Security Basics Essay Example for Free

Security Basics Essay Hardware firewalls are integrated into the router that sits between a computer and the Internet. They typically use packet filtering, which means they scan packet headers to determine their source, origin, destination addresses and check with the existing user defined rules to make an allow/deny decision. . Speed: Hardware firewalls are tailored for faster response times, so it can handle more traffic loads. Security: A firewall with its own operating system is less prone for attacks. This in turn reduces the security risk and in addition, hardware firewalls have enhanced security controls. No Interference: Since the hardware firewall is an isolated network component, it can be managed better, and does not load or slowdown other applications. The firewall can be moved, shutdown, or reconfigured with minimal interference to the network. Fortinet firewall. Its the most prominent hardware firewall proposed by Gartner technology research group which is widely used for Internet security. The key features of Fortinet hardware firewall are: Intrusion Prevention System (IPS) The IPS monitors network activities for malicious or unwanted behavior and can react, in real-time, to block or prevent those activities. AntiVirus/AntiSpyware/AntiMalware The advanced Antivirus technology ensures real-time protection against a multitude of attacks at the network gateway. Support two types VPN (SSL, Ipsec or Site-to-site) with bi-directional content filtering. Inspects all major protocols like SMTP, POP3, IMAP, FTP, HTTP. Software firewalls are installed on individual servers. They intercept each connection request and then determine whether the request is valid or not. Software firewall process all requests by using the server resources. Apart from performance limitation, the software firewall has numerous advantages. While comparing with the hardware firewalls, software firewalls are easier to configure and setup. Through the software firewall, we can restrict some specific application from the Internet. This makes the software firewall more flexible. The software firewall give users complete control on their  Internet traffic through a nice user friendly interface that requires little or no knowledge. Linux, CSF (ConfigServer Firewall) provides proven security via the control panels like cPanel, DirectAdmin and Webmin. From there, its quite easy to modify configurate files and stop, start and restart the applications. This makes configuring and managing the software firewall very simple. For windows, its recommended to stick on with the default windows software firewall because the third party software firewall will make the server overloaded and this leads to poor server performance. Task 2: McAfee, Panda, Norton, AVG, and Kaspersky all provides trail versions for their products. Only Panda, and AGV offer free versions of their software. Trojans horse programs in computing is generally a non-self-replicating type of malware program containing malicious code that, when executed, carries out actions determined by the nature of the Trojan, typically causing loss or theft of data, and possible system harm. This is usually contracted ironically when trying to rid your pc of viruses through online sites which are fakes and in fact introduce you to one. Malicious email attachments are a way for a sender to transmit files to another user via email. In a similar way to junk mail coming in your door at home, email users regularly receive unsolicited emails from unknown senders. These emails can often contain links to malicious web sites or have attachments containing malicious software. Usually contracted from opening emails from known unknown sources. Drive-by- downloads A drive-by download refers to the unintentional download of a virus or malicious software (malware) onto your computer or mobile device. A drive-by download will usually take advantage of (or â€Å"exploit†) a browser, app, or operating system that is out of date and has a security flaw. You get this by visiting websites running malicious codes. Task 3: Full Backups are- a complete backup of everything you want back up. Restoration is extremely fast because you’re only backing up one set. Drawback is the backing up process is slow, and requires high storage. Differential Backups look at which files you have changed since your last full backup and then creates copies of all the files different from that  one. Faster to create than full backups, restoration is faster than using incremental backup, and not as much storage is required as a full backups. Drawbacks are restoration is slower than a fullback, and creating differential backup is slower than creating an incremental backup. Incremental Backup- creates copies of all the files, or parts of files that have changed since the previous backups of any type. This method is the fastest when creating a backup, and requires the least storage space. Drawbacks it’s the slowest for restoration because it may require several sets of data to fully restore. Backups should be stored off-site because it’s a secured way of keeping files away from hackers, and potential virus, its always important to check to make sure it still functional. A cold backup site is little more than an appropriately configured space in a building. Everything required to restore service to your users must be procured and delivered to the site before the process of recovery can begin. As you can imagine, the delay going from a cold backup site to full operation can be substantial. There are the least expensive to maintain. A warm backup site is already stocked with hardware representing a reasonable facsimile of that found in your data center. To restore service, the last backups from your off-site storage facility must be delivered, and bare metal restoration completed, before the real work of recovery can begin. Hot backup sites have a virtual mirror image of your current data center, with all systems configured and waiting only for the last backups of your user data from your off-site storage facility. As you can imagine, a hot backup site can often be brought up to full production in no more than a few hours. Hot backup site are the most expensive approach to disaster recovery. Task 4: The password I choice to use was â€Å"Don’t worry about what life brings to you worry about how you’re going to deal with it!†Dwawlbtywahygtdwi24

In Response To Those Winter Sundays Essay -- essays research papers

In Response to "Those Winter Sundays" Being a child, is one of the hardest stages of ones life. They go through doing all the wrongs in order to do the right, and they socially develop into a mature and sensible human being. During this stage of a young child's life, the roles of parenting are absolutely crucial. In the poem "Those Winter Sundays" by Robert Hayden, I get a sense that the narrator does not have a special bond with his father, and that there is a sense of fear. I feel that in order to grow up and be a morally strong and stable person, you need a well-built relationship with at least one of you parents, if not both. Growing up in a very suburban town taught me many things about being a boy and even further into my life as a young man. I spent most of my childhood days running through the woods, fishing in our pond, or helping my father with some project that he had around the house. I used to always come back to him with everything for help. He would be doing something in the garage, and I would catch a fish that had swallowed the hook. I would run up to the house, break his concentration, and he would come help me. He always did that, and never seemed to mind it was like it was his job to love me and teach me how to be a good person. In the poem, I get a sense that there is no bond, like my father and I have which leads to confusion in the narrator's life. For instance, in line eight when he says "I would slowly rise and dress, feari...

Marijuana legalization

White House, it is the most commonly used recreational drug in the United States. It has been proven to be less harmful than alcohol, which is currently legal; and prohibition caused a black market to arise leading to an increase in an organized criminal activity. The fght against those organizations is costing a great amount of money and was cause for the loss of many innocent. While there are strong arguments in support of prohibition there are stronger arguments in support of the legalization if marijuana than there are counterarguments to keep the substance illegal.When comparing the Alcohol Prohibition in the 1920s and compare hat situation with the current situation with the legal status of marihuana, we cans ee that a repetition of history is occurring. According to Douglas McVoy, at the beginning of prohibition, the consumption of alcohol fell, however eventually it increased again. Since the drug was illegal and only the black market could sell it, a significant amount of ta x revenue was removed and crime rates increased in addition to become more organized.Consumption, illicit production, and distribution grow exponentially; therefore courthouses and prison systems were exhausted from such an increase in crime due to illicit alcohol. Government spent great amount of money devoted to enforcement, in fact, the annual budget of the Bureau of Prohibition went from $4. 4 million to $13. 4 million during the 1920s, while the Coast Guard spending on Prohibition averaged over $13 million per year. (McVoy). This are some reasons that proved that alcohol prohibition was a failure to the United States.Comparing the alcohol with the cannabis prohibitions. Marijuana is the most used recreational drug in the United States, as reported by the White House (Marijuana). One could say that after a long term of prohibition, the consumption rates have increased. Like in the 1920s with alcohol, there is now a huge black market that sells marijuana and its essentially lead by organized criminal groups. According to Steve Nelson, Marijuana offenses accounted for 48. 3 percent of all drug arrests in 2012 (Nelson) and more than 80 percent of marijuana arrests are now for simple possession (Kilmer,etc. . United States government spends enormous amounts of money in the fght against drugs and the criminal groups grow more and more each day. Alcohol prohibition was considered a failure and, actually, we are experiencing some situations today that the United States taced in the 920s Since betore marihuana was prohibited, the drug was used in a medical way. It has been proven that cannabis used as a medicine can relieve chronic pain, which is cause by a significant number of pain- producing illnesses.Marijuana can assist many mental health problems, such as attention deficit disorder (ADD), post-traumatic stress disorder, obsessive-compulsive disorder, and depressions. It can also be used as an analgesic (painkiller) or an anti- inflammatory drug for autoimmun e diseases, diseases that arise when the body cannot create an appropriate immune response to substances or tissues present ormally on the body. Such diseases could be rheumatoid arthritis, complex sympathetic dystrophy, and so on (Bearman). California was the first state in the United States that legalized medical marijuana.One of the negative results of this legalization is the significant increase of individuals seeking treatment for marijuana abuse or dependence (Kilmer, etc. ). This could mean that there has been an increase in consumption. One interpretation of this phenomenon is that people which use marijuana as a recreational drug rather than a medical drug, seek treatment not to eal with a substance abuse but to manage a legal problem (Kilmer,etc. ). Even though marijuana can be used as a medical supplement, this does not mean it do not have secondary effects on human ‘s bodies.Marijuana can also get to be harmful. In fact, THC (The major component in cannabis that g ets you â€Å"high†) by binding to receptors in the basal ganglia and cerebellum can disrupt coordination and balance of the body. Therefore doing complicated tasks such as driving, participation in sports, or learning is affected. One of the long lasting effects cannabis can produce on you is psychotic disorder such as schizophrenia. This illness alters a person's ability to make good Judgments, understand reality, communicate or think clearly.Memory can also be affected by marijuana consumers, studies has proven that THC alters how information is processed in the hippocampus, a brain area responsible for memory information (National drug Institute). According to the National Institute on Drug Abuse, marijuana also affects your cardiovascular system. After a few minutes of inhaling marijuana smoke, the heart rate, which is normally between 70 to 80 beats per minute, may increase by 20 to 50 beats or even double in some cases. Mixing marihuana with other drugs can amplify thi s effect.This means that a person's risk of heart attack during the first hour after smoking is about four times his usual risk. (National Institute on Drug Abuse) Before legalizing and decriminalizing the use and possession of marijuana, a regulation system should be instituted, that, like Douglas Mcvay stated, should not be the same as systems used during the legalization of tobacco and alcohol. Those models of legalization taught the world and the United States a lesson of how not to regulate the use of these drugs (McVay).Cigarettes and alcohol advertising companies spend significant amounts of money to promote the use of their products which ultimately contributes to many health problems and eventually the death for many users. An example of a non-regulated drug after it was legalized was after the repeal of alcohol prohibition, where the death rate from liver cirrhosis increased dramatically (McVay). To prevent the abuse of marijuana, governments should build a system to regul ate its use. An important part of the system build for legalization according to RAND Corporation is the price the drug is going to have.
