Keeping software updated is one of the most important pillars of digital security. Operating systems, antivirus software and applications should be updated regularly, as manufacturers are constantly patching identified vulnerabilities. Cybercriminals are constantly on the lookout for vulnerabilities, and as many as 60% of data leaks are the result of outdated systems. It’s worth enabling automatic updates that run in the background and don’t require our attention.
It is also recommended to review the list of installed applications and eliminate those you no longer use. The fewer unnecessary programs, the lower the risk of a security breach. Let’s pay attention to the extent of the data that applications have access to:
- whether a calculator app really needs access to contacts,
- whether a simple game requires location,
- whether a photo editor should track our text messages.
Limiting app permissions helps protect our privacy and personal data.
Regularly checking online accounts is another key step. Every so often, it’s a good idea to:
- check what devices we are logged on,
- review login history for unusual activity,
- log out of suspicious places,
- delete old, unused accounts,
- change passwords for key services.
Keeping files and documents organized is also important. It’s a good idea to keep important data organized and back it up regularly. Deleting unnecessary files makes it easier to manage information and reduces the risk of accidental loss.
In daily use of the Internet, caution is extremely important. Let’s only click on links from reliable sources. Before opening a file or message, let’s stop and think about who sent it. As many as 91% of attacks start with an email, so vigilance is an absolute must.
Using social media safely requires limiting the information we share with others. Avoid publishing:
- your exact home address,
- information about planned trips,
- tickets, boarding passes, documents or identity information,
- photos containing sensitive data,
- real-time locations.
Regularly checking your privacy settings is the basis for protecting your own data.
Strong and unique passwords are the foundation of cyber security. For the most important accounts, it is a good idea to use:
- combinations of letters, numbers and special characters,
- a different password for each service,
- a password manager to store them,
- two-factor authentication (2FA),
- regular changes – at least every few months.
81% of account hacks are due to weak or repeatedly used passwords.
Unplugging is also important for our digital health. From time to time, it’s a good idea to:
- turn off Wi-Fi, Bluetooth and location,
- consciously log off from devices,
- limit online interactions,
- take care of the digital balance between work and rest,
- spend more offline time with loved ones.
This not only allows us to relax, but also reduces our digital presence and the number of potential points of attack.
Knowledge is the most effective shield against online threats. It is worth:
- follow information about the latest threats,
- learn to recognize fraud attempts,
- share knowledge with family and friends,
- participate in cyber security training,
- use reliable sources of information.
As many as 95% of cyber incidents are due to human error, not technical failure.
The principle of limited trust should be our guide. Before we accept something as true – let’s check it with several sources. Before installing an application, it’s a good idea to read user reviews, and treat any message – even one that looks official – with caution. This attitude can avoid up to 75% of risks.
Digital hygiene is not an elaborate process – it is a daily, conscious choice and habits that together effectively protect us in the digital world.
