Thread: increase network security> personal firewall

    Default increase network security> personal firewall

    hallo folks!

    I want some advice for making my system more secure. I want deactivate any network connection that is unnecessary. Only my browser and the update ability of zypper should have access to the internet. On windows there are personal firewalls.

    How can I block internetaccess for all other programmes on openSUSE?
    Ip tables are complicated!

    So long as you are not running ssh unnecessarily
    What on earth are you worried about
    You can't make comparisons between openSUSE and Windows

    Carl, I guess you misunderstand, imho what he wants to block is OUTgoing traffic (not that I see what the problem behind it is).

    On Windows, it is too easy to load a Trojan. The Windows firewalls are needed to
    block these rogue programs from getting out.

    To the OP: When an OS is properly designed, it is very difficult for this kind
    of program to be installed and operated, thus this type of firewall is not needed.

    Sorry
    I see

    Not sure there is a simple solution to that. I can config my router to restrict a LAN IP to a specific port/s

    isn't this one of the purposes of the whole apparmor thing, to allow
    certain app.s to do stuff online, under certain conditions? i never used
    it, because i also fees safe enough without taking the trouble to
    configure those profiles.

    That explains it. How should I know what Windows does (right or wrong) .

    I don't use Windows, but I have to support several people that do. Whenever I
    answer the phone and hear "Tech support, please", that will be one of those times.

    makes sense in a multi-user environment, of course, where not all users
    are trusted, regarding knowledge or otherwise.
