摘　　要：随着网络日益普及,直播带货等电子商务领域的商家和普通用户越来越倾向于将Linux网络操作系统作为其服务器的核心。作为开放源代码的免费正版软件,Linux比微软的Windows Server网络操作系统具有更为卓越的稳定性、高效性和安全性。然而,在电子商务活动的广泛应用中,操作系统本身的安全面临重大挑战,信息安全问题随之凸显。Linux操作系统提供了用户账号管理、文件系统权限控制以及文件所属群组划分等基本安全机制,若配置不当,将可能带来一定的安全隐患。因此,网络系统管理员必须谨慎地设置这些安全机制,以确保系统的稳健运行。With the increasing popularity of the internet,merchants and ordinary users in e-commerce fields such as live streaming and e-commerce are increasingly inclined to use Linux network operating system as the core of their servers.As a free and genuine open-source software,Linux has superior stability,efficiency,and security compared to Microsoft̓s Windows Server network operating system.However,in the widespread application of e-commerce activities,the security of the operating system itself faces significant challenges,and information security issues have become increasingly prominent.The Linux operating system provides basic security mechanisms such as user account management,file system permission control,and file grouping.Improper configuration may pose certain security risks.Therefore,network system administrators must carefully set up these security mechanisms to ensure the robust operation of the system.
