9. Security Considerations 9. Security Considerations
Security issues are not discussed in this memo. This MIB adds no security issues that are not raised by SNMP itself.
As a Network Management Protocol, SNMP is capable of changing the
configuration of a system, of denial of service attacks through
requiring the agent to respond to its messages, and displaying values
of system counters and configuration settings in the clear where an
adversary might read them. This, however, is not in itself a threat:
this is the function of the protocol, but could be misused. Such
misuse can be avoided or minimized through SNMP Security.
