1. Introduction to SELinux The biggest security change in Redhat Enterprise Linux as 3.0/4.0 is the integration of SELinux support. SELinux, short for security-enhanced Linux, is an access control system developed by the National Security Agency (NSA. SELinux can maximize the security of Linux systems. As to how powerful it is, a simple example can prove: Linux without SELinux protection has the same security level as windows, which is level C

What is SELINUX ?, SELINUX?SELinux (Security-Enhanced Linux) is the implementation of mandatory access control by the National Security Agency (NSA) and the most outstanding New Security Subsystem in Linux history. NSA developed an access control system with the help of the Linux community. Under the restriction of this access control system, processes can only access the files needed in their tasks. SELinu

From http://www.cnblogs.com/itkm/archive/2012/03/30/2425732.html When I was a beginner at MVVM, I always thought this was a mysterious thing. Then it was inexplicably recommended by the Prism framework on the Internet, and the project was almost out of control. In fact, we need to learn everything step by step. So I am talking again today. I will repeat this matter to hope it will be helpful to the later users. And exchange the development experience

Today, with the rapid development of software technology, almost all development teams develop applications based on existing frameworks. These frameworks are either accumulated by the team or popular and mature open-source frameworks, or a commercial framework that costs money. If an open-source framework is used, the selection of the framework has an important impact on the development progress and post-Maintenance of the project. My company has recently upgraded the web application of

Describes the overall architecture of javafx 2, and describes how each part is associated with each other. You can run your javafx code based on the following javafx API. It includes javafx's high-performance graphics engine called Prism; a small and efficient window system called glass; a media engine and a web engine. Althou

principle of optical drive Let me take a look at how the optical drive works. The laser head is the heart of the optical drive and the most delicate part. Mainly responsible for data reading, so be careful when cleaning the inside of the optical drive. The laser head mainly includes: Laser generator (also known as laser diode) semi-reflective prism, objective lens, lenses and photodiode these parts. When the laser head reads the data on the disc, th

There are many kinds of mouse, the current commonly used mouse according to the principle of positioning divided into optical mouse, laser mouse, Blu-ray mouse and Blue mouse, perhaps most users do not understand the difference between them, only a few gamers have heard of these mouse types. Today we say the difference between the optical mouse, the laser mouse, the Blu-ray mouse and the Blue mouse, and the pros and cons. Ordinary Optical Mouse Positioning principle: The red side i

. using only one notebook will make future work very troublesome, in addition, if this method is used, eavesdropping may cause a small problem. In a low-usage WLAN, the chance of using active attacks is greater than that of passive detection. It can generate more packets for the WLAN in a short period of time, thus accelerating the cracking of WEP. In this lab environment, you must use a notebook. We can also use a desktop PC or desktop PC to mix with a notebook. However, if you use a notebook,
