You are a Network Security Engineer in a tech startup. You are asked to write
firewalls for the company systems to block all connections except the ones
that company approves, so that you can prevent your company employees
from accessing them and to improve security.
Instructions:
• Don’t change any of the existing policy for any of the Chains
• Consider all Input packets are DROPPED by default and follow the
instruction
• Only accept connections from the Ip 8.8.8.8 and 8.8.4.4 from the INPUT
chain
• Allow ping in and out of the machine
• We don’t want any insecure connection to be established, so drop all
output packets from the http port with icmp message
NOTE:
Once you have written all the firewalls, make sure that you are saving your
firewall configurations by running $sudo sh save.sh before submitting, which
is present inside ~/Desktop/Project/ wings-t7-curriculumhandsonnetworksecurity
