Networks are a vital part of modern society, and it is important to know how they work. The purpose of this presentation is to give you a basic understanding of packet analysis to enable you to response to the question:
“What’s happening on the network?”
· Understand the elements of packet analysis and network traffic flows.
· How to set up useful Wireshark interface views and settings.
· Determine what capture methods and filters to use.
· How to apply display filters.
· How to color code and export key packets.
· Building and interpreting tables and graphs.
· Speed up packet analysis by reassembling traffic.
· Adding comments to trace files and packets.
· Use of command line tools to capture, split, and merge traffic.
The first time you use a packet analyzer such as Wireshark, you will realize there are a dizzying array and abundance of packets, and you will be very will served knowing the basics of network packet analysis. Wireshark is a tool that can slice and dice the myriad packets into human useable information for you to know “What’s happening on the network?”.
During the 1970’s, John Green specialized in the design, implementation and sale of Plant Interlock and Safety Shutdown Systems for the chemical and petrochemical industry. At that time, safety shutdown systems were analog. With the advent of Programmable Controllers by Allen Bradley and others, it became cost effective to use off-the-shelf components to compete with Peabody Engineering, Brown and Root, and OEM equipment and system manufacturers such as Honeywell, Electronics Corporation of America, Rockwell and others.
Beginning in 1979, John Green ran a communications interconnect company based on DEC mini computers for the mid-size businesses phone system market during the Ma Bell breakup years. In 1983 he founded Nova Business Systems, Inc., an Oregon corporation, to provide the benefits of Relational Database application development to Small Medium Businesses using Digital Equipment Corporation mini-computers and multi-user operating systems where he was responsible for the design, implementation and support of Pascal based double entry bookkeeping software including custom modules for Job Costing, MRP & Scheduling, and related small business accounting and costing needs. By the end of the 80’s, Personal Computing had reached the point where mini-computers where replaced by Personal Computers and dumb terminals for multi-user business use. This evolved into Nova utilizing Unix based PC’s running client-server applications on high end PC platforms.
Today, Nova Business Systems, Inc. is a provider of business computer network security products and services including endpoint protection from Ransomware, exploits and malware; Unified Threat Management firewalls, secure Wi-Fi and VPN systems; strategic server backup and business continuity; Microsoft, LINUX, and UNIX system administration, and related services. Located in Lake Oswego, Oregon, we have been providing technical multi-user software solutions and services to Portland area businesses for over 35 years. “Since 1983”
