ETSI recently announced a new specification, ETSI TS 103 523-1: Part 1 of the Middlebox Security Protocol (MSP) series, which defines the security properties of a Middlebox Security Protocol.
Middleboxes are vital in modern networks - from new 5G deployments, with ever-faster networks that need performance management, to resisting new cyberattacks with evolved threat defence that copes with encrypted traffic, to VPN provision. Industry needs middlebox technology to keep pace with these and other evolving and diverse use cases. However, middlebox deployments often raise complex and multi-layered questions around the security, privacy and trust of using middleboxes.
MSP Part 1 (ETSI TS 103 523-1) addresses this gap by specifying a new security framework for middlebox protocols, allowing middleboxes to perform vital functions securely whilst keeping up with the rapid pace of technical development. ETSI TS 103 523-1 defines provisions in the area of each of these principles, called MSP Template Requirements. Using the MSP Framework gives both a flexible and consistent threat model to use across different MSP profiles to MSP profile developers, MSP profile implementors and MSP specification writers. This methodology permits an array of use cases, as well as thorough security analysis, for the next generation of middlebox protocols: MSP.
ETSI TS 103 523-1 is Part 1 of the Middlebox Security Protocol (MSP) series; this series is a set of protocol specifications that enable secure and functional operation of next generation middleboxes.
