Introduction

Network defenses rely first on understanding the current configuration of hosts, services, and protocols in use within the organization. Before it is possible to plan to change anything, you must first understand what is present and where it is located within the network. The initial phase of any network security realignment process involves identifying existing resources.

Scenario

You have been working as a technology associate in the information systems department at Corporation Techs. The Corporation Techs’ management is concerned that they are losing business to a competitor whose bids are too accurately just under the bids offered by Corporation Techs––by an exact amount. A security firm was contracted to conduct a review of Corporation Techs’ systems, identifying unauthorized access to the Web server as a potential source of compromise due to the shared reporting and public Web site functions. The packet trace and vulnerability scans gathered during this review are available for your use.

The Web server provides public access to the organization’s static Web site for contact information, while sales team members in the field transfer contract and bid documents using a site secured with a logon and password. Corporation Techs has budgeted for new networking hardware but does not want to add additional servers due to cooling issues. Your manager has asked you to create a security plan that will prevent unauthorized access, while making sure that both public and secured Web access remain available.

Tasks

The data and information you need to complete this part of the project are provided in the Project Files folder. In this part of the project, you need to conduct a survey of the existing hosts, services, and protocols within Corporation Techs’ network. Specifically, you need to:

1. Access the PCAP data using NetWitness Investigator or Wireshark.
2. Identify hosts within the Corporation Techs’ network.
3. Identify protocols in use within the Corporation Techs’ network.
4. Develop a list of hosts and services provided by each.
5. Create a spreadsheet identifying the information above to help you design a network in the next section.
6. Submit spreadsheet outlining the network survey results as detailed in the instructions above.
