80-486: IT audits are also known as automated data processing audits ( ADP audits ) and computer audits . They were formerly called electronic data processing audits ( EDP audits ). An IT audit is different from a financial statement audit . While a financial audit's purpose is to evaluate whether the financial statements present fairly, in all material respects, an entity's financial position, results of operations, and cash flows in conformity to standard accounting practices ,

160-484: A broader range of operations such as monitoring IT infrastructures, detecting attacks or breaches, and responding to security failures. The spread of cyber risk across all organizational activities, the external nature of many of the risks, and the rate of change in the risk are just a few of the issues that organizations face in developing effective risk management around cyber security. Numerous banks and financial organizations are studying blockchain security solutions as

240-530: A great improvement in the audit process overall. The use of computer-assisted audit techniques (CAATs) have allowed companies to examine larger samples of data and more thorough reviews of all transactions, allowing the auditor to test and better understand any issues within the data. The use of IT systems in audits has transformed the way auditors accomplish important audit functions such as the management of databases, risk assurance and controls, and even governance and compliance. In addition, IT audit systems improve

320-573: A lot to offer. The way businesses are performed and data is analyzed is changing as a result of technological advancements. Data management is becoming increasingly important. Artificial intelligence, blockchain, and data analytics are major changers in the accounting and auditing industries, altering auditors' roles. The introduction of cloud computing and cloud storage has opened up previously unimaginable possibilities for data collection and analysis. Auditors can now acquire and analyze broader industry data sets that were previously unreachable by going beyond

400-399: A means of mitigating risk, cyber risks, and fraud. While these latter systems are less susceptible to cyberattacks that may bring the entire network down, security concerns remain, as a successful hack would allow access to not just the data saved at a particular point, but to all data in the digital ledger. SSAE 16 Statement on Standards for Attestation Engagements no. 16 (SSAE 16)

480-459: A number of provisions of the Act (e.g. the willful destruction of evidence to impede a federal investigation) that apply to privately held companies. SSAE 16 reporting can help service organizations comply with Sarbanes–Oxley 's requirement (section 404) to show effective internal controls covering financial reporting. It can also be applied to data centers or any other service that might be used in

560-495: A part of the overall external auditing performed by a Certified Public Accountant (CPA) firm. ) IS auditing considers all the potential hazards and controls in information systems. It focuses on issues like operations, data, integrity, software applications, security, privacy, budgets and expenditures, cost control, and productivity. Guidelines are available to assist auditors in their jobs, such as those from Information Systems Audit and Control Association. The concept of IT auditing

640-615: A result of the increased use of IT systems in audits, authoritative bodies such as the American Institute of Certified Public Accountants (AICPA) and the Information Systems Audit Control Association (ISACA) have established guidance on how to properly use IT systems to perform audits. Auditors must now adhere to the established guidelines when utilizing IT systems in audits. The use of IT systems and AI techniques on financial audits

720-577: A result, enterprise communications audits are still manually done, with random sampling checks. Policy Audit Automation tools for enterprise communications have only recently become available. The Use of Artificial Intelligence (AI) in IT audits is growing rapidly, with 30% of all corporate audits to be conducted using AI by 2025 as reported by the World Economic forum from 2015. AI in IT audits raises many ethical issues. Globalization in combination with

These firms coordinate services performed by local firms within their respective areas but do not perform services or hold ownership in the local entities. This group was once known as the "Big Eight", and was reduced to the "Big Six" and then "Big Five" by a series of mergers . The Big Five became the Big Four after the demise of Arthur Andersen in 2002, following its involvement in

880-769: A viable business through auditing revenue may be weighed against its duty to examine and verify the accuracy, relevancy, and completeness of the company's financial statements. This is done by auditor. Numerous proposals are made to revise the current system to provide better economic incentives to auditors to perform the auditing function without having their commercial interests compromised by client relationships. Examples are more direct incentive compensation awards and financial statement insurance approaches. See, respectively, Incentive Systems to Promote Capital Market Gatekeeper Effectiveness and Financial Statement Insurance. Currently, many entities being audited are using information systems, which generate information electronically. For

The rise of VOIP networks and issues like BYOD and the increasing capabilities of modern enterprise telephony systems causes increased risk of critical telephony infrastructure being misconfigured, leaving the enterprise open to the possibility of communications fraud or reduced system stability. Banks, financial institutions, and contact centers typically set up policies to be enforced across their communications systems. The task of auditing that

1040-408: Is a fundamental shift in the way records are created, maintained, and updated. Blockchain records are distributed among all users rather than having a single owner. The blockchain approach's success is based on the employment of a complicated system of agreement and verification to ensure that, despite the lack of a central owner and time gaps between all users, a single, agreed-upon version of the truth

1120-420: Is a profession known for its male dominance. According to the latest survey, it found that 70–80% of financial auditors are male, with 2% being female and the rest being a mixture of both (Bader, 2018). Greenwood et al. (1990) defined the audit firm as, "a professional partnership that has a decentralized organization relationship between the national head office and local offices". Local offices can make most of

1200-822: Is a reference to the Auditor of the Exchequer in England in 1314. The Auditors of the Impresa were established under Queen Elizabeth I in 1559 with formal responsibility for auditing Exchequer payments. This system gradually lapsed and in 1780, Commissioners for Auditing the Public Accounts were appointed by statute. From 1834, the Commissioners worked in tandem with the Comptroller of the Exchequer, who

1280-524: Is also able to verify the authenticity of transactions in real time, giving it the ability to alert necessary parties for fraud. This helps improve the audit process and the accuracy of the audit. Before, auditors had to manually go through thousands of entries in a sample and now with blockchain technology, every single transaction is verified as soon as it is entered. Cyber security protects networks, systems, devices, and data from attack, unauthorized access, and harm. Cyber security best practices also include

1360-473: Is an auditing standard for service organizations, produced by the American Institute of Certified Public Accountants (AICPA) Auditing Standards Board , which supersedes Statement on Auditing Standards no. 70 (SAS 70) and has been superseded by SSAE No. 18 . The "service auditor’s examination" of SAS 70 is replaced by a System and Organization Controls ( SOC ) report. SSAE 16

1440-634: Is an independent snapshot of the organization's control landscape on a given day. A SOC 1 Type 2 report adds a historical element, showing how controls were managed over time. The SSAE 16 standard requires a minimum of six months of operation of the controls for a SOC 1 Type 2 report. Public companies in the United States fall under the Public Company Accounting Reform and Investor Protection Act , also known as Sarbanes–Oxley or SOX. However, there are also

One result of this scandal was that Arthur Andersen , then one of the five largest accountancy firms worldwide, lost their ability to audit public companies, essentially killing off the firm. A recent trend in audits (spurred on by such accounting scandals as Enron and Worldcom ) has been an increased focus on internal control procedures, which aim to ensure

1600-455: Is necessary to combine the information obtained to reach an overall conclusion as to whether the financial statements are fairly presented. This highly subjective process relies heavily on the auditor's professional judgment. When the audit is completed, the CPA must issue an audit report to accompany the client's published financial statements. Corporations Act 2001 requires the auditor to: One of

1680-557: Is omni-channel, where interaction takes place across multiple channels, not just over the telephone. One of the key issues that plagues enterprise communication audits is the lack of industry-defined or government-approved standards. IT audits are built on the basis of adherence to standards and policies published by organizations such as NIST and PCI , but the absence of such standards for enterprise communications audits means that these audits have to be based an organization's internal standards and policies, rather than industry standards. As

1760-531: Is one of many assurance functions provided by accounting firms. Many organizations separately employ or hire internal auditors , who do not attest to financial reports but focus mainly on the internal controls of the organization. External auditors may choose to place limited reliance on the work of internal auditors. Auditing promotes transparency and accuracy in the financial disclosures made by an organization, therefore would likely reduce such corporations concealment of unscrupulous dealings. Internationally,

Each is a network of firms, owned and managed independently, which have entered into agreements with other member firms in

2000-464: Is starting to show huge benefits for leading accounting firms. In a study done by one of the Big 4 accounting firms, it is expected that the use of IT Systems and AI techniques will generate an increase of $ 6.6 trillion in revenue as a result of the increase in productivity. As a result, leading auditing firms are making enormous investments with the goal of increasing productivity and therefore revenue through

2080-412: Is to work with business groups to make authorized access and reporting as straightforward as possible. To use a simple example, users should not have to do their own data matching so that pure relational tables are linked in a meaningful way. IT needs to make non-normalized, data warehouse type files available to users so that their analysis work is simplified. For example, some organizations will refresh

2160-630: Is usually a part of accounting internal auditing, and is frequently performed by corporate internal auditors. An external auditor reviews the findings of the internal audit as well as the inputs, processing and outputs of information systems. The external audit of information systems is primarily conducted by certified Information System auditors, such as CISA, certified by ISACA, Information System Audit and Control Association , USA, Information System Auditor (ISA) certified by ICAI (Institute of Chartered Accountants of India), and other certified by reputed organization for IS audit.

2320-613: The International Standards on Auditing (ISA) issued by the International Auditing and Assurance Standards Board (IAASB) is considered as the benchmark for audit process. Almost all jurisdictions require auditors to follow the ISA or a local variation of the ISA. Financial audits exist to add credibility to the implied assertion by an organization's management that its financial statements fairly represent

2400-630: The Securities Act of 1933 and the Securities Exchange Act of 1934 were enacted by President Franklin D. Roosevelt. The latter created the Securities and Exchange Commission, which required all current and new registrants to have audited financial statements. In doing so, the services that CPAs could provide became more valued and requested. In the United States, the accounting and auditing profession reached its peak from

2480-459: The 1940s to the 1960s. The SEC was reliant on the Institute for the auditing procedures used by accounting firms during engagements. Additionally, in 1947 a committee from the Institute advocated for "generally accepted auditing standards", which were approved in the following year. These standards governed the terms of the auditor's performance relating to professional conduct and the execution of

2560-478: The Australian Government. The origins of financial audit begin in the 1800s in England, where the need for accountability first arose. As people began to recognize the benefits of financial audits, the need for standardization became more apparent and the use of financial audits spread into the United States. In the early 1900s financial audits began to take on a form more resembling what is see in

2640-419: The United States in the late nineteenth century. These practices came by way of British and Scottish investors who wanted to stay more informed on their American investments. Around this same time, an American accounting system was taking root. Within the next 10 years (1896), professionals had the opportunity to become accredited by obtaining a license to become a Certified Public Accountant. Copious amounts of

According to these, the importance of IT audit is constantly increased. One of the most important roles of the IT audit is to audit over the critical system in order to support

2800-520: The article detailed the flaws of the auditing system. While others in the industry agreed with Smith's comments, many believed standardization was impossible. As the reputation of accounting firms grew, federal agencies began to seek out their advice. The Federal Trade Commission (FTC) and the Federal Reserve Board inquired about auditing procedures by requesting a technical memorandum in 1917. The Institute provided this guidance, which

2880-458: The audit committee. The fees are set at a level that could not lead to audit quality being compromised. The scarcity of staffs and the lower audit fee lead to very low billing realization rates. As a result, accounting firms, such as KPMG, PricewaterhouseCoopers and Deloitte who used to have very low technical inefficiency, have started to use AI tools. The earliest surviving mention of a public official charged with auditing government expenditure

There are less paper documents and pre-numbered audit evidences available, which leads a revolution to audit mythology. Over the past couple of years, technology is becoming a bigger emphasis for the audit profession, professional bodies, and regulators. From operational efficiency to financial inclusion and increased insights, technology has

Examples of such audits are SSAE 16 , ISAE 3402 , and ISO27001:2013 . The extension of the corporate IT presence beyond the corporate firewall (e.g. the adoption of social media by the enterprise along with the proliferation of cloud-based tools like social media management systems ) has elevated

3120-631: The auditing work done at the end of the 19th century were by chartered accountants from England and Scotland. This included the work of Arthur Young, Edwin Guthrie, and James T. Anyon. In the 1910s financial audits came under scrutiny for their unstandardized practices of accounting for various items, including tangible and intangible assets. Notably was the article "The Abuse of the Audit in Selling Securities" written by Alexander Smith in 1912,

3200-690: The auditor's judgment during engagements. In the United States, the SEC has generally deferred to the accounting industry (acting through various organizations throughout the years) as to the accounting standards for financial reporting, and the U.S. Congress has deferred to the SEC. This is also typically the case in other developed economies. In the UK, auditing guidelines are set by the institutes (including ACCA , ICAEW , ICAS and ICAI) of which auditing firms and individual auditors are members. While in Australia,

3360-406: The cash basis or some other basis of accounting appropriate for the organization. In providing an opinion whether financial statements are fairly stated in accordance with accounting standards, the auditor gathers evidence to determine whether the statements contain material errors or other misstatements. The audit opinion is intended to provide reasonable assurance, but not absolute assurance, that

This emphasis on the internal control environment is now a mandatory part of the audit of SEC-listed companies, under the auditing standards of the Public Company Accounting Oversight Board (PCAOB) set up by the Sarbanes–Oxley Act . Many countries have government sponsored or mandated organizations who develop and maintain auditing standards, commonly referred to generally accepted auditing standards or GAAS. These standards prescribe different aspects of auditing such as

3680-832: The constraints of business data. As a result, auditors are better equipped to spot data anomalies, create business insights, and focus on business and financial reporting risk. This refers to machines that do tasks that need some kind of 'intelligence,' which can include learning, sensing, thinking, creating, attaining goals, and generating and interpreting language. Recent advances in AI have relied on approaches like machine learning and deep learning, in which algorithms learn how to do tasks like classify objects or predict values through statistical analysis of enormous amounts of data rather than explicit programming. Machine learning uses data analytics to simultaneously and continuously learn and identify data patterns allowing it to make predictions based on

3760-577: The cost of capital of the preparer of the financial statements. In accordance with the US Generally Accepted Accounting Principles (US GAAP), auditors must release an opinion of the overall financial statements in the auditor's report . Auditors can release three types of statements other than an unqualified/unmodified opinion: Financial audits are typically performed by firms of practicing accountants who are experts in financial reporting. The financial audit

3840-459: The data. Currently, Deloitte and PricewaterhouseCoopers (PWC) are both using machine learning tools within their companies to aid in financial auditing. Deloitte uses a software called Argus, which reads and scans documents to identify key contract terms and other outliers within the documents. PWC uses Halo, which is another machine learning technology that analyzes journal entries in the accounting books to identify areas of concern. Blockchain

3920-562: The delivery of financial reporting. For reports that are not specifically focused on internal controls over financial reporting, the American Institute of Certified Public Accountants (AICPA) has issued an Interpretation under AT Section 101 permitting service auditors to issue reports. These reports will now be considered SOC 2 audits and focus on controls at a service organization relevant to security, availability, processing integrity, confidentiality, or privacy. SSAE 16 provides guidance on an auditing method, rather than mandating

4000-401: The development or outsourcing of IT systems and AI techniques to assist in financial audits. PwC, one of the biggest auditing firms in the world, has narrowed down three different types of IT systems and AI techniques that firms can develop and implement to achieve increased revenue and productivity. The first system is by created in a way that technology systems that play a supplemental role in

The purpose of an audit is to provide an objective independent examination of the financial statements, which increases the value and credibility of the financial statements produced by management, thus increase user confidence in the financial statement, reduce investor risk and consequently reduce

4240-415: The first corporation was formed. The law required auditors who owned a share of the company but who did not directly manage the company's operations. Audit financial documents had been presented to shareholders, but at this point anyone could be an auditor. In these early days there was little accountability or standardization. Financial auditing, and various other English accounting practices, first came to

4320-404: The following: Will the organization's computer systems be available for the business at all times when required? (known as availability) Will the information in the systems be disclosed only to authorized users? (known as security and confidentiality) Will the information provided by the system always be accurate, reliable, and timely? (measures the integrity) In this way, the audit hopes to assess

4400-415: The growth in information technology systems has caused companies to shift to an increasingly digitized working environment. Advantages provided by these systems include a reduction in working time, the ability to test large amounts of data, reduce audit risk, and provide more flexible and complete analytical information. With an increase in time, auditors are able to implement additional audit tests, leading to

4480-432: The human auditors decision-making. This allows the human auditor to retain autonomy over decisions and use the technology to support and enhance their ability to perform accurate work, ultimately saving the firm in productivity costs. Next, PwC states that systems with problem solving abilities are imperative to producing the most accurate results. PwC recognizes the increased margin for error due to unintended biases, and thus

4560-547: The importance of incorporating web presence audits into the IT/IS audit. The purposes of these audits include ensuring the company is taking the necessary steps to: The use of departmental or user developed tools has been a controversial topic in the past. However, with the widespread availability of data analytics tools, dashboards, and statistical packages users no longer need to stand in line waiting for IT resources to fulfill seemingly endless requests for reports. The task of IT

4640-402: The major issues faced by private auditing firms is the need to provide independent auditing services while maintaining a business relationship with the audited company. The auditing firm's responsibility to check and confirm the reliability of financial statements may be limited by pressure from the audited company, who pays the auditing firm for the service. The auditing firm's need to maintain

4720-457: The managerial decisions except for the drawing up of professional standards and maintaining them. The Big Four are the four largest international professional services networks , offering audit , assurance, tax, consulting, advisory, actuarial, corporate finance, and legal services. They handle the vast majority of audits for publicly traded companies as well as many private companies , creating an oligopoly in auditing large companies. It

4800-638: The member firms. They are similar to law firm networks found in the legal profession. In many cases each member firm practices in a single country, and is structured to comply with the regulatory environment in that country. In 2007 KPMG announced a merger of four member firms (in the United Kingdom, Germany, Switzerland and Liechtenstein ) to form a single firm. Ernst & Young also includes separate legal entities which manage three of its four areas: Americas, EMEIA (Europe, The Middle East, India and Africa), and Asia-Pacific . (The Japan area does not have

4880-485: The need for IT audits to check businesses IT system performances and to lower the probability and impact of technology threats and disruptions. The primary functions of an IT audit are to evaluate the systems that are in place to guard an organization's information. Specifically, information technology audits are used to evaluate the organization's ability to protect its information assets and to properly dispense information to authorized parties. The IT audit aims to evaluate

4960-512: The need for creating systems that are able to adapt to different scenarios. This type of system requires decision making to be shared between the human auditor and the IT system to produce the maximum output by allowing the system to take over the computing work that could not be one by a human auditor alone. Finally, PwC recognizes that there are scenarios where technology needs to have the autonomy of decision making and act independently. This allows human auditors to focus on more important tasks while

5040-447: The network to share a common name, brand and quality standards. Each network has established an entity to co-ordinate the activities of the network. In one case (KPMG), the co-ordinating entity is Swiss, and in three cases (Deloitte Touché Tohmatsu, PricewaterhouseCoopers and Ernst & Young) the co-ordinating entity is a UK limited company . Those entities do not themselves perform external professional services, and do not own or control

5120-426: The operational efficiency and aid in decision making that would otherwise be left to hand-held calculations. IT systems help to eliminate the human error in audits and while it does not fully solve the issue, IT systems have proven to be helpful in audits done by the Big 4 and small firms alike. These systems have greatly reduced the margin of error on audits and provide a better insight into the data being analyzed. As

5200-468: The opinion, stages of an audit, and controls over work product ( i.e. , working papers ). Some oversight organizations require auditors and audit firms to undergo a third-party quality review periodically to ensure the applicable GAAS is followed. The following are the stages of a typical audit: Notes: Notes: After the auditor has completed all procedures for each audit objective and for each financial statement account and related disclosures, it

5280-442: The organization's position and performance to the firm's stakeholders. The principal stakeholders of a company are typically its shareholders, but other parties such as tax authorities, banks, regulators, suppliers, customers and employees may also have an interest in knowing that the financial statements are presented fairly, in all material aspects. An audit is not designed to provide absolute assurance, being based on sampling and not

5360-489: The profit and loss statement and the balance sheet. The memorandum was revised and published making it the first authoritative guidance published in the United States in regard to auditing procedures. It was not until 1932, when the New York Stock Exchange began requiring financial audits, that the practice started to standardize. It did not become a requirement for newly listed companies until 1933 when

5440-631: The purposes of an IT audit is to evaluate the system's internal control design and effectiveness. This includes, but is not limited to, efficiency and security protocols, development processes, and IT governance or oversight. Installing controls are necessary but not sufficient to provide adequate security. People responsible for security must consider if the controls are installed as intended, if they are effective, or if any breach in security has occurred and if so, what actions can be done to prevent future breaches. These inquiries must be answered by independent and unbiased observers. These observers are performing

5520-544: The risk to the company's valuable asset (its information) and establish methods of minimizing those risks. More specifically, organizations should look into three major requirements: confidentiality, integrity, and availability to label their needs for security and trust in their IT systems. These three requirements should be emphasized in every industry and every organization with an IT environment but each requirements and controls to support them will vary. Various authorities have created differing taxonomies to distinguish

5600-533: The rules and professional code of ethics are set by The Institute of Chartered Accountants Australia (ICAA), CPA Australia (CPA) and The National Institute of Accountants (NIA). Accordingly, financial auditing standards and methods have tended to change significantly only after auditing failures. The most recent and familiar case is that of Enron . The company succeeded in hiding some important facts, such as off-book liabilities, from banks and shareholders. Eventually, Enron filed for bankruptcy, and (as of 2006 )

5680-505: The task of information systems auditing. In an Information Systems (IS) environment, an audit is an examination of information systems, their inputs, outputs, and processing. As technology continues to advance and become more prevalent in our lives and in businesses, along comes an increase of IT threats and disruptions. These impact every industry and come in different forms such as data breaches, external threats, and operational issues. These risks and need for high levels of assurance increase

5760-469: The technology takes care of time consuming tasks that do not require human time. The utilization of IT systems and AI techniques on financial audits extend past the goal of reaching maximized productivity and increased revenue. Firms who utilize these systems to assist in the completion of audits are able to identify pieces of data that may constitute fraud with higher efficiency and accuracy. For example, systems such as drones have been approved by all four of

5840-776: The testing of all transactions and balances; rather it is designed to reduce the risk of a material financial statement misstatement whether caused by fraud or error. A misstatement is defined in ISA 450 as an error, omitted disclosure or inappropriate accounting policy. "Material" is an error or omission that would affect the users decision. Audits exist because they add value through easing the cost of information asymmetry and reducing information risk, not because they are required by law (note: audits are obligatory in many EU-member states and in many jurisdictions are obligatory for companies listed on public stock exchanges). For collection and accumulation of audit evidence, certain methods and means generally adopted by auditors are: Financial audit

5920-415: The twenty-first century. The first laws surrounding audit formed in England in the beginning of the nineteenth century and helped the financial sector in England prosper. To fully gain the trust of the public, the auditor profession would need to grow and standardize itself and establish organizations, becoming equally accountable across the country and the world. In 1845 England, accompanied by new law,

6000-564: The type of audit to be performed, especially in the IT realm. Many frameworks and standards try to break controls into different disciplines or arenas, terming them “Security Controls“, ”Access Controls“, “IA Controls” in an effort to define the types of controls involved. At a more fundamental level, these controls can be shown to consist of three types of fundamental controls: Protective/Preventative Controls, Detective Controls and Reactive/Corrective Controls. In an IS, there are two types of auditors and audits: internal and external. IS auditing

6080-572: The various types of IT audits. Goodman & Lawless state that there are three specific systematic approaches to carry out an IT audit: Others describe the spectrum of IT audits with five categories of audits: And some lump all IT audits as being one of only two type: " general control review " audits or " application control review " audits. A number of IT audit professionals from the Information Assurance realm consider there to be three fundamental types of controls regardless of
