Lecture 6 Flashcards
What is the Internet of Things (IoT)?
A network of physical objects embedded with sensors, software, and other technologies to connect and exchange data with other devices and systems over the Internet.
Why is IoT security particularly challenging?
Due to resource constraints, dynamic communication, long lifespan, headless nature, and heterogeneous protocols.
What is meant by ‘headless nature’ of IoT devices?
Many IoT devices lack a user interface, making security configuration and updates difficult.
What is tamper resistance in IoT?
The ability of a device to resist physical manipulation and unauthorized access.
Why is heterogeneity an issue in IoT security?
Because different devices and manufacturers use varying standards and protocols.
What is Zero Trust in the context of IoT?
A model where no device or user is automatically trusted – verification is required at all times.
What is the role of VPN in IoT?
To create secure communication tunnels for IoT devices.
What are some network-level IoT protections?
Firewalls, VPNs, IDS/IPS.
What does ‘security by design’ mean?
Building security into devices and systems from the beginning of development.
What kind of threats have evolved in IoT?
From hackers to organized crime and nation-state actors.
What are cybersecurity trust labels?
Labels indicating the security level or compliance status of IoT devices.
