2022-05-04 12:00:17 Adding static entries

Open the command prompt then use the ipconfig /all command to get the IP and MAC address Open / Comment

2022-05-04 12:00:17 *Note*: dynamic entries are added and deleted automatically when using TCP/IP sessions with remote computers.

Static entries are added manually and are deleted when the computer is restarted, and the network interface card restarted or other activities that affect it. Open / Comment

2022-05-04 12:00:17 Hacking Activity: Configure ARP entries in Windows

We are using Windows 7 for this exercise, but the commands should be able to work on other versions of windows as well.
Open the command prompt and enter the following command
arp –a
HERE,

aprcalls the ARP configure program located in Windows/System32 directory

-a is the parameter to display to contents of the ARP cache

You will get results similar to the following Open / Comment

2022-05-04 12:00:17 What is ARP Poisoning?

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.

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 Open / Comment
