- How can we individually test the strength of our password and other authentication devices?
Also, how do "hackers" manage to find these bugs in computer systems?(42 votes)
- With passwords, longer is better. Every added character makes it harder for someone to get into the system. I found an article that may help you more than I can with details. http://www.infoworld.com/article/2655121/security/password-size-does-matter.html(4 votes)
- What is a computer network?(7 votes)
- A computer network is a group of computer systems and other computing hardware devices that are linked together through communication channels to facilitate communication and resource-sharing among a wide range of users.(10 votes)
- so, what are some of the devices most susceptible to hackers and viruses, and why do firewalls work?(3 votes)
- Trams,fridges, etc. All of the things which can talk to the internet but do not need the connection for anything because firewalls are not set up. Fire walls scan or block off suspicious code and make sure that it does not come into the system. That does NOT mean that everything gets filtered, though.(2 votes)
- how can people just guess a password like that...?(3 votes)
- Um, it will take a very long time to crack a password. Like myzack001 said 1111, 1211, they could use a pattern but even then the pattern can be wrong in the first place. Rember a password has letters, numbers, symbols, capital letters so it takes skills to crack a password.(2 votes)
- In Cyber security 101,what do you mean by "that house is the internet"?(2 votes)
- How do people use code to hack ?(2 votes)
- They need the code in order to hack because website are all codes together and so are games and more, which makes is so hacks are created.(3 votes)
- How do you protect yourself from cybersecurity ?(2 votes)
- There is A LOT you can do, but here are some quick suggestions:
1) don't use the same password in to many places
2) use a trustworthy VPN when accessing sketchy websites
3) don't download things from random websites
4) don't answer emails from people you don't know
5) don't share personal information online
6) check URLs and email addresses carefully
7) last but not least, think before you do things and have common sense
If you apply these, you can be reasonably safe on the internet!(3 votes)
- What are the risks, of not getting cybersecurity?(2 votes)
- Without proper security, hackers can easily steal your personal information and use it to their own ends. Most hackers target random victims, so there is a 50/50 chance that your information could get stolen.(1 vote)
- So, they said that the older computers, the giant ones, were supercomputers (0:54). Were they really smarter than the ones we have today?(2 votes)
- why would bases be on the moon and hackers would still get in?

Would you be comfortable living in a house that someone else had the key to? What if an underground tunnel led into it from a public park, or its windows could never quite close all the way? Would you trust it with your safety and your privacy? The internet is that house. This is not to say—never go into the house, but rather, you should know the hazards before you store all of your valuables there—and do what you can to protect them. So why is it insecure, and why can’t we just fortify it until it’s safe? Well, first of all, the internet was not originally built to be what it is today. It’s like someone decided to expand a shoebox into a skyscraper. The internet originally developed when computers were huge and so expensive to own that only universities, big businesses, and a few governments had them. The point, originally, was to let these massive supercomputers talk to each other. And as soon as two computers could send information back and forth, we had a network. The network gradually grew, until personal computers emerged in the 1980s, and then it exploded. Soon people were not just talking to each other, but also exchanging money, playing games, reading news, shopping, and doing everything we associate with the internet today. Other devices started talking to the network too—phones, and cars, and refrigerators, and elevators and power plants, and much much more. But the ease of all of those devices talking to each other came at a price: security. One computer could send another instructions to delete everything on it or take it over—we call these viruses and malware. Or one person could steal another’s identity by guessing, cracking, or extracting a password. Vulnerabilities such as these will never completely go away, because they’re built into the internet’s very architecture. Criminals use them to steal billions of dollars, governments use them for surveillance, and hacktivists use them to further their political goals. Between 2004 and 2013, over 1 billion records of personal information were stolen or leaked through data breaches of major organizations. As a thought experiment, let’s imagine what a perfectly secure internet might look like. Users would not be allowed to download or install anything onto their computers. All internet traffic would be monitored and regulated by bots and humans, massively limiting the number of websites you could visit. In order to log onto a website you’d have to type in a 100 character password, submit a genetic sample, and whistle a tune. The servers that hold data would be kept in heavily armed fortresses... on the moon. And even with all of these safeguards in place, some clever hacker would almost certainly still find a way in. The good news is, even with our flawed internet, there are simple things you can do to protect yourself, and there are a lot of people committed to making the internet more secure. In NOVA’s Cybersecurity Lab, you‘ll play as one of these people, protecting a company that is the target of increasingly sophisticated cyber attacks. You must continuously strengthen your defenses in order to thwart these attackers. You will do this by completing challenges that will give you basic coding abilities, help you spot scams designed to trick you into giving up your secrets, and teach you how passwords are cracked and strengthened. The house that is the internet may be built on a shaky foundation, but it’s been a home to innovation and an unprecedented free exchange of ideas. It’s up to us to make it livable in spite of its flaws.
