DESCRIPTION
ArpON (ARP handler inspection) is a portable handler daemon that make ARP protocol secure in order to
avoid the Man In The Middle (MITM) attack through ARP Spoofing, ARP Cache Poisoning or ARP Poison Routing
(APR) attacks. It blocks also the derived attacks by it, which Sniffing, Hijacking, Injection, Filtering
& co attacks for more complex derived attacks, as: DNS Spoofing, WEB Spoofing, Session Hijacking and
SSL/TLS Hijacking & co attacks.
This is possible using three kinds of anti ARP Spoofing tecniques: the first is based on SARPI or "Static
ARP Inspection" in statically configured networks without DHCP; the second on DARPI or "Dynamic ARP
Inspection" in dynamically configured networks having DHCP; the third on HARPI or "Hybrid ARP Inspection"
in "hybrid" networks, that is in statically and dynamically (DHCP) configured networks together.
ArpON is therefore a proactive Point-to-Point, Point-to-Multipoint and Multipoint based solution that
requires a daemon in every host of the connection for authenticate each host through an authentication of
type cooperative between the hosts and that doesn't modify the classic ARP standard base protocol by
IETF, but rather sets precise policies by using SARPI for static networks, DARPI for dynamic networks and
HARPI for hybrid networks thus making today's standardized protocol working and secure from any foreign
intrusion.

OPTIONS
TASK MODE
-n (--nice) <Nice Value>
Sets PID's CPU priority (Default: 0 nice).
-p (--pid-file) <Pid file>
Sets the pid file (Default /var/run/arpon.pid).
-q (--quiet)
Works in background task.
LOG MODE
-f (--log-file) <Log file>
Sets the log file (Default: /var/log/arpon.log).
-g (--log)
Works in logging mode.
DEVICE MANAGER
ArpON is an ARP handler and it is able to handle network devices automatically (default) or manually, to
print a list of up network interfaces of the system.
It identifies the interface's datalink layer you are using but it supports only Ethernet/Wireless as
datalink. It sets the netowrk interface and check running, online ready and it deletes the PROMISCUE
flag. The online ready checks unplug (virtual and physical), boot, hibernation and suspension OS'
features for Ethernet/Wireless card. It handles these features and reset the network interface
automatically when it will ready.
-i (--iface) <Iface>
Sets your device manually.
-o (--iface-auto)
Sets device automatically.
-l (--iface-list)
Prints all supported devices.
STATIC ARP INSPECTION
SARPI detects and blocks Man In The Middle (MITM) attack through ARP Spoofing, ARP Cache Poisoning, ARP
Poison Routing (APR) attacks and it is countermeasure against these attacks and the derived attacks by
it, which Sniffing, Hijacking, Injection, Filtering & co attacks for more complex derived attacks, as:
DNS Spoofing, WEB Spoofing, Session Hijacking and SSL/TLS Hijacking & co attacks.
This solution is therefore a Point-to-Point, Point-to-Multipoint and Multipoint based solution that
requires a daemon in every host of the connection for authenticate each host through an authentication of
type cooperative between the hosts.
It manages a list with static entries, making it an optimal choice in those statically configured
networks without DHCP.
Finally, it's possible to use SARPI as a daemon, using the "TASK MODE" and "LOG MODE" feature of
ArpON. It supports daemon exit by SIGINT, SIGTERM, SIGQUIT and daemon reboot by SIGHUP and SIGCONT POSIX
signals.
-c (--sarpi-cache) <Cache file>
Sets SARPI entries from file (Default: /etc/arpon.sarpi).
-x (--sarpi-timeout) <Timeout>
Sets SARPI Cache refresh timeout (Default: 5 minuts).
-S (--sarpi)
Manages ARP Cache statically.
DYNAMIC ARP INSPECTION
DARPI detects and blocks Man In The Middle (MITM) attack through ARP Spoofing, ARP Cache Poisoning, ARP
Poison Routing (APR) attacks and it is countermeasure against these attacks and the derived attacks by
it, which Sniffing, Hijacking, Injection, Filtering & co attacks for more complex derived attacks, as:
DNS Spoofing, WEB Spoofing, Session Hijacking and SSL/TLS Hijacking & co attacks.
This solution is therefore a Point-to-Point, Point-to-Multipoint and Multipoint based solution that
requires a daemon in every host of the connection for authenticate each host through an authentication of
type cooperative between the hosts.
It manages uniquely a list with dynamic entries. Therefore it's an optimal solution in dynamically
configured networks having DHCP.
Finally, it's possible to use DARPI as a daemon, using the "TASK MODE" and "LOG MODE" feature of
ArpON. It supports daemon exit by SIGINT, SIGTERM, SIGQUIT and daemon reboot by SIGHUP and SIGCONT POSIX
signals.
-y (--darpi-timeout) <Timeout>
Sets DARPI entries response max timeout (Default: 5 seconds).
-D (--darpi)
Manages ARP Cache dynamically.
HYBRID ARP INSPECTION
HARPI detects and blocks Man In The Middle (MITM) attack through ARP Spoofing, ARP Cache Poisoning, ARP
Poison Routing (APR) attacks and it is countermeasure against these attacks and the derived attacks by
it, which Sniffing, Hijacking, Injection, Filtering & co attacks for more complex derived attacks, as:
DNS Spoofing, WEB Spoofing, Session Hijacking and SSL/TLS Hijacking & co attacks.
This solution is therefore a Point-to-Point, Point-to-Multipoint and Multipoint based solution that
requires a daemon in every host of the connection for authenticate each host through an authentication of
type cooperative between the hosts.
It manages two lists simultaneously: a list with static entries and a list with dynamic entries.
Therefore it's an optimal solution in statically and dynamically (DHCP) configured networks together.
Finally, it's possible to use DARPI as a daemon, using the "TASK MODE" and "LOG MODE" feature of
ArpON. It supports daemon exit by SIGINT, SIGTERM, SIGQUIT and daemon reboot by SIGHUP and SIGCONT POSIX
signals.
-c (--sarpi-cache) <Cache file>
Sets HARPI entries from file (Default: /etc/arpon.sarpi).
-x (--sarpi-timeout) <Timeout>
Sets HARPI Cache refresh timeout (Default: 5 minuts).
-y (--darpi-timeout) <Timeout>
Sets HARPI entries response max timeout (Default: 5 seconds).
-H (--harpi)
Manage ARP Cache statically and dynamically.
