Viele Brutes
Hallo,
habe seit kurzem ein Vserver bei 1blu und wollte mal wissen ob ich mir zwecks Sicherheit mehr Gedanken machen sollte, habe bisher in dem Punkt auch noch nicht viel gemacht, weil ich acuh garnicht weiss wo ich da am besten anfange. Ist es normal innerhalb von 7 Tagen Betrieb bereits 3 mal intensiv gescannt worden zu sein? Find das schon ein bisschen krass, zum Glück hatte keiner Erfolg. Hier mal ein kleiner Auszug daraus, auf welchen Einträgen ich noch nicht klar komme sind die ganz unten, dick markiert, klärt mich bitte auf was das zu sagen hat, vielen Dank.
Mfg MajorP
Was mich ausserdem noch interssiert ob die Dienste alle unter sicherheitsspezifischen Aspekten richtig laufen, grade der Emaildienst macht mir da Bedenken...
