WAF Settings

The following example creates a security group for the sidecars in ns1, ns2 and ns3 namespaces owned by its parent workspace w1 under tenant mycompany, and a security setting that applies the WAF Settings. And the security group and security settings to which this WAF Settings is applied to.

apiVersion: security.tsb.tetrate.io/v2
kind: Group
metadata:
  name: t1
  workspace: w1
  tenant: mycompany
  organization: myorg
spec:
  namespaceSelector:
    names:
    - "*/ns1"
    - "*/ns2"
    - "*/ns3"
  configMode: BRIDGED
---
apiVersion: security.tsb.tetrate.io/v2
kind: SecuritySetting
metadata:
  name: defaults
  group: t1
  workspace: w1
  tenant: mycompany
  organization: myorg
spec:
  waf:
    rules:
      - Include @recommended-conf

In the following examples, the security rule for blocking XSS requests is enabled on Tier1Gateway and IngressGateway respectively, with an ad-hoc debug configuration, instead of the one defined in the security rule.

apiVersion: gateway.xcp.tetrate.io/v2
kind: Tier1Gateway
metadata:
  name: tier1-waf-gw
  group: g1
  workspace: w1
  tenant: mycompany
  organization: myorg
spec:
  workloadSelector:
    namespace: ns1
    labels:
      app: gateway
  passthroughServers:
  - name: nginx
    port: 8443
    hostname: nginx.example.com
  waf:
    rules:
      - Include @owasp_crs/REQUEST-941-APPLICATION-ATTACK-XSS.conf

apiVersion: gateway.xcp.tetrate.io/v2
kind: IngressGateway
metadata:
  name: waf-gw
  group: g1
  workspace: w1
  tenant: mycompany
  organization: myorg
spec:
  workloadSelector:
    namespace: ns1
    labels:
      app: waf-gateway
  waf:
    rules:
      - SecRuleEngine DETECTION_ONLY
      - SecDebugLogLevel 5
      - Include @owasp_crs/REQUEST-941-APPLICATION-ATTACK-XSS.conf
