Abstract—Because of the drawbacks of the text based authentication systems, graphical passwords are the most preferable type of authentication mechanism , where users click on images for the authentication purpose. The main goal of an authentication system is to help users for selecting the better password. If the password is created by the user , then it is easy to guess by an attacker and if the passwords is assigned by the system, then it is difficult for the user to memorize. So modern researches
Kerberos was conceived as a secure network authentication technology at Massachusetts Institute of Technology (MIT), where it continues to evolve. Using encryption as a seal, Kerberos credentials, or tickets, vouch for authenticated users. Because every node on the network exclusively trusts the Kerberos server, users' credentials are valid throughout the network. This way, they theoretically have to log in only once. In addition, Kerberos can provide support for real-time encryption of network communications

describes the important aspects of network security. A secure network is one which is free of unauthorized entries and hackers INTRODUCTION Over the past few years, Internet-enabled business, or e-business, has drastically improved efficiency and revenue growth. E-business applications such as e-commerce, supply-chain management, and remote access allow companies to streamline processes, lower operating costs, and increase customer satisfaction. Such applications require mission-critical networks
character is entered, what is the expected time to discover the correct password? 3.5 A phonetic password generator picks two segments randomly for each six-letter password. The form of each segment is CVC (consonant, vowel, consonant), where V = 6 a, e, i, o, u 7 and C = V - . a. What is the total password population? b. What is the probability of an adversary guessing a password correctly? 3.6 Assume that passwords are limited to the use of the 95 printable ASCII characters and that all passwords
secure communications is that of cryptography. But it is important to note that while cryptography is necessary for secure communications, it is not by itself sufficient. There are some specific security requirements for cryptography, including Authentication, Privacy/confidentiality, and Integrity Non-repudiation. The three types of algorithms are described: (i) Secret Key Cryptography (SKC): Uses a single key for both encryption and decryption. (ii)Public Key Cryptography (PKC): Uses one key for

Authentication Authentication – the use of a system to allow user’s access to a computer or network based on three factors: something you know, something you have and something you are. Purpose: Authentication is the process of determining whether someone or something is, in fact, who or what it is declared to be. This will allow you to only allow certain

Rather than pursuing e-government as an end in itself, the Netherlands is seeking to use ICT tools to reduce administrative burdens and improve service delivery. Internationally, the Netherlands is at the forefront of administrative burden reduction, which is a major political priority and an important justification for e-government development. Today, from the wide application

1 Introduction In today’s security-conscious society, a reliable, robust and convenient approach for automated user authentication is becoming a strong requirement. Since September 2001 (i.e. World Trade Center blast), public awareness about the need for security has been increased considerably and lead to a massive rise in demand for the personal authentication systems (Wang et al., 2005). Biometrics plays a major role in today’s security applications. A biometric system is essentially
Introduction The development of technology has brought Internet to become the mass communication media between people or companies. Through Internet, people can communicate with other people in various places. Companies can get many advantages by using Internet network to support their business. Therefore, companies are trying as hard as they can, and give high effort in protecting their network from attack and make sure that they have the best network security. Most people think that the threat
ensure the protection of information which is transmitted over the Internet include: 1. The authentication of users. 2. The economical provision of single-user login services. 3. The provision of one security scheme which works both from within the user’s firewall and from outside that firewall. 4. The protection of the privacy and integrity of both real-time and store-and-forward applications such as e-mail. (Computer Reseller News PG). Part C -- Analysis of Impact of Issue The impacts
Operating System Architecture By gaining control of computers, computer viruses, worms, trojans, software bugs, and bad people can create extraordinary damage by shutting down infrastructure, using online banking to steal money, or using robots to attack people. Our civilization is increasingly depended on computers for survival. Therefore, a fully secure operating system is essential for the society. Below is the architecture by which maximum security against viruses and other threats can be
what Islam stands for in regard to women within their beliefs. The teachings of Islam are based essentially on the Qur'an (God's revelation) and Hadeeth (elaboration by Prophet Muhammad). The Qur'an and the Hadeeth provide the basic source of authentication for any position or view which is attributed to Islam. This report focuses on the position of Islam regarding the status of woman in society 3 METHODOLOGY The information of this report was obtained through: Mullah, Hassan Ismahael-
Computer security is the protection of the physical components of a computer and the software and data that is stored on computers. This security protects computers from theft, physical damage, data theft or loss, software damage, cloud threats, and network threats. There are different types of security measures for the varying components of computers. The components that need to be protected are hardware, software, network, cloud, and data. The security of computer hardware is important because
TJX breach overview TJX, the largest off‐price clothing retailer in the United States. Winners and HomeSense in Canada are two from the eight organizations. TJX faced the largest online hack with about 94 million records lost in 2006. The company found in December 2006 about the breach. After the investigation, the company found that they were losing sensitive information since 2005. Many small gift card transactions are recorded in the US. One Walmart employee had doubt on it because of the huge
Abstract - The main objective of Steganography is to communicate securely in such a way that the true message is not visible to the observer. Depending on the type of the cover object there are many suitable steganographic techniques which are followed in order to obtain security. The seganographic techniques can be classified as audio, video, text, image and network steganography. In this paper we have analyzed various data hiding techniques in encrypted images.

Database Security: Database security is a critical Domain of Computer and Information Security that deals with protection of an individual database or group of database from illegal access, injections or possible destruction. Data can be a customer's information, intellectual property, financial asset or any number of other records that can be maintained and managed on a system. Without Database security people are at risk of identity fraud, theft, destruction of property and much worse. The global
