Zhang Yifu sighed, got up slowly, tried his best to control the stage fright, and said: "Thank you for the opportunity to speak to the leader, I have only been working for two months, and I still need to learn and understand the overall situation of equipment, production and safety in the system, and I only have a few ideas about the automatic monitoring system of Jiutan Power Plant, and I will report to you here——"

As he spoke, he picked up the analysis materials in his hand: "After all, I have limited understanding, and I have not been to the scene, only from the materials, it is obvious that as the leading experts said, this is an accident caused by a system vulnerability, and in the solution, the experts have also given a complete way to deal with it." As far as automation technology is concerned, I personally think that when it comes to software, there are actually more intuitive and convenient solutions. ”

"Take the automation system of Jiutan Power Plant as an example, it is mainly divided into three modules, one is the centralized control system DCS, which is used to collect the underlying information, such as boiler temperature, current and voltage, etc.; the second is the power plant monitoring system sIs, which analyzes, optimizes and operates after obtaining the number of DCS; and the third is mIs, the management information system, which focuses more on enterprise management and process control. So now let's go back to the accident at Jiutan Power Plant, the direct cause is the zài loop between the mIs system and the sIs system, and a large number of useless jù are sent and piled up, causing the sIs system to crash. ”

When Zhang Yifu said this, he deliberately slowed down, wanting to see if everyone understood.

Judging from their expressions, some people seem to understand whether they understand or not, and most people still nod slightly in embarrassment, maybe they can't figure out what these three modules are, but it is enough to figure out that there are three modules.

This is the difference between Zhang Yifu and Hua Changqing, in the face of different people, he will use different narrative methods to ensure that the other party can understand the words, it doesn't matter if he is slow, otherwise he will finish talking by himself, not only will the matter not be done, but I am afraid that he will still fall into the resentment of "arrogant and lonely".

"I don't know exactly what caused the loops between the systems, but it doesn't matter, the important thing is that we can prevent such problems in the future in a very intuitive way. ”

Zhang Yifu sighed slightly: "Firewall." ”

Yes, it is the firewall, the security means that will be used by the National Security Bureau and the small Internet cafes in the county town, which are not yet popular in this era, and belong to the information security means of cutting-edge technology.

Looking at everyone's puzzled expressions, Zhang Yifu had to explain in depth: "To put it simply, the firewall is an information filter, when he has a large number of illegal numbers jù, or abnormal jù appears, congestion, it will automatically wave, temporarily block the number of jù flows, and call the police, similar to this accident, such a loop will undoubtedly be blocked by the firewall, and remind the operation and maintenance personnel to deal with it at the first time." In addition, assuming that the kind of cyber attack that Zou Gong just mentioned really appears, the firewall can also effectively block and protect it. It can be said that setting up a firewall can not only eliminate internal troubles, but also block the external line of defense and effectively ensure safe production. ”

No matter how much was said before, whether everyone understood it or not, in short, the last four words fell on production safety, and Zhang Yifu's argument immediately put on a golden vest and invisibly rose to a strategic height.

It's just that in this era when even computers are not popularized and the network is still very backward, the concept of firewall is too far ahead, and everyone present does not know how to communicate with Zhang Yifu and how to echo him.

"Firewall...... ...... firewall," Mu Zhiheng muttered and asked, "What is the English pronunciation?"

As soon as he spoke, he felt that it was inappropriate, how could an ordinary undergraduate student of the Northern Electric Academy be so professional, if it was a doctorate, he might be able to answer one or two, but for the undergraduates who had just graduated, it was too difficult, so it was better to ask Hua Changqing.

Who knew that Zhang Yifu had been waiting for this moment for a long time, and immediately replied in the standard London accent that he had practiced for a long time-

“Firea11。 ”

Mu Zhiheng was stunned for a moment, slapped his palms and said: "I remember, at this year's International Power Grid Conference, the United States mentioned this concept, yes, yes, it is Firea11, a wall of fire, a firewall, why didn't I expect it earlier!"

The rest of the people saw that the boss affirmed this concept, and then they were sure that Zhang Yifu was not talking nonsense, and they couldn't help but look at this undergraduate with exaggerated expressions, this guy is so evil that he even knows the idea that Lao Mei just proposed, could it be that he came back from studying abroad?

The throwing out of the concept of firewall even made Hua Changqing a little moved, he immediately pulled out of the confused confusion, and asked curiously: "Zhang Gong, this concept is very new in the United States, where did you learn about it?"

"The professor of our college mentioned it once in a while, and I was very interested, and then I pestered him to ask for some foreign language materials, and I studied it for a long time, and I thought it was a trend, and after reading the accident report in Jiutan, I thought it was just enough to solve the problem. ”

"Hmm......" Hua Changqing nodded, and only then did he pull the concept of firewall out of the corner of his memory.

It's not that he is blind or ignorant, but at this moment, the firewall is too new, too small, and too remote, and even God can't think of it being used in the internal control system of a power plant.

After thinking for a while, Hua Changqing raised his glasses and said: "This proposal is very constructive, and I will negotiate with the US side immediately after the meeting to see if we can provide relevant technical support." ”

The rest of the people were stunned again, Hua Changqing, who was unconvinced, and Hua Changqing, who no one wanted to look down on all the engineers in the country, was so sure of a little technician's remarks?

I don't know if the world is in chaos, or if this little technician is really a god.

Although Lao Zou didn't understand most things, he figured out one thing, this firewall still has to be imported from the United States, and he immediately grasped the appropriate argument and waved his arm: "The firewall of the United States? After all, it is still the United States, even if it gets such a thing, what if the United States wants to ...... it?"

At this time, Hua Changqing rejected his argument in an unreasonable way, only to see him raise his hand slightly, and said in a not very strong tone: "Please shut up first, now it's a technical discussion." ”

The audience was embarrassed, and Lao Zou himself was stunned.

Hua Changqing then turned to Zhang Yifu and asked: "As far as I know, even in the United States, the firewall has not been widely used in the power system, it is a network security technology, do you think it can be easily applied in the Jiutan Power Plant?"

"Yes, there are now professional firewall manufacturers in the United States, only need a box hardware connected to the computer room, maybe our software supplier Bai1ey can't provide firewalls, but we can ask them to find a firewall company to do this. ”

"For example...... Cisco?" Hua Changqing then asked.

"Or sonicaLL, as far as I know, there are only two companies that provide hardware firewalls for the time being. ”

Hua Changqing showed an incredible expression, this little guy seemed to know more than himself.

――――――――――――――――――――――――

In the new week, it will be strongly pushed, that is, it will be on the shelves on January 1st.

Putting it on the shelves means a responsibility for me, because from that second on, everyone will have to pay to read the book, and it is no longer just an attitude of appreciation and playfulness between us, but a contract, a relationship of giving and giving.

Just like a marriage certificate, that's a responsibility from the beginning.

Many friends have mentioned it before, my previous bad deeds, TJ unfinished problems and other problems, I don't deny it, those past things whether they are said or not, are in front of you, on paper, indelible, if you want to destroy these bad deeds, I can change the pen name and start over, anyway, "add mushrooms to you" is not very good, right.

But I don't, the good and the bad are all on it, it is clear at a glance, and I don't evade or deny it.

Books that don't come on the shelves are like falling in love for me, maybe I'll give up if they're not suitable, and I'll put them down if I don't get good grades, that's right, I've been TJ. And whenever a book is put on the shelves, I will start from the beginning, millions of words upwards, no water or delay, finish a story, and tell an ending.

Of course, for most of my friends, I just like the book and don't care about the past. In short, I said this, not to wash the floor or to be ambitious, but I also like this book, and I am sure that I can write it, and I hope you can read it or fatten it with confidence. I'm sorry to say that the milk powder money is on top of this. But at this time, my pleasure far outweighs the pressure, because this is a happy and simple story, an ordinary and ridiculous Zhang Yifu.

Here, ask for a reservation in advance!

See you on January 1st!

I'm going to add mushrooms for you!
