Impact Analysis Report

[Purushothaman]

Hi there,

I am involved in Adding a Proxy Node to Central Node in QMC.  Before starting, the Client is requesting me to submit the Impact Analysis Report for opening the below ports from Proxy Node to the central node.  The client would like to know the risk status of opening those ports.

Can anyone Please help?

Firewall rules

Source	Destination	Ports	Action
Proxy Node	Central Node	4432	Add
Proxy Node	Central Node	4899	Add
Proxy Node	Central Node	4242	Add
Proxy Node	Central Node	4444	Add
Proxy Node	Central Node	4239	Add
Proxy Node	Central Node	4747	Add
Proxy Node	Central Node	4949	Add
Proxy Node	Central Node	4242, 4900	Add
Proxy Node	Central Node	9028	Add
Proxy Node	Central Node	443	Add

The ports required are listed on the help on a handy Ports page.

It is unclear what kind of assessment you and your client want here, but also it is somewhat concerning that port 443 is being opened between the proxy node and central according to your table, rather than to external traffic, which would let people actually log into the system.

It may be worth reviewing the System Administrator training available from QLik Continuous Classroom
