Bør jeg være nervøs for disse port scans?
Hejsa,Vores firmas kontor er beskyttet af en firewall (Zyxell Zywall 5), og de sidste to dage har den tidligt om morgenen nulstillet sig selv fuldstændigt. Den et firewall/router for os. Jeg har nu opgraderet f/w, og har backup af settings - håber lidt det hjælper på nulstillingen (hvis ikke den er defekt).
Anyways, i loggen på firewallen kommer hele tiden en masse requests på nogle høje portnumre, som bliver "droppede" da der ikke er åbnet for disse.
Jeg har ikke tidligere bemærket dem, så ved ikke om de er kommet eller overhovedet har noget med nulstilling/nedbruddet at gøre.
Er det nogle jeg bør være nervøse for?
