The best tips and tricks to improve your security and privacy on the Internet

Security and privacy on the Internet

La Internet security and privacy have become topics of great importance, especially at this time, where cyberattacks are the order of the day. Browsing the web, conducting online transactions, and sharing personal information have left users exposed and totally vulnerable.

For this reason, in this article I will show some Tricks and tips that you can carry out in your Ubuntu distro to improve these two aspects that should not take them away just like that.

Risks of not protecting yourself

cyberattacks, security and privacy

Some think that to use the Internet all you have to do is use a fiber, mobile and TV comparator to look for a cheap, stable and fast rate, and once they have access to the network, start browsing, without taking any precautionary measures. And yes, it is important to have a good ISP, but forget about your security and privacy can lead to serious problems of the caliber of for example:

Did you know that the average losses per user in cases of bank robberies amounts to around €12000 and business robberies can be over a million?
  1. Identity Theft: Criminals can steal personal information to impersonate a user and commit fraud under “your name,” which could lead to serious legal problems for the user.
  2. Phishing- Scammers can trick users into providing sensitive information such as passwords and credit card numbers, thereby committing money theft, among others.
  3. Malware: Although Ubuntu, or GNU/Linux in general, does not have as much malware as in the Windows world, we must not forget that it exists. Therefore, becoming infected with this type of malicious code could lead to the loss of information (ransomware), data theft, etc.
  4. Privacy violation- Personal information may be shared or sold to third parties without the user's consent. Sometimes to track your habits and preferences to show personalized ads, but other times it can be for other, more concerning purposes. For example, if they have managed to access private data or multimedia content, they could also use it for blackmail.

And this is especially worrying when you are not only a private user, but you use your Ubuntu computer to telework or your company has a BYOD policy, since in this case it is not only your data, but also that of the company or customers. This is why it is vital to protect your security and privacy on the network as much as possible.

Tricks to protect your security and privacy

safety tips

Once you know the risks you face, the next thing is put measures to protect your security and privacy. You can never trust yourself 100%, but at least you can avoid many evils or reduce their impact to a minimum. And for this, the most relevant tips and tricks are:


A VPN (Virtual Private Network) It is an essential tool to protect your security and improve online security. And it not only camouflages your IP, but also encrypts the Internet connection, therefore, all the connection data will not be accessible as easily by third parties, such as cyber attackers with network sniffers, ISP providers that store all your activity, etc. To choose the appropriate one in your case, you can enter this website that we have dedicated to it.

This can be of great help if you access tax or banking services, if you work remotely and are an administrator of a remote server that you access via SSH, etc.

Tor Browser + DuckDuckGo

Having a VPN is not a guarantee of total protection, although it is a very important step when it comes to protecting your security and privacy. However, for a little further, I would also recommend using an extra layer to browse completely anonymously and that your privacy is exceptional with Tor Browser and the search engine DuckDuckGo, much less invasive than Google and other well-known search engines.

Tor Browser is a web browser that allows you to access the Internet completely anonymously, it works by redirecting your traffic through a network of volunteer servers around the world, making it difficult to track your online activity. And although it could previously be used as a sole method of camouflage, this is not currently the case, and there may be nodes on this network that are not secure enough. That is why it is vital to also have the VPN active.

On the other hand, DuckDuckGo, is a search engine that respects your privacy. It's pretty good, and its interface is very similar to Google. But unlike other search engines, DuckDuckGo doesn't track your searches or sell your data to advertisers.

Tricks and tips

With this, we would already have a huge part done to guarantee our security and privacy, but now we are going to see some extra tips which are also important, and that you have probably seen numerous times but, although it may seem strange, there are still many users who continue to ignore it:

Strong passwords

In order to have strong and secure passwords, and make life difficult for cyber attackers if you want to access your services, the most important thing is to follow these tips:

  • Length- Your password must be at least 8 characters, although ideally 12 or more.
  • Complexity- Includes a combination of uppercase, lowercase, numbers, and symbols. Do not use words that are in the dictionary or personal information, as it is susceptible to dictionary attacks or social engineering.
  • Avoid master passwords- Do not use the same password for multiple accounts. If they can find out, they will have access to everything. While if each service has a different one, they will only have access to the one that has been exposed.
  • Change your passwords regularly: It is good practice to change your passwords from time to time. You already know that in Linux you have tools to make passwords expire and force the user to change them.
  • Use a password manager: Password managers can generate and remember strong passwords for you. For example, KeePass is an app available for Linux and very secure that I recommend.

Isolate your banking or sensitive data

It is important to keep your banking details and other sensitive data separate from your other online activities. To do this, you have the following recommendations:

  • If you use your online banking service, do not store passwords in your web browser.
  • Do not save your credit card number on your PC, nor photos of it, ID scans, and other personal or tax data. If you have them, it is better to store them on a pendrive, and if it is encrypted, much better.
  • Many people may have photos or videos of an intimate nature. These should not be stored on the connected PC either, better on a device without Internet access. And much less in the cloud, you already know what happened with the famous Celebgate case in which intimate material of many celebrities was stolen in iCloud.
  • Do not post sensitive information on social networks or share it with strangers.


Keep your updated devices and software. Updates often include security patches that protect against the latest threats. Thanks to them, many vulnerabilities can be corrected that can no longer be exploited by third parties.

This not only involves updating the applications and the operating system, it is also important do it with the firmware (from the CPU microcode to the firmware of your router, etc.), since this could also have vulnerabilities.

Secure sources

Always trust the secure sources, and not in other sources:

  • Only download your Ubuntu distro from the official website, and do not trust other sources that offer the ISO, as it could be manipulated and contain malicious code.
  • On the other hand, do the same with applications, always download from the developer's official website or from the app store of your distro or from the official repositories. This is even more important when it comes to controllers or drivers, and firmware, since it is code that will be executed in privileged mode and the disaster could be greater...

Become suspicious!

Finally, the best way to protect yourself online is be skeptical, distrustful, almost paranoid:

  • Do not trust emails, SMS, phone calls or messages through instant messaging apps asking for passwords or personal information. The banks, companies with which you have services, etc., will never ask you that, so if they are doing it, it is someone malicious posing as them.
  • If you see a suspicious site, do not transfer data on it or do any type of operation.
  • Ignore the pop-up ads that appear on many sites telling you that you are infected or asking for your information.
  • If you see a really surprising offer, be wary of it. Through social networks and other media, there are advertisements for very cheap products that only seek to get a user to enter their payment information and thus be able to steal their money. Once payment is made, these products will never reach you. They can even be from supposedly official stores, since they clone the sites and apparently you are on the official website (look at their URL and check if there is anything suspicious).

I hope I've helped! With these simple tips and tricks, you will not have to suffer many misfortunes while browsing and enjoying cloud content on your Ubuntu…
