But, if the intruder gets the algorithm of the sentinel application on data, then the data can be breached easily. Hence, it appeared ineffective in due course of time. Thus a need of specific system rose to have such process which can monitor the cloud without adding any sentinels. Hence, demand of more improvised Auditor emerged which can provide effective integrity assurance for database services. Due to absence of such Auditor, have led to many inevitable situations, for example, recently a big robbery of data had occurred in the South Korea of three major banks. It had shown major drawbacks in the security and storage mechanism of IT infrastructure. The data which was robbed contained information like monthly card usage, card numbers, salaries etc, which had led to a lot of tension among the account holders. The card holders were running towards the bank for cancelling the card, so that no money from their account could be transferred. This episode pro-vided a lesson to keep the storage servers watertight, protected and detect prohibited action of culprits. In IT industry, large improvements in authentication system, firewalls and data access has to be made to avoid such incident in future. The presented work checks the integrity of data, so that no part of data could be modified, deleted and inserted without user permission. This paper provides users, the freedom of examining the integrity which observes indifferently toward both Cloud service providers (CSP) as well Data Owners. Monitoring of data needs requires profound study of database storage as well as methods of data transfer and access which is a very complex job. The methods must be reliable and must be transparent so that questions will not arise on the way of work...

...may be completely or partially deleted for saving space and maintenance cost, the user came to know only when it tries to retrieve it. The goal of the paper is provide such an automatic mechanism which is impartial to both and follow the simple and efficient methods that are fast and error-free which provide notifications to user when Data Storage System behaves illicitly. To make the Audit system more effective the various obstacles and opportunities like Data lock-in, Data transfer bottlenecks, etc., in Cloud are considered [10].
The rest of the paper structured as follows: In, Section II explain research background and related work. Section III addresses audit techniques and system architecture with actual implementation. In, Section IV the experimental results were discussed along with limitations and future work in Section V and finally conclude in Section VI.
Auditing enhanced the security in an infrastructure by giving Systems Administrators a closer look of events occurring in their infrastructure. It gives them a history of a certain user’s or computer’s activates and allow them to watch out for intruders’ events and preventing unauthorized access to a certain object in the infrastructure. Best practices of auditing are making an auditing plan at first where Systems Administrators can define what items to audit. In most cases, Systems Administrators should at least archive security logs and audit them, audit login activates, and audit applications logs. Additionally, policy change events must be audited to insure that users can never change the Local Security Authority (LSA). This auditing option allows Systems Administrators to insure that users do not go around enforced polices and cause a security issue to the
Every piece of information must be traceable back to the data input that produced it. The main action of audit trail is captures a sources of all data items at the time of getting entrance into the system. The other constituent of input control and security involves data security rules and measures to protect data from being or lost or damaged. The records retention policy is the practice of storing documents in a safe location and making sure to see to legal requirements or business needs. Input security and control also involves the process of encrypting or encryption of data so only users with the code it software can read
There are several important people involved with this project and will help with the necessary changes needed for the Payable Audit System (PAS). Each person has a very detailed job description and the skills that would be used to make the changes to the system. First, Ted Anderson the director of disbursement began to notice how their current system was very labor-intensive. He knew of other ways to increase the productivity to the system and he would help in the plan to transform these changes. First, he changed the mind-set of how the system would work, and he organized a difficult training course with a 9 month duration designed for the employees. With his role on this project the company will make several fundamental changes, to pay the invoices in their tolerance. Keeping all history transactions, they would adopt a quality-control approach. Also eliminating all their paper files they would develop a Document Control System (DCS), where they would scan all of their documents into their computer system.
This document will outline the policies and practices to be used and implemented in compliance with DoD specifications and standards for the contract of services to be provided to them. This report will consist of creating security controls based on auditing frameworks within the seven domains. Also to develop information assurance (IA) plan, a list of the requirements for each of the seven domains.
List and briefly describe the elements of the 7 Component Framework Industry Standards for Auditing and Monitoring
...ken offline and the physical disk(s) stored properly, but also time is of the essence for collection procedures. Another factor in forensic is the evidence Retention, CIRT should establish a chain of custody to document who has had custody from time of discovery to presentation in court. Additional evidence such as logs from firewalls, IDS, and sniffers are useful, and all systems should use Network Time Protocol or other form of authoritative time stamps. Additionally, accountability is the foundation for incident response and forensics, and logging is the way to produce full accountability in case of an incident. Also, the primary way of protecting logs is via file-system permissions, and the process writing the log should only be able to write. Then, administrators should only be able to read logs. Other approaches include WORM media such as CD-ROM and printers.
The cloud storage services are important as it provides a lot of benefits to the healthcare industry. The healthcare data is often doubling each and every year and consequently this means that the industry has to invest in hardware equipment tweak databases as well as servers that are required to store large amounts of data (Blobel, 19). It is imperative to understand that with a properly implemented a cloud storage system, and hospitals can be able to establish a network that can process tasks quickly with...
Data encryption refers to the process of transforming electronic information into a scrambled form that can only be read by someone who knows how to translate the code. In nowadays business world, it’s the easiest and most practical way to secure the information that we stored and processed, and it’s significant for our sensitive information. For example, as electronic commerce is popular now, the vendors and retailers must protect the customers’ personal information from hackers or competitors. They also have many business files or contracts that need to be strictly protected. Without data encryption, these important information may fall into wrong hands and be misused by others. Besides, data encryption may be used to secure sensitive information that exists on company networks, or create digital signatures, and help to authorize in business. No one should underestimate the importance of encryption. A little mistake in encryption may make sensitive information revealing, or even result in illegal and criminal accuse.
In a world that is run by computers, perhaps one of the most frustrating things that can happen to a person is waking up to find out the hard drive on their computer has stopped working, and all of their files inaccessible. In the event of such a failure, many people would view the situation as beyond remedy, and resign themselves to simply dealing with the loss. This however does not need to be the case. Although recovering files from a hard drive is not always possible, there are steps that can be taken to give yourself a chance to recover everything you believe to be lost. This paper will discuss various possible solutions to hard drive failure, and will detail steps that can be taken to secure your data.
...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.
Despite the numerous advantages offered by cloud computing, security is a big issue concerned with cloud computing. There are various security issues and concerns associated with cloud computing, among them being phishing, data loss and data privacy. There are different mitigation measures that cloud pioneers are currently using to ensure data stored in the cloud remain secure and confidential as intended. Encryption is one mitigation method used to ensure security in cloud computing. According to Krutz and Vines (2010), encryption involves coding of the data stored in the computing cloud such that hackers cannot gain access to the data. Data encryption seems to be the most effective method of ensuring security in computing (Krutz and Vines, 2010). However, it is of paramount importance to note that encrypted data is usually difficult to search or perform various calculations on it.
By Systems Auditing: Comparing the internal quality system i.e. is the quality system followed by the company to the external quality standards. This not only helps the company have better processes but also sets a bar for the suppliers to match up to their expectations.
The aim of this report is to theoretical cover data preservation, examination of digital evidence, tools and techniques for data capture, preservation and examination with a list of recommendations.
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.
The major characters of the tradition audit are all information what is needed by auditors are on the paper and the manual calculators and without high communication technology. Auditors usually were limited by the place in the paper time. When a several people are working on the same auditing project for a client with offices in cities across the country, even worldwide, it takes a lots all time those auditors get the information which they need from the client, even there is risk paper information disappear for many reasons. on the another hand, mail paper information increase the auditing cost. The mistake caused by the manual calculators inevitably, no matter how fixed auditors concentrate on recalculate is, after all auditors are human. The global business become major in the modern business world, some example, several auditors who are in different locations are working a same auditing project, or auditors are in different city even country with the client, when there is issue among these auditors or between auditors and client, they only can communicate with each other by phone or be together and have meeting. Phone call can not make sure information been watched in the same time when the voice is talking about the issue, but having a meeting takes time and money make all people together, it increases auditing cost.
