... Professional Standards Week 8 Marcus Allen The questions asks what are Meta tags and how are they used to promote accessibility and search engine optimization? Meta tags are HTML source codes that are used in headers on web pages. They are mostly used to provide search engines with keyword tags to describe a website’s description and keywords. The most important aspect of Meta tags that allow a search engine to determine what the website should be searched and crawled for would be the description and also the keywords. The other Meta tags give the web browsers and the search engines what is called spider instructions or data on various information. Meta tags are a great way for webmasters to let search engines know about their websites and this is what it would look like. <meta name=”description” content=”A description of the page”/> The other question we are asked would be what is the professional standards in web development and what are some examples? The importance of professional web standards in web development allow not only users but also designers to interact easier and not have different rendering issues with non-compliant browsers. with all the different browsers and each having incompatibility all designers struggle to ensure web browsers look the same in various web browsers. With professional standards in web development the HTML code could have been in the same manner no matter the platform...

Has widgets, increasing clients’ desire on the operating system. Google chrome is the default browser in android when it comes to internet access, however, other browsers such as opera mini and Mozilla firefox.Android is independent on the device it is being runon. Mostly found in devices such as Sony, Huawei and Samsung in different versions like gingerbread and lollipop. Mostfeatures cannot be customized by user .IOS is also independent on the device it is being run on. IOS kernel is usually not open source and thus difficult to root a phone running on iOS. Different versions are available such as iOS5.0 and iOS 7.1Available in devices such as ipones, ipads and ipads .IOS has no widgets but a dock where most frequently applications are used.IOS is available in 34 languages unlike androids 32 languages. Mobile safari is the default browser for the iOS.Third party browsers are available in the apple app store due to differing users taste. In a nutshell, both iOS and android are quality operating systems and developed to be used in touch interfaces. In both os there is a status bar displaying shortcuts of key features such as Wi-Fi and Bluetooth. They both are excellent operating system and decision is determined by the...

Available from: http://linux.about.com/cs/linux101/g/interactiveproc.htm. (Accessed 14 July 2010). 2. What complications could arise in a time-sharing system if two processes require access to the same file at the same time? Are there cases in which the file manager should grant such requests? Are there cases in which the file manager should deny such requests? If two processes require access to the same file at the same time, two main situations could arise: 1. Both processes attempt to read the file in which there is no harm. If the file is used as merely input for the processes and is not being changed then this is ok such as in the case files that contain instructions. 2. One or both processes attempt to update the file can lead to data corruption and or deadlocks. Picture the processes are depending on information in the file that goes in a sequence 1, 2, 3, 4, 5. Process A begins to read the first and gets to 3. At that time Process B starts and gets to 2, but process A is making...

...The browsers that I use are Google Chrome and Microsoft Internet Explorer. For this class, I mostly use Internet Explorer due to its compatibility with Blackboard vs. Chrome. At one time, I used Mozilla’s Firefox; however recently, I have found issues with the browser getting a little sluggish and decided to completely go to Chrome and save IE for when I absolutely could not use Chrome. Chrome has become a very well rounded browser from when it started. Currently, the version of Internet Explorer that I use is 9.0.8112.16421 and upon a quick check, it is the most current version. Internet Explorer 9 has anti-phishing and anti-malware functionality. In Internet Explorer 9, the functionality is called SmartScreen filter. To check if it is turned on, you click your settings (or tools) icon, scroll to safety, and click Turn off (or on) SmartScreen Filter. This will launch the tool that allows you to select whether the setting is on or off. I believe this is a great feature of Internet Explorer 9 and my SmartScreen filter is always turned on. In addition, you can double check a suspicious site if you feel that SmartScreen missed it by going to tools, safety, check this website. In addition to the SmartScreen filter, my Internet Explorer 9 browser is also set to block pop-up windows. There are a couple exceptions that I have added to the pop-up blocker which include the Pima Blackboard site and my corporate VPN site. To get to the settings for Java, I go to my Control Panel.

...computers and terminals, expanded to point-to-point connections between computers and then early research into packet switching. Packet switched networks such as ARPANET, Mark I at NPL in the UK, CYCLADES, Merit, Tymnet, and Telenet, were developed in the late 1960s and early 1970s using a variety of protocols. The ARPANET in particular led to the development of protocols for internetworking, where multiple separate networks could be joined together into a network of network 3. Internet vs. internet? - one existing distinction between "Internet" and "internet" has been around for a while and fills an important role when discussing related technology. some of us use "Internet" (pronounced "Big-I Internet") to refer to the global network which is mostly connected, at least at the IP layer, and can forward IP packets from sources to destinations (NAT boxes ignored for now). we then use "internet" (pronounced "little-i...

...external penetration test (Cobb,2014). 2. What is a cross-site scripting attack? Explain in your own words. Cross-site scripting is when an attacker exploits the controls of a trusted website and injects malicious code with the intent of spreading it to other end users. For example, an attacker injects a browser script on a website, so that other users will click on it and compromise sensitive information. 3. What is a reflective cross-site scripting attack? A reflective cross-site scripting attack is when the injected script is reflected off the web server, much like an error message or search results. This type of attack is mostly carried out by e-mail messages in which the user is tricked by clicking on a malicious link and then the injected code travels to the vulnerable website and reflects the attack back to the user’s browser (OWASP, 2013). 4. What common method of obfuscation is used in most real-world SQL attacks? These methods include character scrambling, repeating character masking, numeric variance, nulling, artificial data generation, truncating, encoding, and aggregating. These methods rely on an array of built in SQL server system functions that are used for string manipulation (Magnabosco,...

...There are a variety of ways and innovative techniques used by attackers to exploit the weaknesses of the Internet. Some techniques are simple to construct while others are more complex and creative. Attack techniques are constructed to attack web servers, as well as, web browsers and email applications. Attackers mostly target web servers used for sensitive transactions, such as, banking e-commerce. Security holes may be found in the configurations of hardware and software commonly used, such as internet information ran by Windows. Attackers may use buffer overflow attacks or two types of SQL (Structured Query Language) injection attacks to access web servers. Buffer overflow is used to exploit vulnerabilities within software. Software customized for companies are more difficult to attack so they have less vulnerabilities. On the other hand, commercial software, webservers and databases are more susceptible to buffer attacks. Attackers discover poorly written code then inject malicious code causing buffer overflows. To discover any codes they must first access the code structure and find the weaknesses and errors located in the source code which is how buffer overflow attacks begin. The source code may be wrapped in a “black box” which provides protection from tampering, however, many attackers have the skills need to access the code nevertheless. There are different buffer attacks that can be used by attackers. A stack-smashing attack usually aims at the critical buffer...

...significant amount of increase in the quantity of Internet users around the globe. Due to such significant amount of increase in the number of users, the attackers are targeting the application layer protocols like SMTP, HTTP, DNS, SNMP and many others. HTTP is an application layer based protocol used by World Wide Web which is primarily responsible for what actions a Web Browser of Server should undertake in reply to the varied commands from the users. This is a protocol for distributed, collaborative, hypermedia information systems, thus making it by far the dominant traffic source in IP networks. Thus due to this rapid expansion and...

...1. 1. MD5 weaknesses/Creating a rogue CA certificate è The first article mostly talks about the weakness of MD5 hashing algorithm by giving a couple of examples that why MD5 is easy to break. The first example was Microsoft’s windows update. The flame espionage malware created a counterfeit certificate based on the same MD5 hash then computers starts to download malwares instead of updates using the legitimate credential. This is how it was easy to spread over millions computers using Windows operating system. Since then Microsoft started to use SHA1 instead but this is also believed to be broken in near future. Second example was stating that there were two images with one MD5 hash. This could be done by adding near collision blocks repeatedly until the two hashes become the same. This is the main flaw of MD5 which is MD5 collision. One reason that we need to pay attention to this problem is that this could be done within ten hours using Amazon Web Service paying only $0.65 plus tax. These...

...1989: Tim Berners-Lee invents the Web with HTML as its publishing language The World Wide Web began life in the place where you would least expect it: at CERN, the European Laboratory for Particle Physics in Geneva, Switzerland. CERN is a meeting place for physicists from all over the world, where highly abstract and conceptual thinkers engage in the contemplation of complex atomic phenomena that occur on a minuscule scale in time and space. This is a surprising place indeed for the beginnings of a technology which would, eventually, deliver everything from tourist information, online shopping and advertisements, financial data, weather forecasts and much more to your personal computer. Tim Berners-Lee is the inventor of the Web. In 1989, Tim was working in a computing services section of CERN when he came up with the concept; at the time he had no idea that it would be implemented on such an enormous scale. Particle physics research often involves collaboration among institutes from all over the world. Tim had the idea of enabling researchers from remote sites in the world to organize and pool together information. But far from simply making available a large number of research documents as files that could be downloaded to individual computers, he suggested that you could actually link the text in the files themselves. In other words, there could be cross-references from one research paper to another. This would mean that while reading one research paper, you could quickly...

This browser was recently released and has met with considerable success- it has been downloaded more than 20 million times and has already taken considerable market share from its prime competitor- Microsoft’s Internet Explorer. In this paper, I chronicle how the efforts of 63000 volunteers led to a community successfully competing with a powerful corporation. I identify four factors as the key facilitators to Firefox’ success- complacent competition, product superiority,...

...person or organization without their knowledge and that may send such information to another entity without the consumer's consent, or that asserts control over a computer without the consumer's knowledge.[1] "Spyware" is mostly classified into four types: system monitors, trojans, adware, and tracking cookies.[2] Spyware is mostly used for the purposes of tracking and storing Internet users' movements on the Web and serving up pop-up ads to Internet users. Whenever spyware is used for malicious purposes, its presence is typically hidden from the user and can be difficult to detect. Some spyware, such askeyloggers, may be installed by the owner of a shared, corporate, or public computer intentionally in order to monitor users. While the term spyware suggests software that monitors a user's computing, the functions of spyware can extend beyond simple monitoring. Spyware can collect almost any type of data, including personal information like Internet surfing habits, user logins, and bank or credit account information. Spyware can also interfere with user control of a computer by installing additional software or redirecting Web browsers. Some spyware can change computer settings, which can result in slow Internet connection speeds, un-authorized changes in browser settings, or changes to software settings. Sometimes, spyware is included along with genuine software, and may come from a malicious website. In response to the emergence of spyware, a small industry has sprung up dealing...

...The operating system that we use on our computers is the most important program that we have. Every computer used for home or business must have an operating system to run other programs. They perform basic tasks and recognize the input from the keyboard and output to the display screen. They keep track of files stored on your computer and control disk drives and printers. (Beal, N.D) There are five basic functions of an operating system. They are: * Booting the computer * Performing basic computer tasks like the mouse and keyboard * Provides a user interface such as a command line or a graphical user interface * Handles system resources such as a computer’s memory * Provides file management which is the way the operating system manipulates, stores, finds and saves data (N.A., N.D.) The difference between Windows, Linux and Mac OS is that windows is designed to run on PC’s. All three are operating systems, but the internal architectures are different in each. And PC’s are very inexpensive for a basic model. (Sinoun, 2011) The Windows operating system is pretty versatile, and can be installed on PCs having variable amounts of resources. There are versions of Windows that can be installed on PCs having as little resource as 233 MHz processor and 64 MB RAM. Windows users get good choices for their operating systems, based on the system resources they have. An even greater benefit of Windows users is the user-friendliness of the operating system. The graphical...

...the past, the concept of bots did not include harmful behavior by default.Bots can be very benecial programs when they are designed to assist a human user, either by automating a simple task, or by simplifying a user's control over various programs or systems. Botnets are used for malicious activity like distributed denial of service attacks, identity theft, sending spams and phishing attacks. Typically botnets used for illegal purposes. Botnets are seen to be one of the main sources of malicious activity. Rapidly growing botnets and new methods for spreading malicious codes and launching attacks. Bots sneak into a persons computer in many ways. Bots often spread themselves across the Internet by searching for vulnerable, unprotected computers to infect. When they nd an exposed computer, they quickly infect the machine and then report back to their master. Their goal is then to stay hidden until they are instructed to carry out a task.The very nature of botnets gives criminals plenty of power on the internet at large. With control over so many compromised systems, herders can now engage in quite more damaging activities than the internet has seen before. After a computer is taken over by a bot, it can be used to carry out a variety of automated tasks. Bot sends spam, viruses and spyware. They steal personal and...
