As two major operating systems, Linux and Windows have their own advantages and generations, and safety is also tested. Building system security will be able to give users a full reason to use Linux.
Ramen, Slapper, Scalper and Mighty These names are like the name of cute little deer in the Santa Zoo, but they are not, they are attacking Linux servers in recent months, using Linux servers to launch over-distribution refusal service attacks Worm virus name. Survey many of the more secure Linux users who have been more secure than Windows users, they have begun to be too optimistic. In fact, we are really difficult to distinguish between two different software systems in an objective area, especially in the face of such a large system. Linux and Windows are currently different from the application range, although it is the most direct competitor, it is difficult to see the competition in the face. IDC Analyzer Close-Christian has pointed out: "The Linux-UNIX operating system is mostly used in server environments, while most of the Windows systems are used in stand-alone environments." The user technology level will directly affect their stability of operating system Sexual assessment. The evaluation angle of the two operating systems is also different. Linux-UNIX developers are improving the stability of the system and found that any problems are considered a good thing. This article will talk about Linux and Windows from the perspective of security. There are two main reasons for security defects in Windows, one is that it is too young, and the other is to use its users. But Linux is younger than Windows, and there is no commercial organization responsible for it, security defects in Linux are more than Windows. BugTraq related to Linux is more than any version of UNIX or Microsoft's operating system. An operating system is more secure than another operating system that does not meet the objective situation of the real world. Open source code operating systems and proprietary source code operating systems are facing a threat of security defects. In which operating system is more secure, the open source operating system seems to occupy the wind. The industry insiders of open source operating system believes that although not open source code, most of them are unclear with security defects in the proprietary source operating system, but this does not mean that there is no safety defect, and there is very likely to have system management. The more serious security defects don't realize. Objective analysis, those who have just contacted free software or open source software often have some concerns about their safety, which is understandable. Imagine that everyone can see the source code. If the vulnerability is found and used to attack me, then? However, why is free software and open source software, or some of Linux has a safe reputation? It is necessary to say a few aspects. The author believes that the security of a system is primarily on whether it will be in the heart when designing. It is not polite, the security of Windows is also gradually improved after Windows NT, but it does not introduce this security point of view to Windows 98, this once in the system, and even user permissions are not Clear provisions. LINUX as a class UNIX system, from the most beginning, the concept of multi-users and permissions is always always. From this point of view, the author thinks Linux is safe than Windows. Even if the Trojan is just a normal user, it will not have a big impact on the system, as it may even have many programs and file access rights. In fact, in the user now, take Windows 2000 and XP as a desktop user, there are many users with administrator privileges, and XP to the default user permission is ROOT level, this itself is buried. Security risks. But some people think that what is the defects caused by these design? Linux is much smoldering because there are too few users, but they are hidden because they are ignored. If you overturn Windows because of this, it is too simple. In fact, the security vulnerabilities of Linux and other open source system software are also quite serious.
