Additional Chart Configurations

Rule Configuration

The rules can be defined in the values of the HelmChart. The syntax and semantic for these rules are quite similar to CascadingRules (See: secureCodeBox | CascadingRules)

To define rules you will have to provide the rules field with one or more matches elements. Each machtes defines one Rule. For example:

rules:  - matches:      anyOf:        - category: "Open Port"          attributes:            port: 23            state: open    override:      severity: "high"      description: "Telnet is bad"

This rule will match all findings with an open port on 23 and override the severity for this finding with high as well as providing a new description Telnet is bad!.

matches

Within the matches you will have to provide anyOf and override. In the anyOf contains one or more conditions to be met by the finding to match the rule. Notice that only one of these elements needs to match the finding for the rule to match.

override

The override field specifies the desired fields and values that need to be updated or added if the rule is matching.
