The security issues that any Linux user should fear

Linux has always been a much more robust, stable and secure operating system than Windows, and one example of this is that most computer threats have always plagued Microsoft’s operating system. However, times change, and Linux has never been infallible, being a sign of it the new threats that, little by little, are endangering the¬†security issues of Linux operating system too.

Although Linux is still a much more secure operating system than Windows, if users are not careful and configure the system correctly they can see their data exposed despite using this system.

Vulnerabilities in Linux Environment

Next, let’s look at the main security issues that any Linux user can encounter.

Dual Boot with Windows and Linux, as allied as enemy

The first problem is likely to be the one that most affects users. A very common configuration among Linux users is to have a dual boot system on the computer that allows you to choose at each boot if you want to use one system or another.

This is very handy, but it also opens the door to various weaknesses for Linux users. Firstly, while you are using Windows it is possible to infect us with malware and, depending on the nature of this, you can even leave useless the hard disk or partition where you have Linux installed.

In addition, the security of Windows OS is much lower than Linux, and it is possible to use special tools to erase the password of the Microsoft operating system, access the system and, from there, use applications to mount EXT4 units Example) in Windows and access all the data.

The way to protect ourselves from this problem is very simple, just do not install the dual boot with Windows to prevent the hard disk from being accessed from it.

However, if for some reason you need to have the dual boot on your computer, the best you can do is encrypt the entire disk of your operating system with applications such as VeraCrypt or LUKS so that, if exposed, the data will not Accessible without your master key.

Malware, increasingly present in Linux

For a long time, hackers have only focused on infecting Windows users who, being more frequent, could have a higher success rate and, therefore, report a greater benefit. However, in recent years this is changing, and hackers are increasingly attacking other operating systems, such as MacOS and, above all, Linux.

Without going any further, in the last 6 months you have talked about two Trojans for this operating system that have caused real havoc in systems using this OS: Rex, Rakos and Fakefile .

The malware for this system, which has long remained inviolable, is increasingly complex. At the moment you can see so much Trojans that look for to collect data like worms that infect computers through the network and complex back doors that can give a pirate of total access to the system.

Within the scope of malware you can not forget ransomware, the worst type of malware seen in the history of computing that encrypts all user data and asks for a rescue for them. In 2015, it was possible to see the first functional ransomware for this operating system, registered as Linux.Encoder.1 and since then, this threat has only grown in this system.

How to protect yourself from malware in this operating system

Currently there are several antiviruses for Linux, some have much more advanced commercial options. However, it is not worth choosing one of them, and is that with basic security measures such as avoiding suspicious files, clicking on links received through the mail and downloading applications from unofficial PPA sources is very difficult for you to finish Infected by malware.

The physical robbery you are all exposed to

Not all threats come from software, but you must also keep in mind that you are always exposed to the physical thefts of your equipment. At any time, especially if you travel with your laptop, it is possible for a person to remove it, thus exposing all your data if you do not have any additional security measures.

How to protect your computer from physical theft

As in the first case, the best way to protect your data from the physical theft of a computer is to have hard disks encrypted . This way, if someone is done with the computer can not access the data without the key, being forced to format the disk and erase your data if what you really want is to use the computer and is not interested in your data.
