Need help in system security

[TolanaAudery]

I'm still a newbie in terms of Arch knowledge, and Linux in general.. not that the steep learning curve with Arch makes it any easier...

Either way, in terms of system security, what are some essential apps / precautions one should adhere by? Assuming I have Archlinux installed on my notebook for personal use, and might connect to public wifi networks, connect remotely via SSH, etc...

What I mean is, other than a firewall (not even sure this is essential with Linux), what other security means might be wise to have?
