We have talked about two different forms of cache poisoning attacks, DNS cache poisoning and ARP cache poisoning. Provide a brief description of what a cache poisoning attack is. In your answer be sure to include what benefit the attacker gains via a successful DNS and ARP cache poisoning and what attribute or feature of both the DNS and ARP protocol makes the susceptible to a cache position attack.

We have talked about two different forms of cache poisoning attacks, DNS cache poisoning and ARP cache poisoning. Provide a brief description of what a cache poisoning attack is. In your answer be sure to include what benefit the attacker gains via a successful DNS and ARP cache poisoning and what attribute or feature of both the DNS and ARP protocol makes the susceptible to a cache position attack.
Solution
A cache poisoning attack is a type of cyber attack where an attacker corrupts a DNS server's cache or an ARP cache by replacing a valid network address with one of their own. This allows the attacker to intercept or redirect data destined for a particular network address to their own system.
In a DNS cache poisoning attack, the attacker manipulates the process of domain name resolution, where domain names are converted into IP addresses. By corrupting the DNS server's cache, the attacker can redirect users to malicious websites even when they enter the correct domain name. This can be used for phishing attacks, spreading malware, or stealing sensitive information.
In an ARP cache poisoning attack, the attacker sends falsified ARP messages to a local area network. This links the attacker's MAC address with the IP address of a legitimate computer or server on the network. This allows the attacker to intercept data intended for that IP address, or even to impersonate the legitimate device.
The benefit the attacker gains from these attacks is the ability to intercept or redirect network traffic, which can be used for a variety of malicious purposes, such as stealing sensitive information or spreading malware.
The susceptibility of the DNS and ARP protocols to cache poisoning attacks lies in their trust-based nature. Both protocols assume that the responses they receive are legitimate, and do not have robust mechanisms for verifying this. This allows an attacker to easily insert their own malicious entries into the cache.

Question 1Smith, a professional hacker, initiated a network sniffing attack on the switched Ethernet environment of a target organization. He employed an automated tool to flood the switch with a fake physical address until the switch translation table became full. When the switch entered fail-open mode, it started acting as a hub by broadcasting packets. Now, Smith could easily accomplish his goal of network sniffing.Identify the type of attack performed by Smith in the above scenario. 1 pointARP spoofing DHCP starvation MAC flooding DNS poisoning 2.Question 2Which of the following tool helps an attacker perform an ARP poisoning attack? 1 pointWireshark High Orbit Ion Cannon BetterCAP Nbtstat
3What are two potential network problems that can result from ARP operation? (Choose two.)On large networks with low bandwidth, multiple ARP broadcasts could cause data communication delays.Multiple ARP replies result in the switch MAC address table containing entries that match the MAC addresses of hosts that are connected to the relevant switch port.Large numbers of ARP request broadcasts could cause the host MAC address table to overflow and prevent the host from communicating on the network.Network attackers could manipulate MAC address and IP address mappings in ARP messages with the intent of intercepting network traffic.Manually configuring static ARP associations could facilitate ARP poisoning or MAC address spoofing.
