A defensive Raspberry
Nowadays, with the Internet Of Things, more and more computer tools exist and more and more people have access to devices connected to the network. As a result, the number of cyber attacks is increasing, hence the importance of securing one’s network. This is where the idea of Raspberry Onion came from to provide an easy-to-use defensive security solution that includes an intrusion detection system, malicious traffic detection and the ability to capture and analyze network traffic, all on a Raspberry Pi 4 to ensure the security of a home network.
Our solution includes a dozen tools for network security on a Raspberry Pi 4 which are :
-For network security and event alerts: Snort, Barnyard2, PulledPork, Aanval, Maltrail
-For full packet capture and analysis: Wireshark, TCPdump, TrimPCAP, Chaosreader
-For IPS logs: Fail2ban
-For cyber operations. Cyberchef
You can follow the software installations and make the right configurations with the cron and services files. Don't forget to look at the user guide.
