Your assignment is to prepare and submit a paper on the history of information security. The traditional information security techniques that were used in ancient Egypt such as data hiding, watermarking, and cryptography, are some of the basic notions, and they do play a significant role in the development of the information security sector algorithms and solutions. A new trend in information security includes biometric technologies that deliver good security levels nowadays. It is easy to combine the traditional techniques with biometrics so as to realize much resilient security levels. The field of technology in line with information security has continued to develop in leaps since ancient times (Blackwood 396). Despite the fact that not all companies or organizations have been in a position to embrace the latest security systems, information security will surely grow to a greater height.

Information security is a concept that is broad than technology. It involves protecting information and relevant information systems from access that is not authorized or use, disclose, disrupt, and destroy vital information. There has never been some struggle or effort to come up with an all-inclusive history regarding information security (Blackwood 97). This is quite unfortunate simply because information security should be taken as a set of vessels that are communicating, where the technical inventions can make the prevailing organizational frame-works obsolescent, and a failure of political authority may lead to a special dependence on the technical means. The aim of this paper is to critically analyze the history of information security from Ancient Egypt to the present day.

Egypt is one of the most talked-about civilizations in the world. Ranging from its quest for development in agriculture, trade, and industry, the country had also a great interest in technological development especially in information security. The development of the forms of information security in Egypt has been stepwise. One main form that was used is encryption. This is the process of converting messages or data into a form that is not readable to any person except apart from&nbsp.the intended recipient of the information.

Write a 6 pages paper on managed pressure and underbalanced drilling. The economic revolution of the modern era is exclusively based on the availability of quality oil and gas products. Therefore, scientists have been working on various methods to improve the extraction procedures for fuel. Underbalanced drilling and managed pressure drilling are two of the most common drilling techniques being implemented in today’s oil and gas industry. Underbalanced drilling is opposite to conventional drilling techniques. In this technique wellbore pressure is kept lower as compared to formation fluid, this result in the smooth movement of formation fluids to the surface of the wellbore(Gala and Toralde, 2011) and helps to avoid blowouts.

Underbalanced drilling is good to be used in drilling rigs as it provides the least wear to the well with increased production rate(NW_Air, 2014), but meanwhile, this technique is expensive and unreliable. While drilling deeper in the wellbore, it is sometimes difficult to maintain an underbalanced condition and the pressure within the wellbore is increased may be as a result of increased density of soil. The boring will ultimately be shifted to an overbalanced condition and this may harm the system resulting in irreversible damage and making the oil extraction expensive. Another most common drilling technique is the modification of an overbalanced technique and is used where wellbore pressure is kept higher but is continuously monitored and maintained in order to avoid any unpleasant situation. If the wellbore pressure becomes excessively high, then it is maintained by making use of different densities of mud and formation fluids and also controlling by not generating continuous influx formation fluid to the surface of the wellbore. This method is exclusively known as managed pressure drilling as it makes use of an adaptive technique to control the balance between the wellbore and its environment(Montilva et al., 2010).
