PSA 401: AUDITING IN A COMPUTER INFORMATION SYSTEMS ENVIRONMENT

By: Abilay, Runith

The auditor should consider how a CIS environment affects the audit.

Procedures followed by the auditor in obtaining a sufficient understanding of the accounting and internal control systems.

Consideration of inherent risk and control risk through which the auditor arrives at the risk assessment.

Auditor’s design and performance of tests of control and substantive procedures appropriate to meet the audit objective

CIS Environment may affect:

The overall objective and scope of an audit does not change in a CIS environment. However, the use of a computer changes the processing, storage and communication of financial information and may affect the accounting and internal control systems employed by the entity.

The auditor should have sufficient knowledge of the CIS to plan, direct, supervise and review the work performed. The auditor should consider whether specialized CIS skills are needed in an audit.

Obtain a sufficient understanding of the accounting and internal control systems affected by the CIS environment.

Determine the effect of the CIS environment on the assessment of overall risk and of risk at the account balance and class of transactions level.

Design and perform appropriate tests of control and substantive procedures.

Skills and Competence:

If specialized skills are needed, the auditor would seek the assistance of a professional possessing such skills, who may be either on the auditor’s staff or an outside professional.

Skills and Competence:

If the use of such a professional is planned, the auditor should obtain sufficient appropriate audit evidence that such work is adequate for the purposes of the audit, in accordance with ISA 620, “Using the Work of an Expert.”

In accordance with ISA 400 “Risk Assessments and Internal Control,” the auditor should obtain an understanding of the accounting and internal control systems sufficient to plan the audit and develop an effective audit approach.

Planning:

Planning:

In planning the portions of the audit which may be affected by the client’s CIS environment, the auditor should obtain an understanding of the significance and complexity of the CIS activities and the availability of data for use in the audit.

This understanding would include such matters as: The significance and complexity of computer processing in each significant

accounting application. The organizational structure of the client’s CIS activities and the extent of

concentration or distribution of computer processing throughout the entity. The availability of data.

Planning:An application may be considered to be complex when: The volume of transactions is such that users would find it difficult to identify

and correct errors in processing. The computer automatically generates material transactions or entries

directly to another application. The computer performs complicated computations of financial information

and/or automatically generates material transactions or entries that cannot be (or are not) validated independently.

Transactions are exchanged electronically with other organizations (as in electronic data interchange (EDI) systems) without manual review for propriety or reasonableness.

When the CIS are significant, the auditor should also obtain an understanding of the CIS environment and whether it may influence the assessment of inherent and control risks.

Planning:

The nature of the risks and the internal control characteristics in CIS environments include the following: Lack of transaction trails

Uniform processing of transactions

Lack of segregation of functions

Potential for errors and irregularities

Initiation or execution of transactions

Dependence of other controls over computer processing

Potential for increased management supervision

Potential for the use of computer-assisted audit techniques.

In accordance with ISA 400, “Risk Assessments and Internal Control,” the auditor should make an assessment of inherent and control risks for material financial statement assertions.

Assessment of Risk:

The inherent risks and control risks in a CIS environment may have both a pervasive effect and an account-specific effect on the likelihood of material misstatements, as follows: The risks may result from deficiencies in pervasive CIS activities The risks may increase the potential for errors or fraudulent activities in

specific applications, in specific databases or master files, or in specific processing activities.

In accordance with ISA 400, “Risk Assessments and Internal Control,” the auditor should consider the CIS environment in designing audit procedures to reduce audit risk to an acceptably low level.

Audit Procedures:

To obtain sufficient evidential matter, the auditor can use either: manual audit procedures, computer-assisted audit techniques, or a combination of both

Obtains sufficient appropriate audit evidence in accordance with PSA 620 “Using the Work of an Expert”;

Considers how the work is integrated with work of others on the audit, & what procedures are undertaken regarding risks identified through the expert’s work.

PAPS 1013

KNOWLEDGE OF THE BUSINESS

PSA 310, “Knowledge of the Business” requires that the auditor obtain a knowledge of the business sufficient to enable the auditor to identify and understand the events, transactions and practices that may have a significant effect on the financial statements or on the audit report.

Includes knowledge of economy and industry

fundamental to assessing the significance of e-commerce to the entity’s business activities and any effect on audit risk

PAPS 1013

KNOWLEDGE OF THE BUSINESS

In obtaining or updating knowledge of the entity’s business, the auditor considers, so far as they affect the financial statements:

Entity’s business activities and industry

Entity’s e-com strategy

Extent of entity’s e-com activities

Entity’s outsourcing arrangements

PAPS 1013

KNOWLEDGE OF THE BUSINESS

Matters that may be relevant to the auditor when considering the entity’s e-commerce strategy in the context of the auditor’s understanding of the control environment, include: involvement of those charged with governance in considering the

alignment of e-commerce activities with the entity’s overall business strategy,

whether e-commerce supports a new activity for the entity, or whether it is intended to make existing activities more efficient or reach new markets for existing activities,

sources of revenue for the entity and how these are changing (for example, whether the entity will be acting as a principal or agent for goods or services sold),

PAPS 1013

KNOWLEDGE OF THE BUSINESS

management’s evaluation of how e-commerce affects the earnings of the entity and its financial requirements,

management’s attitude to risk and how this may affect the risk profile of the entity,

the extent to which management has identified e-commerce opportunities and risks in a documented strategy that is supported by appropriate controls, or whether e-commerce is subject to ad hoc development responding to opportunities and risks as they arise, and

management’s commitment to relevant codes of best practice or web seal programs.

PAPS 1013

KNOWLEDGE OF BUSINESS

The extent of e-commerce use affects the nature of risks to be addressed by the entity

* As an entity becomes more involved with e-commerce, and as its internal systems become more integrated and complex, it becomes more likely that new ways of transacting business will differ from traditional forms of business activity and will introduce new types of risks.

PAPS 1013

KNOWLEDGE OF THE BUSINESS

Internet Service Providers (ISPs), Application Service Providers (ASPs) and data hosting companies may provide many or all of the IT requirements of e-commerce as well as order fulfillment, delivery of goods, operation of call centers and certain accounting functions.

PSA 402, “Audit Considerations Relating to Entities Using Service Organizations” provides guidance on assessing the effect that the service entity has on control risk.

PAPS 1013

RISK IDENTIFICATION

Business risks to e-com activities:

1. Loss of transaction integrity

- lack of an adequate audit trail in either paper or electronic form2. Pervasive e-commerce security risks

- virus attacks and fraud by customers, employees and others through unauthorized access or identity misrepresentation3. System availability risks

- risk that the entity’s infrastructure is not capable of meeting disclosed system availability requirements, security practices, and applicable laws and regulations

PAPS 1013

RISK IDENTIFICATION

4. Loss of information privacy

leading to loss in customer confidence

personal information collected by websites not adequately protected or is misused

5. Improper accounting policies

6. noncompliance with taxation and other legal and regulatory requirements

particularly when Internet e-commerce transactions are conducted across international boundaries

PAPS 1013

RISK IDENTIFICATION

7. failure to ensure that contracts evidenced only by electronic means are binding

8. Over reliance on e-commerce when placing significant business systems or other business transactions on the Internet

PAPS 1013

RISK IDENTIFICATION

Appropriate security infrastructure and related controls, which generally include measures to:

1. verify the identity of customers and suppliers,

2. ensure the integrity of transactions and business processes,

3. ensure that information and information systems are available during the period disclosed by the entity,

PAPS 1013

RISK IDENTIFICATION

4. obtain agreement on terms of trade, including agreement of delivery and credit terms and dispute resolution processes, which may address tracking of transactions and procedures to ensure a party to a transaction cannot later deny having agreed to specified terms (nonrepudiation procedures),

5. obtain payment from, or secure credit facilities for, customers, and

6. establish privacy and information protection protocols.

PAPS 1013

RISK IDENTIFICATION

A comprehensive international legal framework for e-commerce and an efficient infrastructure to support such a framework does not yet exist.

Legal or regulatory issues that may be particularly relevant in an e-commerce environment include:

1. adherence to national and international privacy requirements,

2. adherence to national and international requirements for regulated industries,

3. the enforceability of contracts,

PAPS 1013

RISK IDENTIFICATION

4. the legality of particular activities, for example Internet gambling,

5. the risk of money laundering, and

6. violation of intellectual property rights.

PAPS 1013

RISK IDENTIFICATION

PSA 250, “Consideration of Laws and Regulations in an Audit of Financial Statements” requires that when planning and performing audit procedures and in evaluating and reporting the results thereof, the auditor recognize that noncompliance by the entity with laws and regulations may materially affect the financial statements. PSA 250 also requires that, in order to plan the audit, the auditor should obtain a general understanding of the legal and regulatory framework applicable to the entity and the industry and how the entity is complying with that framework.

PAPS 1013

INTERNAL CONTROL CONSIDERATIONS

In accordance with PSA 400, “Risk Assessments and Internal Control,” the auditor considers the control environment and control procedures the entity has applied to its e-commerce activities to the extent they are relevant to the financial statement assertions

PAPS 1013

INTERNAL CONTROL CONSIDERATIONS

The auditor considers such matters as:

1. the effective use of firewalls and virus protection software,

2. the effective use of encryption, including both:

maintaining the privacy and security of transmissions

preventing the misuse of encryption technology

3. controls over the development and implementation of systems used to support e-commerce activities,

PAPS 1013

INTERNAL CONTROL CONSIDERATIONS

4. whether security controls in place continue to be effective, and

5. whether the control environment supports the control procedures implemented

Auditor considers completeness, accuracy, timeliness and authorization of information provided for recording and processing in the entity’s financial records (transaction integrity).

PAPS 1013

INTERNAL CONTROL CONSIDERATIONS

audit procedures for sophisticated e-commerce often focus on automated controls that relate to the integrity of transactions as they are captured and then immediately and automatically processed

PAPS 1013

INTERNAL CONTROL CONSIDERATIONS

In an e-commerce environment, controls relating to transaction integrity are often designed to, for example:

validate input,

prevent duplication or omission of transactions,

ensure the terms of trade have been agreed before an order is processed, including delivery and credit terms, which may require, for example, that payment is obtained when an order is placed,

PAPS 1013

INTERNAL CONTROL CONSIDERATIONS

distinguish between customer browsing and orders placed, ensure a party to a transaction cannot later deny having agreed to specified terms (non-repudiation), and ensure transactions are with approved parties when appropriate,

prevent incomplete processing by ensuring all steps are completed and recorded (for example, for a business to consumer transaction: order accepted, payment received, goods/services delivered and accounting system updated) or if all steps are not completed and recorded, by rejecting the order,

ensure the proper distribution of transaction details across multiple systems in a network (for example, when data is collected centrally and is communicated to various resource managers to execute the transaction), and

ensure records are properly retained, backed-up and secured.

PAPS 1013

INTERNAL CONTROL CONSIDERATION

Process alignment refers to the way various IT systems are integrated with one another and thus operate, in effect, as one system

The way e-commerce transactions are captured and transferred to the entity’s accounting system may affect such matters as:

1. the completeness and accuracy of transaction processing and information storage,

2. the timing of the recognition of sales revenues, purchases and other transactions, and

3. identification and recording of disputed transactions.

PAPS 1013

EFFECT OF ELECTRONIC RECORDS ON AUDIT EVIDENCE

The auditor considers whether the entity’s security of information policies, and security controls as implemented, are adequate to prevent unauthorized changes to the accounting system or records, or to systems that provide data to the accounting system.

PAPS 1013

The auditor may test automated controls, such as record integrity checks, electronic date stamps, digital signatures, and version controls when considering the integrity of electronic evidence. Depending on the auditor’s assessment of these controls, the auditor may also consider the need to perform additional procedures such as confirming transaction details or account balances with third parties (refer to PSA 505, “External Confirmations”).
