Firewall is one of the biggest necessecity for a secure device. Ive used UFW [uncomplicated firewall] on Mint and Debian before. Loved it. Did the job, was simple to operate, had GUI and was opensource.
Pretty sure most linux users may have heard about it but if someone is new to UFW, heres a wiki link
I thought i would install it on ParrotSec but before i do anything, I would like to know from the community if this is a good idea. Will it break my machine? because ive heard that installing a firewall on a pentesting OS would not be a good idea. On the same hand, i want my machine to be stealth and hidden in open networks.
All suggestions are welcomed.
