CentOS disable Selinux

CentOS disable Selinux Selinux: SELinux (Security-EnhancedLinux) is the most outstanding New Security Subsystem in Linux history for implementing mandatory access control by the National Security Agency (NSA. Although it is a security function, it is more troublesome to use because there are too many functions and everything needs to be managed. Therefore, you can disable it and use other security methods instead. [1] view three modes of Selinux oper

"What I need is the functionality and assurance of security devices," said Brian snow, an NSA encrypts at the 2005 computing security application conference. We will not use customers for testing. If my product fails, someone may pay for it ." Therefore, remember that errors do not only result in the cost of money. Users should be assured. Obtaining an

Secure Programming: minimize privileges to eradicate software defects

a principle (see references ). There are some ideas that are permanent, such as minimizing privileges.    The next three sections will discuss these goals in sequence, including how to implement them in UNIX-like systems. Next, we will discuss some of the special mechanisms available in FreeBSD and Linux, including the Security-Enhanced Linux (SELinux) discussion of NSA.       Minimize privileged modules As mentioned above, only some programs that re

, such as vulnerability exploitation, worms, and Trojan rootkit, comply with the principles of the above war laws. 1. Vulnerability Exploitation Basically, it refers to an undisclosed zero-day vulnerability that can be exploited to gain control over information technology devices. The Triss (Triss) malware mentioned above is a zero-day vulnerability attack. 2. Worms A self-replication network weapon can be used to search for specific vulnerabilities, exploit these vulnerabilities, and infect any

How to Protect Your CentOS Operating System

In this world, Linux operating system security is very important. But you have to know how to do it. A simple anti-malware software is far from enough. You need to take other measures to work together. Try the following methods. 1. SELinuxSELinux is used to reinforce Linux security. With it, users and administrators can control access control more. SELinux adds finer Granularity Control for access control. And can only specify who can read, write, or execute In this world, Linux operating system

Swift vs. Objective-c: 10 Reasons to watch Swift in the future

.8. Swift supports dynamic librariesOne of the biggest problems in Swift that has not received enough attention is the switchover of the static library to the dynamic library, which is updated in the main release (IOS8,IOS7, etc.). A dynamic library is an executable block of code that can be linked to an app. This feature allows existing swift applications to link to the updated version of the Swift language that has been generated over time.Developers submit the app together with the library fi

algorithm, MD5 and SHA-1 is the most widely used hash algorithm, and they are based on MD4 design. Introduction of commonly used hash algorithms:(1)MD4MD4 (RFC 1320) was designed by MIT's Ronald L. Rivest in 1990, and MD is the abbreviation for message Digest (Messages Digest). It is implemented with high-speed software on a 32-bit word processor-it is based on a bitwise operation of 32-bit operands.(2)MD5MD5 (RFC 1321) is an improved version of Rivest in 1991 for MD4. It still groups the input
