Chapter 275 CIA’s Firewall

Catherine certainly believes that the FBI is looking out for the interests of the United States.

The Internet is now popular in universities. When the east-west lines are connected, the connection from New York to California will become unimpeded, and from the Ivy League to the University of California, everything will be closely integrated.

For college students, this is a place to spread their thoughts - according to the company's survey, more than 90% of college students are interested in the Internet and believe that this thing will change their lives.

Hoover was a pioneer in the anti-communist movement. Naturally, what he wanted to do was to suppress the spread of ** thoughts among American college students. But he did not know that his approach had the opposite effect. Not only

Not only that, the normal work of CIA has also been affected.

Compared to the FBI, the CIA has a more relaxed environment. As an organization that can burn money to the point of weakness, the CIA is richer and richer than the FBI. They even have many non-white employees. For example, the famous spy money

No matter what, he has even become a high-level member of the CIA - but in the end because of the betrayal of a traitor, he was caught by the FBI and put in prison. And because of the attitude of a certain country, he had to choose "suicide" in the end.

. But whether it was suicide or suicide... Who knows, anyway, this is very common in the United States.

"Um...Okay, that's it."

Catherine hung up the phone and let out a long sigh of relief. When the final work of the magazine is completed tomorrow, Catherine will invite a professional manager to come over and take care of the business. As for Catherine, she is going to lead a small team.

Go and develop firewalls for cia.

"Miss Edson, this is the guide for "Emma Cube" I wrote." At this time, "Rebecca" walked in.

"OK, all right."

This document was written by Catherine. Being able to play "Emma Cube" to that extent was beyond the imagination of Catherine herself.

Then the other party left, and Catherine continued to work hard.

"firewall...?"

As soon as she left the office, "Rebecca" muttered, then immediately returned to normal and left.

Catherine, on the other hand, has no idea what happened, and she is in a good mood now. Because CIA has sent someone to contact her, and they seem to really need a firewall.

Firewalls have a very good protective effect. Intruders must first pass through the firewall's security defense line before they can access the target computer. However, this cannot completely prevent the intrusion of others.

Now that the CIA has enough money, Catherine is even ready to recommend a team of professional computer engineers to them to deal with these FBI.

However, Catherine has some doubts about whether cia will really hire its own people. For them, this does not seem to be a wise move. Instead of that, why not help cia cultivate a group of employees? Catherine is not sure about this matter.

That should be the case. The key lies in the attitude of the CIA itself. If they really hired their own people, that would be even better - with the CIA who burns money every day as the financial backer, is there anything more wonderful than this?

"Hmm...what kind of firewall do they need?"

The firewall needs to prevent some people with ulterior motives from querying IP addresses. This is the simplest thing. The other thing is to prevent hackers... although there are no so-called hackers yet.

Catherine was scribbling and drawing on her notebook with paper, while "Rebecca" over there took a half-day off and then left the company...

"firewall?"

"Rebecca" passed her message to Moning Bell.

The other party also looked suspicious.

...what is this?

There have always been firewalls, but few people associate this thing with the Internet. But according to "Rebecca's" intelligence, this thing does seem to be related to the Internet. This is indeed what the other party said on the phone. Moning

If Bell's guess is correct, this thing should be a piece of software.

These are not the key. The key lies in the news that Moning Bell got from the other side - the CIA was raided by the FBI.

The United States was having conflicts, and Moning Bell still felt very bad. But then he learned that the incident seemed to be related to the Internet. However, the KGB had not yet obtained more specific information.

These two things were connected in series. Morning Bill seemed to understand something, but he could not grasp anything.

However, he still handed this information and his speculation to his superiors, while he continued to investigate...

On the other side, Catherine also returned to Noah's headquarters the next day, and began to form a small working group dedicated to studying firewalls.

What Catherine is considering for cia now is not a software firewall, but a hardware firewall.

Embed the software firewall into the hardware, then embed the Phoenix system and your own firewall software system, and then connect the two parties.

Hardware firewalls are superior to software firewalls in many aspects, and today's computers are not updated too quickly, so it is completely feasible to develop hardware firewalls.

And with cia covering the research and development costs, Catherine is happy to continue developing a new product for herself.

"Miss Edson, the east-west network will be connected soon. By then we will have a huge network. At this time, the number of people our CIA will have to face will be ten times that of now. This is a very research question. We

We don’t want anyone to disrupt the situation for us.”

In the living room, Badua said this to Catherine.

"This is no problem at all. We still have two months."

The project is expected to be faster than expected. If it goes well, the east-west optical cable network will be completed as soon as the end of January, and by that time, the New York network and the California network will be completely connected.

The time of the FBI's intrusion cheered up the CIA. There are more people on the network, and if one of them suddenly has an impromptu idea, it may be bad for the CIA. After all, what their "temporary workers" did

They're all just trying to incite hatred.

"How should the firewall be arranged specifically?"

Snake, who was following Badua, asked.

"We will first develop a simple software version for emergency use, and then we will develop a complete hardware version."

"please continue."

"However, no matter how comprehensive and rigorous the hardware firewall is, once the hardware firewall is put into actual use, the situation will change at any time. The rules of the hardware firewall will always be constantly changing and adjusted, and the configuration parameters will also change.

It will change from time to time.”

"...Why did it change?" Snake seemed a little confused.

"It depends on the enemy." Catherine stretched out a finger - she was thinking of the FBI at the moment - and then continued: "If the enemy finds that their attacks have become ineffective, they will not continue to take such measures.

This is childish behavior. The other party's engineers will definitely find a way to bypass our firewall."

Both Badua and Snake nodded.

"As a network security manager, it is best to write a set of security policies that modify firewall configurations and rules, and implement them strictly. The hardware firewall configuration involved should be as detailed as what traffic is allowed and which services use proxies.

Such details..."

Catherine told them so, but the two of them seemed a little embarrassed.

"...We in CIA don't have professional network talents yet..."

Catherine was astonished.

"Why?"

"Because our funding has just been cut...many of our original plans have been postponed. But in its current form, we have decided to set up our own network management staff."

The CIA doesn’t have enough funds? Are you kidding me? You don’t take this seriously at all, do you?

Catherine believed that must be the case.

"Well... Miss Edson, can you explain to us the specific details that we should pay attention to in the network firewall?"

Catherine nodded, and then continued: "In the security policy, the steps for modifying the hardware firewall configuration should be stated, such as which authorizations need to be modified, who can make such modifications, when modifications can be made, how to record these modifications, etc. Security

The policy should also specify the division of responsibilities. For example, if one person makes specific modifications, another person will be responsible for recording, and a third person will check and test whether the modified settings are correct. A detailed security policy should ensure that the modification of the hardware firewall configuration is programmed.

And try to avoid errors and security vulnerabilities caused by modifying configurations."

At this point, she paused: "Of course, having a firewall does not mean that we can rest easy. The enemy's technology is also improving, so we need better and more complete network means. Our best

It's good to have a programmer who is dedicated to quick response. When the enemy invades, they can immediately take action... and even invade the opponent's computer."

"It's a pity that we don't have such talents in CIA..." Badua shook his head.

"Maybe we can help you?" Catherine suddenly laughed, "Our telecommunications company has many technicians."

"Sounds really good, but we are going to set up a dedicated response department here. We may need some confidential talents..." Snake said euphemistically.

"oh?"

Catherine did not expect that CIA would suddenly attach such great importance to the Internet.

...Could they be seeking revenge?

It seems very possible.

Although Catherine's financial path has been cut off, fortunately Catherine has already found a way: "It doesn't matter, if your personnel are not skilled enough, our telecommunications company can also provide you with first-class services. We can help you train you to be absolutely professional."
