The main objective of establishing a business organization is to ensure that returns from the venture are maximized. Entrepreneurs must work around the clock for the mobilization of resources and make sure that the business goals are achieved. Various mechanisms are applied to enable the accomplishment of the missions. These encompass the creation of a working environment that is favorable, the adoption of the right technology as well as ensuring that there is the provision of suitable services and products into the market. Any business organization that aims at growing and attain global recognition has to make better consideration of technological trends. Operational data is a requirement for all levels of decision-making in organizations. It is essential because it gives a comprehensive account of any transpiring aspects. The inclusion of technological solutions in the business and running of its operations enable improvement of the anticipated outcomes. Organizations have to establish Continue reading

What is Hyperledger Technology?
Hyperledger Fabric is an implementation from blockchain framework, hosted by the Linux Foundation. It is an open source enterprise-grade permission that makes use of distributed ledger technology. It is a platform that deploys blockchain networks with the platform providing smart contracts, the ledger, and providing a consensus between the members through maintenance of the Fabric protocols. Fabric is designed for use by businesses with the blockchain itself being operated by a set of known participants. These participants are re-identified and vetted through a concept called the permission blockchain. The blockchain also provides a way of securing an interaction among a group of entities who know each other and have common business interests. These entities are interested in managing a decentralized network instead of turning the management of their ledgers to one party. Through reliance on the identities and peers, the blockchain can use the traditional crash fault tolerant or the Continue reading
Database Security Threats and Countermeasures
Information is very critical asset. Organizations create so much information and they use database systems to handle the information within them to automate various functions. Due to information importance, information protection is a critical component of the database management system. Information security is the goal of a database management system (DBMS), also called database security. To be able to manage a huge amount of data effectively and fast, a well organized system is needed to build. It will also need to store and retrieve data easily. Generally, a database system is designed to be used by many users simultaneously for the specific collections of data. Databases are classified based on their types of collections, such as images, numeric, bibliographic or full-text. Digitized databases are created by using management system to make, store, maintain or search the data. Oracle, MS SQL and Sybase servers are mostly used in companies, agencies and Continue reading
Different Security Attacks on RFID Systems
Like other information systems, RFID systems are vulnerable to attack and can be compromised at various stages. Generally the attacks against a RFID system can be categorized into four major groups: attacks on authenticity, attacks on integrity, attacks on confidentiality, and attacks on availability. Besides being vulnerable to common attacks such as eavesdropping, man-in-the-middle and denial of service, RFID technology is, in particular, susceptible to spoof and power attacks. This section illustrates the different kinds of attacks on RFID systems. Eavesdropping: Since an RFID tag is a wireless device that emits a unique identifier upon interrogation by a RFID reader, there exists a risk that the communication between tag and reader can be eavesdropped. Eavesdropping occurs when an attacker intercepts data with any compliant reader for the correct tag family and frequency while a tag is being read by an authorized RFID reader. Since most RFID systems use clear text Continue reading
Role and Impact of Management Information Systems (MIS) in an Organization
Management information system (MIS) provides information that organizations require to manage themselves efficiently and effectively. Management information systems are typically computer systems used for managing the organizations. Management information systems are distinct from other information systems because they are used to analyze and facilitate strategic and operational activities. Role of Management Information Systems in an Organization The role of the MIS in an organization can be compared to the role of heart in the body. The information is the blood and MIS is the heart. In the body the heart plays the role of supplying pure blood to all the elements of the body including the brain. The heart works faster and supplies more blood when needed. It regulates and controls the incoming impure blood, processes it and sends it to the destination in the quantity needed. It fulfills the needs of blood supply to human body in normal course Continue reading
Cloud Computing Service Models
In practice, cloud service providers tend to offer services (ie. Cloud Computing Service Models) that can be grouped into three categories: software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (Iaas). 1. Software as a service (SaaS) Software as a service (SaaS) is software that is developed and hosted by the SaaS vendor and which the end user accesses over the Internet. Unlike traditional applications that users install on their computers or servers, SaaS software is owned by the vendor and runs on computers in the vendor’s data center (or a collocation facility). A single instance of the software runs on the cloud and services multiple end users or client organizations. Broadly speaking, all customers of a SaaS vendor use the same software: these are one-size-fits-all solutions. Well known examples are Salesforce.com, Google’s Gmail and Apps, instant messaging from AOL, Yahoo and Google, and Continue reading
