on the rules in the policy. When you are studying SELinux and testing the language, you may cause the program to crash due to lack of access. We recommend that you use the permissive mode (Setenforce 0) When testing your own strategy, until you are familiar with the policy language and its consequences after changing the pattern. Of course, you can also always run the system in enforcing mode (Setenforce 1

To view the process context: Ps-zExpected context: The expected contexts can also be understood as the default context, which is stored in the binary SELinux policy library.

I. Introduction of SELinuxSELinux (Secure enhanced Linux) security-enhanced Linux is a new Linux security policy mechanism developed by NSA for computer infrastructure security. SELinux allows system administrators to be more flexible in defining security policies. SELinux is a security architecture that is integrated into the Linux Kernel 2.6.x through the LSM (Linuxsecurity Modules) framework. Because

SELinux's security protection measures are mainly focused on access control of various network services. For services such as Apache, Samba, NFS, vsftp, MySQL, and Bind dns, SELinux only opens up the most basic operation requirements. As for connecting to external networks, running scripts, accessing user directories, and sharing files, a certain SELinux policy must be adjusted to give full play to the role

/access_vectors, which corresponds to every command that a class can be allowed to executeC. Only one role is defined in Android External/sepolicy/roles, and the name is R, associating R with attribute domain.D. external/sepolicy/users is actually associating user with roles, setting the user's security level, S0 the lowest level is the default level, Mls_systemhigh is the highest levelE. External/sepolicy/security_classes refers to the class in the above command, which personally considers the

SELinux causes disk I/O problems-Linux Enterprise applications-Linux server application information. The following is a detailed description. Yesterday, the new server in the Changchun data center crashed at night. After restarting in the morning, check that % util occupied 100% of the system disk. why can't I get down? I stopped all the applications, but I still don't know if it was SELinux.

In 2000, researchers at William Mary College in the United States, Serge, and others at the Usenix 4th annual Linux Showcase conference Conference, published the title "Domainand Type Enforcement for Linux "article. The first time this article used the DTE model for Linux, the DTE Linux prototype system was implemented.The same year, the NSA's Stephen Smalley and others released the open source Linux security framework Selinux,
