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.
What is the aim of an ARP spoofing attack chapter 5 exam?
ARP is a technique that is used to send fake ARP messages to other hosts in the LAN. The aim is to
associate IP addresses to the wrong MAC addresses
.
What is one way to mitigate ARP spoofing?
What is one way to mitigate ARP spoofing?
Layer 2 traceroute
.
What is a characteristic of port based memory buffering *?
All frames are stored in a common memory buffer. Frames are buffered in queues linked to specific ports
. All ports on a switch share a single memory buffer. Frames in the memory buffer are dynamically linked to destination ports.
What is the aim of ARP spoofing?
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.
What is the goal of ARP poisoning?
ARP Poisoning is a type of cyberattack that abuses weaknesses in the widely used Address Resolution Protocol (ARP)
to disrupt, redirect, or spy on network traffic
.
How can spoofing be prevented?
The options to protect against IP spoofing include
monitoring networks for atypical activity
, deploying packet filtering to detect inconsistencies (like outgoing packets with source IP addresses that don’t match those on the organization’s network), using robust verification methods (even among networked computers), …
Why would an attacker want to spoof a MAC address?
MAC spoofing bypasses access control measures,
gives a hacker the identity of a valid user, fools simple authentication checks, and can hide a rogue device on a network
. MAC spoofing operates within the network because routers rely on IP addresses to identify endpoints.
What does spoofing a MAC address do?
MAC spoofing is a technique for changing a factory-assigned Media Access Control (MAC) address of a network interface on a networked device. The MAC address that is hard-coded on a network interface controller (NIC) cannot be changed. … Essentially, MAC spoofing
entails changing a computer’s identity, for any reason
.
What are the two sizes minimum and maximum of an Ethernet frame?
Ethernet Frame Fields (7.1. 4) The
minimum Ethernet frame size is 64 bytes, and the expected maximum is 1518 bytes
. The frame size might be larger than that if additional requirements are included, such as VLAN tagging.
What is port based memory in networking?
Port-based memory. In port-based memory buffering,
frames are stored in queues that are linked to specific incoming and outgoing ports
. Shared memory. Shared memory buffering deposits all frames into a common memory buffer, which all the ports on the switch share.
How do switch buffers affect network performance?
They
provide error checking on the data received
. They store frames received, thus preventing premature frame discarding when network congestion occurs. They provide extra memory for a particular port if autonegotiation of speed or duplex fails.
How does ARP spoofing works?
ARP spoofing is a type of attack in which a malicious actor sends falsified ARP
(Address Resolution Protocol) messages over a local area network
. This results in the linking of an attacker’s MAC address with the IP address of a legitimate computer or server on the network.
How is spoofing done?
Spoofing is
the act of disguising a communication from an unknown source as being from a known, trusted source
. Spoofing can apply to emails, phone calls, and websites, or can be more technical, such as a computer spoofing an IP address, Address Resolution Protocol (ARP), or Domain Name System (DNS) server.
How does ARP work?
ARP
broadcasts a request packet to all the machines on the LAN
and asks if any of the machines are using that particular IP address. When a machine recognizes the IP address as its own, it sends a reply so ARP can update the cache for future reference and proceed with the communication.
What is ARP poisoning in cyber security?
ARP Poisoning (also known as ARP Spoofing) is
a type of cyber attack carried out over a Local Area Network (LAN) that involves sending malicious ARP packets to a default gateway on a LAN in order to change the pairings in its IP to MAC
address table. ARP Protocol translates IP addresses into MAC addresses.
