The Wind River white paper surveys security implementations for embedded systems through the CIA triad—confidentiality, integrity, and availability. Confidentiality is ensured with encryption, partitioning, and secure key management; integrity uses hashing, HMACs, secure/trusted boot, and remote attestation. Availability depends on allowlisting, intrusion detection/prevention, firewalls, and patch management. Defense-in-depth is critical, layering these controls across device design and operations. The paper also stresses covert channel analysis, random key generation, AAA frameworks, and SIEM integration for large fleets. Countermeasures include anti-tamper protections and attestation. Recommended cryptography includes AES, RSA (≥2048), SHA-2/3, and HMAC. This holistic framework balances
