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
objective is to access the security portal remotely with biometric authentication. 1.3 PROBLEM SPECIFICATION: To have security for the credential it is necessary to have a secure communication link for remote accessing the portal. The storage used for the unique authentication information generated form the biometric sensors should be kept with high
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
keep out cyber criminals. Vulnerability is a weakness in a security system. A threat is a set of circumstances that has the potential to cause loss or harm. How do we address the problems of threats and vulnerabilities? We use control as a defensive method. Control is an action, device, procedure, or technique that removes or reduces vulnerability. (Pfleeger & Pfleeger, 2007)It is essential to have adequately qualified IT personnel on the security team to properly monitor the network’s activity log
the Access Control Policy. Describe how access control methodologies work to secure information systems 1.1. Authentication Describe how and why authentication credentials are used to identify and control access to files, screens, and systems. Include a discussion of the principles of authentication such as passwords, multifactor authentication, biometrics, and single-sign-on. Authentication credentials are vital to the security of information within an organization. The first thing that needs to be
because of it's vulnerability. Threat to computing security takes place by a person, event or circumstance may be intentionally for sake of finance or unintentionally by deleting some of the important data. A threat agent depends on method, opportunity and motivation. Method is a knowledge to attack , oppurtinity to access the necessary information and motive behind the aatack. In olden days during 1980's and 1990's it is done for the sake of personal fame, but in 2000's it is for financial purpose
installing the new system and retiring the old system. The four methods in the installation process are direct cutover, parallel operation, pilot operation, and phased changeover (Wikipedia, 2006). In direct cutover they old system is instantly change from old to new. Parallel operation requires that both system run for a certain time period before the old system is turned off. Pilot operation and phased changeover fall in between the other two methods. All installation process have there benefits and disadvantages

Abstract--- Biometrics covers a variety of technologies in which unique identifiable attributes of people are used for identification and authentication. Palm print recognition system is widespread bio-metric authentication systems. A palm print is the feature pattern on the basis of their edges. Each person has his own palm prints with the permanent uniqueness. The common problem for palm print recognition is finding the minutiae by its local features and edges. Rotation and location invariant
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 encryption and another for decryption. (iii)Hash Functions: Uses mathematical transformation to irreversibly "encrypt" information. Steganography is the other technique for secured communication. It encompasses methods of transmitting

Fuzzy Optimization & Decision Making, 7(3), 243-256. doi: 10.1007/s10700-008-9034-1 This article examines the use of multiple authentication methods to increase the security of a system. Moreover, with the use of biometric methods, the author seeks to show that authentication can occur continually during the time the resources are being utilized. Within the article the authors point out the use of biometric and multi-modal authentication techniques, pointing
Biometrics The term biometrics is commonly known as the field of development of statistical and mathematical methods applicable to data analysis problems in the biological sciences. Though, even more recently it has taken on a whole new definition. Biometrics is an amazing new topic referring to “the emerging field of technology devoted to the identification of individuals using biological traits, based on retinal or iris scanning, fingerprints, or face recognition”. Biometrics has already
TNC is basically used for NAC (Authentication Purpose). The Architecture of NAC provides a clear background of how a network can be made secure and how to avoid unauthorized access. IEEE 802.1x is a standard which provide port based network access control and protect the network from unauthorized access. If the access register is unauthorized then access is given but access is not given when the access is unauthorized. IEEE 802.1x is basically used for authentication and authorization purpose. This
Detecting Wireless LAN MAC Address Spoofing Abstract An attacker wishing to disrupt a wireless network has a wide arsenal available to them. Many of these tools rely on using a faked MAC address, masquerading as an authorized wireless access point or as an authorized client. Using these tools, an attacker can launch denial of service attacks, bypass access control mechanisms, or falsely advertise services to wireless clients. This presents unique opportunities for attacks against wireless
Hailey Laferty Mr. Christian Computer Applications II 8 April 2015 Computer Security How can your password be stolen? And how do you stop someone from stealing your password? Are there levels of computer security? And if there are what are they? All of these questions will be answered and maybe even more. How can your password be stolen? There are many ways your password can be stolen. For example, you might be putting in your password and someone looks over your shoulder. But that is only one
The WPS protocol relies on an eight digit Personal Identification Number (PIN) to allow the authentication of users on to the network. The protocol further relies on a session of eight Extensible Authentication Protocol (EAP) messages that are followed by a final message which identifies the successful completion of the session. WPS automatically configures the network name (SSID) and the WPA security key for the access point and the WPS enabled client. The benefit is that a user does not need to
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
merging in regular use being deployed in various applications such immigration border control, forensic systems and payment authentication. The use of biometrics for people identification is considered as a vital tool during forensic investigation. Forensic science can be defined as the method of gathering, analysing and interpreting past information related to criminal, civil or administrative law. This includes the perpetrator identity and the modus operandi [30]. Forensics involves several processes
developed security systems that can actually authenticate a person. This report will be looking at these advancements as well as my thoughts of them. The improvement in security was developed on the bases of biometrics. Biometrics refers to the authentication techniques that rely on measurable characteristics that can be automatically checked. [1] Biometric techniques are divided into physiological and behavioral characteristics. Physiological characteristics include: the finger, palm, the face, and
levels and these are termed the Handshake Protocol and the Record Protocol. The Handshake protocol means that the client and server are able to correspond with one another though only if authentication has been established. Both the client and server can then come to a decision on a particular encryption method before any data can be transmitt... ... middle of paper ... ...014]. McKinley, H. L., 2003.
