Each week, we highlight a community member who's contributing to Wafris and share some of our technical progress.
We're excited to combine these this week, as Agustin Cavillotti reported some unusual Redis behavior. This report led us to track down a recurring bug bloating the overall memory needed for a Wafris instance.
The amount of excess memory consumed varies by the number and uniqueness of requests to a site, so it isn't easy to nail down a percentage improvement. Still, in many cases, we're seeing sites using half as much memory as previously.
As of this update, we've updated all of the following clients to a new, more efficient expiration process:
Ruby/Rails - https://github.com/Wafris/wafris-rb
Laravel - https://github.com/Wafris/laravel-wafris
Node - https://github.com/Wafris/node-wafris
Caddy- https://github.com/Wafris/wafris-caddy
Something surprising that we've found in building Wafris is the breadth of what people consider a "Web Application Firewall" (WAF).
Everything from a dozen regexes tucked into their web framework to globally spanning networks. We're for whatever works for people, but wanted a shared understanding of the features, uses, and options for WAFs, so we put together a guide covering almost everything you'd need to know at:
https://wafris.org/guides/developers-guide-to-web-application-firewalls
GraphQL has become increasingly popular with developers and now also with attackers. We've detected multiple bots scanning sites specifically for GraphQL tools, endpoints, and data scraping.
It's easy to fake a user agent in a web request, so how can you be sure it's actually Googlebot crawling your site and not a malicious bot looking for vulnerabilities or scraping your site?
In Wafris Hub, click on any grade, and you'll get a full IP ownership and reputation rundown in our publicly available IP lookup service.
The IP Lookup is also available at: https://wafris.org/ip-lookup
If you're using Node/Express and want to try out Wafris, we're in beta with the middleware and would love to have a few more testers. If this is you, hit Reply, and we'll set you up.
Not a Node/Express user? We're actively working on more integrations and would love to hear what you're using, any security concerns you may have, and how we can help.
