Περι security

[imported_Dimitris]

Είναι ένα site <A HREF="http://www.grc.com" TARGET=_blank>www.grc.com</A> το οποίο σου κάνει εικονική επίθεση για να βεβαιωθείς ότι το σύστημά σου είναι απαραβίαστο.<BR>Μου φάνηκε λίγο φόλα γιατί ξεκίνησε τις επιθέσεις και μετά μου είπε <<Μπράβο. Το σύστημά σας είναι απαραβίαστο. Ελάτε μετά απο μία εβδομάδα όμως γιατί θα έχουν εξελιχθεί νέες τεχνικές για να διαπιστώσετε ότι το σύστημά σας παραμένει ακλόνητο>>.<BR>Καλά με κοροιδεύει ;<BR>Όποιος το έχει δοκιμάσει ας πει την γνώμη του.<P>Υ.Γ. Το μόνο που έχω είναι το blackice<BR>

Το έχω δοκιμάσει και εγώ. Δεν νομίζω ότι είναι κάτι πονηρό. Ισα-ίσα που έχει κάποιες καλές οδηγίες για να κλείσεις ορισμένες τρύπες που πιθανόν έχεις.Εξάλου κάπου είδα ότι συνεργάζεται και με το zdnet (κάπου το αναφέρει στο site του) οπότε και μόνο αυτό αρκεί για να σε πείσει ότι δεν συμβαίνει κάτι πονηρό...<BR>και πριν κανά 3-4 μήνες κάτι έλεγε το ram για αυτό το site οπότε δεν το νομίζω..
