Compare the concept of defense-in-depth and the principle of least privilege.
What will be an ideal response?
In connection to firewalls, the defense-in-depth concept mandates that a single firewall should not be your only defense. Deploy a sound network firewall architecture, deploy host-based firewalls, and use IPS and other security technologies to ensure that if a firewall is breached, the attacker is stopped elsewhere. The principle of least privilege mandates that users be given the minimum amount of privilege to do their jobs. With firewalls, this principle translates into starting with default firewall rules that deny all traffic and then gradually allowing more traffic as the business needs dictate.
