Ethical Hacking ARP Poisoning And Softwares For ARP Poisoning Detection

ARP Poisonings :

ARP is the acronym for Address Resolution Protocol. It is used to convert IP address to physical addresses [MAC address] on a switch. The host sends an ARP broadcast on the network, and the recipient computer responds with its physical address [MAC Address]. The resolved IP/MAC address is then used to communicate. ARP poisoning is sending fake MAC addresses to the switch so that it can associate the fake MAC addresses with the IP address of a genuine computer on a network and hijack the traffic.

In this tutorial we will Learn -

• What is IP & Mac Address.

• What is Address Resolution Protocol (ARP) Poisoning?.

• Hacking Activity: Configure Static ARP in Windows.

• What is IP and MAC Addresses.

What is IP Address :

IP Address is the acronym for Internet Protocol address. An internet protocol address is used to uniquely identify a computer or device such as printers, storage disks on a computer network. There are currently two versions of IP addresses. IPv4 uses 32-bit numbers. Due to the massive growth of the internet, IPv6 has been developed, and it uses 128-bit numbers.

IPv4 addresses are formatted in four groups of numbers separated by dots. The minimum number is 0, and the maximum number is 255. An example of an IPv4 address looks like this;

IPv6 addresses are formatted in groups of six numbers separated by full colons. The group numbers are written as 4 hexadecimal digits. An example of an IPv6 address looks like this;

What is Mac Address :

MAC Address is the acronym for media access control address. MAC addresses are used to uniquely identify network interfaces for communication at the physical layer of the network. MAC addresses are usually embedded into the network card.

A MAC address is like a serial number of a phone while the IP address is like the phone number.

ARP Poisoning Countermeasures :

Static ARP entries : these can be defined in the local ARP cache and the switch configured to ignore all auto ARP reply packets. The disadvantage of this method is, it’s difficult to maintain on large networks. IP/MAC address mapping has to be distributed to all the computers on the network.

ARP poisoning detection software :

These systems can be used to cross check the IP/MAC address resolution and certify them if they are authenticated. Uncertified IP/MAC address resolutions can then be blocked.

Operating System Security : this measure is dependent on the operating system been used. The following are the basic techniques used by various operating systems.

Linux based : these work by ignoring unsolicited ARP reply packets.

Microsoft Windows : the ARP cache behavior can be configured via the registry. The following list includes some of the software that can be used to protect networks against sniffing;

AntiARP : provides protection against both passive and active sniffing

Agnitum Outpost Firewall : provides protection against passive sniffing

XArp : provides protection against both passive and active sniffing

Mac OS : ArpGuard can be used to provide protection. It protects against both active and passive sniffing.

Security for today and tomorrow

Maintaining data protection is one of the greatest challenges companies are facing today, because no one wants to risk a bad image due to media reports of data having been stolen from the company. Yet companies are still concentrating on protecting themselves from access from outside the company, although statistics have repeatedly shown that a large part of the spying is taking place from the local network. This is where a maximum of protection is needed that can be implemented with only a minimum of effort and without interrupting internal workflows.
Network Access Control (NAC) solutions support the company in this task. The ARP-GUARD solution, in particular, can be implemented easily and quickly because it requires no changes to existing network structures. It learns on its own which devices are on the network, and produces a graphic overview of the network including all existing switches and routers.

RELIABLE PROTECTION

Our security solution provides reliable protection against unauthorised access to the internal LAN and WLAN, as well as the Internet. With ARP-GUARD, only authorized devices are granted access to your network.

ARP-GUARD - the secure protection for your network

ARP-GUARD gives you complete access control for your network! New devices that are connected to the network are detected and reported in real-time. The devices are uniquely identified using the MAC address or certificates (802.1X). Additional fingerprints that are created when training the devices increase the security level.
ARP-GUARD thus makes protected and controlled access to the network possible. You decide how to deal with unauthorised devices with user-defined or company-specific rules found in access and security guidelines. These guidelines can range from notifying the administrator by email to automatic defence against unauthorised devices or relocating to special quarantine or guest VLANs.

The central network management system provides a comprehensive overview of all devices in your network. It detects every change in addresses or allocations and logs and displays these changes. Inventory lists of all of the devices located in the network are generated upon request and are always up-to-date. ARP-GUARD also supplies you with a history of the topography. With the help of this history you can identify when a specific device was in the network the last time and where was it connected, or which IP address was connected to what device at a specific time?
The reporting function of the ARP-GUARD also lets you show the logged incidents in a diagram. You can select between standardised and user-specific reports here. This lets you create analyses that help you to get an overview of events in your network - for example the number of unknown devices that want to access your network or the frequency of incidences on certain ports or switches.
To ensure that you don't lose your overview in large, complex networks, ARP-GUARD offers you a topology diagram. The network infrastructure is automatically detected by ARP-GUARD and shown in its form. The form and size of the topologies can be edited and modified any way you want.

There are numerous network connections and access points in the company that are either freely or easily accessible. Simple access to your company data - not just for employees! Security problems at the network infrastructure level can put the availability of the entire network at risk or allow an attacker to read or even manipulate the traffic of complete network segments. ARP-GUARD detects and locates internal attacks such as ARP poisoning, MAC flooding, IP spoofing, 'man-in-the-middle' attacks, etc. and defends itself independently.
Thanks to this protection, data can no longer be spied on, deleted or manipulated unnoticed. Secret product developments and internal company passwords are secure against unauthorised access. IP spoofing attacks are prevented to keep specific rights in the network from being obtained fraudulently.
By identifying address conflicts, ARP-GUARD makes a valuable contribution to quality assurance. It offers preventative protection against attacks that is easy to put into practice.

Controlled and secure access to IT networks

Virtually all internal company information can be accessed over your local network. Highly sensitive data vital to your company! Formulas, design plans, contracts, patents.
ARP-GUARD makes sure that users don't use any unauthorised notebooks, smartphones or even wireless access points. Our software solution protects your IT infrastructure from malware-infected external devices and your intellectual property from unauthorised access! Our security solution provides reliable protection against unauthorised access to the internal LAN and WLAN, as well as the Internet. With ARP-GUARD, only authorized devices are granted access to your network! Protection of your network takes place in real time, as does network monitoring, localization, and the identification and verification of newly connected devices.
Unambiguous identification of a device is a must. The MAC address or certificates (802.1X) are available here. The ISL proprietary fingerprint process also offers an identity check of the devices at the highest security level. You can combine these security mechanisms to define your own level of security. The unique and individually scalable sensor management architecture makes it possible to secure your company across sites no matter if you are a medium-sized company or a large corporation. ARP-GUARD functions independently of any vendor. You don't have to standardise or even replace your existing infrastructure. ARP-GUARD sees itself as a watchdog and observer of your network that enforces your centrally defined rules, i.e. your security policy, throughout the company.

The ARP-GUARD variants

ARP-GUARD's architecture is designed such that it can be used by small, medium-sized as well as large companies. Regardless of the company's size or what its need are, there is only one management level from which ARP-GUARD is centrally configured and operated. Depending on need, sensors can also be implemented for load balancing or for managing external areas.

Hardware Appliance

The long-standing partnership between SECUDOS and ISL has resulted in purpose-built appliances for ARP-GUARD - bundles comprising field-proven hardware from SECUDOS and the ARP-GUARD software from ISL. These appliances are shipped with ARP-GUARD software pre-installed which means they can be put into operation more quickly. No installation work (operating system, drivers, etc.) is required.

Virtual Appliance

The virtual ARP-GUARD appliance (AG-VIRT) was developed in collaboration with our technology partner, SECUDOS. The virtual appliance is based on the DOMOS4 operating system and is shipped with a pre-installed instance of ARP-GUARD. Commissioning takes place intuitively via a graphical user interface and takes about ten to fifteen minutes to complete.

ARP-GUARD Fingerprinting

The experts at ISL GmbH have already developed a fingerprinting tool for ARP-GUARD which searches for keys/certificates on end devices and downloads them to its database, where they are stored as reference values. Afterwards, when an end device is actively connected to the network, one of its public keys or certificates is fetched and compared with the reference value in the database. If the values differ, the device is removed from the network. In principle, fingerprinting, like 802.1X, is susceptible to session hijacking. The difference here, though, is that it's possible to check for compliance with other conditions (based on IP addresses, for example). For end devices with no cryptographic methods, simple fingerprints with specific device properties can provide a level of security far exceeding that offered by MAC address checking.
Fingerprinting is implemented in ARP-GUARD itself and has been activated in many corporate networks, including the networks of 80 Sparkassen (savings banks) in Germany for whom high levels of security is of paramount importance.
