    User in the system


    Hi,
    This is more informative then troubleshooting
    I was wondering on how to secure the system and one thing I read about was to avoid having a bunch of user accounts.
    So I typed less /etc/passwd
    and got
    Code:
    root:x:0:0:root:/root:/bin/bash
    daemon:x:1:1:daemon:/usr/sbin:/bin/sh
    bin:x:2:2:bin:/bin:/bin/sh
    sys:x:3:3:sys:/dev:/bin/sh
    sync:x:4:65534:sync:/bin:/bin/sync
    games:x:5:60:games:/usr/games:/bin/sh

    nobody:x:65534:65534:nobody:/nonexistent:/bin/sh

    rtkit:x:111:120:RealtimeKit,,,:/proc:/bin/false
    saned:x:112:121::/home/saned:/bin/false
    hplip:x:113:7:HPLIP system user,,,:/var/run/hplip:/bin/false
    mijk:x:1000:1000:Mijk,,,:/home/karl:/bin/bash
    pira:x:1001:1001:Pira,1,,:/home/pirata:/bin/bash
    the users I use are those 2 last.
    My question is: is there anything I can do on the other rest to secure my system?

    Thanks for your patience

    That depends on what you mean by "secure" the system. If your only concern is to prevent other users from altering or deleting your files, it should be a simple process of setting the permissions so other users only have read privileges. If however, you do not even want others to be able to access your files, I do not know. Perhaps it is possible to set the permissions to not allow viewing?

    Then there is the option of encrypting files, which I know nothing about, but there is probably helpful information in the Debian wiki.
