Firewalls and DMZ - Assignment Example Benefits and Limitations of Firewalls There are several advantages of implementing firewalls at the personal level. A firewall based personal security system comprises hardware and/or software that stop an illegal attempts to use data, information, and storage media on a network (Shelly, Cashman, & Vermaat, 2005, p. 574). In addition, a personal firewall is a utility program that perceives and secures a personal computer and its information from illegal access. Personal firewalls continuously check all the inside and outside communications to the computer and notify of any effort of illegal access. Also, Microsoft's operating systems, for instance, Windows XP, incorporate a personal firewall (Shelly, Cashman, Vermaat, Cashman, & Vermaat, 2004, p. 574). Obviously, a firewall itself must be protected and attack proof, if not its capacity to protect links can be diminished. The implementation of firewalls provides several advantages to the organizations. In an organization, a firewall i s a computer or router that is located between the trusted and un-trusted computers (Silberschatz, Galvin, & Gagne, 2004, p. 692). It confines the network use between the two security domains, and checks and logs all links. Also, it can confine links based on starting place and target location, source or targeted port, or way of the link. For example, web servers utilize ‘http’ to carry out communication with web browsers. A firewall as a result may permit only http get ahead of, from all hosts external to the firewall simply to the web server inside the firewall (Silberschatz, Gagne, & Galvin, 2004, p. 672). Although, the use of firewalls provides help against security threats, but it is not helpful in all the situations. For instance, a firewall is not useful for the threats that are channeling based or go inside protocols or links that the firewall permits (Ioannidis, Keromytis, Bellovin, & Smith, 2000). Additionally, in case of the firewall installation on a persona l computer the speed of processing goes really down that makes the overall processing more problematic and performance slows down because the content of the data and information traffic is checked and confirmed by the firewall. Also, the longer response time in case of web based working and data retrieval. Sometime firewalls are not able to protect computer from internal sabotage inside a network or from permitting other users to right of entry to your PC. Moreover ,Firewalls sometimes present weak protection against viruses' consequently, antiviral software as well as an intrusion detection system or IDS that defends beside port scans and Trojans should as well complement our firewall in the layering protection (Wack, Cutler, & Pole, 2002; Thames, Abler, & Keeling, 2008). The utilization of firewalls in the organizations is not useful in all the situations. For instance, in an organization's business data buffer-overflow threat or attack to a web server cannot be dealt by the firew all for the reason that the http link is permitted; it is basically the contents of the http link that address the attack (Silberschatz, Galvin, & Gagne, 2004, p. 673). Also, denial of service attacks in an organizational structure are

Summarizing how information security - Essay Example Information Security System of Citibank With Respect To CIA Triangle CIA Principle The CIA triad namely Confidentiality, Integrity and Availability can be considered as one of the simple and widely applicable security models for an organization which assures to protect all kinds of information from external threats. These three major principles are supposed to be relevant with the entire security analysis of an organization (Imperial College London, 2012). Confidentiality: Confidentiality can be acknowledged as the ability to maintain secrecy of information from unauthorized external users. It is possibly the major apparent aspect of the CIA triangle in terms of security assurance for an organization. However, this principle is frequently attacked by the external users through Cryptography and Encryption techniques in order to transfer files or information from one system to another (Imperial College London, 2012).

It has been learnt that Citibank manages the personal data, records as well as information of each client in an appropriate manner and with the assistance of Citi Records Management Policy as well as Citi Data Management Policy. Furthermore, the organization implements advanced security processing system of each data, record or information that are collected from individual clients in terms of appropriate and secured storage capacity (Citigroup Inc., 2012). Availability: This principle of the CIA triad relates to the accessibility of transaction records or information by an appropriate and authorized user at the right time. However, various security issues with respect to accessing transactional record and information of a client by other external or unauthorized persons have been recorded. The organization is known to adopt an advanced form of process to identify the appropriate and authorized persons (Citigroup Inc., 2012).

Subsidies are also one form of social services as the Government Essay Example for Free

Subsidies are also one form of social services as the Government Essay With the increasing diversity and complexity in which services are facilitated by the United States Social Welfare system, it needs to be elaborated and reviewed accordingly so as to help benefactors get the best of what they have and necessitate the optimum available alternatives on their part. One important example given in the text is the power over decisions. This initiative enables and evokes the â€Å"right to make decisions that serve self-interests of a particular group with which decision maker is affiliated† (Chambers and Wedel, 2005, p.   94). This example can best serve if for example the healthcare department of one state agrees to place a qualified professional to make decisions on what programs need to be tackled for a particular period. On the other hand, this initiative can be costly to individuals and groups if the decision making process is tainted with a subjective purpose. For instance, a designated man may advocate a particular scheme because his company or service can benefit more in the process while disregarding the needs of other groups. Subsidies are also one form of social services as the Government tries to shoulder various expenses incurred in some aspects mandated by law (Chambers and Wedel, 2005). In here, the positive aspect of such facet can be the government reaching out to starting sectors in the economy and giving them the needed boost to succeed. On the other hand, one negative aspect of this is that not all sectors are given subsidies. Due to this, only selected and limited parties benefit from the process. Lastly, positive discrimination is a form of social service that tries to provide individuals and groups who have been treated harshly or unequally by the government (Chambers and Wedel, 2005). It is a form of setting restorative justice for those individuals discriminated by the old system. This connotes a positive attitude because it the Government tries to reach out and provide the necessary changes in their lives. For example, an African American was not given a good job despite his credentials has the option to apply for this. Contrary to these, it also brings about the question of its legality and notion of the action to create restorative justice. Due to this, limited people receive this kind of service and are primarily determined by court. Reference Chambers, D. E. and Wedel, K. R.

The Love Jesus Christ Gave To Me

The Love Jesus Christ Gave To Me Without a doubt, with the love and spirit of Jesus Christ directing my life, I have experienced and a deeper relationship with Him and I have grown in my ability to trust Him. The love Jesus Christ gave to me is like the currency of Gods kingdom. And it is because of his selfless love that I think of my faith in Him as the act of holding out my hand in the darkness and allowing Him to hold me as I walk through life. I gave my life to Jesus at an early age of seven years old and rededicated my life in my late teens. And, it has not been an easy road, but every time I felt unworthy of His love, I remembered the way Christ suffered for our sins. There are still days that no matter how hard I work, I feel unappreciated and unproductive. At times, I will hide my tears and use my laughter to hide my pain. But, whenever I close my eyes in a moment of prayer, all I can see are my disappointments, my past sins, my actions and the carelessness of my words. But, above all, I remember His love, a love that has unselfishly nourished my soul, given me the light to dust off, spread my wings and fly, and a love that has made me to cry out for Him without fear, knowing that He will respond, and give me my hearts desires. Indeed, the love of Jesus Christ has changed my life and I believe that in order for anyone to personally experience it like I have one will never truly understand. It is a love, that is so unselfish, pure, and every day as I reflect back on my personal relationship with Jesus, it is like am falling in love with Him more and more each day. Discussion I gave my life to Jesus Christ at an early age of seven and rededicated my life in my late teens. All my life, until I rededicated my life to Jesus, I always thought that I was supposed to live my life doing my own thing just following some rules and acknowledging that there is a God. I never really felt full, to be exact, spiritually content. I always thought something was not right, but I was not sure but today, I view acts of love as two pronged; one is an invitation from Jesus to seek out His love and two, it is an invitation from Jesus to seek Him out. The love Jesus Christ gave to me has made my faith in Him stronger. Numerous times, I reflect on faith. I strongly think that His love is the currency of His Kingdom. Whenever I think of His love as the act of allowing God to hold me as I walk through lifes challenges, I think of darkness. He is the father of lights, for darkness is as light to Him. Allowing Jesus to hold your hand is allowing love and light into your world. My thoughts on how His love feels like morph every time depending on the situation. I constantly think of it as an adventure. It is because of the love that He gave to me that my faith has many manifestations. Whenever I have a moment of reflection or I am with my friends, I have come to the realization that people, step out and walk on thin ice. For some people, it is like stepping out of their comfort zones, and for others, it is inviting the love of Jesus Christ into your life, and for some, it is simply holding out your hand in the darkness fully knowing that He will hold it because His love is immeasurable. And for some, it is touching the hem of His shirt for His goodness to flow into their lives. I think that at times, faith and His love do not make sense. And as I write this paper, I am tempted to think that if I question His love, then I am setting myself for frustration, and even failure. I have experienced conflicts with my faith. I believe this when I act contrary to His word and expect supernatural results. This is certainly when I at times try to author my own faith expecting Him to finish it. How often do we all author things in our lives then invite Jesus to complete them? My personal example is when I rededicated my life to God in my late teens; I got new friends and made myself believe that Jesus had authored it. Jesus was somewhat clear with me that it was not His will for me, but as sometimes we all do, I continued to insist on doing things my way, suffice to say, that my relationship with my new friends miserably flopped, probably because we were not reading from the same page. In my opinion, it is much worse dealing with a broken heart within the context of His love and faith. Here I was, sort of like a baby Christian, dealing with a broken heart, but I certainly learnt my lesson. Jesus loves me so much that He only finishes that which He starts or authors. It is because of His love that He will finish what He has started however we look at it. After rededicating my life to Him, I also noticed because of His love for me, I had been given a deep love for everybody. In simple words, I found it easier to love everyone; this is not an emotional love, or that lovey dovey kind of love, but it is a love that gives me a deep concern for the physical, mental and spiritual well being of other people. And it is because of this love that I am willing to sacrifice my prayers, money, effort, time, and so forth, for the benefit of other people. It is because of the love that Jesus gave me that I have enough love to risk being ostracized and misunderstood when I share the truth of His word. Whats more, since Jesus entered my life, I can no longer pass a beggar on the road. I normally feel compelled to stop and help out in any way I can. I have volunteered at shelters because the people sometimes need someone to talk to. Undoubtedly, my love is not perfect, but because of the love He gave to me, I would give everything that I have to help s omeone in need of help. Well, I am not there yet, but I have observed a dramatic and sudden difference in my behavior and attitude towards other people. In simple words, because of His love, my love for other people continues to grow. Furthermore, the first thing that I noticed following my rededication to Him is that I started to have an inexplicable desire to read His word. Earlier, when I tried to read the Holy Bible, it was a challenging task probably because it did not make much sense to me as it does now. However, from reading the Bible and listening to sermons in my local church, I realized that for the joy and love set before Him, Jesus endured the cross for all of us. We, as children of the most High, are so precious to Him. We are all a blessed product that simply cannot fail, because of His love. He trusted the earth to bring forth plantation and vegetation. He also trusted the waters ability to produce all types of water animals and fish. This is simply too amazing. It is because of His love that I am able to bank on the inherent and potential ability of His plans to manifest that which He speaks over. Words have immense power, they are spirit. He creates by speaking. Say what I want to see and see wha t I say. I am on this spiritual journey and I continue to remain open to learning more. Conclusion In sum, it is very clear that God houses ultimate faith and love. For whatever reason, He needs us to only have a little faith just little enough to be able to seek His love and forgiveness. And once we do, His love will give us all the proof that we will ever need to fully understand the love He gave us. That is what happened to me, and I got the greatest gift and surprise in my life, His love.

Hindu Gods in the Rig Veda :: essays research papers

The Hindu Tradition 1.) Agni Agni is mentioned as many different things such as: the household priest king god of sacrifice, most brilliant leader of all gods, wish granter, shines up in darkness, guardian of the order, lord of power and master of sacrificed food, always included in sacrifices to other gods, favorite priest, sharp sight of a poet, great speaker who inspires all with his shining speech, the first god to rejoice in human friendship, lord of tribes, the chief priest who finds riches and a combination of Indra (the strongest of all except Agni) and the wide striding Vishna who is worthy of reverence. Worshippers of Agni want to: hold a safe household, find riches and treasure, grow as a person in wealth and happiness, give animal (human?) sacrifice to him, be inspired by his speeches, protection of their tribes and always be granted what they wish for. Angiras Angiras was mentioned just once in this text as the mediator between heaven and Earth. This name is related to the English word: Angel. Varuna Varuna was said to have spread out the Earth, extended the air above the trees, put strength in horses, milk in cows, will power in the heart, fire in waters, the sun in heaven, Soma upon the mountains, caused rain by pouring his leather bag, moistened the Earth, to be the magic (maya) worker and measured the Earth to the Sun with a measuring rod. Worshippers of Varuna ask for reconciliation from him and forgiveness of sins or offenses. Mitra and Aryaman These two were listed but there were not any writings about them except that they did have powers. I wonder whether Aryaman is the Leader of the gods for the Aryan people or tribe. Manu The first man on Earth according to the Rig Veda, he is the Clan founder or Adam, Noah, Abraham or Moses. He is only listed on these texts. Indra Indra is mentioned in these texts as: the bull, the strongest of all that exist (except Agni), he is one of the most honored besides Agni, the warrior king of 33 gods of Manu, wielder of thunderbolt, a killer of dragons, killer of the first born dragon, overpowering the wily tricksters, the god who brought forth the sun, heaven and dawn, not having anymore enemies after Vritra, the greatest enemy of Indra, who challenged Indra, who is without shoulders. Indra killed Vritra with a thunderbolt, broke his nose and crushed him.

The History of Computers :: Technology Technological Computers Essays

The History of Computers Most of usà ¤participate in this digital culture, whether by using an ATM card, composing and printing an office newsletter, calling a mail-order house on toll-free numberà ¤or shopping at a mega-mall where the inventory is replenished just in time. (Ceruzzi 1) In the Information Age of today society has become dependent on technology; every aspect of our lives have become centered on how fast and efficiently something can be accomplished. The use of computers aids our stride to becoming technologically advanced. But how did we as a society arrive at such a point? How did we end up becoming so reliant on computers? These questions will hopefully be answered by looking back at the history of computers to date. During the WWII, Eckert and Mauchly designed and built the ENIAC, an electronic calculator that computed firing tables for the U.S Army; it established the era of computing in the United States. After the War, the drum came about as the reliable, inexpensive but slow memory device. ERA sold the drum machines, advertising their dependability, large storage capacity and their high speed capabilities. Eckert and Mauchly in 1951 started the intrigue with computers with their UNIVAC, a computer with computing abilities; as time passed the UNIVAC became essentially important. During the 1960Ï€s, The Case 1107 provided the main computing facility for Case Institute of Technology in Cleveland Ohio in the United States (Walker). The UNIVAC was extremely large yet quiet; its front cabinets ranged from floor to ceiling. The central processor was capable of computing simple arithmetic equations. The Case 1107 was one of the first computers on Earth to provide access from remote locations both at other locations on the campus and as far afield as Erie, Pennsylvania (Walker). A transformation in circuit technology during the 60Ï€s, enabled the transitor to become reliable and cheap enough to serve as the basic circuit element for processors (Ceruzzi 49). By 1971, Intel had already released the world's first generally available DRAM chip and therefore, built the world's first single chip general purpose microprocessor. Two years later in 1973, IBM developed what is considered to be the first true sealed hard disk drive.
