Desktop migration to Linux 4 questions do you know

Computer shop news As early as the 1990s, with the prosperity of the network economy, Linux desktops are coming out, and a number of Linux vendors such as Redhat and Mandrake are proposing to develop Linux desktop systems. However, because it was limited to the concept at the time, it was difficult to provide users with detailed usage. People felt a bit of a sensation. However, with the increasing security of Microsoft Windows and the continuous development of Linux desktop technology, organizations using Linux And more and more individuals. This article focuses on the advantages of Linux desktops in terms of technology, cost savings, desktop management, and customer satisfaction. How is security? Although Linux has many security features and attributes, here we mainly focus on the points related to the desktop. Browser Security Linux desktops mainly use open source browsers. These browsers are not integrated with the operating system. They are independent applications under the control of the operating system. This means that the installation of the browser under Linux can be ROOT users. Currently, there are many browsers available under Linux, such as Mozilla, Opera, and Konqueror. Instant Messaging Security Instant messaging programs are software that communicates over the Internet via the TCP/IP protocol, including email programs and web chat programs. The instant messaging application under Linux is also open source and independent of the operating system, which means that all the advantages listed above for the browser also apply to instant messaging programs, and because of the current instant messaging program under Linux. Multiple protocols can be supported at the same time, and Linux users have the flexibility to choose to use any protocol and service. User privilege division User security is an important part of Unix. Linux is a multi-user operating system similar to Unix. It can use this core feature to divide users. Only ROOT users can have administrator privileges and manage user security levels. . A typical security application under Linux is to distinguish the login environments of different users. Except for ROOT users, no one can log in as an administrator. Bugfix Response Time An important factor affecting security use is time. The size of the problem caused by a security vulnerability is very much related to the time the hacker can take advantage of. Because most components of the Linux desktop are open source, Bugfix will be modified in the community, or obtained from some enterprise vendors, and the response time is very short. The firewall supports the Linux kernel to provide firewall services. The 2.4 version of the Linux kernel provides the firewall as an iptable. Proper configuration of Iptables can help administrators implement security policies on the Linux desktop. How much does it cost Linux license and support costs The Linux kernel and most applications are open source, so there is no license for users of Linux, but the commercial version of Linux released by the publisher is not free. If you choose the Linux operating system provided by the community, you can not only get a free license, but also get free and well-trained personal technical support in the community. Hardware Costs Most Linux distributions can run on very old hardware devices. According to the customer's actual situation, many old devices that can't meet the latest version of Windows installation requirements can still run Linux. Although the latest enterprise release also proposes minimum memory requirements, computer systems that are lower than the minimum memory requirements can still run these distributions. The cost of the application The Linux distribution includes many basic applications that cost little or no. Even if some applications are not in the distribution, you can find free apps in the open source community. Management and support costs are very low In general, maintaining the security of an available operating system and preventing hacking costs is a huge expense. But because Linux is a Unix-like operating system, you can use Telen or SSH to remotely log in and maintain, which can save a lot of money. Use remote scripts to monitor customer issues and perform tasks from a central server to resolve issues. For example, to modify a program problem, you can get a patch and install it by remotely executing a script on the desktop, and the end user has not noticed it. There are many open source communities for the corresponding management tools, and many system management tools provided by enterprises can be used. Easy to manage? The modular structure of the operating system The Linux kernel is a modular structure, which means that the kernel is not fixed, consisting of a very small binary kernel and a variety of kernel modules, the kernel module can be needed When loading, some modules must be loaded at startup because these are necessary to read the file system or use the hardware. Not only is the kernel modular, but the framework of the application on the kernel is also modular. Upgrade and patching mechanism Upgrade or patch the Linux operating system. In addition to affecting the kernel or running programs, there is no need to restart it like Windows repeatedly. You can make plans to make the system automatically upgrade. Linux Embedded Remote Access The Linux operating system supports remote access via TCP/IP protocol for remote management. Because almost all tasks can be performed remotely, SSH remote management is used. Remote access mainly accomplishes two important management tasks: First, remotely execute the hypervisor or monitoring scripts, such as enabling all users to upgrade the virus database, or to secure patches, clear temporary files, and so on. The second is to provide support for customers, all questions raised by users, in addition to the network, you can basically log in through the remote configuration, view configuration and log file resolution. Can it be customized on demand Sometimes it is very important to customize the system to be used according to the customer's needs. If you release an operating system distribution that includes all applications, you will find that the distribution takes up a lot of space and is very difficult to maintain, so deploy Linux. Customizing the customer desktop is a very important strategic consideration when it comes to the desktop. Based on the characteristics of Linux, we can flexibly choose the components to be used during installation, which can prevent the user's desktop system from being over-expanded. Different applications can be assigned to different users, and a very professional distribution can be customized according to the user's work, such as image workstation. , signal processing workstations, etc., can freely choose the user interface style.
