## Key Features (v1.7.4)
|
|
- WAF capability with DropRequest helper for request blocking
|
|
- Refactored syslog acquisition using RestartableStreamer
|
|
- Optional pure-go SQLite driver for better compatibility
|
|
- Enhanced logging configuration with syslog media support
|
|
- Configurable usage metrics export (api.server.disable_usage_metrics_export)
|
|
- Fixed LAPI metrics cardinality issues with Prometheus
|
|
- Data race prevention in Docker acquisition
|
|
- Database query optimization for decision streams
|
|
- **Automatic OpenWrt log acquisition configuration**
|
|
- **UCI-based acquisition management**
|
|
|
|

## Installation
|
|
```bash
|
|
# From SecuBox build environment
|
|
cd /home/reepost/CyberMindStudio/_files/secubox-openwrt
|
|
make package/secubox/secubox-app-crowdsec/compile V=s
|
|
|
|
# Install on router
|
|
opkg install crowdsec_1.7.4-3_*.ipk
|
|
```
|
|
|
|
## Configuration
|
|
|
|
### UCI Configuration
|
|
CrowdSec uses UCI for configuration in `/etc/config/crowdsec`:
|
|
|
|
```bash
|
|
# View current configuration
|
|
uci show crowdsec
|
|
|
|
# Main settings
|
|
uci set crowdsec.crowdsec.data_dir='/srv/crowdsec/data'
|
|
uci set crowdsec.crowdsec.db_path='/srv/crowdsec/data/crowdsec.db'
|
|
|
|
# Acquisition settings
|
|
uci set crowdsec.acquisition.syslog_enabled='1'
|
|
uci set crowdsec.acquisition.firewall_enabled='1'
|
|
uci set crowdsec.acquisition.ssh_enabled='1'
|
|
uci set crowdsec.acquisition.http_enabled='0'
|
|
uci set crowdsec.acquisition.syslog_path='/var/log/messages'
|
|
|
|
# Hub settings
|
|
uci set crowdsec.hub.auto_install='1'
|
|
uci set crowdsec.hub.collections='crowdsecurity/linux crowdsecurity/iptables'
|
|
uci set crowdsec.hub.update_interval='7'
|
|
|
|
uci commit crowdsec
|
|
```
|
|
|
|
### File Locations
|
|
- Main config: `/etc/crowdsec/config.yaml`
|
|
- Acquisition directory: `/etc/crowdsec/acquis.d/`
|
|
- Legacy acquisition: `/etc/crowdsec/acquis.yaml`
|
|
- Profiles: `/etc/crowdsec/profiles.yaml`
|
|
- Local API: `/etc/crowdsec/local_api_credentials.yaml`
|
|
- Data directory: `/srv/crowdsec/data/`
|
|
|
|
## Log Acquisition Configuration
|
|
|
|
### Automatic Detection
|
|
On first boot, the defaults script automatically:
|
|
1. Detects OpenWrt log file configuration
|
|
2. Identifies installed services (Dropbear, firewall)
|
|
3. Generates appropriate acquisition configs
|
|
4. Installs recommended Hub collections
|
|
|
|
### Supported Log Sources
|
|
| Log Source | Default | Collection Required |
|
|
|------------|---------|---------------------|
|
|
| System Syslog | Enabled | crowdsecurity/linux |
|
|
| SSH/Dropbear | Enabled | crowdsecurity/linux |
|
|
| Firewall (iptables/nftables) | Enabled | crowdsecurity/iptables |
|
|
| HTTP (uHTTPd/nginx) | Disabled | crowdsecurity/http-cve |
|
|
|
|
### Custom Acquisition
|
|
Add custom acquisition configs to `/etc/crowdsec/acquis.d/`:
|
|
|
|
```yaml
|
|
# /etc/crowdsec/acquis.d/custom.yaml
|
|
filenames:
|
|
- /var/log/custom-app/*.log
|
|
labels:
|
|
type: syslog
|
|
```
|
|
|
|
### Syslog Service Mode
|
|
To run CrowdSec as a syslog server (receive logs from other devices):
|
|
|
|
```bash
|
|
uci set crowdsec.acquisition.syslog_listen_addr='0.0.0.0'
|
|
uci set crowdsec.acquisition.syslog_listen_port='514'
|
|
uci commit crowdsec
|
|
/etc/init.d/crowdsec restart
|
|
```
|
|
|
|
## Service Management
|
|
```bash
|
|
# Start CrowdSec
|
|
/etc/init.d/crowdsec start
|
|
|
|
# Stop CrowdSec
|
|
/etc/init.d/crowdsec stop
|
|
|
|
# Restart CrowdSec
|
|
/etc/init.d/crowdsec restart
|
|
|
|
# Check status
|
|
/etc/init.d/crowdsec status
|
|
```
|
|
|
|
## CLI Usage
|
|
CrowdSec CLI is available via `cscli`:
|
|
```bash
|
|
# Check version
|
|
cscli version
|
|
|
|
# Check acquisition status
|
|
cscli metrics show acquisition
|
|
|

|
|
```
|
|
|
|
## Hub Collections for OpenWrt
|
|
|
|
### Recommended Collections
|
|
```bash
|
|
# Core Linux detection (SSH brute-force, etc.)
|
|
cscli collections install crowdsecurity/linux
|
|
|
|
# Firewall log analysis (port scan detection)
|
|
cscli collections install crowdsecurity/iptables
|
|
|
|
# Syslog parsing
|
|
cscli parsers install crowdsecurity/syslog-logs
|
|
|
|
# Whitelists for reducing false positives
|
|
cscli parsers install crowdsecurity/whitelists
|
|
```
|
|
|
|
### Optional Collections
|
|
```bash
|
|
# HTTP attack detection
|
|
cscli collections install crowdsecurity/http-cve
|
|
|
|
# nginx logs
|
|
cscli collections install crowdsecurity/nginx
|
|
