Ya benar.
Kalau Anda mengaktifkan MD BIS maka perlu tambahkan IP RIM BIS server
kedalam daftar whitelist juga.

DMZ itu memang rawan attack.

In later years we’ve come to rely upon additional intrusion detection
systems such as IPS (Intrusion Prevention Systems) that are focused on
sniffing out (sometimes literally) malicious attacks and attempts to
circumvent security policies and stop them.

One of the core attacks against which such solutions protect services is
a denial of service.

>Unfortunately, it is increasingly reality that the firewall is neither
able to detect or withstand such attacks and ultimately such devices
fail – often at a critical moment. The question then is what to do about
it. The answer may be to simply remove the firewall from the critical
data path for web services./p>
