Heterogeneous and dynamic environments creates a need for a viable access control system in such a way that the security of data and information will be solidly ensured. Organizations have various types of resources that need access regulation. The purpose of which is to make sure that only the intended can access the resources while keeping the unauthorized person out of the loop. Even at that, hierarchy, type and the degree of task delegated to a user will determine the level of access that he or she will be granted. For example, a user with role “accountant” normally has different access rights than user with role “supervisor”. The sensitivity of resources is directly proportional to the security level mounted upon the resources and likewise the degree of access.
Many challenges are witnessed during the course of implementing access control mechanism in information security, and all of them cannot be dealt with equally. This development introduced threat to information security which consequently sets in the requirement for appropriate countermeasures in ensuring risk of losing sensitive and important data into the hands of unauthorized users are mitigated. In this paper, the role played by the access control models in dictating the path in granting or denying specific access requests will be investigated in a dynamic information security environment.
Current researches studies many methodologies and appreciations for the evaluation and implementation of protection and controls with information privacy [4]. However, since access control application is a major factor in information system security, there is a need for building a dynamic access control policy. These policies form the certificatory, regulatory and, legislator requ...

... the audit data collection and organization, and analysis of the data to unravel security and access control policies violation (Lunt, 1993; Mukherjee, Heberlein & Levitt, 1994).
Consequently, audit data requires additional protection from modification by an attacker or intruder. But incidentally, analysis of audit data are in most case performed whenever a foul-play is suspected. Intrusion Detection System (IDS) is one of the key tools that seeks to help perform access control audit.
Today, access control audit is inevitable, mostly in IT industry. Seeing the recent database usage increase, growth of networks access points (most especially in remote connectivity), and rate at which wireless technologies evolve, it is absolutely essential to assess the efficiency of the available access control mechanism to verify the alignment of protection-level to the risk-level.
The analysis conducted by Control Data Corporation (1999), provides a quality, and precise assessment of adhering to cybersecurity policy. This analysis is organized into several different categories:
IT managers who did not have RADIUS have had to maintain access rights on multiple pieces of equipment. This leads to a problem: If someone joins or leaves a company, a manager must add or change access rights for that person on every piece of access equipment.
Security architecture is a major component and part of a system’s architecture and is usually designed to provide important guidance during the development of the system. It usually outlines the assurance level required and in the process outlines the possible impacts that this level of security might have on the development process of the actual system. Since security is a major component for the success of any given business unit, it is necessary to have a fully functional and operative security system that meets all the necessary requirements for any organization. Some leading business firms are usually faced with the task of achieving and maintaining high security measures and methods. SecureTek one of the leading provider of security solutions is faced with the challenge of redesigning their security architecture to assure security to the data and the other firm’s valuable assets as well as ensuring security to their customers and employees who encounter risky situations when visiting this business unit.
Security helps the organization meet its business objectives or mission by protecting its physical and financial resources, reputation, legal position, employees, and other tangible and intangible assets through the selection and application of appropriate safeguards. Businesses should establish roles and responsibilities of all personnel and staff members. However, a Chief Information Officer should be appointed to direct an organization’s day to day management of information assets. Supporting roles are performed by the service providers and include systems operations, whose personnel design and operate the computer systems. Each team member must be held accountable in ensuring all of the rules and policies are being followed, as well as, understanding their roles, responsibilities and functions. Organizations information processing systems are vulnerable to many threats that can inflict various types of damage that can result in significant losses (Harris, 2014). Losses can come from actions from trusted employees that defraud the system, outside hackers, or from careless data entry. The major threat to information protection is error and omissions that data entry personnel, users, system operators and programmers make. To better protect business information resources, organizations should conduct a risk analysis to see what
Due in Week Seven: Outline the Access Control Policy. Describe how access control methodologies work to secure information systems
Authorization controls to restrict access to authorized users. These controls are implemented with an access control matrix and compatibility tests.
The topic of network security is a reoccurring theme in today’s business world. There is an almost unfathomable amount of data generated, transmitted, and stored every day. Unfortunately the media and traditional reporting sources these days typically only focus on outside threats such as hackers. Many people completely overlook the insider threats that are present and can potentially pose and even bigger threat then any outside source. One of the acronyms that is constantly repeated in the security industry is the principle of CIA or confidentiality, integrity, and availability. Authorized users, whether by accident or through malicious acts, are in a unique position to threaten all three aspects of CIA.
Permission-based Access Control: The problem with this approach is that it relies upon user to make security decisions, and decide whether an app’s requested combination of permissions is safe or not.
“To assist organizations in making the appropriate selection of security controls for information systems, the concept of baseline controls is introduced. Baseline controls are the starting point for the security control selection process (Gallagher, 2015)”. “There are three distinct types of security control designations related to the security controls that define: (1) the scope of applicability for the control; (2) the shared nature of the control; and (3) the responsibility for control development, implementation, assessment, and authorization (Gallagher, 2015)”.The security control designations include common controls, system-specific controls, and hybrid
This paper includes the comparison between access control models Mandatory Access Control (MAC), Discretionary Access Control (DAC) and Role Based Access Control (RBAC) and explores the advantages and disadvantages of implementing the subjected models. They provides the fundamental policy and rules for the system level access control. . Role-based access control has been presented alongside claims that its strategies and working are common enough to integrate the customary access control models: mandatory access control (MAC) and discretionary access control (DAC).the aim is
The Risk Management Framework and associated RMF tasks apply to both information system owners and common control providers. In addition to supporting the authorization of information systems, the RMF tasks support the selection, growth, execution, assessment, authorization, and ongoing monitoring of common controls inherited by organizational information systems. Internal and external to the organization, helps ensure that the security abilities provided by the common controls can be congenital by information system owners with a degree of assurance appropriate for their information protection needs. (Locke & Gallagher,

... web services[16]. This architecture extended Role-Based Access Control(RBAC) with location constraints, and applied it as the access control middleware. When a service sends a request for the privacy data, the privacy access control middleware will be invoked and enforced by the location constraints. It will make the decision based on the purposes, recipients, obligations, retentions and other components of the core RBAC model, to grant or reject the access request, and send obligations and retention in the response. The entire mechanism is depicted in the Fig.9.
The first thing that we must consider about Information Security is that there is not a final destination at which we can arrive. IT Security is an ongoing set of processes and activities that requires attention and expertise on a daily basis. It is important to understand that systems are not secured by themselves and it is our responsibility to maintain and improve them periodically as required. It is of vital importance to establish the appropriate mechanisms and requirements in order to support the company’s CIA triad. The following report will provide you guidance about auditing and hardening techniques applied though the 7 Domains by utilizing IT Security Best Practices.
Privacy exist wherever personal information or other sensitive information is collected, stored, used, and finally destroyed or deleted – in digital form or otherwise. The challenge of data privacy is to use data while safe-guarding individual's privacy preferences and their personally identifiable information. The fields of computer security, data security, and information security design and utilize software, hardware, and human resources to address this issue.
