In the guesthouse.

Don't Changan smiled helplessly, and lay down on the bed.

Tang Wan sat next to him, looked at him and asked, "What are you doing?"

Don't Chang'an said lightly: "Sleep." ”

"You're going to sleep here?"

"And where do I sleep?"

Tang Wan smiled and said nothing, lying next to Bei Chang'an.

Lonely men and widows, living in the same room.

Don't Chang'an want to say that you don't have any ideas, that's unrealistic.

Although he is now in his 30s, his body is a 20-year-old man.

Right now, the woman of his dreams is lying in front of his eyes.

In addition to kissing Fang Ze, what he wants to do more is to spend a good night together.

But this is the first time after all.

Isn't it a little too fast?

Don't Chang'an looked at the ceiling, and when he was thinking nonsense, Tang Wan suddenly held his hand and whispered, "I want to take off my clothes and sleep......"

What you don't want to hear, what comes.

Don't Chang'an's heart was on fire, nodded, and turned around.

Bursts of aroma, accompanied by Tang Wan's dressing, rushed to her face.

That picture, don't Chang'an's brain made up, but he felt that his heart was beating faster.

……

……

……

Night.

Tang Wan covered the quilt, and she didn't know whether she was asleep or awake.

Don't Changan got up lightly and went to the bathroom to wash his face.

When he came back, Bei Chang'an was still enthusiastic and hugged Tang Wan gently.

"Why don't you sleep yet?"

Tang Wan turned around and asked.

Her hair, scattered on her delicate collarbone, is fresh and seductive.

Eyes facing each other.

In the next second, Don't Chang'an kissed deeply.

After a while, Tang Wan moved her lips away, put them to Bei Chang'an's ear, and said with a wry smile: "It's inconvenient for me." ”

Don't Chang'an's heart sank, and the high-rise buildings were destroyed in one fell swoop.

It's night, no words.

……

……

……

On the weekend, on the way back to school, Bei Changan and Tang Wan received a call from Yao Jianjun.

On the phone, Ah Fei told him that the server of "Computer Manager" was hacked.

Don't Chang'an was a little blind, drank milk and asked, "Make it clear." ”

"The data of the killing software is a bit abnormal, and the upload rate of the computer room has become very slow, so I think someone should have done it. ”

Don't Changan let out a sigh and said lightly: "Don't panic, you speak slowly." ”

Yao Jianjun calmed down and continued: "I've been feeling wrong lately, and it wasn't until I checked the port this morning that I found something abnormal. ”

"How many times a day does our database be backed up?"

Yao Jianjun replied: "Three times a day, I am afraid that someone will inject vulnerabilities, so the backup has been done very diligently. ”

Hearing his words, Bei Changan immediately said: "You wait for me in the company, I'll be there soon." ”

"Good!"

Hung up the phone, don't Chang'an told Tang Wan about the phone on the phone, as for the art festival, he shouldn't be able to help much today.

However, don't Chang'an promised her that she would definitely accompany her when she had time.

sent Tang Wan away, Don't Chang'an called the dog and Su Xiao, and the three of them went to the company together.

It's not a trivial matter for the server to be hacked, who is the other party?

Is it blackmail?

Or is there another purpose?

At present, none of these questions are known.

Not long after "Computer Manager" was released, it was targeted?

If the other party is trying to make money, then it is easy to do, and it should be ruined to avoid disaster.

If not, the problem can be a bit serious.

As soon as he arrived at the company, Yao Jianjun gave Bei Changan a detailed introduction to the situation.

Don't Chang'an wanted to hear Su Xiao's advice, so he said, "Sixth, what do you think?"

Su Xiao looked at the host screen, thought for a while, and asked, "Third brother, is there a gateway?"

"Yes. ”

Su Xiao continued: "Add a gateway, do physical isolation first, and connect the server to the intranet. ”

As soon as his words fell, Don't Chang'an told Ah Fei to get it.

Then, Su Xiao pulled over a chair and operated in front of the computer for a few minutes, and then said, "Dog, go and restart the server." ”

Don't Chang'an gestured to him, and the dog turned around and went to the computer room.

Don't Changan looked at the computer screen and asked, "What's the situation now?"

Su Xiao stared at the host and replied, "The server is still accessible, and it doesn't feel like being attacked by DDOS or something similar." Third brother, your three servers have been running naked?"

Bei Changan nodded, and asked again: "Is there a way to solve it?"

Su Xiao rubbed his chin and muttered, "There are two situations, one is to be attacked. Second, it was treated as a broiler. But in this case, you can occasionally connect to it, and you can operate it occasionally, and the program is normal, so it is estimated that it is treated as a broiler. Because if it is attacked, such as being attacked by DDOS, then the chance of connecting to the first place is almost non-existent, and the program is almost hanging. ”

Don't Chang'an asked, "What does broiler mean?"

Su Xiao explained to him: "The broiler is a remote computer with the highest management authority, and to put it simply, it is a puppet machine, controlled by people. ”

After a pause, Su Xiao pointed to the parameters on the screen and said, "The broiler can be win, Unix/Linux and other systems.

It can also be a company's server, or even a military's computer, as long as you have the ability to hack in and control it.

In a general sense, broilers are generally servers with Win2K systems with port 3389.

To log in to the broiler, you must know 3 parameters: the IP of the remote computer, the user name, and the password. ”

After the server reboot, the situation didn't change.

Don't Chang'an called a few people to the office to discuss countermeasures.

Ah Fei and Gouzi don't know much about server attack and defense technology.

Don't Chang'an, just a little understanding.

Su Xiao is stronger than the three of them, out of hobby, he understands many principles, but the company's server attack and defense, he is very calm and don't say anything about Chang'an, he can't do it himself, he doesn't have that level.

Don't Chang'an let him ask Wu Ming to see if there is no way, if he can handle it, invite him to come, the money is easy to say.

Su Xiao agreed, turned around and left the office, ready to call Wu Ming and ask about the specific situation and how to solve it.

On the phone, Wu Ming said that there are many solutions for broilers, but they should be treated differently and cannot be generalized.

Don't Chang'an mean, I want to invite him over.

But Wu Ming did not agree, saying that he only acted online and never met people in private.

But in the end, he still gave Bei Changan an an idea.

One, close the door and beat the dog.

If you open the firewall, it is estimated that you can block a large wave of attacks, and the service should be normal. But you may not be able to find the reason for the attack.?

Second, first find out the cause of the attack and solve the source of the attack, of course, this will definitely solve the problem.

But the second point is that it is too difficult, mainly because the server is basically unconnected.

With the occasional connection, it takes a long time to find out the cause.

On QQ, Wu Ming demonstrated the process to Bei Chang'an, first need to sort out the ports that the program needs to open, and then write the script to set the port and roll back the script.

Then there is the need to pass the local test, otherwise there will be a production accident.

The scariest thing is probably that the SSH port is messed up and then scrapped.?

Finally, deploy it online and test whether the business is normal.

Don't Chang'an think it's quite reliable, after all, this way, it takes less time, so for the company's business, the loss is also the smallest.

ended the conversation with Wu Ming, don't Chang'an a few people

Then it's time to divide up the work and do it separately.

Su Xiao sorted out the port.

The dog goes to find information to see how to view the problem of being attacked.

Ah Fei is adding a gateway to do physical isolation.

Don't Chang'an was not idle, she called Yuan Lai and asked her to come forward to do some public relations, don't let the problem ferment.
