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)
