Identification and Authentication: ID and validation are the most essential in the matter of security. Without both of these then your framework is powerless. The organization need to have somehow of knowing who is in the framework and what they are doing. If you have no possibility to get to knowing then how would you know whether somebody that is not assume to be survey an index is not taking a gander at the document? The response is that you don't have the foggiest idea. At whatever point
security issue have become a top priority in every organization that makes use of information. Securing digital identities is getting more and more crucial. For authentication the usage of passwords is no longer sufficient because it faces most modern means of attacks and thus stronger authentication schemes are needed. Strong authentication solutions having two identification factors require often an additional device, which could be difficult for the user and costly for the service providers. In
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
1.2 Sender Authentication Speech is probably the most efficient way to communicate with each other. This also means that speech could be a useful interface to interact with machines Thus speech is one of the main features used by humans for person authentication. The other reason for the selection of these biometric are as follows- • The ease of collection of biometric data. • The sensors cost is very less. • Set up for data collection will not need any special arrangement. A Speech
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
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
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
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
and back up the hierarchy. Since the process begins at the seventh level, the Application level, it will be detailed first. As its name implies, this Application level supports applications, but it also supports other end-user processes. User authentication and privacy on the network is consid...
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. In our situation with the old authentication system and the new authentication each department was able to run a parallel operation.
home, a AAA radius server is not deployed in the infrastructure. The secret key in this case is usually stored on an access point. In such environment setup, the authentication takes place between the station and the access point. To secure the network setup, WPA2 can be used along with the optional Pre-Shared Key (PSK) for authentication. To encrypt the network with WPA2-PSK, the router is configured not with an encryption key but rather plain paraphrase. TKIP(for Temporal Key Integrity Protocol)
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
browser Single Sign On (SSO), and defined by OASIS. It is in rife since 2002. SAML is called a security markup language because this is specifically defined to exchange security and identity related information such as authorization information and authentication information etc. Background Its first version came in 2002 as SAML 1.0 and the latest version released in 2005 as SAML 2.0. Another version came in between as SAML 1.1. Why SAML! In view of emergence in cloud computing and cloud based identity
database itself. A couple of measures can be implemented such as use of firewall to secure the web servers as well as the databases. The information sent and accessed over the distributed systems or network can be made secure by number of ways; authentication certificates, use of secure sockets and primarily help to prevent the attack from collecting information through network sniffing.
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
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
Identify Security Measures Which Address These Threats and Vulnerabilities Any network is vulnerable at its weakest point and perpetrators will try to get in any way that they can. Some just to see if they can and others for manipulated personal gain. Security measures, policy and procedures are written and tailored to meet the specific needs of an organization. Security tools are installed on networks to keep out cyber criminals. Vulnerability is a weakness in a security system. A threat is
Proposal Dustin Riedemann Kaplan University IT286: Introduction to Network Security Prof: Denver Lee Martin September 30, 2013 I. 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

Computer security is very essential to proyect against the threats caused to computing system which happen 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
