Cloud Provider Security Showdown: AWS vs Azure vs GCP

Why Cloud Security Matters for Your Business

Cloud security is crucial for the long-term success and growth of your business. Recent research conducted by a leading IT security firm reveals that a staggering 80% of organizations store sensitive data in the cloud. Alarmingly, more than half of these organizations (53%) have experienced a cyberattack on their cloud infrastructure within the past year.

Considering the prevalence and costly consequences of cyberattacks, it is essential to prioritize security features when selecting a cloud service provider. It is vital to fully understand your own security responsibilities in this regard.

In this article, we will explain your security obligations in the cloud and evaluate the advantages and disadvantages of the three major market leaders: Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).

Understanding Your Cloud Security Responsibilities

When you decide to entrust your data to a cloud provider, it’s important to recognize that you can’t completely delegate all of your security obligations. While cloud providers assume certain security responsibilities, there are still areas where you retain accountability.

This concept is known as the “shared responsibility model.” While cloud providers are responsible for securing their physical infrastructure and the core service, they also have obligations to fulfill regarding crucial security, governance, and compliance requirements.

To provide you with a general overview, here’s a simplified guide on how this shared responsibility model operates.

Understanding Your Roles in Cloud Security

To put it simply, your cloud provider’s role is to ensure the overall security of the cloud infrastructure. On the other hand, your responsibility lies in maintaining security within the cloud as you utilize it.

Let’s take an example to clarify this further. Your cloud provider should have measures in place to safeguard against brute-force login attempts, which are common security threats. However, when it comes to mitigating risks arising from user mistakes or malicious actions, the onus is on you to take appropriate measures.

In summary, your cloud provider handles the security of the cloud itself, while you play a crucial role in minimizing threats and ensuring security while using the cloud services.

Comparing AWS, Azure, and GCP: What Sets Them Apart?

When it comes to the top cloud service providers, namely AWS, Microsoft Azure, and GCP, they collectively dominate 62% of the market and have experienced significant growth of 42% in the first quarter of 2022. This surge in popularity can be attributed to the accelerated digitization caused by the COVID pandemic and the heightened focus on security.

While each provider has its own strengths and unique offerings, all three prioritize security and provide robust features to safeguard your organization and its valuable data. Regardless of the provider you choose, you can expect strong performance in the following key areas:

1. Firewall: A virtual barrier that carefully monitors incoming and outgoing network traffic, blocking any suspicious activity.
2. Encryption in transit: Data encryption that ensures the protection of your information as it moves between your network and the cloud provider’s services or between different services within the cloud.
3. Compliance management: Certification for major compliance standards, along with features that assist users in remaining compliant with data regulations like the GDPR.
4. IaaS DDoS protection: Specialized features designed to fend off Distributed Denial of Service (DDoS) attacks, including software detectors and scalable bandwidth to handle sudden surges in traffic. AWS refers to their offering as ‘DDOS Protection,’ Azure’s is known as ‘Shield,’ and GCP offers ‘Google Cloud Armor.’
5. Physical security: Stringent measures implemented by cloud providers to ensure the physical security of their servers, including security personnel and advanced alarm systems.

Although there are differences among AWS, Azure, and GCP, all three providers prioritize the crucial aspects of cloud security to offer you a reliable and protected computing environment.

Amazon Web Services (AWS): A Reliable Cloud Service Provider

Among the three market leaders, Amazon Web Services (AWS) holds the distinction of being the oldest and most widely adopted cloud service provider. It enjoys immense popularity due to its comprehensive documentation and secure default configurations, making it a preferred choice for many organizations.

Shared Responsibility Model of AWS

AWS follows a straightforward and user-friendly shared responsibility model, aligning closely with the concept of “security in/of the cloud.” Under this model, AWS takes responsibility for crucial aspects such as hardware, storage, networking, and databases. On the other hand, customers are responsible for implementing their own security practices for data protection, managing user access, and handling third-party applications.

In essence, AWS provides a solid foundation of security measures within their cloud infrastructure, while customers have the flexibility and responsibility to establish and maintain security practices that align with their specific needs and requirements.

AWS Strengths and Considerations Simplified

Amazon Web Services (AWS) excels in several areas as a mature cloud provider:

1. Clear and Accessible Documentation: AWS provides easily understandable and transparent documentation, making it simple to find the information you need.
2. Extensive Tooling: AWS offers a wide range of tools and boasts the largest marketplace for third-party add-ons, providing a rich ecosystem of options.
3. Abundance of IT Security Professionals: AWS has a larger pool of IT security professionals with experience in their platform compared to Azure or GCP, making it easier to find skilled personnel.
4. Mature Partner Network: AWS has an extensive and well-established network of partners, offering additional support and services.

AWS prioritizes security by default, employing secure configurations in key areas. For example, when deploying an instance on a Virtual Private Cloud (VPC), access is automatically restricted.

AWS’ auditing tool, CloudTrail, simplifies compliance management, enhances security posture, and consolidates activity records across different regions and accounts.

However, there are a few points to be aware of:

1. User Access Management Complexity: Managing user access at an enterprise level on AWS requires a more significant commitment of resources due to their approach and reliance on isolation as a security measure.
2. VPN Offerings Comparison: Microsoft Azure has a slightly stronger VPN offering, particularly regarding site-to-site connections. While both AWS and Azure support point-to-site and site-to-site options, Azure’s site-to-site connection limit is 30, while AWS’s limit is 10.

Understanding these strengths and considerations will help you make informed decisions when considering AWS as your cloud service provider.

Microsoft Azure: Simplifying the Key Points

Microsoft Azure is the second most established cloud service provider after AWS. While its centralized approach can benefit certain organizations, it has some drawbacks such as a less defined shared responsibility model and consistency issues that can be frustrating.

Shared Responsibility Model:

Azure’s shared responsibility model is similar to AWS but includes an additional “gray area” where responsibilities depend on the deployed cloud model. This encompasses infrastructure, directory infrastructure, applications, network controls, and operating systems.

Strengths of Azure:

• Centralized Identity and Access Management (IAM): Azure’s Active Directory offers a streamlined approach to IAM, allowing you to manage authorization and permissions from a single console, reducing management complexity and minimizing human error.
• Comprehensive Activity Logs: Azure’s activity logs cover console and API activity across the entire organization by default, providing a clear overview. Additionally, local teams can manage their own alerts through Azure Security Center.
• Built-in Privileged Access Management: Azure offers built-in privileged access management, providing just-in-time access to Azure AD and Azure Resources without the need for third-party add-ons, unlike AWS and GCP.
