Create `include/check_creds_last_used` and move all logic for checking last usages of passwords and access keys there
Modify check13 and extra774 to call new function, specifying time-range of last 90 days and last 30 days respectively
Modify messages in check14 and check121 so that all mentions of 'access key's are consistent
Fixes#496
Remove the second entry in any comma-separated check IDs from each check, formatting
the check ID with leading zeros in `include/outputs` if the `-n` flag is active
- Move Security Hub related code to a dedicated include/securityhub_integration file
- Check that Security Hub is enabled in the target region before beginning checks when -S is specified
- Add error handling to the batch-import-findings call
- Add CHECK_ASFF_TYPE variables to all CIS checks to override the default
- Add support for CHECK_ASFF_RESOURCE_TYPE variables which override the default 'AwsAccount' value for the resource a finding relates to.
- Add CHECK_ASFF_RESOURCE_TYPE variables to all checks where there is a suitable value in the schema
- Remove json-asff output for info messages as they are not appropriate for possible submission to Security Hub
- Update the README to cover Security Hub integration
- Add an IAM policy JSON document that provides the necessary BatchImportFindings permission for Security Hub
- Remove trailing whitespace and periods in pass/fail messages to be consistent with the majority of messages, to prevent future tidy-up from changing the finding IDs
json-asff mode outputs JSON, similar to the standard 'json' mode with one check per line, but in AWS Security Finding Format - used by AWS Security Hub
Currently uses a generic Type, Resources and ProductArn value, but sets the Id to a unique value that includes the details of the message, in order to separate out checks that run against multiple resources and output one result per resource per check. This ensures that findings can be updated, should the resource move in or out of compliance
securityhub mode generates the ASFF JSON and then passes it to an 'aws securityhub batch-import-findings' call, once per resource per check. Output to the screen is similar to the standard mode, but prints whether or not the finding was submitted successfully
Fixes#524
