The Importance of Physical Security

Authorization is the act of checking to determine if a user has the proper permission to access a file or perform an action, after the user has properly identified themselves through authentication (Username/Password). Authorization is provided to users based on a job requirement or a need to know that allows them to access the required material. Authorization is usually determined when a user first gains access to a system but may change over time. If a change occurs that requires more or less authorization for a particular employee, the concerned supervisor should contact the appropriate authority to make the change.

(TCO 6) Many believe that the most important physical security control is _____. (Points : 5)

Formal user access control procedures must be documented, implemented and kept up to date for each application and information system to ensure authorised user access and to prevent unauthorised access. They must cover all stages of the lifecycle of user access, from the initial registration of new users to the final de-registration of users who no longer require access. These must be agreed by IDI. User access rights must be reviewed at regular intervals to ensure that the appropriate rights are still allocated. System administration accounts must only be provided to users that are required to perform system administration tasks.

Access control refers to the mechanisms that identify who can and cannot access a network, resource, application, specific action.

Mandatory access control is a single user, normally the network admin, who is given access to the users’ rights and privileges. They control access policies and are also in control of choosing which objects and what systems each individual user has access to and what they do not have access to. The access is made in the form of different levels. Each system and all folders containing information are put into a specific classification. The user will be in a certain classification that will only allow them to access data

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

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.

As the use of computers, databases, and technology in general, security has grown to be a powerful tool that has to be used. The threat of outside sources intruding and exploiting crucial information is a threat that is present on a daily basis. As a part of creating and implementing a security policy, a user must consider access control. Access Control is a security tool that is used to control who can use or gain access to the protected technology. Access control security includes two levels; logical and physical. Though database intrusions can happen at any moment, access control provides another security barrier that is needed.

Confidentiality: Access controls help ensure that only authorized subjects can access objects. When unauthorized entities are able to access systems or data, it results in a loss of confidentiality.

Security is a central concern in the study of international relations (IR). Yet despite being the focus of considerable scrutiny, few agreed conceptions of security exist (Buzan, 1991; Huysmans, 2006; Terriff et al., 1991; McSweeney, 1999; Morgan, 1992; Croft 2012; Smith 2000). Buzan even goes as far to posit that the very conception of security is “essentially contested” and thus poses an unsolvable debate (Buzan, People, states and fear; Little, ideology and change, p35). These disagreements have created rifts in the security community over what can be threatened and indeed what can even be considered a threat. Part of the complexity to the subject is derived from the numerous opposing and often contradicting theoretical perspectives within international relations itself, of which security is a sub-field (Terrif et al. 1991 – Security studies today). This paper thereby seeks to trace the various theoretical strands of security studies with the hope of elucidating how and why Islam, and Muslims immigrants have been increasingly portrayed as a threat and ‘Otherised’ in Britain.
