Chapter 120 The War Without Smoke
The top floor of the Sifang Building, the office lobby, a huge office area consisting of more than fifty desks, and IT elites in their 30s formed a powerful defensive army. They stared intently at the LCD screen and monitored the game server running. data movement.
Server operation and maintenance is their profession, and their main responsibilities are to be in charge of game server technical maintenance, monitor the server to deal with abnormal conditions, and ensure the normal operation of the game server.
'Xinghua International' has a lot of money and is willing to spend a lot of money on hardware facilities. It has purchased thousands of blade servers and built a large number of server clusters in the basement server room. The server is monitored and maintained.
In order to protect the normal operation of these servers, Xinghua International spent a lot of money to design an underground computer room, equipped with two sets of backup power systems, and a telecommunications fiber optic network. At the same time, it spent a huge sum of money to purchase the world's top firewall, and the protection measures are almost foolproof.
However, if the seemingly simple server operation and maintenance work encounters malicious hackers, artificial defense capabilities will become extremely important.
"Mr. Chen, many abnormal files were found in the jboss directory of server 21, do you want to block the network!" The silent office hall was suddenly broken by a nervous voice.
"Kick No. 21 out of the server cluster immediately!" The technical supervisor, Chen Fan, was taken aback and ordered quickly.
"Understood!" The technician took the order and immediately began to operate on the computer.
"What's the content of the abnormal file?" Chen Fan walked behind the technician.
"Multiple war packages are deployed in each file, which is equivalent to many sub-sites, and each site is a webshell." The technical staff reported nervously:
Hearing this, Chen Fan gasped and his back felt chills. This was done by that hacker. This idea is too advanced. The webshell is like an access terminal, which can remotely connect to the hacker for operations. Once it is discovered that it is too late, it will be blocked The other party connects to the webshell, and the server on the 21st is OVER.
"The other party got in through that loophole, find out quickly!" Chen Fan ordered solemnly.
"I found it, I found it, it's a loophole in the management platform." The technology reported in surprise.
"Very good, block it." Chen Fan nodded in satisfaction, and then gave orders to his subordinates: "Everyone, pay attention, and check carefully to see if there is any Trojan horse script disguised as the system jboss program."
"clear."
"Director, the second team didn't find it."
"Four groups were not found."
"..."
After Chen Fan's order was issued, he soon received reports one after another from his subordinates.
Hearing this, Chen Fan breathed a sigh of relief immediately. The servers in other groups did not show signs of being attacked by this hacker, which is a blessing among misfortunes.
"Continue to monitor, everyone can't relax their vigilance." Chen Fan confessed.
"Mr. Chen, I found something unusual here." As soon as Chen Fan finished speaking, another team member reported.
Chen Fan was taken aback, and quickly ran behind the technician. 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 overflow." The technician looked at the LCD screen and reported nervously to Chen Fan.
Chen Fan gave the technician a reassuring smile, and comforted him: "The other party is at the end of their skills and uses unexpected attacks. Don't worry about it, our firewall can handle it."
"Mr. Chen, I also have a problem here." As soon as Chen Fan finished speaking, another voice sounded.
The smile on Chen Fan's face froze immediately, and he rushed to another "fire point" like a 'firefighter'.
"Mr. Chen, it's a bit tricky. There is no false IP data. Many users' connections have been terminated without reason, and the other party has used a DDoS attack." The technician nervously reported the situation to Chen Fan while manipulating the computer.
"Let's see, it's a traffic flood attack, damn it! How many 'bots' did the other party use for such a large amount of access data!" Looking at the LCD screen, Chen Fan immediately turned dark and cursed.
After cursing, Chen Fan quickly sat down in front of the empty seat next to him, facing the computer screen, and began typing with both hands on the keyboard.
DDoS attack is a very common and disgusting hacker attack method. First collect the attack target, including the address, configuration, performance, and bandwidth of the target host, and then the attacker scans the vulnerable machines on the Internet through tools to occupy and Control a large number of puppet machines, namely "broilers", and finally the attacker issues commands to the proxy host "broilers". At this time, the DDoS attack program lurking in the "broilers" will respond to the console commands and send them to the victim host at high speed. A large number of data packets generate a flood-like amount of data, causing the victim host to crash or fail to respond to normal requests.
"..."
Various hacking methods are constantly being staged at the "Xinghua International" headquarters, and Chen Fan leads his subordinates to deal with it, and it continues from morning to night. This is an invisible war.
Aware of the tense working atmosphere in the technical department, Zhou Wenhua frequently left the office to inspect the site. Affected by the tense atmosphere, he also became uneasy.
"Ziyu, what is Xiaoxing doing in the room?" Zhou Wenhua endured for a long time, and finally couldn't help asking Zhu Ziyu who was behind him.
"Mr. Zhou, your nephew seems to be sleeping." Zhu Ziyu hesitated for a while, and reported without daring to hide it.
Hearing this, Zhou Wenhua's face turned dark, that little bastard, I'm worried here, but he hides and sleeps peacefully, he owns the majority of the shares of this game company, how can he not care at all!
"Mr. Zhou, where are you going!" Zhu Ziyu saw Zhou Wenhua leaving angrily, and hurriedly chased after him.
