Analyse

Na drie dagen 399 sshd aanvallen geregistreerd. Reden om hier een ander poort nummer voor in te stellen. Port 22 is blijkbaar erg geliefd onder hackers. Opvallend, United States met 94 op nummer één en China met 86 op nummer twee maken samen bijna de helft van de aanvallen uit. Rusland komt op de 8st plaats met 14 aanvallen.

Apache en Dovecot aanvallen werden "slechts" 16 respectievelijk 9 keer geregistreerd in deze periode.
