SECURITY

Today, we learnt a couple of things related to security. For example: what is security, which things do you want to protect, what an UPS is and what Social Engineering is.

a) What is the computer security?

- It is the protection of computer systems from the theft or damage to the hardware, software and many other files.




b) Which things do you want to protect from other people?
- It is really important to protect your data (addresses, credit card, etc...), your hardware, your network and you have to protect yourself too.
For example: if  someone takes/hacks your credit card, that person will be able to use it and spend all your money or if someone gets your WiFi password, that person will use your internet for free.


c) What is the meaning of  UPS?
- UPS (Uninterruptible Power Supply) is an electrical machine that provides emergency power to a load when the main power source fails.



d) What is "Social Engineering"?
- It is the psychological manipulation of people to get confidential information about important data (ex.: accounts' passwords)

*It is also important to always have an antivirus, this way you can avoid malware.

SECURE PASSWORDS

Yesterday, we learnt how to make a stronger password and what a two-step verification was:

First of all, our teacher explained us everything and finally she gave us some questions to answer. These are the questions:

1. Think about 5 services you use with a password:

-Whatsapp, Instagram, Twitter, computers and mobile phones.


2. 6 recommendations to create a secure password: 


-It must have at least 8 characters, it shouldn't contain your name or the name of your company, it mustn't contain your personal information (such as: your ID, your  born date/place, etc...), you can't use words from the dictionary (ex.: sky/cielo), it can't be formed by letters or numbers that are adjacent in the keyboard (ex.: 123456asdfgh) and it must contain characters from each of the following groups: capital letters, lowercase letters, digits or special characters.

3. What is a password manager? Advantages and disadvantages:


A password manager is a software or hardware application that helps a user to store and organize passwords.


-Advantages: it is the best way to make sure you have a strong and unique password for every online account, without  a password manager people tend to have weak passwords and they can be hacked easily, you can aslo store you bank details, passport numbers, credit card, etc...


-Disadvantages: they have a single point of failure (with a password manager you have just one password and if that one password is compromised, everything will be compromised), the Terms & Conditions and, a virus can gain access to whatever is stored on your computer.

4. Which were the most common passwords used in 2017?:


-1234,asdfghjklñ, 12345asdfgh, qwerty, qwertyuiop, etc...


5. Write 5 strong passwords. Check their strength here:


  1) " h3ymynam3sD1ana "--- 609 milliion years.

  2) " wut1sg01ng0nh3r3 "--- 227 million years.
  3) " d0ntudar3t0says0 "--- 6 million years.
  4) " th1s1ss0c00lw0w "--- 175 thousand years.
  5) " 1l1k3ch0c0lat3 "--- 5 thousand years.

6. Two-step verification. What is that?: 


-It protects your accounts by requiring you to provide an additional piece of information after you give your password to get into your account. After entering your password correctly, an online service sends you a text message with a unique string of numbers that you will need to use to get access to your account.


*You can find a two-step verification on your Apple ID, Whatsapp, Gmail, etc...

ABOUT USER PROFILES

A user profile is a collection of settings and information associated with a user. It can be defined as the explicit digital representation of the identity of the user with respect to the operating environment (for example: websites). User profiles contain information such as: the system needs, general data, restrictions and application settings.

It can also help in specifying the terms for certain features in the system (the layout view, color themes, preferred languages, dates, etc...)

WINDOWS' USERS

We've learnt two types of Windows' users: local and domain.


  • LOCAL USER: you can only use them if they are in the machine in which they were created ("alumnoBach" for example). There are two types of local users: Administrator and Standard.


  • DOMAIN USER: One person can control all the computers with just a computer, the domain controller (for example: changing the wallpaper, prohibit access to files, etc...). The Domain user has advantages and disadvantages. One advantage is the fact that you don't need to know the password of each device and a couple of disadvantages of this user are that if the network is down, you can't access to your computer and if you don't log off your domain user session, anyone who uses the computer afterwards can access to your data.
