Since the discussion of networking often includes talk of “?extra layers”?, this paper will address these unofficial layers as well. Finally, this paper will draw comparisons between the theoretical OSI model and the functional TCP/IP model. Although TCP/IP has been used for network communications before the adoption of the OSI model, it supports the same functions and features in a differently layered arrangement. An Overview of the OSI Model

This multi layered security plan will provide a brief overview the strategies to be implemented to each level of the information technology infrastructure. The IT infrastructure consist of seven domains User, Workstation, LAN, WAN, LAN-to-WAN, Remote Access, and Systems/Applications. However, we are going to outline the five we feel would be the most important for our beginning stage mitigating potential attacks. I) User Domain – Employees accessing the organization’s information system.

David Girten Jr 05 Aug 2013 Multi-Layered Security Plan for Richman Investments User Domain: Main concern at this domain is lack of user knowledge on what different attacks look like and proper response protocols. Here are a few solutions: A) Training: send emails on security best practices; alerts on common and new attack vectors; hold company-wide training segmented throughout the day; place Infosec, Opsec posters and incident response procedures in every space B) Auditing of user activity:

address is used mostly for identifying and sending information to hosts that are on the same network, or Ethernet. If you need to connect to a device on a network outside of your home or business network, however, you will need the logical address (or TCP/IP address). The example that was given in a book excerpt on informit.com was extremely helpful for me to understand the concept of network addressing. In Barry Press’ book, “Networking by Example”, he uses the example of finding a specific house
