Project Part 1: Network Survey Introduction And Network Defe

Project Part 1 Network Surveyintroductionnetwork Defenses Rely First

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.

Paper For Above instruction

Effective network security relies on a comprehensive understanding of existing network configurations, including hosts, services, and protocols. For Corporation Techs, this foundational assessment involves a systematic analysis of network traffic captured in PCAP files, utilizing tools such as NetWitness Investigator. This process enables the identification of all active hosts, the services they provide, and the protocols in use, forming the basis for subsequent security planning.

The first step involves accessing the PCAP data using NetWitness Investigator to parse the raw packet captures efficiently. This tool allows for deep inspection of network traffic, revealing communication patterns, protocol usage, and device behaviors. By filtering and analyzing the packet traces, one can discern all hosts present within the network, whether they are servers, workstations, or network infrastructure devices.

Identifying hosts within the network involves examining source and destination IP addresses, port usage, and traffic volumes. It is crucial to distinguish between authorized resources—such as the web server providing public access and internal services—and any unknown or unauthorized devices that may have gained access. The analysis should produce a comprehensive list of all identified hosts, cross-referenced with their roles and functions within the organization.

In addition, understanding the protocols in use provides insights into both legitimate and potentially vulnerable network activities. Common protocols like HTTP, HTTPS, FTP, SSH, SMTP, and DNS should be cataloged, including any anomalies or unusual behaviors that might suggest misconfigurations or security risks. For instance, the detection of unencrypted transfers or unexpected protocol use could highlight vulnerabilities that need addressing.

Developing a detailed list of hosts and services involves compiling data on each discovered device, including IP addresses, device types, running services, and open ports. This inventory forms the critical input for risk assessment and security planning. It allows for targeted monitoring, vulnerability testing, and the development of network segmentation strategies.

Finally, the report should be professionally formatted, clearly presenting the findings and emphasizing their implications for security. It should include an executive summary, detailed asset enumeration, protocol mapping, and recommendations for future security enhancements. The report serves as the foundation for designing an effective security plan that minimizes risks while maintaining necessary operational functionalities.
