...Juan Gomez Project Management The FBI’s Virtual Case File Project Failure Back in the years between 2001 and 2005, the FBI had started a project called the Virtual Case File. This was part of a larger initiative called Trilogy which was supposed to contain three parts to it: One was to upgrade software and hardware for FBI agents. Another was to be able to upgrade the FBI’s communications network. And the third in which it contained the Virtual Case File, was to significantly upgrade the FBI’s case management system “to enable better access to, and sharing of, case-related information across the FBI.”(WordPress) The first two parts were able to be completed but the Virtual Case File project was faced with high costs and schedule overruns and thus never achieved its goals. This project was compared to the London Stock Exchange’s Taurus Project, where scope creep lead to the termination of the project after huge amounts of cost overruns. The Trilogy program was to modernize the FBI’s information technology infrastructure. The Virtual Case File was intended to replace the FBI’s antiquated case management application, which was the Automated Case Support system. The Virtual Case File was initially designed to improve the FBI’s ability to manage investigative case files, to facilitate data and document resources, and to share information with other FBI offices. In the beginning, The Department of Justice required the FBI to use two contractors for the Trilogy project because the...

...The article that I read was about the FBI and how it blew $170 million dollars trying to modernize the FBI’s technology. They had a $581 million dollar budget on this transformation which they called “Trilogy”. They referred to this project as “Tragedy” because the new software that they were trying to use which is called Virtual Case File, was not in production and was said to probably never be in production. With that being said, the September 11 attacks dropped a heavy load of pressure onto the project and derailed the course that they were taking on it. I think that the information provided was great considering that this was an FBI project. There was some information that could not be released and some details that could not be discussed. Overall the article was presented in a very professional manner and I was actually kind of surprised that any issues that occur in the FBI could be discussed. It was an article that they could make a one hour show about on television. The one thing that kind of had me confused was how they could have IT workers whom they considered “not capable” of doing what they were asked to do as far as modernizing the technology infrastructure. After years of failure they did ultimately decide to take the project in another direction but to think that they wasted so much money on software that did not hold up, is just crazy. In my opinion, this article was very informational but at the same time it gives a little insight as to just how much technology...

...The FBI started to set up a project to build a new Virtual Case File system (VCF). This VCF project was to be let as one massive contract at a total cost of $379m. It was planned as a classic waterfall project - with a grand design being drawn up before work would start on the development of a monolithic system. Testing would be carried out at the end, and the whole system would go live at once - a classic big-bang implementation approach. Science Applications International Corporation (SAIC) The 9/11 attacks increased political pressure for better homeland security and data sharing between 6 agencies. Responding to this pressure, the FBI made promises to bring forward deployment of the new VCF case management system by 6 months - to December 2002. Then they received an additional $78m of funding and promised to chop off another 6 months from the schedule. The classic symptoms of waterfall project failure started to reveal themselves. Project plans were found to be unrealistic, and the oversight of project spend was inadequate. It became obvious that the project would not meet its accelerated deadlines. A commitment to using unproven thin client technology had been made - and the design for a web-like access to a centralised database was deeply flawed - BUT: up-front contracts with suppliers bound the project to this technology and the testing that could have revealed these flaws came too late to allow a change of direction. After...

...The FBI's VCF (Virtual Case Files) IT project is one of the most highly publicized software failure in U.S history. The main goal of the FBI’s VCF project was to automate the FBI's paper driven work environment, allow agents and intelligence analysts to share vital investigative information, and replace the obsolete Automated Case Support (ACS) system. The FBI outsourced the code writing for the VCF project in the year 2001 to contractor Science Applications International Corporation (SAIC) based out of San Diego,CA. SAIC delivered 700,000 lines of code that was overly bug ridden, and functionally off target from what the FBI expected, that the FBI had to terminate the $170 million project which included $105 million worth of unusable code. Various government audits and independent reports show that the FBI did not have the proper IT management and technical expertise, and should share the blame for the VCF project failure. At the termination of the project in 2005, Glenn A. Fine, the U.S. Department of Justice's inspector general, described the main factors that contributed to the VCF's failure. His list included the following factors: poorly defined and slowly evolving design requirements; overly ambitious schedules; and the lack of a plan to guide hardware purchases, network deployments, and software development for the bureau. The FBI announced that it would buy off-the-shelf software to be installed in phases over the next four years from 2005-2009....

...Digital Evidence Fall 2007, Volume 6, Issue 2 Computer Forensic Analysis in a Virtual Environment Derek Bem Ewa Huebner University of Western Sydney, Australia Abstract In this paper we discuss the potential role of virtual environments in the analysis phase of computer forensics investigations. General concepts of virtual environments and software tools are presented and discussed. Further we identify the limitations of virtual environments leading to the conclusion that this method can not be considered to be a replacement for conventional techniques of computer evidence collection and analysis. We propose a new approach where two environments, conventional and virtual, are used independently. Further we demonstrate that this approach can considerably shorten the time of the computer forensics investigation analysis phase and it also allows for better utilisation of less qualified personnel. Keywords: Computer Forensics, Virtual Machine, computer evidence. Introduction In this paper we examine the application of the VMWare (VMWare, 2007) virtual environment in the analysis phase of a computer forensics investigation. We show that the environment created by VMWare differs considerably from the original computer system, and because of that VMWare by itself is very unlikely to produce court admissible evidence. We propose a new approach when two environments, conventional and virtual, are used concurrently and independently. After the images are collected in a forensically...

...take what we have learned from our course POS/355 Operating systems and research to compare and contrast the UNIX/Linux, Microsoft Windows, and MacOS systems. In particular we will contrast and compare the different operating systems in regards to memory management, processing, file management and security. Operating systems at the core is all about the kernel. The kernel in all of the operating systems is the main component that is responsible in the management of memory, processing, file management and security. Contrast and Comparison of Memory Management within Operating Systems Memory management in comparison and contrasts between the different operating systems is due to the way the kernel works in conjunction with the memory. Since each operating system has different kernel’s they each have similar and different ways that they manage memory. Contrasts and comparisons on Mac OS, Windows, and UNIX/Linux are described below. 1. UNIX: Though UNIX and Linux are extremely similar when it comes to how things work internally; there are slight differences that make UNIX distinct from its counterpart. One process that UNIX utilizes is known as swapping; this is done by moving chunks of the Virtual Memory (called pages), out of the main memory and moving others in. In order for this process to work at its best, those pages that are needed must be accessible in the Main Memory at the demand of the CPU. When a page is expected to be needed in the very near future it is termed...

...was already being done in Linux operating system. With the previous versions, most of the memory management occurred upon login. This slowed the processor down taking up all the resources at one time using the system memory. To address this issue and correct it in Windows 8, Microsoft implemented a start on demand model. What this means is that processes that are needed are delayed until the process is needed verses having all the processes start automatically when the computer is started. This makes more run on scheduled than before which frees up startup memory. According to Microsoft (2013),” Virtual memory combines your computer’s RAM with temporary space on your hard disk. When RAM runs low, virtual memory moves data from RAM to a space called a paging file. Moving data to and from the paging file frees up RAM to complete its work (para 1-2)”. Only the most recent files used are keep in...
