Why must a network administrator consider more security features in addition to firewalls to achieve the best possible network security?
- Experienced firewall specialists may not always be available, requiring the deployment of less complex security technologies.
- Firewalls are expensive to implement, given that there are less expensive security technologies.
- Firewall configuration often takes too much time, and network technicians are more effective if deployed in other security areas.
- Firewalls typically do not stop intrusions from hosts within a network or zone.
