Grüß Gott zusammen!

Ich habe ja so ziemlich alles gemacht, was mir empfohlen wurde, in Sachen Absicherung. Es scheint auch wohl alles gut zu sein.

Aber manchmal kriege ich einen richtigen Herzkasper, wenn ich in die Logs schaue...

Ich weiss zwar, warum diese Meldungen kommen, vor allem die letzten, aber ist es wirklich "ratsam" alles zu ignorieren? Passiert iss ja nix im Prinzip, ausser dass jemand "Blödsinn" mit der DNS treibt...

Bitte beruhigt mich ein wenig, oder gibt es noch einen Tipp für mich?
Oder
