Soldier Lee Cheol-woo (1)
Minseok and I went to a quiet cafe nearby.
“Why? Something to say?”
“Ah, I have something to tell you. Did you hear the story?”
“Blue light?”
“uh.”
“I was listening, though I don’t quite understand what you’re saying.”
“Ugh, I’m really worried. What do you do when you have that good skill?
“What! I’m Hogu?”
“Yes! Hogu.”
“…… No, I’m Hogu.”
“It’s because I’m worried. I’m worried. You’ll need to know some of these things in the future.”
Well, how many more of these things will happen in the future?
I don’t know if I live in style, but shouldn’t I at least not live with it?
I’ll have to build up some knowledge on that too.
“……. I know.”
“Anyway, as for how it ended, I’m going to do promotional activities over there in the blue light. At the same time, I’ll have to do marketing.”
“Oh, I understand that much.”
“And if it hits the jackpot, you could touch a lot of money. You or the blue light.”
“Ohh?”
Touching a huge amount of money, just imagining it made me happy.
“But you don’t know if it will hit the jackpot or not. You won’t know until you try it on the market.”
“Um, won’t it work?”
“Of course, from now on, it seems to be going well, but I don’t know what kind of ambush there will be.”

“for example?”
“For example, UX, you know that Android and IOS have guidelines for UX and UI, right?”
“I don’t know?”
“Ugh, anyway, there’s that, but the CAK you created ignores it and builds an app, so it could be more inconvenient for users than I thought.”
“Oh, um. I guess so.”
That’s why the game side seems to have more cross-platform development tools.
“Of course not, and we don’t know yet.”
“Sure.”
“Anyway, that’s not what I want to say right now, it’s that the business will go on without any loss because the blue light promotes it.”
“I see, isn’t it completely honey?”
“It’s honey.”
“By the way? What’s the matter?”
“If there’s a problem, it’s in the future, CAK, how do you say it went well. But what about other programs or technologies you’ll make?”
“Don’t you know? Have you ever thought about it?”
“No, let me ask you one thing before that. Are you going to continue this job after graduation?”
“Hmm… I’ve never thought about that, but maybe I’ll continue?”
“What is that vague answer?”
“It seems like they’re good at development, but what if it’s fun? I wonder if I’ll try other things first.”
“Something else?”
“Well, I haven’t thought deeply about it yet, but the first thing that comes to mind right now is the hardware side, or the security side, or even the machine side.”
“I see…. There are many things I want to do. Then, are you interested in business?”
Since it’s a business, am I going to become the president and lead the company?
“Well, I’ve never really thought about that too much.”
“Hey, don’t you want to make a lot of money?”
“Of course I want to earn a lot, but there are so many things I have to take care of to run a business. As you said, you have to do marketing, manage employees, and take care of your business partners.”
If you do business, wouldn’t it be too bothersome?
“…”
“I just need to eat well and live well.”
“Then you must have a lot of money.”
“It’s good to have a lot of money.”
“You have to be in business to make a lot of money.”
“I just said it, I thought it would be difficult? It’s annoying. It seems like your head hurts, and you don’t seem to have any talent for business. Even if you only get a blue light job, you’ll be treated well and you’ll get a lot of salary. Isn’t that enough to make a living? Ugh… Actually, I just wish I had won the lottery.”
“Lotto? Actually, I hope I win too.”
“yes?”
“Ah, the story leaked to a strange place again.”
“So what the hell do you want to say?”
What on earth does Minseok want to say?
“Actually, I think I’ve found my aptitude.”
“Huh? Aptitude?”
“Yeah, I felt it while going around with you, I think I’ll have to do business.”
“Business? Do you have items?”
“It’s an item, you just have to find it.”
“Then how do you run your business?”
“I don’t know yet, but doing business or managing things seems to suit my aptitude. I learned about it while signing with Blue Light. From the hair salon.”
“Ooh, that’s great.”
“So I’m going to finish this semester and transfer to the Department of Economics and Management.”
“Because it’s economic management, oh… it suits me better than I thought.”
“And one more thing, do you want to do business with me?”
“Eh? Business?”
“I’ll take care of everything that bothers you, you just have to do what you want to do.”
“Oh, are you saying that if I do what I want to do, you’ll turn it all into a business?”
“I can’t give you a definitive answer yet, but I’m trying to improve my skills so that I can.”
“Hey, it’s cool. Cha Min-seok!”
Minseok seems to have found his true aptitude. I wish I could find some aptitude too.
“I wanted to say that, I’m a freshman now and I don’t know what will happen in the future, but I thought I’d regret it forever if I didn’t say it now.”
“hahahaha, yes then. Let’s do business together.”
“A promise?”
“Yes, I promise!”
As a result of hanging out with Minseok for the past few months, he seemed like a trustworthy guy.
“And thank you.”
“what?”
“The fact that he trusted me and proceeded with the blue light contract. If you didn’t trust me, I wouldn’t have found my aptitude.”
“hahahaha, what the heck.”
“Anyway, thank you.”
“That’s okay. I also got a lot of help thanks to you.”
“Ha ha, is that so?”
“yes.”
“Okay. Then I’ll stop talking about it. Oh, and the first semester is over soon. What are you going to do in the army?”
army… … . A must-visit place for strong Korean youth.
“Um, maybe I’ll go in a little while?”
Sooner or later, I will be 21 years old. It was an age where everyone just started going.
“Okay, it’s better to go quickly instead of delaying.”
“Why? What were you thinking?”
“No, just.”
“It’s bland.”

Blue Light’s team leader Min taught how to use CAK, and Blue Light prepared for the commercialization of CAK.
However, it seemed to take some time for concrete results to emerge.
While they were doing that, I enlisted with the idea of leaving the army as soon as possible.
‘Ha, I thought I was going to die at the real training center and when I was a private and private.’
Utilizing his computer engineering skills, he applied for enlistment as a wireless equipment operator, and after a difficult training camp, he was assigned to a satellite operation station under the direct control of the Armed Forces Status and Communications Command.
As the name suggests, the satellite operation station was a unit that managed communication satellites, and the only thing the soldiers did was stand guard.
In the middle of my life as a private soldier, a new satellite operation station was established in preparation for any unexpected situation, and I was dispatched there.
And now, I finally became a corporal and became the most senior in the unit.
‘My military life went really well.’
The deputy satellite operating station had only three soldiers, and the opposite senior was discharged a while ago.
Working there was so easy. All I had to do was stand on night watch once every three days.
Even though it was just to keep the formality.
Really, even if it worked out well, I thought it worked out too well. Did your ancestors help you?
“Corporate Lee Cheol-woo. Where are you on duty today?”
Private First Class Yoon Sang-cheol, the next one, spoke to me.
“uh.”
“What are you going to do today?”
“Um…… Shall I read a book? I have nothing to do.”
The satellites were all operated by executives, and as a soldier, all I had to do was monitor the unit’s CCTV.
The unit was not an independent unit, but was located within the operational headquarters, so the facilities were well equipped.
“hahahaha, then, please do your best today.”
“Okay, rest.”
After a rough greeting, I went up to the office.
After saluting the officers, I went into the CCTV surveillance room.
Today was the beginning of a boring night shift.
I opened the book to read, but it didn’t catch my eye at all.
‘What are we doing today?’
While on duty, I did everything I could do on my own. Exercise, reading, origami, etc. There was nothing fun at all.
‘Ah, I want to play a game.’
On vacation not long ago, a game caught my eye.
‘Pentakill! Quadra Kill!’
Spend time playing games in your head.
‘… … . I don’t waste time. Should I just sleep?’
I looked at the time, it was 1:00 in the morning. Still, I didn’t go to bed until 4:00.
At that moment, I suddenly had a good idea.
‘No, could we play the game for a while?’
I thought that if I hacked the military security system, I might be able to enjoy the game during the boring night shift.
Quotes are woven in my head.
First, to play the game, you must break through the military security system, the watchman. If the intranet is already in use, the watchman is installed, and if it is connected to the external network, it will be caught immediately.
‘Okay, I guess I can use this fence PC’
The problem was easily solved. It was possible to use a computer that was not connected to both the intranet and the Internet.
‘Is the Internet network next?’
I had to pass the Internet to the fence PC.
‘Oh, there’s a terminal here, right?’
The Internet terminal box, which looks complicated at first glance, will surely connect to the Internet PC in the commander’s office.
You just need to find a good one, distribute the LAN, and connect it.
‘Shall we start working right away?’
After working here and there, it worked well enough not to get caught by the executives.
‘Hey, am I a genius?’
Sometimes when I see myself like this, I am surprisingly great.
I just connected to the internet.
「Internet not found.」
… … . However, contrary to expectations, it did not immediately connect to the Internet.
‘what is the problem?’
I searched around for more.
‘Ah, these guys are more thorough in security than I thought?’
The cause was using a NAC network access controller. It was a device that controls the user’s computer based on the accessor’s MAC address.
‘Then what do you do? I have this weakness
NAC was easily pierced. NAC, which controls based on the user’s MAC address, could easily be breached by manipulating the MAC.
‘Can it be pierced this easily?’
Is the army still an army? Look at it roughly.
「Internet connection complete.」
When the MAC address was altered, an alarm popped up on the computer saying that it was connected to the Internet.
I immediately turned on the internet.
「Please enter your user identification ID and password.」
… … . But this time, I didn’t get the result I wanted. A green window should appear.
‘What is it this time?’
I need to cancel the idea that military security is lame. It was thoroughly double-tripled.
‘Uh, I’m not sure about this, but it’s using port 80 after all, isn’t it? I think I can turn the proxy on?’
I immediately thought of how to pierce it, and put it into practice.
“search : “
And finally I could see the green window I wanted. Then I installed the game and ran it.
“Welcome to Summoner’s Rift.”
The game ran normally. I wondered what would happen if the computer performance was bad, but that was a waste of time.

‘and… … . Can I play games while standing on duty now?’
Crazy, are there all these geeky positions?
I didn’t even have to worry about taking it. I was sure I would never find it.
‘Whoops, it’s a game in the military, life is ruined!’
I was depressed thinking that I would rot more in the army for the next 8 months, but it was like a rain of drought.
‘I’d be surprised if Sang-cheol knew’
His replacement is Private First Class Yoon Sang-cheol. He said that he came to the army late after working for security when he was in society.
can you tell me this?
They’ll be bored too, should I tell you if you do something pretty? No, I should just know that this is something proud.
As we continued to play, the time went well.
It was morning and it was time to finish work.
Then my mind flashed.
‘By Bored… … . Hacking the military security system, I must be crazy for a moment. What if you get caught even one in a million? I won’t do it again.’
I guess I was really crazy.
After restoring it to its original state, I promised myself in my heart that I would not buy it again.
And a week later, Yoon Sang-cheol, my successor, said something strange.
“Corporal Lee Cheol-woo. Did you hear the rumor?”
“What rumors?”
“They said the Armed Forces security program was breached this time.”
“Eh? Really? How did you know that?”
“There are some people I know at the cert.”
CERT, in English, was another word for Cyber Command.
I heard that you studied information security when you were in this society.
“……So you found the culprit?”
Maybe it’s not because of me? No matter how much he played games, the news wouldn’t have reached Sang-cheol. Obviously there must be some other reason.
“No, they say it disappeared without a trace.”
“okay?”
“So this time, we are holding a security program vulnerability contest.”
Vulnerability contest What else is that?
