Why are computer network is a pile of trash I am writing this to complain about our I.T. network, used daily by staff and students. It certainly makes everything much more easier. But, hackers and cyber-criminals are always discovering new exploits and vulnerabilites in practically everything controlled by a computer, from your phone to your car. Even infastructure, such as traffic lights, power-grids and telephone lines. You may have heard of a new software called "Eternalblue", developed by American hackers and used to leak NSA's digital weapons. And just imagine the fact that our school doesn't have nearly as much security as NSA. Any hacker could comprimise us, regardless of if they want to or not. I have written what I think are the main flaws in the network. Firstly, I must discuss our passwords. Passwords like "Orange876" could be guessed, if given time. Of course, with long and complicated passwords, this is now a memory problem. But, there is a very simple solution to this problem: Give us a physical copy of the password!. You already do this! So why not strengthen the passwords if students can remind themselves of what it is if they forget? I actually did the calculations: a computer could crack the password "Orange876", or any variation of it, in just 4 days. This may seem like a long time, but considering the fact that all our user passwords have the same structure (a noun followed by three numbers), all our user passwords could be cracked in 4 days! Secondly, make the bios password-protected, particularly its features, like the boot order. The bios can be accessed without the use of a password. Also, all computers running Windows 8 and 10 boot from a USB first. Anyone could come along with a USB running a different operating system from windows, and boot from that, potentially giving them access to things they usually cannot access. Password-protect the boot-order, so it always boots from the hard drive. That's at least something. In conclusion, the system may seem strong to an ordinary bystander, but for an experienced, it’s seriously dated and embarrassingly flawed.
