Industry Specification Group (ISG) Encrypted Traffic Inspection (ETI)
ISG ETI develops Group Specifications (GS) and Group Reports (GR) that define requirements and identify the use cases of Encrypted Traffic Inspection techniques to mitigate against threats to networks and users arising from the deployment of encrypted traffic. The group defines detailed specifications of mitigation measures with a view to their further development in ETSI Technical Committees that are identified as appropriate for their adoption.
As a pre-standardization activity, the ISG ETI intends to frame the security concerns arising from widespread adoption of encryption by default in networks and to build the foundation of a longer-term response to the threats from encrypted.
The underlying rationale for ISG ETI is that a paradigm of "encrypted by default" has been adopted by many network and service providers without taking due account of any threats to network resilience and security. The network management oversight that is accepted for non-encrypted traffic may be lost when an all encrypted paradigm is adopted. The aim of ISG ETI is to better describe the issues and to establish essential requirements to allow for inspection of such traffic.
