Question
1 Assume you are responsible for setting up security for an existing bank; they are upgrading all their equipment including setting up new security. Assume they have both a LAN and a WAN in place. Discuss in detail what would need to be in the security policy.
2 Discuss the needs of a small business network and identify small business network equipment requirements.
Identify small business application requirements.
Discuss a real world situation and what would be required with respect to #1 and 2 above.
Explanation / Answer
Answer:
1)
Security policies establish a framework within which to work, but they are too general to be of much use to individuals responsible for implementing these policies. Because of this, other, more-detailed documents exist. Among the more important of these detailed documents are the standards, guidelines, and procedures documents.
Whereas policy documents are very much high-level overview documents, the standards, guidelines, and procedures documents are documents that the security staff will use regularly to implement the security policies.
Standards
Standards enable an IT staff to be consistent. They specify the use of specific technologies so that IT staff members can narrow the focus of their expertise to those technologies instead of trying to know everything about all sorts of technologies. Standards also try to provide consistency in the network, because supporting multiple versions of hardware and software is unreasonable unless it is necessary. The most successful IT organizations have standards to improve efficiency and to keep things as simple as possible.
Standardization also applies to security. One of the most important security principles is consistency. If you support 100 routers, it is important that you configure all 100 routers as similarly as possible. If you do not do this, it is difficult to maintain security. When you do not strive for the simplest of solutions, you usually fail in being secure.
Guidelines
Guidelines help provide a list of suggestions on how you can do things better. Guidelines are similar to standards, but are more flexible and are not usually mandatory.
2)
Uncover your small business's requirements for performance, capacity and network ports. Meet with co-workers from each area of your company to understand their application and potential expansion requirements. Local area networks support a single location, like an office or building, using switches that provide ports to connect servers, storage hardware, computers, phones and printers to the network. The LAN itself consists of cabling, switches and routers that provide connectivity to the Internet as well as additional locations, if required, and routing between LAN segments.
Plan and design the cable layout. Cabling plays an important part of network design as it provides the physical communication path for your manufacturing company. Consult with a cable design professional experienced in manufacturing areas to minimize the potential for equipment interference. Consulting with a cable company provides peace of mind that you've planned the correct type of cable and included fire code specifications.
