Understand Network Information for Forensic Investigation

Leave a Comment / CHFI / By

Understand Network Information for Forensic Investigation in this Sometimes when intruders gain remote access to a system, they try to find the other systems connected to the network and visible to the compromised system. To achieve this, the intruders create and execute batch files in the system and launch net view commands via SQL injection (by using a browser to send commands to the system through the web and database servers). When the users establish …

Learn how to do Error Recovery and Reliability

Leave a Comment / CCNA / By

Learn how to do Error Recovery and Reliability in this TCP provides for reliable data transfer, which is additionally called reliability or error recovery, counting on what document you read. To accomplish reliability, TCP numbers data bytes using the Sequence and Acknowledgment fields within the TCP header. TCP achieves reliability in both directions, using the Sequence Number field of 1 direction combined with the Acknowledgment field within the opposite direction. Figure 5-7 shows an example …

Introduction to TCP and UDP

Leave a Comment / CCNA / By

Introduction to TCP and UDP in the OSI transport layer (Layer 4) defines several functions, the most important of which are error recovery and flow control. Likewise, the TCP/IP transport layer protocols also implement these same sorts of features. Note that both the OSI model and the TCP/IP model call this layer the transport layer. But as was common , when pertaining to the TCP/IP model, the layer name and number are supported OSI, so …

Overview of Network Layer Functions

Leave a Comment / CCNA / By

Overview of Network Layer Functions Many protocol models have existed over the years, but today the TCP/IP model dominates. And at the network layer of TCP/IP, two options exist for the most protocol around which all other network layer functions revolve: IP version 4 (IPv4) and IP version 6 (IPv6). Both IPv4 and IPv6 define the same sorts of network layer functions, but with different details. This chapter introduces these network layer functions for IPv4, …

Introduction of OSI Networking Model this blog is written on OSI Networking Model with it’s layer description as well as function and compared OSI with TCP/IP model. OSI Networking Model At one point within the history of the OSI model, many of us thought that OSI would win the battle of the networking models discussed earlier. If that had occurred, rather than running TCP/IP on every computer within the world, those computers would be running …

This blog is on TCP/IP networking model in that Overview has given as well as there different layer has been explained. Overview The TCP/IP model both defines and references a large collection of protocols that allow computers to communicate. To define a protocol, TCP/IP uses documents called Requests For Comments (RFC). (You can find these RFCs using any online search engine.) The TCP/IP model also avoids repeating work already done by another standards body or …
