yearsIn general desktop and program development environments, SELinux policies can meet the security and convenience requirements at the same time..Taking the just-released fedora 15 as an example, the author builds a complete entertainment environment (including multiple third-party native Linux games and wine games) and development environment (AndroidSDK + eclipse), only the first running of the wine program is blocked by the default

many user-layer libraries and tools that can use the SELinux function.SELinux is a domain-type-based Mandatory Access Control (MAC) security system. It is written and designed by NSA to include the kernel module into the kernel, some security-related applications are also patched with SELinux, and finally there is a corresponding security policy. Any program has full control over its resources. If a progra

In SELinux, multiple policy modes are preset, and we usually do not need to define our own policies unless we need to protect some services or programs. In CentOS/RHEL, the target policy is used by default. What is the target policy? The targ

It may also is a better option to do changes to the policy to permit the operations that is being blocked-but this re Quires knowledge of writing policies and May is a steep learning curve for some people. For the operating system as a

parameter that is used to determine whether your system's kernel is running in force (enforcing) or free (permissive) mode, which is the "enforcing" parameter. In free mode, SELinux just records what he should do, and in fact doesn't do any action. In mandatory mode, SELinux will come to the bottom. If your policy has errors, the system may prevent you from logg
