Company Security - Essay Example The needs of users of  the data provided via a network and subsequently develop a security policy and plan that addresses the security issues concerned (Langer, 2001). The ensuing distribution of data in client or server networks leads to increased susceptibility of the system to fraud, damage by malicious software, misuse, as well as physical damage. With business organizations and their stakeholders developing complex networks, security issues become a key factor of consideration. The security systems developed by such organizations must seek to protect all areas of concern across the network to prevent the occurrence of unethical practices in relation to the information flowing through the system. The value of security in a client/server network plays an inevitable role in protecting the data, as well as the ethical concerns of the parties involved thus, requiring the development of a comprehensive network security policy as reviewed in this context and with reference to ZXY Cor poration. In order to enhance secure access control over the network, the company can apply advanced authorization, as well as access control methodologies that would subsequently enhance network security. The interrelated methods of user authentication and authorization that are applicable will depend on the sensitivity of the section of the network and the information that may be accessible. Shared resources in the network are available for all the users except the resource owner. As such, the security system needs to protect such information from unauthorized access and use. In the network’s access control framework, unique security identifiers (SIDs) may embody the users in the system, and they are subsequently assigned permissions and rights that provide information to the operating system concerning what each of the users can do in the system. Each of the resources in the network has a designated owner who grants  permission  to users. In

Several Topics(Psychology 101) - Essay Example Storage of information can be systematically done by conscious process of learning either in formal or non-formal ways. Memory or information gained by the learner through this process is referred to as declarative memory. Learning through proper study or experience, and other similar approaches are included in this category. It can be semantic or episodic. Semantic declarative memories are memories of meanings, understandings, and other concept-based knowledge without the help of experience. For instance knowing that a hammer is a tool and not a pet is a semantic memory. In the other hand episodic declarative memory are knowledge of events, times, places, associated emotions, and others learning, in relation to an experience. Declarative memories are otherwise called as explicit memory Procedural memory or implicit memory in the other hand are knowledge and information gained stored and retained through past experience of events, places, times, emotions, and other learning activities that are used by the learners unconsciously in the process of doing things. Mastery in driving is developed unconsciously by previous experiences without the driver being conscious of what had been learned from the past. Survival instincts are considered as implicit or procedural memory. Procedural memories are information and memories learned through time used procedural works. In dealing with daily chores both explicit and implicit knowledge are useful in making hard tasks easy. This information intertwines with each other in our dealings with other people, solving our problems, doing our jobs, deciding what is best, and determining which is right and wrong. 2. Short and Long Term Memory The brain collects and stores information in the course of daily activities as humans are faced with varying circumstances every second and decides whether this information is useful and subject for further refining and re-storage for future use or discards it after the event ceased. These bits of data are short-term memories with the potential of becoming long-term memories. Short-term memories are commonly called primary, working, or active memory. They are stored in the brain for about 30 seconds and are used in the current process of analyzing the current stimuli or situation. These memories in small "bytes" are combined with each other to form into another information which maybe stored as another short term information or stored for longer time for future use. Once that particular event has been completed some less useful memory are lost and useful ones are retained as long-term memory. And the process goes on and on and on. Long-term memories (LTM) are data stored in the brain for 30 seconds or as long as decades. Short-term memories which are used by the brain further become LTMs. Retention of memory is accomplished through the process of rehearsal or continued use and meaningful association with established long term memories. The meaning of red traffic light can be forgotten fast if it is not associated with traffic rules. By this example a short-term memory became a long-term memory. The mechanism involved in converting short-term memories into LTM is called long-term potentiation. Just like short term memories, long-term memory is also subject to forgetting process, several retrieval processes may be needed for them to last longer. Chunks of information flood into the brain every second in our dealings with a lot of stimuli. Some of these memories do not last long and are called short-term
