between historical and statistical logging. There are several types of logs that can be kept, each providing different data that can be analyzed to provide information on potential ways of improving security over time. Local area networks (LANs which connect computers separated by short distances, such as in an office or a university campus, commonly use bus, star, or ring topologies. With symmetric keys, both the sender and the receiver use the same secret key for encryption and decryption. This insures that users cannot overwrite or delete files. Individual computers can each have their personal firewall for filtering data. File security protects the integrity of the files and provides version controlling on files and documents. In essays on blindness by jose saramago order to develop a complete and comprehensive security policy, it is first necessary to have a complete and comprehensive understanding of your network resources and their uses. It also prevents collisions due to simultaneous transmission that would waste media capacity. Logical connections are created by network protocols and allow data sharing between applications on different types of computers, such as an Apple Macintosh and an International Business Machines Corporation (IBM) personal computer (PC in a network.

The bus topology is composed of a single link connected to many computers. In the following paragraphs, I will try to explain the differences between some of the methods used. This might be the gateway separating a network from the outside world or an internal router on the network. Explain the difference between file security and firewalls. Firewalls provide a barrier between internal networks and the outside world. Others may have full writing and editing rights. The ring topology uses multiple links to form a circle of computers. Media, the medium used to transmit information limits the speed of the network, the effective distance between computers, and the network topology.

Network management and system administration are critical for a complex system of interconnected computers and resources to remain operating. These protocols are carried out by sending and receiving formatted instructions of data called packets. Advanced firewalls employ stateful packet filtering to prevent several types of undesired communications. Client computers send requests for information or requests to use resources to other computers, called servers, that control data and applications. The issue comes in deciding what services are needed and by whom, and thus which ports should be open and which should be closed. On the network security threats that exist with our current network design.
