Step-by-step explanation:
The type of firewall that provides the greatest degree of contextual information and can include information about users and applications in its decision-making process is NGFW (Next-Generation Firewall).
NGFW combines traditional firewall features with advanced capabilities such as intrusion prevention, application awareness, and user-based policies. It can analyze network traffic at a deeper level, taking into account factors like the identity of the user, the application being used, and the content of the data packets.
For example, NGFW can allow or block specific applications based on user roles or prioritize bandwidth for critical applications.
