Designing a Secure Local Area Network In order to design and build a well-secured network, many factors must be taken into consideration, such as the topology and placement of hosts within the network, the selection of hardware and software technologies, and the careful configuration of each component. My paper will be an examination of some of the issues in designing a secure Local Area Network (LAN) and some of the best practices suggested by security experts. I will discuss securing a LAN from the viewpoint of the network architect considering three main areas: the network topology which comprises the physical and logical design of the network; securing the routers and switches which connect segments and hosts to form the network; and, finally, some of the emerging and advanced techniques in network security will be examined.

J.D. Edwards Security using RBAC By using a variation of a Role-Based Access Control (RBAC) model and adhering to its principles, we were able to provide a quality security definition that met our business needs. The business needs were essentially to follow the CIA definition of security and be flexible enough to provide a granular solution. Confidentiality, integrity and availability requirements led to various security rules to prevent all user access unless specifically granted. Our logical security roles helped provide a granular solution by separating the users’ duties into small groups. Even with challenges and obstacles the implementation has been successful.

Securing the Network in a K-12 Public School Environment A K-12 school environment presents special needs and requirements, it goes beyond the obvious items such as physical security, routers, sub-netting, firewalls, and anti-virus. These will be addressed as well, but we will be looking at several other very important issues, which include privacy (confidentiality), data integrity, and content filtering.
