This article will explain in detail what the role of ddos firewall is, the content of the article is of high quality, so the editor will share it for you as a reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

Turn the website into a static page

Making the website into a static page as far as possible can not only greatly improve the anti-attack ability and security of the website, but also bring a lot of trouble to hackers, at least so far the overflow of HTML has not appeared. At present, several portals in China, such as Sina, Sohu, NetEase and so on, are mainly static pages.

(2) increase the number of servers and adopt

DNS round-robin or load balancing technology requires the purchase of layer 7 switch equipment, so that the ability to resist DDOS attacks is doubled. As long as the investment is deep enough, it can effectively defend against DDOS attacks.

(3) adopt a security strategy at the source of the attack.

The defense against DDOS attacks must be solved through the cooperation of various groups and users on the network to develop more stringent network standards. Every network device or host needs to update its system vulnerabilities, turn off unwanted services, install necessary anti-virus and firewall software, and pay attention to system security at any time.

(4) adopt encryption technology

For game service providers, high-intensity encryption algorithms should be adopted in game communication protocols to improve the authentication mechanism and make it more difficult for attackers to simulate.

(5) optimize routing and network structure.

This is an ideal coping strategy. If users have enough capacity and resources for hackers to attack, they will gradually lose their energy when they continue to visit users and seize users' resources, and hackers may not be able to do so before the users are killed.

(6) use enough machines to withstand hacker attacks

If you are managing not just a host, but a network, you need to adjust the routing table to minimize the impact of denial of service attacks. In addition, UDP and ICMP packets that the network does not need to use are prohibited from passing, especially outbound ICMP "unreachable" messages should not be allowed.

About what the role of the ddos firewall is shared here, I hope that the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
