Greetings to all the Steemianos, in this opportunity I publish this post that deals with computer security. I title it this way since before we could say that there was the real world and the digital world, but nowadays with the technological advances that have been taking place, we can see that these two (2) have already become one world with many things in common both good and bad, for example, purchases, communication, payment of bills and services, among others to which we were previously limited to physical means, today we can do them through computers, and they are good that has given us the rise of computing in different aspects.

Let's face it, there are many things that we will never be able to do through a computer, which we can do physically, at least not for now, some of these are traveling, eating, hugging our family, among others, but there are certain dangers in the Internet that expose our security and tranquility in the physical world; While it is true that we will not receive a bullet impact from the screen of our computers, it is also very true that the information we have in these, can increase the chances that they will get us somewhere and shoot us wherever we are; it is for them that we must take into account the security issue in our computers.

It is important as users of the Internet, whether in social networks, informative pages or websites where personal and / or financial information is at stake, to maintain a security protocol for such information, since it is not enough to have a state-of-the-art antivirus installed on the computer if for example the user and password of our bank account is written on a piece of paper stuck on the computer monitor. When we handle sensitive data and personal information we must take the same care we have when we go shopping with those we meet on the road, because if we can steal our wallet in an oversight, we can also steal the code of security of the credit card and without need of the delinquent to be present. Friends, there are many dangers on the Web, such as criminals, thieves, sadists, traffickers and much more that use ports in the systems that open and close when you enter or leave information.

Companies for example, in the last 2 years have been victims of information sequestration to which they have had to pay large amounts of money, since the information they handle is of utmost importance for their production systems, but these situations could avoid them just by being cautious when opening emails.

For all the above, my invitation is to be ourselves who make a digital world safer, taking into account that it is also the safety of our loved ones. Develop a good security protocol is important, a good antivirus as long as we know how to use it is a great help, but above all, the most effective is to be always alert, inform us about the safety and dangers of the web, be alert to any situation out of the ordinary and in many cases of those that appear to be regular. Take care of our children and monitor them while they browse, review their visit histories, restrict the use of some pages and other measures that may be convenient for you.

The information I have taken from many sources that I have read during years of studies, which I have not at hand for now, but this has been a personal summary of those articles, there are no textual citations, only the images have the source of where I have obtained them. Remember that this is only a summary, we could start a discussion to deepen more on the subject, you can leave your comments on what they want us to continue discussing.

I say goodbye Waiting for your comments and contributions.

If you think that technology can solve your security problems, then you do not understand the problems and you do not understand technology.
