Introduction - Internet Of Things
- Devices (Smart Devices) interconnected with each other through the Internet
- Characteristics of IOT
- Unique Identity
- Identifies a device among all other devices using its unique identifier
- Dynamic Nature
- State changes dynamically by sensing environment
- Self Adapting
- Adapts to changing environment conditions
- Self Configuring
- Like basic setup, network configuration, software updates with minimum user intervention
- Heterogeneity
- Integrated to Information Network
- Devices working together to achieve a common goal
- Benefits of IOT
- Efficient Resource Utilization
- Saves Time

- Miniaturization of Things
- Low Energy Consumption
- Big Data & IOT
- Security Problems
- DOS (Denial of Service)
- Server gets down due to getting continuous garbage requests which results in denial of service for the valid user
- DDOS (Distributed Denial of Service)
- Information Manipulation
- Unauthorized Access
- Non valid user accessing the system using credentials stolen from a valid user
- Information Disclosure
- Disclosing the location of storage of data
- Key Elements of IOT Security
- Authentication
- Communication should be carried out only by valid/authorized users/devices
- Access Control
- Giving access to a user based on their Roles
- Data Security
- Data should be encrypted while sending from sender to receiver
- Any Modification, Alteration, Loss of data should be detected by receiver and notified to sender for retransmission
- Non-Repudiation
- Sender or Receiver can not deny the fact that they have sent or received the message
- Availability
- Resource should be available on demand without delay
