1- TCP SYN flood, 2- ICMP foold --> which are DoS attacks 3- Ping sweeps, 4- Port scans --> which are Reconnaissance attacks
Stateful packet inspection
The four types of electronic attacks include malware attacks, where malicious software is used to disrupt or gain unauthorized access to systems; phishing attacks, which involve tricking individuals into revealing sensitive information through deceptive emails or messages; denial-of-service (DoS) attacks, aimed at overwhelming a system to render it unavailable; and man-in-the-middle attacks, where an attacker intercepts and alters communication between two parties without their knowledge. Each of these attacks exploits vulnerabilities in technology and human behavior to compromise security.
Intruders ,attacker,or some time user who want to destroy server and its application. After DoS attack server and their application are not able to respond.
Most network Denial of Service (DoS) attacks are distributed (DDoS) because leveraging multiple compromised devices amplifies the attack's scale and impact. By coordinating numerous machines, attackers can overwhelm target servers with a higher volume of traffic than a single source could generate, making it harder for defenses to mitigate the attack. Additionally, distributed attacks can obscure the origin of the attack, complicating detection and response efforts. This makes DDoS attacks more effective and challenging to counter.
To mitigate DoS attacks, organizations can implement Intrusion Detection Systems (IDS) and Firewalls. IDS can monitor network traffic for unusual patterns or signs of attack, allowing for quick response. Firewalls can filter out malicious traffic based on predefined rules, helping to block unwanted requests before they reach critical systems. Additionally, using rate limiting can help manage the number of requests a server processes, reducing the impact of DoS attacks.

DoS attacks can be carried out in 2 different ways: by flooding devices or crashing them. Flood assaults happen when a system receives too much traffic for the server to buffer. It may slow down and eventually shut down the server. The following are some of the most common floods: Buffer overflow attacks – A buffer overrun is the most common DoS tactic. The goal is to send more data to a network interface than the engineers expected. ICMP flood – exploits vulnerable network devices by sending bogus packets that ping every machine on the targeted network instead of just one. SYN flood – sends a server a connection request but does not complete the handshake. Other DoS attacks exploit weaknesses in the target system or service to bring it down. These attacks involve receiving input that exploits the target’s vulnerabilities, leading the system to crash or become considerably destabilised, making it hard to access or use.
Attacks from a single source can be easily defeated with an IP block. Thousands of different IPs make this a much more difficult attack to stop.More sources means more computers. More computers means more computing power. This is especially useful for DoS attacks, where the more requests you can send out the better your attack is.It's much harder to find the original source of an attacker when there are many attacks from different physical locations.

Very far, there is no remedy against botnets and DoS attacks.
According to CISCO's 2021 Cybersecurity Threat Trends report, Crypto jacking, Phishing, Ransomware attacks, and Trojans are the most active threats with around 100 million queries each month. Of course, there are other cyber threats that potentially harm internet users and these threats keep evolving every second. So, here are some of the most common cybersecurity threats and what you can do to protect yourself from them.
