Domestic idle server mining
-
all public cloud manufacturers explicitly require that they are not allowed to use the cloud server for mining, otherwise they will be banned
-
GPU is mainly used in mining. At present, GPU servers provided by public cloud manufacturers are more expensive, which is not cost-effective, so it is better to use special chips

of course, some hackers intrude into the server through vulnerabilities, implant mining programs and scripts on it, and carry out mining operations, but this is illegal in itself
a new customer recently consulted with sine security company, saying that his server often fails to open the website of the card, and the remote connection to the server is extremely slow. Sometimes the Ping value reaches 300-500, and he often switches. After listening to the customer's words,
will generally judge that he has been attacked by CC + DDoS mixed traffic, It's strange to say that there is no traffic attack on the computer room. It's not a traffic attack, but it also causes the server card and website to fail to open. What kind of attack is this? In order to solve the problem of
client server card, we immediately arranged a security engineer to carry out security detection and deployment on his Linux server
{rrrrrrr}
Mining Trojan horse is also designed. If the mining process is forced to stop by customers, it will automatically start to continue mining to achieve uninterrupted mining.
careful inspection shows that it is through setting the hourly task plan, remotely downloading shell mining Trojan horse, and then executing, Check whether the current process exists or not. If not, start the Trojan horse to mine
a detailed security inspection was carried out on the client's Linux server. It was found that fortunately, there was no encrypted server data, and the worm was infected with the disease through the security detection and analysis of our security engineers, we found that the server uses Apache Tomcat environment, the open architecture of the platform is JSP + Oracle database, and Apache Tomcat uses the version of 2016, which leads to the serious remote command execution vulnerability of Apache, Through this vulnerability, the intruder can directly invade the server and get the administrator permission of the server,
virus. If the data was encrypted, the loss would be great. The client was a platform, and the client's data was very important. After finding out the mining Trojan horse,
do customers need to know how the server is attacked? Was the Trojan horse uploaded? It can prevent the attack
in the later stage
sine security engineer immediately repairs the Apache vulnerability and clears the Trojan horse. So far, the problem has been solved, the client server
runs stably, and the network station opens normally
Absolutely
if you change your profession, you can't waste your talents only if you are engaged in related instries.
you don't have to go to mine operation to engage in design work or information system management.
there is still a choice for related professional work.
and now there is no choice Quality graates have good employment prospects. Don't give up

the essence of business activities is the transaction and integration of resources. Just like the two sides of a coin, transaction and integration are also the two sides of business activities. Every transaction is accompanied by a new resource integration, and the goal of transaction and integration is to enhance or maximize the value. There are roughly three forms of transaction and integration, namely business activities: market, enterprise and cooperation. The market is a form of transaction, and the enterprise is also a form of transaction (of course, it is more complex), while the "collaborative" business organizations between the market and the enterprise (such as strategic alliance, virtual enterprise, outsourcing, etc.) are booming
depending on the specific application scope, e-commerce can be divided into three types: market application, enterprise application and collaborative application. However, the application of e-commerce should not be limited to the local areas of business activities (such as website e-commerce or network marketing), because the integration of business activities inevitably requires the integration of e-commerce
the term "e" in e-commerce refers to e-commerce technology. Is it possible to realize e-commerce by combining e-commerce technology with the above business activities? The answer is not simply "yes" or "no", the key is how to combine. Please see the following two formulas:
e-commerce ≠ e + commerce
e-commerce = e-commerce × Commerce
the two formulas mean that e-commerce is not a simple sum of e-commerce and commerce, but an effective integration of e-commerce and commerce; The combination of e-commerce and e-commerce does not necessarily lead to higher efficiency and efficiency of e-commerce. On the contrary, if the combination is not good, the efficiency and efficiency of e-commerce is even lower. Therefore, it is not appropriate to continue to define e-commerce as "concting business activities through computer network", and it is necessary to make some amendments to the concept of e-commerce:
e-commerce: business activities based on computer network and effectively integrated with it
throughout the development of business activities and even the whole human activities, information technology has been accompanied by them. Every progress of business activities is accompanied by the progress of information technology. Information technology and business model have formed an effective integration system in the continuous evolution. Certain information technology always matches certain business model. Changing information technology without changing business model is tantamount to letting the train run on the road, just increasing the cost in vain, It can't bring efficiency and benefit. Therefore, the "business" in e-commerce is no longer the original business activity mode, but an evolved business mode matching with e-commerce technology
in essence, e-commerce is not only an application of tools or methods, but also a new business model, and any business model is a social division of labor under the technical and institutional conditions of the society at that time. A good business model is bound to promote social division of labor, improve the efficiency of social proction and transformation, and then promote social and economic development. However, in the actual process, there is a very complex interaction between business model and social division of labor, which makes it difficult to complete the design of any successful business model completely in people's minds, books or study, It can only be completed through social organization experiments, and through continuous experiments, it can be affirmed, improved or negated, so that the new business model can be evolved. All kinds of business models we see now, such as department stores, chain stores, wholesale markets and strategic alliances, are the procts of experimentation and evolution
both theory and practice have proved that experiment and evolution are the only way to promote development when facing and dealing with a complex system containing many interactions, such as e-commerce model. Based on this understanding, we can understand why the application and development of network economy and e-commerce often do not develop in the way we expected, often fail where we think it is bound to succeed, but surprise us where we do not hope. We should treat the setbacks and failures of network economy and e-commerce with a common attitude, like understanding the process of human evolution
this does not mean that we can give up rationality, nor does it mean that everything becomes so unpredictable and controllable. On the contrary, we can promote the development of e-commerce in a more correct way. We should abandon the rigid organization and business form that is only suitable for mature business model, and replace it with flexible organization and business form. We should "embed" the experiment and evolution function to find a successful e-commerce model faster and at a lower cost
in some major directions, the evolution of e-commerce is predictable:
- e-commerce will move from imitation to innovation, and there will be more and more business models that are not found in traditional commerce, exemplified by the development of online advertising
- the models of e-commerce will become more and more diversified, and become more and more complex in the process of integration with traditional commerce. The so-called "B2B" and "B2C" and other over simplified model classification will soon become history
- e-commerce model innovation will graally expand and deepen from business process innovation to management innovation, and then to organizational innovation, which is an evolutionary process of interaction, agitation, chaos and self-organization.
