Security, security, security. This is undoubtedly one of the biggest concerns of any Internet user in the world. It is normal, Nowadays, computers and smartphones have become so essential that we store extremely intimate information in them..
Fortunately, there is a sector that specializes precisely in our security when using any device: cybersecurity. Thanks to it there are firewalls, antivirus and other programs for the protection of your equipment against attacks of any kind.
In this article We are going to talk about the main strategies used by professionals to keep their equipment safeso that you can follow the example to do the same on your computer, be it on a smaller or larger scale.
What is computer security and what is it for?
The cybersecurity or computer security Information security is an area that focuses on the protection of data stored on a computer or flowing through a computer network. This is responsible for guaranteeing 3 fundamental things: the privacy of the data, the encryption of these and above all keeping them out of risk of being damaged.
Data privacy is a matter of life and death in computing, since the information we store on our computer can only be seen by us, and anyone who wants to do so must have our consent. For this it is generally a matter of so that anyone trying to acquire them must decipher them first..
On the other hand, it is important to keep the data away from the reach of viruses or other factors that could damage it, making it no longer possible to read it by any program on the computer. This is very important, since damaged data can cause a chain reaction that affects the operation of softwarean operating system and even the entire computer.
Types of computer security: What are they and what does each one guarantee?
There are several types of computer security, since it has diversified to provide support in everything that has to do with the computer as computer equipment.
Here we tell you what they are and what each one specializes in:
software security
When computers were born, the concept of software security was also born. It could be said that this is the main computer security since it focuses on protecting the programs and the files that make them up. Over the years it has evolved to the point that each software has its own data protection system.thanks to certain internal protocols of this.
hardware security
Over the years, we realized that it wasn’t just the software that needed protection, but the hardware as well. Many people who hear the term think that it strays away from the main idea of cybersecurity.but the reality is that it cannot be more related.
One of the most important terms of digital information security is undoubtedly firewalls or firewalls. These were created to control the flow of data going through the hardware, so that he has to make less effort and has more control over the data he handles to increase his security.
online security
Finally, there is that cybersecurity that is responsible for keeping us protected from the dangers of the internet. It is thanks to this that tools such as antivirus began to be developed, to protect data from malicious files that can damage it, and antispyware to keep those who want to snoop on it at bay.
It is in this where the purest essence of computer security is found, and it is also the one that has received the most study since the term was invented.
What are the main strategies used in digital security and their benefits?
A word that perfectly defines what computer security is is “strategy”. The reality is that this area is based on a set of strategies that reinforce each other to keep a computer or network completely safe in every way.
Here we present what are the Main security strategies that you should take into account and that you can never ignore:
Information backup
One of the most used techniques in the world of information security is undoubtedly its backup. Think wisely. If you are going to keep the evidence of a trial safe, The first thing you should do is back them up in a safe place with a backup. This is precisely what is done with this strategy.
The idea is to simply take the most important data (everyone is) and make a copy of it and save it to a safe place that can be accessed later to recover the data that is needed.
This idea is simple and quite effective, but to be efficient it must have the following characteristics:
- Automatic: a data backup system must be able to be performed continuously automatically every so often. Larger companies need this to be done on a daily basis.
- encryption: to keep the information completely secure after backup it is important that these are encrypted so that no unauthorized third party can access them.
- Remote: it is also vital that the backed up data is stored remotely in a location away from the main computer. Currently, one of the most used is cloud storage.
- Access to old versions: Finally, the user must be able to access previous versions of the backed up information. For example, if you have a document in Excel, it is backed up, then the next day you modify it, and the system makes another copy. The idea is that you can also have access to the version of the backup which was made before it was edited.
These are just some basic features to consider when choosing a backup system. Obviously there are programs that offer certain extras that make them even more secure.
malware protection
A constant threat in the world of computing are viruses or malicious files, which can cause many problems in a database, both for the raw information (videos, photos, audio), and for the data that make up a program or File System.
In this sense, the most important elements to take into account are:
- Antivirus: the antiviruses are programs specially developed to detect malicious files that try to enter our computer, blocking them and sending them directly to a safe location where they do not spread (quarantine), to later eliminate them. They are very complex and are made up of other security elements such as firewalls.
- software control: another thing It is important to have more control over installed programs. If we only have the tools we need on our computer, and not one that we use once every 2,000 years, we will undoubtedly be more protected against threats.
spy protection
Antispyware are those that specialize in preventing a third party, by means of a virus, from having access to the information on our computer, a constant threat especially when we browse the Internet.
To achieve this objective, priority is given to:
- wired networks: old school hackers they used to go near the server buildings and with certain devices connected to the network cabling, intercept its communications. Currently this method is less used, but it is still a threat, so it is important to secure physical communications.
- Wireless networks: in the new school, with the rise of wireless connections, hackers use devices to intercept the signal and obtain the data that flows through itso it is extremely important to ensure this as well.
data cleansing
This cybersecurity strategy is based on the theory that some data is more sensitive than others, which in turn makes it more vulnerable to attacks of all kinds. That is why what is involved in this sense is to clean the system of these files that may represent a risk to the security of others..
In this sense, one of the most related terms is what is known as “secure erase”, which is based on simply eliminating irrelevant data that does not represent a serious loss of information for the company or the system as such.
System monitoring and analysis
Finally, there is the constant analysis of the system to verify that there are no vulnerabilities in it, so a program is necessary to take care of it. This is such an essential strategy, that many programs such as antivirus or antispyware have their own risk analysis and reporting system.
Steps to configure the security of your computer and make it impossible to hack
Although in the previous step we named the different cybersecurity strategies separately, it is important that you know that applying only one of them is not enough. To have a perfectly secured device, it is necessary to apply all of them, or at least most of them.
Based on this, we are going to teach you how to apply several of these strategies on your computer or mobile, to have a first-rate personalized security system. In this way the information of all your devices will be more than insured.
set a password
This is one of the things that computer users ignore, but it is very childish to try to apply cybersecurity to your computer when anyone can access it just by turning it on. Therefore, the first thing you should do is establish a user blockso that every time someone wants to use the equipment, they run into this barrier.
With mobile we are much more aware and almost 100% of users have the screen lock active. This is the first line of defense between prying eyes and your private information.
In this sense, mobile devices have come a long way, offering various ways of unlocking such as:
- PIN: allows you to set a password 4 digit numeric to unlock smartphone screen. It is a very basic concept, like your bank’s debit cards, and therefore it is also the weakest.
- Password: it allows you set a code that can combine numbers, letters, and symbols and have the extension what you wish. It is also a very basic concept, but if you come up with a good password it can be one of the most secure.
- Pattern: It shows you nine points on the screen that you must join following a sequence, without touching a previous point again. Its security is intermediate, since the number of possible pattern combinations is quite limited.
- face unlock: it allows you scan your face to unlock screen. At the time it was an experiment and the sensors were not so reliable, but today they are much more precise.
- Fingerprint: it allows you register your fingerprint to unlock the screen. Current sensors are very accurate and it is by far the…
