Security considerations in Edge Computing
Security requirements
Infrastructure tamper detection and classification
Aggregate information of Edge sites
% of compute nodes trusted
% of compute nodes not trust verified.
Tamper detection of verifier in each site
TPM based attestation security
Verification of new software installation/upgrade (Usage of Linux IMA).
Secure communication between ONAP and Site (TLS or IPSEC)
Certificate based authentication between ONAP and Site
Certificate Enrollment
Mutual CA
Security of private keys using hardware root of trust (e.g TPM or SGX)
Secret Management
Centralized Secret management with decentralized distribution
Security in decentralized case (e.g SGX based security)
