Because CC came from TCSEC, they have some similarities but actually they are quite different. TCSEC only applies to operation system and it focuses on the demand of confidentiality. CC has full description of security mode, security concepts and security functionality. Level C: Discretionary protection Level C provides audit trial protection and Level C includes C1 and C2.C1 is discretionary security protection and its class is lower in Level C. C1 provides discretionary access control and it has the responsibility for Identification and authentication. C2 has all the security features of C1 and has the function of audit trail and access protection. C2 requires single- user log-in with password and an audit trail system. C2 works through log-in process, security event and source isolation to increase access. EAL7- Formally verified design and tested. It is applicable to safe TOE development and it applies to places where the risk is very high, or high value assets that worth higher expenses. Trusted Computer System Evaluation Criteria (TCSEC) was the first computer security evaluation standard which was published by the U.S. defense department in1985. TCSEC influenced other European countries and very soon some countries based on TCSEC to develop their own security evaluation standards. Form the above comparison of the differences between TCSEC and CC, we can point out that CC is a relatively successful security evaluation standard because CC has some advantages. CC is an international security standard and many countries acknowledge the testing result. Figure 1 - The PP/ST specification framework [7] Common Criteria provides a set of Evaluation Assurance Levels (EAL) from EAL1 (lowest) to EAL7 (highest) and it will be awarded to products and system upon successful completion of evaluation (see Table 1). The Common Criteria is absorbed by ISO (NO. 15408) Describe the similarities and differences between the two standards and state the advantages of CC. Some journals, articles and books are used in this report which can be found in the references. Background- explanation of TCSEC and CC. In this essay TCSEC and CC will be discussed, compared and contrasted to find out the similarities and differences and the strength of CC will be indicated. TSCEC is only used in U.S. In the beginning, it was proposed that TCSEC was to focus on independent computer system and it suited evaluation of military operating system. TCSEC does not involve security criteria for open system and it is the criteria for static model. TSCEC just considered protecting system - owner and operator but did not cover user security area especially for the security of telecommunication system user. And also only considered confidentiality for documents of system owner and it did not address integrity and availability. From Table 1 we see that the evaluation of TCSEC is mix security and functionality. So if any hardware of software is changed, it will start to evaluate the system again. EAL2- Structurally tested. In the delivery of the design information and test results all types of writing essays, EAL2 requires the developer collaboration. But do not spend too much energy beyond the good commercial operation of consistency. Introduction- brief description of the topic. The outline of the report is as follows: Even though TCSEC has been replaced by CC, they still have some similarities. Both of them are security evaluation standard and evaluate computer system by security level classification and each level has security requirements. Both of them provide confidentiality security functionality and evaluate Computer Operation System. CC provides a set of security criteria in detail and the criteria details are easily understood by customer and supplier. Customer can use them to determine the security level of the products and also to find out their own security requirements. So that supplier can design product for them and also use them to identify their product or system security features. EAL5- Semi-formally designed and tested. It enables the developers to obtain maximum security from the security engineering. The security engineering is based on a strictly commercial development practice. It relies on the appropriate application of professional safety engineering technology for support. Protection Profile copy TCSEC security requirements of C2 and B1. Protection Profile include: a template of commercial security profile, Firewall profiles which use for packet filters and application gateways, Smart card profiles, Database profile and a role which is based on control profile [16]. You knew we would get kicked out of there if you offered me that apple I accused. From the window of the Cessna, Again she looked confused. Then her face cleared. Oh! I understand! She closed her eyes. If I cant see the pebble, then the pebble doesnt exist! The last time I believed in reality I found myself counting how many forty-five degree angles there were in a square. I am something of a creature of two worlds, or at least of two great interests. I used to wonder which would be the greater mastery and how I could better serve the world: as a scientist or a musician? I have slowly come to realize that the best answer to that question is simply that the question is irrelevant. I'm sure you all have a lot more intellectual/creative/better essays than I do. I didn't get my acceptance/rejection letter yet, so I'm still holding out hope that this essay was good enough to get me in. What do you think? There must be an answer. I thought to myself. I example of personal essay writing, a thinking being, must be able to deduce the answer to any question I can pose. I could not. Every argument I concocted I just as easily repudiated. I only got back to where I began- nowhere. I have really enjoyed the essays you have posted I suddenly felt very dizzy and sat down. I picked up a pebble from the ground and looked at it I needed something for my mind to stick to, because suddenly it felt more than a little loose. My 18 years have been fortunate onesI grew up in a relatively affluent area of the city, surrounded by the constant love and affection of my parents, grandparents, aunts and uncles. I attended private school, went to summer camps and on nice vacations. Ive had a very sheltered existencebut that is not to say that I want my life to stay that way. At this point I must have looked upset because she put her hand on my shoulder and kissed me on the cheek. What you see is what you get! she repeated to herself in a singsong voice. Now, some might view my experience at a private Jewish high school to be narrow compared to the cultural diversity found in a public school. I might have thought so too, early on, but I discovered the rich Jewish culture that underlies and inevitably influences my life. After readingin the original Yiddishthe stories of Morris Rosenfeld, I came to appreciate the cultural meaning and rich history behind the language my grandparents spoke (when they wished not to be understood). I really enjoyed writing this one; it's actually the second Chi essay, the one about literary works and what not. No, youve got it I neednt concern myself with hypotheses that cannot be falsified. I am a man of science. His dismissive reply left me in the same place I started. No its not just sight! I said, exasperated. Its all of your senses! If you can see the pebble you know its there, if you can feel it you know its there, if you can hear it falling to the ground you know its there, if you can smell it you know its there, if you can taste it you know its there! Ignoring it doesnt make it go away. I nearly choked on the apple. But, but I sputtered. As I was escorted to the door of the building I noticed Eve had followed. It was when I was standing outside wondering how I had gotten there, that she walked in front of me, smiling that infernal smile. Essay Option 1 As I walked out of his office I overheard a toddler importuning his mother. But why? he asked time and time again. His mothers repeated explanations failed to satiate his need for knowledge. He continued probing. Her explanations eventually focused on the existence of the universe. The toddler was not pleased. Why does the universe exist? Actually, I do. I said. I was really annoyed now, and I didnt feel like playing her game anymore. The mind that does not stick She furrowed her brow. Yes I think I understand now. No! You I you didnt I was really pulling at my hair now. The pain kept me convinced I was real. Look what you did, I said. You got us kicked out. It was nice buffet they had in there free too. That is what empirical evidence indicates. He retorted constantly. I pretended to examine her closer. My word! How could I have forgotten you my queen! Its all of this haziness about time I cant decide whether Im going backward or forward so sometimes faces get a little jumbled up. I meet so many former wives nowadays its a little hard to keep track of them all. What did you say you name was again? I was playing along, trying to decide whether I should order her a white jacket or a cup of coffee. Oh, but you havent heard the best part she said my family essay conclusion, her eyes twinkling. If Im dead, she responded, then I dont exist, therefore I dont know that there is a world to believe in. Therefore for me reality doesnt exist. I was lost. In every other field I had studied reason provided a clear path to knowledge. This time, however, reason led me nowhere. Every time I thought I had deduced the logical path to a new idea I discovered faults in my logic that left me in the same place I had started. I could not find any axioms of knowledge. A very interesting story. If youll excuse me I said, trying to make a quick exit. booptroop Registered User Posts: 178 Junior Member Just like that good little monkey, Ive always had more than a healthy curiousity for knowing more. Over time, Ive delved into various subjectsfrom attempting to read and understand Ulysses to learning about the stock market, to teaching myself guitar and bass. At times, I was consumed by the sheer obsession of wanting to know everything possible about the subject at hand. But its not enough to merely be able to quote lines or know what a stochastic oscillator is. I then sought out a venerated scientist. I asked him my fabled question essay writing argumentative examples, expecting a meek response. Instead, he began a dissertation on the mechanisms of the universe. But why is it that way? I asked again and again only to be met with another wave of explanations. In another universe you were my husband. She was all teeth now, her face broken out in a huge smile. I smiled too. If this was a pass at me essay on proofreading, it was certainly the most unusual Id ever heard. Well that and I dont get too many passes. Myself Registered User Posts: 367 Member Reading everyone else's essay, I feel entirely sub-par. Be honest if you have any put-downs or whatever. I think I'm a very bad writer and I'm really surprised that I got in at all. Now that I think about it my essay just sort of ends in the last paragraph. My last sentence is super corny but I decide to keep it in because it's true and it was the best way to express how I felt. Anyways, no one's perfect (but some, like me, are less perfect than others). I applied EA: God is the uncreated creator. The memorized rebuttal carried with it contempt towards my lack of knowledge of theological canon. I left the conversation refusing to accept any axioms of my existence.
