Soldier Lee Cheol-woo (6)
The security program created by Corporal Cheol-woo Lee was successfully upgraded, but Jo Hyuk, who was dispatched from KISA, did not relax.
‘I don’t know where and how the attack will come from.’
With that thought in mind, I checked the existing security system.
‘First of all, NAC is working normally and there is no problem, and the same goes for the web firewall… … . Well, there’s no big problem with the intranet network.’
As I kept checking, I noticed something strange.
‘what? Was this security program supposed to work like this?’
Cheol-woo uploaded a program that integrated several security programs running on military servers. Of course, other security programs have also changed a little.
‘weird? What version is this?’
Jo Hyuk checked the version with a curious thought.
「Total Security Solution v1.0」
‘huh? what? Total security solution version 1? Is this your first time seeing it? What happened?’
Team leader Cho Hyuk continued to search for information.
‘Couldn’t the North Koreans have planted this? it won’t be… … . No, only girls.’
While searching for information, I came across a copyrighted phrase.
「Copyright (C) 2011 Cheolwoo Lee all rights reserved. Copyright for Cheolwoo Lee all rights reserved.」
The name of Lee Cheol-woo was listed in the place where the copyright was specified.
‘huh? Cheolwoo Lee? ah? Come to think of it, did you say that you are uploading an integrated security program? It must have been in the middle of a frenzy.’
Team leader Cho Hyuk couldn’t help but be more and more curious.
‘Then Cheol-woo made this integrated security program? hmm… … ? Is that possible?’
It has been two months since Lee Cheol-woo was dispatched to the Cyber Command. And the task given during that period was to create a patch for NAC’s vulnerabilities.
But in the meantime, creating an integrated security program made no sense at all.
“Me…… Mr. Cheol-woo?”
“yes?”
“Is this TSS 1 version just uploaded?”
“Yes. I was going to create a patch for the NAC vulnerability, but I saw too many vulnerabilities while making it, so I thought it would be better to create a new one.”
“Cheol-woo really made this?”
“Yes, it is.”
“No…… This, web firewall, NAC, and intranet firewall are all secured? It can also prevent attacks such as SQL injection and XSS.”
“Yes. That’s right. Looking at them, there were vulnerabilities, so I fixed them all.”
“Is that possible?”
“Um, I guess it worked?”
“…”
Team leader Cho Hyuk forgot what to say.
‘What the hell is he doing?’
And he thought to himself.
Apparently, the Commander issued a security contest and his report was great. But that was just about it.
I thought that the vulnerability could be found by anyone with a little ingenuity.
Jo Hyuk thought Lee Cheol Woo was lucky.
Still, he did not ignore Lee Cheol-woo. Because I thought luck was part of skill. So I made a scout offer, and I wanted to raise it myself in the future.
‘… … ? How the hell did you come up with a program like this in two months? No, aside from making a program, you mean that you have supplemented all previously unknown vulnerabilities, right? No, no, making a program isn’t even the second best dog.’
Jo Hyuk’s mind continued to get more complicated.
‘How the hell does that happen?’
No matter how much he thought about it, it was something that could never happen with Jo Hyuk’s common sense. However, I have experienced this phenomenon firsthand. Confused.
Meanwhile, Cheol-woo opened his mouth.
“Uh, North Korea planted a backdoor? It just got deleted.”
“yes?”
I heard a strange noise once more.
* * *
While looking around the newly uploaded TSS, I found a new fact.
‘this… … ? Isn’t it a backdoor?’
Isn’t this a bit too much?
How did the North Koreans plant the backdoor? And you continued to neglect this without knowing it?
It was suffocating.
Of course, not all military secrets leaked out with that backdoor alone, but the hole was likely to continue to grow.
This was a serious security threat.
“What do you mean? North Korea planted a backdoor?”
“Yes. TSS caught the existing backdoor. Would you like to take a look at the logs here?”
“…… Wait a minute. Let me do some analysis.”
Team leader Cho Hyuk immediately went back to his seat and tapped on the computer.
“Yes. It’s a backdoor.”
And the commander watching over it.
“……? What did you just say?”
“There was a backdoor planted in the military server.”
“Crazy? There was a backdoor planted?”
“Yes. That’s right… I’m also a little shocked.”
“No, then how far did the secrets escape through that backdoor?”
“We’ll have to do a little more research on the exact details, but our current guess is that it’s a top secret. I’m guessing that military secrets haven’t been leaked.”
“Huh… should I say fortunate out of misfortune?”
The level of military secrecy was divided into top secret, second secret, third secret, and top secret.
Each secret was something that would pose a significant risk to national security if leaked, and confidentiality was not to that extent, but to the extent that it would be embarrassing to know.
“Yes. If it was left undiscovered, there was a risk that even military secrets might be leaked.”
“Ha, I’m so glad you are. So how did you find that backdoor?”
“Corporate Cheol-woo was caught by the updated security program.”
“……? No, then just updating the NAC to neutralize the attack isn’t enough, does that mean that the existing attack was also caught?”
“Yes. That’s right. There were more than one or two backdoors. Of course, it couldn’t penetrate the primary firewall. Not only that. It seems that all other unknown vulnerabilities were also supplemented.”
“Is that possible?”
The commander also asked with a puzzled expression.
“It’s impossible.”
“So what’s the situation now?”
“I’m not sure either.”
“…”
“There is one way to explain this situation.”
“what is that?”
“genius.”
“huh?”
“Corporal Lee Cheol-woo… is a genius. That was also a gift from heaven. There’s no other way to explain this situation.”
“Genius… hahahahaha! hahahahaha! Amazing, really!”
The commander laughed loudly as he left the room.
From noble mtl dot com
“No. I’m just a little bit good at it. What is a genius…”
“hahahahaha! Genius Lee Cheol-woo! hahahahaha!”
The commander did not stop laughing at what made him so happy.
It was in the meantime.
The representative of the security company hurriedly joined the first control team.
“Did you call Lieutenant General?”
“When was the last time I called you, come out now!”
“Sorry. I have some urgent business.”
“No, that’s fine. Go ahead.”
“yes?”
The head of the security company asked with a puzzled expression.
“It’s okay, I don’t need it anymore, so I’m telling you to go.”
“Uh… well…”
He seems to have not grasped the situation properly yet.
“This corporal has replaced all the useless security programs you guys made, so go away now.”
“Yes? What do you mean?”
“Now, how many times will I have to tell you that I don’t need the security programs you deliver?”
“No! Brigadier General. Where are you doing this all of a sudden?”
“Suddenly? I’ve told you from before? Be thorough with security. But I couldn’t find the vulnerability of NAC properly, so I made the soldiers rely on it, and because of another vulnerability, they even hacked into North Korea. Is that all? And a very military server. Didn’t you turn it into a room for the North Korean army?”
The commander seemed to have exploded what had been piling up until now.
“yes?”
“The back door is also planted.”
“… How? Did you know? There’s a backdoor? Did you find it?”
“Corporal Lee.”
“Corporal! Lee Cheol-woo!”
“Is there anything you want to say?”
hmm? Suddenly giving me a say? why?
So, shall we just say something?
“Um, then I’ll just say something. CEO Kim Ki-hwan. How did you just say that you knew that? Are you saying that you knew that a backdoor was planted? But did you say you neglected it? Aren’t you communicating with North Korea by any chance?”
In fact, it is absurd nonsense.
“No……? What kind of nonsense is that?”
“That’s right. When I found a vulnerability, you accused me of being a hacker. They said they could only see something. Didn’t North Korea open the backdoor for money?”
When I said that, the Commander’s look at the head of the Security Company changed.
I’m really a soldier at times like this.
“……. What are you talking about.”
“Well, that’s just what I said. Commander, from now on military security will be taken care of by my TSS!”
“Jangha-kun. Corporal Lee.”
“No. I just did my part.”
“hahahaha, yes, the future of our Republic of Korea is bright because of Corporal Lee. Aide.”
“Yes. Commander.”
“Contact the Defense Security Command and rob him.”
“all right.”
oh, that’s scary It’s the Defense Command.
I said that there is no one who doesn’t come out of dust after shaking it off… … .
At this point, I was a little scared. If it turns out that I was responsible for the hacking scandal then… … . Just imagining it was terrifying.
“Commander.”
I ate big. Decided to report this.
“Yes, Corporal, what else do you have to say? Yes, I will listen to anything this Corporal says.”
“I have a confession to make, Commander.”
“what?”
After taking a break, he opened his mouth again.
“…… Actually, I am the culprit in the hacking commotion.”
“huh?”
“uh?!”
“to?”
Everyone there was amazed.
“No…… What are you talking about? Hacking?”
“Yes. To be honest, I was so bored when I was on duty, so I connected the external internet… I did some internet.”
what punishment will be imposed
I closed my eyes, but the answer that came in was exciting.
“hahahahaha! Yes, if you’re bored, you can do something. What a big deal! It’s important to block the hacking attack and block the backdoor now! Isn’t that right? Lim Lim?”
“Yes! That’s right. Originally, security activities require hacking, right?”
“That’s right.”
When Lim said this, team leader Jo Hyuk agreed.
“Sorry! I will be punished sweetly.”
Still, with this atmosphere, I won’t go to full song… … .
“hahahaha! Yes, I should punish you, um…… Yes, a one-day holiday limit would be nice. I’ll suggest it to your commander. And this time, I’ll give you 14 nights and 15 days of vacation for stopping North Korea’s cyber attack.”
“to……?”
It was unexpected.
A contest was even held because of the hacking commotion I created.
Clearly, it meant that it was such a big event, and I was thinking about full-time.
But is it only a one-day vacation limit?
Well, from the commander’s point of view, rather than having NAC hacked, is that a much bigger achievement than having to defend against North Korea’s cyber attacks and even remove backdoors?
Perhaps this will be more helpful for the promotion to Commander.
Oh, come to think of it, there must be nothing like that. Because of the advanced barracks culture or something, it was also a trend that we don’t send out military chanting often these days.
Lucky for you.
“Corporal Lee Cheol-woo.”
“Corporal! Lee Cheol-woo!”
“From now on, don’t use that talent in strange places, but use it to help the country and its people.”
… … . what is it This feeling, this emotion.
have you been forgiven? Or do you trust me
probably both
“all right.”
I will never do anything stupid in the future.
I reflected once more.
