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.
IDS is a device or software application that monitors a network for an unauthorised attack.
DWP Systems performed an outer security helplessness evaluation of ABC association. An outside appraisal takes a gander at gadgets, for example, firewalls, servers and switches that give administrations on the Internet. It likewise covers application layer appraisals on any online administrations remotely confronting. We additionally take a gander at the workstations in your association and how they are being utilized by the clients. The physical building is additionally examined for any passageways and exits. This is to guarantee that the building that is lodging the information and data is secured also.
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
In this case, a large health services organization (HSO) in Florida, that has a world-renowned AIDS treatment center had information breach of 4,000 HIV+ patient records, and the list was sent to newspapers, magazines, and the internet. Consequently, this issue was featured in every media vehicle in the world and as CEO, you are requested by the board of trustees to come up a better management information system (MIS) to resolve all information security issues or you will face termination. After hiring an undercover computer security consultant to help determine where the security leak came from, she quickly identifies numerous breaches in computer security and provides a report with the issues identified. The report furnished by the consultant revealed that facility had major problems with the MIS and the staff. In order to determine how to address the issues, the CEO must first answer the following questions: what law is being violated by the employees, why was this law enacted, what are the penalties for such violations, what are the penalties for sharing celebrity information, and should he be updating his resume and looking for another job (Buchbinder, 378).
In 1980, James Anderson’s paper, Computer Security Threat Monitoring and Surveillance, bore the notion of intrusion detection. Through government funding and serious corporate interest allowed for intrusion detection systems(IDS) to develope into their current state. So what exactly is IDS? An IDS is used to detect malicious network traffic and computer usage through attack signatures. The IDS watches for attacks not only from incoming internet traffic but also for attacks that originate in the system. When a potential attack is detected the IDS logs the information and sends an alert to the console. How the alert is detected and handled at is dependent on the type of IDS in place. Through this paper we will discuss the different types of IDS and how they detect and handle the alerts, the difference between a passive and a reactive system and some general IDS intrusion invasion techniques.

Although Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) have been grouped together here (IDPS), there are distinctions between them. On the most basic level, both will monitor the network...
When someone suspects that an unauthorized, unacceptable, or unlawful event has occurred involving an organization’s computer networks or data-processing equipment Computer security incidents are normally identified. Initially, the incident may be reported by an ultimate user, detected by a system administrator, identified by IDS alerts, or discovered
...t to track all Internal and External users activity, auditing plays the key role in monitoring these user actions. Data masking and encryption technology provide certain level of assurance that data is not easily accessible to unauthorized users.
Auditing has been the backbone of the complicated business world and has always changed with the times. As the business world grew strong, auditors’ roles grew more important. The auditors’ job became more difficult as the accounting principles changed. It also became easier with the use of internal controls, which introduced the need for testing, not a complete audit. Scandals and stock market crashes made auditors aware of deficiencies in auditing, and the auditing community was always quick to fix those deficiencies. Computers played an important role of changing the way audits were performed and also brought along some difficulties.

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.
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.
