Questions On Http And Ftp

The Hypertext Transfer Protocol (HTTP) is an application protocol for distributed, collaborative, hypermedia information systems.[1] HTTP is the foundation of data communication for the World Wide Web.

Many of the documents are transferable from the Internet using a member of the TCP/IP family called:

data has to be, and what pieces of software computers need to have to send this kind of data.

A web server is computers otherwise gathering of computers that are used to deliver a web pages and other information to multiple users within the server.

type and operating system used so that the File System Server can supply files to any type of

Https is not really a protocol by itself instead it is the result of running the protocol (http) on top of two other protocols called ssl/tls. This makes internet communication more secure. It also ensures that in data within the internet communication from the user and the website cannot be read or breached by a third party.

19. Which protocol does a web server use when transmissions are encrypted for security? HTTPS  (HTTP secure)

Web Server – It is where webpages are stored and accessed by computers from. It also stores the documents that are on the webpages.

TCP/IP stands for transmission control protocol/ internet protocol. TCP/IP is responsible for how devices like computers should be connected over the internet and how data should be transmitted from one computer to another. The IP essentially functions by exchanging set of information which is called packets. Packets are short structures of bytes which contains of headers and body. The body only contains the application data. The headers keep on sending the information back on forth until the data is sent to the right destination, the packets can usually send in the wrong order this means that the data was crashed by the firewall or data was destroyed while sending information.TCP is the transmission communication protocol which delivers packets to the accurate to destination.

A Web server: is a computer system that processes requests over HTTP, the default network protocol used to distribute information over the World Wide Web. This term can refer to the entire system or software that accepts and supervises HTTP requests.

it defeats all known firewalls, killing the running process, replacing the firewall icon, and allowing a stealth FTP connection. The D.I.R.T. client can be embedded in Word documents, Excel documents, PowerPoint presentations, RTF documents,

A possible vulnerability for a server is a brute-force attack through the FTP service. Accounts used for FTP are physical user accounts on the host operating system, theoretically it is possible to guess the administrator username one you have determined the FTP server type. Once a user account has been discovered, a malicious client can connect to a server and attempt a brute-force attack on the account. IIS 7.5 the FTP service introduced extensibility APIs that granted developers to create custom authentication providers, which allows non-Windows accounts access to FTP. This reduces the surface attack area significantly for the FTP service because these FTP accounts are not valid Windows accounts, and so have no access to resources outside the FTP service.

A file server provides a central location on your network where you can store and share files with clients across the local network. When users require an important file, they can access the file on the file server instead of having to pass the file between their separate computers. If the clients need access to the same files and network accessible applications, configure this computer as a file server.

Packet filtering is the earliest technology developed to protect the network from dangers in the Internet. It works at network transport layer. A data is split in to several packets and then reassembled back once it has reached its destination. Administrators creates a set of rules which will then be configured to the router, router will then act as a security guard, will either deny or allow packets from passing through. However packet filtering has only limited function, it can only analyze header information in IP packets. For an instance it can all allow or deny specific functions of FTP such as the use of “GET” and “PUT” command (Ogletree, 2000). Packet filtering susceptible to IP Spoofing (Webopedia, 2011). IP Spoofing is used by

A protocol is most simply defined as a standard. These standards define how computers are able to communicate with each other. These standards are defined in documents called Request for Comments( RFC ) which is a formal document from an organization known as the Internet Engineering Task Force( IETF ). These documents are made publicly available so that any program that needs to use these protocols are able to configure them properly so that it works with all other programs that make use of the same protocol. There are thousands of protocols that exist and many of them are very common and others are very seldom used. Some of the most common protocols are HTTP/HTTPS, FTP, SMTP, IMAP, POP3, SSH and DNS. Many of these are used almost every
