ETSI releases Middlebox Security Protocols specification for fine-grained access control
General News

Network operators, service providers, users, enterprises, and small businesses require being granted varied (fine grained) permissions. At present, the solutions used often break security mechanisms and/or ignore the desire for explicit authorization by the endpoints. This intrusive "break-and-inspect" method, ignoring the desire for explicit authorization by endpoints, raises questions around security, privacy and trust. TLMSP was born from an academic effort that evolved into ETSI TC CYBER – adding security measures against known attacks, and more features including auditing, a more flexible message format, adaptation to varying network conditions, on-path middlebox discovery and improved handling of errors. The use cases for TLMSP are many and varied, forming the basis of ETSI’s MSP hackathon: • system and user security, including cyber defence and protection of user data • operational use cases including in Content Delivery Networks • compliance by network operators with obligations and service agreements, and discharge of transparency and audit obligations in regulated industries • maintaining enterprise network and data centre visibility ETSI TS 103 523-2 is Part 2 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.
