 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.

A mesh network topology is characterized by each node (computer or device) being interconnected with every other node in the network. This allows for direct data transmission and multiple pathways for the data to route itself, enhancing reliability and robustness. In a mesh topology, the absence of a central hub means that the network can dynamically reroute data if any node fails, maintaining the network’s overall connectivity.

References: This description is consistent with the core features of mesh networks as described in the Network Defender (CND) study materials and further explained in various educational resources on computer networks1234.

Indicators of attack (IoA) provide information about the attacker's intent, end goals, and the actions they take to execute an attack. IoAs help identify the methods and behaviors an attacker uses during the attack lifecycle. Unlike Indicators of Compromise (IoCs), which are used to detect evidence of a breach, IoAs are proactive and help in identifying and preventing potential attacks before they occur by analyzing the patterns and tactics used by attackers.

• Key risk indicators: Metrics used to signal increased risk exposure.
• Indicators of compromise: Artifacts observed on a network or in an operating system that with high confidence indicate a computer intrusion.
• Indicators of exposure: Data points or signals that reveal vulnerabilities or weaknesses that could be exploited.
