comparison

The condition to apply to the key value when filtering Security Hub findings with a map filter. To search for values that have the filter value, use one of the following comparison operators:

• To search for values that include the filter value, use `CONTAINS`. For example, for the `ResourceTags` field, the filter `Department CONTAINS Security` matches findings that include the value `Security` for the `Department` tag. In the same example, a finding with a value of `Security team` for the `Department` tag is a match.

• To search for values that exactly match the filter value, use `EQUALS`. For example, for the `ResourceTags` field, the filter `Department EQUALS Security` matches findings that have the value `Security` for the `Department` tag. `CONTAINS` and `EQUALS` filters on the same field are joined by `OR`. A finding matches if it matches any one of those filters. For example, the filters `Department CONTAINS Security OR Department CONTAINS Finance` match a finding that includes either `Security`, `Finance`, or both values. To search for values that don't have the filter value, use one of the following comparison operators:

• To search for values that exclude the filter value, use `NOT_CONTAINS`. For example, for the `ResourceTags` field, the filter `Department NOT_CONTAINS Finance` matches findings that exclude the value `Finance` for the `Department` tag.

• To search for values other than the filter value, use `NOT_EQUALS`. For example, for the `ResourceTags` field, the filter `Department NOT_EQUALS Finance` matches findings that don’t have the value `Finance` for the `Department` tag. `NOT_CONTAINS` and `NOT_EQUALS` filters on the same field are joined by `AND`. A finding matches only if it matches all of those filters. For example, the filters `Department NOT_CONTAINS Security AND Department NOT_CONTAINS Finance` match a finding that excludes both the `Security` and `Finance` values. `CONTAINS` filters can only be used with other `CONTAINS` filters. `NOT_CONTAINS` filters can only be used with other `NOT_CONTAINS` filters. You can’t have both a `CONTAINS` filter and a `NOT_CONTAINS` filter on the same field. Similarly, you can’t have both an `EQUALS` filter and a `NOT_EQUALS` filter on the same field. Combining filters in this way returns an error. `CONTAINS` and `NOT_CONTAINS` operators can be used only with automation rules. For more information, see Automation rules in the User Guide.
