SNMP Research Announces Support for TLS and DTLS

Knoxville, TN, April 25, 2011 - SNMP Research International, Inc. is pleased to announce the availability of solutions supporting Simple Network Management Protocol operations over Transport Layer Security (TLS) and Datagram Transport Layer Security (DTLS). SNMP Research's (D)TLS option provides secure SNMPv3 communication that uses public-key cryptography and X.509 certificates as an alternative to the private-key cryptography required by the SNMPv3 User-Based Security Model (USM). SNMP Research's (D)TLS option makes it easier to integrate SNMP network management into X.509 public key infrastructures.

SNMP over TLS and DTLS provides comparable security to SNMPv3 with USM while leveraging existing investments in X.509 public key infrastructures. SNMP over TLS and DTLS offers the following security features (similar to the User-based Security Model).

Organizations may consider implementing SNMP over TLS and DTLS if they:

Why? Because SNMPv3 users, applications, and devices must be configured to communicate securely. The User-based Security Model secures SNMPv3 with usernames that have localized keys configured on agents and corresponding passwords configured on managers. SNMP over TLS and DTLS provides comparable security to USM, but uses X.509 certificates stored on agents and managers rather than usernames and passwords. If an organization is already required to use X.509 certificates, it makes sense to also enable SNMP-manageable network devices and managers to use X.509 certificates, as well. However, secure SNMPv3 can be achieved without requiring X.509 certificates or establishing a public-key infrastructure. The SNMPv3 User-based Security Model provides sufficient security for organizations that do not need to use TLS or DTLS. While SNMP Research supports TLS and DTLS by providing the (D)TLS option, we emphasize that the security provided by the SNMPv3 Framework is comparable whether using usernames and passwords or X.509 certificates.

SNMP Research presently supports the (D)TLS specifications published in these RFCs:
