What is ARP spoofing and how does it work?

An ARP spoofing, also known as ARP poisoning, is a Man in the Middle (MitM) attack that allows attackers to intercept communication between network devices. The two devices update their ARP cache entries and from that point onwards, communicate with the attacker instead of directly with each other.

What is spoofing and how can it be used in an attack?

Spoofing is when an attacker impersonates an authorized device or user to steal data, spread malware, or bypass access control systems. There are many different types of spoofing, with three of the most common being: IP address spoofing – Attacker sends packets over the network from a false IP address.

What is the aim of an ARP spoofing attack?

Explanation:In an ARP spoofing attack, a malicious host intercepts ARP requests and replies to them so that network hosts will map an IP address to the MAC address of the malicious host.

Why would you want to spoof your MAC address?

Motivation. Changing the assigned MAC address may allow the user to bypass access control lists on servers or routers, either hiding a computer on a network or allowing it to impersonate another network device. MAC spoofing is done for legitimate and illicit purposes alike.

What is the best defense to use against ARP spoofing?

ARP spoofing Detection & Prevention Authentication & Data Encoding. Authenticating a data sender’s identity in some way can prevent receiving data from a malicious user. Packet filters. Packet filters are like inspectors which sit and carefully examine all the packets being transmitted across the network. Using Static ARP. Using VPNs. Use Anti-ARP Tools.

Is there a defense against ARP spoofing?

Using VPNs (Virtual Private Networks) is one of the best ways to get protection against ARP spoofing attack (here are some best VPNs). A Virtual Private Network uses an encrypted tunnel for not…

What is ARP poisoning and how does it work?

In computer networking, ARP spoofing, ARP cache poisoning, or ARP poison routing, is a technique by which an attacker sends (spoofed) Address Resolution Protocol (ARP) messages onto a local area network.

How to prevent ARP poisoning?

Static ARP entries. This solution involves a lot of administrative overhead and is only recommended for smaller networks.

Encryption. Protocols such as HTTPS and SSH can also help to reduce the chances of a successful ARP poisoning attack.

VPNs.

Packet filters.
