Security is a very important factor and it must always be present when using connected devices and systems on the network. There are many attacks that we can suffer and many techniques that hackers use to achieve their goal. In this article we are going to see how they can access our system . What a cybercriminal could do or what would be based to access our information.
How could they enter our system
As we have indicated, hackers have multiple ways to access a computer, to send malware , to steal our information. It is true that the security tools that we have at our disposal have improved a lot in recent years, but so do the techniques that attackers use.
There are some aspects that are key for cyber criminals. We can say that they take advantage of mistakes we make, of problems with our equipment, of certain vulnerabilities in order to achieve their goal. This means that we must always take precautions and not compromise our security and privacy.
Not having updated systems
Without a doubt one of the most important issues, one of the problems on which attackers rely most is when a user does not have the systems updated correctly. There are many occasions in which security flaws arise, vulnerabilities in computers, and that can be exploited to enter the system.
It is the developers themselves who release patches and updates to correct those vulnerabilities. It is very important that we always have the most current versions installed and thus avoid problems. It is one of the barriers that we can use to prevent intruders from entering our systems.
Have basic encryption or weak passwords
Of course they can be based on weak passwords and inappropriate encryption. This is something that can happen with our wireless network, for example. Also in any account or system that we are using.
It is very important to always have strong and complex passwords. They must contain letters (upper and lower case), numbers and other special symbols. All this in a random way, having an adequate length and also not using it anywhere else. It is undoubtedly one of the most important questions.
Sharing sensitive information
But they can also be based on mistakes that we have made on the Internet. An example is sharing sensitive information that we shouldn’t. Maybe we have posted on a website or forum and left our email. They could later send us an email with an attachment that when downloaded serves as a gateway to our team.
It is vital that we always keep our personal information safe. We should not show more than is necessary and never use tools that are not safe. Any data we make public can be used by anyone against us.
Don’t use two-step verification
Another major mistake by users is not to use two-step verification when available. This could prevent intruders from entering our systems and accounts. As we know it is an extra security barrier, a second step that they must complete if they want to enter our account even with the password.
More and more services have this option. Whenever possible we should activate verification in two steps. Otherwise they could access our systems if they manage to break the password.
Malware
But if there is something that cyber criminals use a lot to enter our systems, it is malware . There are many varieties of malicious software that can compromise our security and personal information. Many types of attacks that in one way or another can compromise us.
The goal here is to not allow malware to enter our systems. We must make use of security tools that protect us, but also of common sense. Many types of malware can enter through email. They may require user interaction, such as downloading or executing a malicious file. We must always keep common sense in mind and not make mistakes.
