3.1 Network security Challenges
1. SQL injections: Hackers inject a malicious code in order to gain unauthorized access to databases to manipulate the contents, retrieve confidential data or even take control of the web server.
2. Cross-site scripting: Hackers inject malicious scripts, such as JavaScript, VBScript and ActiveX into a web page to execute the scripts on victim’s web browser. The attack could be used for illegal activities to access the victim’s information.
3. Man in the Middle attacks: In this attack, an entity tries to intrude in an ongoing conversation between a cloud server and a client to insert false information and to access information about important data being transferred between them.
4. Sniffer Attacks: These

Data Integrity: Sensitive data stored in cloud computing environment emerges as a major issue with regard to security in a cloud based system. Since anyone can access data from the cloud as the data may be public, private or sensitive. So concurrently, many cloud computing users and providers access and modify data. Thus there is a need of some mechanism to ensure data integrity in cloud computing.
2. Data Loss and Leakage: Data loss is a common problem in cloud computing. Data can be lost or damaged due to miss happening, natural disaster, and fire and there will be a loss of information. Data is always in danger of being lost or stolen by unauthorized access. Due to above situation, data may be inaccessible to users.
3. Data Confidentiality: Confidentiality means that only the authorized and intended users are given permission to access the data. Cloud Computing system offers applications and infrastructures which operate on public networks. Therefore, maintaining confidential data of user’s secret in the cloud is a necessity.
4. Losing control over data: Exporting data means losing significant control over data. Large organization don’t want to run a software delivered in the cloud that risk their data through interaction with some other software
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.
I am a plate that is made of clay that was taken from the Earth of Japan. But before I was made into a plate I was up to the mountains near a big forest that had a Jinja on top a beautiful waterfall where water fell from the top to the bottom and sometimes flowing to rivers. But when winter comes the waterfall would freeze into shards and when the winter goes the shards and snow turn into water filling up the waterfall making a waterfall from the top to the bottom flowing with an immense amount of water to rivers and ponds that would sometimes connect with the waterfall. My maker crafted me to be used as art depicting many natural objects or buildings even sometimes people in the drawing. I am also used to hold a meal for a person who would eat the nourishment from top to bottom. Most of the time I would have fish from the ocean or rice that was farmed in flatlands on top of me.
Upon graduating from Midshipman’s School for Women, Hopper immediately received a task to the Bureau of Ordnance Computation in Harvard University. At that time, when she was around 37-38 years old, Hopper had visited Cruft Laboratory, and she was introduced to a machine that had computing capability called the Mark I. Hopper’s task was to program the Mark I, so it could produce "the coefficients for the interpolation of the arc tangents by next Thursday." Due to this short deadline, Hopper was quite horrified, so she asked some of her colleagues for assistance. Soon enough, she was able to complete this difficult task, and she was the third person to program a large-scale digital computer. In 1945, Hopper had discovered that a real moth
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.
The healthcare industry has access to a patient’s personal health information, in electronic and paper form, and is responsible for protecting this information. The Health Insurance Portability and Accountability Act (HIPAA) establish requirements for the healthcare industry. The establishment and implementation of an effective information security plan is critical to meet these requirements and ensure this protection. There are however challenges and risks that must be addressed. Cloud computing can be defined as the use of computer resources without the expense of owing the hardware and software. Cloud computing is becoming more and more popular in major corporations as a way to gain use of specific programs, applications and even hardware by way of the Internet.
If organisation’s sensitive data and intellectual property resides on public cloud then it is strongly advisable to implement strong encryption techniques. The threat of data tampering is at its highest when data is being processed in the cloud. Essentially, this is because when data are
When they wanted to save photos online instead of on your personal computer, they are able to use “cloud computing” service. Cloud computing means that the transfer of computing data or information over the internet. Not just to keep data in your personal computer, they are able to save the data on internet server to open their data in any computer. In this report we will walk through about what is cloud computing, what kinds of model did cloud computing have, types of cloud computing, benefits of cloud computing, and security.
Based on the payment system, cloud computing is defined as a pay-per-user or subscription based service that broadens its current capabilities and structures. In the networking field, cloud computing is comparable to grid computing, where computers in a network with idle processing cycles are harnessed to work out problems or issues that are too exhaustive for accomplishment by a single machine (Knorr and Gruman, 2011). In cloud computing, the shared IT infrastructure involves a network of servers that operate through virtualization to perform high quality and highly intensive computing processes and tasks. Using web terminology, cloud computing is the storage and data processing via the use of a web browser, rather than the direct use of the personal computer or office server. Therefore, it can be described as the provision and acquisition of information, ...
In the 1950s Cloud computing started with mainframe computing, where multiple users were able to access a central computer by using a dumb terminal, which had only one function, and that was to provide access to the mainframe. In the 1970s, the concept of virtual machines was created, by using the virtual machine technology it was possible to used more than one operating system simultaneously in a secluded environment. In 1993 cloud computing reached its first milestone with e-mail, which is a method of exchanging information/ data or digital messages through a computer network of the internet. Emails were originally a text based form of communication only, these days’ files like multimedia, images or PDFs can be attached. Today, cloud computing is a part of our everyday lives, we still use it to email, and now we use a more perfected cloud system to store applications or files and can access them anywhere and anytime.
Despite the numerous advantages offered by cloud computing, security is a big issue concerned with cloud computing. There are various security issues and concerns associated with cloud computing, among them being phishing, data loss and data privacy. There are different mitigation measures that cloud pioneers are currently using to ensure data stored in the cloud remain secure and confidential as intended. Encryption is one mitigation method used to ensure security in cloud computing. According to Krutz and Vines (2010), encryption involves coding of the data stored in the computing cloud such that hackers cannot gain access to the data. Data encryption seems to be the most effective method of ensuring security in computing (Krutz and Vines, 2010). However, it is of paramount importance to note that encrypted data is usually difficult to search or perform various calculations on it.
Cloud storage basic terms, is a way to save information to the web that can managed data storage. Cloud computing services are online services, which store this information to a safe and secure location online. It’s offered a quicker, easier and safer backup than conventional methods of file storage such as bookshelves or cardboard files.
In cloud computing, the word cloud is used as a metaphor for “the internet”. So the cloud computing means “a type of internet-based computing”, where different services such as servers, storage and applications are delivered to an organization’s computers and devices through the internet.
