Πρέπει να αγοράσεις protection ή κάποιο καλό firewall.

 

Καλύτερα θα ήταν να βάλεις τον σέρβερ σε μία εταιρεία που να έχει protection

τα ddos δεν είναι όπως λέμε φέρε μου το fix για το "noobish error"

Τα ddos είναι άλλη υπόθεση,γιατί πολύ απλά δεν κάνουνε αττάκ στον σέρβερ αλλά κάνουνε στο deticated,και συνεπώς άμα το attack είναι μεγάλο πέφτει ο σέρβερ.

Τώρα,πιθανές λύσεις για αυτό

Είναι να πληρώσεις για ένα καλό firewall ή να βρείς κάποια εταιρεία hosting που να σου προσφέρει firewall , συνήθως με datancer στην αμερική , ή κάποια cisco router που κοστίζει.

DDOS attack exoume otan floodarei apo polla compromised PC to sigekrimeno simeio sto monopati.
