Bruteforce Attacke seit 36 Stunden...

Also folgendes geht bei mir seit 36 Stunden am Server ab:

so nun bräcuhte ich ein paar Tipps.

Ich habe so eben die neusten Sicherheitsupgrades installiert.

Auf dem Server läuft: Apache2, MySQL, Proftpd (ftp werde ich ausschalten) und Teamspeak2 auch die neuste Version.

Die Angriffe kommen permanent scheinbar über einen Proxy rein.

SSH Port werde ich jetzt auf eine andere zahl legen. Mein Faillog ist 32 kb groß aber komplett leer...

Was kann ich noch tun?

Was hindert dich daran, den Port auf dem der sshd läuft, kurzfristig umzulegen und ggf. PAM für den sshd zu deaktivieren?
 
Eigentlich garnix, habe den Port jetzt auf eine andere Zahl gelegt und neue Passwörter gesetzt.

Zur Sicherheit MySQL und FTP deaktiviert und einen Server restart gemacht.
 
Hi Armin,
solche Angriffe sind zwar nervig aber sind meistens nur Skripts.
Wenn du keine konkreten Angriffe auf deinen Webserver hast oder sowas, und sie nur auf dein SSH Port gehen, sind sie meistens relativ harmlos.
Wirksame Methoden dagegen sind, wie schon genannt, umlegen des SSH-Ports, Fail2Ban und Authentifizierung durch ein Schlüssel statt einem Passwort.
Du kansnt dann noch den Rootuser an der Konsole deaktivieren ( also Rootlogin ) sodass du mit su und / oder sudo arbeitest.
Aber das sind Standardangriffe auf SSH-Server, mit dem fast jeder Server zu kämpfen hat, daher reicht auch meistens umlegen das SSH-Ports schon.
Mit freundlichen Grüßen
Flobbie
 
Du kannst auch einfach in IPTable etwas eintragen, dann ist die IP die du einträgst geblockt und kann garnicht connecten.


iptables -A INPUT -p tcp -s xxx.xxx.xxx.xxx -j REJECT --reject-with tcp-reset
x durch die IP ersetzen.

Für einen UDP ban
iptables -A INPUT -p udp -s xxx.xxx.xxx.xxx -j REJECT
 
Ich habe eine Sammlung von IP-Adressen, die ich bei jeder Neuinstallation defaultmäßig blockiere.

Root-Login per ssh sollte sowieso nicht erlaubt werden (standardmäßig abgeschaltet bei FreeBSD).
