Annotated Bibliography On The Security Of The Age Of Internet Essay

Cyber security threats change quickly as Internet increases, and also the related dangers are getting to be progressively international. Being covered against cyber security threats requires almost all end users, actually the most complex versions, to know the particular threats in addition to enhance their particular safety measures with a continuing foundation. On April 28, 2014 President Obama has declared that the “cyber threat is one of the most serious economic and national security challenges we face as a nation” and that “America 's economic prosperity in the 21st century will depend on cyber security.” The internet enables and also helps people in a many ways and a example is collect, store, process huge amounts of data, which includes vulnerable data of small business, transactional and personal. Everything in this world is based on internet now a days.

In this modern day and age of computing, networks are a huge part of IT. It is important now more than ever that data sent over any network, whether it be a LAN (Local Area Network) or WAN (Wide Area Network; The Internet) is kept safe, private (when required) and uninterrupted in

M2 – Explain the operation and use of encryption technique in ensuring security of transmitted information

I am Professor Kirk Mooring and I will be your instructor for this class. In this class, you will learn the fundamental core theories of information and network security. In this course, you will learn and use technology skills that are in demand in today’s job market. With so many threats and vulnerabilities created daily that we have to learn to work as a team in order to protect our data with the appropriate security safeguards. You will study the concepts that will help you evaluate and mitigate risk by selecting the appropriate security controls and technologies.

During this time Richard has showed himself as a promising young specialist and researcher. His major specialization is Applied Mathematics and Computer Science, but as an exception for academic achievements, Alex was allowed by our faculty to write his projects and degree thesis in the field of Cryptography under Computer Security and Applied Algebra Department.

            In the past decade, rapid advances have been made in the field of cryptography.  These advances have brought considerable

Many users are subject of Security and Privacy on the Internet issue. The term "information" now is more used when defining a special product or article of trade which could be bought, sold, exchanged, etc. Often the price of information is higher many times than the cost of the very computers and technologies where it is functioning. Naturally it raises the need of protecting information from unauthorized access, theft, destruction, and other crimes. However, many users do not realize that they risk their security and privacy online.

Information security is a major concept in today’s industrial and computer era, so security must be higher to protect the confidential data. Information security plays major role in computer and network security with the use of different cryptography algorithms that includes the encryption and decryption of data with the uses of the algorithm and the key. By means of text or numerical key for the encryption can be dangerous because with the several hack attacks that a key can be broken. So I have proposed a new mechanism that will replace the text key with the image pixels and can gain high security which cannot be easy to break without prior knowledge.

Data encryption and decryption have become increasingly important as more people are communicating over the internet. Although cryptology is not new, the demand for this technology has soared as its usefulness for security purposes has become more evident. Cryptology involves converting original messages into non-readable formats and plays an important role in keeping data safe while it is in transit (Agrawal & Mishra, 2012). Two popular forms of cryptology are symmetric and asymmetric.

The goal of our research paper is to provide a concise analysis on data security and privacy protection issues pertaining to data and databases as well as the current advancement/ breakthrough made and achieved in regards to database security and privacy concerns. We will also discuss in this paper some current solutions in the security market. First, we looked at the a trusted database model which makes it possible to shield database with absolute secrecy to benefit trusted equipment presented on the side of server and made to work at the charge of any cryptography which permits private data handling on a simple device.

The privacy preserving techniques also have data sanitization, cryptography techniques and access control techniques. The data sanitization techniques refer as a process, which conceals sensitive information in their data sets. Here in this method implements various techniques to offer the privacy to their dataset. The access control methods are implemented to reduce and handle the access to the host system and their applications through communication links. The cryptography techniques are implemented to offer a tough security and privacy and also offer exact and practical implementation. The cryptography protocols permits secure communications through addressing their authentication [1].

Safety of information is the most valuable asset in any organization particular those who provide financial service to others. Threats can come from a variety of sources such as human threats, natural disasters and technical threats. By identifying the potential threats to the network, security measure can be taken to combat these threats, eliminate them or reduce the likelihood and impact if they should occur.

The large and growing number of internet and wireless communication users has led to an increasing demand of security measures and devices for protecting the user data transmitted over the unsecured network so that unauthorized persons cannot access it. The increasing need for Secured data communication has led to development of several cryptography algorithms [31]. Cryptography uses the encryption algorithm and a key to send confidential data through an insecure channel[26] There are mainly two types of encryption algorithms, private key (also called symmetric key) and public key. Private key algorithms involve only one key, both for encryption and decryption whereas, public key algorithms involve two keys, one for encryption and other for decryption [29]. The public key algorithm is complex and has very high computation time. Private key algorithm is simple and therefore, it is more suitable for faster implementation [30].

Use of wireless network has tremendously increased and deployed both in the public environments and office, besides the Internet users at home. Apart from this wireless networking medium comes up with many advantages like productivity enhances because of the increased availability to resources. Configuring and reconfiguring of the network has become very easy. The users want this communication medium to be secure and free from attackers. Despite wireless networking comes up with many countermeasures against attacks, besides this it also has also new threats and modifies the authorized information security risk profile. For example, lets us consider a scenario where message or data is been transmitted between two parties

As known today, Cryptography is the transformation of message under the control of secret key and keeping
