"Clear, Concise, Correct – The Only Q&A Pack You Need
Function as a Service (FaaS) - A category of cloud computing services that provides a
platform allowing customers to develop, run, and manage application functionalities without the
complexity of building and maintaining the infrastructure typically associated with developing
and launching an app.
What are cloud users responsible for - application-level security
What are cloud vendors responsible for - physical security and some software security
risks of cloud computing - Abuse, insecure interfaces, malicious insiders, shared technology,
data loss, account or service hijacking, unknown risk profile,
multi-instance model - provides a unique DBMS running on a virtual machine instance for
each cloud subscriber
multi-tenant model - provides a predefined environment for the cloud subscriber that is
shared with other tenants, typically through tagging data with a subscriber
identifier
Keystone - Security model for openStack. Provides identity and token
IoT (Internet of Things) - Continuing development of the Internet that allows everyday
objects embedded with electronic devices to send and receive data over the Internet.
, Information Technology (IT) - the computers and other electronic devices used to store,
retrieve, transmit and manipulate data. Primarily using wired connectivity
Operational Technology (OT) - A communications network designed to implement an
industrial control system rather than data networking.
Like machines embedded with IT
Actuator - single purpose devices bought by consumers
cloud enabled IoT - unlimited resources and seamless communication
edge device - it is installed closer to a client device, such as a workstation or a security door,
than to the core or backbone of a network
gateway - A node on a network that serves as a portal to other networks.
Fog Computing - Provisioning processing resource between the network edge of IoT devices
and the data center to reduce latency.
core network - connects geographically dispersed fog networks and other networks using
high performance routers.
MQTT (Message Queuing Telemetry Transport) - A (TCP/IP) publish/subscribe network
protocol that is defined by OASIS and used in Internet of Things (IoT) devices.
MQTT is a protocol used to send messages between devices. It is used in remote environments
with limited bandwith.
