访问控制列表ACL(access-control-list)在网络安全方面发挥着重要的作用,能够灵活地对进入或离开路由器接口的分组进行过滤,这有助于控制网络流量,限制某些用户或设备访问网络。本文介绍了访问控制列表的工作流程和使用规范,并结合实验室网络通过配置ACL策略来提高实验室的网络安全。
Access-control-lists (ACLs) play an important role in network security and provide the flexibility to filter packets that enter or leave the router’s interface. This helps control network traffic and restrict access to certain users or devices The internet. This article describes the workflow and usage specifications for access control lists and improves lab network security by configuring ACL policies in conjunction with lab networks.
