Is Firewall for Dash Masternode even needed ?

The only difference (as far as I know) between Firewalled Masternode and Non-Firewalled MN, is that the Linux kernel will DROP packets in FW case or simply send REJECT ICMP message for non-FW Nodes.

In both cases I have only 2 ports OPEN: TCP/22 (SSH) and TCP/9999 (Dash).

I highly recommend either having ufw or iptables running and have something like DDOS mitigating in front of it.
I would also change your ssh port from say 22 to another port number
and would look at enableing 2fa on your cloud server:

2fa : https://www.vultr.com/docs/how-to-s...sh-on-ubuntu-14-04-using-google-authenticator
changing ssh port: https://uk.godaddy.com/help/changing-the-ssh-port-for-your-linux-server-7306
iptables rules: https://gist.github.com/chaeplin/5dabcef736f599f3bc64bdce7b62b817 - these inlcude rate limiting :)

Enjoy!
