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 Sniff‐
ing, 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 con‐
figured 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.
FEATURES
- Support for interfaces: Ethernet, Wireless

tion OS, Suspension OS
- Proactive based solution for connections: Point-to-Point, Point-to-
Multipoint, Multipoint
- Type of authentication for host: Cooperative between the hosts

Cluster with load-balancing, High-Availability (HA) Cluster
- Blocks the Man In The Middle (MITM) attack through: ARP Spoofing, ARP
Cache Poisoning, ARP Poison Routing (APR)
- Three kinds of anti ARP Spoofing tecniques: SARPI or Static ARP
Inspection, DARPI or Dynamic ARP Inspection, HARPI or Hybrid ARP
Inspection

& co attacks

sion Hijacking, SSL/TLS Hijacking & co attacks

cut, Metasploit, arpspoof, sslsniff, sslstrip & co tools
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 auto‐
matically (default) or manually, to print a list of up network inter‐
faces of the system.
It identifies the interface's datalink layer you are using but it sup‐
ports 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 stati‐
cally 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.
