Client Run ResultsExperiment Summary:In this experiment, the most difficult thing is the use of socket communication. Through this experiment, because the program code logic is initiated by the Client connection request, the server passive response, so there is a limited number of operations.It is envisaged that the RSA public-private

Microsoft Active Server Pages (ASP) is a server-side scripting environment that you can use to create and run dynamic, interactive WEB server applications. Using ASP, you can combine HTML pages, script commands, and ActiveX components to create interactive Web pages and powerful web-based applications.

SSH is the acronym for a Secure Sockets Layer, which is a set of programs that can be safely used to replace common programs such as Rlogin, rsh, and RCP. SSH uses public key technology to encrypt communication information between two hosts on the network and uses its key to
As we all know, network data transmission between different hosts is mainly completed through the TCP/IP network protocol. This is true for enterprise LAN data transmission and Internet data transmission. However, it is hard to figure out that no security was provided during the design of the TCP/IP protocol. That is to say, the TCP/IP protocol alone cannot guara

Because of the many uncertainties and spoofing nature of the load capacity, another indicator is also quite concerned, that is, throughput. Throughput refers to the amount of data that the router can process per second. This parameter refers to the throughput of the LAN-to-WAN. The measurement result is that when NAT is enabled and the firewall is disabled, use the Smartbits and Chariot test methods respectively. When using the Smartbits method, compare the 64-byte packet test data and determi

This partitioning and door-to-door approach can greatly help prevent attacks on phones, printers, or other devices. For example, a printer that has been processed by a security partition and installed with the vulnerability scanning software will not be able to access all your access port network devices.
