...At 2:40pm MT on 2/17/2016, the Credit LEAD database encountered a row lock. As a result, database connections maxed out, causing the Credit LEAD application to become unavailable at 2:48pm. A restart of the application servers was conducted at approximately 2:55pm, clearing out any row locks in the database. Application service was restored and validated at 3:11pm. Root cause appears to be related to an increased latency causing performance issues with the Credit LEAD application. Reports indicate the application servers had sufficient memory and CPU to handle the database calls. Additionally, the database showed very quick response times. There was a report of increased response times (latency) from 2:40pm to 2:52pm. However, there is no...

For instance, network #1 had intrusive access via a Microsoft ISS web server to cmd.exe, which allowed complete access to the system. This was achieved through a buffer overflow attack against IIS. As such, the administrator of this network should ensure that all systems are fully patched in order to avoid known exploits. For network #2, an exploit via phpBB enabled access to the system. Network #3, “EXPLOI~1.RTF”, which a user must have downloaded, was executed, opening up a backdoor into the system. Unfortunately, as outlined in my conclusion, an in-depth analysis of this data was aborted partly due to time mismanagement and a very large course load for the term. INTRODUCTION This assignment consisted of the analysis of three different networks with their own associated log files and packet dumps. In total, the data to be analyzed consisted...

...Staying Just in Time for the Holidays North Pole Workshops is faced with a multitude of demand planning, production and logistics problems. With just five weeks left until their annual delivery due date, they are under pressure to resolve short-term issues in demand fluctuations and capacity constraints, but Santa and his team are also concerned about the long-term feasibility of delivering cheer to a growing population of believers. North Pole Workshops has room to improve in all areas of the SCOR model; that is, the plan, source, make and deliver functions need to be addressed in order to improve the overall performance of the supply chain. The short-term production issues for this holiday season involve the increasing demand for the Timmy CD and the possibility of a drastic decrease in demand for the Meowrrr. However, Santa’s elves are also aware of increasing demand from China and Eastern Europe, and since those markets are assumed to be unaffected by the negative commentary on the Meowrrr, the excess product can be used as safety stock for those growing regions. Because they already have more Meowrrrs on hand than predicted demand, the production capacity of Meowrrrs can be completely turned over to the other products based on the next trend. This may be the number 2 and number 3 items for that age group (girls 8-15), but they should also do some quick analysis of TV ads in North America to determine any up-and-coming trends in December for that...

...travel time, reliability, safety, comfort and security are also important, as well as environmental impacts. Trucks: In countries where large-scale intercity trucking operates efficiently in medium-income countries with predominantly flat terrain, recent experience is that the transport cost per km for a truck-trailer is between US$0.75 and US$ 1.25. For a typical load of 20 tonnes, this works out at US cents 4-6 per tonne km. By contrast efficient small-scale transport in rural areas using small trucks may have a cost of US$ 0.20-0.30 per tonne-km, although it is common for the rates to be expressed on an hourly rather than km basis. Inefficient operations may push these costs much higher. Main factors that affect trucking costs are • economies of scale in truck size, which favor the use of larger trucks, • back-haul possibilities, which depend strongly on the demand pattern, • empty running and idle time due to seasonal variations in demand, • restrictions on working hours, for example due to regulations or safety reasons, • road conditions such as mountainous terrain, deteriorated pavement and traffic congestion, • enforcement procedures along the road and at border posts, which can delay trucks and impose high unofficial payments, • standard of trucks, in terms of design and condition, which affects speed, availability and consumption rates for fuel, spares and other inputs, • availability of freight forwarding and other services, which is often poor in remote...

...Abstract AAS-Design AAS-Design is a North American fashion label specializing in luxury goods for men and women (ready-to-wear, leather accessories, shoes, luggage and hats), founded in 1990 by Abel, Angus and Satish in Virginia Beach, Virginia. Fulana inherited the company in 1995 by which time sales were up to U.S. $450,000. With John alongside her as business manager, Fulana was allowed time to implement her creativity onto design. Initial success was not instant, as they were hard to sell due to the lack of advertising and high-prices, but later become her first commercial hit. Description of technology and Communications Need: IT Department The IT Department is in the third floor of corporate building. From this place the IT department offer supports to the entire corporate building and the rest of the store in U.S. The implementation of news technology indicates the degree of business transformation varies significantly between firms. Improving processes usually involves implementing systems and process management across business function boundaries rather than within functions. IT infrastructure investments can be a constraint where systems are not compatible, or where inconsistent data models have been used in different parts of the business. (Broadbent, M., Weill, P., Clair, Don St, 1999) As companies grow, their IT Infrastructure evolves, requiring additional capacity and process efficiencies. The IT infrastructure required to support a company's operations...

SQA tools are the specially developed software tools for the purpose of assisting in the QA processes. 1.1 Software Quality The quality of software is assessed by a number of variables. These variables can be divided into external and internal quality criteria. External quality is what the user experiences when running the software in its operational mode. Internal quality refers to the aspects that are code-dependent, and are not visible to the end-user. External quality is critical to the user, while internal quality is meaningful to the developer only. When the quality comes to software quality conformance, requirement consider as software functional quality and fitness for use named as software structural quality. 1.2 Software Quality Assurance Software quality assurance (SQA) consists of a means of monitoring the software engineering process and methods used to ensure quality...

...CIS210 June 16, 2014 By its very nature, the information technology field and all things related to the internet are in a constant state of improvement. Due to the high need to be able to compete in any online market successfully a company needs to be able to keep a secure, working website with an uptime as close to 100% as possible. With the very real possibility of malicious crackers trying to do damage or steal data security is of the utmost importance. One of the best ways to improve security and control is for the company to host their own website internally. The benefit’s for doing this transition will be well worth the effort but there are few points that need to be considered before making the final decision. The goal of this report is to provide information and a guide to the process of creating a secure e-commerce site with minimum downtime. Considerations: There are a few factors that need to be considered before making the move to migrate the website. * Cost-Hardware, labor, software, etc. * Security-physical and physical * Physical space- structure, square footage, additional offices etc. Solution Using the System Development Life cycle we can define an efficient way to meet our set requirements and improve the existing website. Improving on the old foundation we can minimize costs, reduce project time and save the labor costs of having to start from scratch. This way we can focus on only redesigning parts we can’t recycle and improve...

...White Paper Big Data Analytics Extract, Transform, and Load Big Data with Apache Hadoop* ABSTRACT Over the last few years, organizations across public and private sectors have made a strategic decision to turn big data into competitive advantage. The challenge of extracting value from big data is similar in many ways to the age-old problem of distilling business intelligence from transactional data. At the heart of this challenge is the process used to extract data from multiple sources, transform it to fit your analytical needs, and load it into a data warehouse for subsequent analysis, a process known as “Extract, Transform & Load” (ETL). The nature of big data requires that the infrastructure for this process can scale cost-effectively. Apache Hadoop* has emerged as the de facto standard for managing big data. This whitepaper examines some of the platform hardware and software considerations in using Hadoop for ETL. – e plan to publish other white papers that show how a platform based on Apache Hadoop can be extended to W support interactive queries and real-time predictive analytics. When complete, these white papers will be available at http://hadoop.intel.com.
