    • A method and a device for setting up a security policy for a secure OS(Operating System) are provided to remove complexity by reducing the number of types and rules remarkably based on comparison with a usual SELinux(Security Enhanced Linux) security policy setting mode, and enable a user having no specialize knowledge to set up or control the desired security policy easily. An SELinux security policy template(51) comprises a form for setting up a subject, an object, and a subject's right for the object. A converting module(52) converts the security policy template into a TE(Type Enforcement) security policy(53) applicable to SELinux. The security policy includes a subject element defining the subject accessing the object, an object element defining the object accessed by the defined subject, a right element defining an access authority between the defined object and subject, and a transition element defining domain transition. The converting module includes a parser(521) parsing the security policy template, and a generator(522) generating more than one of a subject domain, the domain transition, an object type, and a TE operation from the parsed data, and generating TE context by combining the same.
    • 提供了一种用于设置安全操作系统(Operating System,安全操作系统)安全策略的方法和设备,以通过与通常的SELinux(安全增强型Linux)安全策略设置模式进行比较来显着减少类型和规则的数量来消除复杂性, 并且使得不具有专业知识的用户容易地设置或控制期望的安全策略。 SELinux安全策略模板(51)包括用于设置对象的对象,对象和主体的权利的表单。 转换模块(52)将安全策略模板转换为适用于SELinux的TE(Type Enforcement)安全策略(53)。 安全策略包括定义访问对象的主体的主题元素,定义由定义的对象访问的对象的对象元素,定义被定义的对象和对象之间的访问权限的正确元素以及定义域转换的过渡元素。 转换模块包括解析安全策略模板的解析器(521),以及生成器(522),从解析的数据生成多个主题域,域转换,对象类型和TE操作,以及生成TE 上下文相结合。
