Introduction to secure engineering of the Internet of Things: definition, basic concepts, security requirements, types of devices and architectures. Types of attacks: wireless reconnaissance and mapping, physical security attacks, security protocol attacks, application security attacks. Principles of secure engineering in IoT: building security into design and development, threat modeling, compliance, system monitoring, penetration testing, security training and education. Cryptography in IoT: algorithms for encryption, decryption, hash functions, digital signatures, cryptographic controls built into IoT messaging and communication protocols, key exchange. Identity and access management in IoT: registration and device lifecycle, authentication mechanisms, IoT IAM (Identity and Access Management) infrastructure, access control schemes, trust models. Data protection and privacy preservation in IoT: challenges and requirements for privacy preservation in IoT, privacy impact assessment, schemes for privacy protection. Cloud security for IoT: cloud services for IoT, cloud security controls for IoT, new approaches in cloud computing and IoT integration.
