Article Title: ensures system security by monitoring processes running in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. By using user-level top, ps, and other system tools

In this article, I will discuss how to configure a Unix client based on the Network File System and use Kerberos security verification through the rpcsec_gss protocol to connect to a Windows Server under the Network File System. Traditional Network File System clients and servers use

Buffer overflow attacks are currently one of the most common attacks by hackers. to cope with the emerging buffer overflow attacks, we have studied how to prevent buffer overflow in Linux, summarizes the security policies for preventing buffer overflow attacks on the Linux platform. these security policies can be applied to internal enterprise servers. Buffer overflow attacks are currently one of the most c

Virtualization technology enables multiple operating systems to run application software on the same computer, which can better manage and use IT resources, thus attracting the attention of IT managers. However, some IT managers and security researchers have warned enterprises that the technical problems presented after virtualization will make their systems more vulnerable to hacker attacks. Chad Lorenz C, a technical

Before a disaster arrives, we can make a lot of preparations to avoid the disaster, but we can't help but think about what we should do if the disaster really strikes? For system reinforcement, we also need to be fully prepared. Highlights of "security" 1. Try to install the English version of the operating system If you only want to improve the

Because UNIX systems often undertake key tasks, they are often the first choice for intruders to attack. Therefore, intrusion detection and system security protection are one of the most important tasks of administrators. So, without the help of other tools, how can we determine the current security of the system? How

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 ac

I. Web Server Security PHP is actually a module function of the Web server. Therefore, you must first ensure the security of the Web server. Of course, to ensure the security of Web servers, you must first ensure the system security. This is a long way to go and is endless.

Unix SystemIn, some programs use the systemRootProcess running. These programs do not always have suid permission, because many of them only run by the root, the system administrator needs to know what these programs are doing and what other programs these programs will run. (1) Start the system When some unix systems (such as sco unix/xenix) are started, they are run in a way called a single user. In this

How to prevent an attacker from illegally stealing important information from an FTP server, and how to prevent an attacker from using an FTP server to spread trojans and viruses. These are issues that the system administrator needs to focus on. This time I'm going to talk about how to improve the security of the FTP server, as an example of the broadest vsftp used on Linux operating
