The document discusses the TCP/IP protocol suite. It is made up of several protocols that implement the four-layer hierarchy model, including the Transmission Control Protocol (TCP) and Internet Protocol (IP). TCP establishes connections between hosts and provides reliable transmission, while the User Datagram Protocol (UDP) does not establish connections and is unreliable but more efficient for applications like DNS lookups. The document also compares key differences between TCP and UDP and describes the role of IP in network layer packet forwarding and routing.

TCP RFC 793 TCPIP (Transmission Control ProtocolInternet Proto.pdf
TCP : RFC 793
TCP/IP (Transmission Control Protocol/Internet Protocol) is the basic communication language
or protocol of the Internet. It can also be used as a communications protocol in a private network
(either an intranet or an extranet). When you are set up with direct access to the Internet, your
computer is provided with a copy of the TCP/IP program just as every other computer that you
may send messages to or get information from also has a copy of TCP/IP.
UDP: RFC 768
UDP (User Datagram Protocol) is an alternative communications protocol to Transmission
Control Protocol (TCP) used primarily for establishing low-latency and loss tolerating
connections between applications on the Internet. Both UDP and TCP run on top of the Internet
Protocol (IP) and are sometimes referred to as UDP/IP or TCP/IP. Both protocols send short
packets of data, called datagrams.
UDP provides two services not provided by the IP layer. It provides port numbers to help
distinguish different user requests and, optionally, a checksum capability to verify that the data
arrived intact.
IPv4: RFC 791
Internet Protocol being a layer-3 protocol (OSI) takes data Segments from layer-4 (Transport)
and divides it into packets. IP packet encapsulates data unit received from above layer and add to
its own header information.
IPv4 is a connectionless protocol for use on packet-switched networks. It operates on a best
effort delivery model, in that it does not guarantee delivery, nor does it assure proper sequencing
or avoidance of duplicate delivery. These aspects, including data integrity, are addressed by an
upper layer transport protocol, such as the Transmission Control Protocol (TCP).
IPv6 : RFC 2460
IPv6 (Internet Protocol version 6) is a set of specifications from the Internet Engineering Task
Force (IETF) that\'s essentially an upgrade of IP version 4 (IPv4). The basics of IPv6 are similar
to those of IPv4 -- devices can use IPv6 as source and destination addresses to pass packets over
a network, and tools like ping work for network testing as they do in IPv4, with some slight
variations.
The most obvious improvement in IPv6 over IPv4 is that IP addresses are lengthened from 32
bits to 128 bits. This extension anticipates considerable future growth of the Internet and
provides relief for what was perceived as an impending shortage of network addresses. IPv6 also
supports auto-configuration to help correct most of the shortcomings in version 4, and it has
integrated security and mobility features.
HTTP : RFC 1945
HTTP (Hypertext Transfer Protocol) is the set of rules for transferring files (text, graphic
images, sound, video, and other multimedia files) on the World Wide Web. As soon as a Web
user opens their Web browser, the user is indirectly making use of HTTP. HTTP is an
application protocol that runs on top of the TCP/IP suite of protocols (the foundation protocols
for the Internet).
HTTP concepts include (as the Hypertext part of the name implies) the idea that .
Lecture 04
The document discusses the TCP/IP protocol suite, which is composed of four layers: physical/data link layer, network layer, transport layer, and application layer. The network layer uses IP and four supporting protocols to enable internetworking. The transport layer uses UDP for non-reliable delivery and TCP for reliable, connection-oriented delivery. TCP/IP addressing includes physical, IP, port, and special purpose addresses.
CCCNA R&S-02-The TCP-IP and OSI Networking Models
This document provides an overview of the TCP/IP and OSI networking models. It describes the layers of each model and the key protocols associated with each layer, such as IP, TCP, UDP, Ethernet, and HTTP. It also compares the two models and explains how they were developed with different purposes but provide similar functionality to define rules for network communication.
The TCP/IP and OSI models
This document provides an overview of the TCP/IP and OSI networking models, including:
1) Both models use a layered approach and were developed around the same time for standardizing network protocols, with TCP/IP focusing on practical implementation and OSI aiming for strict layering.
2) TCP/IP became the dominant model due to its flexibility and simplicity, while OSI provided a structured way to describe network functions.
3) Key protocols are mapped to their corresponding layers in each model, showing how they achieve similar communication goals with different approaches.
Ch4 Protocols.pptx
Protocols define the rules and format for how computers exchange information over a network. The key features of protocols include syntax, semantics, and timing. There are two main protocol models - the TCP/IP model and OSI reference model. TCP/IP is comprised of four layers including network access, internet, host-to-host transport, and application layers. The OSI model has seven layers and provides a framework for developing networking standards. Common protocols like TCP, IP, UDP, HTTP, FTP and SMTP control how different aspects of networking like file transfers, email, and web browsing function.
TCP/IP Modal
The document discusses TCP/IP (Transmission Control Protocol/Internet Protocol), which is a suite of communication protocols used to connect devices on the internet and private networks. It describes the history of TCP/IP's development by DARPA in the 1970s and its use in Unix operating systems. The document outlines the importance, uses, layers, and basic functioning of TCP/IP.
TCP/IP Model
The document discusses the layers of the TCP/IP protocol suite. It describes that TCP/IP was developed before the OSI model and that its layers do not exactly match those of OSI. The TCP/IP protocol suite is described as having either 4 or 5 layers. Each layer is defined by the unit of communication it uses - bits at the physical layer, frames at the data link layer, datagrams at the network layer, segments or packets at the transport layer, and messages at the application layer.
History of tcp
The document provides a history of the development of TCP/IP from its origins in research conducted by DARPA in the late 1960s through key milestones and protocols introduced through the 1990s. It discusses how TCP/IP became the standard protocol suite for the Internet and how its evolution is overseen by organizations like the IETF and RFC standards process. Key terms related to TCP/IP networking components like nodes, routers, hosts, interfaces and subnets are also defined.
Chapter04 -- network protocols
The document summarizes key network protocols including TCP/IP, IPX/SPX, NetBIOS, and AppleTalk. It describes the layers of the TCP/IP protocol suite and how they correspond to the OSI model. It also discusses important TCP/IP protocols like TCP, IP, UDP, ICMP, and ARP as well as addressing schemes, dynamic host configuration protocol (DHCP), and port numbers.
10. tcp ip and do d model
The document discusses the TCP/IP and DoD models. It explains that the DoD model has 4 layers instead of the 7 layers in the OSI model. The 4 layers are the Process/Application layer, Host-to-Host layer, Internet layer, and Network Access layer. It then provides details on protocols that operate at each of these layers, such as TCP and UDP at the Host-to-Host layer, and IP at the Internet layer.
DCN 5th ed. slides ch02-Network Models.pptx
The document provides an overview of network models, specifically discussing protocol layering, the TCP/IP protocol suite, and the OSI model. It describes the principles of protocol layering, including the need for bidirectional communication and identical objects between layers. It then explains the layered architecture of TCP/IP, describing each layer and concepts like encapsulation, addressing, and multiplexing. Finally, it compares TCP/IP to the OSI model, noting reasons the OSI model was not fully adopted, such as TCP/IP already being established and some OSI layers not being fully defined.

The document discusses the TCP/IP networking model and its layers. It explains that layered architectures allow components to interoperate flexibly through well-defined interfaces. The TCP/IP model uses TCP and IP as its main protocols and consists of four layers - application, transport, internet, and network access. The application layer enables standardized data exchange. The transport layer maintains end-to-end communications using TCP for reliability and UDP for special purposes. The internet layer deals with packet delivery across networks using IP and ICMP. The network access layer uses protocols like Ethernet and ARP that operate on a single link. The document also compares TCP/IP to the OSI model and concludes that while OSI is a guidance tool, TCP/IP will continue to
Why Ipv6 May Be Adopted Later Rather Than Sooner
This document discusses the transition from IPv4 to IPv6, comparing the key differences between the two protocols. IPv6 was developed to address limitations in IPv4, such as the limited number of available IPv4 addresses. Some of the improvements IPv6 offers over IPv4 include a larger address space, built-in security features, easier configuration, and support for new applications and technologies. While IPv6 is meant to eventually replace IPv4, a full transition will take time, and both protocols will coexist during the transition period.
Networking Fundamentals
This document provides an overview of networking concepts including:
- Networking refers to interconnecting two or more computers. Common network types include intranets, the internet, and extranets.
- Bandwidth refers to the maximum data transfer capacity of a network connection or line. Collision and broadcast domains describe how devices interact on a shared network medium.
- Common networking devices like bridges, hubs, switches, and routers are described along with their functions in managing data and network traffic.
- Popular networking protocols are defined including TCP/IP, FTP, TFTP, NFS, SNMP, DHCP and others. The OSI model and TCP/IP networking stacks are also summarized.
Internet Protocol(Samyak Jain 25014).pptx
The document discusses Internet Protocol (IP) which specifies the format of data packets and the addressing scheme used on networks. IP allows for addressing and dropping packets in the network system like a postal system, but does not directly connect the source and recipient. Most networks combine IP with Transmission Control Protocol (TCP) to establish a connection between hosts to send messages back and forth. Commonly used internet protocols include TCP/IP, FTP, and HTTP. IP addresses provide a unique global address for network interfaces and encode network and host numbers. While IPV4 is currently used, IPV6 is designed to replace it and provide more addresses and functionality for future internet growth.

The document also compares TCP/IP to the OSI model and concludes that while OSI is a guidance tool, TCP/IP will continue to
Why Ipv6 May Be Adopted Later Rather Than Sooner
This document discusses the transition from IPv4 to IPv6, comparing the key differences between the two protocols. IPv6 was developed to address limitations in IPv4, such as the limited number of available IPv4 addresses. Some of the improvements IPv6 offers over IPv4 include a larger address space, built-in security features, easier configuration, and support for new applications and technologies. While IPv6 is meant to eventually replace IPv4, a full transition will take time, and both protocols will coexist during the transition period.
Networking Fundamentals
This document provides an overview of networking concepts including:
- Networking refers to interconnecting two or more computers. Common network types include intranets, the internet, and extranets.
- Bandwidth refers to the maximum data transfer capacity of a network connection or line. Collision and broadcast domains describe how devices interact on a shared network medium.
- Common networking devices like bridges, hubs, switches, and routers are described along with their functions in managing data and network traffic.
- Popular networking protocols are defined including TCP/IP, FTP, TFTP, NFS, SNMP, DHCP and others. The OSI model and TCP/IP networking stacks are also summarized.
Internet Protocol(Samyak Jain 25014).pptx
The document discusses Internet Protocol (IP) which specifies the format of data packets and the addressing scheme used on networks. IP allows for addressing and dropping packets in the network system like a postal system, but does not directly connect the source and recipient. Most networks combine IP with Transmission Control Protocol (TCP) to establish a connection between hosts to send messages back and forth. Commonly used internet protocols include TCP/IP, FTP, and HTTP. IP addresses provide a unique global address for network interfaces and encode network and host numbers. While IPV4 is currently used, IPV6 is designed to replace it and provide more addresses and functionality for future internet growth.

HijackLoader Evolution: Interactive Process Hollowing
CrowdStrike researchers have identified a HijackLoader (aka IDAT Loader) sample that employs sophisticated evasion techniques to enhance the complexity of the threat. HijackLoader, an increasingly popular tool among adversaries for deploying additional payloads and tooling, continues to evolve as its developers experiment and enhance its capabilities.
In their analysis of a recent HijackLoader sample, CrowdStrike researchers discovered new techniques designed to increase the defense evasion capabilities of the loader. The malware developer used a standard process hollowing technique coupled with an additional trigger that was activated by the parent process writing to a pipe. This new approach, called "Interactive Process Hollowing", has the potential to make defense evasion stealthier.
