<p> Hi everyone! Today I´m going to talk about Sabaton</p>
<h1>What is Sabaton?</h1>
<p>Sabaton is a Swedish power metal band formed in 1999 in the city of Falun.
The group is characterized by its militarized aesthetics and the band´s main lyrical themes are based on war and historical battles.
Even its name comes from the part of the medieval armor that covers the instep of the foot (that in Spanish is called escarpe).
Currently Sabaton has its own festival which is held in autumn and its own cruise-festival which is held in winter</p>

HTML TABLE
Hi again! Here we've made a table using html system and we've written our name, surname and ages inside the brackets. here you can see how it looks:
The structure of the table is the following one:

WIFI SECURITY
-Protocols/version of the WIFI: it's always 802.11 followed by a letter. Ther first one was b, then g, then n and finally, which is the current one; ac. these letters indicate the WIFI's speed.
This is an example of an internet card in which the protocol is indicated:
The aproximatly speed that indicate those letters is:
b: 11 Mbps
g: 54 Mbps
n: 600 Mbps
ac: 1'3 Gbps
Anyway, this speed is not exactly, it can changes but only a little bit.
The name of the WIFI is called SSID (Server Set Identifier). I mean, the names that appear to you in a list for example when you try to connect your smartphone, tabler or computer to a router. Those names are SSID's.
To connect to the Internet through Wifi you need:
- Wireless NIC
- AP
- Router
About wifi security, we must know how to restinct the access to our router using an autentication password and you must also take care with confidentiality, because you don't want other people to know data about yo through ypur router. There are four metods to follow to keep yout security:
1-Open: there must be a password, if there is no autentication, there is no confidentially either.
2-WEP
3-WPA
4-WPA2

CRYPTPGRAPHY
Confidentiality consists of privacy, in this way sniffing is not possible, so data is only visible for people that have the rights to see it.
Cryptography consists of writing words in a different way, and its a way to keep confidentiality.
It is the set of techniques that allows you to encrypt the data.
Encrypt and Decrypt:
Encryption consists of modifying the data using cryptography, so other people can't understand it.
Decryption consists of discovering the way that the data has been encrypt of.
Algorithm: steps or patrons that you can follow to "cifrar" a word or a phrase.
The relation between an algorithm and cryptography is that you use algorithm to carry on cryptography. For example, there are some algorithms that move a letter one place forward or backward, other way to encript something is using numbers instead of letters and then, using algorithms, you mix those numbers and after that, turns them again into words. this way most people wouldn't be ablo to discover the data, but they can find a way to decrypt it too...
A key is the number you use in order to encrypt something using algorithms.
Here I leave you a link to enter in a web that shows a game to encrypt and decrypt data. Using the "cifrado cesar", you use a key (must be a number) and depending of that key you change a letter for another. for example, if you want to change an "a" using key 4, you must write an E, because you must move the "a" in the alphabet as places as the key indicates.

Spoofing is the set of techniques that are used to supplant the identity of a user or server.
News:One boy called Navinder Sarao was placing large sales orders (sometimes hundred of million of dollars in one day)He created a company in the island ‘Levis’.And he manipulate the market in England illegally.
How avoid spoofing?A way to avoid spoofing is enter in secure web pages(https)
FOr example we known that the web page of amazon isn’t have spoof.

Security
Security is the protection you need to defend hardware, software or data on your computer.
You need to protect data, hardware, networks or yourself.
What do I have to protect the data from?
From spoofing, phishhing and malware and backdoors.
What do I have to protect the hardware from?
From hits and balckouts.
What do I have to protect the networks from?
From the people that don't know how use a computer.
What do I have to protect myself from?
From the people that don't know how use a computer.

Password strength:
It´s
important to create different passwords in different accounts to provide
security to yourself.
1.- Think about 5 services you use with a
password.
Instagram, gmail,
twitter, facebook and snapchat
2.- 6
recommendations to create secure password.
Use a long password
Use alphanumeric combinations
Mix capital with
lowercase letters
Interleave keyboard
sings
Don´t put personal
information in it
Don´t use the same password for everything
3.- What
is a password manager? Adventages
and disadvantages.
A password manager is a program that is used to store a large number of user / password pairs.
The database where this information is stored is encrypted using a single key, so the user only has to memorize one key to access to all the others.
Advantages: Allows users to choose complex keys without fear of not being able to remember them later
Disadvantages: We can compromise our security by storing all our passwords
4.- Which were the most common passwords used in 2017?
123
123456789
qwerty
111111
1234567
password
123123
987654321
M1f3ch4d3n4c1m13nt03s29032001 ⇨ 8 Decillion years
⇨ 1 Trillion years
P4s5w0RdDr0Ws5@p
⇨Bu1137Pr0ºF 983 Thousand years
⇨#h#4#$#7#4#G 34 Thousand years
⇨3573Rn0cl31D0M4570iD3o 2 Sextillion years
6.- Two-step verification. What is it?
2-step verification is a method of computer access
that helps you to protect by making it harder for someone to sign in to your
account
Use two different forms of identity: your password and
a contact method
Even if someone discovers your password, they will not be able to log in if they don´t have access to your security information. That's why it's important that you use different passwords for all your accounts.

Create a user account:
1-First search “account”
in the inicio and click on “create standard user account”.
2-Type you account’s
name and click on ”create account”.
3-Click on the account that you´ve just created.
4-Click on create a new password.
5-Just type your new password
6-Now click on logg
off and start your work with the now account that you’ve recently created.
An user profile is a virtual place with a name and usually a
password which you can work from. It´s in computers and there you can save all
your work. It can be administrator (that can change most things of the computer, such as wallpapers) or
standard (which doesn’t have administrator rights)

There are two types of users in Windows: Local users and domain users.
Local users:
Are those which you
can only use in the same machine they’ve been created.
Here you can be a standard user, who has limited rights, for
example it can’t change the IP address.
You also can be an administrator, who is more free at
working with the computer and with the security options.
Domain users:
A group of computers which you can access to from another
computer called Domain Controller. From this one you can allow or deny several
actions to the rest of the group, for instance changing the wallpaper. The password of these users is verified from
the Domain Controller. The disadvantage of this is that if you don’t have
Access to the network, the user’s name cannot be validated, so if this happens
you cannot work.
Every time you finish working from a Domain Controller you
must log off (search on the keyboard “ctrl”, “alt” and “supr” and press them
all at the same time to Access to a panel in which you’ll can log off).
An
IP address is a serie of 4 numbers separate by dots and less than 256 :
300.124.1.2
This is wrong
125.124.1.2
this is good
There
are two different types Public and Private (a router has a private and a public
IP Address)
·
Private:
10.x.x.x 192.168.x.x and
172.16.x.x but the last one is not comun.
·
Public: Every computer has a different one and people
can see yours in the internet.
·
Static: Is manually configured by the ISP(orange, Ono,
Yoigo…)
·
Dynamic: Is automatic
configured
How to change the IP of a computer?
NIC IP Configuration:
1. IP
Address 10.0.72.10
2. Network
Mask: 255.255.255.0 (normalmente suele
ser con tres veces 255, el tercero marca la cantidad de ordenadores que están
conectados)
3. Gateway: “IP of the router”
4. DNS:-Dinamic
-Name -Server Is theIP Address of a machine (Sin DNS no hay
internet, son IPs públicas)
