¶ … competitive, fast-paced business world, a network failure can be disastrous. The pressure placed on network administrators to fix issues immediately is daunting; these important players need all the tools they can get to troubleshoot, prevent, and repair problems. Network administrators must remain vigilant and work constantly to monitor for interface or host failures, detect route flapping or intrusions, perform LAN segment switches or bandwidth adjustments, and monitoring overall performance for Service Level Agreements (SLAs). The International Organization for Standardization (ISO) has grouped these tasks into five main management categories: performance, fault, configuration, accounting, and security. Successful network administration across these categories requires sophisticated tools and technology, and as with other aspects of computer networking, network administration is based on protocols. The most popular network management protocol in place today is the Internet SNMP (Simple Network Management Protocol), although this standard is far from simple. In fact, this protocol is just one aspect of the overall management operation. Also known as the Internet-Standard Management Framework, the overall operation is based on four main components: the Management Information Base (MIB) objects and modules, the SMI (Structure of Management Information) data definition language, the SNMP protocol, and security and administration capabilities. (Kurose and Ross) Staying on top of so many important operations is a daunting task even for seasoned administrators, and the demand for these talented professionals is growing. The question is: how do they do it? This essay will explore in more detail what takes place during the day of a network administrator, suggest ways to increase the number of students choosing network administration as a career,...
Apparently, the stress of the job is such that this important breed of computer scientists is eager to vent and share their experiences. Overall, from reading these accounts, it appears that a typical network administrator works anywhere from 8 to 16 hours a day, with responsibilities including the following:
Another aspect of the security management area of a network management system is the development of policy-based auditing and alerts by role in the organization (Merilainen, Lemmetyinen, 2011). This is one of the areas of knowledge-enabled security management, specifically in the area of role-based access and advanced auditing and reporting. Fault management is also an area that no single suite of network management systems can completely meet per the ISO standards
Network Management and System Administration The aim of the paper is to establish the difference between a system administrator and a network administrator. The paper is thus divided into three sections. The first section deals with the basic definition and responsibilities of a system administrator; the second does the same for a network administrator and the third compares their responsibilities to clearly identify the differences between the two. System Administrator The maintenance of
). Such security should also preplan strategic responses to attacks associated with the network (Dawkins et al.). A book entitled "Surviving Security: How to Integrate People, Process, and Technology" explains that the rapid expansion networking and networking technologies necessitates greater security needs. The author asserts that parts of the network such as routers, switches and even network printers are vulnerable (Andress). The article further explains that the router or switch contained
Network Design The process of gathering technical requirements for a network design project may differ from one organization to another, but the requirements themselves can be described using many of the concepts discussed in the lecture this week (i.e. Scalability, Availability, Network performance, Security, Manageability, and Affordability). Analyzing technical requirements for the customer is important in helping one best fulfill the customer's expectations. The various objectives that need to be fulfilled involve
