waf-automations-cdk

Usage

const wafAutomations = new WafSecurityAutomations(this, 'waf-security-automations', {
    stackName: 'waf-security-automations',
    accessLogBucket: myLogBucket,
    options: {
        // See below
    },
});

// Can now use the following:
wafAutomations.webAclName  // string, the name of the created webAcl, will match stackName due to implementation of the cfn template
wafAutomations.webAclArn  // string, arn of the created webAcl, pass this to a Cloudfront distribution
wafAutomations.webAclId   // string
wafAutomations.webAclDescription  // string

This creates a WAFv2 WebACL named matching the stackName.
