Security Considerations

SNMP-based monitoring tools require that the manager be provided access to the relevant MIBs. In order to limit security risks, such access will typically be provided on a selective basis. For example, the authentication and access control facilities in SNMP v3 can be used to limit access to authorized users.

MBONE-mapping tools such as map-mbone should be used with care since in flooding mode they can result in excessive load on multicast routers.

Through use of RTP monitoring tools, it may be possible to obtain sensitive information on user viewing habits. In order to protect against this, encryption technologies such as IPSEC can be used to provide confidentiality.
