Practical Connection: Network Survey

Practical Connection: Network Survey

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 to you. (See the Required Source Information and  Tools section at the beginning of this document.) 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.
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 professional report detailing the information above as  the initial document for development of the network security plan.

Write the network survey results as detailed in the instructions above.
