Strange traffic, coming from one IP address or various but similar IP addresses (same range of addresses).There are specific characteristics of each DDoS attack type, but in general, what you can expect during an attack is: It could be money or just satisfaction with the success of the attack. The bad actors could have achieved different goals, and now they get their reward. Normal users will not be able to use the server until the traffic drops again and the server can begin responding to normal queries. It will start to deny service and stop working. There is a limit to how many active connections a server can have, even if it is very powerful. After a while, if the target does not have DDoS attack protection, or it is not strong enough, eventually it won’t be able to function correctly. There are different reasons for the attacks, but the goal is to saturate the target with traffic and take it out of service. Time for choosing a victim and sending the traffic towards the targeted server. For example, hackers can bypass the security of IoT devices, or they can send phishing emails to users, and when the users open the emails, they can get infected with malicious code. At this moment, the cybercriminals will create a network of botnets (infected devices) that later they will use for attacks. There are different types of DDoS attacks (volume-based attacks, protocol-based attacks, and application-layer attacks), but in general, they all have the same stages: DDoS attack protection could keep your business safe and notify you of problems. There are many DDoS threats, this is why you want to a DDoS defense too. Exploit the vulnerabilities of a protocol, such as the UDP or another.Occupy the existing connection and not allow new ones.Amplify attack that uses other servers to resend the traffic to a target after significantly increasing the size of the packets.Using a network of pre-infected devices (computers, mobiles, IoT devices, etc.) called a botnet.The cybercriminals can generate this strong wave of traffic by:
There are few different types, but in general, a DDoS attack is an attempt to overwhelm the target (a computer, few connected computers or a whole DNS network) with high traffic from multiple sources.
