In today's world, where cloud technologies play a **crucial role** in data storage and processing, security concerns are especially significant.

Data is a **valuable asset for any organization** or individual user, making its protection from hackers and fraudsters a top priority.

Let's examine **how security is ensured** in cloud technologies, using **Amazon Web Services** as an example, one of the leaders in this field.

## Common Principles of Data Security in the Cloud

The **key principles** of cloud security are **confidentiality**, **integrity**, and **availability of data**.



We're not planning to develop cloud technologies ourselves, so it's not essential for us to know **exactly how these security measures are implemented**. What matters most right now is ensuring that **our data is secure**. Let's explore how the cloud services we're considering, such as **AWS**, provide this protection.

## Methods of Information Protection in AWS

## Summary

If you're **just starting** with cloud technologies and are **concerned about the security** of your data, it's important to know that **major cloud providers** like AWS allocate significant resources to **ensuring security** and **complying with regulatory** requirements. The best approach is to start by **learning the basic principles** and security practices offered by your provider, and **actively using the tools** and services they provide to protect your data.

With **modern technologies** and a solid security strategy, cloud services can be both convenient and a highly reliable way to store and process data.

Which principle of security ensures that data cannot be altered or destroyed without authorization?

Which AWS service provides fine-grained control over access policies for users and applications?

Discover the world of cloud computing by exploring its core technologies and practical applications in this course! We’ll begin with the fundamentals of cloud computing and then focus on essential AWS services like S3 (Simple Storage Service) for scalable storage, EC2 (Elastic Compute Cloud) for virtual servers, and RDS (Relational Database Service) for managed databases. Gain hands-on experience as you learn how these services integrate to support modern applications efficiently.

Learn about the history and development of cloud technologies, as well as how modern servers and web applications operate. Dive into the different cloud models, understand the offerings of major cloud service providers, and explore the security fundamentals that ensure safe cloud operations. 

We'll explore a cloud service called S3, and learn how to configure and use it. You'll upload various media to S3, and then we'll even learn how to host a simple static website on S3.

We’ll dive into understanding what EC2 is and how it works. You’ll learn what EC2 is used for, how to create and manage instances, and how to connect to them from your device. Additionally, we’ll guide you through the basics of working with EC2 instances and demonstrate how to deploy your own website on an EC2 web server.

We will learn how to create and use databases in the cloud. I'll tell you about the different types available, how they interact with applications, and integrate with various products. Cloud databases are the most secure way to store data, and this section will explain why.
