—Firewall always changing based on organizational
policy and will make a respective person in charge of firewall
take a long time to amend and verify the rule. The rule is
applied to the firewall based on specific parameter. There can
be many ways to create an order of rules, but it will be difficult
and confusing to other person which will have to maintain it.
One of the techniques is to utilize specific parameter as a main
relationship which is traceable and can be expanded with
specific pattern. If the parameter can be combined based on
certain condition and this condition can incorporate in
knowledge based as a library for a set relationship, which at the
end can create a sequence of flow. This relationship will be
recalled if the same condition happens again. In the knowledge
based it also will contain a prediction based on common traffic
which being used frequently. This concept will help and make
easier to manipulate and monitor the rule correctly for multiple
different location but using similar rules. It can be expanded to
compliment other queries which using existing database
firewall to check the queries before be permitted to access
MySql database. In addition, the relationship also covers risk
alert if the combination of low-risk port with medium-risk port
creating a high-risk case.
