This document defines and describes several internet protocols: HTTP is used for distributing multimedia over the internet. HTTPS provides secure communication over networks using HTTP. SSH enables secure data transfer and remote access. POP3 downloads email from servers to computers. NTP synchronizes computer clock times in a network using UTC. SSL manages secure message communication. SMS allows the exchange of short text messages between phones or other devices using standard protocols.
SSH is a protocol for secure remote access to a machine over untrusted networks.
SSH is a replacement for telnet, rsh, rlogin and can replace ftp.
Uses Encryption.
SSH is not a shell like Unix Bourne shell and C shell (wildcard expansion and command interpreter)
A Denial-of-Service (DoS) attack shuts down a machine or a network to make it inaccessible to its intended users. This PPT sheds light upon this kind of a cyberattack and its types, to increase awareness related to the threat that it poses to web servers and applications.

TCP - TCP breaks data into manageable packets and tracks information.pdfanjanacottonmills
TCP - TCP breaks data into manageable packets and tracks information such as source and
destination of packets. It is able to reroute packets and is responsible for guaranteed delivery of
the data.
IP - This is a connectionless protocol, which means that a session is not created before sending
data. IP is responsible for addressing and routing of packets between computers. It does not
guarantee delivery and does not give acknowledgement of packets that are lost or sent out of
order as this is the responsibility of higher layer protocols such as TCP.
UDP - A connectionless, datagram service that provides an unreliable, best-effort delivery.
ICMP - Internet Control Message Protocol enables systems on a TCP/IP network to share status
and error information such as with the use of PING and TRACERT utilities.
SMTP - Used to reliably send and receive mail over the Internet.
FTP - File transfer protocol is used for transferring files between remote systems. Must resolve
host name to IP address to establish communication. It is connection oriented (i.e. verifies that
packets reach destination).
TFTP - Same as FTP but not connection oriented.
ARP - provides IP-address to MAC address resolution for IP packets. A MAC address is your
computer\'s unique hardware number and appears in the form 00-A0-F1-27-64-E1 (for example).
Each computer stores an ARP cache of other computers ARP-IP combinations.
POP3 - Post Office Protocol. A POP3 mail server holds mail until the workstation is ready to
receive it.
IMAP - Like POP3, Internet Message Access Protocol is a standard protocol for accessing e-
mail from your local server. IMAP (the latest version is IMAP4) is a client/server protocol in
which e-mail is received and held for you by your Internet server.
TELNET - Provides a virtual terminal or remote login across the network that is connection-
based. The remote server must be running a Telnet service for clients to connect.
HTTP - The Hypertext Transfer Protocol is the set of rules for exchanging files (text, graphic
images, sound, video, and other multimedia files) on the World Wide Web. It is the protocol
controlling the transfer and addressing of HTTP requests and responses.
HTTPS - Signifies that a web page is using the Secure Sockets Layer (SSL) protocol and is
providing a secure connection. This is used for secure internet business transactions.
NTP - Network Time Protocol is a protocol that is used to synchronize computer clock times in
a network of computers.
SNMP - Stands for Simple Network Management Protocol and is used for monitoring and status
information on a network. SNMP can be used to monitor any device that is SNMP capable and
this can include computers, printers, routers, servers, gateways and many more using agents on
the target systems. The agents report information back to the management systems by the use of
“traps” which capture snapshot data of the system. This trap information could be system errors,
resource information, or other info.

Layers
protocol:-A protocol is a set of rules for the exchange of data between a terminal and computer or between two computers. Think of protocol as a sort of recommunication agreement about the form in which a message or data is to be sent and receipt is to be acknowledge.
transmission control protocol(TCP):-This protocol ensures the delivery of information packets across network.
internet protocol (IP):-This important protocol is responsible for providing logical addressing called IP address to route information between networks.
hyper text transfer protocol (HTTP):- This protocol is used to access, send and receive Hypertext Markup Language (HTML) files on the Internet.
simple mail transfer protocol(SMTP):-This protocol is used for transferring email between computers.
file transfer protocol(FTP):-FTP is responsible for allowing file to be copied between devices.
layers:-In computer programming, layering is the organization of programming into separate functional components that interact in some sequential and hierarchical way, with each layer usually having an interface only to the layer above it and the layer below it.

4. SSH
Secure Shell (SSH) is a coded network protocol
for secure data communication, remote
command-line login, remote command
execution.
5. POP3
A protocol for receiving e-mail by downloading it
to your computer from a mailbox on the server
of an Internet service provider.
6. NTP
Network Time Protocol (NTP) is a protocol that
is used to synchronize computer clock times in a
network of computers. NTP uses Coordinated
Universal Time (UTC) to synchronize computer
clock times to a millisecond, and sometimes to a
fraction of a millisecond.
7. SSL
Secure Sockets Layer (SSL) is a commonly-used
protocol for managing the security of a message
communication on the Internet.
8. SMS
Short Message Service (SMS) is a text messaging
service component of phone, Web, or mobile
communication systems. It uses standardized
communications protocols to allow fixed line or
mobile phone devices to exchange short text
messages.
