I know the basics. I'm familiar with the functionality of the OS. I know tails and whonix. The nature of Linux is fairly secure, but I want it better. As far as network security, there are firewalls and intrusion detection systems, but how can I configure it to be as stealthy and encrypted as possible? I'm not really concerned with internet levels security. LUKS isn't good enough for me as far as disk encryption. I just want the most secure thing possible. Multiple layers of encryption, using something stronger than AES-256 or RSA. Both are broken, backdoored or will soon be. I've considered ECC, but I can't hardly grasp it. Any ideas or suggestions?
