A Brief Note On Access Control Access Controls

All passwords should be promptly changed if they are suspected of being disclosed, or are known to have

Confidentiality is the protection of information from unauthorized access. This is the assurance that information provided has not been made known to unauthorized persons, processes or devices. The application of this security service suggests information labeling and need-to-know imperatives are core aspects of the system security policy. Information, in today’s world, has value and everyone has information they wish to keep secret. Information such as credit card details, trade secrets, personal information, government documents, and many more. It was stated (Securitas Operandi™, 2008) that, we are bound to keep many secrets – corporate, staff, and personal secrets. We must keep this confidential information under wraps and earn the trust of employers, colleagues, and regulators every day. Mechanisms to enforce this include cryptography, which is, encrypting and decrypting data, access controls such as

Another example of a access control model that can be applied in this situation is known as the Clark and Wilson Integrity Model. This model provides improvements from the Biba Integrity Model of access control. Developed by David Clark and David Wilson, the mode concentrates on what happens when a user tries to do things they are not permitted to do, which was one flaw of the Biba Integrity Model . The other flaw that was addressed was the model also reviews internal integrity threats . There are 3 key elements of the Clark and Wilson integrity model; the first it stops unauthorized users from making changes within the system. The second, it stops authorized users from making improper changes, and the third, it maintains consistency both internally and externally . Within the Clark and Wilson model a user’s access is controlled by

Company must also develop a clear structure for granting employees access to sensitive information. Not all employees need such data in order to fulfill their everyday job responsibilities. For those who need admission to sensitive information, a strong authentication mechanism must be developed, which cannot be bypassed. This will ensure that only authorized users are accessing compromising data.

The framework of security policy is defined to construct a structure by the help of which policy gaps can be identified in an easy manner. A system specific policy would assist to ensure that all employees and management comply with the policies. This is also used to maintain the confidentiality for user authentication would assist in the confidentiality aspect of security, maintain integrity (There are several limiting rules or constraints which are distinct in the relational data model and whose work is to maintain the data’s accuracy and maintain its integrity.), availability and authenticity of the system. Access controls are a collection of mechanisms that work together to create security architecture to protect the assets of an information system. One of the goals of access control is personal accountability, which is the mechanism that proves someone performed a computer activity at a specific point in time. So, the framework acts as the guideline

Every organization must have adequate control mechanisms in place to help protect sensitive information from the distribution or transmission outside the organization, inappropriate disclosure, and control of how the information accessed is used. Companies should have policies in place that outline the course of action to take should inappropriate usage or disclosure of data be

This paper will discuss a better way to control user access to data is to tie data access to the role a user plays in an organization. It will cover the value of separating duties in the organization. Then discuss the value of using roles to segregate the data and system access needs of individuals in the organization. Then describe in detail why a role-based access control system (RBAC) would be the best way to accomplish this. Finally, how to handle distributed trust management issues for users going to or from business partner networks.

Role-based access controls meet the HIPAA Privacy Rule Minimum Necessary standard because it provides security access to individuals accessing a computer or its network by establishing access control requirements. Additionally, role-based access controls meet the minimum necessary standards because they focus on providing access to individuals based on their job role/job function within the facility. Moreover, according to (Amatayakul M. , 2008), the role-based access control, also control how covered entities (facilities) use the patient’s personal health information. Additionally, the role-based access controls also meet the HIPAA Privacy Rule Minimum Necessary standards because much like the Privacy Rule that focuses on setting limits on

For example a clerk will only be able to access a limited amount of information, such as inventory at each store. The limitations will be different for an accountant or the mangers. All information will be protected with several different layers of security. The first layers will be simple hardware protection for access to the network; from there the security will increase with password protection and restrictions to users. (Merkow & Breithaupt 2006)

The next step option to further prevent this security will involve restricting access to data by requiring a password, personal identification numbers, or a callback procedure. This approach will restrict logon time to a maximum of 2 minutes; if the computer goes idle for 2 minutes, a login password will be required to gain access to the system. The only problem with previous approach will the redundant need to frequently reenter password, to alleviate this problem associated with redundant authentication, the organization can adopt the use of a biometric method of authentication, for example, the use iris scanner, fingerprint, or an electronic signature (Joos et al, 2010).

Access control system is a system designed to control entry to prevent intruders into selected areas and manage movement of people/vehicles within. Its purpose is to increase security by determining who, when and where are they allowed to enter or exit.

Authentication and privilege attacks: Passwords remain the number one vulnerability in many systems. It is not an easy task to have a secure system whereby people are required to choose a unique password that others cannot guess but is still easy for them to remember. Nowadays most people have at least five other passwords to remember, and the password used for company business should not be the same one used for webmail accounts, site memberships and so on. Password policies can go a long way to mitigate the risk, but if the password policy is too strict people will find ways and means to get around it. They will write the password on sticky notes, share them with their colleagues or simply find a keyboard pattern (1q2w3e4r5t) that is easy to remember but also easy to guess.

Do you ever think about what is the reason for limiting people's access? There are reasons for and against laws which limit people’s access to information. Limiting people’s access could have some benefits and risks to.

Role based access control is an ideology through which access to systems is restricted based on authority given. It is used by organizations with a relatively large number of employees ranging from five hundred to one thousand and above (Sieunarine & University of Oxford, 2011). This is implemented through the mandatory access control or through the discretionary access control. These are the only two ways through which role based access control can be implemented.

Access control has been in use before the growth of the technology world. It could involve a simple action as locking a door. A person locks a door to prevent entry to those who are not allowed or authorize to do so. The same can be said about the security involving databases and the controlling of who can have access and what can be accessed. As far as database security is concerned, there are various categories that are involved in access control. The four main categories of access control include: Discretionary, Mandatory, Role-based, and Rule-based access control.
