I am using Ubuntu 14.04 desktop. I want to block certain applications from accessing internet and allow some. Can this be done using UFW ? If yes, how ? If no, can it be done by any other method ? I do not want to use GUFW. I am able to block by IP but not by applications.

( year 2018 ) Not possible.

Exists only artificial dentures which only can allow or block port from /etc/ufw/applications.d/ or from /etc/services. Similar problem exist with iptables. However iptables also have or had "-m owner --gid-owner" module. https://unix.stackexchange.com/questions/373703/unable-to-get-iptables-owner-module-gid-owner-to-work#373783
