This MIB is intended for those devices where
SNMP access is given to be given to known SNMP 
Manager only. All the SNMP MIBs are published, 
any thrid party SNMP browser can retrieve data 
using SNMP protocol. By implementing this MIB, a
application layer handshake has to be done before 
any MIB view access is granted to SNMPV2c community 
string or SNMPV3 user. 

Once the handshake is successfully over then SNMP 
agent can create VACM entry to provide access to any
MIB view. 

                   GLOSSARY
 
View-based Access Control Model ( VACM )

The VACM determines whether access to a managed 
object in a local MIB by a remote SNMP manager 
should be allowed.
