What exactly are DDoS attacks?
DDoS attacks are pretty common these days. Attackers target sites by sending them malicious links like malware or Trojans or by overwhelming the victim’s network with sudden and unexpected traffic. DDoS attacks aim at bringing the victim’s site down and disrupting their online service, which further leads to a loss of business and harm to the company’s or brand’s reputation.
It is extremely important to understand DDoS attacks and keep a check on DDoS attack map to know who is getting targeted online. It also helps you to ensure that your site is not getting hit and to be prepared in case you become someone’s target at some point of time.
DDoS attackers are an online group of criminals who do all they can to attack computer networks by overwhelming their targets with more traffic than they could handle. Often they leverage the asymmetric power of a botnet to drive the illegitimate traffic and disrupt your online service through bandwidth-hogging.
DDoS attacks, better known as distributed denial of service (DDoS) attacks are used by cyber criminals to bring down websites, network services and company networks. They mostly aim at disrupting a computer, program or network service for its users.
Though they are difficult to handle and can cause a denial of service for days or weeks, depending on their intensity, you can still protect your site against DDoS attacks with these prevention methods. IT professionals can easily defend their sites against DDoS attacks by strengthening their networks and software or by blocking any attacker who sends that traffic.
Protect Network Servers
Most DDoS attacks are based on the concept of overwhelming force. Network servers are capable of handling only a finite amount of network traffic. DDoS attackers generate greater traffic than your network servers can handle so as to overwhelm the server and disrupt your service. Often the traffic is illegitimate. What you need to do to prevent a DDoS attack is to keep a check on DDoS attack map and protect your network servers by blocking all illegitimate traffic from entering your network.
Close unnecessary open DNS resolvers
There are a total of approximately 27 million open DNS resolvers in the world. The firms and organizations must close all unnecessary open DNS resolvers in the world. If they do so, DDoS attackers would not be able to make use of these DNS resolvers against victims on the internet.
Secure and Harden all DNS Servers
All DNS servers must be secured and hardened. The DNS administrators must restrict all recursive DNS queries to their internal networks. This way we can prevent attackers from easily leveraging DNS Servers in amplifications attacks.
Prevent Spoofing on the Internet
It is more important to prevent spoofing on the Internet. Spoofing allows people in a network to send traffic that looks like it is coming from a different person. This acts as an advantage to the DDoS attackers who play with it to show what they want on DDoS attack map and divert traffic to victim site.
DDoS attacks are to be taken more seriously. Even the non-IT people must understand them and the ways to prevent them so as to make the internet a safer place.
