On the top floor of the Sifang Building, in the office hall, in a huge office area composed of more than 50 desks, IT elites in their thirties form a powerful defensive army, they are intently staring at the LCD screen, monitoring the data movement generated by the operation of the game server. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

Server operation and maintenance is their profession, and their main responsibilities are to be responsible for the technical maintenance of the game server, monitor the server to deal with abnormal conditions, and ensure the normal operation of the game server.

Schmidt International has a lot of money and is willing to spend a lot of money on hardware facilities, purchasing thousands of blade servers and building a large number of server clusters in the basement server room, and their job is to monitor and maintain the servers running 'Civilization and War' through remote desktop links.

In order to protect the normal operation of these servers, Schmidt International spent a lot of money to design an underground computer room, equipped with two sets of backup power supply systems, telecom fiber optic network, and spent a huge amount of money to purchase the world's top firewall, which is almost foolproof.

However, if you encounter malicious hackers, human defense will become extremely important.

"Mr. Chen, a lot of abnormal files have been found in the jboss directory of the No. 21 server, whether to block the network!" The silent office hall was suddenly broken by a nervous voice.

"Kick No. 21 out of the server cluster immediately!" Chen Fan, the technical director, was startled and hurriedly ordered.

"Understood!" the technician took the order and immediately started operating it on the computer.

"What's the content of the anomalous file?" Chen Fan walked behind the technician.

"There are multiple WAR packages deployed in each file, which is equivalent to many sub-sites, and each site is a webshell. The technician nervously reported:

Hearing this, Chen Fan gasped, and a chill ran down his spine, this was done by the hacker, this idea is too advanced, the webshell is like an access end, which can be remotely linked to the hacker's side to operate, once it is found late, it is linked to the webshell by the other party, and the server on the 21st will be over.

"The other party got in from that loophole, find it out quickly!" Chen Fan ordered with a solemn face.

"Found it, found it, it's a management console vulnerability. The technical surprise reported.

"Good, plug it. Chen Fan nodded with satisfaction, and then left his subordinates empty, and ordered: "Everyone pay attention, pay attention to check, whether there is a Trojan script disguised as the system JBOSS program." ”

"Understood. ”

"Director, the second group didn't find it. ”

"The four groups didn't find it. ”

“……。 ”

After Chen Fan's order was issued, he soon received a series of reports from his subordinates.

Hearing this, Chen Fan immediately breathed a sigh of relief, the servers of other groups did not show signs of being attacked by this hacker, which was a blessing in misfortune.

"Keep watching, you can't let your guard down. Chen Fan explained.

"Mr. Chen, I found an abnormality here. As soon as Chen Fan's words fell, another member of the team reported.

Chen Fan was taken aback, and quickly ran behind the technician, and after seeing the LCD screen, he breathed a sigh of relief.

"The other party used a data-driven attack, causing a large amount of data to overflow. The technician looked at the LCD screen and nervously reported to Chen Fan.

Chen Fan gave the technician a reassuring smile and said comfortingly: "The other party's donkey skills are poor, and he actually used an unexpected attack, don't worry about it, our firewall can deal with it." ”

"Mr. Chen, I also have a problem here. As soon as Chen Fan's words fell, another voice sounded.

The smile on Chen Fan's face froze immediately, and he immediately rushed to another 'fire point' like a 'firefighter'.

"Mr. Chen, a bit spicy, there is no fake IP data, many user connections are terminated for no reason, and the other party uses DDoS attacks. While controlling the computer, the technician nervously reported the situation to Chen Fan.

"I'll see, it's a traffic flood attack, damn it!With such a large amount of access data, how many 'broilers' did the other party use!" Glancing at the LCD screen, Chen Fan's face darkened and he scolded.

After scolding, Chen Fan quickly sat down in front of the vacant seat next to him, facing the computer screen, resting his hands on the keyboard and 'crackling'.

DDoS attack is a very common and disgusting hacker attack method, first collect the attack target, including the address, configuration, performance, bandwidth of the target host, and then the attacker scans those vulnerable machines on the Internet through tools, occupying and controlling a large number of puppet machines, that is, "broilers", and finally the attacker issues orders to the proxy host "broilers", and at this time ambushes in the "broilers" In response to console commands, the DDoS attack program sends a large number of packets to the victim host at a high speed, generating a flood of data and causing the victim host to crash or fail to respond to normal requests.

“……。 ”

All kinds of hacker attacks were constantly staged at the headquarters of "Xinghua International", and Chen Fan led his subordinates to cope with it, from morning to night, continuously, this invisible war of gunpowder.

Sensing the tense working atmosphere of the technical department, Zhou Wenhua frequently left the office and inspected the scene.

"Ziyu, what is that kid doing in the room?" Zhou Wenhua endured for a long time, and finally couldn't help but ask Zhu Ziyu behind him.

"Mr. Zhou, your nephew seems to be sleeping. Zhu Ziyu hesitated for a moment, and did not dare to report it in concealment.

Hearing this, Zhou Wenhua's face turned dark, that little bastard, Lao Tzu was worried here, but he hid and slept peacefully, he accounted for the majority of the shares of this game company, how could he not care at all!

"Mr. Zhou, where are you going!" Zhu Ziyu looked at Zhou Wenhua and left angrily, and hurriedly chased after him.
