# Fail2ban configuration file
|
||||
#
|
||||
# Action to report IP address to abuseipdb.com
|
||||
# You must sign up to obtain an API key from abuseipdb.com.
|
||||
#
|
||||
# NOTE: These reports may include sensitive Info.
|
||||
# If you want cleaner reports that ensure no user data see the helper script at the below website.
|
||||
#
|
||||
# IMPORTANT:
|
||||
#
|
||||
# Reporting an IP of abuse is a serious complaint. Make sure that it is
|
||||
# serious. Fail2ban developers and network owners recommend you only use this
|
||||
# action for:
|
||||
# * The recidive where the IP has been banned multiple times
|
||||
# * Where maxretry has been set quite high, beyond the normal user typing
|
||||
# password incorrectly.
|
||||
# * For filters that have a low likelihood of receiving human errors
|
||||
#
|
||||
# This action relies on a api_key being added to the above action conf,
|
||||
# and the appropriate categories set.
|
||||
#
|
||||
# Example, for ssh bruteforce (in section [sshd] of `jail.local`):
|
||||
# action = %(known/action)s
|
||||
# abuseipdb[abuseipdb_apikey="my-api-key", abuseipdb_category="18,22"]
|
||||
#
|
||||
# See below for categories.
|
||||
#
|
||||
# Added to fail2ban by Andrew James Collett (ajcollett)
|
||||
|
||||
## abuseIPDB Categories, `the abuseipdb_category` MUST be set in the jail.conf action call.
|
||||
# Example, for ssh bruteforce: action = %(action_abuseipdb)s[abuseipdb_category="18,22"]
|
||||
# ID Title Description

# 4 DDoS Attack

# www.blocklist.de is a free and voluntary service provided by a

# Mail-Login-, FTP-, Webserver- and other services.
|

# The mission is to report all attacks to the abuse departments of the

# the customer about the infection and disable them
|

# IMPORTANT:

|

# Reporting an IP of abuse is a serious complaint. Make sure that it is

# Fail2Ban configuration file

# Author: Russell Odom <russ@gloomytrousers.co.uk>
|

# Submits attack reports to DShield (http://www.dshield.org/)
|
||||
#
|
||||
# You MUST configure at least:
|
||||
# <port> (the port that's being attacked - use number not name).
|
||||
#
|
||||
# You SHOULD also provide:
|
||||
# <myip> (your public IP address, if it's not the address of eth0)
|
||||
# <userid> (your DShield userID, if you have one - recommended, but reports will
|
||||
# be used anonymously if not)
|
||||
# <protocol> (the protocol in use - defaults to tcp)
|
||||
#
|
||||
# Best practice is to provide <port> and <protocol> in jail.conf like this:
|
||||
# action = dshield[port=1234,protocol=tcp]
|
||||
#
|
||||
# ...and create "dshield.local" with contents something like this:
|
||||
# [Init]
|
||||
# myip = 10.0.0.1
|
||||
# userid = 12345
|
||||
#
|
||||
# Other useful configuration values are <mailargs> (you can use for specifying
|
||||
# a different sender address for the report e-mails, which should match what is
|
||||
# configured at DShield), and <lines>/<minreportinterval>/<maxbufferage> (to
|
||||
# configure how often the buffer is flushed).

# Fail2ban Citrix Netscaler Action
|
||||
# by Juliano Jeziorny
|
||||
# juliano@jeziorny.eu
|
||||
#
|
||||
# The script will add offender IPs to a dataset on netscaler, the dataset can then be used to block the IPs at a cs/vserver or global level
|
||||
# This dataset is then used to block IPs using responder policies on the netscaler.
|
||||
#
|
||||
# The script assumes using HTTPS with unsecure certificate to access the netscaler,
|
||||
# if you have a valid certificate installed remove the -k from the curl lines, or if you want http change it accordingly (and remove the -k)
|
||||
#
|
||||
# This action depends on curl
|
||||
#
|
||||
# You need to populate the 3 options inside Init
|
||||
#
|
||||
# ns_host: IP or hostname of netslcaer appliance
|
||||
# ns_auth: username:password, suggest base64 encoded for a little added security (echo -n "username:password" | base64)
|
||||
# ns_dataset: Name of the netscaler dataset holding the IPs to be blocked.
|
||||
#
|
||||
# For further details on how to use it please check http://blog.ckzone.eu/2017/01/fail2ban-action-for-citrix-netscaler.html

# Fail2Ban configuration file for black-listing via nginx
|
||||
#
|

# Author: Serg G. Brester (aka sebres)
|
||||
#
|
||||
# To use 'nginx-block-map' action you should define some special blocks in your nginx configuration,
|
||||
# and use it hereafter in your locations (to notify fail2ban by failure, resp. nginx by ban).
|
||||
#
|
||||
# Example (argument "token_id" resp. cookie "session_id" used here as unique identifier for user):
|
||||
#
|
||||
# http {
|
||||
# ...
|
||||
# # maps to check user is blacklisted (banned in f2b):
|
||||
# #map $arg_token_id $blck_lst_tok { include blacklisted-tokens.map; }
|
||||
# map $cookie_session_id $blck_lst_ses { include blacklisted-sessions.map; }
|
||||
# ...
|
||||
# # special log-format to notify fail2ban about failures:
|
||||
# log_format f2b_session_errors '$msec failure "$cookie_session_id" - $remote_addr - $remote_user '
|
||||
# ;# '"$request" $status $bytes_sent '
|
||||
# # '"$http_referer" "$http_user_agent"';
|
||||
#
|
||||
# # location checking blacklisted values:
|
||||
# location ... {
|
||||
# # check banned sessionid:
|
||||
# if ($blck_lst_ses != "") {
|
||||
# try_files "" @f2b-banned;
|
||||
# }
|
||||
# ...
|
||||
# # notify fail2ban about a failure inside nginx:
|
||||
# error_page 401 = @notify-f2b;
|
||||
# ...
|
||||
# }
|
||||
# ...
|
||||
# # location for return with "403 Forbidden" if banned:
|
||||
# location @f2b-banned {
|
||||
# default_type text/html;
|
||||
# return 403 "<br/><center>
|
||||
# <b style=\"color:red; font-size:18pt; border:2pt solid black; padding:5pt;\">
|
||||
# You are banned!</b></center>";
|
||||
# }
|
||||
# ...
|
||||
# # location to notify fail2ban about a failure inside nginx:
|
||||
# location @notify-f2b {
|
||||
# access_log /var/log/nginx/f2b-auth-errors.log f2b_session_errors;
|
||||
# }
|
||||
# }
|
||||
# ...
|
||||
#
|
||||
# Note that quote-character (and possibly other special characters) are not allowed currently as session-id.
|
||||
# Thus please add any session-id validation rule in your locations (or in the corresponding backend-service),
|
||||
# like in example below:
|
||||
#
|
||||
# location ... {
|
||||
# if ($cookie_session_id !~ "^[\w\-]+$") {
|
||||
# return 403 "Wrong session-id"
|
||||
# }
|
||||
# ...
|
||||
# }
|
||||
#
|
||||

# This is for blocking whole hosts through blackhole routes.

|

# PRO:
|

# - Works on all kernel versions and as no compatibility problems (back to debian lenny and WAY further).
|
||||
# - It's FAST for very large numbers of blocked ips.
|
||||
# - It's FAST because it Blocks traffic before it enters common iptables chains used for filtering.
|
||||
# - It's per host, ideal as action against ssh password bruteforcing to block further attack attempts.
|

# - No additional software required beside iproute/iproute2

# Author: Eduardo Diaz

#
|

# This is for ipset protocol 6 (and hopefully later) (ipset v6.14).
|
||||
# for shorewall
|
||||
#
|
||||
# Use this setting in jail.conf to modify use this action instead of a
|
||||
# default one
|
||||
#
|
||||
# banaction = shorewall-ipset-proto6
|
||||
#
|
||||
# This requires the program ipset which is normally in package called ipset.
|
||||
#
|
||||
# IPset was a feature introduced in the linux kernel 2.6.39 and 3.0.0
|
||||
# kernels, and you need Shorewall >= 4.5.5 to use this action.
|
||||
#
|
||||
# The default Shorewall configuration is with "BLACKLISTNEWONLY=Yes" (see
|
||||
# file /etc/shorewall/shorewall.conf). This means that when Fail2ban adds a
|
||||
# new shorewall rule to ban an IP address, that rule will affect only new
|
||||
# connections. So if the attacker goes on trying using the same connection
|
||||
# he could even log in. In order to get the same behavior of the iptable
|
||||
# action (so that the ban is immediate) the /etc/shorewall/shorewall.conf
|
||||
# file should me modified with "BLACKLISTNEWONLY=No".
|
||||
#
|
||||
#
|
||||
# Enable shorewall to use a blacklist using iptables creating a file
|
||||
# /etc/shorewall/blrules and adding "DROP net:+f2b-ssh all" and
|
||||
# similar lines for every jail. To enable restoring you ipset you
|
||||
# must set SAVE_IPSETS=Yes in shorewall.conf . You can read more
|
||||
# about ipsets handling in Shorewall at http://shorewall.net/ipsets.html
|
||||
#
|
||||
# To force creation of the ipset in the case that somebody deletes the
|
||||
# ipset create a file /etc/shorewall/initdone and add one line for
|
||||
# every ipset (this files are in Perl) and add 1 at the end of the file.
|
||||
# The example:
|
||||
# system("/usr/sbin/ipset -quiet -exist create f2b-ssh hash:ip timeout 600 ");
|
||||
# 1;
|
||||
#
|
||||
# To destroy the ipset in shorewall you must add to the file /etc/shorewall/stopped
|
||||
# # One line of every ipset
|
||||
# system("/usr/sbin/ipset -quiet destroy f2b-ssh ");
|

# Fail2Ban action for sending xarf Login-Attack messages to IP owner
|

#
|
||||
# IMPORTANT:
|
||||
#
|
||||
# Emailing a IP owner of abuse is a serious complain. Make sure that it is
|
||||
# serious. Fail2ban developers and network owners recommend you only use this
|
||||
# action for:
|
||||
# * The recidive where the IP has been banned multiple times
|
||||
# * Where maxretry has been set quite high, beyond the normal user typing
|
||||
# password incorrectly.
|
||||
# * For filters that have a low likelihood of receiving human errors
|
||||
#
|
||||
# DEPENDENCIES:
|
||||
#
|
||||
# This requires the dig command from bind-utils
|
||||
#
|

# This uses the https://abusix.com/contactdb.html to lookup abuse contacts.
|

# XARF is a specification for sending a formatted response

# Login-Attack, Malware-Attack, Fraud (Phishing, etc.), Info DNSBL
