What Is a DDoS attack? Here is the Answer.
What Is a DDoS attack?
A decade ago, DDOS was only a basic attack that trying to overwhelm connection with traffic with the aim of taking a certain web property offline. When leading web experts began fighting DDoS attack in the year 2000, the flood attacks ranged at 400 Mbps but as we speak they exceed 100 Gbps.
The attackers build a network of infected computers called botnet and spread the malicious software through websites, emails and social media. The machines are capable of being controlled remotely once infected without the knowledge of owners. These machines are then used like the army in launching an attack against the target. Some botnet are as strong as millions of machines. The floods are generated in numerous ways including sending more connection requests that exceeds what a server can handle. They can also be generated by having the computers send to the victim huge volume of random data with the intention of using up the target’s bandwidth. Some DDOS attacks are so huge that they can max out the whole country’s international cable capacity.
Beyond the democratization of DDoS attacks are the advanced techniques and targets. Today DDoS involves a series of attacks targeting multiple devices that consist of the organization’s security infrastructure as opposed to targeting connection bandwidth only. They include various applications and firewall or IPS devices that organizations rely on such as DNS, SMTP, VOIP, HTTPS and HTTP. The latest version of DDOS attack is the common multi-vector attack that combines flood, state exhaustion and application attacks against the infrastructure devices in a sustained single attack. These attacks have gained popularity due to their effectiveness and the fact that they are hard to defend against.
Today’s new realities of DDOS attack require new approaches to defense. Network experts have been in the forefront in looking for ways to combat DDOS attack for some years now. The best defensive mechanism against the modern DDOS attack is the layered approach combining cloud based protection and on-premise. With this type of protection, you are guaranteed of 100% security for your organization against the entire spectrum of DDOS attacks. A digital attack map is also ideal for protection against a DDOS attack because it displays global DDOS activities on any particular day. It displays the attacks as dotted lines that are scaled to size and stored in line with their source and the destination countries of attack traffic when they are known.
How to perform a DoS/DDoS attack (flood attack).
This DDoS attack was all done on a test network, In order to do a DDoS attack you will need more than one node. This is a basic attack, I am well aware a sophisticated attack will take advantage of amplification using different services like DNS, NTP, etc.
