...As the Security Engineer of my employer I have been asked to analyze some potential malicious threats that are arising in our organization and explain the possible impacts. Therefore, I start to monitor the incoming and outgoing traffic in the network. It didn’t take too long to come across a active attack. Someone was trying to bypass or break into our secured system. The intruder was able to bypass our first layer firewall and then was stuck trying to access a specific IP range specific to our servers which hold hundreds of credit card information. We have been investigating and back tracking this threat with some forensic tools. It is difficult to back trace the intruder now that the connection has been broken. A few days passed when then someone brought to my attention that he received a phone call from someone stating they were from Microsoft and needed to run some updates on the employees workstation. The employee gave out his IP address so that the person from Microsoft can remote into the workstation. The employees workstation was compromised therefore the Desktop team has retrieved the workstation and started to trace anything that the person might have done while connected remotely. After the desktop support team did intense scans they did not find any malicious software installed or running the machine. They are checking on any possible data they might have viewed or accessed that will make them attack again or provide them with the information to cause the company...

...Introduction This document contains information on the various factors from the user and the server of a website, and their overall effects on the performance and running of the website. It will include the individual effects of each piece of hardware and what it does to help with the performance of the webpage. The effects of malicious entities like viruses and botnets and how they affect the server and its running. User side factors that influence web performance Viruses: If the user’s computer is infected with a virus it is able to reduce the speeds of the internet connection and can overload the processor so it works harder. This then has to calculate the information for the website and other task it has been forced upon by the virus causing loading times to increase. Each virus falls under a different category, each category does a different type of malicious activity. Trojan horse in computing terms is a non-self-replicating malware program that contains malicious coding. This program, when it is executed by the user will carry out various tasks that have been determined the Trojan’s nature. Trojan’s are typically used in a way such that the victim suffers from data loss, data theft, and even possibly damage to the system. Trojan’s can infect the victim’s computer for a various number of reasons. The virus is able to force the machine into a botnet system which is part of DDOS attack. Some attacks that can be unintended or used out of pure intent of being malicious...

...consultant, I would be more than willing to help you with your upgrade. The information below will describe the best options for your office. I would upgrade the operating system to Windows 7 Professional, since your network is built around a Windows domain; this is the least expensive Windows 7 edition that can join a domain. This edition also includes the capability to allow Remote Desktop access to your computer from the network. The Windows backup program offers the same set of features in all editions, however Professional edition adds the option to store backed-up files and system images to a network location instead of limiting you to local hard drives and removable media. Without actually having the programs running you will use an average 40% of 4GB of memory if you use the user interface enchantments. Microsoft requirement are: 1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor 1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit) 16 GB available hard disk space (32-bit) or 20 GB (64-bit) DirectX 9 graphics device with WDDM 1.0 or higher driver BitLocker helps keep everything from documents to passwords safer by encrypting the entire drive that Windows and your data reside on.

...Storage TG1.5 Input/Output Devices TG1.1 Components of a Computer System Computer hardware is composed of the following components: central processing unit (CPU), primary storage, secondary storage, input devices, output devices, and communication devices. Communication devices are covered in detail in Tech Guide 4. The input devices accept data and instructions and convert them to a form that the computer can understand. The output devices present data in a form people can understand. The CPU manipulates the data and controls the tasks done by the other components. Primary storage (internal storage that is part of the CPU) temporarily stores data and program instructions during processing. Secondary storage (external storage such as flash drives) stores data and programs that have been saved for future use. Communication devices manage the flow of data from public networks (e.g., Internet, intranets) to the CPU, and from the CPU to networks. A schematic view of a computer system is shown in Figure TG1.1. REPRESENTING DATA, PICTURES, TIME, AND SIZE IN A COMPUTER ASCII. Computers are based on integrated circuits (chips), each of which includes millions of sub-miniature transistors that are interconnected on a small (less than l-inch-square) chip area. Each transistor can be in either an “on” or an “off” position. The “on-off” states of the transistors are used to establish a binary 1 or 0 for storing one binary digit, or bit. A fixed number of bits representing specific...

...Part 1 1. What is the difference between interactive processing and real-time processing? Interactive processing is when there is a continuous exchange of information between the computer and user whilst performing tasks. Examples include entering information into a query in a database or information into a word processor. Real time processing means that there is a continual input, process and output of data. It may be a situation whereby a user sends in transactions and awaits a response from a distant computer before continuing. We see this happening when we use telephone banking to transfer funds from our savings to our credit card and the money is accessible immediately. Real Time Processing [Online]. Available from http://www.answers.com/topic/real-time-processing-e-business-term. (Access 14 July 2010). Interactive Processing [Online].

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...

...SSD have been around for over 30 years. They haven’t been commonly used by manufactures, until recently when they have been recreated and used in portable devices such as Ipad and iPhones. This has to do with the expense of the SSD’s. Prior to the SSD manufactures have been using the Hard Disk Drive (HDD), which is designed completely different. HDD,s use a rotating disk which is accessed by a mechanical actuator, which SSD’s use nonvolatile memory. This makes for less moving parts and makes the SSD less fragile. SSD’s are used in smart phones and digital cameras. We know them as secure digital cards (SD cards) and flash drives; these are less complex versions of the SSD. The difference of a SSD and the version that is used in our mobile devices is the performance requirements. The memory needed for a digital camera is less demanding than what a multi core possessor laptop or a data server would need. More complex versions of the drives are made up of 3 blocks storage media, a controller for managing the media, and a host interface for accessing the media. When is come to comparing the SSD and HDD, they both are made to boot up our systems store applications, and our personal files. Booting up a SSD it will boot in seconds while a HDD takes longer because it has to spin up the disk to operating speed. HDD’s are also slow when it comes to accessing your files because it has to spin and practically find the file that you are looking for, and they tend to get fragmented after time...
