coarse grained access control

Oracle allows several PL/SQL APIs (UTL_TCP, UTL_SMTP, UTL_MAIL, UTL_HTTP, and UTL_INADDR) to access external network services. These APIs use the TCP protocol in the previous database version (10 Gb) it is implemented through an on/off switch based on whether the user is authorized to execute a package. Oracle 11g introduces fine-grained access to network service

in the door to enter the system, once the identification of the completion of the door, but let go, there are few treatment options. The focus of this article is not how to authenticate, and after the completion of the identity authentication is also entered the system door, how to ensure that users only in their own scope of access to operate, rather than can be any function of the operation of the system is the internal fine-

The commonly used rights system design pattern is role-centric, where a role is a collection of people with the same permissions:1. A role can have multiple operators, an operator can also belong to multiple roles2. A role can have multiple functions of operation permissions, a function can also be owned by multiple roles.By querying the user's role when logging in, you can get all the feature sets for a user, such as:Most Business System page function menu design is a three-level standard, that

"General" characteristics as the Permission Logic. Status quo: There are generally three access control methods in the enterprise environment: 1. Autonomous access control method. At present, the access control module in most inf

User Root in Linux, so it is not restricted by DAC. Second, DAC cannot prevent Trojans. For example, a Trojan horse has been hidden in a program approved by the user, this program may cause harm to the computer system. Thirdly, the DAC control granularity is coarse and cannot effectively implement fine-grained access

function corresponds to different menus of the two systems. The user menu (UserMenus) is similar to the user and function (UserPowers), and the system changes according to the corresponding permissions of the personnel. 2.3 system running mode The system is built in the. Net environment and is divided into two versions: B/S and C/S. The same business logic is used. The only difference is the display mode. Same running mode: (1) The user must pass identity authentication when logging on. This p

The user access control mechanism is always discussed in terms of coarse-grained and fine-grained two aspects: Coarse-grained control: You

allows users to browse a page and refuse users to publish data on untrusted servers. 3) Data Control: the firewall can control the passage of application data streams. For example, the firewall can block viruses in email attachments. The scale of firewall access control depends on the technologies it can implement. Ho

second and third-level systems actually adopt the host-type autonomous access control mechanism. Based on in-depth analysis of the security risks of traditional operating systems, jiaotu technology applies the host-type autonomous access control mechanism to JHSE products to enhance the security of the operating syste

Document directory Fine-grained access to network services Grant Permissions In oralce 11g, if you want to obtain the Server IP address or hostname, run the following statement: Select utl_inaddr.get_host_address from dual; // obtain the IP address Select utl_inaddr.get_host_name from dual;// Obtain the Host Name If the execution can be normal in Oracle 9i, but you may get an inexplicable error mess

: when initiating an activity or returning a result to an activity, the caller can set the intent.flag_grant_read_uri_permission and /or Intent.flag_grant_write_uri_permission. This causes the activity that receives the intent to gain access to the URI specified by the intent, regardless of whether it has permission to enter the intent corresponding content provider.This mechanism allows a common Capability-style model, which is driven by user interac
