From a security standpoint, this access control method has the most potential as it is difficult to replicate a finger print, or retinal scan.
4) The forth factor is someone you know. In this access control concept, another person who knows the individual in question can provide a human element of authentication in situations where systems have been set up to allow for such scenarios. For example, a user may have their password, but have forgotten their smart card. In such a scenario, if the user is known to designated cohorts, the cohorts may provide their smart card and password, in combination with the extant factor of the user in question, and thus provide two factors for the user with the missing credential, giving three factors overall to allow access (Rhee, 2003) Discretionary Access Control (DAC)
In addition to the factors mentioned above, access can be granted based on specific metrics or criteria. These criteria are particularly useful online, as it allows individuals to limit their overall exposure to a data breach. There are four main methods in which to do so (Gralla, 2007).
1. Mandatory Access Control (MAC)
In MAC, users do not have much freedom to determine who has access to their files. Instead certain categories of clearance of given to certain individuals based on factors such as trust, tenure and knowledge. For example, security clearance for those individuals in the military. In these situations, depending on the level of clearance, certain information can be accessed.
In DAC, the data owner determines who can access specific resources. For example, a system administrator may create a hierarchy of files to be accessed based on certain permissions. This system is used primarily in companies that rely heavily on human capital. Google may only want to allow access to its search engine algorithm to certain individuals within the company.
3. Role-Based Access Control (RBAC)
RBAC allows access based on the job title. For example, a human resources specialist should not have permissions to create network accounts; this should be a role reserved for network administrators. This is often used throughout business to prevent fraud or criminal activity. By restricting access based on job title, certain individuals can only perform certain tasks. This helps to better pinpoint any discrepancies or questionable activity that may occur.
4. Rule-Based Access Control this form of access control is based a certain criteria or constraint. An example of this would be only allowing students to use the labs during a certain time of the day. This access control limits the available time that a breach can potentially occur (Gralla, 2007).

" (Tolone, Ahn, Pai, et al. 2005 P. 37). Table 1 provides the summary of the evaluation of various criteria mentioned in the paper. The table uses comparative terminology such as High, Medium and Low and, descriptive terminology such as Active, Passive, and Simple, and the standard Yes (Y) and No (N). The research provides the solutions based in the problems identified with the access controls evaluated. Table I: Evaluation of Access
Access to Healthcare: For the last two decades, access to healthcare is an issue that has played a crucial role in leading the charge for health care reforms. Access to quality and comprehensive health care services is a crucial aspect for the realization of health equity and for enhancing the quality of health for every individual. Generally, the access to these services means the timely use of individual health services in
A contact management system, or customer relationship management system, primarily makes use of a database containing profiles and contact information of potential and existing customers. This is very useful for marketing, sales, and customer service. It can help improve a business by targeting a marketing or sales effort to a specific group of people. For example, a company may offer to sell tennis equipment to people who already play tennis
Access to Healthcare According to the National Association of Community Health Centers (NACHC), 36 million Americans do not have access to basic health care. This number represents one in eight Americans (36 million Americans lack access to basic health care) who reside mostly in inner cities and in isolated rural communities. Half of these people are from low-income families and two in five are minorities. As many as twenty-eight percent of
5. There were 2,340 deaths attributed to IPV in 2007 (70% female; 30% male). Describe the relevance and application of this information to criminal justice professionals. Despite an increasing amount of research into intimate partner violence, no single theoretical approach has been offered that can explain it (Begun, 1999). The research to date indicates that there is an inextricable relationship between intimate partner violence and problems with stress, depression, or substance abuse
Further, in order to be covered by Medicare, the stay at the nursing home must include care that requires skilled nursing. In other words, Medicare will not cover custodial, non-skilled or long-term care that includes activities of daily living, such as cooking, cleaning and hygiene. A stay at a skilled nursing facility under Medicare is limited to one-hundred days per ailment. Medicare will pay for the first twenty days
