Is CDN mining machine safe

1.

mining is the use of bitcoin mining machine, which is used to earn bitcoin

one of the ways to get bitcoin is that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce

mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it's only hd6770, can surpass the single graphics card of most users

and this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Considering the hardware price and other costs, there is a considerable expenditure in mining

bitcoin mining process:

1. To find the ore pool

to start mining, there must be a ore pool with convenient operation and stable output. Its function is to subdivide the data packets for each terminal, and pay the corresponding amount of bitcoin according to the proportion of the data packets calculated by the terminal through precise algorithm

2. Download bitcoin miner (software)

in fact, there are many kinds of this miner, you can go to the official website to download

3. Setting mining software is a green software. After installation, we can set the language first to facilitate further setting. Next, you need to set the server, user name, password, equipment and so on. Generally, the server chooses a better network from BTC guide series, and the user name and password are set by ourselves before

4, bitcoin mining start

when we confirm that all settings are correct, click the "start mining" button to start bitcoin mining, and then the graphics card will soon enter the full speed running state, the temperature and fan speed will increase, you can monitor the state through gpu-z or graphics card driver

2. The full name of CDN is content delivery network. Content distribution network. The basic idea is to avoid the bottlenecks and links that may affect the speed and stability of data transmission on the Internet, so as to make the content transmission faster and more stable
through a layer of intelligent virtual network based on the existing Internet, which is composed of node servers placed everywhere in the network, the CDN system can re direct the user's request to the nearest service node in real time according to the network traffic, the connection of each node, the load status, the distance to the user and the response time and other comprehensive information
high defense CDN aims to accelerate the website, at the same time, protect against DDoS, CC, web application attacks, malicious traffic brushing, malicious crawlers and other behaviors that endanger the website, forming a distributed security acceleration network
advanced anti IP proct is a paid value-added service to solve the problem that Internet servers (unprotected hosts) are not available after being attacked by high traffic DDoS. You can configure DDoS advanced anti DDoS IP to drain attack traffic to advanced anti DDoS IP to ensure the stability and reliability of the source station

after you purchase the DDoS advanced anti DDoS IP service, resolve the domain name to the advanced anti DDoS IP (Web services point the domain name resolution to the advanced anti DDoS IP; For non web services, replace the service IP with advanced defense IP, and configure the source IP. All public network traffic passes through the advanced defense IP room, and the access traffic is forwarded to the source IP through the port protocol forwarding method.
at the same time, the malicious attack traffic is cleaned and filtered on the advanced defense IP, and then the normal traffic is returned to the source IP, so as to ensure the stable access of the source IP
after configuring the advanced anti DDoS IP service, when your site is attacked by DDoS, there is no need to do additional traffic traction and reinjection.

4. High defense CDN is popular among webmasters, especially those who require high access speed. To understand advanced defense CDN, first of all, let's understand what CDN is. CDN means content distribution on the Internet. According to a layer of intelligent Internet composed of network servers with connection points in each part of the Internet, CDN system software makes the Internet content transmission faster and more stable. The advanced defense CDN is to configure DDoS advanced defense, CC protection and CDN acceleration on the basis of the original server to ensure the safe and fast operation of online business

the high popularity of high defense CDN is mainly e to the large demand of customers for such procts. With the rapid development of Internet technology, customers have higher and higher specifications for network information security. It is the trend of all kinds of high defense security service providers to customize high defense CDN services for customers indivially

What are the advantages of advanced prevention of CDN

one or more nodes, intelligent transformation, even if a high defense node is killed, it can automatically switch to another high defense node for protection in one second< Second, cache can't attack the source network server immediately, and the source network server is less affected< Third, the total traffic is on CDN, and the network bandwidth requirement is reced

in fact, website security also depends on the actual situation. If your website visits is not big, and for the site reliable operation regulation is not very high, you can consider choosing advanced defense server. But for the large number of users and high speed requirements, it is suggested that you choose high defense CDN

using advanced defense CDN can not only protect the website server from being attacked, but also improve the website access speed and hide the real IP. It is also very simple and fast to use. After binding the website domain name and the website server IP in the CDN background configuration, a resolution record value will be automatically generated, and then the website domain name can be resolved to this record value. Because the website domain name is not resolved to the website server IP, the website server IP will not be exposed to the public network, Hackers can't know what the IP address of the website server is, so they can't attack the website server<

the advanced anti DDoS CDN nodes are deployed in various regions. After using the advanced anti DDoS CDN, visitors can visit the website when they visit the CDN node. The Intelligent DNS will automatically assign nodes to let visitors connect to the node with the fastest response speed, so as to solve the problems of network bottleneck, congestion, delay and so on caused by cross regional and cross operator

website content is distributed to CDN nodes deployed in various regions, and all the cacheable content is cached on CDN nodes by the high-speed cloud advanced anti CDN caching technology. Visitors do not need to request data from the website server when they visit the website, and they will request data from the website server when there is no content on the CDN node, which reces a lot of access pressure on the website server

after using the advanced defense CDN, the website server is hidden in the back end. The attacker can not attack the website server, but can only attack the CDN nodes deployed in the front end. When the attack traffic is detected, it will be automatically intercepted and cleaned. Moreover, it can make targeted defense strategies according to different attack ways of the website program to more effectively defend against attacks, Even in the case of attack, it will not affect website access.

5. Very simple, anananbao speed CDN, as the name suggests, is a better acceleration effect of CDN. Unlike the traditional CDN, which only serves large websites, anananbao speed CDN accelerates web applications of different scales and is easier to use and operate.

6. After the website is configured with SSL certificate, Google's Chrome (e.g. v43.0 version) browser will appear "encrypted with outdated encryption suite" when accessing HTTPS. How to make Chrome browser use "encrypted with new encryption suite" needs to upgrade the new SSL encryption suite and change some settings in the web server configuration document, Enhance the security of HTTPS (prevent it from being recognized as an outdated encryption suite by chrome)
this article is to teach you to specify the "new" encryption suite, which meets the requirements of chrome and the "a" standard of SSL labs (it is actually the SSL server test website)< The reference materials are as follows:
http://www.oschina.net/translate/strong_ ssl_ security_ on_ Nginx (there is a very clear description in the data)
after the configuration is changed, you can https://www.ssllabs.com/ssltest/analyze.html Test your own site's SSL security rating report
for example, for users using Apache, please click httpd-ssl.conf (configuration file about SSL).

7. This depends on whether your defense traffic value is larger or smaller than the attack traffic value launched by your opponent. If it is smaller than the attacker's traffic, you will be paralyzed. When the server is attacked by DDoS, don't panic. The network security monitoring system will detect the abnormal changes of network traffic and give an alarm. After automatic detection or manual judgment, the IP address of the attacked virtual machine can be identified. At this time, the anti DDoS attack function interface of the system can be called to start the traffic cleaning of the attacked IP.

8. Do not open CDN, there is no direct relationship, if the promotion point after opening the page loading speed, you can consider. There are many functions that affect web pages. Opening CDN is only a method. The final good or bad depends on the results after opening.

9. The advanced defense CDN is adjusted according to the service type and attack problem; The advanced defense server is the default defense mechanism
the advanced defense server adopts stand-alone defense or cluster defense, and the attack is directly on the source server; The advanced defense CDN can disperse these attacks to each node and rece the pressure of DDoS attacks to a low value
the advanced defense server is to deploy hardware firewall in the computer room to protect through simple traction, and the traffic is concentrated in a node; The advanced defense CDN can allocate multiple nodes, and the effect is remarkable. The advanced defense CDN can hide the IP of the source server, and improve the response speed of the website.
