It can be viewed using the command ls-z, as shown in this security context consisting primarily of three parts So how does the/usr/sbin/httpd process in the/var/www/html/access the files in the directory through SELinux decisions? First of all,/usr/sbin/httpd this file has httpd_exec_t this type, when executing this file, will let the main process of this file has httpd this domain, and SELinux policy has made a lot of rules for this

. Similarly, even if the user has permission to operate on a database, is it possible to manipulate all the tables? Can I manipulate all the records in a table?2. The tables_priv table is used to set permissions on a single table 3. The Columns_priv table is used to set permissions on a single record (column) 4.

First look at the database There are a total of 5 tables, users,roles and roleswork 3 tables with another 2 tables form a "W" type of relationship, is also a more common way to access the database, first of all to do th

Project Introductionprivilege system has always been an indispensable part of our application system, if each application system to re-design the system's permissions to meet the needs of different system users, will waste our valuable time, so it is very meaningful to spend time to design a relatively universal permission system. The design goal of this system is to control all the resources of the application system, such as the function menu of the application system, the various interfaces a

OA system is divided into many modules, such as the System Management module, and some more advanced business operations. This kind of business is not allowed to allow ordinary employees to operate, the idea is as follows:Add a role table to the system, each user has a role, each role can have multiple permissions,As follows: Create permission table (PRIVILEGE):The table defines the name of the permission action and the action path that can be manipul

The ability to expand or customize what you want to do is very useful. But we need to maintain the session. For example, the system is republished, or IIS is automatically restarted.
