Memo - Essay Example I've prepared an analysis about the use of vulnerability assessment systems and intrusion detection systems in your company, just like you asked me. You specifically asked whether the use of both systems will be a waste of resources and a duplication of efforts. My analysis suggests that VAS and IDS have separate internal functions for the security of the computer systems and both must be a part of a computer system for complete security control. Vulnerability assessment systems are those security scanning tools that assess level of threat that can penetrate a system. The main job of such tools is to scan networks, servers, firewalls, routers, and applications and report system vulnerabilities. "Generally, the tools can detect known security flaws or bugs in software and hardware, determine if the systems are susceptible to known attacks and exploits, and search for system vulnerabilities such as settings contrary to established security policies". (Becker, 1999) New threats are discovered each day thus the vulnerability assessment tools must be updated regularly. Any new weaknesses such as security flaws and bugs would need to be patched in the system so that no holes left for malwares, viruses, spywares etc. to infect the system. Another feature of a vulnerability assessment system is that it generates reports which can tell a user what and where weaknesses exist and how to fix them. (Becker, 1999) Intrusion Detection Systems Vulnerability assessment is the first step in securing the system from threats by taking appropriate security precautions and patch-ups. However, new threats are raised everyday and some might pass through the vulnerability precautions. Therefore the next logical step is to "monitor the system for intrusions and unusual activities". Intrusion detection systems automatically raise the alarm in case of a security breach and inform the Computer Incident Respond Team for their help. "By analyzing the information generated by the systems being guarded, IDSs help determine if necessary safeguards are in place and are protecting the system as intended". Important to note here is that IDS don't protect the system, they just pinpoint the location of the attack and collect the information related to the attack and the attacker. (Becker, 1999) IDS tools are used by the CIRT to generate both technical and management reports since it provide background information on the type of attack and the attacker. IDS can also give recommendations to the management about the courses of action to take to seal the breach. (Becker, 1999) Example The difference can easily be understood by the following example. Vulnerability assessment just checks how susceptible a person is to catching a cold in winters. The vulnerabilities that the system can find is that not enough warm clothes are worn and heater is not being used. The intrusion detection system checks that cold air in hitting the person directly which may be harmful, and the point of intrusion was the chest of the person. So a person gets the information from the vulnerability system that he needs to have a heater and wear warm clothes and from the intrusion

A psychological and sociological perspective to demonstrate an Essay

A psychological and sociological perspective to demonstrate an understanding of these perspectives and evaluate in what way there application enhances your unde - Essay Example e lives; nevertheless, it is a fact that society has to accept single parenting, because in future, with present stress on individuality, more and more children are likely to be brought up by single parents. Parents who find themselves abandoned by partners are supported by social care and children, who will learn to react to the circumstances and environments, will find difficulties in dealing with social and psychological problems. According to the case study, Michael and Kate were having problems during her third pregnancy because of Michael’s attitude towards his family. He has taken to drinking and was physically assaulting Kate, to the extent that she had to live with Social Care. Michael, in spite of recent behaviour, continues to be fond of their children, visits them often, buys presents, but does not want to shoulder day-today responsibilities bringing them up. Kate, being pregnant and financially dependent on Michael, was finding the situation difficult. Michael moved out of the family home and Kate moved into Grimesbar from Social Care, as it was easy to find accommodation in Grimesbar. She now lives in a four storey tenement with common entrance that is not particularly secure, and the building is scheduled for demolition. That being the case, many of the flats are empty, and Kate lives in an insecure and isolated building. Kate, being a non-practising Roman Catholic, considers other Church going single mothers as ‘holy.’ She does not particularly keep in touch with social workers and in the meantime, becomes friendly with local community activist Frances Kane, who helps Kate in looking after children. She has two teenage children of her own, a daughter training for a career and the boy in armed forces. Her husband Bill, a Lorry driver, stays away from home a lot due to his work schedule. Frances likes to look after Jade and Scott, and Kate leaves them more and more in her care, because Kate has started working and finds it almost impossible

Media Meanings - Essay Example Racism played a major role in this movie, seen as a negative aspect in the children’s attitudes and mentalities. Racism is defined as unconstructive behaviour on an incorrect assumption that one race is intrinsically superior to others. This is one of the many forms of bigotry which is defined as unjust actions directed against people based on their gender, race, nationality, ethnicity, language, or sexual direction. Throughout the movie, there are many examples of racism. Basically, the students going to that high school come from different background, and therefore, at high school, they create separate â€Å"tribes†. Such tribes where â€Å"south of the boarder – Latinos†, â€Å"little Cambodia†, â€Å"the ghetto†, â€Å"Wonder bread Land†, and others that were not mentioned. All of these â€Å"tribes† believed that their race is superior to the â€Å"other†, and if that â€Å"other† particular race would not exi st, their life would be much better. From this, many problems leading to violence, and even crime, aroused. Many students went to boot camps or jail for youths, and lost a lot of their friends because of gang related activities. In addition to this, in the movie it was mentioned that in Long Beach, the place where the action takes place, it all comes down to what you look like; Latino, Asian, Black, etc. They are so buried in their hatred towards each other that it is likely to get shot anytime you walk out of your door. The students fight each other for territory; kill each other over race, pride and respect. Prejudice is seen in the movie as well. Prejudice is defined as a set of opinions, attitudes, and feelings that unfairly cast a group and its members in a negative light, without legitimate reasons. In a way, prejudice is tied to stereotype. On the other hand, stereotypes are more a false or generalized belief about a group of people that result in categorizing members without regard for individual reference.

Basic hazardous waste management (Blackman, 2001) Essay

Basic hazardous waste management (Blackman, 2001) - Essay Example The management helps in safe handling and proper disposal of the waste products. Spit cups are containers used to spit on. They are of different models and types and thus while being collected to be disposed they require specific selections (Blackman, 2001). Those involved in collecting the spit cuts should wear protective clothing’s since the materials are not safe to be collected with bare hands. Differentiate the different makes and materials used to make the spit cups. Check if the material is extremely hazardous from the list of the known and extremely hazardous materials. If not in the list proceed to the next step. If material found extremely hazardous, it should be disposed, as such waste and should not be rinsed. The liquid hazardous material in the next stage should be empty, and no liquid should drain from it. Spit cans fail to qualify as empty. Label the waste with hazardous waste tags and a request for collection to hazardous waste collection team follow (Blackman, 2001). The environment, health, and safety then collect the waste for disposal as hazardous waste. They will facilitate and dispose the material waste generated by UCSD

Case Study Essay Example | Topics and Well Written Essays - 1000 words - 1

Case Study - Essay Example The company reviewed it’s its operations in the 2006 when SABMiller had just completed a three-year turnaround plan, establishing a platform for future growth. From that report it can be noted that in North America the company had made progress as it had continued to grow while giving better prices to the customers than its competitors in that market. SABMiller had heavily invested in that market which enabled it succeeds in price cutting without passing on the costs. It had a three year investment strategy which has enabled to remain strong despite tough conditions. From the foregoing, it can be deduced that SABMiller’s strategy in the North American market is heavy investment which in turn enables it lower prices hence driving out competitors (Hal, 2002). In relation to Europe SAB’s strategy was to increase its share and to expand its capacity. This was to be achieved through introduction of new brands and new packaging methods. This strategy has enabled it to increase its share, volume and expand its capacity in various European markets. SAB’s strategy in most of the countries has been to acquire an initial local stronghold firm to enable it advance into other markets which it had not penetrated before. It has achieved this by acquiring other brewing businesses in most cases to focus on brand portfolio which gives it a better market position, increases sales and to enjoy economies of scale in production and distribution. It seems that SABMiller has shifted its focus to developing countries having already established a substantial presence in the developed countries. It realised that its ability to succeed in developing countries has proved to be of advantage. This was noted in the company’s report of 2006. This strategy has to an increase in consumption of soft drinks by consumers in South Africa which in turn has led to increased sales ( Donald , 2008). To meet the demands of changing consumption patterns, SAB has introduc ed new sales and distribution systems and enhanced the flexibility of its production facilities. It has licensed more agents has brought more outlets into the mainstream. This means they can now operate more professionally and it can deliver to them direct - which in turn raises the performance of the business. The stakeholders expect that SAB’s businesses in Africa will continue to grow being helped by broader distribution and a clearer segmentation of SAB’s brands. The stakeholders also see plenty of opportunity to keep improving efficiency in these relatively underdeveloped countries and see the outlook for Africa as a whole to be encouraging. Possible strategic options open to SAB First of all, SAB can penetrate the market with its current products. This can be through heavy advertising or using any other strategy enable existing and potential customers get knowledge of its existing products. With this option, SAB needs to come up with a strategy to enable it incre ase sales to its current customers by convincing them without change of its original products. SAB can also gain competitors customers by improving the quality of its beer compared to that of its competitors. Since it is cheaper to retain current customers than acquire new ones, hence in this option SAB needs to improve its relationship with its current custo

Psychological Effects one can have due to Sleep Deprivation Essay Example for Free

Psychological Effects one can have due to Sleep Deprivation Essay According to Kozier et Al. (2002), sleep is the state of being conscious wherein there is a decrease of perception, and reaction to the environment of an individual (p. 953). Sleep exerts physiologic effects on both the nervous systems and other body structures and also it restores normal levels of activity and balance among parts of the nervous systems (p. 956). There are two types of sleep, NREM sleep and REM sleep, NREM sleep or non-REM sleep is a deep, restful sleep and some physiologic functions were decreased. It is also referred to as a low wave sleep because when a person sleeps the brain waves tends to slow than the alpha and beta waves of an awake person. NREM sleep is divided into four stages: stage 1- very light sleep wherein the person feels drowsy and relaxed, stage 2- light sleep that will last only from ten to fifteen minutes, stage 3- domination of parasympathetic nervous systems that slows down the heart and respiratory rates as well as other body processes and sometimes snoring may occur and the fourth stage will be the deep sleep is thought to restore the body physically, dreams and rolling of the eyes may occur in this stage. Another type of sleep is the REM sleep or the rapid eye movement sleep that constitutes 25% of sleep of a young adult and usually recurs every ninety minutes and lasts five to thirty minutes. On the other hand, dreams in REM sleep were usually remembered because it is consolidated in the memory (pp. 953-954). There are many factors that may affect sleep of an individual, quality of sleep and quantity of sleep were both affected by a number of factors. The quality of sleep is the ability of an individual to stay asleep and to get the required amount of REM and NREM sleep while the quantity of sleep is the total time the individual sleeps. Age, environment fatigue, life style, psychological stresses are just some of the factors that indeed affects the sleep of an individual (p. 956). Literature Review In an internet article, they listed six persons that have a contribution in sleep research. A French Scientist Henri Pieron authored a book entitled â€Å"Le probleme physiologique du sommeil,† which was the first text to examine sleep from a physiological perspective. This work is usually regarded as the beginning of the modern approach to sleep research. Dr. Nathaniel Kleitman, now known as the â€Å"Father of American sleep research,† he started working in Chicago in the 1920’s questioning the regulation of sleep and wakefulness and of circadian rhythms. Kleitman’s crucial work included studies of sleep characteristics in different populations and the effect of sleep deprivation. Another contributor is questioning the regulation of sleep and wakefulness and of circadian rhythms. Kleitman’s crucial work included studies of sleep characteristics in different populations and the effect of sleep deprivation. Dr. William C. Dement extended Dr. Kleitman’s path of research. Dement described the â€Å"cyclical† nature of nocturnal sleep in 1955, and in 1957 and ’58 established the relationship between REM sleep and dreaming. In 1958, he published a paper explaining that in a sleeping cat there is a cyclic organization existence, thus creating an explosion of fundamental research that gathers researchers from different fields of specialty. For the next 20 years, Michel Jouvet leads to an identification of REM sleep as an independent state of alertness, which he called â€Å"paradoxical sleep. Another one is H. Gastaut and his colleagues discovered the presence of apnea during sleep in a subgroup of â€Å"Pickwickian† patients (1965) that lead them to an outbreak of investigations of the control exercised by the â€Å"sleeping brain† on the body’s vital functions. His work eventually led to the new discipline of â€Å"sleep medicine† (A brief history of sleep research, â€Å"n. a. †). Sleep deprivation and its causes According to Kozier et Al. (2002), sleep deprivation is only one out of many common sleep disorders. They defined sleep deprivation as a syndrome of prolonged disturbance that leads the amount, quality, and consistency of sleep to decrease and thus produces a variety of physiologic and behavioral symptoms, its harshness will depend on the degree of the deprivation. Again there are two types of sleep deprivation REM and NREM deprivation, the combination of the two deprivation increases the severity of symptoms. Alcohol, barbiturates, shift work, jet lag, extended ICU hospitalization, morphine, and meperidine hydrochloride are the causes of REM deprivation, while all of the causes of REM deprivation plus diazepam flurazepam hydrochloride, hypothyroidism, depression, respiratory distress disorders, sleep apnea, and age causes NREM deprivation, and both REM and NREM deprivation is caused from the combination of both REM and NREM deprivation causes (p. 959). Another cause of sleep deprivation is from the psychological stress wherein anxiety and depression frequently disturb sleep. A person can’t relax adequately to get to sleep if he or she is having a personal problem. Another factor is alcohol and stimulants, people who drinks alcohol excessively has the higher rates of sleep disturbances. Alcohol disrupts REM sleep even though it fastens the onset of sleep. Diet- weight loss is accompanied with reduced total sleep time as well as broken sleep and earlier awakening. Smoking, cigarettes contains nicotine that has stimulating effects on the body and may cause in difficulty of falling asleep. Motivation, person’s desire to stay awake can cause a fatigue, and illness, an ill person is more prone to sleep deprivation, in their condition they need to have more sleep, but a patient in a hospital is disturb by their time to take their medicines, and respiratory conditions can also disturb sleep thus disturbing their total time of sleep a person is required to have (p. 956). Psychological and physical effects of sleep deprivation  The effects of sleep deprivation to the body is like a chain reaction, its main target is the brain, since the brain is the control unit of the body, the brain controls and is responsible for the homeostasis of the body, once the brain is affected many imbalances may occur. For REM deprivation excitability, restlessness, irritability, increased sensitivity to pain, confusion and suspiciousness, and emotional liability can possibly be the effects. For NREM deprivation one may show hyporesponsiveness, withdrawal, apathy, feeling physically uncomfortable, lack of facial expression, and speech deterioration. For both REM and NREM deprivation, inattentiveness, decreased reasoning ability and the ability to concentrate, marked fatigue manifested by blurred vision, itchy eyes, nausea, headache, difficulty in performing activities of daily living, lack of memory, mental confusion, visual or auditory hallucinations and illusions can be its primary effects to one’s both psychological and physical aspect of a person. Since stress is one of the major factor affecting sleep deprivation whether it’s psychological or physical stress. As you think more and focuses your mind into the problem, your mind will become more fatigue (p. 959). Based on the book by Biron et Al. (2006), stress may lead to some psychological problems and may interfere with effective intrapersonal and the intrapersonal behavior of the individual. A person experiencing prolonged stressful events may suffer from feelings of helplessness and hopelessness, and consequently, undermining his self esteem. Impaired task performance is another effect of stressful mind; it interferes with our ability to successfully perform a task and responsibilities expected. And disruption of cognitive functioning, people who are under stress are likely to experience loss of concentration, disorientation, and forgetfulness (pp. 184-185). Treatment for sleep deprived persons According to the book made by Kushida (2005), pregnant women are also prone to sleep deprivation. In treating sleep deprivation for pregnant women, they recommended seven treatments to minimize maternal and fetal health risk: a) women should try to seep on the left side and avoid sleeping in supine position.  Avoiding it will ease the stress of the heart, will reduce constriction of the space available to the fetus, will reduce pressure to the inferior vena cava that carries blood back to the heart from the feet and legs, b) if symptoms of RLS are present, consider an evaluation of ferritin, hemoglobin, and folate levels and supplement when indicated, c) treat sleeping- disordered breathing with CPAP, d) avoid staying in bed when unable to seep, e) address anxiety provoking issues to reduce overall level of arousal, f) Consider regular exercise, pregnant women who exercise three times a week for at least thirty minutes have less insomnia and anxiety than pregnant women who do not exercise, and g) treat psychophysiological insomnia with empirically supported cognitive behavioral therapy for insomnia (p. 185). Another form of treatment is discussed by Greist and Jefferson (1992), psychosurgery is a rare treatment; it is not then advisable if other treatments have not been tested to a patient. Careful neurosurgical interruption of brain pathways has been shown that fifty percent of patients has been helped to this kind of treatment (pp. 79-80). Conclusion: Sleep is really a helpful in obtaining our health; it restores our body’s energy. Sleep deprivation is not really a syndrome but an effect due to some disturbances, stress, and anxiety that makes our brain to send signal to our body to be awake, an unnecessary awakening that affects our total time of sleep.  When our body is stressful or lack of average sleep needed by each individual, our brain do not work properly thus affecting our lifestyle, our ability to think and cope up with problems, and then other diseases may occur if not immediately taken to concern, because stress attacks our brain and knowing that our brain is the control center of our body. Recommendation: If sleeplessness and the listed signs and symptoms occur, it will be a clever decision if you consult a Doctor immediately prior to health concern. It is also a best way if symposiums will be conducted or seminars that discuss about Sleep deprivation to school and or universities so that students and educators will be aware to the effects of sleep deprivation that one can possibly have due to body exhaustion and abuse.
