HACK & HACKER

Distributed Network Attacks are commonly known as Distributed Denial of Service (DDoS) attacks. These types of attacks take advantage of certain capacity limits that apply to any network resource, such as the infrastructure that provides a company’s website. A DDoS attack aims to exceed the website’s capacity to handle large numbers of requests and prevent it from functioning properly by sending multiple requests to the attacked web resource.

Typical targets of DDoS attacks include:

  • Internet shopping sites
  • Online casinos
  • Any business or organization that relies on providing online services

How Does A DDoS Attack Work?

The number of requests that network resources such as web servers can simultaneously serve is limited. In addition to the server’s capacity limit, the channel connecting the server to the internet also has a limited bandwidth/capacity. Whenever the number of requests exceeds the capacity limit of any component in the infrastructure, the service level is likely to encounter one of the following issues:

  • Responses to requests are much slower than usual.
  • Some (or all) user requests can be completely ignored.

Usually the attacker’s main goal is to completely prevent the normal operation of the web resource, that is, to achieve complete “denial of service”. The attacker may also ask for money in exchange for stopping the attack. In some cases, a DDoS attack may also be an attempt to damage a competitor’s reputation or damage its business.

Using Botnet “Zombie Network” To Do DDoS Attack

The cybercriminal sets up a “zombie network” of computers, often from which he spreads viruses, to send an enormous number of requests to the targeted resource. The scale of the attack can cause the victim’s web resources to be overloaded, as the criminal can control the actions of all infected computers in the zombie network .

The State Of DDoS Threats Today

In the mid-2000s, such criminal activities were quite common. However, the number of successful DDoS attacks is declining. This decrease in DDoS attacks is most likely due to:

  • Police investigations resulting in the arrest of criminals worldwide

What Is A DDoS Attack?

What is a DDoS Attack? Well, a DDoS is a collective term for several different attacks that can occur. The attacker has a common purpose in mind when they carry out these attacks. They usually do it to test or gather information on the victim’s systems. Some of these attackers might want to gather information on the business systems so that they can take advantage of the system. However, there are also others who just want to test the waters.

 

It is important for you to know the various types of attacks so that you can know what is best for your company against them. Generally, there are two types of DDoS attacks – Layer 1 and Layer 2. There is also what is called the unintentional network attack. While there is no true difference between these two, they are still taken under the same categories because they all have the ability to affect your systems. There are many mitigation methods that you can choose from in dealing with these attacks.

 

There are two types of mitigation options that you can take. You can either use firewalls to prevent hackers from accessing your systems or you can use software to prevent the DDoS attackers from attacking your systems. In both cases, you need to make sure that you prevent the DDoS attackers from accessing your devices. There are two things that you can use to prevent DDoS attacks – software and hardware.

 

One option that you have is to block the IP address of the attacker. You can do this by using port forwarding. This is a very good option because the attacker will not be able to use the same device to send their packets to yours. However, this might not be very effective if the devices used to send the attacks are not of high quality.

 

Another option that you can take is to protect your system from DDoS attacks using a cloud service. Cloud services are becoming more popular especially with the release of the so-called “2021” technology. This technology is designed to prevent DDoS attacks by flooding them with too much traffic. The problem is that there are many companies offering cloud services and some of them might be experiencing DDoS attacks. If they are then your data is likely being targeted.

 

You can prevent a DDoS attack by making sure that your network devices are not vulnerable to attack. For example, you should disable the Shared folder on all your network devices. This is because if anyone is able to exploit the weakness of the shared folders then they can create multiple copies of the application which means that the application can be easily hacked into and taken advantage of. Therefore, you should make sure that the applications are not vulnerable.

 

Another way of preventing a DDoS attack is by taking a proactive approach. If you are able to identify the activity of an attacker before it takes place then you can stop it. For example, if you are using load balancers for your website then you should ensure that you have disabled them for the time being. This will prevent any DDoS attack to occur as you will be able to stop any attack to your server just by taking the necessary preemptive steps.

 

If you are using DDoS attacks frequently then it is advisable that you get the help of a security analyst. A security analyst has the training required in detecting, preventing and mitigating DDoS attacks. There are many companies that provide training in DDoS defense but you should contact a handful of such companies for the best advice regarding DDoS protection.
