Description: Firewall Inspection is the process of analyzing traffic passing through a firewall to enforce established security policies. This analysis allows for the identification and blocking of malicious activities, as well as ensuring that only authorized traffic can access the network. In the context of Zero Trust security, Firewall Inspection becomes an essential tool, as it is based on the premise that no user or device should be trusted, regardless of their location. This means that every access request must be verified and validated, which is achieved through continuous traffic inspection. Key features of this practice include the ability to detect threats in real-time, the implementation of granular security policies, and integration with other security solutions, such as intrusion detection systems. The relevance of Firewall Inspection lies in its fundamental role in the perimeter defense of networks, as well as in the protection of sensitive data and the prevention of security breaches. In an increasingly complex business environment with a rise in cyber threats, Firewall Inspection has become a critical component for maintaining the integrity and confidentiality of information.
