Periodic Reporting for period 1 - iTrust6G (Intelligent Trust and Security Orchestration for 6G Distributed Cloud Environments)

Okres sprawozdawczy: 2024-01-01 do 2024-12-31

Podsumowanie kontekstu i ogólnych celów projektu

iTrust6G aims at designing and implementing a network architecture based on zero-trust principles to increase the trustworthiness of 6G networks at several levels: AI/ML algorithm exploited for threat handling, asset compliance, explainable security policies and asset observability.
This would be to improve the accuracy and the efficiency of (i) methodologies used for trust determination (e.g. threat posture assessment from collected and generated cyber-threat intelligence, cyber-risk assessment from vulnerability assessment procedure, number of the assurance conformity check), (ii) the performance and coverage of the security procedures involved (e.g. number of classes of monitored resources, mean time-to-detection of threat, mean time-to-reaction), and (iii) the induced overhead over network resources exploitation (e.g. performance overhead due to the programmability models).
iTrust6G overall objectives are:

Objective 1. Design an End-to-End system security architecture that capitalizes on zero-trust principles to enable a trustworthy 6G service management platform, addressing dynamic network and application-level security requirements.

Objective 2. Exploit AI to detect novel threats from operated assets and generate pertinent cyber threat intelligence enacting their proactive protection.

Objective 3. Conceive novel Trust Algorithms (TA) exploiting AI integrated into trust management system (TM) accounting for forensics evidence.

Objective 4. Design and implement intelligent solutions for AI-driven security orchestration, across extreme edge, edge and public clouds (across the continuum) exploiting programmability models for pervasive enforcement.

Objective 5. Specify, develop, and integrate intent-based security policies/engine, for explainable and automated E2E security orchestration.

Objective 6. Develop solutions for dynamic, configurable and intelligent placement of network functions over network slices and applications, to secure service design and delivery.

Objective 7. Perform trial-based validation of solutions in trusted execution environments (TEE) and on specialized hardware (accelerators, etc.), based on defined use-cases requirements.

Objective 8. Ensure dissemination of project results, contributions to standardisation, exploitation of results and innovation management.

Prace wykonane od początku projektu do końca okresu sprawozdawczego oraz najważniejsze dotychczasowe rezultaty

A first iteration of the system architecture exploiting zero-trust principles (Technical Objective 1) allowing trustworthy 6G management, dynamic network and the specification of application-level security requirements have been prepared and documented in the iTrust6G D2.2. The project proposes a three-tier architecture featuring multi-domain collaboration (collaborative threat intelligence), trust management in a single administrative domain (policy administration, static and dynamic trust assessment, security orchestration), and infrastructure resource supervision (infrastructure layer) in the cloud continuum. This document also presents how the components of this architecture for continuous trust assessment, risk and threat evaluation and cyber-threat intelligence have been documented. In complements, iTrust6G D2.1 have documented a set of three different use cases to elicit validation objectives, relevant stakeholders and functional requirements over the architecture's components.
Initial approaches for exploiting artificial intelligence from operated assets and threat intelligence generation (Technical Objective 2) have been investigated. Initial 5G/6G datasets have been selected to define initial monitoring requirements and train machine learning models for threat detection. This allowed an initial work for threat intelligence generations through, i) the construction of STIX 2.1 reports, ii) their storage into a Cyber Threat Intelligence (CTI) platform, and, iii) the application of the gathered CTI for trust score computations on operated assets from their threat exposure.
The conception of a novel trust management system and trust algorithms (technical objective 3) has started during this reporting period. A first version of the remote attestation framework has been developed and integrated in Kubernetes. A preliminary version of identity management version has been tooled via the integration of Keycloack2F with Lightweight Directory Access Protocol (LDAP) and implementing an access control policy framework with Open Policy Agent (OPA) and Apache APISIX3F for fine-grained access control.
The preparation of an intelligent solution for AI-driven security orchestration (Technical Objective 4) have delivered several design and implementation results. The programmability security models and architecture for the resource generator have been placed and define several interfaces for generating service images. The main components of the security orchestrator have been established and positioned for deployment. End-to-end workflows to enable data ingestion, enrichment and correlation from diverse sources.
The consortium also initiated several works to build an intent-based security policy and engine (technical objective 5). Specifically, a trust model has been defined in iTrust6G D2.3 and the specification of intents to enact policy. The design foundation of a notary service to maintain trust records and serve accountability.
Finally, the consortium laid the foundation for a solution for the placement of network functions network slices and applications (technical objective 6). An initial version of a secure service orchestrator is under design by iterating over Opensource Mano solution. A policy verification module has been implemented to input a trustable placement service. The module supports slice management.
