Simple Network Management Protocol v3 Training (SNMPv3)
SNMPv3 Training Course – Hands-on
SNMPv1 and SNMPv2c both provide “community string” security, also called “Trivial Authentication”. SNMPv3 offers significant improvements. The SNMPv3 architecture incorporates new descriptions for SNMP Entities (Managers, Agents, Proxy Forwarders), updated message formats, and Standard MIBs used to configure access to Entities. New features include: User authentication using entity shared secret keys, along with message time stamps; data secrecy using encryption; and control of user access to MIB information based on the need to know.
SNMPv3 messages can be sent at any of the following three levels of security:
- No Authentication and No Encryption. Also called “noAuth/noPriv”, “Priv” referring to Privacy. Only a valid User Name is required to access data or to send a trap.
- Authentication and No Encryption, also called “Auth/noPriv”. The User must be authenticated as a valid user for the message to be accepted. This is accomplished by sharing a secret key, and using that key to produce a message hashed authentication code sent with each message.
- Authentication and Encryption, also called “Auth/Priv”. The User is authenticated and the data payload is encrypted using a second shared secret key.
SNMPv3’s View Access Control Model (VACM) is used to control access to specific MIB data. Individual users are configured into groups, and groups might have the following privileges. Only Security Administrators can access the MIB data to configure SNMPv3 MIBs at remotely managed agents. Microwave Engineers can control remote microwave radios, including the ability to reboot them if necessary. The report generator group can access appropriate read-only data as needed.
This intensive, one-day SNMPv3 Training, the second of out three-course series on SNMP, outlines the new message formats, the SNMPv3 configuration MIBs and related RFC’s, and describes the relationships. It will help you understand the threats addressed by SNMPv3, and the methods used to counter those threats.
SNMPv3 Training Course – Customize it
- We can adapt this SNMPv3 Training course to your group’s background and work requirements at little to no added cost.
- If you are familiar with some aspects of this SNMPv3 Training course, we can omit or shorten their discussion.
- We can adjust the emphasis placed on the various topics or build the SNMPv3 Training around the mix of technologies of interest to you (including technologies other than those included in this outline).
- If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the SNMPv3 Training course in manner understandable to lay audiences.
