Halo teman-teman, Saya baru daftar nih, sebenarnya utk memakai winroute kerio
sudah setahun.Bisa minta pencerahan nih karena belakangan ini sering mendapat
message seperti di bawah ini
Portscan detected
Event description
Host:
202.157.162.247 (202.157.162.247)
Details:
protocol: TCP, source: 202.157.162.247, destination: 10.48.48.139, ports: 1074,
39220, 59731, 1114, 1115, 1119, 48490, 1215, 1257, 45559, ...
Alert description:A portscan is an attempt by an attacker to enumerate the
services running on a machine by probing each port for a response. This is an
attempt by an intruder to determine how best to attack a system. By determining
which services are running on a host, an intruder can direct an attack more
effectively, reducing the amount of time and effort required to gain
unauthorized access. There are many legitimate applications (e.g., FTP) that
can appear to be a portscan. Therefore, you should investigate the initial
events to determine whether they were legitimate or not.

e-mail.Fri Jan 09 10:00:42 2009 Yg menjadi pertanyaan saya: 1. Langkah apa yg
harus saya tempuh utk mengatasi message tsb supaya tidak muncul lagi?2. Apakah
dengan adanya pesan ini artinya Kerio akan menjadi lebih busy sehingga sering
mengalami gangguan koneksi? Sebagai info saya menggunakan Kerio versi 6.5.0
