Snmpv3 User Based Security Model
Q
What is the function of Masquerade in SNMPv3 security threats?
AA. Some unauthorized user may modify the contents of the message while it is in transit
BB. The message stream could be monitored by an unauthorized person by eavesdropping
CC. An unauthorized user sends information to another assuming the identity of an authorized user
DD. An authorized user is denied service by a management entity
Correct Answer:
C. C. An unauthorized user sends information to another assuming the identity of an authorized user
Explanation:
Masquerade is when an unauthorized user sends information to another assuming the identity of an authorized user. This can be done by changing the originating address. Using the masquerade and modification of information, an unauthorized user can perform an operation on a management entity, which he or she is not permitted to do. The SNMP set operation should be protected against this attack.
