Hi mate, u can setup cloudflare bouncer to have crowdsec blacklist shared up to the cloudflare layer. Using it for enterprises u can ask cloudflare to have more than just 10000 ip addresses configured as a list (they raised me to 20k). After some months a bit of improvement is reached that way. Happy hardening u all 🎉

It would be great if you can revisit this video, since now traefik has an official plugin, the hub auto update itself (no cron needed), the dashboard looks cool, they have a centralized way to manage multiple instances, they added appsec WAF integration and probably more. There arent't many recent tutorials and you're always spot on with yours.

[@pewter77]

I just set this up, be aware that if you're running behind a reverse proxy like cloudflare the traefik bouncer here doesn't use the correct IP address due using the incorrect header value.

[@TechnoTim]

I noticed that too and there is a PR out there for it. According the CrowdSec though, CloudFlare IPs are on their global allow list so they can’t be blocked. Hopefully the PR gets merged to look at the real ip in the header

[@pewter77]

@@TechnoTim The main problem isn't cloudflare IPs getting banned, it's that the bouncer doesn't block anything because it reads the headers and asks CrowdSec for information on the wrong IP. The PR is mine, I'm running it currently on my machine and it works well so hopefully the dev comes back soon!

[@TechnoTim]

Ah! Nice! Thank you! I have been watching that issue! Looks like it was merged!

[@Calvin420GetRektM8]

One thing, that you still dont follow: you dont capsule your services from another. You just use ONE network: "Proxy" if you want to protect your services even more, you should create seperate containers between the traefik and services like heimdall and co.

[@TechnoTim]

Thanks! I break up my compose files. Also, don't all services that are served through he reverse proxy need to be on the same docker network to proxy through?

In europe stuff like this is always a pain to check if it is in line with GDPR

Hey Techno, amazing video! I was really exciting when I managed to config Crowd for read the traefik logs. I have a question unu Is it possible to configure Crowdsec to allow the connection from a specific origin, and ignore or prevent access to my service from other origins different from the domain I defined? The context is that I need to secure a backend that is exposed to the internet via traefik and an external frontend needs to consume it.

[@MichaelKliewe]

I guess I would have started the bouncer before crowdsec, so that it's available when crowdsec starts up. Which means: crowdsec should depend on the bouncer. Am I wrong?

[@crowdsec]

No since you can run everything distributed on different servers. You can have one agent receving logs from multiple other servers and controlling bouncers on remote firewalls, even across operating systems. So we can't depend the installation of the bouncer in the agent. And that is by design :-)

[@klauss35]

Are you planning to do a crowdsec nginx proxy manager video tutorial? awesome video by the way but sadly i don't use treafik

[@crowdsec]

You should join our Discord and ask about the Grafana stuff if you want fast help. Also you can setup a number of notifications on CrowdSec when a scenario triggers. So basically your DDoS scenario would trigger an alert which would then be sent to your phone. No problem with CrowdSec.

How did you get Cloudflare to forward the real IP? In your case if you use Cloudflare which I think you do, the ban only worked because you have a local DNS. Banning your IP would otherwise do nothing because traefik and hence crowdsec would always see the Cloudflare IP assuming you have reverse proxy set up in CF

[@ChrisDePasqualeNJ]

Hey Tim, great video appreciate all your hard work. I've been trying to install crowd sec for some time now in my environment. I have two raspberry pi's one 32 bit and one 64 bit. Crowd sec has given some instructions on how to install on arm but my Linux skills are lacking and well they don't show us like you do. Also I don't use traffic I use nginx reverse proxy. Should I even try or should I keep waiting for someone to make a video specifically for raspberry pi crowd sec with Nginx and docker.

[@dermuschelschluerfer]

I wouldnt run an ips firewall on a raspberry pi. Its like showing everyone you have a tank in the garden to defend your country but in reality that tank is just out of cardboard. The performance wont hold up.

[@philippehumeau7972]

The most likely place to find help on this topic is CrowdSec discourse server or the discord one (just google them)

[@koevoet7288]

Why dont you just use bind mounts instead of docker volumes? Aren’t binds easier to use and backup?

[@TechnoTim]

I did bind mount the only thing I want backed up, the config. The rest (like logs) is in a docker volume which I don't care too much about. Also, their docs say to do it like this and I had issues trying to bind locally.

[@howling-wolf]

wait in the end it sounds like i have to manually add ips to the descsions list. I thought this is an automatic thing that bans any IP that appears SUS to my instance or is already known to be sus.

[@danielcronk739]

Thanks for the great tutorial and video. I've leared a lot from you over the last few months. After working through this and installing I have a question I'd like your input on. When proxying through Cloudflare, crowdsec is analyzing the Cloudfare IP, not the real IP of the client. Now I can imagine how this may be useful if someone decides to attack the IP directly or somehow gets around Cloudflare (I can't even begin to imagine how that's even possible), but I have my firewall to only accept connections from Cloudflare IPs on 80/443. So in that instance, can you still see any benefit to crowdsec? I know there are some complicated ways to have traefik be able to see the real IP from Cloudflare, but I haven't attempted that yet.

[@TechnoTim]

I think there is a PR out there to fix this!

[@ColinEditz]

Hi Daniel, I appreciate the kind of higher level thinking of your comment. I have the exact same setup in regard to Cloudflare and only accepting Cloudflare IPs on 80/443, and had not thought of this yet. I wonder if you have done any more thinking about this. Are you still running Crowdsec or have you deemed it unnecessary? I see there is also a Cloudflare-Bouncer, which seems to take a different approach and updates your firewall settings in Cloudflare itself. Curious to hear what you think.

[@manuelthallinger7297]

The Core Question for me is, can i make Trafik work behind an HaProxy. I have atm a haproxy running in my pfsense and i would like to keep that, but trafik with crowdsec would be a nice addition? What IP does Crowdsec ban ? For example can i tell it to ban cf-connecting-ip ?

[@philippehumeau7972]

well here you can use crowdsec with opnsense, ha proxy, nginx or as a container so quite some flexibility :) Ip are banned base on the sightings of all user of the community and curated by CrowdSec to avoid false positives and poisoning.

[@manuelthallinger7297]

@@philippehumeau7972 Played around with it, atm still behind my haproxy and works well. I noticed some problems over the time with running software behind cloudflare. Some software is intelligent enough to recognize the real ip ( it can be seen through the CF-Connecting-IP Header), some just see the Cloudflare IP and the last thing I would want it to do is to block the Cloudflare ips =) the only thing really missing from traefik is brotli, but that's just personal preference

[@krishnegowdaa.h2271]

When I'm using CF proxy how to get real ip to crowdsec ?

[@festro1000]

Sounds great, but this is not only open sourced but the database is managed by the community; what's to stop bad actors from listing valid sites as malicious? wouldn't that make this it's own kind of ddos attack if people can't access a site because someone fraudulently added it to a block list?

[@crowdsec]

That's a good question. Very shortly described it's based on trust level but servers who report; the longer time they have sine so reliably, the higher trust ranking and the more do they count when determining wheter an IP is bad or not. Also, an ASN only gets one count. All this and more exists to make poisioning as expensive and hard as possible. If you have more questions, feel free to go to our Discord.

[@festro1000]

@@crowdsec Ok thanks, a few more things to consider would be oversight, I read that a university was banned despite making years of commits to Linux for posting some intentionally bad commits, and you said that an ASN only gets one count are their measures taking botnets into consideration? because I can't imagine it would be hard for someone with a large botnet spoofing an address to make it seem malicious.

[@crowdsec]

@@festro1000 Where was the university banned? Was this in relation to CrowdSec? No, we're only taking their actual behaviour in terms of how realiably they send signals into consideration. Could you elaborate on the spoofing part?

[@zedzed4238]

I always see these videos with crowd-sec, fail2ban, etc, and I want to add these to my setup, but what I always see left out is the explanation of what happens to self-hosted content that isn't accessed exclusively from a browser? Like emby/plex wallabag bitwarden, etc, that have a mobile app integration and even a possible chrome extension? Do they just break unless the app-code is specifically built to work with it? because it seems like crowdsec and f2b work by placing a sort of http "basic-auth" layer in front of it and forwarding the creds to the app and then logging the apps response and sifting through those logs with the bouncers etc, unless I misunderstood that, and if that's the case, what if the chrome extensions for bitwarden and the mobile apps for emby/plex aren't setup to expect that middleware layer between the emby server and the mobile app? For example, does the bitwarden mobile app need to be specifically developed to expect that middleware layer or is it a seemless interception of the creds the mobile app passes to what it thinks to be the bitwarden server and is in reality the traefik/crowdsec middleware? An alternative would be if the middleware just passes through traffic that has http-headers/user agent strings that identify it as a mobile app to maintain compatibility because it doesn't deal with mobile apps, but what stops bots from just using that user-agent string to bypass the middleware if that's how it works? Again If anyone has experience with this i'd love to hear any explanations or corrections of misunderstandings i might have. It's one of those things that i've searched the docs for but it seems like i won't know it it works or not until i attempt it unless someone else has already and can share their experience

There is a possibility to use bgp flow to your advantage, but I don't know a single home internet provider who supports it and even then it's really limited

And against brute force attacks and vulnerability scanning you should just use WAF for public services and VPN server for maintenence and stuff

I did many try to connect on my phone but no log in traefik yet when I want to see the log of the authelia application I can see the log : Unsuccessful 1FA authentication attempt by user '' and so far CS did not decide to block those try ! so it's great to block already known IPs I looking forward to an update so we can add authelia in the survey of CS :) I already found the collection and configuration now I need to put that togather and add a new aquisition in the list, but that part is a bit clouded for 1 folder it's clear, cristal clear, but can I add other foler with other labels... and what abount a bouncer for that app? may be it's not needed cause the app that will block is traefik; I'ld like to get the logs of the server hosting docker to be analysed too; to be sure no brute force will be attempted on my ssh even if I'm a no password guy I'd like to get those metrics in CS ;) So here you gave me way to criticaly upgrade my securiity :D again thanks dude :)

found part of the solution by putting the /etc/crowdsec/config.yaml file out of the container and changed the line acquisition_path to acquisition_dir and and create a folder in my mounted directory to put those acquisitions files instead of just having one file...

Hey I managed to get my phone blocked with multi testing wrong user and of course password \o/ So now that's done ! Extracting the configuration file and replace with no typo (I had a few so I had to precise) the path by a dir you can now put more than one file to the inquisition ;) And I just thought that I could just mount the file of my host to the CS pod so CS could do it's magic too for bad guys trying to ssh in even if the challange ssh key is stronger than password that does not mean you should put no security espacialy in those dark times ! xD So basicaly now the only thing is to do it now... yet for this one I think I should add a bouncer but how to give it access the system FW 🤔May be I will look at the bouncers and invest in a true FW it will not be lost xD 1 am here, need to sleep this over ;)
