Domain name
A domain name is actually the name of a computer that is connected to the Internet. Its function is as important as writing people's names and addresses in a mail. The domain name structure is as follows: Host Name of the computer. organization name. Network Name. top-level domain name. Domain names are expressed in text, which is easier to remember than IP addresses expressed in numbers. All levels of networks that join the Internet follow the naming rules of DNS to name the computers in the network, and are responsible for converting the domain name to IP address during communication.

DNS Server
DNS (Domain Name System) refers to the directory service System that queries the Domain Name or IP address on the Internet. When receiving a request, it can translate the domain name of another host into an IP address or vice versa. Most domain name systems maintain a large database that describes the ing between domain names and IP addresses, and the database is regularly updated. A translation request is usually sent from another computer on the network. It requires an IP address for route selection.

IP address
An IP address is a 32-bit IP address assigned to the host. It consists of 4 bytes and is divided into dynamic
Static IP addresses. Dynamic IP addresses refer to different addresses obtained by each connection, but static IP addresses
The status IP address is the same fixed address for each connection. Generally, the address obtained by dialing
All are dynamic, that is, the obtained address is different each time.

TCP/IP Transmission Control Protocol/Internet Protocol
TCP/IP communication protocols mainly include the standards of network communication details on the Internet, as well as a set of network interconnection protocols and path selection algorithms. TCP is a transmission control protocol, which is equivalent to an item packing list to ensure that data is not lost during transmission. The IP address is an inter-network protocol, which is equivalent to the address and name of the recipient and ensures that the data arrives at the specified location.

TFTP Common File Transfer Protocol
TFTP is a simplified FTP protocol used by diskless computers to transmit information. It is very simple, so it can be solidified on the hard disk, and supports non-authentication operations. TFTP is a very insecure protocol.

UUCP is a cat-based file transfer protocol that has been used for a long time. Sometimes it is used to transmit Usenet news and E-mail over the Internet, especially on disconnected websites. Currently, few websites provide anonymous UUCP to access files. It is a File Transfer Protocol, which is used only by users who do not access the network and use the cat.

WWW
WWW (Word Wide Web) is the latest Internet Information Service. It is an interactive browsing and retrieval tool based on Hypertext files. You can use WWW to browse, transmit, and edit files in hypertext format on the Internet.

Usenet
Usenet is the main information source of the network news server. Usenet is a user communication network established by the masses, which uses the Internet to exchange information but is not completely dependent on the Internet for communication. Volunteers who use Usenet abide by some agreed network usage rules.

CGI public Gateway Interface
CGI (Common Gateway Interface) is a program that can produce the same results or the results change with user input. It can be written in an explanatory interface language or a compilation programming language. CGI specifies the interface protocol standard for the Web server to call other executable programs. The Web server calls the CGI program to implement interaction with the Web browser, that is, the CGI program receives and processes the information sent to the Web server by the Web browser, then, the response is sent back to the Web server and Web browser. CGI programs generally process form data on Web pages, query databases, and integrate with traditional application systems. Although CGI programs can be written in any programming language, CGI programs written in C language have the features of fast execution speed and high security.

CGI-based attack (CGI-based attack), which uses the vulnerabilities of public gateway interfaces to attack, usually through www sites.

The crash (crash) system suddenly becomes invalid and requires a new boot.

Data-driven attack (data-driven attacks) relies on attacks that hide or encapsulate data, and the data is not noticed through the firewall.

DNS spoofing (Domain Name Server electronic spoofing) attackers use to damage the Domain Name Server, a method that can be achieved by spoofing the DNS's high-speed cache or internal attacks (generally, attackers pretend to be legitimate DNS server roles)

DoS (hey, it's not DOS, it's deniad of service, it's a massive Denial of service) when a user maliciously uses the network information server, it will refuse to provide services to legitimate users.
