TasksThere are ten (10) tasks, one for each week: the tasks are detailed below. There is atable to complete for each task. Please fill in the information required. Note: Each resource summary should be around 200-300 words.Week 1The text discusses how modern CPUs function. Recently a critical flaw in microprocessor design has been discovered that allows two extremely serious security exploits: Spectre and Meltdown. Find and summarise ONE resource that describes how either of these exploits work. The resource (and your summary) should focus on what is occurring in the CPU that allows these exploits to occur.Title: Exploit of Spectra and MeltdownReference: Meltdownattack.com. (2018). Meltdown and Spectre. [online] Available at: https://meltdownattack.com/ [Accessed 12 May 2018].Summary:The main focus point which is related to the topic is that how the meltdown and Spectrebasically exploits the security of a system. The above resource is selected due to the aspectthat it explains in basic language about the two security vulnerability.Meltdown can be considered as an isolation which is related to the user application and theoperating system. The main focus point of the attack is to allow the program to directly accessthe memory and thus allow the secret access to the operating system and other programs. Ifthe user’s system has a processor which is vulnerable and the system is unpatched it is notsafe to work with the sensitive data due to the factor that the attack which is related to themeltdown can easily access the system.Spectre on the other hand is a concept of breaking of the isolation which is between differentapplications. It directly allows the attacker to trick program which are error free which followthe practice into the secret leaking. It can be stated here that the checks of the securityrelating to the best practices directly increase the surface area of the attack and make theapplication more susceptible to the attack of the spectre. Spectre can be considered to be harder to exploit than meltdown on the other hand harder tomitigate. Software patches are very much available which would be preventing the system ofthe user from the exploits which are based on spectre. Week 2Prior to 1985, there were very few Operating Systems (OSes) that used Graphical User Interfaces (GUIs). Find and summarise ONE resource that describes ONE of these GUI operating systems. The OS must have been release prior to 1985 so cannot be Microsoft Windows. Title: GUI Operating systemReference: Templates, B. (2018). List of GUI-Based Operating System and Its History. [online] E-techinnews.blogspot.in. Available at: http://e-techinnews.blogspot.in/2012/06/list-of-gui-based-operating-system-and.html [Accessed 12 May 2018].Summary:The main aim of the article is to take into consideration all the GUI (Graphical user interface)operating system. The main selection of the resource is due to the factor that is gives a broadidea of all the GUI based operating system and indulge the aspect with history involved into it.
The Mac OS system 1.0 can be considered as one of the GUI which is operating systembased which was basically developed for the Macintosh. Some of the features which arerelated to the modern day operating system was involved into the concept. This is due to thefactor that each of the window is accompanies by the help of an icon. The main functionalitywhich was related to the concept was that each of the window can be moved with the help ofthe mouse and it was not restricted to the windows but also the folders, files could be copiedby a way of simply dragging and placing them in a place which is appropriate for the users.This application was applied by the Apple and it can be considered as one of the optionsrelating to OSX snow leopard. The concept can be stated to be making the concept of theMAC simple if it is compared with other types of GUI and became an operating systemclaimed to have one of the best GUI system when it is compared to other operating systems.The security aspect of the data is dealt very well in this concept. Week 3Low-Powered Wide-Area Networks (LPWANs) are wireless communication networks that are characterised by linking devices over large distances. Devices (including simple sensors) typically can only communicate at very low bit rates, however, the communication and associated electronics consume very little power. As such, LPWAN devices can be battery powered and operate independently for many months or even years. Find and summarise ONE resource that describes ONE platform or technology that implements a LPWAN. Title: Technology that implements a LPWANReference: Bhatia, R. (2018). What is LPWAN and why is it considered critical for IoT?. [online] IoT India Magazine. Available at: https://www.iotindiamag.com/2017/03/lpwan-considered-critical-iot/ [Accessed 13 May 2018].Summary:The main justification which can be given in regards to the selection of the resource is that itgives a precise overview of the concept of the LPWAN and how it can be implemented in thetechnology of internet of things. The focus point is how the technology gets its advantagefrom the LPWAN concept. LPWAN fuels up the direct connectivity which is related to the internet of things devices. Thebasic need of the device can be considered to be less bandwidth which is directly applicableto most of the devices which are standard devices. The defining characteristics which areadded to the concept of the internet of things are the high speed connectivity rather thanbeing robust and scalable for the devices which are considered to be smart for examplelighting, sensor etc. these types of setting are ideally used in industrial setting. The concept ofthe LPWAN technology is directly devices to be connected with the range of 15miles and dueto this aspect it is widely used in the concept of the IoT health care sector, utility sector,building and transportation. LPWAN can be considered to be threatening the licensed, cellularnetwork and has a focus of redefining the IoT sector. The Low power wide area network inthe concept of the IoT can be stated to be one of the hottest topic and there are manyresearch being implemented as the technology can be stated to be one of the most costeffective technology which can be easily be implemented and taken advantage. Week 4Voice over IP (VoIP) is a group of hardware and software technologies that allow users to communicate via voice and video over the Internet. VoIP uses a number of different softwareprotocols, depending on the application. Find and summarise ONE resource that describes ONE of these VoIP protocols.
