Alibaba cloud is mined

1. LCS is a decentralized digital currency of the blockchain. The smart contract of the blockchain can't be tampered with. Combustion means that the more mining, the less it is. All of them are absent from work. They release three times of their investment. Now they release 1.2% every day. The earlier you dig, the more you dig,

2. It should be calculated according to the actual situation. If the manager of the platform insists on doing it even though he knows that he has violated the law, then it must be a kind of fraud. Knowing the law and violating the law add one more crime. Do you understand!, Of course, criminal liability may not be so serious, but joint and several liability is absolute. In the case of police interrogation, one has to identify himself as a victim, just a small manager

3. Of course, if you don't believe it, you can search their official website on the Internet and have a look. I have done digital currency mortgage in their bank

4. You need to find out the type of attack first, to see whether it is DDoS and other physical attacks or CC attacks. Physical attacks can only use advanced defense server. If it is a software virus, it can be resisted by daily security protection

5. Alibaba cloud provides infrastructure services and uses server resources on demand. However, security defense enterprises must also pay attention to it. They should not think that they are absolutely safe after they are on the cloud. Alibaba cloud provides up to 5g free defense against DDoS traffic attacks. If the security policy is higher, they need to buy advanced defense IP
your situation should be that there are no better security measures when you are attacked. When the attack reaches a certain level, the staff will shut it down to prevent greater losses.

6. Attack or invasion? You can use alicloud's CDN to attack, and you can find the guardian God to invade.

7. It's not a rational way to turn off the computer to avoid attack. And also very unreliable, so that the sub site simply can not run normally
if the server is attacked, it is recommended to check the system log of the server and the running log of the website, analyze what type of attack it has suffered, and then decide which server should mediate and adopt the corresponding security policy to defend it
you can also install protection software such as safety dog for defense
server security dog mainly protects the server from malicious attacks, including DDoS, ARP firewall, remote desktop guard, port protection, network monitoring, etc
the website security dog mainly protects the website on the server, including online horse scanning, SQL injection protection, CC attack protection, resource protection, etc
the protection directions of the two are different. It is suggested that combined use can make the protection more comprehensive
at the same time of defense, you can check the protection log to understand what types of attacks the server and website are subjected to, and then adjust the protection rules according to the types of attacks, which can be more effective for defense.

8. In fact, the core problem of DDoS is that the cost of initiating DDoS is very low, while the cost of protection is very high. As far as I know, there should be more than 200g DDoS attacks in China this year. Most of the domestic companies are unable to withstand, of course, there is no deep hatred or huge business purpose, and they will not launch attacks of such scale. But at present hang up an ordinary website has a few G can, attack cost only a few hundred, protection may need dozens of times, some may not be able to defend live. Before my personal website was DDoS, the other side on a g, and then I was unplugged. Many IDC export just a few g, a dozen to hang up, a few times down, and then they let you move out of the computer room. It seems that the protection provided by Alibaba cloud is 5g. The building owner has been attacked by a black hole. I feel that the traffic attacking you should exceed 10g. Since Alibaba cloud publicly announced that it would provide 5g free DDoS protection, several other domestic cloud protection manufacturers have basically erased the parameters of DDoS protection and dare not make a positive comparison. You can learn about the parameters and prices of anananbao and accelerator. DDoS is really a big threat to the Internet. Protecting DDoS is not as simple as sealing IP understood by the building owner. To seal the traffic of this IP can only be sealed at the source of attack at the end of telecom operators. If the operator is not blocked, the attack traffic will flood your server address like a flood. IDC and alicloud can't stop these traffic from flowing to them. In any case, the traffic is pouring into IDC's compound, and the next goal is to rush to a door. IDC either cleans up the traffic and keeps the website under attack normal access, or it has a black hole. DDoS protection is to analyze the normal access and malicious attacks in these floods. The cleaning capability is limited. Alibaba cloud provides 5g. If it exceeds 5g, it will be a black hole. The unlimited cleaning cost is very high, and it will also affect other Alibaba cloud users< In addition, the owner may have misunderstood the usability. In fact, when your website was attacked, the virtual machine was still working, but the network was blocked.

9. To prevent the Alibaba cloud server from being attacked:
first of all, the internal security of the system should be well done, the system vulnerability patch should be well done, the firewall policy, which ports to open, which IP to allow, these basic settings should be well done
using some professional security vulnerability scanning tools, alicloud has its own security analysis tool called situation awareness, which can analyze and discover potential intrusion and highly covert attack threats
some management tools can be used to manage Alibaba cloud hosts. It is very convenient to manage Alibaba cloud hosts. You can set the permissions of management members to prevent management confusion, rece the opening of external ports, and check the security vulnerabilities
when encountering DDoS attacks, you need to buy third-party anti DDoS services. In Alibaba cloud market, there are some anti attack procts such as yunn DDoS, Neusoft, server security reinforcement and optimization.
