Pi SECURITY
• Change the default username and password. It’s not so much of a deal if you are only using your Raspberry Pi on your local network, but leaving the defaults on an exposed Raspberry Pi is almost like asking to be hacked. Therefore, it is recommended that you change the username and password before opening your Raspberry Pi up to the internet. Be sure to use a very strong password. A good way to protect yourself is by setting up a strong password on your system through the sudo passwd terminal command.
• Keep the operating system updated. An up-to-date operating system is more likely to contain all the necessary patches that will keep your server safe from malicious hackers.
• Make sure that sudo requires a password, since it allows users to perform operations with superuser privileges. By making a password mandatory, you can ensure that hackers are restricted in their ability to inflict damage on your system in the event of an attack.
• Install Fail2ban: this log-parsing application scans for malicious activity in order to prevent DDOS or brute-force attacks on your server.
You can also set up a Cloudflare tunnel on your server to secure the files and pages hosted on it. For a detailed guide on how to secure your Raspberry Pi, be sure to read the official documentation.
