• Security Names—Identify an individual user (v1 or v2c only).

• Secure Groups—Identify a security-name, security model by a group, and referred to by a group-name.

• Secure Views—Create a custom view using the VACM that controls who can access which MIB objects under agent management by including or excluding specific OIDs. For example, some users have access to critical read-write control data, while some users have access only to read-only data.

• Security Models—A security model identifies the SNMP version associated with a user for the group in which the user resides.

• Secure Access Policies—Defines who gets access to which type of information. An access policy is composed of <group-name, security-model, security-level, read-view-name>.
