WITH REVISED AND UPDATED
ANSWERS
Internet of Things (IoT) - Answer-the network of physical objects that are embedded
with software or sensors that allow them to gather and distribute data over the internet

-depends on the interoperability, extensibility, scalability and modularity of it.
Sensing Layer - Answer-is integrated with available hardware objects to sense the
statuses of things
Network Layer - Answer-is the infrastructure to support over wireless or wired
connections among things
Service Application Layer - Answer-is to create and manage services required by users
or applications
Interfaces Layer - Answer-consists of the interaction methods with users or applications
Applications of IoT - Answer--Comsumer Applications
ex. smart home, healthcare
-Industrial Applications
ex. industry 4.0
-Infrastructure Applications
ex. smart city
IoT Security Issues - Answer--interdependence between devices (in general)
-diversity/heterogeneity of devices (in general)
-limited computing resources per individual device
-unattended devices
-myriad of data (device specific)
-intimate relationship with uses (device specific)

tunnel" within the public network
-requires authentication
-enhances message integrity and confidentiality
Instrusion Detection System (IDS) - Answer-work like burglar alarms and combine tried
and true detection methods from intrusion detection systems with the capability to react
to changes in the environment which is available in intrusion prevention technologies
-can both detect and prevent
Intrusion Detection and Prevention Systems can prevent attacks via: - Answer--
terminating the network connection or attacker's user session
-changing the security environment by reconfiguring network devices to block access to
the targeted system
