Problems solved by technology
Traditional general-purpose operating systems basically use access control at the IP layer or application layer to allow or restrict data transmission
The problem with this method is that when there is a loophole in the operating system, the IP layer or application layer can usually be easily bypassed, causing the security of the operating system network to be destroyed.

The invention provides a data access control method for a network driver layer in an operating system, which comprises the steps: setting an authority limit rule base and performing dynamic management to the authority limit rule base, wherein the authority limit rule base records rules adopted by a network data packet and a network device of the operating system; monitoring a transmitting data packet and a receiving data packet of a network card and information of the transmitting data packet and the receiving data packet through a network card accessing and controlling monitor in real time, and acquiring a data packet on an existing data path of a network and data information corresponding to the data packet on the existing data path; loading the authority limit rule base by the network card accessing and controlling monitor, matching the data information corresponding to the data packet on the existing data path with the rules in the authority limit rule base, and processing the data packet on the existing data path according to matching results. The data access control method for the network driver layer in the operating system introduces an accessing control technology to the network driver layer in the operating system, thereby improving control of the network device and the network data by the operating system and enhancing the network safety of the operating system.
Description
technical field [0001] The invention relates to the field of computer science and technology, in particular to a data access control method of a network driver layer in an operating system. Background technique [0002] Access control is to restrict the user's access to certain information items or to restrict the use of certain control functions according to the user's identity and a defined group to which he belongs. It is usually used by system administrators to control users' access to network resources such as servers, directories, and files. Traditional general-purpose operating systems basically use access control at the IP layer or application layer to allow or restrict data transmission. The problem with this method is that when a loophole occurs in the operating system, the IP layer or the application layer can usually be easily bypassed, so that the security of the operating system network is destroyed. Contents of the invention [0003] The purpose of the pre...
