What is Docker Compose? Docker Compose is a tool for defining and running multi-container Docker applications. It allows you to create a YAML file that defines the services, networks, and volumes for your application, and then uses that file to create and manage the containers. Docker Compose is a great way to simplify the process of building, shipping, and running multi-container applications.

Environment Variables Environment variables in Docker are key-value pairs that can be passed to a Docker container at runtime. They are used to configure the behavior of the application running inside the container without changing the container image itself.
Environment variables can be set in a Dockerfile using the ENV instruction or passed to the container when it is run using the -e flag with the docker run command. These variables can be accessed by the application running inside the container to customize its behavior based on the environment it is running in.
What are Docker Images? Docker images are read-only templates that contain everything needed to run a container, including the application code, runtime, libraries, dependencies, and configuration files. They are built using a declarative file called a Dockerfile, which specifies the instructions for creating the image. Docker images are stored in a registry, such as Docker Hub, from where they can be pulled and run on any Docker-enabled host.
The key characteristics of Docker images are:
Script VS Program The terms “script” and “program” are often used interchangeably, but there are some distinctions between them:
Script: A script is a type of program that is usually written in a scripting language. Scripts are typically used to automate tasks or perform specific functions within a larger software system. Scripts are often interpreted rather than compiled, meaning they are executed line by line by an interpreter. Examples of scripting languages include JavaScript, Python, Perl, and Bash.
Business Continuity Planning (BCP): Business Continuity Planning (BCP) is the process of creating a strategy to ensure that essential business functions can continue during and after a disaster or disruption. BCP involves identifying potential risks, developing plans to mitigate those risks, and implementing measures to maintain critical operations. BCP does not concentrate on restoring full business activities and services. It focuses on critical products and services that the organization provides and ensures those important areas can continue to operate even on reduced level of performance until business returns to normal.

Introduction In today’s digital age, information security threats are a constant concern for organizations of all sizes. The National Institute of Standards and Technology (NIST) offers a powerful tool to combat these threats: the Risk Management Framework (RMF). This framework provides a structured, yet adaptable, approach to managing security and privacy risks.
This article explores the NIST RMF’s seven key steps, empowering you to implement a robust risk management strategy.
