# 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
# %(action_abuseipdb)s[abuseipdb_apikey="my-api-key", abuseipdb_category="18,22"]
#
# See below for catagories.
#
# Original Ref: https://wiki.shaunc.com/wikka.php?wakka=ReportingToAbuseIPDBWithFail2Ban
# Added to fail2ban by Andrew James Collett (ajcollett)
## abuseIPDB Catagories, `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
# 3 Fraud Orders
# 4 DDoS Attack
# 9 Open Proxy
# 10 Web Spam
# 11 Email Spam
# 14 Port Scan
# 18 Brute-Force
# 19 Bad Web Bot
# 20 Exploited Host
# 21 Web App Attack
# 22 SSH Secure Shell (SSH) abuse. Use this category in combination with more specific categories.

# Sends a complaint e-mail to addresses listed in the whois record for an
# offending IP address.
# This uses the https://abusix.com/contactdb.html to lookup abuse contacts.
#
# DEPENDENCIES:
# This requires the dig command from bind-utils
#
# You should provide the <logpath> in the jail config - lines from the log
# matching the given IP address will be provided in the complaint as evidence.
#
# WARNING
# -------
#
# Please do not use this action unless you are certain that fail2ban
# does not result in "false positives" for your deployment. False
# positive reports could serve a mis-favor to the original cause by
# flooding corresponding contact addresses, and complicating the work
# of administration personnel responsible for handling (verified) legit
# complains.
#
# Please consider using e.g. sendmail-whois-lines.conf action which
# would send the reports with relevant information to you, so the
# report could be first reviewed and then forwarded to a corresponding
# contact if legit.

# Fail2Ban configuration file

# 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).

# Because of the rich rule commands requires firewalld-0.3.1+
# This action uses firewalld rich-rules which gives you a cleaner iptables since it stores rules according to zones and not
# by chain. So for an example all deny rules will be listed under <zone>_deny and all log rules under <zone>_log.
#
# Also this action logs banned access attempts so you can filter that and increase ban time for offenders.
#
# If you use the --permanent rule you get a xml file in /etc/firewalld/zones/<zone>.xml that can be shared and parsed easliy
#
# Example commands to view rules:
# firewall-cmd [--zone=<zone>] --list-rich-rules
# firewall-cmd [--zone=<zone>] --list-all
# firewall-cmd [--zone=zone] --query-rich-rule='rule'

# Changing iptables rules requires root privileges. If fail2ban is

# a normal user, the configuration must be done by some other means
# (e.g. using static firewall configuration with the
# iptables-persistent package).
#
# Explanation of the rule below:
# Check if any packets coming from an IP on the <iptname>
# list have been seen in the last 3600 seconds. If yes, update the
# timestamp for this IP and drop the packet. If not, let the packet
# through.
#
# Fail2ban inserts blacklisted hosts into the <iptname> list
# and removes them from the list after some time, according to its
# own rules. The 3600 second timeout is independent and acts as a
# safeguard in case the fail2ban process dies unexpectedly. The

# 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"
# }
# ...
# }
#
# The parameters for jail corresponding log-format (f2b_session_errors):
#
# [nginx-blck-lst]
# filter =
# datepattern = ^Epoch
# failregex = ^ failure "<F-ID>[^"]+</F-ID>" - <ADDR>
# usedns = no
#
# The same log-file can be used for IP-related jail (additionally to session-related, to ban very bad IPs):
#
# [nginx-blck-ip]
# maxretry = 100
# filter =
# datepattern = ^Epoch
# failregex = ^ failure "[^"]+" - <ADDR>

# Author: Michael Gebetsroither
#
# 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
#
# CON:
# - Blocking is per IP and NOT per service, but ideal as action against ssh password bruteforcing hosts

# 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 ");
# 1; # This must go to the end of the file if not shorewall compilation fails

# 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
# for non-messaging based abuse including:
#
# Login-Attack, Malware-Attack, Fraud (Phishing, etc.), Info DNSBL
#
# For details see:
# https://github.com/xarf/xarf-specification

# HTTP_FORBIDDEN and not AUTH_GENERAL_ERROR or HTTP_INTERNAL_SERVER_ERROR.
#
# An unauthorized response 401 is the first step for a browser to instigate authentication
# however apache doesn't log this as an error. Only subsequent errors are logged in the
# error log.

# all of these expressions. Lots of submodules like mod_authz_* return back to mod_authz_core
# to return the actual failure.

# Fail2Ban filter for dropbear
#
# NOTE: The regex below is ONLY intended to work with a patched
# version of Dropbear as described here:
# http://www.unchartedbackwaters.co.uk/pyblosxom/static/patches
# ^%(__prefix_line)sexit before auth from <HOST>.*\s*$
#
# The standard Dropbear output doesn't provide enough information to
# ban all types of attack. The Dropbear patch adds IP address
# information to the 'exit before auth' message which is always
# produced for any form of non-successful login. It is that message
# which this file matches.
#
# More information: http://bugs.debian.org/546913

# Read common prefixes. If any customizations available -- read them from
# common.local
before = common.conf

# DEV Notes:
#
# The first two regexs here match the unmodified dropbear messages. It isn't
# possible to match the source of the 'exit before auth' messages from dropbear
# as they don't include the "from <HOST>" bit.
#
# The second last failregex line we need to match with the modified dropbear.
#
# For the second regex the following apply:
