What is an Audit System? Overview & 10+ Facts

An audit system is a process used to assess the security of your website. In this post, we will look at what exactly an audit system is, how it can benefit your business and what tools you will need to run an effective audit system

What is an Audit System?

Typically, an audit system is a computer software intended to facilitate the execution of audit processes. Accounting companies, auditors, and internal auditing divisions acquire this sort of software.

The fundamental objective of an audit system is to gather data, conduct a random data sample for each audit method, monitor activities, and aid in the preparation of the final report. There are several audit systems available, ranging from modest systems meant for medium-sized businesses to huge enterprise systems used by international corporations.

What is an Audit System?

Importance of system audit

A system audit is essential because it allows a business to assess the performance of its operational systems.

Businesses that do a system audit can:

  1. Evaluate the actual performance of their operations in comparison to what was anticipated.
  2. Confirm that the organization’s goals remain relevant.
  3. Validate whether or not the organization is reaching these goals.
  4. Ensure the reliability of the employed systems.
  5. Examine system logs to confirm systems are operating per requirements.
  6. Identify vulnerabilities and risks
  7. Permit a business to design a mitigation strategy to more effectively attain its goals.
  8. Continually assess the organization’s operational processes to ensure they are in line with its goals.

Scope of a system audit

Depending on the goals, the scope of a system audit might be defined as the typical accomplishment of anticipated outcomes.

For instance, if the audit scope is to examine the right computation of a system, the audit goal will be to determine whether the calculations yield the typical and anticipated outcomes.

There will be an audit finding for any departure from the norm.

An audit that focuses on data privacy and data protection is another example.

This audit’s scope should include how the company’s systems handle access control, database administration, system confidentiality, encryption, etc.

The standard accomplishment of the aim is the safety and security of personal data.

Audit findings will come from any deviations from what is typically anticipated.

Types of system audit

In order to better comprehend the system audit, let’s examine the types of audits that may be conducted.

The following types of system audits are available:

  1. Adequacy audit
  2. Compliance audit
  3. Internal audit
  4. External audit
  5. Extrinsic audit
  6. Process audit

An adequacy audit to evaluate a system and assess whether it meets the system requirements and specifications.

compliance audit is to evaluate how a system is implemented within an organization to comply with certain standards.

The standards can be statutory, regulatory or industry standards, for instance.

An internal audit is carried out by the internal stakeholders within an organization to validate whether or not its systems are properly functioning, effective and achieving their objective.

An internal audit can be performed for any objective important for an organization based on its needs and realities.

This type of audit is referred to as a first-party audit.

An external audit is when the audit is carried out by an outside and independent organization.

The external audit is also called the second-party audit.

An extrinsic audit is when the audit is carried out by an accredited third party.

The extrinsic audit is also called the third-party audit.

process audit is an audit of company processes as a whole in light of the objectives pursued.

System audit process

A system audit process can be in the following phases:

  1. Audit initiation
  2. Audit preparation
  3. Audit execution
  4. Audit report
  5. Audit closure and follow-up

Let’s look at each of the system audit process phases.

Audit initiation

Audit initiation is the beginning of the system auditing procedure.

During audit start, the auditor and client will decide the audit’s scope and frequency.

Priority is given to the client’s demands, goals, objectives, and timetable while determining the project’s scope.

A customer may request an audit of a certain department’s procedures in order to obtain the desired outcome.

The frequency of the audit might be influenced by both the client’s demands and any applicable regulatory obligations.

If a corporation is obliged to conduct a systems audit annually, that requirement must be satisfied annually.

Depending on the client’s demands, audits might be conducted at more frequent intervals.

What is an Audit System?

Audit preparation

When the auditor begins reviewing the system’s auditing protocol, audit preparation is in progress.

In the preparation phase, the objective is to establish an audit strategy that generally include the following:

  1. The audit’s scope
  2. Personnel engaged in the auditing procedure
  3. System standards
  4. Audit planning procedures
  5. Duration of the auditing method
  6. Meeting schedules
  7. Date envisioned for completion

Audit execution

The audit execution is the process of conducting the system audit.

During the audit execution process, the auditor will examine the particulars of the company’s systems, how they function, determine what is compliant and what may not be compliant, seek clarification from the client, etc.

The scope of the audit should include the whole of the agreement.

The identification of any nonconformity must be impartial and objective.

Audit report

The issuing of the audit report marks the conclusion of the system auditing procedure.

The auditor is responsible for producing a report that provides an unbiased assessment of the audited system.

The report must be factual and provide objective proof for any disparities discovered.

In addition, the auditor will assess the company’s compliance with the system standards against which the audit was performed.

Audit closure and follow-up

ISO 19011 defines the conclusion of an audit as:

“The audit is concluded after all scheduled audit operations have been executed, unless otherwise agreed with the audit client.”

We have reached the conclusion of the auditing procedure after all auditing tasks have been completed.

How to conduct a system audit

System audits are often conducted by IT specialists that are acquainted with many information systems and can comprehend how they are interconnected.

Organizations must audit their system’s hardware, software, data, materials, and applications to perform a system audit.

An audit of a system is undertaken as follows:

  1. System review
  2. Vulnerability assessment
  3. Threat identification
  4. Internal controls
  5. Testing

System review

A systems review is the initial stage.

In this stage, the objective is to comprehend the IT architecture, the multiple levels, the management practices, and system integration.

Vulnerability assessment

Next, each application used by the firm must be examined to determine which are the most susceptible.

A corporation cannot completely remove all of its weaknesses.

What is an Audit System?

However, if the organization methodically identifies the susceptible systems and implements the proper controls, it may guarantee that it continues to adhere to the intended requirements.

Threat identification

Defining potential dangers to the organization is the subsequent phase.

Companies are vulnerable to external actors such as hackers, cybercriminals, and external dangers.

In addition to vendors, suppliers, and service providers, external players may also include competitors.

They also face internal dangers from internal users, programmers, system analysts, etc.

Internal controls

In reviewing internal controls, a corporation assesses the adequacy of its internal controls relative to industry standards or potential risks.

If the internal controls do not function as planned, the organization will have to adopt the appropriate checks and balances to guarantee that its goals are met.


The last stage is to test and analyze the management system’s different components to verify they satisfy their goals and adhere to the standards.

Various tests may be conducted to detect systems that do not function as planned or generate the desired outcomes.

System audit report

The system audit report accurately reflects the auditor’s evaluation of the company’s systems and whether or not they function as intended in light of the established criteria or goals.

Audit fieldwork

Audit fieldwork is the procedure through which the auditor determines the anticipated processes, systems, and technologies based on the control activities specified.

The role of an auditor is to evaluate the standards or audit goals and determine the systems and procedures adopted by the organization to achieve the desired outcomes.

Compensating controls

In certain instances, auditors will identify the particular procedures or technology required to meet the control target.

In certain instances, they are unable to discover what they want.

In such a case, a business may direct the auditor to other controls or systems that accomplish the same effect.

This consists of compensatory controls.

A compensating control is a new system or procedure discovered by the auditor to make up for the lack of the controls they were initially seeking.

Audit findings

The auditor will give a “finding” if he or she is unable to identify a compensating control or cannot locate evidence to establish the presence of the control.

A recorded finding describes the control goal that was examined by the auditor.

What is an Audit System?

When an audit finding is made, the auditor will explain why he or she feels the situation hinders management’s ability to fulfill the control goals, what the likely underlying cause is, what the risk is, and what must be done.

When providing a conclusion, auditors must remain objective.

Auditor’s report

At the conclusion of the audit, the auditor will provide a report assessing the audit.

The audit report is the auditor’s overall evaluation of a company’s management system and conformity with established standards or goals.

Typically, the auditor will discuss the audit goals and the process utilized to generate the report.

In addition, the auditor will detail any potential findings he or she has uncovered, as well as any potential suggestions for how the company can address the finding.


Typically, after receiving the systems audit report, a corporation should consider correcting any deviations or inconsistencies identified by the auditor.

It is essential to prepare a remediation plan and execute it in order to eradicate the fundamental cause of the issue that prompted a “finding.”

What are the system audit objectives

System audits are performed for several reasons.

Listed below are many purposes pursued by organizations:

  1. To guarantee that a company’s systems conform to system standards
  2. To determine whether the company’s systems adhere to the system standards.
  3. The evaluation of the efficacy of the company’s systems in achieving its goals.
  4. Allow for system enhancement chances
  5. Conform to legal and regulatory standards

Useful terminology

In the context of an audit process, there are some terms and terminology worth reviewing.

Here is a brief description of terms you may come across:

  • Effectiveness
  • Findings
  • Noncompliance
  • Noncomfornace

The effectiveness of a system relates to how effectively it functions in light of objective facts and predetermined criteria.

A “finding” is a problem uncovered by auditors during a system audit that requires corrections or fixes.

When there seems to be evidence that the systems deviate considerably from the standards or that the system is not working, a finding might be deemed crucial.

A finding can be minor as well.

When there is an issue that has to be addressed, or when there is room for improvement.

Noncompliance occurs when there is objective proof that a corporation is not complying with a mandated legislation, rule, or norm.

Nonconformance occurs when there is proof that a process or system does not comply with the requirements or supporting documentation.

Use Cases

Watching file access: Audit may monitor if a file or directory has been accessed, edited, executed, or its properties altered. This is handy for detecting access to key files and keeping an Audit trail in case one of these files becomes corrupted.

Monitoring system calls: Audit may be set to create a log entry whenever a certain system call is executed. This may be used, for instance, to monitor the settimeofday, clock adjtime, and other time-related system functions to observe changes to the system time.

What is an Audit System?

Recording commands run by a user: Due to the fact that Audit can monitor if a file has been run, a number of criteria may be set to log each execution of a certain command. For each executable in the /bin directory, for instance, a rule may be specified. The resultant log entries may then be searched by user ID to provide an audit trail of instructions performed by each user.

Recording security events: The pam faillock authentication module may report unsuccessful login attempts. Audit may also be configured to record unsuccessful login attempts and offers more details about the user who tried to get in.

Searching for events: Audit contains the ausearch tool, which may be used to filter log entries and generate a comprehensive audit trail depending on a variety of circumstances.

Running summary reports: The aureport utility may, among other things, be used to create daily reports on recorded occurrences. After analyzing these data, a system administrator may examine questionable activities further.

Monitoring network access: System administrators may monitor network access by configuring the iptables and ebtables programs to generate Audit events.

Objectives of the System Audit

The presence of technology in an increasing number of corporate domains necessitates a system of management, monitoring, and analysis, such as system auditing. In the first place, it is essential to ensure data security, as well as their privacy and appropriate usage. Second, the computer system enables quick mistake detection and decision-making, making the process far more productive and lucrative.

Consequently, we may argue that the audit’s goals are:

  • Increase the cost-effectiveness of information systems
  • Enhance the contentment and safety of the consumers of these computerized systems.
  • Ensure confidentiality and integrity with the aid of expert security and control systems
  • Minimize the presence of potential threats, such as viruses or hackers, for instance.
  • Improve and simplify decision making
  • As this is a rapidly evolving and relatively young industry, it is vital to educate users of these computerized processes on the management of information systems.

Systems auditing is thus a way for monitoring and evaluating more than just the computer hardware itself. Its remit also include the management of the entry systems to this equipment (think, for example, access codes and codes), archives and their security, etc.

What is an audit management system?

An audit management system is a piece of software that considerably reduces the time and effort required to pass an external audit or perform an internal audit. It simplifies the process by automating audit lifecycle operations.Integration of audit software with a document management system enables users to locate and retrieve audit program material.

Audit management software helps organizations fulfill board-approved audit directions. It also facilitates the streamlining and organization of audit compilation processes and cooperation.

Continuous auditing is necessitated by the need of effective risk management and compliance with government and industry norms. For firms governed by the National Institute of Standards and Technology Cybersecurity Framework or ISO 27001 or the Payment Card Industry Data Security Standard, frequent compliance audits lower the risk of noncompliance.

A complete audit management system enables businesses to handle audit planning, audit-related activities, audit data, and audit procedures. In addition, it enables businesses to establish and manage audit checklists, identify potential improvement areas, and execute the procedures required to take remedial steps.

Other sophisticated system features allow firms to follow industry best practices to achieve successful audits. These capabilities include remedial processes, email notifications and alerts, risk assessment methods, and offline auditing capabilities.

With audit software, businesses may monitor prior audit results, keep a record of audit reports, and anticipate preventative steps in the spirit of continuous development.

Frequently asked questions

In this section, we will look at a few questions frequently asked about system audits.

What are the three types of audits?

Generally, there are three types of audits:

  1. Process audit
  2. Product audit
  3. System audit

The objective of a process audit is to examine and audit the processes to verify that they are functioning as planned.

A product audit is the examination of a particular product or service against its specified specifications or performance criteria.

A system audit is an examination of a management system to determine whether or not its components are effective and correctly executed in order to satisfy the goals or criteria.

What is a system-based audit?

A system-based audit, according to the Oxford Reference, is:

“An approach to auditing based on the premise that an auditor may establish an opinion on the quality of an organization’s internal control system by studying and evaluating it, hence determining the extent to which substantive tests must be performed”

What is an Audit System?

This is a kind of audit where the auditor uses the organization’s internal control system to identify the necessary tests and verifications.

Unlike a risk-based audit, a system-based audit assesses internal control mechanisms based on risk criteria.

What is the difference between a system audit and process audit?

A system is a cohesive unification of activities, techniques, equipment, systems, data, or measurements.

Generally speaking, a system audit is a verification of the conformance of a management system.

It is the audit of how the systems interrelate and interact to accomplish specified and well stated goals.

In contrast, a process is a succession of actions that result in a transformation.

Through the application of procedures, businesses may accomplish a result or effect a change.

A process audit enables a corporation to detect inefficiencies and accomplish improvements beyond the restricted control features outlined by a specific standard.

While a system audit investigates the rules and then checks the interrelationship of the systems against those rules, a process audit examines the process to verify whether the final product conforms to the rules.

A system audit may disclose compliance or nonconformity, but a process audit can identify inefficiencies and places for development.

What is a process audit?

A process audit is a verification of a company’s procedures used to accomplish a desired outcome.

The objective of a process audit is to discover inefficiencies, while the objective of a system audit is to find nonconformance.

For instance, a system may create the appropriate output when given a certain output.

That is system auditing.

The purpose of a process audit is to examine a company’s operations, activities, resources, people and system behavior, and the use of technology and systems in order to get a desired outcome.

The process audit will examine the organizational process to evaluate whether it is managed effectively and if its activities are arranged in the most effective manner to reach the desired outcome.


An audit system is simply a way to check whether or not your current systems are functioning properly and are keeping you on track with your business goals.

In other words, you’ll be able to measure how successful you’re becoming, and whether or not your strategy is working.

Once you’ve figured out what your current processes and systems are doing, you’ll be able to implement new changes to make sure you get the results you need.

This can include things like implementing better methods for tracking your customers and how they are using your website, or perhaps creating a better email marketing program.
