Spørgsmål om mystisk log fra E-smith-pakke~
Fra : Nick


Dato : 10-04-06 19:41

Hej alle,

Jeg kører en lille Linuxserver med E-smith-pakken på.

Hver dag får jeg en automatisk genereret statusrapport, og her på det sidste
er der en hel masse som nedenstående.

Er det fordi nogle prøver at logge ind og tester alle mulige passwords af?
Hvordan kan jeg stoppe den trafik? Altså, skal jeg installere noget mere
sikkerhedshalløj?
Jeg roder lidt i blinde, idet jeg fatter meget lidt Linux
Hvis jeg har postet i den forkerte NG må I undskylde.

Tak for enhver hjælp!

/Nick

Folk der tror du kører Windows, enten Windows-maskiner der "leder efter
venner", eller bad guys der forsøger dagens Windows sikkerhedshul. Ikke
noget at være nervøs for, jeg vil foreslå at slå det fra. Det
interessante i en firewall log er alligevel ikke de pakker der
blev blokeret (de kom jo ikke ind), men dem der IKKE blev blokeret.

Dictionary-angreb mod ssh. To forslag:

1. Hvis du ikke har brug for SSH udefra internettet, så bloker for
det i firewall'en eller hosts.allow/deny. Hvis du har brug for det,
men kun fra bestemte ip-ranges, så tillad disse, og bloker resten.

2. Sæt den op til at kræve public key authentication i stedet for
password. Det giver godt nok stadig en masse fyld i log-filen, men
de gætter aldrig en tilfældig 1024-bits (eller mere) key.

Mvh

Jeg kender ikke E-smith, men jeg vil tro det er ét af de systemer der
tvinger dig til at blive dygtig på meget kort tid (fordi mange services
kører, og de skal slås fra, for at forhindre indbrud).

OSSens punkt 9 om servere på nettet beskriver nogle punkter du kan tage
til efterretning:
   http://sikkerhed-faq.dk/servere
Punktet er ikke særligt OS eller teknologi specifik, men det er med
vilje. Hvis du har kommentarer eller spørgsmål omkring punktet, vil jeg
meget gerne besvare dem eller forbedre indholdet af OSSen.

Den første del af statusrapporten fortæller, at et IP filter har stoppet
en masse trafik til din maskine. Uden at vide mere om dit netværk og
dine krav, er det svært for os at sige præcist hvilke dele af trafikken
der bør tillades.

Den anden del fortæller, at et værktøjer via SSH har forsøgt at gætte
adgangskoderne til en masse konti der (i de fleste tilfælde) ikke findes
på dit system. Sørg for at have anstændige adgangskoder på dine konti.
Overvej at bruge SSH nøgler. Hvis du ikke benytter SSH, så sluk servicen.
