Different TCP/IP layers provide different security. For example, a virtual private network is provided at the network layer and a secure connection service is provided at the transmission layer. The following describes the security of TCP/IP at different levels and the methods to improve the security of each layer.I.

operating system and protocol software to manage the main tasks related to the network access layer. The modularization of the protocol stack enables software components in the network access layer dealing with hardware to provide interfaces for the upper layers unrelated to hardware. Network access layer and OSI model-- The physical layer in the OSI model is responsible for converting data frames into bit streams suitable for transmission media. The data link layer completes two independent ta

The IP protocol is the most important protocol in the family of TCP/IP protocols, which provides unreliable, non-connected datagram transport services.

International regulations: divide all IP addresses into A, B, C, D, and E. Class DefaultSubnet Mask: Class A is 255.0.0.0; Class B is 255.255.0.0; Class C is 255.255.255.255.0. The subnet mask is a 32-bit address. It is used to shield a part of the IP address to distinguish the network ID and host ID, and shows whether the IP address is on the LAN or on a remote
