As an example, we will be focusing on the AWS cloud for this blog post to illustrate the various steps and considerations involved in conducting a cloud security configuration review.
What is Cloud Security
Cloud security is a critical concern for organizations using cloud platforms such as Amazon Web Services (AWS) or Microsoft Azure, Google Cloud Platform (GCP), and other Cloud Platforms. These platforms provide a range of security measures to help protect data and applications, including access controls, network security, and data protection. However, it is important for organizations to also implement their own security measures and perform regular reviews to ensure that their cloud configurations are secure. This can include setting up multi-factor authentication, implementing encryption, and regularly updating security policies and controls. By taking a proactive approach to cloud security, organizations can ensure that their data and applications are protected in the cloud and comply with relevant laws and regulations.
Overall, AWS, Azure, and GCP offer comprehensive security measures to help protect data and applications in the cloud. It is important for organizations using these platforms to regularly review and update their security configuration to ensure that it remains effective at protecting against potential threats.
Why Companies should do a cloud security configuration review
Cloud security configuration reviews are crucial for companies to ensure that their data and systems are protected from potential security threats. These reviews allow companies to identify any vulnerabilities in their cloud systems and take the necessary steps to address them before they can be exploited by cybercriminals.
Additionally, regular cloud security configuration reviews can help companies stay compliant with industry regulations and standards, such as the Payment Card Industry Data Security Standard (PCI DSS) and the Health Insurance Portability and Accountability Act (HIPAA). By conducting these reviews, companies can also minimize the risk of data breaches and protect their reputation and brand trust. Overall, investing in cloud security configuration reviews is a smart business decision that can help companies ensure the security of their sensitive data and systems.
Perquisites before starting the security review
To ensure the success of a cloud security review, it’s important to have all necessary prerequisites in place. This includes assembling the review team, gathering relevant documentation, identifying the scope of the review, and gathering the appropriate Credentials. By preparing in advance, you can ensure that the review is comprehensive and effective at identifying and addressing any potential vulnerabilities or threats to your cloud environment.
Involve the appropriate stakeholders
This means ensuring that the people who are responsible for the security of the AWS environment are involved in the review process. This could include security professionals, such as security engineers or administrators, as well as application owners and network administrators.
Involving these stakeholders is important for several reasons. First, it ensures that all relevant parties are aware of the review and can provide input or feedback. This can help to identify any potential risks or vulnerabilities that might have been missed by the review team. Second, involving the appropriate stakeholders allows for a more comprehensive review of the security configuration. Security professionals can provide insight into best practices and identify any potential weaknesses in the configuration, while application owners and network administrators can provide a deeper understanding of how the system is used and how it is configured.
Gather relevant documentation
This includes any documents that provide information about the current security posture of the AWS environment, such as security policies and procedures, network diagrams, and access control lists.
Having this documentation on hand can be helpful in understanding the current security posture and identifying any potential vulnerabilities or areas for improvement. It can also provide context for the review process and help to ensure that all relevant aspects of the security configuration are considered.
Credentials to access AWS Environment
If you want to perform a security configuration review on your Amazon Web Services (AWS) account, you will need two things: access keys and an AWS account with a security auditor role. Access keys are unique combinations of a user-defined access key ID and a secret access key that are used to sign programmatic requests made to AWS. They allow you to authenticate your identity and access AWS resources. In addition, AWS access keys are also required to run the automated tools.
On the other hand, the security auditor role is a special type of AWS Identity and Access Management (IAM) role that grants permissions to perform security-related tasks on your AWS account. This includes reviewing security configurations, identifying vulnerabilities, and implementing security best practices.
Identify the Scope of the review
This involves determining which resources within the AWS environment will be included in the review. These resources could include Elastic Compute Cloud (EC2) instances, Simple Storage Service (S3) buckets, Relational Database Service (RDS) databases, and any other assets that are relevant to the review.
It is essential to clearly define the scope of the review before proceeding, as this will help ensure that all relevant assets are included and that the review is comprehensive. It will also help to ensure that the review is focused and efficient, as it will allow you to prioritize the assets that are most important to the organization.
List Deployed Resources using Tag Editor
To extract a list of all AWS resources deployed in an AWS environment, the AWS Tag Editor can be used. The following steps can be followed to do so:
- Sign in to the AWS Management Console.
- Navigate to the Tag Editor in the resource groups section of the AWS Management Console.
- In the “Regions” dropdown menu, select the region you want to list. [Recommended: All regions]
- In the “Resource type” dropdown menu, select the type of resources you want to list. [Recommended: All supported resource types]
- In the Filter by tag field, enter the name and value of the tag that you want to use to filter the resources. [Recommended: Leave the fields empty]
- Click the “Search resources” button to view the resources that match the specified selection.
- To view the details of a resource, click on the resource in the list.
- Click on the “Export resources to CSV” dropdown menu and select “Export all tags”.
- Now the “resources.csv” file will be downloaded to your local machine.
The CSV file generated by the Tag Editor can be used to locate the deployed resources in your AWS account and navigate to specific regions and resource types for the cloud security review. The file will contain a list of the resources, their resource IDs, resource types, and region, as well as any tags that have been applied to the resources. This information can be helpful in identifying the resources that are relevant to your review and locating them in the AWS Management Console.
