三、访问控制功能 访问控制是路由器安全功能的另一重要组成部分。通过设置访问策略，路由器可以限制不同用户对网络资源的访问权限，从而防止未经授权的访问。此外，访问控制还可以实现基于时间、地点、设备等多种条件的访问控制，提高网络安全性能。 四、入侵检测与防御功能 入侵检测与防御是路由器安全防护的重要手段。通过实时监测网络流量，路由器可以检测出潜在的攻击行为，并采取相应措施进行防御。此外，路由器还可以对已知的攻击行为进行特征识别和阻断，防止攻击者对网络进行破坏。 五、VPN加密功能 VPN（虚拟专用网络）加密功能是路由器保障网络安全的重要手段之一。通过VPN技术，用户可以在公共网络上建立加密通道，实现安全的远程访问和数据传输。VPN加密功能可以有效保护用户的隐私和机密信息，防止信息泄露。 六、英文翻译 A New Choice for Network Security: A Comprehensive Analysis of Router Security Functions With the popularity and rapid development of the Internet, network security issues have become increasingly prominent. As the core device for connecting home and enterprise networks, the importance of router security performance is self-evident. This article provides a comprehensive analysis of router security functions to provide new options for ensuring network security. Overview of Router Security Functions Router security functions mainly include firewalls, access controls, intrusion detection and defense, VPN encryption, etc. These functions together form the security protection system of the router, effectively resist network attacks and ensure the security and stability of network communications. Firewall Function The firewall is one of the most basic security functions of the router. By setting access rules, the firewall can filter out illegal accesses from unsafe networks and protect the internal network from attacks. Additionally, the router firewall can also control access to internal network resources, preventing unauthorized access by internal users. Access Control Function

Access control is another important component of router security functions. By setting access policies, routers can limit the access permissions of different users to network resources, thereby preventing unauthorized access. Furthermore, access control can also implement access control based on various conditions such as time, location, and equipment, improving network security performance.

Intrusion Detection and Defense Function Intrusion detection and defense are important means of router security protection. By monitoring network traffic in real time, routers can detect potential attack behaviors and take corresponding measures for defense. Additionally, routers can also identify and block known attack behaviors by characteristics to prevent attackers from damaging the network. VPN Encryption Function VPN (Virtual Private Network) encryption function is one of the important means for routers to ensure network security. Through VPN technology, users can establish encrypted channels on public networks to achieve secure remote access and data transmission. The VPN encryption function can effectively protect user privacy and confidential information to prevent information leaks.
