ITU-T Recommendation X.805 defines a security architecture for different networks where end-to-end network security is a major concern. This architecture is mainly applicable to wireless, optical and wire-line voice and converged networks.X.805 is also applicable to a wide variety of networks like service provider networks, enterprise networks, government networks etc. This architecture can be applied to network elements, security and applications in order to identify and correct security vulnerability.
The security architecture addresses three main issues regarding end-to-end security which are
1. What kind of protection is needed and against what threats?
2. What are the distinct types of network equipment and facility groupings that need to

Access Control-This security dimension limits the control and access to the network applications and services. It ensures that only authorized personnel can access the network elements or the stored information .Examples: Password
2. Authentication-Authentication ensures that the identity of a particular entity is true or authorized. It assures that no masquerade attack takes place by any entity. Data origin authentication and peer entity authentication are the two types of authentication. Example: Digital signature
3. Non Repudiation- This security dimension provides with the proof that the receiver has received the data from the alleged sender or the sender has sent the data to the alleged receiver without either of them denying it.
4. Data Confidentiality-This security dimension protects the data from unauthorized access. Example: Encryption of data.
5. Communication security-This security dimension ensures that data flows between authorized end points. It handles measures to control the traffic flows for prevention of traffic diversion.
6. Data Integrity-Data integrity ensures that the data is protected against unauthorized modification, deletion and provides a signal of the unauthorized
On this internet, the website said that there are two Calories per one mini marshmallow. The website also said that in one cup of marshmallows there is 159 Calories. This is the same as the back of the marshmallow label we had in class. On the label it said there were 83.2 Calories per gram.
Ensure that all necessary earth connectors are then attached to the isolation points and any overhead wires
When using routers, you need many routers in order to route the information to the correct location, as one router will not be able to manage this task. Explain how the routing schemes handle this problem.
Japan is an island nation off the coast of East Asia. It is made up of four large islands and about 3,900 smaller ones. On a map, they form a thin crescent moon. All together, they form an area about the size of Montana. To the west, the sea of Japan separates it from its nearest neighbors, Korea and China. To the east lies the Pacific ocean. Japan has a moderate climate. Summers are nice. Winters are mild, with heavy snowfall limited to the north. Japan makes crops due to rain in the summer.
2010 was the year for Jets fans they made it out of the regular season and into the playoffs, all the way into the Conference Finals. But no surprise, the Jets came up short again, losing to the Pittsburgh Steelers 24-19. After that, it all went down hill. The rankings of the Jets defense and offense decrease and with that so does their record, 8-8, 6-10, 8-8, 4-12, 10-6(glimps of hope), 5-11. With the decrease of wins most people, me included, you lose hope, and wonder when is that next year going to happen. If you want the easy answer as to why there is such a big difference between the years, just look at the Jets overall rating. It is like a roller coaster, from good one year to bad the next. But the real question is why was there this
1: The freedoms guaranteed by the fourth amendment are the most vulnerable to ethics violations in responses to terrorism. In fact they have already been threatened with the Patriot Act(Beau), NSA wiretapping(Sage), and the Freedom Act(Destiny). All of these acts have seen the United States Government be able to search through someone’s history without a warrant. The 4th Amendment States, “The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated”, and that “no Warrants shall issue, but upon probable cause”. This clear violation of the fourth amendment put Americans rights at risk. It may have seemed right at the time, but looking back we cannot watch everyone just to catch a few people who are doing the wrong thing.
I would include technology and software in a play-center for early childhood education because there are some educational games that can help you children learn. The games or things they do at school they can also do at home if they have the same program at home and they can show their parents what they learned at school. It can help children be better problem solvers and help teach them how to make hard decisions. Technology can help children learn more about the world around them and how the world around them works. They can be also taught how to use a computer which can be helpful in the future when they have to write an essay, fill out college applications or even job applications. We want our children to be prepared to help them in the

capacity and performance. However, as networks enable more and more applications and are available to more and more users, they become ever more vulnerable to a wider range of security threats. To combat those threats and ensure that e-business transactions are not compromised, security technology must play a major role in today's networks.
“ There is no measurement for acceptable security level, because the level depends on type of the information. An acceptable security level is always a compromise between usability and strength of security method”.(IJARCET, March 2013).
...vantage of the overall network design and implement usable subnets with virtual local area networks. Use encryption and encapsulation to secure communications of public segments to enable extranets and cross-Internet company traffic. Use items such as intrusion detection systems and firewalls to keep unauthorized users out and monitor activity. Taken together, these pieces can make a secure network that is efficient, manageable, and effective.
Authentication: The process of proving one's identity. (The primary forms of host-to-host authentication on the Internet today are name-based or address-based, both of which are notoriously weak.)
Implement physical security: - “Physical security protects people, data, equipment, systems, facilities and company assets” (Harris,
Privacy exist wherever personal information or other sensitive information is collected, stored, used, and finally destroyed or deleted – in digital form or otherwise. The challenge of data privacy is to use data while safe-guarding individual's privacy preferences and their personally identifiable information. The fields of computer security, data security, and information security design and utilize software, hardware, and human resources to address this issue.
