@ -10,7 +10,7 @@ As part of my {% post_link aws-waf 'routine review' %} of my company's [AWS WAF]
While individual and total WCU are shown during ACL creation/modification on the management console, a read-only role could only check the total WCU. It may be possible to use `CheckCapacity` [CLI](https://docs.aws.amazon.com/cli/latest/reference/wafv2/check-capacity.html) or [API](https://docs.aws.amazon.com/waf/latest/APIReference/API_CheckCapacity.html) by separating each rule as an ACL, but that'll involve excessive (online) API calls.
I further improved my script [waf-acl.py](/files/20210627/waf-acl.py) by implementing _offline_ WCU calculation. While the [AWS docs](https://docs.aws.amazon.com/waf/latest/developerguide/waf-rule-statements-list.html) has a complete list of WCU of each match statement, I find the text transformation part is not clear enough.

I regularly need to audit my company's access control lists (ACLs) implemented in [AWS WAF](https://aws.amazon.com/waf/), as part of my job. Each ACL can be more than a thousand lines which is practically impossible to read. I wrote a script that downloads and summarises the ACLs into human-readable format; each one-thousand-line behemoth is transformed into a fifty-line summary that I can _actually_ audit.
The script is [available here](/files/20210627/waf-acl.py). It currently only supports Cloudfront ACL, feel free to extend it to support regional ACL.
