Modifying a firewall configuration
When you modify a firewall configuration, it is important to consider potential security risks to avoid future issues. For this discussion, assume the role of a network security administrator tasked with installing a specific firewall on the network. Select one of the following firewall types:
Software
Hardware
Cloud
Packet filtering
Stateful inspection
Multilayer inspection
For your main post, identify your firewall choice and provide a summary of the functions it will provide the network. Conclude your post with your assessment on the necessity of the firewall in protecting the network.
Sample Answer
Firewall Choice: Stateful Inspection Firewall
Functions of a Stateful Inspection Firewall:
- Packet filtering: Stateful inspection firewalls can filter packets based on a variety of criteria, such as IP address, port number, and protocol. This helps to prevent unauthorized access to the network.
- Stateful inspection: Stateful inspection firewalls track the state of network sessions and use this information to make filtering decisions. This helps to prevent attacks that exploit vulnerabilities in specific protocols or applications.
- Application inspection: Stateful inspection firewalls can inspect the contents of packets to identify and block malicious traffic. This can help to prevent attacks such as viruses, worms, and denial-of-service attacks.
