The feature that should be enabled on a firewall to ensure all traffic is inspected and abides by the AUP (Acceptable Use Policy) and that malicious traffic is stopped is Content Filtering.
Content filtering is a technique used to block or allow access to specific websites, services, protocols, or types of traffic based on predefined rules or policies. Content filtering can be implemented using various methods, such as URL filtering, IP filtering, keyword filtering, and file type filtering.
By enabling content filtering on a firewall, the network administrator can set up rules that specify which types of traffic are allowed or blocked. The administrator can define specific categories of websites or services that are allowed or blocked, such as social media sites, gambling sites, streaming media sites, or file-sharing services.
Content filtering can also help enforce the AUP by blocking traffic that violates the policy. For example, if the AUP prohibits employees from accessing certain websites or downloading certain types of files, the administrator can configure the content filtering rules to block access to those sites or files.
Moreover, content filtering can detect and block malicious traffic, such as malware, phishing attempts, and spam. The administrator can create rules that block traffic from known malicious IP addresses or domains, or that filter out suspicious content based on keywords or file types.
Intrusion detection, proxy services, and dynamic DNS are other features that can be enabled on a firewall, but they do not directly address the requirement of ensuring all traffic is inspected and abides by the AUP and stopping malicious traffic.
Intrusion detection refers to the process of monitoring network traffic for signs of unauthorized access or malicious activity. It can alert the administrator when an intrusion is detected but does not necessarily block the traffic.
Proxy services can be used to provide anonymous access to the internet or to cache frequently accessed content to reduce bandwidth usage. However, they do not provide granular control over traffic filtering and may not be effective at stopping malicious traffic.
Dynamic DNS (Domain Name System) is a service that maps domain names to IP addresses dynamically, allowing hosts with dynamic IP addresses to be accessible via a fixed domain name. While useful for managing dynamic IP addresses, it does not provide any traffic filtering or security features.
