Physical Threats Threats can come from many sources and can affect different parts of a system and network. There are physical threats that can compromise a system and deny the use of network resources. Damage can occur on any hardware components connected to the system such as servers, routers, switches and workstations/PCs. Access should be controlled to where vital hardware is stored. Make sure that all doors remain closed and that only authorized people access restricted areas. There can also be damage caused by electrical threats. A voltage spike or total loss of power can shut down critical systems and cause negative impacts throughout your business. The APC Smart-UPS RT 5000VA 230V will continue to provide emergency power to existing stores and new stores. Server rooms will remain environmentally controlled to avoid extreme temperatures. Store policies should address maintenance issues of all network equipment to avoid problems later. Network Threats Threats can occur on a network regardless of type, whether wired or wireless. Providing adequate network security should ensure minimal disruptions. Network threats can be divided into four classes to include: structured threats, unstructured threats, internal threats, and external threats. Structured threats usually come from individuals who have extensive knowledge of computer systems. These expert hackers will attempt to extract information, commit fraud, and destroy or alter records on the targeted network. They will use any means possible to gather information about online systems, including phishing, pharming and spoofing. Making company employees aware of these tactics can help prevent them from revealing vital information... middle of paper... affecting the speed of networks and connected devices. Three types of wiring are commonly used; coaxial, twisted pair and fiber optic. Each has its advantages and disadvantages. Kudler Fine Foods has a twisted-pair or 100BaseT LAN that uses Cat-5 cables. This has the amount of speed needed for the network to function. The connection between the shops takes place via dedicated T3 lines via coaxial cable with a speed of 44.736 Mbit/s. There is also a dedicated OC-1 line that connects the home office to each store. This line is a SONET line with transmission speeds of up to 51.84 Mbit/s. Conclusion A network faces physical and network threats that disrupt or compromise system resources. Preventive measures are used to protect company assets. A network has many building blocks associated with it, each element can influence how the network functions and how it is protected.
