...Computers, networks, and software are the heart and soul of the IT world today. Because of the availability of those systems, they are very vulnerable to malicious attacks and activity. It is of upmost importance that an organization takes security seriously and takes the proper measures to protect their systems. They can do this through a number of different ways, but one area of focus is through the authentication process and the related hardware and software to go along with it. Identification and Authentication Authentication is the process of the system or program recognizing the user and granting them access, which has been predetermined by access controls. It begins with two major parts; Identification and Authentication. Identification is the process in which the system recognizes the user and gives them access according to Abstract object that are controlled by the administrators of the files and systems. Privileges will be granted based on their user account having been verified. This process is usually a user ID. The system recognized the ID and knows the access right and privileges of that individual that have been verified. The Authentication begins once the user account ID has been identified. This is the process in which the user credentials are actually verified, meaning the specific attributes of their specific user account and authenticated and verified to make sure the access rights are correct. This process uses a password or some sort of credential such...

...restrict operations, which authorized users can perform. Access control does exactly what it says, it controls what access an authorized user can have. A reference monitor is used for access control and follows instructions from an authorization database. These authorizations are controlled and administered by a security administrator who sets the access controls based on the companies’ security policies, which are defined by the organization. The decision of which access controls to use would be based on the organizational policy and two accepted standards of practice, which includes separation of duties and least privilege (Kurzban, 2011). 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. Today, when using a computer system, a number of computer services are provided to many users simultaneously, so it is important to ensure that authorized users will be granted access to the system. Usernames and passwords, or just passwords alone were created to authenticate who a person was and what access this person would be allowed (Apache.org, 2011). This would determine by the system what operations could be performed by the user. The system keeps a record of this authentication, which is used each time the user logs in. More modern...

...Microsoft Windows Operating System ONE OF THE MORE DIFFICULT TASKS when securing any computer system or network is identifying where to start. There are many components in any computing environment. Each component is a potential point of attack. Since the operating system provides the ability for software and hardware to interact it is a good starting point for securing an entire environment. On any computer, the operating system enables software to access physical resources. For example, it is the operating system that governs how any application actually reads from, or writes to, a physical disk. Consequently, the operating system is a prime candidate for attack and a valuable resource to protect. From an attacker's point of view, a compromised operating system provides easy access to protected information. Compromising operating system controls gives the attacker the ability to remove evidence of attacks and "clean up" any leftover log entries or other traces of the attack. A secure operating system is the basis of a secure environment. In this chapter you will learn about the Windows operating system architecture and controls to ensure system security. You will also learn how attackers search for, find, and exploit operating system vulnerabilities. With the knowledge of how attackers operate you'll be able to identify and implement the right controls to secure your environment. Chapter 2 Topics In this chapter, the following topics and concepts are presented: What the organ...

...the internet secure from risks and threats. Remote access enables users outside a network access and provides privileges based on the security settings. Users are able to access resources through an internet service provider or ISP which is connecting remotely to the resources online. Secure connectivity is able to be done due to an authentication process, this process establishes a user’s identification to enable access and grant permissions. There are several ways to establish a network connection based on the software, hardware, and network type and security requirements. Security authentication Wireless devices are able to connect remotely involving two elements: a temporary network connection and a series of protocols that set the privileges and commands. The temporary network connection, occurred through a wired connection or wireless access, or any other method of connecting to a network. The primary issue is authenticating the identity of the user and establishing proper privileges for that user. This is accomplished using a combination of protocols and the operating system on the host machine. The three steps in the establishment of proper privileges are authentication, authorization, and accounting, also known as AAA. Authentication is the matching of user-supplied credentials to previously stored credentials on a host machine, and it usually involves an account username and password. Once the user is authenticated, the authorization step takes place. Authorization...

...Information Authentication is a very common aspect of today's technology world. Anyone that uses a computer or mobile device has most likely used some form of it when logging into school accounts, shopping online, using social media, or accessing systems at work. What most individuals do not realize is that there are differing forms of authentication and ways it is used. Additionally, most people will not have any idea what is going on behind the scenes during authentication. He or she only knows that a login ID and password are required to gain access to the system. What is Authentication? The authentication process and other considerations affect the entire design and development for information systems. This and other preventative measures are used for securing data over a variety of systems. In order to learn about the authentication process, first it must be understood what security authentication is. The commonly accepted definition of security authentication is, according to “The business Of Authentication” (n.d.) “…the process of determining if a user or identity is who they claim to be. Authentication is accomplished using something the user knows (e.g. password), something the user has (e.g. security token) or something of the user (e.g. biometric) (para. 1). The important terms here are something the user has and something the user knows. In early authentication processes like automated teller machines (ATM), this idea was used by giving the user a card with...

...In the present mobile communication environment, lot of research is going on, to improve the performance of issues like handoffs, routing etc. Security is another key issue that needs to be considered, which comes into picture once the communication channel is setup. Many security protocols are being proposed for different applications like Wireless Application Protocol, 802.11 etc. most of them are based on the public and private key cryptography. This paper provides an insight on these cryptographic protocols and also looks into the current research project going on at Sun Microsystems Lab on wireless security. 1.Introduction With the rapid growth in the wireless mobile communication technology, small devices like PDAs, laptops are able to communicate with the fixed wired network while in motion. Because of its flexibility and provision of providing ubiquitous infrastructure, the need to provide security increases to a great degree. As wireless communication takes place mainly through the radio signals rather than wires, it is easier to intercept or eavesdrop on the communication channels. Therefore, it is important to provide security from all these threats. There are different kinds of issues within security like confidentiality, integrity, availability, legitimacy, and accountability that needs to be individually taken care off. One of the key issues of these being, confidentiality and authentication, where the user must be protected from unauthorized...

...Security Authentication Process CMGT/400 February 9, 2013 Anthony Seymour Security Authentication Process Like most people who are computer users, you do not simply turn on your computer and start accessing programs. There are systems put in place by the user, or the administrator of the network to ensure that the properly authorized people gain access to their information. Specific profiles are created to differentiate amongst the users that allow each unique user to create, delete, and print or any other process they have access to. The process needs to be thoroughly planned out, and there also has to be a determination how whether it will be managed locally, or by third party software. This management of access controls actually comes in four different steps. The steps are: Identification, Authentication, Authorization, and finally, Accountability. No administrator worth his salt will incorporate any sort of security authentication process without these four basic steps. A properly configure authentication process will protect your network from such threats as password cracking tools, brute force attacks, the abuse of system rights and outright impersonation of authenticated users. Identification is the first of the four steps of the security process. Anyone that wishes to gain access to a system is referred to as a supplicant, and the tool that they use to gain entry to the system is referred to as an Identifier. This identifier can be a myriad of different references...

...Enterprise Security Network Access Control: User and Device Authentication August 2005 Intel IT is piloting new security methods to provide network access control by authenticating devices as well as users. Since networking has evolved to support both wired and wireless access, securing corporate networks from attack has become ever more essential. Therefore, to effectively enforce network access control policies in a proactive manner, we are developing a method to authenticate users and devices before they connect to the network. Network Access Control at Intel • Over 90,000 employees worldwide • 80 percent of knowledge workers are mobile and unwired • Over 50,000 remote access users Background As a global corporation, Intel IT supports more than 90,000 employees and contractors all over the world, and 80 percent of our knowledge workers are mobile and unwired. Network access depends more and more upon wireless LANs and WANs, as well as virtual private network (VPN) remote access. All of these technologies have the potential to open our network perimeter to threats. When we considered the threat of viruses and worms, it was evident that we needed additional controls to secure the enterprise network and its information assets from unauthorized devices and unauthorized people. Figure 1 shows how we could authenticate devices and users as part of the authentication pyramid. Figure 1. Authentication pyramid Info Use Auditing Access Control User Device Authentification...
