AWS > CIS v2.0 > 1 - Identity and Access Management > 1.01 - Maintain current contact details

Configures auditing against a CIS Benchmark item.

Level: 1

Ensure contact email and telephone details for AWS accounts are current and map to more than one individual in your organization.

An AWS account supports a number of contact details, and AWS will use these to contact the account owner if activity judged to be in breach of Acceptable Use Policy or indicative of likely security compromise is observed by the AWS Abuse team. Contact details should not be for a single individual, as circumstances may arise where that individual is unavailable. Email contact details should point to a mail alias which forwards email to multiple individuals within the organization; where feasible, phone contact details should point to a PABX hunt group or other call-forwarding system.

AWS > CIS v2.0 > 1 - Identity and Access Management > 1.15 - Ensure IAM Users Receive Permissions Only Through Groups

Configures auditing against a CIS Benchmark item.

Level: 1

IAM users are granted access to services, functions, and data through IAM policies. There are four ways to define policies for a user:
1. Edit the user policy directly, aka an inline, or user, policy;
2. attach a policy directly to a user;
3. add the user to an IAM group that has an attached policy;
4. add the user to an IAM group that has an inline policy.

Only the third implementation is recommended.

AWS > CIS v2.0 > 1 - Identity and Access Management > 1.16 - Ensure IAM policies that allow full ":" administrative privileges are not attached

Configures auditing against a CIS Benchmark item.

Level: 1

IAM policies are the means by which privileges are granted to users, groups, or roles. It is recommended and considered a standard security advice to grant least privilege - that is, granting only the permissions required to perform a task. Determine what users need to do and then craft policies for them that let the users perform only those tasks, instead of allowing full administrative privileges.

Note: This control does not evaluate AWS managed IAM policies since they are not available in Turbot CMDB.

AWS > CIS v2.0 > 1 - Identity and Access Management > 1.19 - Ensure that all the expired SSL/TLS certificates stored in AWS IAM are removed

Configures auditing against a CIS Benchmark item.

Level: 1

To enable HTTPS connections to your website or application in AWS, you need an SSL/TLS server certificate. You can use ACM or IAM to store and deploy server certificates. Use IAM as a certificate manager only when you must support HTTPS connections in a region that is not supported by ACM. IAM securely encrypts your private keys and stores the encrypted version in IAM SSL certificate storage. IAM supports deploying server certificates in all regions, but you must obtain your certificate from an external provider for use with AWS. You cannot upload an ACM certificate to IAM. Additionally, you cannot manage your certificates from the IAM Console.

AWS > CIS v2.0 > 1 - Identity and Access Management > 1.20 - Ensure that IAM Access analyzer is enabled for all regions

Configures auditing against a CIS Benchmark item.

Level: 1

Enable IAM Access analyzer for IAM policies about all resources in each active AWS region.

IAM Access Analyzer is a technology introduced at AWS reinvent 2019. After the Analyzer is enabled in IAM, scan results are displayed on the console showing the accessible resources. Scans show resources that other accounts and federated users can access, such as KMS keys and IAM roles. So the results allow you to determine if an unintended user is allowed, making it easier for administrators to monitor least privileges access. Access Analyzer analyzes only policies that are applied to resources in the same AWS Region.

AWS > CIS v2.0 > 1 - Identity and Access Management > 1.22 - Ensure access to AWSCloudShellFullAccess is restricted

Configures auditing against a CIS Benchmark item.

Level: 1

AWS CloudShell is a convenient way of running CLI commands against AWS services; a managed IAM policy ('AWSCloudShellFullAccess') provides full access to CloudShell, which allows file upload and download capability between a user's local system and the CloudShell environment. Within the CloudShell environment a user has sudo permissions, and can access the internet. So it is feasible to install file transfer software (for example) and move data from CloudShell to external internet servers.

AWS > CIS v2.0 > 2 - Storage > 2.01 - Simple Storage Service (S3) > 2.01.04 - Ensure that S3 Buckets are configured with 'Block public access (bucket settings)'

Configures auditing against a CIS Benchmark item.

Level: 1

Amazon S3 provides Block public access (bucket settings) and Block public access (account settings) to help you manage public access to Amazon S3 resources. By default, S3 buckets and objects are created with public access disabled. However, an IAM principal with sufficient S3 permissions can enable public access at the bucket and/or object level. While enabled, Block public access (bucket settings) prevents an individual bucket, and its contained objects, from becoming publicly accessible. Similarly, Block public access (account settings) prevents all buckets, and contained objects, from becoming publicly accessible across the entire account.

AWS > CIS v2.0 > 5 - Networking > 5.04 - Ensure the default security group of every VPC restricts all traffic

Configures auditing against a CIS Benchmark item.

Level: 2

A VPC comes with a default security group whose initial settings deny all inbound traffic, allow all outbound traffic, and allow all traffic between instances assigned to the security group. If you don't specify a security group when you launch an instance, the instance is automatically assigned to this default security group. Security groups provide stateful filtering of ingress/egress network traffic to AWS resources. It is recommended that the default security group restrict all traffic.

The default VPC in every region should have its default security group updated to comply. Any newly created VPCs will automatically contain a default security group that will need remediation to comply with this recommendation.
