. Each managed device has a software
module, known as an agent, which communicates with the NMS.
Security
Managed devices can protect their MIBs by granting only specific network
management stations access. One way of doing this is through authentication.
Managed devices can require that all NMS’s belong to a community, the name of
which acts as a password that the managed devices use to authenticate management
stations attempting to gain access. Additionally, the settings for a community can
include access privileges, such as READ-ONLY and READ-WRITE, that are granted
to network management stations.
