How to protect the network from DDOS? Some large companies are definitely afraid of whether the protection measures for their websites are in place, whether there will be viruses or network attacks. Because of the epidemic at the beginning of the year, more and more people visit various websites, and the income generated by Internet companies will also increase, followed by malicious attacks by bad elements. The final result is that the website cannot be opened due to the attack, the website users get stuck while visiting, or the website cannot be opened directly, which is a fatal blow to the operators.
Everyone knows that the cost of defense is relatively high, and the cost of attack is small, and most of the attacks are due to malicious competition. Many people think that others will hit me, then I will fight back, so I would rather choose the low cost The attack method is to attack back instead of taking measures to protect against DDOS, but when will the injustice be reported? If it is an industry with large business traffic, it is often attacked and the business is affected and the loss is very large, so the most fundamental solution is to take network security protection measures.
Many people's understanding of DDoS attacks is that they have no technical content and can only be regarded as entry-level. This recognition often makes it easy for them to ignore its existence and automatically ignore its horror. However, the DDOS threat seriously affects the development of corporate information security. Hackers use low attack costs and a large number of botnet resources to frequently attack companies, send a large number of malicious access requests, occupy server resources, consume bandwidth and CPU memory, and cause website downtime. Unable to open, business suspension, causing economic losses.
And not only companies, but also in various parts of the world, hackers launch cyber attacks, DDOS attacks, etc. every day. Some advanced hackers use DDoS attacks to carry hidden viruses and ransomware, causing the leakage of corporate core data and information, which seriously affects the Internet. The development of information security has also caused huge losses to the reputation of enterprises.
The easiest and most direct ways to protect DDOS
The first is to avoid viruses and Trojan horses carried by the server due to misoperations, and to become a zombie broiler for hackers, as well as to avoid leaking IP addresses. The easiest way is not to download applications of unknown origin, and do not click to receive them randomly. The unknown link received in the mail, and the server mail sending function is not used;
The second is to install and update patches regularly, fix vulnerabilities, close and delete unused ports, ensure that the server adopts the latest system, and properly set up routers and firewalls, and manage permissions;
The third is to use high-defense IP to protect against DDOS attacks. High-defense IP is mainly to hide the source site IP as a substitute, filter and clean malicious attack traffic, and then forward normal access requests to the source site IP through port protocol forwarding. This is to ensure that the source site IP is not affected, and that it can operate and access normally and stably.
The fourth is to use the distributed storage of high-defense CDN, as well as the key management technology of load balancing and global network, to provide users with efficient nearby principle-based content distribution services. To hide the user's origin site IP, substitute cleaning, filter malicious visits, in order to avoid attacks directly hit the origin site IP.
The above protection against DDOS can play a certain protective role. However, hacker attacks have a diversified trend, and multiple attack methods and methods are often mixed in one attack. Companies need to resist such fierce attacks. It is not enough to rely on a single type of equipment. It is the right choice to do as many protection methods as possible.
