Top 12 aspects of cloud security to consider when deploying an application to the AWS cloud

This article is intended for application developers or architects who want to understand the important security aspects of deploying their application to the cloud. It also highlights some of the available AWS services that can help in this regard. It is a high-level perspective on the main security concepts that the developer must consider and by no means fully exhaustive. However, it is intended to be a good starting point.

1) As per the Amazon Web Services (AWS) ‘Shared responsibility’ model. The customer is responsible for ‘Security in the cloud’, depending on the services the customer is using. On the other hand, AWS is responsible for ‘Security of the cloud’. This includes protecting the infrastructure that runs all the services offered in the AWS Cloud. This infrastructure is composed of the hardware, software, networking, and facilities that run AWS Cloud services.

2) AWS provides a range of services and features that are designed to ensure the security of the cloud environment. Cloud security can be broadly divided into two categories: infrastructure security and application security. In this article, we will discuss the various facets of AWS cloud security.

3) Identity and Access Management (IAM) is a critical component of AWS security. IAM enables granular access control to AWS resources, making it possible to control who has access to what resources. IAM provides a range of features, including user and group management, role-based access control, and the ability to integrate with other AWS services.

4) Authentication and authorization are two crucial concepts in cloud security. Authentication is the process of verifying the identity of a user, while authorization refers to the process of granting or denying access to resources based on the user's identity. AWS provides several tools and services that enable secure authentication and authorization, including Amazon Cognito, which provides user authentication, and AWS Identity and Access Management (IAM), which enables fine-grained access control to AWS resources. Application developers also need to understand concepts and protocols like OpenID Connect and OAuth2 which are used for secure authentication and authorization. AWS supports these protocols, making it easy to integrate third-party authentication and authorization services into an application.

5) Web security is a critical aspect of application security in the cloud. AWS provides a range of tools and services for web security, including Amazon CloudFront, which provides secure content delivery, and AWS WAF (Web Application Firewall), which provides protection against common web attacks such as SQL injection and cross-site scripting.

6) Penetration Testing and Source Code Scanning are two essential aspects of application security. Penetration testing involves simulating attacks on an application to identify potential vulnerabilities, while source code scanning involves analyzing the source code of an application for security flaws. AWS provides a range of services and tools for both these aspects of application security, including Amazon Inspector and Amazon CodeGuru.

7) Encryption is a crucial aspect of data security in the cloud. AWS provides several tools and services that enable secure encryption of data, including Amazon Key Management Service (KMS), which provides a centralized key management system, and Amazon CloudHSM, which provides a dedicated hardware security module for secure key storage.

8) Network security is a critical aspect of cloud security. AWS offers several services and features that enable network security, including Amazon Virtual Private Cloud (VPC), which provides a secure and isolated virtual network, and AWS Firewall Manager, which provides centralized management of multiple AWS WAF (Web Application Firewall) rules across accounts and resources.

9) Security monitoring and intrusion detection are essential for detecting and responding to security incidents in the cloud. AWS provides a range of services and tools for security monitoring and intrusion detection, including Amazon GuardDuty, which provides threat detection and response, and AWS CloudTrail, which enables auditing and compliance.

10) AWS Security Hub is a security service that provides a comprehensive view of security alerts and compliance status across an organization's AWS accounts. Security Hub provides a central place to view and manage security alerts and compliance status, making it easier to identify and remediate security issues and maintain compliance with industry standards and regulations.

11) Business continuity is the ability of an organization to continue its operations in the event of an unexpected disruption. AWS offers a range of services and features that enable business continuity, including Amazon Elastic Compute Cloud (EC2) Auto Scaling, which automatically scales the computing capacity based on demand, and Amazon Route 53, which provides domain name system (DNS) management and failover capabilities.

12) Disaster recovery is the ability to recover systems and data after a disaster. AWS offers several services and features that enable disaster recovery, including AWS Backup, which provides a centralized backup solution for AWS services, and AWS Disaster Recovery, which provides disaster recovery solutions for on-premises and cloud environments.

In conclusion, AWS provides a range of tools and services that enable secure cloud environments, including infrastructure security and application security. Firms also have the option to engage with AWS Managed Security Services Partners to hand hold through this process. With a range of features mentioned in this article, AWS provides a comprehensive security solution that enables organizations to use cloud computing confidently and securely.
