312-38 Exam Dumps : Certified Network Defender (CND)

Michael would view the firewall log to track employee actions on the organization’s network. Firewall logs are records of events that are captured by the firewall. They typically include details about allowed and denied traffic, network connections, and other transactions through the firewall. By analyzing these logs, network administrators can monitor network usage, detect unusual patterns of activity, and identify potential security threats or breaches.

References: The importance of monitoring firewall logs is emphasized in the EC-Council’s Certified Network Defender (C|ND) program. It is part of the network traffic monitoring and analysis, which is crucial for detecting and responding to incidents on the network123.

 A stateful multilayer inspection firewall operates across multiple layers of the OSI model, specifically the Network, Session, and Application layers. It combines the features of packet filtering, circuit-level gateway, and application-level gateway firewalls. This type of firewall inspects the state and context of network traffic, ensuring that all packets are part of a known and valid session. It can make decisions based on the connection state as well as the contents of the traffic, providing a thorough inspection across these layers.

References: The information is consistent with the characteristics of stateful multilayer inspection firewalls as described in various sources, which confirm that they work across the Network, Session, and Application layers of the OSI model1234.

In TCP/IP networking, establishing a connection typically starts with a SYN (synchronize) flag and ends with a FIN (finish) flag. This is part of the normal TCP three-way handshake and connection termination process:

• SYN (Synchronize): Initiates a connection.
• SYN-ACK (Synchronize-Acknowledge): Acknowledges the SYN and responds with a SYN.
• ACK (Acknowledge): Acknowledges the SYN-ACK, establishing the connection.
• FIN (Finish): Terminates the connection.

Observing a SYN flag at the beginning and a FIN flag at the end of the connection indicates a normal, properly terminated TCP session, establishing a baseline for normal traffic patterns.
