Cyberattacks are a global problem that costs the world billions of dollars a year in the form of stolen data, drained accounts and damages. According to this report by the World Economic Forum, cybercrime is already more dangerous to humanity than environmental disasters and infectious diseases.
However, little is said about protection against hackers, and even less is understood. This is especially true for individual users who do not know how to protect themselves on the Internet.
The truth is that protection against computer crime does not have to be complicated and expensive. There are a few simple things that any user can do to reduce the risk of hacker attacks. None of them will guarantee you 100% safety. But it will give you some level of information security.
Use hard-to-guess passwords
Passwords are the main (often the only) key to your digital identity. We use passwords to lock our online communication, social media accounts, bank accounts, financial assets, memories and much more.
The worst thing you can do: use easy passwords like 123456, write them down everywhere and don't change them.
What to do: Choose a hard-to-guess password that (at least at the current level of technology) can't be cracked. Do not use one password for more than one account. Don't write down your passwords on flyers or in your laptop's browser.
Update your software
More than 50% of the world's software is not upgraded, according to a study. This is a problem because older versions of software products may have vulnerabilities that hackers attack. The same vulnerabilities have been fixed in the new versions.
For example, did you know that if you're still using Windows XP, you're at risk for over 200 critical vulnerabilities? They are very well known to hackers and you can't plug them because this operating system is no longer supported.
You need to regularly update both the operating system and the main programs you work with: browsers, office suite, players, messengers, etc.
Avoid public Wi-Fi networks
Yes, I know that you do not spend on mobile internet, and the Wi-Fi connection will probably pull more than that of the smartphone. But open wireless networks are dangerous. They may be compromised. They can track what you browse, what passwords you enter and what messages you send. It can happen, although most sites already use HTTPS encryption.
