#Which method would mitigate a mac address flooding attack Pc#This type of attack consists of fragmenting an ICMP packet, with the aim that the victim cannot reassemble it. This causes the victim’s CPU usage to increase, and has a major bottleneck. The result of this attack is usually that the victim’s PC becomes very slow, due to the CPU being too busy trying to reassemble the packet. #Which method would mitigate a mac address flooding attack series#This type of attack consists of sending a series of very large packets, with the aim that the target (the victim) is not able to assemble these packets, saturating the operating system and blocking it. It is possible that once the attack stops, it needs to be restarted so that it can function properly again. Today the kernels of operating systems incorporate protections against these attacks. #Which method would mitigate a mac address flooding attack how to#This attack is similar to the previous one, it consists of sending a packet of more than 65536 bytes, causing the operating system not to know how to handle this large packet, causing the operating system to crash when trying to assemble it again. Today this attack does not work, because the operating system will drop the packets directly. It is very important to know about this attack to avoid it in the future, but we already told you that this attack no longer works because operating systems incorporate a large number of protections to prevent it. This type of denial of service attack allows the victim’s bandwidth to be exhausted. It consists of sending a large amount of information using ICMP Echo Request packets, that is, the typical ping, but modified to be larger than usual. In addition, the victim could respond to you with ICMP Echo Reply packets (ping response), so we will have additional overhead, both on the network and on the victim. The most normal thing is to use one or several very powerful computers to attack the same victim, in this way, the victim will not be able to correctly manage the traffic generated. Some of the problems that we will find if we do a DoS attack is that we will notice a huge drop in network performance and a lot of slowness (opening files or accessing websites). A particular website is totally inaccessible and unavailable. We will be unable to enter any website that we attempt to access. Drastic increase in the amount of spam we receive. DNS zone transfer attack DoS attack or denial of service attackĪ denial-of-service attack, has as its objective disable the use of a system, an application, a computer or a server, in order to block the service for which it is intended. This attack can affect both the source that offers the information, such as an application or the transmission channel, as well as the computer network, or in other words, the cybercriminal will try to prevent users from accessing information or services. The most common type is when an attacker “floods” a network with a large amount of data, causing the entire network to be saturated. For example, in a DoS attack on a website, when we write a URL and access it, we will be sending a request to show us the information, in this case, an attacker could make millions of requests with the aim of collapsing the entire system. For this reason, this attack takes the name of «denial of service»,. ![]()
