There are so many attacks that have become the routine in the digital world. Since individuals, enterprises, businesses and organizations; everything is online; you cannot say that you are completely safe. You need to be sure that you know about the attacks and threats that are there in the online world. After covid19 pandemic, since everyone has been compelled to have online presence, more and more attackers are looking for their victims. The point is cyber-attacks are on the constant increase and if you are not taking the precautions and using the right security solutions; you could be the next prey.
There are many attacks and talking about DDoS attack or denial-of-service attacks they have been a part of the toolbox of attackers and criminals for nearly two decades now. The unfortunate part is that these attacks are becoming stronger and more prevalent.
What is this distributed denial of service attack all about?
A distributed denial of service (DDoS) is a type of attack when a criminal or attacker or even attackers, try to make it impossible for a specific service to be delivered. Such a thing can be attained by thwarting access to virtually any type of thing like that of devices, services, servers, networks, applications, and even particular type of transactions inside applications. In a DoS type of attack, it is one system that is going to send the malicious data or makes the request. Remember that a DDoS attack emerges from different systems.
In a general sense, these attacks act by drowning a system with specific requests for data. This might be sending web server manifold requests to serve a page that it actually crashes under the demand. Similarly, it might even be a database getting hit with a high volume of queries. The outcome is available internet bandwidth, overall CPU and RAM capacity turns out to be overwhelmed.
Here if you are thinking about the impact of all this, it might range from a small annoyance from disrupted services to that of undergoing entire websites, applications, or even that of whole business taken offline.
3 Types of distributed denial of service Attacks
Well, there are three main types of distributed denial of service attacks. These are like:
Volume-based attacks
These are the attacks that use massive amounts of bogus traffic to overpower a resource like that of a website or server. These can include ICMP, UDP and even that of spoofed-packet flood attacks. The size of a volume-based attack is evaluated in bits per second (bps).
Protocol or network-layer attacks
These are the attacks that send large numbers of packets to the specific targeted network infrastructures and infrastructure management instruments. Such protocol attacks encompass SYN floods and even that of Smurf DDoS, amidst others, and you can measure their size in packets per second (PPS).
Application-layer attacks
These attacks are the attacks that get conducted by flooding applications with unkindly crafted requests. The size of application-layer attacks gets evaluated in requests per second (RPS). For every single type of attack, the aim is always the same: Make online resources slow or fully unresponsive.
Are there any symptoms of DDoS type of attacks?
DDoS types of attacks can look like various of the non-malicious things that may trigger availability issues – like that of a downed server or system, too various legitimate requests from legitimate users, or even that of a cut cable. It mostly asks for traffic analysis to decide what is exactly occurring.
The tools used in DDoS type of attacks
Characteristically, DDoS types of the attackers rely on botnets – gathering of a network of malware-infected systems that are controlled centrally. Such infected endpoints are generally computers and servers, but are growingly IoT and mobile devices. The attackers are going to harvest these systems by classifying vulnerable systems that they can infect through phishing attacks, maligning attacks and other mass infection methods. Growingly, attackers are also going to rent these botnets from those who constructed them.
The evolvement of DDoS type of attacks
As just mentioned briefly above, it’s turning out to be more common for such type of attacks to get conducted by rented botnets. You can see this trend to continue for a long time now. And if you are not doing anything about your security, you may be the next victim, who knows!
Similarly, another type of trend is the use of different attack vectors inside an attack, even known as Advanced Persistent Denial-of-Service. As an instance, an APDoS type of attack could even include the application layer, like that of attacks against databases and even that of applications as well as directly on the server. This is something that goes even beyond flooding.
As per some experts, you should know that the attackers mostly don’t simply directly target their victims but even the entire organizations on which they rely such as ISPs and cloud providers. Remember that these are broad-reaching, that of high-impact attacks that are properly coordinated.
Well, it is even changing the influence of DDoS type of attacks on organizations and expanding their danger. The point is businesses and companies are no longer just concerned with DDoS type of attacks on themselves, but even attacks on the huge number of business partners, vendors, and even that of overall suppliers on whom such businesses depend. The point is a business is as weak as its weakest link. In the present time (the weakest link of a business could be the usage of third-parties.
Clearly, since the criminals and attackers perfect their DDoS type of attacks, the technology and even methods will not stand still. The point is, the addition of fresh set of IoT devices, increase of machine learning and AI are all going to play a role in altering these attacks. Moreover, the Attackers and criminals will eventually mix these technologies into attacks too, making it all more challenging for defenders to draw near with DDoS type of attacks, exactly particularly the ones that cannot be ceased by simple ACLs or that of signatures.
