drive-by downloads Drive-by downloads are downloads to the computer that are harmful, and are downloaded because the user doesn't know that the download took place, what was downloaded (virus, malware) or downloaded something, but didn't know it was malware. When a malicious website is visited, malware may be downloaded to the computer without users even knowing. Solutions to prevent drive-by downloads include having the internet security suite (like Norton Internet Security) installed and kept up to date. Also, using a proxy can filter the web content (like Vidalia). The user's antivirus firewall should always be turned on. http://www.softwarenewsdaily.com/2010/12/drive-by-downloads-malware-installed-without-your-knowledge http://www.associatedcontent.com/article/794101/how_to_prevent_driveby_downloads_.html Clickjacking Clickjacking, also known as user-interface (UI) redressing, is one of the most common attacks against users by creating malicious pages that tricking users to click on buttons and links which reveal sensitive information, or can allow the attacker to take over control of the user's computer. The true function of the button is hidden under an opaque layer that shows something different to trick the users. A possible solution to clickjacking is the "walled garden" that iPhone has. It has a closed or exclusive set of information services provided for users, instead of allowing open access to apps and content. https://www.owasp.org/index.php/Clickjacking Targeted brand attacks on social networks Targeted brand attacks on social networks is attacking the big brand names, and attacking its reputation, currently common through attacks on social networks and phishing. Scammers that hijacked a social networking account can add random people to their friends list, and link them to malicious sites. Or an attacker would disguise themselves as the "official" profile of the brand company, and make friends and trick them into revealing sen

Describe NoSQL and its purpose. Explain how it is used differently than MySQL. M12 jan30 az

Describe NoSQL and its purpose. NoSQL is a highly scalable and reliable non-relational databases designed to maintain high performance and to be highly cost efficient for workloads of any scale, from the smallest to the largest internet-scale applications. It is also used to build a new kind of database for "unstructured" information that comes spilling off the Internet with each passing second. It is capable of handling large amounts of data du to the fact that they use flash storage rather than traditional spinning disks. These solid-state drives can provide single-digit millisecond response times. Explain how it is used differently than MySQL. MySQL database is a relational database that stores data in neat rows and columns, and it's designed to run on a single machine, while NoSQL database can store data in a more flexible way and is designed to scale across a very large number of machines. "SQL databases are like automatic transmission and NoSQL databases are like manual transmission. Once you switch to NoSQL, you become responsible for a lot of work that the system takes care of automatically in a relational database system. Similar to what happens when you pick manual over automatic transmission. Secondly, NoSQL allows you to eke more performance out of the system by eliminating a lot of integrity checks done by relational databases from the database tier. Again, this is similar to how you can get more performance out of your car by driving a manual transmission versus an automatic transmission vehicle." http://stackoverflow.com/questions/2559411/sql-mysql-vs-nosql-couchdb

Describe the IT systems. Az nov 22

The IT system in this article is software that lets you restore your whole system back on the old or new computer in case your computer dies. But first, you need a "bootable disk". If your computer won't start, insert the bootable disk and the operating system will find it and start up. Second, you need to backup your computer to an external hard drive or DVD before it died. Then, you can use this software called "Acronis True Image Home 2011" that put Windows and all your programs, files and settings, onto a different computer without any hardware conflicts. True Image also comes with a "Try and Decide" mode where you can try any program that is stored on your external hard drive and decide whether you want to keep it on your new computer. Acronis True Image Home also comes with online backup, which is free for 2gb and it makes a bootable disk for you.

The security of the users' sensitive information is at risk when users click on spam links no matter from what source, from e-mails (which are decreasing now) to Twitter tweet links. By clicking onto these harmful links, users set free spam that can infiltrate the user's hard drive in search for sensitive information for example bank account numbers. 4.Describe the relationship of the main stakeholders to the IT system. ---The main stakeholder will be hackers and people who are using e-mail and social networking. The relationships between them are, normally hackers used spam mail to spend virus or hack their computer with Trojan horse, but as the email security develop hackers slowly moved to social network which is Facebook, and other many programs. They know that people are currently using social networking a lot and their privacy is open and they could easily get people's email too.

Android is widely accepted as being iOS' greatest rival, but, according to Dell SecureWorks security researcher Timothy Vidas, it has a host of issues that have made it a target for malware authors. Poor permissions: the huge host of permissions that users must understand are driving them into information paralysis; they are choosing to ignore the warnings presented to them, and not considering whether they may be dangerous or unnecessary. Open marketplace: Google Play does have an automated scanning program called Bouncer, but its effectiveness is as yet unknown. Therefore many Russian and Chinese alternative markets basically distribute 100 per cent malware Inexperienced or malicious developers: if they don't have any malicious intent, the developers could introduce new vulnerabilities into the target device, or create features that have unintended side effects.

- this technology is that the normal video communicate that by the internet to connect to each other. For example, Skype, or Facetime etc. Advantages and disadvantages. - The advantage is that when children want to learn some music but parents don't have time to drive them to the music school, they could have lessons at home which is easy to do. - The disadvantage is that we need many thing to learn via computer, for example, webcam or video camera, good quality speaker, good quality microphone etc.

Why are batteries environmentally hazardous? Because lithium batteries contain metal that will spontaneously ignite if exposed to air. Also, the negative and positive poles on some lithium batteries are close together, leading more easily to short circuit which can cause fire. Explain the issue of safety versus cost. The issue of safety here is that if the lithium batteries are improperly package, damage or have manufacturing defects, they can short circuit and ignite. Overheated lithium batteries can blow the lids off steel shipping containers and damage a plane. Once a battery catches fire, the heat can set off other batteries. Obama administration proposed rules but they are opposed by many because they say the rules would cost them hundreds of millions of dollars in added packaging, paperwork and training for employees. It will also mean delays in getting medical equipment to patients and would drive up the cost of shipments.

Does the Net allow more freedom or is it a tool for governments and businesses to control us? The Net allows both. The users can roam freely to their discretion where and what they want to put onto the web. It is just a matter of a country censoring the content, or the user self-censoring what is to be put on the web. Also, the governments and businesses both can use the Net to their advantage. The government can learn and find out various information of various individuals and trends of the public through the Net's social networking websites and other portal that have discussion between citizens themselves. Business are able to keep track of trends to see what is happening, such as the stock prices to what people like to eat, listen to, what they like to use. Thus the businesses are able to stay in business a little easier through knowing the information from the web. The businesses can also advertise themselves through the net, and that way, it is actually faster than having actual offline campaigns and advertisement. Therefore, the net can allow us both. We are free to use it more than let it control us. It's just a matter of fact that higher class society, social ranking, or economic status-ed has more chances to controlling the net due to their connections with the higher ups. Yet, censorship and surveillance is everywhere, and thus doesn't allow absolute freedom.

What does cloud computing deal with? Describe each of the characteristics cloud services must have. Explain horizontal and vertical services. Define each layer of services. Explain the infrastructure capability terms. Why is bandwidth important? march 17 cream

What does cloud computing deal with? Cloud computing deals with all the technology and support for the infrastructure of the cloud such as networking, database, storage, and management applications. Describe each of the characteristics cloud services must have. Fshared services (with standard framework and shared application programming interface (API)) - these services can be shared in order for all users to have access to them. Fstandard user interface - Web browsers to have access to the cloud services. Fself-service - Users must help themselves by self service when it comes to doing cloud services since actions are carried over the computer, not from human to human. Fservice metering - The Charge of the usage of the cloud services. Faccess over the internet - The medium of having access to the internet, as well as other places over the internet. Explain horizontal and vertical services. Horizontal Services - cloud applications, cloud storage, cloud servers, and cloud collaboration. These horizontal services are the services that are spread around horizontally as the infrastructure, and the base of the cloud service. It provides the technology and memory for clouds for example. Vertical Services - government services, cloud entertainment, cloud publishing and online ad networks, cloud healthcare, and cloud telecommunications. These vertical services are basically what we use the cloud services for, which field they are in, and how they are used. Define each layer of services. Infrastructure as a Service (IaaS) - This is a service usually from outsourcing done by an organization so that the actual infrastructure to hold the storage, hardware, and other components are stored elsewhere. Why is bandwidth important? Internet bandwidth will drive the popularity of cloud services in the country, as businesses and consumers will demand more services as bandwidth increases. Speedy network reliability is needed for "megabit-per-second" services.

What are the problems with doing everything on the cloud? may 19 az

Doing everything on the cloud is efficient in a way that we can work on from anywhere anytime as long as we have internet connection. However, when we don't have good internet connection, there is nothing we can do since everything we have done is stored on the cloud. . Internet data storing plans might also be an obstacle while operating on the cloud because the costs increase as more data is wanted to be stored on the cloud. Moreover, The cloud is not invincible to attacks so your data is not 100% safe. Having a backup saved on a physical hard drive is a must, cause you can't rely too much in the cloud (look what happen to Amazon and Sony).
