My name is Brayden Miller and I am a student in Cybersecurity at MIT. I'm so happy to be speaking to you guys in France today. I hope that everyone at the Lycée de la Cotière is having a good day. 

So, let's talk about Cyber Security. 

Cybersecurity is the protection of computers, networks, and data from attacks. It means building systems that are safe, and stopping hackers from stealing information. Today, almost everything is online: banking, shopping, health records, even schoolwork. This is why cybersecurity is so important — it keeps our digital life safe.

But, let's be honest : Cybersecurity has many challenges. 

Hackers are getting smarter every year. Companies and governments must spend a lot of money to keep systems secure. We also need laws to protect privacy, but sometimes those laws are not the same in every country. Another problem is that people often use weak passwords or share personal data too easily, which makes attacks easier. If we do not work on these issues, society can lose trust in technology.

For me, cybersecurity is exciting but also stressful. I feel proud when I solve a problem or stop an attack in a simulation. But sometimes I feel worried about the future, because attacks are growing and can affect hospitals or power plants. I believe everyone should learn the basics of cybersecurity. It is not just a job for experts — it is something that protects all of us. And it is something we should all be thinking about and working on. Not just the experts. 

Have a good day, guys. And say 'Hi' to Mister Kirrage.

Speaker 1

With the assistance of the outside broadcast unit, we will be linking from the Database studio to their home. Pat Green and Julian, welcome to Database. 

Speaker 2

Hello, Jane. 

Speaker 3

Hello, Jane. 

Speaker 1

Now, Julian, I see you have your computer linked to the telephone line. Can you tell us how you did that? 

Speaker 3

Yes. Well, it's very simple really. Um, the telephone is connected to- 

Speaker 2

(clicks tongue) 

Speaker 3

... the telephone network with a British Telecom plug, and I simply remove the telephone jack from the telecom socket and plug it into this box here, the modem. I then take another wire from the modem and plug it in where the telephone was. I can then switch on the modem, and we're ready to go. (computer click) Um, the computer's asking me if I want to log on, and it's now telling me to phone up the main Prestel computer, which I will now do. Um ... (dial tone) 

Speaker 1

So it's a very simple connection to make. 

Speaker 3

Extremely simple, um, and I can actually leave the modem plu- plugged in once it's done that without affecting the telephone. I'm now waiting for the computer to answer me. It asks for the tone, and then I just flick a switch on the modem and replace the receiver. And ... 

Speaker 1

Things are starting to happen. 

Speaker 3

Things are starting to happen. The Prestel computer is now asking me to enter my own personal password, (computer beeps) which I have now done, and it comes up with an op- an opening screen. (computer beeps) 

Speaker 1

Now, Julian, can you tell me, what is Micronet? 

Speaker 3

Well, Micronet basically is an area od- of Prestel that's specially designed for microcomputer users. It has a lot of facilities, uh, has a magazine-type page of what's new today, the daily news, reviews of the current software that's available. There's a letters page so people can write in. Um, there are programs available on Micronet th- you can load directly down the phone line. Some of them are free. Some of them, you do have to pay for. 

Speaker 1

Now, Pat, whose computer is it? 

Speaker 2

Well, it's a cooperative really. We all have a s- part share, but Julian la- and I mainly use it. 

Speaker 1

And why did you buy a computer? 

Speaker 2

Well, I was very interested in the new technology and didn't want to be left behind. I don't think it's only for the youngsters at school now. I think us older ones will have to learn a lot about it. 

Speaker 1

And what do you use the computer for? 

Speaker 2

Well, for keeping household records such as, uh, what I have in the freezer and people's telephone numbers and addresses. Um, I use it as a word processor for my letters, which always come out perfect now. 

Speaker 1

(laughs) 

Speaker 2

And, um, the most exciting thing, I, I find is, um, the mailbox s- uh, where I s- I write to other people on the Prestel system. 

Speaker 1

And who have you written to recently? Have you got any examples? 

Speaker 2

Um, yes. Um, I sent a message to my doctor asking for a repeat prescription, and, um, he said he's left the prescription for me in the chemist. 

Speaker 1

Right. Well, thank you very much, Pat and Julian. We'll be seeing you later in the program. 

Speaker 2

Bye, Jane. 

Speaker 3

Bye, Jane. 

Speaker 1

If, if you have anything you want to say to us here on Database and you're connected to the Prestel service, you can use the Database mailbox. Pat Green is still with us in North London, and she's gonna demonstrate this facility by sending us a message. Hello, Pat. 

Speaker 2

Hello, Jane. 

Speaker 1

Can you find page 7776, please? (computer clicks and beeps) And now would you like to send us a message? 

Speaker 2

Yes, I will. (computer click) 

Speaker 1

And I should be able to get the same message now on my screen. 

Speaker 2

That's right. (computer beeps) 

Speaker 1

Thank you very much for your good wishes, Pat and Julian. 

Speaker 2

You're welcome. 

Speaker 3

You're welcome. 

Speaker 1

If I want to get that message printed out, I can do that as well just by hitting this button. (computer whirs and clicks) And there it is. 

And by the way, we've heard some rumors that Commodore are planning to launch their own rival to Micronet, which will come complete with a modem. Now, as we get some more news about Compunet, we'll let you have it. In the meantime, if you want more information about Prestel or Micronet, then why not have a look at the Database newsletter, which you can find on Oracle page 182. That's page 182. 

Now, if you own a BBC Micro, stand by for the software transmission. You can record the data directly from the audio track of your video cassette recording of Database. Alternatively, if your television has an audio jack or an ear socket, you can take the data directly from that. The least successful method is to just place a microphone in front of the television set. 

Now, if you haven't got a BBC Micro, don't worry, because during the series, we'll be transmitting data for the ZX81, the Spectrum, the Commodore 64, the VIC-20, and the Dragon. Now remember, these software transmissions are experimental, but if they're successful and you like them, then they may well become a regular feature of Database later on in the year. 

Stand by for the software transmission. You better start your recorders now. Goodbye, and see you next week from Earls Court. (high pitched tone) (static) (high pitched tone) (static) (high pitched tone) (static) (high pitched tone) (static) (high pitched tone) (static)
