The setup is fairly simple: make sure the GID matches a group that can read all your logs and set CUSTOM_HOSTNAME to something that identifies your server. opt/appdata/swag/log/nginx:/var/log/swag:ro opt/appdata/crowdsec/data:/var/lib/crowdsec/data:rw opt/appdata/crowdsec/config:/etc/crowdsec:rw COLLECTIONS=crowdsecurity/nginx crowdsecurity/http-cve crowdsecurity/whitelist-good-actors
Image: docker.io/crowdsecurity/crowdsec:latest The first thing we need is the Local API and Agent, which co-exist in the official container. The basic building blocks are the CrowdSec agent which parses your logs and detects malicious behaviour, one or more Bouncers which do the actual blocking, the Central API which is hosted by CrowdSec themselves and allows you to push and pull community blocks, and the Local API which acts as a central coordinator on your network for all the other parts. Unlike fail2ban, which uses a single service for detection and blocking of malicious traffic, CrowdSec is modular, allowing you to detect and block across multiple hosts and to easily integrate with different services.
FAIL2BAN PHPMYADMIN NGINX MOD
We recently published a docker mod to add the CrowdSec nginx bouncer to our swag and nginx containers so it seemed a good opportunity to take a quick look at how you can get started with it. Fail2ban obviously knows where to look (I had logpath = /var/log/auth.log but I removed it and still works).Īs soon as I enter a wrong pair of credentials, I can see it detected by fail2ban with this command: sudo tail -f /var/log/fail2ban.logīear in mind that if you change fail2ban configuration, you do not have to restart fail2ban.CrowdSec is a free, open-source and collaborative IPS it's like Fail2Ban but you share your bans with all of the other users to try and pre-emptively block malicious hosts. You will notice that I did not even mention a log file in the jail. ^%(_prefix_line)suser denied: (?:\S+|.*?) \(mysql-denied\) from \s*$Īlso your jail.local entry seems correct. You can see now why the filter is correct and will identify only the second case above. Whenever I try to login with a wrong username/password I get : Feb 13 23:42:42 hostname phpMyAdmin: user denied: sdasdas (mysql-denied) from
FAIL2BAN PHPMYADMIN NGINX PASSWORD
Whenever I try to login with a blank password I get : Feb 13 23:42:42 hostname phpMyAdmin: user denied: sdasdas (empty-denied) from
FAIL2BAN PHPMYADMIN NGINX MANUAL
So I am guessing that the manual is wrong in my case. and all my authentication errors go into /var/log/auth.log.
I did not modify the phpmyadmin config file in any way (default from installation). (no useful tip for enabling the phpyadmin logging) My /etc/fail2ban/jail.local file contains: Īnd the default /etc/fail2ban/filter.d/nf contains: # Fail2Ban fitler for the phpMyAdmin-syslogįailregex = ^%(_prefix_line)suser denied: (?:\S+|.*?) \(mysql-denied\) from \s*$ #chown www-data:www-data /var/log/phpmyadmin-auth.log and $cfg = '/var/log/phpmyadmin-auth.log' Īnd gave permissions to the log to www-data user using (note: unsure if this correct, pma is controluser) However, neither /var/log/auth.log, nor /var/log/syslog logged failed login attempts. Which should output failed login attempts to syslog or php according to docs In my /usr/share/phpmyadmin/ i have added: I have tried 3 methods to enable logging: Pma logging doesn't appear to work according to documentation. In any case, I am trying to setup the default nf filter for fail2ban to protect phpmyadmin. I installed phpmyadmin following this tutorial I can only guess that somehow ISPConfig may be interrupting something. I am on Debian 10.5 LAMP with ISPConfig, running PHPMYADMIN 4.9.0.1.
