Transport Layer Security, a protocol that encrypts email messages for security and privacy

Secure Sockets Layer (SSL) is a security protocol that provides privacy, authentication, and integrity to Internet communications. SSL eventually evolved into Transport Layer Security (TLS).

Supervisory Control And Data Acquisition, runs on the same software as client computers and vulnerable to the same threats

Plant Level, lowest level and includes physical equipment and processes on the factory floor

Controller Level, real-time control of physical processes and includes devices such as Programmable Logic Controllers (PLCs)

Coordinating Computer Level, Human-Machine Interface (HMI) systems that provide a centralized view of the plant's operations

Program Logic Controller Level, manages and controls the overall production process. May include recipe management, production scheduling, and data logging

SCADA systems deal with critical services such as?

Energy, Facilities, Manufacturing, Logistics, Industrial

Real-Time Operating Systems, designed for apps such as Light Control or Navigation Systems (flight control), where everything happens in real-time. Ensures that high-priority tasks are executed within a predetermined time frame.

Engine Control Units (ECU), Anti-lock Braking Systems (ABS), Smart Home Systems

High Availability, 99.999% uptime, aka the five nines

Geo-Zone Redundant Storage, data redundancy via duplication across various regions and zones (a strategy known as geographically dispersed regions)

measured by the amount of time it takes an organization to recover from a critical failure

Power Distribution Unit, device that distributes power to devices. It can distribute power efficiently and remotely monitor power use and receive alerts

in the cloud, allow a Cloud Service Provider (CSP) to provide additional resources immediately on demand, and particularly useful with serverless architecture.
