IoT Data Analytics Challenges
Scaling problems : Continually send data, relational databases can grow incredibly large very quickly.
Volatility of data: With relational databases, it is critical that the schema be designed correctly from the beginning.
• Due to the lack of flexibility, revisions to the schema must be kept at a minimum.

Securing IoT
OT Security
Cybersecurity incidents in industrial environments can result in physical consequences that can cause threats to human lives.
Operational interruptions have occurred in OT environments due to cybersecurity incidents.
Attackers were skilled individuals with deep knowledge of technology and the systems they were attacking.
Challenges in OT Security
Erosion of Network Architecture
Pervasive Legacy Systems
Insecure Operational Protocols
Common Industrial Protocols - Modbus
- DNP3 (Distributed Network Protocol)
- ICCP (Inter-Control Center Communications Protocol)
- OPC (OLE for Process Control)
