Even by using the most secure wallets, you are always vulnerable online. By securing your network, you will drastically decrease the risks of being attacked.
What you should never do is to connect on a public network and have a look at your investments. The public network is already too risky even for having a look at your emails, do not even think about connecting yourself on any exchange.
When being connected to your home network, the only measure most people use to protect themselves is to set up a password on your wifi. However, this security is weak, and any amateur exploiter may enter.
For this reason, learning how to secure your home network is essential.
First, change the name of your default home network. It will make it harder for any cybercriminal to know what type of router you have.
Then, make sure you set a unique and robust password. The default password is easy to guess by hackers, especially if they know the router. An excellent wireless password should be at least 20 characters long, including numbers and letters.
What you should do next is activating network encryption. However, you should avoid WPA2, which had vulnerability issues in the past. Prefer the WPA3.
When you are not at home, you should turn the home network off.
Finally, to increase your security, you can purchase a hardware firewall that should protect your network.
Once your private network is secure, the first thing you should do is find a reliable VPN (Virtual Private Network) service. The VPN will be hiding your I.P. address (and so your location) and establish secure and encrypted connections to provide greater privacy.
You should now consider purchasing a reliable Antivirus service, use this list for the best recommendations. This antivirus should be updated, the best to do is to set the updates to automatic. As per the antivirus, the O.S. (operating system) of your computer should always be kept up to date.
This will prevent from vulnerability and enhance your security. When navigating on any website, double-check the links to avoid phishing attacks.
When a website is breached, the site often shows a certificate error, and do not display the https security mark. Never submit any information to this kind of website.
