 # Crowdsec Bouncer Traefik plugin
 
+> New! This plugin now supports [AppSec](https://doc.crowdsec.net/docs/next/appsec/intro/) feature including virtual patching and capabilities support for your legacy ModSecurity rules.
+
 This plugin aims to implement a Crowdsec Bouncer in a Traefik plugin.
 
 > [CrowdSec](https://www.crowdsec.net/) is an open-source and collaborative IPS (Intrusion Prevention System) and a security suite.

 When used with Crowdsec it will leverage the local API which will analyze Traefik logs and take decisions on the requests made by users/bots. Malicious actors will be banned based on patterns used against your website.
 
-There are 4 operating modes (CrowdsecMode) for this plugin:
+Appsec feature is supported from plugin version 1.2.0 and Crowdsec 1.6.0.
+
+The AppSec Component offers:
+
+- Low-effort virtual patching capabilities.
+- Support for your legacy ModSecurity rules.
+- Combining classic WAF benefits with advanced CrowdSec features for otherwise difficult advanced behavior detection.
+More information on appsec in the [Crowdsec Documentation](https://doc.crowdsec.net/docs/next/appsec/intro/).
+
+Remediation offered by [Crowdsec](https://docs.crowdsec.net/u/bouncers/intro) and supported by the plugin can be either `ban` or `captcha`.  
+For the `ban` remediation the user will be blocked in Traefik (HTTP 403).  
+For the `captcha` remediation, the user will be redirected to a page to complete a captcha challenge.  
+
+On successfull completion, he will be cleaned for a specified period of time before a new resolution challenge is expected if Crowdsec still has a decision to verify the user behavior. See the example captcha for more informations and configuration intructions.  
+The following captcha providers are supported now:
+ - [hcaptcha](https://www.hcaptcha.com/)
+ - [recaptcha](https://www.google.com/recaptcha/about/)
+ - [turnstile](https://www.cloudflare.com/fr-fr/products/turnstile/)
+
+
+There are 5 operating modes (CrowdsecMode) for this plugin:
 
 | Mode | Description |
 |------|------|
 | none | If the client IP is on ban list, it will get a http code 403 response. Otherwise, request will continue as usual. All request call the Crowdsec LAPI |
-| live | If the client IP is on ban list, it will get a http code 403 response. Otherwise, request will continue as usual.    The bouncer can leverage use of a local cache in order to reduce the number of requests made to the Crowdsec LAPI. It will keep in cache the status for  each IP that makes queries. |

 | stream | Stream Streaming mode allows you to keep in the local cache only the Banned IPs, every requests that does not hit the cache is authorized. Every minute, the cache is updated with news from the Crowdsec LAPI. |
-| alone | Standalone mode, similar to the streaming mode but the blacklisted IPs are fetched on the CAPI. Every 2 hours, the cache is updated with news from the Crowdsec CAPI. It does not include any localy banned IP, but can work without a crowdsec service. |

+| appsec | Disable Crowdsec IP checking but apply Crowdsec Appsec checking. This mode is intended to be used when Crowdsec IP checking is applied at the Firewall Level. |
 
 The `streaming mode` is recommended for performance, decisions are updated every 60 sec by default and that's the only communication between Traefik and Crowdsec. Every request that happens hits the cache for quick decisions.
 
 The cache can be local to Traefik using the filesystem, or a separate Redis instance.  
-Support for Redis is currently in beta (requires version 7.0.X of Redis).

+# Example
+## Enabling AppSec WAF feature from crowdsec
+
+You mostly need to configure Crowdsec for this to work by enabling virtual patching and configuring some custom rules.
+In the example we use a whoami container protected by crowdsec with virtual patching enabled.
+
+The Traefik instance just needs to know where appsec engine is located
+```yaml
+  labels:
+      
+      - "traefik.http.middlewares.crowdsec-bar.plugin.bouncer.crowdsecappsecenabled=true"
+      - "traefik.http.middlewares.crowdsec-bar.plugin.bouncer.crowdsecappsechost=crowdsec:7422"
+```
+We can try to query normally the whoami server:
+```bash
+curl http://localhost:8000/foo
+```
+
+And then we verify that a malicious request will be blocked: 
+```bash
+curl http://localhost:8000/foo/rpc2
+```
+You should get a 403 on http://localhost:8000/foo/rpc2
+
+To play the demo environment run:
+```bash
+make run_appsec
+```

+# Example
+## Enabling catpcha response from crowdsec
+
+Crowdsec support 3 remediations solutions `ban`, `captcha`, and `throttle`.  
+This plugins support the `ban` and `captcha` remediation.  
+
+### Traefik configuration
+
+The minimal configuration is defined below.  
+For now 3 captcha providers are supported:  
+ - [hcaptcha](https://www.hcaptcha.com/)
+ - [recaptcha](https://www.google.com/recaptcha/about/)
+ - [turnstile](https://www.cloudflare.com/fr-fr/products/turnstile/)
+
+```yaml
+  labels:
+      # Choose captcha provider
+      - "traefik.http.middlewares.crowdsec.plugin.bouncer.captchaProvider=hcaptcha"
+      # Define captcha site key
+      - "traefik.http.middlewares.crowdsec.plugin.bouncer.captchaSiteKey=FIXME"
+      # Define captcha secret key
+      - "traefik.http.middlewares.crowdsec.plugin.bouncer.captchaSecretKey=FIXME"
+      # Define captcha grade period seconds
+      - "traefik.http.middlewares.crowdsec.plugin.bouncer.captchaGracePeriodSeconds=1800"
+      # Define captcha HTML file path
+      - "traefik.http.middlewares.crowdsec.plugin.bouncer.captchaHTMLFilePath=/captcha.html"
+```
+
+The captcha HTML file must be present in the Traefik container (bind mounted or added during a custom build).  
+It is not directly accessible from Traefik even when importing the plugin, so [download](https://raw.githubusercontent.com/maxlerebourg/crowdsec-bouncer-traefik-plugin/master/captcha.html) it locally to expose it to Traefik.
+
+```yaml 
+  ...
+  traefik:
+    image: "traefik:v3.0.0"
+    volumes:
+      - './captcha.html:/captcha.html'
+  ...
+```
+### Crowdsec configuration
+
+Crowdsec by default will take the ban action on suspicious activity detected in logs.  
+To instruct Crowdsec to use captcha remediation, change the `/etc/crowdsec/profiles.yaml`.   
+
+2 modes are supported:
+- Always return a captcha decision
+- Return a captcha decision the first X times and then a ban decision.
+
+The second mode could be used to prevent repeated malicious activity.
+More information is available on configuring Crowdsec in the [official documentation](https://docs.crowdsec.net/docs/next/profiles/captcha_profile/).
+
+```yaml
+  ...
+  crowdsec:
+    image: crowdsecurity/crowdsec:v1.6.1-2
+    volumes:
+      # For captcha and ban mixed decision
+      - './profiles.yaml:/etc/crowdsec/profiles.yaml:ro' 
+      # For captcha only remediation
+      # - './profiles_captcha_only.yaml:/etc/crowdsec/profiles.yaml:ro'
+  ...
+```
+## Exemple navigation
+We can try to query normally the whoami server:
+```bash
+curl http://localhost:8000/foo
+```
+
+We can try to ban ourself
+
+```bash
+docker exec crowdsec cscli decisions add --ip 10.0.0.20 -d 4h --type captcha
+```
+
+![image decision captcha](image_decision_captcha.png)
+
+We will see in the browser the captcha validation page:
+
+![image captcha validation](image_captcha_validation.png)
+
+To play the demo environment run:
+```bash
+make run_captcha
+```
+
+> Note, if we are banned with a "ban" decision from crowdsec a captcha will not be asked and you will have to wait for the decision to expire or remove it manually.  
+
+```bash
+docker exec crowdsec cscli decisions add --ip 10.0.0.10 -d 10m --type ban
+```

+# Example
+## Adding a custom ban page
+
+Traefik can return a custom HTML ban page along with the 403 HTTP response code.  
+This can be usefull as some browser (Firefox for instance) return a 403 blank webpage and we can mistake a server/reverse-proxy error with a ban from Crowdsec.  
+
+### Traefik configuration
+
+
+```yaml
+  labels:
+      # Define ban HTML file path
+      - "traefik.http.middlewares.crowdsec.plugin.bouncer.banHtmlFilePath=/ban.html"
+```
+
+The ban HTML file must be present in the Traefik container (bind mounted or added during a custom build).  
+It is not directly accessible from Traefik even when importing the plugin, so [download](https://raw.githubusercontent.com/maxlerebourg/crowdsec-bouncer-traefik-plugin/master/ban.html) it locally to expose it to Traefik.
+
+```yaml 
+  ...
+  traefik:
+    image: "traefik:v2.11.0"
+    volumes:
+      - './ban.html:/ban.html'
+  ...
+```
+
+## Exemple navigation
+
+We can try to query normally the whoami server:
+```bash
+curl http://localhost:8000/foo
+```
+
+We can try to ban ourself
+
+```bash
+docker exec crowdsec cscli decisions add --ip 10.0.0.20 -d 4h --type ban
+```
+![image decision ban](image_decision_ban.png)
+
+We will see in the browser the ban custom page:
+
+To play the demo environment run:
+```bash
+make run_custom_ban_page
+```
