PING of Death Attack or DDoS  What is it? + Tips ▷ 2020

Computer security problems are still one of the biggest concerns for most users, and is that today you can find a large number of attacks that can cause different types of damage, one of them is the PING attack of death or also known as DDoS.

This term is known as the denial of service to the unavailability of a service. Therefore, reference is made to a a kind of blockage that is caused by a series of collateral effects of an overload of components in the IT infrastructure. This means that this problem originates when there is a external intentional cause that causes it.

All this allows the attacker to make network devices, operating systems, and servers are not able to respond to regular requests or do so with a delay. This will cause the computers to malfunction. In accordance with all this, here we are going to explain a little more about this type of DDoS attackTo do this, follow in detail everything that we will teach you below.

What is a PING of Death or DDoS attack and how does it work?

What is a PING of Death or DDoS attack and how does it work?

All of this is known as distributed denial of service (DDoS), or distributed denial in Spanish. This time the criminals aims cause delays in the responses of computers, for this they do not attack from a only team, but they must overload targeted systems with simultaneous patterns from multiple computers.

In this way, you can get to conform giant botnets with the aim of being able to cause all the necessary pauses so that the system is not able to generate a response to what they are requesting. Keep in mind that with such a network, a large amount of traffic that surpasses that which can be generated with a DoS attack, which starts from a single machine.

Agree with this, DDoS attacks offer drastic consequences for systems that have been affected and that generally, this have very little chance to identify the real source of the attack. This is all because attackers must operate on special Internet software agents Y without the consent of the operators, what allows them create the huge botnets.

Equipment that does not have a correct protection system that allows them to be centrally control. Therefore, it can be said that DDoS attacks are intended to flood servers with so many requests that it collapses and does not have the ability to respond. This allows effective than server can not comply so you can not offer your services correctly.

In order to understand a little better this type of problem originated in the internet servers it is very important to be able to differentiate these two attacks. For this you should consider this example based on the real life. The clearest example for this is a large store that has enough staff to serve the entire public, but they decide open a new offer on one of your products.

In this case they have made the decision to promote PS4 console for which they grant a large amount of free form. This has caused a large number of clients want to obtain the service for which their resources have collapsed, this may result in the store having to close its doors temporarily and thus prevent customers from accessing its services.

But, there is a customer who is much more cunning and makes the decision to attack the store with many more customers and installs a chip so that the thousands of customers turn into zombies. This means that all these clients will be controlled by an intruder, this will make the store’s resources are increasingly depleted and it may not have the ability to generate a positive response to the public. The same thing happens with DDoS attacks or also known as the distributed denial of a service.

The purpose of Attacker is saturating requests to the server, making it not have the capacity to respond to all of them until there comes a time where all requests are denied. While in the case of DoS attack, this is carried out using a alone Internet connection, so it is based on taking advantage software vulnerabilities or flooding the attacked machine with bogus requests, thus causing an overload of resources on the network.

Thus, the DDoS attack is carried out from several computers, while the DoS is manufactured from a single piece of equipment. That is why most owners who run DDoS attacks they have no idea that they are part of these attacks, and this is thanks to Trojans, malware and bots that infect each of these devices and are responsible for manufacturing each of the attacks without the authorization or approval of their operator.

What are the most obvious symptoms of a DDoS attack? How to identify them?

What are the most obvious symptoms of a DDoS attack?  How to identify them?

Knowing what they are DDoS attacks, the following will explain which are the most obvious symptoms that will allow you to know if you are being affected by one of them or not. In order to determine this, witness several highly visible aspects that will let you know if you are a victim or not of these internet attacks.

That is why here we show you what each of these symptoms are:

You start to witness excessive page latency

The most common way to determine if you are being victim Whether or not one of these attacks is if you start to witness excessive latency of web pages. If this is so, it may mean that end-user browsers and servers respond very slowly, so the answers take much longer to arrive.

If this occurs the chances of being under the presence of one of these DDoS attacks are very broad. Therefore, this may be the main reason why a page malfunction.

Monitor traffic

Another form of power detecting these security problems is by monitoring web traffic. For this you can have a record of all traffic and how it acts. This allows detect if there is any problem or unusual entry of traffic that may be indicating that there is a possible DDoS problem.

You can too monitor the impact period and the frequency with which it is repeated within a certain time. All this will help you to know whether or not you are being a victim of these security problems on web servers.

Suspicious users

If by chance you have noticed that there is a user who has been sending requests from time to time in the last 24 hours, then it may be one of these attackers. This means that you may be suffering from one of these attacks even though in the computer is not showing you a malfunction yet.

Wait time

You can also be checking the waiting time for any kind of behavior you see suspicious, specially in unknown traffic to your server or device. In this way, you can start check traffic loads, wait time to service and amount of CPU usage, Each of these aspects can give you an indication if you are being attacked or not.

Tips to prevent a DDoS attack and keep your network safe

Tips to prevent a DDoS attack and keep your network safe

Bearing in mind all the problems that can lead to cause these attacks, here we are going to show you the different measurements of security that have been established so that they can be counteract each of these overloads produced by DDoS attacks.

For this, it is essential to be able identify critical IP addresses, as well as all the vulnerabilities of the system since this will be the entrance of the attackers. Therefore, before I start giving you the main protection measures in these cases, It is essential that you bear in mind that you must have minimum hardware and software resources that they allow you block these attacks.

Therefore, follow each of these recommendations:

Blocked IP list

The first thing to keep in mind are the black lists that allow the identification of the critical IP addresses and the discarding of packets. This type of security measures can be carried out either in a manual or automatic through the list of blocking firewalls.

The filters

It is also possible that they are defined limits on the amounts of data processed simultaneously to filter out all kinds of abnormal packets. Here you should keep in mind that not all the time proxies allow many clients to connect from the same server IP address, so you could get to generate crashes without any reason. Although it is important to be better safe than sorry in these types of cases.

Load balancing

This is considered one of the most effective measures against overload in load distribution of different systems. In these cases the use of load balancers allow services to be extended to multiple physical machines. Therefore, in this way the user will be able to control these DoS and DDoS attacks only up to a certain point. Without successfully controlling this attack, it can be neutralized.

SYN cookies

Considered as another of the more optimal security measures for these cases, here the information on SYN packets are no longer stored on the server, but are now shipped as cookies encrypted to the client. This allows attacks from SYN flood can reach compromise the computer but in this case the system memory will not be affected.
