[Trisquel-users] Re : Firewall, ssh server... security in general

[lcerf]

With a "personal firewall" (I am not talking about professional usages),  
proprietary software users protect themselves from the programs they  
installed (that can be remotely controlled by their real owners, that can  
send private information to them, etc.) and from those they have not  
willfully installed but that are there anyway (such as Troyan horses). With  
free software, the first issue basically is inexistent (except for Ubuntu's  
spyware): the users control the software. And because crackers do not usually  
attack GNU/Linux (less users, who are not easily duped, who run a great  
variety of applications, who do not run them as root, who have automatic  
security updates, etc.), the second issue essentially is inexistent as well.
