Study Notes
Threats to IoT Systems
- Two main types of threats: threats against IoT and threats from IoT.
- Threats against IoT include hacking IP cameras via buffer overflow, DDoS attacks on Dyn Servers, botnet attacks on IoT devices, and SQL injection attacks.
- Threats from IoT involve cross-site scripting attacks targeting private data and privacy risks posed by Unmanned Aerial Vehicles (UAVs).
IoT Security Requirements
- Security needs classified into three types: information-level, access-level, and functional-level.
Information-level Security Requirements
- Confidentiality: Only authorized individuals can access data, ensuring privacy and protection of proprietary information.
- Integrity: Prevents unauthorized tampering of sensor data and device modifications.
- Non-repudiation: Guarantees the sender's certainty against denial of sent data.
- Freshness: Validates the recency of sent or received messages.
Access-level Security Requirements
- Authorization: Ensures only permitted users gain access.
- Identification and Authenticity: Validates user identity.
- Access Control: Regulates who can access which resources.
- Availability: Ensures systems are operational and accessible when needed.
- Exception Handling: Manages unexpected issues effectively.
- Self-organization: Allows IoT systems to configure themselves without manual input.
Classification of IoT Security Threats
- Device Category: Low power and high power attacks. Low-power attacks can disrupt normal device behaviors; high-power devices can launch extensive attacks due to their internet capabilities.
- Access Level: Active and passive attacks. Passive attacks monitor transmissions while active attacks disrupt communication, impacting both confidentiality and integrity.
- Attacker Location: Internal vs. external attacks.
- Attack Strategy: Physical attacks cause damage to device configurations while logical attacks disrupt functionality without physical contact.
- Information Damage Levels: Eavesdropping, alteration, message replay, and interruption.
Specific Attack Types
- Eavesdropping: Passive listening to ongoing communications.
- Alteration: Unauthorized modification of information.
- Fabrication: Introducing false information to mislead communication.
- Message Replay: Replaying messages affects data freshness.
- Interruption: Disrupts availability of services.
- Host-based Attacks: Includes hardware, software, and user compromises.
- Protocol-based Attacks: Encompasses jamming, tampering, flooding, unfair channel access, and packet collision.
