AWS Cloud Security: Risks, Services, Best Practices, And Tools

Article Summary

Amazon Web Services or AWS has gained worldwide popularity for being one of the most quickly established cloud services out there. Its services include storage and computing of data, networking, and delivery of content. This article will discuss the risks associated with it, the most important security services offered by it, and the best practices and tools for enhanced AWS cloud security.

Every new invention in the cyberworld comes with its own vulnerabilities and threats that need to be taken care of. The same rule of thumb applies to AWS or Amazon Web Services since it plays host to a myriad of applications and their data. 

AWS Cloud Security is a feature offered by AWS to protect your applications along with the data stored and transmitted by it. AWS makes use of the shared responsibility model for security. This means that security for the cloud infrastructure is managed by AWS while the customers are responsible for their own applications and data. 

AWS security controls are measures doled out by the cloud service provider to keep their infrastructure and their client data safe and secure from harm’s way. Deploying AWS security best practices and tools help organizations and the service provider stay compliant with a host of security standards, as well as keep their security measures up to date. 

This article will detail the risks faced by AWS, important AWS security services, and the best practices and tools for well-rounded security. 

Top AWS Cloud Security Risks

Every cloud service security out there, including the AWS cloud security, is occasionally plagued by certain forms of risks. Such areas of vulnerability can affect its performance and holistic security. Some of the top AWS cloud security risks have been explained further to help better understand the threat they pose. 

1. Poor Identity and Access Management

Identity and access management refer to the efficient management of individuals who can access certain data and those who can’t. This is done by granting authorization and then access to specific individuals. 

However, in some cases, poor IAM can lead to the wrong individuals being granted access to sensitive information. This is where proper authorization and authentication play a crucial role since they can help prevent unauthorized access. 

This is especially concerning when access is still available to previous and inactive employees. Lack of role-based access is yet another reason for such a risk to arise. 

2. Understanding Liability

AWS has a shared responsibility model. This means that the security of the AWS platform is covered by AWS but the responsibility for securing the applications and data falls on the customer organizations themselves. 

Understanding this concept is crucial in having a clear-cut understanding of who the liability falls under in case there’s a mishap in security procedures that lead to a data breach. Users have to deal with access control, login monitoring and more as this falls under the domain of their application and data’s safety. 

3. Improper Data Encryption

AWS provides its customers with an easy and cost-effective way to store their data through S3 buckets which are formally known as Simple Storage Service. Customers can create these buckets from any point in the world and store their data in them. 

However, the issue lies in the fact that these private buckets of information can easily be made public by anyone who has an AWS account. This can lead to huge amounts of data being lost or stolen for personal gain. 

4. Non- Compliance

Non-compliance is a major issue that can lead to heft penalties and even criminal charges. Compliance with specific regulatory standards is compulsory for organizations in every sector. 

Compliances like HIPAA, PCI-DSS, SOC2, ISO 27001, and GDPR ensure that the best security measures are followed by companies in various industries according to global standards. Non-compliance with such standards means that the organizations aren’t reliable and don’t follow the highest standards of data protection and security. 

5. AMIs Made Public

AMIs are Amazon Machine Images that contain all the information required to start a cloud-based storage system. This can include operating systems, data from applications, and more. 

AWS accounts can be accessed and shared making AMIs an extremely vulnerable component of a company’s cloud presence. Such an accident could mean a company’s entire online operational infrastructure could be revealed, making this a costly vulnerability.

Important AWS Cloud Security Services

This section lists some of the important security services provided by AWS to help customers analyze various aspects of their cloud usage. They include: 

1. AWS Identity And Access Management

This service allows one to define and set parameters for access with specific credentials, and to scale the privileges as and when required. It allows you to fine-tune the access and authorization allowing you to decide which individuals, groups, or roles can access certain information. 

The features offered by AWS IAM include 

  • AWS Single Sign-On
  • Manage permissions for single accounts
  • Manage single account roles

2. AWS Macie

AWS Macie is a data protection service offered by AWS to customers. It makes use of machine learning, evaluations, and pattern recognition to identify the sensitive data in your S3 bucket and its accessibility. 

Macie can easily detect changes to a bucket, as well as detect multiple larges files of data including personal information like PII and PHI. It also functions to scan and evaluate one’s S3 environment for security purposes.

3. AWS Artifact 

AWS Artifact helps customers maintain compliance with data privacy and protection standards in place to ensure the safety of sensitive data stored on the cloud. The service helps you understand what sort of regulatory standards are applicable to the data stored by you and provides reports on how to maintain compliance with them. Reports are generally available for SOC, PCI-DSS, GDPR, and more. 

4. AWS CloudHSM

CloudHSM (Hardware Security Module) provided by AWS is a hardware security service that aims to provide easy generation of encryption keys for use on the AWS cloud platform. 

It also allows you to shift your encryption keys to other commercial, standards-compliant HSMs if the configurations set by you allow it. It automates time-taking tasks like hardware provisioning, patching, and availabilities. 

5. AWS Shield

AWS Shield is one of the AWS security services that provide protection to the infrastructure such as network connections. It provides protection against DDoS attacks thus securing the applications running on the AWS cloud. 

AWS Shield is of two types: Standard and Advanced. Standard Shield protects against basic threats like common network DDoS attacks. Advanced Shield goes above and beyond the standard services by also providing identification and prevention of large-scale DDoS attacks, integration, and closely monitored visibility of attacks.

AWS Cloud Security Best Practices

AWS cloud security best practices are those steps that enhance the available security within the AWS cloud when taken. These solutions include:

  • Data Encryption

Encryption is quite important to keep data that is stored and transmitted in the cloud secure from malicious attacks. It is also a security mandate for some regulatory standards without which there would be an issue of non-compliance. 

AWS offers a key management service (KMS) which gives one centralized control over the encryption keys in place. Having data encryption in place ensures that there is an effective security barrier in place against attackers.

  • Data Backup

This is yet another important feature to make use of since if any unmitigated disaster or breach occurs, organizations can get up and running again with a short recovery period owing to the data backups in place. 

AWS Backup is an easy automated way to backup and secures your data from unforeseeable acts that could be natural or manmade. Adding multi-factor authentication to this system will enhance security by limiting the number of individuals who can access and modify the data stored. 

  • Native Cloud Security

Opt for cloud-based security solutions rather than traditional solutions for security since they aren’t entirely equipped to deal with a cloud model. When choosing an AWS security solution for your organization’s data and application, ensure that they can be integrated into your organization’s development pipeline seamlessly. 

They should also have experience providing security solutions to cloud-based organizations such as yours and should be able to detect external threats and vulnerabilities to the applications and sensitive information on the cloud. 

  • Secure Access

Securing access to your organization’s applications and data with the AWS cloud security is crucial to maintaining safety. This can be done by implementing authentication and authorization measures such as multifaceted authentication and implementing role-based access control. 

Making use of strong passwords which should be changed often and, deleting access for inactive accounts are other measures that can help secure access to confidential data within the cloud environment.
