4. Acknowledgments
This document is a product of the IETF's Internetworking Over NBMA
Networks (ion) Working Group. The original work of the MARS MIB
developement was sponsored by Science Applications International
Corporation (SAIC).
The author would like to recognize Grenville Armitage (Bellcore), Ken
Carlberg (SAIC), Ramesh Uppuluri (Fore Systems), and Radha Gowda
SYNNET), and Bill Willcox (Fujitsu Nexion) for their support and
comments in completing the MARS MIB. Also thanks to Bert Wijnen (IBM)
for his thorough review of the MARS MIB.

6. Security Considerations There are a number of management objects defined in this MIB that have a MAX-ACCESS clause of read-write and/or read-create. Such object may be considered sensitive or vulnerable in some network environments. The support for SET operations in a non-secure environment without proper protection can have a negative effect on network operations. SNMPv1 by itself is such an insecure environment. Even if the network itself is secure (for example by using IPSec), even then, there is no control as to who on the secure network is allowed to access and SET (change/create/delete) the objects in this MIB. It is recommended that the implementers consider the security features as provided by the SNMPv3 framework. Specifically, the use of the User-based Security Model RFC 2274 [8] and the View-based Access Control Model RFC 2275 [9] is recommended. It is then a customer/user responsibility to ensure that the SNMP entity giving access to this MIB, is properly configured to give access to those objects only to those principals (users) that have a legitimate rights to indeed SET (change/create/delete) them. Note: read-access in fact may also need access-control. 7.
