...Network Access Control, no matter what architecture you select, you definitely want to start by building a small interoperability lab. In this white paper, we’ll give you some advice on what to think about before you get started, and outline what resources you’ll need to have in place in order to begin testing. Any NAC deployment must start by answering three critical questions: 1) What is my access control policy? 2) What are the access methods (such as LAN, wireless, or VPN) I want to protect? 3) How will this integrate with my existing infrastructure? Once you answer these questions, you can begin to gather test lab resources, such as servers (for policy definition points), laptops or desktops (for network access requestors), and switches, access points, and VPN servers (for policy enforcement points). Getting Started with Network Access Control What is my access control policy? NAC is a generic concept that deals with defining access controls based on user authentication, end-point security assessment, and network environmental information. That’s too big for most network managers to bite off in a single chunk, so many NAC deployments hone in on a subset of these goals and expand over time. You’d be wise to do the same---trying to do too much too early in the lifecycle of this emerging group of products will lead to undue frustration and unnecessary complexity. To start, you should define a simple network access control policy. It is important to define your access control...

...In computer security, access control includes authentication, authorization and accountability. In access control models, the human users or software which execute actions are defined as subjects; while the resources or whatever which are intended to be protected from illegal access are designated objects. Authentication is the process of verifying the credential provider claiming who he or she is. Before a subject open an account in online retailers or financial service firms, there is an initial step knew as identity proofing. That is, the subject must provide enough information to assert who you are. Right now there are three kinds of identity proofing , from simple to complex but with security assurance ascending. They are showed as follow: 1. Classic knowledge-based authentication (KBA), such as simple questions of “what is your favorite fruit”, which is easy to guess and the same to fraud. 2. Dynamic KBA. Instead of raise up questions predefined by the subject, the system generates questions on the fly based on the information in a subject’s personal aggregated data file from public records. To initiate the dynamic KBA, basic identification factors, such as name, address and date of birth must be provided by the subject. 3. Out-of-band proofing, which verify identity through other means such as SMS or a phone call rather than web channel. The credential used to identify the subject includes: 1. Something the subject knows, such as Personal Information Number (PIN) ...

...In scenario one, I would think that one of the most important would be software controls so that you know what your employees of such a small business are doing. You would want to make sure that they are being productive and not taking out any of your customers’ sensitive information. Most likely you would store your vendor’s information, purchase orders, and customer’s information. This might include account numbers, or contact information that you wouldn’t want just anyone to get a hold of. Therefore you wouldn’t want to allow anyone to cause you to lose this information by causing your network to get a virus. Even more simpler than that would be due to the fact you are as small as you are, you most likely don’t have a administrator present all the time, and would have to contract out someone to come fix the network if some sort of attack was caused by loading unapproved software onto the system. In scenario two, I believe that you would have similar needs of above, but also would want to have some more in depth administrative controls on the smartphone side of business. You wouldn’t want someone to have something unprofessional on the voice mail of the phone, or even downloading applications that would allow the company to lose money in wages from employees not utilizing the resources that are given properly. In scenario three, you would want emphasize on the physical end of the security. I believe this because with 120,000 computers and 45,000 servers, you have...

... Access Control Policy Student Name: Christopher Waller University of Phoenix IT/244 Intro to IT Security Instructor’s Name: Romel Llarena Date: May 13, 2012 Access Control Policy Due in Week Seven: Outline the Access Control Policy. Describe how access control methodologies work to secure information systems 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 really help control access to sensitive data or systems by making it literally to get unauthorized access to them. Passwords and usernames are a good way to start because if you use those rights then these are hard to bypass, but multifactor authentication is a more efficient way for secure access. Triple authentication requires something you have, something you know, and something you are such as a keycard, password and a fingerprint. 2 Access control strategy 1 Discretionary access control Describe how and why discretionary access control will be used. Include an explanation of how the principle of least privilege applies to assure confidentiality. Explain who the information owner is that has the responsibility for the information and has the discretion to dictate access to that information...

...Abstract Access control systems were examined to determine if a network based system would be more reliable and beneficial. Two major systems were determined to be very beneficial to the company. In contrast, the systems would consume a great deal of resources in order to be put into full working order at all sites worldwide. Together these findings suggest that using a network based system can ultimately serve the company better and create a more secure environment for the research and the employees. Keywords: Access control, CCURE, Locknetics, security, networking Network Based Access Control Systems: What Are They? Personal and confidential information can easily be accessed at sites if the access to the specific areas is not updated quickly enough. To secure and protect this data, technology must adapt to mitigate the threats and risks. Applications and services are becoming mobile across multiple resources, sometimes in a dynamically allocated way, necessitating the migration of sensitive and private data. I propose a network based access control system to address the inadequacies of current technological solutions in preserving the confidentiality and privacy of data, along with the safety and security of the site. More specifically, I describe a solution for securing all Bristol-Myers Squibb sites throughout the world. Access control systems have become a basic way of life for many businesses, especially large businesses. There are many different variations...

...ACCESS CONTROL MODELS An access control model is a framework that dictates how subjects access objects. There are three main types of access control model mandatory access control, discretionary access control and role-based access control. Discretionary (DAC) The creator of a file is the ‘owner’ and can grant ownership to others. Access control is at the discretion of the owner. Most common implementation is through access control lists. Discretionary access control is required for the Orange Book “C” Level. Mandatory (MAC) Much more structured. Is based on security labels and classifications. Access decisions are based on clearance level of the data and clearance level of the user, and, classification of the object. Rules are made by management, configured by the administrators and enforced by the operating system. Mandatory access control is required for the Orange Book “B” Level. Role-Based (RBAC) Continually administered set of controls by role within organization. Access rights assigned to roles – not directly to users. Roles are tighter controlled than groups - a user can only have one role. Can use different types of RBAC Role-based Role within organization. Task-based Specific task assigned to the user. Lattice-based Upper and Lower bounds Access Control Techniques and Technologies Once a company decides on the access control model to use, the technologies and techniques to implement that model need to be determined Role-based Can be used with...

...BIOMETRIC ACCESS CONTROL Access control is the method used to control access to your Computer System, and the method used to control access to files held on your computer system. For the moment we are just going to look at controlling access to the computer itself rather than individual files. Traditional access control is software based and follows a standard procedure of identification and authentication. Users must first declare who they are, and then attempt to prove who they are who they say they are. This is generally part of a long on procedure that involves a user name and password.

Describe how access control methodologies work to secure information systems Access control is used to 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.
