Is your money stored in a bank or kept by yourself?

Many people think that a private cloud is safer if it is exposed in the center of the street and hidden in the courtyard.

Let me give you a question about how to evaluate security.

1. Alice Night Run

Hangzhou girl Alice is a marathon enthusiast. She often goes to Wentao Road on the side of Qiantang River for training at night. How much security risks do you think Alice has during night run? Let's take a look at it together?

 

What is protection? Alice, a hot and charming figure.

Who will find trouble? Staring at Alice for a few days, she wants to see the path.

Why is it dangerous? Alice couldn't beat the bad guy. She couldn't find anyone at night for help.

Okay, forgive me for being an inappropriate metaphor. Alice is a valuable asset, a vulnerable passer-by is a threat, and Alice is a vulnerability, the risk of Alice's night run is the sum and weight of the three factors.

 
If Alice looks like a flower, the bad guy may be able to get rid of the hijacking idea.

Suppose Alice is running in the gym, and the bad guy cannot get close to her.

Assume that Alice is in black band 9, and the bad guy may be down when being robbed.

So when we discuss who is more secure in public clouds, private clouds, and traditional IDCs, it is also necessary to determine who is facing greater security risks based on the importance of assets, the possibility of threat occurrence, and the severity of vulnerabilities, rather than simply looking at the bottom of the screen.

2. Sun Jiazhuang's small vault

Sun Jiazhuang is located in the provincial online near Hubei and Jiangxi in northeast Hunan, featuring elegant mountains and rivers. In 1990s, all the villagers made a living by farming. But after the village chief's second son accidentally dug up a few fluorite mines in the Houshan, sunjiazhuang's fate changed, after the identification, geological experts solemnly announced that there was a large area of fluorite mine under the mountains in the back of the village.

The appearance of the fluorite mine has brought considerable economic income to the village. The village chief stared at the bundle of banknotes locked in the office drawer, worried about the theft of the banknotes, and shouted to the village committee for discussion, the final result is to create an iron cabinet, fix the cabinet to the village committee office wall, and hide it in a dark frame. The three locks inside and outside the cabinet are added to the patrol team for inspection every day.

 
The last thing to worry about is still happening. On a rainy night in leidianjiao, the tin cabinet was stolen, and sunjiazhuang's income for three months was lost. The village committee was heartbroken and eventually decided to save all the money to the credit union to save it.

Is money stored in a bank safe? Or keep your own security? The story above tells you the answer.

One is a public institution and the other is a home. But why do you choose a bank? Because banks have established a sound risk control system and deployed ultra-high-level protection measures, even if there are many bad guys who come up with it, but the probability of success is much lower than the safe in the household. It is no exaggeration to say that the bank's vault may not even fly a mosquito.

 
The difference between public and private clouds is also here. I believe you have guessed my point of view.

Some people will mention that public clouds are exposed on the internet and are suffering from various attacks every moment, while private clouds are rooted in their own networks, and the attack frequency is far lower than that of public clouds. Why are you more optimistic about public clouds?

In fact, this only shows that the possibility of a threat is greater than that of a private cloud, but the possibility of a threat is only one of the three factors to weigh the security risk.

In this scenario, the final result of comparison will actually return to the critical factor of the severity of the vulnerability.

3. Zuckerberg and Carlisle andrewood

I believe everyone is still somewhat impressed by the news of Zuckerberg running in Beijing's haze days. In the photo, he looks relaxed, while several of the guard around him are facing the enemy. Zuckerberg is a hand-less IT Otaku. Since Facebook's rise, he has also made many enemies. Is the security risk facing him running bigger than Alice running at night on the river?

 
Obviously not. Although Zuckerberg is more valuable to others and faces more threats, he is well-equipped with various security measures, that is to say, the severity level of his vulnerability is much lower than that of Alice who runs overnight. The three factors are weighed and the security risks he faces are lower than Alice's.

The president's wife, Clare, who has also been running in the House of Cards. andrewood, she is also a perfect beauty, looking at the picture, when she was running, not only followed by a guard, but also a dedicated vehicle, you will know that the security risks of the President's night run are much lower than those of Alice.

 
In the security comparison between public and private clouds, if the assets of both parties are of the same value, the public cloud must win this victory and the vulnerability.

In fact, public clouds have done a lot of fruitful work on how to eliminate vulnerabilities.

As a public service platform, the public cloud carries a large number of customers, and the cloud services are also very different. As a public cloud service provider, delivering secure, reliable, and stable cloud services for users is a prerequisite for users to pay.

The security vision of the public cloud is to make customers feel at ease and make money in the dark flow of hackers.

There are thieves in the world, but you can stay out of the box and watch a group of thieves stare at you but cannot do anything about you. This is the highest level of public cloud security protection.

 
I am more optimistic about the security of the public cloud. One of the reasons is that the same security event has a different impact on the two. A serious attack on a self-built private cloud occurs, I can start from scratch, but for the public cloud, it may cause a lot of loss of customers and fatal problems of huge claims.

Security is a red line for public clouds.

 

In terms of security measures, private cloud may say that I should try it. I will do my best to solve this problem after I have finished two months. These scenarios will not appear in the public cloud, and safeguard measures are all political tasks that must be done by the public cloud.

This is one of my thoughts on public cloud security. Of course, there is still a rational analysis to support this point of view. Next we will continue to talk about it.

4. A few more words about traditional IDC

Many people may wonder why you only talked about the comparison between public and private clouds. What about traditional IDCs? Have you forgotten?

Of course, I did not forget to officially answer the question that traditional IDCs do not care about security. In IDCs, the security responsibilities are borne by the hosting customers themselves.

 
Are there any security IDCs? Young man, you are still a pattern. When you watch the video buffer, what will the window play and advertisement.
