Component: aws-inspector

This component is responsible for provisioning an AWS Inspector by installing the Inspector agent across all EC2 instances and applying the Inspector rules.

AWS Inspector is a security assessment service offered by Amazon Web Services (AWS). It helps you analyze and evaluate the security and compliance of your applications and infrastructure deployed on AWS. AWS Inspector automatically assesses the resources within your AWS environment, such as Amazon EC2 instances, for potential security vulnerabilities and deviations from security best practices.

Here are some key features and functionalities of AWS Inspector:

  • Security Assessments: AWS Inspector performs security assessments by analyzing the behavior of your resources and identifying potential security vulnerabilities. It examines the network configuration, operating system settings, and installed software to detect common security issues.

  • Vulnerability Detection: AWS Inspector uses a predefined set of rules to identify common vulnerabilities, misconfigurations, and security exposures. It leverages industry-standard security best practices and continuously updates its knowledge base to stay current with emerging threats.

  • Agent-Based Architecture: AWS Inspector utilizes an agent-based approach, where you install an Inspector agent on your EC2 instances. The agent collects data about the system and its configuration, securely sends it to AWS Inspector, and allows for more accurate and detailed assessments.

  • Security Findings: After performing an assessment, AWS Inspector generates detailed findings that highlight security vulnerabilities, including their severity level, impact, and remediation steps. These findings can help you prioritize and address security issues within your AWS environment.

  • Integration with AWS Services: AWS Inspector seamlessly integrates with other AWS services, such as AWS CloudFormation, AWS Systems Manager, and AWS Security Hub. This allows you to automate security assessments, manage findings, and centralize security information across your AWS infrastructure.


Stack Level: Regional

Here's an example snippet for how to use this component.

enabled: true
- cis

The aws-inspector component can be included in your Terraform stack configuration. In the provided example, it is enabled with the enabled variable set to true. The enabled_rules variable specifies a list of rules to enable, and in this case, it includes the cis rule. To simplify rule selection, the short forms of the rules are used for the enabled_rules key. These short forms automatically retrieve the appropriate ARN for the rule package based on the region being used. You can find a list of available short forms and their corresponding rule packages in the var.enabled_rules input documentation.

For a comprehensive list of rules and their corresponding ARNs, you can refer to the Amazon Inspector ARNs for rules packages documentation. This resource provides detailed information on various rules that can be used with AWS Inspector and their unique identifiers (ARNs).

By customizing the configuration with the appropriate rules, you can tailor the security assessments performed by AWS Inspector to meet the specific requirements and compliance standards of your applications and infrastructure.

additional_tag_mapAdditional key-value pairs to add to each map in tags_as_list_of_maps. Not added to tags or id.
This is for some rare cases where resources want additional configuration of tags
and therefore take a list of maps with tag key, value, and additional configuration.
attributesID element. Additional attributes (e.g. workers or cluster) to add to id,
in the order they appear in the list. New attributes are appended to the
end of the list. The elements of the list are joined by the delimiter
and treated as a single ID element.
contextSingle object for setting entire context at once.
See description of individual variables for details.
Leave string and numeric variables as null to use default value.
Individual variable settings (non-null) override settings in context object,
except for attributes, tags, and additional_tag_map, which are merged.
"additional_tag_map": {},
"attributes": [],
"delimiter": null,
"descriptor_formats": {},
"enabled": true,
"environment": null,

"labels_as_tags": [
"name": null,
"namespace": null,
"regex_replace_chars": null,
"stage": null,
"tags": {},
"tenant": null
delimiterDelimiter to be used between ID elements.
Defaults to - (hyphen). Set to "" to use no delimiter at all.
descriptor_formatsDescribe additional descriptors to be output in the descriptors output map.
Map of maps. Keys are names of descriptors. Values are maps of the form
{<br/> format = string<br/> labels = list(string)<br/>}
(Type is any so the map values can later be enhanced to provide additional options.)
format is a Terraform format string to be passed to the format() function.
labels is a list of labels, in order, to pass to format() function.
Label values will be normalized before being passed to format() so they will be
identical to how they appear in id.
Default is {} (descriptors output will be empty).
enabledSet to false to prevent the module from creating any resourcesboolnullno
enabled_rulesA list of AWS Inspector rules that should run on a periodic basis.

Valid values are cve, cis, nr, sbp which map to the appropriate Inspector rule arns by region.
environmentID element. Usually used for region e.g. 'uw2', 'us-west-2', OR role 'prod', 'staging', 'dev', 'UAT'stringnullno
id_length_limitLimit id to this many characters (minimum 6).
Set to 0 for unlimited length.
Set to null for keep the existing setting, which defaults to 0.
Does not affect id_full.
label_key_caseControls the letter case of the tags keys (label names) for tags generated by this module.
Does not affect keys of tags passed in via the tags input.
Possible values: lower, title, upper.
Default value: title.
label_orderThe order in which the labels (ID elements) appear in the id.
Defaults to ["namespace", "environment", "stage", "name", "attributes"].
You can omit any of the 6 labels ("tenant" is the 6th), but at least one must be present.
label_value_caseControls the letter case of ID elements (labels) as included in id,
set as tag values, and output by this module individually.
Does not affect values of tags passed in via the tags input.
Possible values: lower, title, upper and none (no transformation).
Set this to title and set delimiter to "" to yield Pascal Case IDs.
Default value: lower.
labels_as_tagsSet of labels (ID elements) to include as tags in the tags output.
Default is to include all labels.
Tags with empty values will not be included in the tags output.
Set to [] to suppress all generated tags.
The value of the name tag, if included, will be the id, not the name.
Unlike other null-label inputs, the initial setting of labels_as_tags cannot be
changed in later chained modules. Attempts to change it will be silently ignored.
nameID element. Usually the component or solution name, e.g. 'app' or 'jenkins'.
This is the only ID element not also included as a tag.
The "name" tag is set to the full id string. There is no tag with the value of the name input.
namespaceID element. Usually an abbreviation of your organization name, e.g. 'eg' or 'cp', to help ensure generated IDs are globally uniquestringnullno
regex_replace_charsTerraform regular expression (regex) string.
Characters matching the regex will be removed from the ID elements.
If not set, "/[^a-zA-Z0-9-]/" is used to remove all characters other than hyphens, letters and digits.

stageID element. Usually used to indicate role, e.g. 'prod', 'staging', 'source', 'build', 'test', 'deploy', 'release'stringnullno
tagsAdditional tags (e.g. {'BusinessUnit': 'XYZ'}).
Neither the tag keys nor the tag values will be modified by this module.
