The first thing is to be clear that we are vulnerable, but if we do not learn some computer security techniques, we will be even more so.
1. Avoid clicking on files of people you don't know
It does not matter if in the e-mail they say that they are
from the Tax Agency, El Corte Inglés with a succulent discount, or a wonderful
girl who wants to snuggle with you.
Do not click on files that you have not requested, whoever
has to contact you will do so by other means if it really is important.
2. Do not download files from an unofficial page
It turns out that you have a computer problem and you start
googling how to fix it. You come to a page or a website where someone puts a
link to a page where there is a link to another page where, finally, there is a
program that will solve the problem for you.
But then it turns out that this program is just another
malware that can also end up affecting your PC. Don't trust someone you can't
trust; Leave IT security issues in the hands of professionals.
3. Be careful with your smartphone and your e-mail
Applying IT security measures should always affect all
devices used in the company. A smartphone of today can have free access to
Gmail, where by the way will also be all the emails with passwords of the pages
in which you are registered.
Now imagine that you leave your forgotten phone somewhere
and someone starts using your Gmail account from your email to connect to your
user accounts, your social networks and other private pages. It does not matter
how secure your computer is, or whether you are using antivirus. You must also
protect your smartphone and act with great caution.
4. Set passwords that are difficult to guess
That implies, for example, that you should not put your date
of birth as a password. Not the name of your cat, not your girlfriend, not your
postal address, or anything that someone you know can type from their computer
while trying to connect to your email.
Passwords should be difficult to guess, and preferably
nonsensical. You can use password managers if it is not easy for you to
remember them. By the way, you should put different passwords on each site, not
repeat the same one on all.
5. Set limits on your own computer and in your company
Because if you are a boss and you turn around, but your
computer does not have a password, someone can perfectly connect with user
privileges to different tools or programs that only you control and that
contain information that your employees or your children should not see.
We must be clear that, many times, the biggest breach in
computer security is that we do not foresee situations that could harm us. The
first of the computer security measures has to be to protect us from the most
obvious: that someone enters your computer without permission.
6. Keep your computers updated
When we use computers with non-updated operating systems,
anything can happen to us. Simply because the security patches have not been
installed in that OS and whoever knows of a security flaw in that operating
system can use it against you. And for the record, we warned you.
Working with old systems like Windows XP or even Windows 7
at this point no longer makes sense, when you can perfectly install Windows 10
for free, if you already used Windows before. In our computer maintenance
service we can do it.
7. Use antivirus, or Linux, or Mac ...
You don't have to use antivirus if you don't want to. But,
at least, use an operating system that can give you less difficulties in terms
of computer security. Especially if you are a user who often experiences a lot
of difficulties.
Now, keep in mind that even using Mac or Linux, there are
things that are purely logical and that can end up affecting you, such as
phishing, or anyone who writes to you on social networks, but deep down they
are not who they say they are .
