Description: Gateway inspection refers to the process of examining traffic at the gateway to ensure compliance with security policies. This mechanism is fundamental in modern network architecture, acting as a filter that allows or blocks traffic based on predefined rules. Through gateway inspection, potential threats such as malware attacks or unauthorized access can be identified and mitigated before they reach the internal network. This process not only involves checking IP addresses and ports but can also include deep packet inspection (DPI), where the content of transmitted data is analyzed. Gateway inspection is essential for maintaining the integrity and confidentiality of information, ensuring that only legitimate and secure traffic can access network resources. Additionally, it integrates with other security technologies, such as intrusion detection systems (IDS) and intrusion prevention systems (IPS), to provide a defense-in-depth against various cyber threats.
