A Circuit Level Gateway operates at the session layer of the OSI model. It monitors the TCP handshake to ensure that the session is legitimate and can intercept the communication. This type of firewall does not inspect the packets themselves but rather ensures that the connection is valid. It can be seen as a middleman that relays TCP connections between the user and the external network, making it appear as if the firewall is the source or destination of the communication. This is a cost-effective solution that complements the existing packet filtering firewall by adding session-level control without the need for deep packet inspection or application-level gateways, which can be more resource-intensive.

Data in Use refers to data that is actively being processed by the system, including data stored in RAM, CPUs, or databases during computation. This data is currently in memory and being accessed or manipulated by applications, making it vulnerable to attacks that target active processes, such as memory scraping or CPU-based attacks.

Data at Rest: Data stored on disk or other persistent storage media.

Data in Transit: Data being transferred over a network.

Data in Backup: Data stored in backup storage for recovery purposes.

WPA3, or Wi-Fi Protected Access 3, is the latest security certification program developed by the Wi-Fi Alliance that provides enhanced password protection, secured IoT connections, and encompasses stronger encryption techniques. WPA3 introduces several enhancements over its predecessor, WPA2, including:

Better protection for simple passwords: WPA3-Personal uses the Simultaneous Authentication of Equals (SAE) which provides protection against password guessing attacks even when users choose simpler passwords.

Enhanced encryption for personal networks: It employs individualized data encryption to protect against eavesdropping on Wi-Fi networks, and it uses a more secure encryption algorithm, Galois/Counter Mode Protocol (GCMP-256), compared to the Advanced Encryption Standard (AES) used in WPA2.

Improved security protocols for enterprise networks: WPA3-Enterprise offers the equivalent of 192-bit cryptographic strength, providing additional layers of authentication and data protection for enterprise networks.

Wi-Fi Enhanced Open for open networks: This feature encrypts traffic on open networks without requiring a password, increasing the privacy and security of users connecting to public Wi-Fi hotspots.

Non-repudiation is a fundamental attribute of network defense that ensures that neither party can deny the authenticity of their communications. In the context of Simran's actions as a network administrator, by mandating authentication before any connection establishment or message transfer, she is ensuring that the identity of the communicating parties can be confirmed and that the parties cannot later deny having sent or received the messages. This is crucial for maintaining accountability and trust within the network, as it provides irrefutable proof of the origin and integrity of the communications.
