How to establish a cloud security architecture, I believe that many inexperienced people are helpless about this, this article summarizes the causes and solutions of the problem, through this article I hope you can solve this problem.

Cloud Security Challenges

Cloud security presents unique challenges for organizations. Here are some of the main challenges you should consider when designing your cloud security architecture:

Identity and access: Cloud systems are insecure by default, making it easy for employees to create resources on the cloud unattended. All cloud providers offer strong identity and Access Management (IAM) capabilities, but it's up to the organization to set them up correctly and apply them consistently across all workloads.

Unsecure APIs: Everything in the cloud has an API that is both powerful and extremely dangerous. An API that is not adequately protected or uses weak authentication could allow an attacker to access and control the entire environment. API is the front door to the cloud, which is usually open.

Misconfiguration: Cloud environments have a large number of moving parts, including compute instances, buckets, databases, containers, and serverless capabilities. Most of them are transient, with new instances starting and closing daily. Any of these resources can be misconfigured, allowing attackers to access them over public networks, expose data, and cause damage to critical systems.

Compliance risk: You must ensure that your cloud provider supports all relevant compliance requirements and understand what controls and services you can use to meet your compliance obligations.

Stealth Control Plane: In clouds, control planes are not controlled by the organization. While cloud providers are responsible for the security of their infrastructure, they do not provide information about data flow and internal architecture, meaning security teams are flying blind.

Tips for Building a Cloud Security Architecture

Here are some tips to help you build a reliable cloud security architecture.

1. conduct due diligence

Before migrating to a cloud provider or expanding cloud deployments to other cloud providers, organizations should carefully investigate the security and resiliency attributes of the entire cloud provider and the specific services they intend to use.

The due diligence process should include:

Define safety and availability benchmarks based on data from peer organizations

Discover cloud provider security best practices and their impact on organizations

Try cloud provider security features such as encryption, logging, and identity and Access Management (IAM)

Find out how a cloud provider can help meet your compliance obligations and the criteria for its certification

Learn the details of your cloud provider's shared responsibility model and what security elements your organization is responsible for

Evaluate first party security services (provided by cloud platforms) and compare them to third party alternatives

Assess whether existing security tools are relevant to the new cloud environment

2. Determine which data is most sensitive

For most organizations, it is not feasible to apply strict security measures to all data. Some data may still be insecure, but you must determine which categories of data must be protected to prevent breaches and compliance violations. Using data detection and classification to understand what you need to protect is critical.

This is usually done using automatic data classification engines. These tools are designed to find sensitive content across networks, endpoints, databases, and clouds, enabling organizations to identify sensitive data and establish the necessary security controls.

3. Get employee cloud usage out of the shadows

Just because you have an enterprise cloud security policy doesn't mean employees will adhere to it. Employees rarely consult IT before using common cloud services such as Dropbox or web-based email.

An organization's Web proxy, firewall, and SIEM logs are good resources to measure employee shadow usage of the cloud. These can provide a comprehensive view of what services are being used and by which employees. As you discover shadow cloud usage, you can assess the added value of services based on the risks they pose. You can choose to "legalize" shadow cloud services, or you can crack down and take steps to ban them.

Another aspect of shadow usage is accessing legitimate cloud resources from untrusted endpoint devices. Because any device connected to the Internet can access any cloud service, personal mobile devices can create a gap in your security policy. To prevent data from escaping from trusted cloud services to unmanaged devices, device security authentication is required before access is enabled.

4. Protect Cloud Point

Many organizations are deploying endpoint protection platforms with multiple layers of protection, including endpoint detection and response (EDR), next-generation antivirus (NGAV), and user and entity behavior analytics (UEBA).

Endpoint protection is even more important in the cloud. In the cloud, endpoints are compute instances, storage volumes and buckets, and managed services such as Amazon RDS.

Cloud deployments have a large number of endpoints that change more frequently than on-premises and therefore require a higher level of visibility. Endpoint protection tools help organizations control their cloud workloads and protect the weakest links in their security posture.

5. Understand your role in compliance obligations

Remember that compliance is ultimately the sole responsibility of your organization. No matter how much business functionality you move to the cloud, you can choose a cloud architecture platform to help you comply with all regulatory standards applicable to your industry, whether PCI DSS, GDPR, HIPAA, CCPA, or any other standard or regulation.

Learn about the tools and services your cloud provider offers to ensure compliance, and what third-party tools you can use to create compliant cloud systems that can be audited to prove compliance.
