随着网络安全威胁的不断升级，传统的包过滤技术已难以满足需求。深度包检测技术通过分析数据包的内容，实现对网络威胁的精准识别和防御。交换机搭载深度包检测技术，可以进一步提高网络安全防护的效率。 2. 入侵检测与防御系统（IDS/IPS）集成 将入侵检测与防御系统（IDS/IPS）与交换机集成，可以实现更加高效的网络安全防护。IDS/IPS系统可以实时监测网络流量，发现潜在的攻击行为并进行阻断。通过与交换机的协同工作，可以进一步提高网络安全防护的实时性和准确性。 三、英文翻译 New Weapon of Network Security: The Role of Switches in Protection With the rapid development of internet technology, network security issues have become increasingly prominent. As one of the core devices in the network infrastructure, switches play a crucial role in ensuring network security. This article will explore the new role of switches in network security protection. Firstly, the role of switches in network security. 1. Data Filtering and Access Control Switches can achieve data filtering and access control through configuring Access Control Lists (ACLs). Only data packets that meet the ACL rules can be transmitted through the switch, effectively preventing unauthorized access and malicious attacks. 2. Isolation of Network Attacks When the network is under attack, switches can quickly isolate the affected ports or devices to prevent further spread of the attack. This isolation mechanism helps to protect the entire network's security and reduce the risk of network failures. 3. Monitoring Network Traffic Switches can monitor network traffic in real-time and detect and alert on abnormal traffic in the network. This helps to discover network attacks and abnormal behavior in a timely manner, providing strong support for network security protection. Secondly, new applications of switches in network security protection. 1. Deep Packet Inspection Technology With the continuous upgrading of network security threats, traditional packet filtering technology has been difficult to meet demand. Deep Packet Inspection technology achieves accurate recognition and defense of network threats by analyzing the content of data packets. By integrating deep packet inspection technology into switches, it is possible to further improve the efficiency of network security protection. 2. Integration of Intrusion Detection and Prevention Systems (IDS/IPS)

Integrating Intrusion Detection and Prevention Systems (IDS/IPS) with switches enables more efficient network security protection. IDS/IPS systems can monitor network traffic in real-time, detect potential attacks and block them. By working together with switches, it is possible to further improve the real-time and accuracy of network security protection. Overall, with the development of new technologies and application scenarios, switches have played a vital role in enhancing network security protection. We should continue to explore the potential and value of switches in the field of network security, to better protect our networks from various threats and challenges.
