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
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.
