# Option: logtarget
# Notes.: Set the log target. This could be a file, SYSLOG, STDERR or STDOUT.
# Only one log target can be specified.
# If you change logtarget from the default value and you are
# using logrotate -- also adjust or disable rotation in the
# corresponding configuration file
# (e.g. /etc/logrotate.d/fail2ban on Debian systems)
# Values: [ STDOUT | STDERR | SYSLOG | SYSOUT | FILE ] Default: STDERR
#
logtarget = /var/log/fail2ban.log
# Option: syslogsocket
# Notes: Set the syslog socket file. Only used when logtarget is SYSLOG
# auto uses platform.system() to determine predefined paths
# Values: [ auto | FILE ] Default: auto
syslogsocket = auto
# Option: socket
# Notes.: Set the socket file. This is used to communicate with the daemon. Do
# not remove this file when Fail2ban runs. It will not be possible to
# communicate with the server afterwards.

sudo service fail2ban statusNamesto tega spodnjega filtra za Dos napade rajši uporabite za Apache modul evasive lahko tudi modul security apache, ta filter vam bo blokiral tudi uporabnike, če niso njihovi IP Naslovi v fail2ban configuraciji odobreni oz. ignorirani. ODSVETUJEM UPORABO TEGA FILTRA.
Fail2Bam – GET/POST limit
Filter.d fail2ban http-dos.conf za GET – POST na mesto Napade npr. s tem primerom velja 300 zahtevkov v 300 sekundah ban oz. prepoved 1 uro vi si nastavite po svoje local.jail parametre filtra:
sudo nano /etc/fail2ban/filter.d/http-dos.confKopirajte v datoteko http-dos.conf spodnje direktive – shranite in zaženite ponovno fail2ban program:
[Definition]
failregex = ^<HOST> -.*"(GET|POST).*
ignoreregex =
sudo service fail2ban restart
sudo service fail2ban statusZa local.jail dodajte samo na koncu spodnjo direktivo – 300 ali get ali post ali kombinirano v 300 sekundah ban oz. prepoved za 1uro, dajte večje nastavitve npr. 600 – 600 – 24:
sudo nano /etc/fail2ban/jail.local [http-dos]
enabled = true
filter = http-dos
port = http,https
logpath = %(apache_access_log)s
maxretry = 300
findtime = 300
bantime = 1h
banaction = %(banaction_allports)sFail2Ban Apache-Custom.conf – Zaščita zoper XY povpraševanj (lastni filter) – Ta filter je napisan po lastnih logih strežnikov – Pozor blokira tudi 404 povpraševanja oz. odgovore.
Apache-Custom filter – osebno napisan filter za zaščito Apache (po osebnih log datotekah). POZOR!!! Ta filter vam bo blokiral tudi stranke oz. prijatelje, ki se povezujejo preko normalnih poti za prijavo. Zakomentirajte argumente, ki jih ne rabite oz. vam blokirajo dostop do spletnega mesta oz. prijavnega mesta!!! Primer pred vsako direktivo, ki jo ne rabite oz. vam blokira stranke ali uporabnike strežnika – DODAJ ZNAK: # TER ČISTO NA KONCU ZBRIŠITE IGNORE REGEX = te dve direktive (^<HOST> .* “GET /assets/.* in ^<HOST> .* “GET /img/.*)
Filter.d fail2ban apache-custom.conf – Napišite si za vaše spletne aplikacije lastne filtre oz. parametre:
sudo nano /etc/fail2ban/filter.d/apache-custom.confKopirajte v datoteko apache-custom.conf spodnje direktive – shranite in zaženite ponovno fail2ban program:

# The expresion log file for example:
# 101.33.59.9 - - [17/Jan/2020:14:10:41 +0000] "GET http://google.com/ HTTP/1.1" 400 3494 "-" "Mozilla"
# 101.33.59.9 - - [17/Jan/2020:14:10:44 +0000] "CONNECT yahoo.com:80" 400 3499 "-" "Mozilla"
#
# A regular expression such as the one up can match these easily down:
# (?i)^<HOST> -.*"(?:(?:GET|POST|HEAD) https?:|CONNECT [a-z0-9.-]+:[0-9]+)
#
# Bots scanning for Shellshock often send out requests like:
# 10.11.12.13 - - [17/Jan/2020:16:00:00 +0000] "GET /cgi-bin/printenv.cgi HTTP/1.0" 200 1 "-" "() { test;};echo \"Content-type: text/plain\"; echo; echo; /bin/rm -rf /var/www/"
# A regular expression like this will match the pattern for Shellshock:
# <HOST> -.*"\(\)\s*\{[^;"]+[^}"]+}\s*;

Malware Trail – Zaščita sistema zoper znanih napadalcev
Dodatek zaščita vašega strežnika preko MALTRAIL – Poberite in namestite App preko GitHub: https://github.com/stamparm/maltrail
Gremo zaščitit naš strežnik zoper znanih napadalcev in različnih SCAN – Skenirnih sistemov vašega omrežja. Ko ste namestili program zdaj ga skonfigurirajte tako, da bo vaš požarni zid blokiral takoj vse znane napadalce in XY omrežja, ki so na črni listi oz. “Slaba omrežja”.
Vse spodnje parametre si spremenite v vaš IP naslov strežnika in routerja oz. svičerja ali usmerjevalnika. Tukaj so predstavljene moje osebne nastavitve ne enem izmed strežnikov. Vi spremenite moj naslov strežnika IP 192.168.0.111 v vaš IP naslov in moj host strežnika piramidestudio spremenite v vaš host strežnika. Se prav za primer moj Router IP standard 192.168.0.1 – strežnik IP 192.168.0.111
