Corrective measures for today and the future Essay Example for Free

Corrective measures for today and the future Essay There are many ways to stop war drivers and hackers and these methods may be as simple or complex depending upon the nature of the network. First, one should understand that war drivers and hackers can easily tap into a network because of the plug-and play nature of modern devices. Also some advanced security systems such as the Wired Equivalency Privacy (WEP) system used by 802. 11b wireless networks is plagued by some common errors in the system, including failure to engage it entirely by itself or engage WEP encryption key set at default. Thus, method such as WEP, IPSEC, and Wi-fi protected Access, DMZs, Firewalls and Virtual Private Networks can be established to deter war drivers and hackers (â€Å"War Driving†, 2004). WEP Wired Equivalent Privacy (WEP) is basically a security protocol, specified in the IEEE Wireless Fidelity (Wi-Fi) standard (which is 802. 11b) designed to provide the WLAN a security level that matches a wired network. Security for a WLAN can be tricky, as access to a WLAN is not hindered by most physical barriers. WEP works by encrypting data before transmitting it to the wireless network. This encryption can be done in conjunction with other protection methods such as password protection, end-to-end encryption and virtual private networks (VPNs) (â€Å"Wired Equivalent Privacy†, 2006). But WEP is not without it flaws, as proven by a research group from the University of California at Berkeley. The group was able to intercept and change data transmissions and gone as far as gaining access to restricted networks and data. On the other and, WECA (Wireless Ethernet Compatibility Alliance) claims that WEP is not the only security system method available for WLAN. WEP is popular because most consumers have put up much of their trust in WEP that other methods (â€Å"Wired Equivalent Privacy†, 2006). IPsec IPsec (Internet Protocol Security) is defined as the backbone for a set of security protocols for network communications. IPsec claims to be effective in establishing virtual private networks and remote user access in dial-up accounts and private networks. One obvious advantage of IPsec is that security arrangements can be taken cared of without changing computers or users. CISCO (a major promoter of IPSEC) provides support for IPSEC on their network routers (â€Å"IPsec†, 2005). IPsec has two options for security service. First is the Authentication Header (AH), which basically authenticates the identity of the data sender and the other one is Encapsulating Security Payload (ESP) which handles both sender authentication and data encryption. Both services packages specific information into packets in a header that follows the IP packet header. Separate key protocols can be selected for this such as the ISAKMP or Oakley protocol (â€Å"IPsec†, 2005). ISAKMP (Internet Security Association and Key Management Protocol) is a coded protocol based on the IKE key exchange protocol (ISAKMP, 2006). On the other hand, the Oakley protocol is a security system in which two authorized parties can exchange confidential material through the Internet (Oakley Protocol, 2006). Both protocols can be used on a secured connection and is defined by RFC (Request for Comments) 2408 and 2412 respectively. Wi-Fi Protected Access Wi-Fi Protected Access (WPA) is a new security protocol that was designed to replace WEP. It is technically an improved version of WEP. Though WPA has improved data protection features, WEP is still considered to be best for home use. However, WEP is not recommended for corporate use because it is prone to eavesdropping and hacking, because it is not able to handle the bulk of data that WPA is capable of handling. WPA uses Temporal Key Integrity Protocol (TKIP) which uses pre-packet mixing function, extended initialization vector, and a re-keying mechanism. WPA is also said to have stronger user identification because it is based on 802. 1 xs and has an Extensible Authentication Protocol (EAP). Also WPA relies on RADIUS (a central authentication server) to identify each user â€Å"Wi-Fi Protected Access†, 2005). WPA is actually under IEEE 802. 11i, and there are rumors that a second version called WPA2 is on the works. It is also predicted that by 2003, there will be software updates that will allow both the client and server to establish WPA in their system. â€Å"Hotspots† can then operate within a mix of WEP and WPA modes to support both home and corporate clients. In case of a home client, the identification system would be simpler than the one that will be issued for corporations (â€Å"Wi-Fi Protected Access†, 2005).

Marijuana and College Students Essay -- Marijuana Students Pot

Marijuana and College Students Marijuana may control the way people act, think, and even hurt their college academics. Marijuana is one of the most popular used drugs in America ranking about third after tobacco and alcohol. Marijuana is a substance that has become very much a part of American culture; many college students have either used it occasionally or regularly. With that in mind, I thought it would be interesting to find out about students at Indiana University of Pennsylvania (IUP) and their use of marijuana. In fact most students might not even know what they are smoking and what exactly makes them feel the way they do. Exactly what is marijuana? Marijuana is made of the dried leaves and flowers of the female cannabis sativa plant, and looks like oregano. There are many different marijuana preparations that are widely used to obtain effects. It can be either smoked or taken by mouth. Marijuana can be smoked in the form of a hand-rolled cigarette ("joint" or "reefer") it is also smoked in a variety of pipes. Hashish (hash) is a dried-caked resin from the flowers and leaves of the plant. It is sold in chunks and cubes, and its color range from light brown to black. Hashish is often blended with tobacco and smoked. It is more potent than marijuana because it contains a higher concentration of THC. THC is the main ingredient in all cannabis preparations. The more THC cannabis contains, the stronger it is. The effects of marijuana are similar to alcohol intoxication. Small amounts can make you relaxed and generally less inhibited yet some users say that it enhances the experiences of music, food and sex. After hearing all about how college students feel about marijuana I wanted to find out for myself, so... ...re lighting up next time. Maybe they will wonder just what harm they have done to their body already. Many people that smoke marijuana have the effects that are discussed in this paper. It can plainly be seen, their lack of motivation and kind of "spacey ness" that is commonly associated with marijuana smoking. I often wonder what these people would be like if they stopped their use and allowed themselves to rid their body of the drug and its by-products. Marijuana use is still very popular throughout the United States, and the fact that people are not educated enough about its effects is very detrimental. These people are hurting themselves, and they don't know (and many just don't care) what they are doing to their bodies. If marijuana use continues to grow too much, we may have a country of unmotivated people, with many more health problems. Where will we be then?

Dec Of Independence Essay English

However, the document does not just serve as a list of misrepresentations and evils done by the King, but it in fact helps to outline an abstract plan of how the people of the colonies should live after secession from the Crown. Jefferson is able to annunciate, within the document, the utter importance of the basic rights all men should have. The Declaration of Independence also helps guide the people away from governments with unchecked power. Jefferson's overarching theme within the document is self- government and he writes with a huge emphasis on State representation.Basic human rights are some of the most controversial topics that the world has ever seen. The Declaration of Independence is no exception. The principles of the document all deal with basic human rights. Jefferson states the King's inhumane decisions and actions against the rights, we the people, ought to have as human beings. Jefferson states that we all have, â€Å"certain unalienable Rights, that among these are Life, Liberty, and the pursuit of Happiness. Jefferson has incredibly strong feelings about people who try to take away our natural rights and he wants to deter the States from being tuck under a government that does not respect those very rights. Not only as people do we have the privilege to these rights, but we also have the duty to preserve them at any cost. Jefferson's statements within the document help to show his true agenda; to offer a reason to change their society so that the people can be free without misrepresentation. Thomas Jefferson proves the importance of rebelling against absolute monarchs within his writing of The Declaration of Independence.He writes of how the King used his power for evil instead of good. For instance, Jefferson states, † He has plundered our seas, ravaged our Coasts, burnt our towns, and destroyed the lives of our people. † The people Of the colonies must stand up to the British Empire at any cost to preserve their liberty and fre edom. He puts everything on the table and provides a direction to a system in which States can govern themselves and depend less on a centralized government. Jefferson demands that the people of the colonies are able to live in peace whilst completely represented in terms of taxation, military endeavors, etc.Although at times Jefferson's words seem to sound like he has a literal plan of how the colonies should be governed, in fact, it is a philosophy that does not have to be limited to just those who live in the colonies, but any person or people that feel they have been unfairly or unrightfully governed. His words offer a powerful message that any oppressor, whether a single person or a unified government, needs to be dealt with and should never be allowed to continue with wrath. The only way to entirely get rid of tyrannical or corrupt leaders, kings, etc. is to give the majority of the power to each individual state to self-govern.Jefferson feels above all else that state rights and representation are the most important ideals and values we, as a people, should have. The Declaration of Independence serves as a highly summarized game plan to create a less intrusive and less intensive government that will not unfairly govern the people. The document Serves as a message that the United Colonies are independent and shall govern themselves whether or not the King of Britain agrees. Jefferson demands that States at least have proper representation within a national government if there is to be one.Though, this document is not merely just a plan for a new government, it also serves as something more: an idea that will fuel freedom and a new beginning for the people. Jefferson uses several different means of getting his point across within The Declaration of Independence. He uses harsh examples of evil actions committed by the tyrannical government of Britain. Another example of Jefferson getting his point across is a brand new future he speaks of as well as hat th e States/Colonies could have if they get rid of the British monarch.
