With the increasing popularity of networks, security issues have attracted more and more attention. Linux, as a free open-source operating system, is increasingly used as a server platform. With the diversity of application software in Linux, many people (including the author) also like to use Linux as a desktop. In th

store logs. TIPS: In a Linux system, there are three main log subsystems: (1) connection time logs. Executed by multiple programs, writing records to "/var/log/wtmp" and/"var/run/utmp", login, and other programs to update wtmp and utmp files so that system administrators can track who is logged on to the system. (2) Process statistics performed by the system kernel. When a process terminates, write a record in the statistics file. The purpose of pr

Abstract: The Access Control Model for traditional UNIX systems is very simple-for common users, Super Users. In this model, a process or account has either very small permissions or all system permissions. Obviously, this is of no benefit to system security. Starting from the Linux-2.1 kernel, the concept of capacity is introduced to achieve more fine-grained access control. 1. Introduction UNIX is a secur

The preceding important Linux security commands involve important commands for user and file permissions. Today we will introduce the chattr, sudo, ps, and who commands. Here we have completed all the important Linux security commands, and hope this course will help you. VII. chattr 1. Role Modify the attributes of th

Many people think that Linux is safer than Windows. However, today, security is even more important. This kind of security still requires the correct configuration of users. This kind of security does not have to be achieved through some specialized security software or tech

I have seen many good articles on linux Optimization on the internet, and I will not repeat these articles here. I just want to talk about these issues from my own experiences. As a system administrator, I will talk about linux based on server applications. Since linux on a personal computer may not be the same as on a server,

Fedora has a lot to learn about. Here we mainly introduce Linux security, including Fedora and other aspects. The Linux release of Fedora Core Linux, and Red Hat's original Linux development team will continue to participate in the development of this release.

Install/etc/security/limits. conf in linux. In linux, Oracle is usually installed with/etc/security/limits. conf file, but the specific meaning here may not be everyone's. At the beginning, I didn't clear it very much. I only knew to modify it. Every installation can follow the configuration in the document. Today, I

, and its security can be enhanced at the code level. But it is too complicated for users who are new to Linux. If you want to use Linux as a desktop operating system, the settings must be different from those on the server. The server may be used on the Internet, whether it is its firewall, proxy server or other applications,

Linux system security is guaranteed in many aspects. Here we mainly introduce the knowledge of Linux port security, which involves the setting of Linux ports. Here we summarize some things from the Internet, now let's share it with you. Here, we usually need to pay attention

Thanks to the outstanding functions and reliable stability of the Linux operating system, more and more users are learning and using Linux. In the course of studying and using Linux, I have also collected and sorted out some tips for Linux security management. Now I will mak

Do you want to evaluate the security of Linux without having to go through lengthy installation and configuration processes? In this article, we will introduce four packages: Auditor, Whoppix, Knoppix-STD and phak. After using these packages, you can use LiveCD.A truly secure system can only be shut down and powered off, placed in a closed room in a concrete pouring building, and equipped with police to gua
