First I want to mark I know that Linux 'doesn't need any antyvirus because there are not viruses for Linux'. But while being surrounded with not-secure websites it's not hard to find programmers which are programming this type of viruses.
I want this topic to be the topic about security and good tips linked with configuration for Linux-begginers.
I've just installed the latest version of Linux Ubuntu. What I've done up to now it was to encrypt the disc with LUKS (TC 7.1a better?), install rkhunter scanner (in order to be sure there's no any rootkit in my system), get the firewall utf (and gutf) and sit on the floor wondering : "What now?". So here you've got a few enquiries - I hope you will help (not only) me : )
1. What is the best free scanner and antyvirus for Linux? (Maybe my rkhunter isn't so good as I thought at first)
2. What do you recommend to change? Imagine you've just installed Ubuntu - what options will you change now? If you can show me your favourite configuration of the system.
3. Are you pleased with dm-crypt or prefer algorithms of TC?
4. Firewall - which firewall and the configuration in order to make the computer very safe
5.Tips for begginers which begginers are not aware of
Thanks for your help!
