Abstract The advent of social networking and Internet of Things has resulted in an exponential increase in the volume of data. Simultaneously, the need to process and analyze the large volumes of data for business decision making has also increased. Many business and scientific applications need to process petabytes of data in efficient manner on daily basis. This data is categorized as "Big Data" due to its sheer Volume, Variety and Velocity and has resulted in a problem for the industry due to the inability of conventional database systems and software tools to manage and to process the big data sets within tolerable time limits. The scale, diversity, and complexity of Big Data require new architecture, techniques and algorithms to manage
Ping Sweep and Port Scan Activities Abstract Ping sweeps and port scans has been a notorious and yet a useful tool for hackers and system administrators alike. This paper will examine some of the possible criminal computer activities that can be executed using these two techniques. Ping sweeps and port scans at times can be a nuisance to system administrators. While describing some of these notorious computer activities, these techniques will also be shown how system administrators can use the to benefit the company. Keywords: port scan, ping sweep Ping Sweep and Port Scans Activities With the evolution of the computer technology, system administrator obviously has had to grow with the technology.
Ping sweeps and port scans By Brian E Network security has become an important concern for both administrators and users. The corporate networks of today are the lifeblood of the organization. They move and store vast amounts of information and allow for instant access to that information for authorized users. This information is attractive to criminals and most organizations will have to defend against an attacker attempting to gain access to the network. Two methods an attacker may use to get information and gain access to the network are ping sweeps and port scans.
Why is it important to document change requests? What happens if a development team doesn’t? * Database administrators usually support different business units with each unit having their own set of unique procedural requirements. Formalizing and documenting the change request process minimizes the potential for miscommunication between the business units, application development areas and the database administration unit. This is even more important to remote database services providers, meaning that if an organization doesn’t have a formal change request process in place, they’d have to create their own.
Digital technology is having a huge impact on this. Traditionally, marketing managers would study and research customer trends and offer their opinions based on their experience. However, in today’s digital world, more and more organisations are relying on digital data to gain customer insights. By gathering massive quantities of data on customers buying and spending habits, organisations can now track the customer’s journey from awareness to attitude towards a product, to purchasing and even their loyalty to a product (Leeflang et al., 2014). Technical analysis of customer journeys has become a decisive feature for many digital marketing agencies.
In regards to information security, there are many common sets of policies in place. These policies include acceptable use policies, due care, separation of duties, password management, change management, classification of information. Other important policy-related issues include privacy, service level agreements, human resources policies, codes of ethics, and policies governing incident response (Conklin, White, & Williams, 2012). Earlier, we talked about how human factor is the most critical aspect in information security. Criminals are always searching for newer and clever ways
Ethics in Computer Forensics Investigation Ethical & Legal Issues in the Professions By: Pete Gonzalez Professor: Steven Osburn DeVry University 06/19/11 Computer Forensics Investigation has become a new widely increasing field of forensics investigation. As with any investigative field there comes a time when ethical issues and principles will arise. We can take a look at some of the ethical issues associated with computer forensics investigation. Computer forensics is a tool of collecting, analyzing, preserving, and presenting digital evidences collected from a computer in a legally acceptable manner. The process of computer forensics is thus quite complex and involves various activities.
Common Information Security Threats CMGT/400 August 12,2013 Common Information Security Threats The growth of technology has greatly changed the way that information is offered in a library setting. Libraries have had to rethink the fundamental of how information will be available, as well as the methods that will be used to acquire library resources and services. With technology, security threats arise constantly leading to open vulnerabilities. With the need to leverage technology to produce tailored capabilities for library patrons, the library faces the need to secure the computer systems and networks that allow the safe use of technology within the library. The following excerpt will define some major information security threats, the potential risks to the information, the forces that drive each threat, and the related vulnerabilities in a library setting.
Introduction “Protecting information assets that power enterprise business applications has never been more critical.” (Newman, 2003.) The fastest growing concern in today’s society is information safety. With the increasing use of computers in all aspects of life from work to home, it is no wonder people and businesses are worried about their personal security. Such threats as identity theft, financial loss, hackers, viruses, and unwanted information sharing are a persistent danger for all computer users. So what is there to be done about something that is ever-changing, fast growing, and uncharted?
Recent advance in advances in hardware technology re-kindled the interest in implementing in-memory databases as a means to provide faster data accesses and real-time analytics , , , . Most commercial database vendors (e.g., SAP, Microsoft, Oracle) have begun to introduce in-memory database to support large-scale applications completely in memory , , , . Nevertheless, in-memory data management is still at its infancy with many challenges , , , , and s completely in-memory design is not only still prohibitively expensive, nut also unnecessary. Instead, it is important to have a mechanism for in-memory database that utilize both memory and disks effectively. It is similar to the traditional caching process, which is however the other way around: instead of fetching data that is needed from disk into main memory, cold data is evicted to disk, and fetched again only when needed.
