Jingle bells!

A hurried phone rang, breaking the silence of the dormitory.

Shi Weijun, who was next to the phone, picked up the phone casually and asked, "Hey, who are you looking for!" ”

"Uh...... It's Senior Sister Yan, I'm here, I'm here in July, I'll let him answer the phone! ”

In the Department of Information Security, Yan Manqing's name is definitely known to everyone.

Shi Weijun and Lu Junqi were both at UCAS in their undergraduate years, so they are more familiar with her.

Speaking of which, this senior sister is not only beautiful, but also has a very strong level of ability.

After only one stage of research, several projects have achieved excellent results, which is convincing.

And in the list of participants in these projects, without exception, there is the name Su Qiyue.

There are even two of them, and they are still ranked before Senior Sister Yan.

It can be seen that the relationship between roommate Su Qiyue and this senior sister is by no means as simple as that of ordinary classmates.

Holding down the phone microphone, Shi Weijun hurriedly beckoned to Su Qiyue and shouted, "July, hurry, Senior Sister Yan is looking for you!" Hurry up and pick it up! ”

Su Qiyue answered, got up from his seat and went over to take the phone.

"Senior sister, uh, you're already downstairs? Okay, I'll come down now. ”

Su Qiyue said a few words with a smile, and then put down the phone.

"Daqi, Weijun, I have something to go out for, in the afternoon, you take Kaidong around the school, let him get familiar with the campus environment as soon as possible!"

At the morning class meeting, Su Qiyue had been elected as the class leader.

Since he is a squad leader, of course he has to take on some responsibilities.

Lu Junqi and Shi Weijun are both "old men" of UCAS.

It is very suitable for them to bring Zhang Kaidong, a new classmate, to familiarize themselves with the environment.

After listening to Su Qiyue's orders, Lu Junqi and Shi Weijun responded again and again: "Don't worry, July." Kaidong has both of us with him, absolutely no problem. ”

Zhang Kaidong just listened to his roommate tell Su Qiyue's shocking resume, and the dissatisfaction in his heart has long disappeared.

At this time, seeing that Su Qiyue was busy going out and didn't forget himself, he hurriedly stood up and said, "Thank you squad leader for your care!" ”

Noticing his slightly nervous appearance, Su Qiyue snorted slightly, raised his hand and smiled: "Kaidong, take it easy, everyone is in the same dormitory, don't be too restrained." ”

"Yes, Kaidong, when you enter this door, you are all your own people, don't be too polite!"

When Shi Weijun heard this, he also said to Zhang Kaidong, "July is our boss, and there are definitely many benefits to following him, you will know it slowly in the future!" ”

"That's it!"

Lu Junqi also echoed and said, "July often has to be busy with Senior Sister Yan's projects, let's look forward to him going out, and he can bring us delicious food from time to time. ”

ridiculed his roommate, Su Qiyue shrugged helplessly.

In fact, although the teacher arranged a lot of projects for Senior Sister Manqing, there were not many opportunities to go out.

After coming down from the dormitory, Su Qiyue saw the senior sister standing next to the flower bed, who was more beautiful than flowers.

"Senior sister, didn't you say that Liu Yunyun's meal was changed to a different time? What's the matter, did you change your hexagram again? ”

Before Liu Yunyun, she asked Yan Manqing to have dinner with her cousin, and brought Su Qiyue with her.

But then because of something happened to her cousin, the meal was postponed.

At this time, the senior sister found herself again, and Su Qiyue was a little puzzled.

"It's not about eating, it's when I'm researching the penetration technology, and I met my opponent......"

Yan Manqing gritted her teeth and said.

Hearing this, Su Qiyue was stunned.

Regarding the fact that the senior sister began to learn the infiltration technique online, Su Qiyue naturally knew.

She also had some questions before and consulted herself.

But it's the first time I've gritted my teeth like this.

"Uh, let's take a look."

……

Graduate School of Information Security.

In the office, after Yan Manqing turned on the computer, the picture of hundreds of background load servers suddenly came into Su Qiyue's eyes.

As soon as he saw these pictures, Su Qiyue suddenly understood.

"These are all from your opponents who did 'penetration testing' on the forum, and sent them to you, right?"

Su Qiyue pointed to the picture and said.

Yan Manqing was slightly stunned, and then quickly nodded and said, "That's right!" I was in a room on the forums talking to people about 'infiltration techniques', and it turned out that this guy called 'Little Red Riding Hood' didn't know when he joined in. ”

"After hearing that I was learning to do 'penetration testing,' she threw me a license to try hacking into her system...... See if I can spot the weak points of their system. ”

After listening to Yan Manqing's story, Su Qiyue sighed and said that he understood.

The so-called "penetration test" is actually an attempt to hack into the other party's system and find its vulnerabilities with the authorization of the other party, so as to help it fix the vulnerabilities.

Looking at the number of servers with so many loads in front of him, this "Little Red Riding Hood" should be a security officer of a network company, and it is still okay to infiltrate technology.

In this era, he can be regarded as a master.

She sent Yan Manqing this invitation to "penetration testing", to a large extent, to test the security of her own system, but she really didn't just want to see her joke.

After the other party sent an invitation, the senior sister, who has always been arrogant, was helpless after a few rounds, of course, she couldn't be angry.

"In July, you said that this 'Little Red Riding Hood' was not deliberately making things difficult for people. Isn't it a needle in a haystack to find her designated backup file in so many load servers? ”

After listening to her senior sister's complaints, Su Qiyue snorted slightly: "Leave it to me, it's not a problem!" ”

Yan Manqing responded and gave up the position in front of the computer.

"Can you get in touch with this 'Little Red Riding Hood' now?"

Sitting in front of the computer, Su Qiyue asked casually.

"Yes, look at the 'Little Red Riding Hood' profile picture on my QQ, it's her."

Su Qiyue sighed, clicked the mouse, and opened the chat dialog with "Little Red Riding Hood".

"In?"

“？”

A brief question mark came back, making Su Qiyue feel like a world away.

He hadn't experienced such an online conversation for a long time.

"Source code provided!"

“？”

Another question mark.

"It's hard to test ASP or CGI scripts without source code, and it's extremely unwise for you, as a network administrator, to assume in advance that an attacker won't know the source code."

"In addition, the vulnerabilities in the web server software often expose scripts and applications to remote attackers, and there is source code, so the penetration testing efficiency on my side will be higher."

After Su Qiyue's message was sent, it took a while for "Little Red Riding Hood" to reply.

"Find the backup file I specified first, and then talk about anything else!"

Seeing these lines, Yan Manqing behind Su Qiyue had a little more annoyance on his face.

Obviously, she has not been able to find the backup file specified by the other party, which really makes her quite angry.

Keep in mind that finding an important backup file from hundreds of load servers in the background can take thousands of random attempts.

This is not something that can be done in a moment.

Yan Manqing felt that the other party's request was clearly teasing herself.

If you are a network administrator and give such a problem, the other party will definitely be fine.
