I just recently made the switch from Windows to Ubuntu, and I'm just a little paranoid when it comes to security measures.
I've looked around and from what I've read, security is not as big a concern as on a Windows OS, but I just want to make sure I'm somewhat covered.
Currently, I have installed ClamTK anti-virus and gufw (and enabled it once).
So basically I have three questions :
- Aside from those apps, updating regularly, and downloading from trusted sources only, should I be taking any other precautions?
- Must I do anything more with gufw other than checking enabled or are the default settings (incoming : deny, outgoing : allow) sufficient?
- Do I have to manually turn on gufw everytime and enable it (and keep it open)? Everytime I open it the enabled checkbox is unchecked.
EDIT: When I open gufw, I must unlock and enter my password, however the checkbox is now checked. Must I always open gufw did I simply need to enable it once?
