How to protect against a DDoS attack?
Still known as distributed denial of service attacks, DDoS attacks are becoming more and more sophisticated in the air where the Cloud is currently used more. This recurrence of the practice generates enormous repercussions in the entrepreneurial universe where companies are exposed to exponential costs. Fortunately, today there are techniques that one can adopt to protect themselves from DDoS attacks.
What is a DDoS attack?
The denial of service attack or DDoS attack (Distributed Denial of Service attack) is a practice that consists of making a service unavailable in order to prevent its access to users. In a world marked by Big Data and the increase in the number of commercial exchanges on the Internet, denial of service attacks (DDoS) are becoming more and more recurrent.

Indeed, these attacks are likely to target both a specific computer, a service or an entire network that are disabled. They can affect printers, alarms, phones or laptops as well as system resources such as disk space, bandwidth, processor time or routing information. They can also create security problems at the operating system level and expose it to malfunctions.
Methods to protect against a DDoS attack
In view of these numerous consequences, which can prove to be very costly for companies, it is urgent to take adequate measures to guard against distributed denial of service (DDoS) attacks. One of these provisions is to identify warning signs. It's about being alert for signs of an impending DDoS attack, such as network performance drops, abnormal traffic, connectivity issues, and more.
Then, a mitigation solution must be put in place. You can check with your Internet Service Provider (ISP) or your hosting provider to find out if they have DDoS mitigation solutions. These solutions can detect DDoS attacks in real time and block them before they affect your network. You also need to put in place a professional-grade firewall. In addition to helping you filter and block malicious traffic; this method can help identify and block attack source IP addresses.
Other solutions to protect against DDoS attacks
Bandwidth needs to be increased. This is to ensure that the network used has sufficient bandwidth to deal with a possible DDoS attack. An increase in bandwidth can help absorb some of the malicious traffic. Also, if you are a business that experiences frequent DDoS attacks, consider using a third-party DDoS protection service. These specialized DDoS attack mitigation services can help mitigate the effects of the attack by routing legitimate traffic and filtering malicious traffic.
The standard also recommends setting up a redundant architecture to protect against DDoS attacks. For example, if your DNS server is attacked, your website may be offline. By implementing a redundant DNS architecture, using multiple DNS service providers, or deploying DNS servers in multiple data centers, you can reduce the risk of denial of service. Performing regular backups is also an effective solution to combat these attacks. Be sure to back up all important data regularly. So in the event of a DDoS attack and potential damage, you can recover data quickly.
