Security tips for digital users

Do we sufficiently protect our information? What should we keep in mind when using open Wi-Fi lines? Do we preserve the security of all the devices (televisions, game consoles, etc.) that we have at home connected to the internet?

Change passwords periodically and do not use it in more than one place. They must have a certain length (more than 8 characters) and contain alphanumeric information (digits, letters and special characters). We must avoid relying on personal information (DNI, names of friends, acquaintances, relatives, pets, etc.) or use very simple patterns (12345).

Make purchases online to suppliers with social prestige consulting previous customer experiences. The websites must be secure (use the https: // protocol) and be linked to recognized electronic payment gateways (such as Visa, MasterCard, PayPal, among others). In turn, you have to keep track of our current account to check the charges of the cards, or even tell the bank to check our account or inform us about certain charges.

Avoid opening emails that do not come to our attention , especially if they include attachments, and flee from all those who are directed directly to us redirect us to pages to correct our personal data or various services- especially banking or administrative.

On mobile is our entire life (social communications, passwords, banking access or services, among others). We must protect well, with words of passage or patterns, undue access to this information. When we are without the device for a long period (for example, loan to third parties or repair in technical service), it is appropriate to restore it to factory values (both software and data). Likewise, we must get used to making backup copies of our device periodically to minimize data loss.

In accessing networks, especially open or shared Wi-Fi lines, we must minimize or avoid any use of services that involve personal identification or access to personal information. If you do not have encryption mechanisms or virtual private networks (VPN), you should avoid using these open networks unless it is a simple navigation without access to personal data.

Protect home networks the modern ADSL + Wi-Fi routers are compatible with different levels of security: it is advisable to change the default passwords of the device and its services, and raise the level of Wi-Fi security (to WPA or WPA2 protocols, for example). In case of unexplained incidents or performance decreases, we must control the devices connected to our network to detect intrusions, as well as change passwords and raise security levels.

Also monitor the security of devices that have recently joined the internet: televisions, game consoles, and real-time playback devices (streaming) of video or audio. In that case, you have to consult the manufacturers and make the necessary updates.

Update the basic software of the computer, mobile phone or tablet, have the latest versions of operating system updates and Office-type packages and general-purpose software such as browsers and their add-ons ( plugins ), file readers in PDF format (for example, Acrobat), Java. In general, all the programs that are of a habitual use, although it is indirect and we are not so conscious of it (readers of PDF files, Java, Flash Player, etc.), must be updated.

Disable unwanted add-ons from browsers. Browsers are often full of search engines or special utilities that, in some cases, collect our browsing data or can simply be ways to introduce viruses or malicious software (malware) into our computer. All the browsers include, in the options, controls for the complements (plugins) installed that allow to uninstall or to disable the doubtful complements. You have to watch because some add-ons are installed as programs and can be difficult to find. Therefore, we will have to uninstall them.

To favor navigation and private searches, it is advisable, among others:

  1. To activate the private modes of browsers;
  2. Ask the main search engines (Google and similar) to erase our data (in Google it can be done through the control panel);
  3. Warn the visited pages that we do not want to be tracked (browsers include Do not track options);
  4. Delete and control the use of cookies in the browser so that our visits or our activity on the websites we have visited are not remembered.
