NETWORK Computer Network also called Network is a group of computers and other devices connected to each other to share resources electronically. Networks can be as small as two computers or many thousand computers that are connected to one another. These computers are usually connected to one another through wires‚ satellite‚ and modems. Each device connected to the network is called a “node”‚ and the computer that is connected to the network is called a workstation. There are several ways

Problems with Formal Networks Formal networks are defined‚ setup and maintained by the organization. They are put into place to make sure information‚ resources‚ problems and punishments are used efficiently and not abused. When these networks are used properly everything will flow up and down the chain of command smoothly. This chain of command comes from the basic principle of a formal network; assigning titles to employees and to give them a certain amount of responsibility to go along with

in the protection of assets. No computer system or network achieves perfect security; even a system switched off with its hard drive removed sunken in a lead case in the bottom of a deep pool in an underground facility lacks security‚ as it guarantees integrity and confidentiality but completely sacrifices availability. As a security professional‚ you must understand the risks a network faces; you must‚ in essence‚ know how to bring the network down‚ to steal the data you want‚ and to falsify important

Network Security Some DoS attacks can be avoided by applying vendor patches to the software that has been compromised. Another way to deal with DoS attacks in the case of an attack coming from a number of known IP addresses is to put up a rule to drop all incoming traffic from those known attackers. Yet another way to deal with these types of attacks is to set up packet filters. This will act as a proxy for connections. Once the handshake is validated it will be forwarded to the correct destination

The actual school is much larger; we are only representing a subset of all the situations‚ and there are many more types of links and many more types of objects that might be used. An object diagram can be paraphrased in a natural language. Here is a description that can be deducted from the above object
