A denial of service (DoS) attack is an attempt to cause harm by making a target system, such as a website or application, inaccessible to ordinary end users. Attackers usually generate a large number of packets or requests, which ultimately overload the target system. To carry out a distributed denial of service (DDoS) attack, an attacker uses a variety of hacked or controlled sources.
Protecting ourselves from DDoS attacks
Anti-DDOS is an open source project designed to protect against DOS and DDoS attacks. The necessary protection configurations are used and works only on the Linux operating system, but is fully compatible with it.
Let's go back to Zerobot, which was originally reported by Fortinet two weeks ago.
The Internet of Things (IoT) botnet is a self-replicating and self-propagating malware written in the Golang (Go) language and aimed at more than twelve architectures, with a wide range of distributed DDoS capabilities.

🧑💻 Scientists carried out the first cyberattack without the participation of people
The malicious code was created using the Text-to-SQL model, which is capable of deceiving NPL models of natural language processing and leading to the theft of confidential information and DoS attacks.
What are DDoS attacks and why is it harder to defend from year to year
According to the NETSCOUT Threat Intelligence active threat level analysis system, the largest number of attacks that our partners have ever seen occurred during the pandemic — 4.83 million DDoS attacks in the first half of 2020 (15% more than in 2019). And the frequency of DDoS attacks increased by 25% in the period from March to June.
However, it is worth noting that the number of single-vector attacks in the first half of 2020 decreased by 43% compared to the same period of the previous year. And the number of complex multi-vector (15+ vectors) attacks have increased by 126% over the past year and by 2851% since 2017.
methods of combating DoS/DDoS attacks
Your morning starts with reading bug reports and analyzing logs. You update the software daily
and update the firewall rules hourly. Snort is your best
friend, and Zabbix is your invisible assistant. You have built a real bastion, which
cannot be approached from any side. But! You are completely defenseless against the most
insidious and vile attack in the world - DDoS.
Distributed Network Attacks / DDoS
Distributed network attacks are often referred to as Distributed Denial of Service (DDoS) attacks. This type of attack uses certain bandwidth limitations that are characteristic of any network resources, for example, the infrastructure that provides conditions for the operation of the company's website. A DDoS attack sends a large number of requests to the attacked web resource in order to exceed the site's ability to process them all... and cause a denial of service.
How to protect yourself from DDoS attacks?
How to protect yourself from DDoS attacks, what steps to take? First of all, it is not necessary to postpone it "for later". Some measures should be taken into account when configuring the network, starting servers and deploying software. And each subsequent change should not increase vulnerability from DDoS attacks.
