By Tom Edwards & Yasmin Wilks
If you’re an auditor, you’ve probably achieved your fair share of success stories – perhaps you’ve witnessed a few failures too.
As the saying goes, we learn from our mistakes, and audit case studies, both failures and successes serve as valuable insight. Real-life audit examples provide us with lessons on what to do and what to avoid, enabling organisations to improve their audit processes.
Ready to discover some real-world examples? Here’s our pick of a few high-profile cases…
When things go wrong
(1) enron corporation.
The Enron scandal and the subsequent collapse of the Enron Corporation serves as a stark reminder of audit failure and corporate misconduct. Possibly the most high-profile scandal ever unearthed, the Sarbanes-Oxley Act (SOX) of 2002 was passed as a result of scandals such as this, WorldCom, Tyco, and Global Crossing.
Enron's auditor Arthur Andersen was heavily criticised for failing to detect fraudulent financial reporting. And lots of lessons can be learned from this example.
Firstly, Enron’s case highlights the importance of auditors maintaining independence from the companies they audit to ensure unbiased assessments. But it also reminds us of the importance of whistle-blower protection – where there are safeguards in place, organisations will encourage openness and provide the confidence for individuals discovering financial irregularities to expose them. And Enron finally emphasises how crucial regulatory oversight is in holding auditors accountable and preventing corporate fraud.
(2) Toshiba
We’ve all heard of Toshiba , a renowned multinational conglomerate, manufacturing a wide variety of consumer and business products. Despite the company’s famous success, this chapter of their story is not one of their finest.
In July 2015, Toshiba experienced an internal audit failure that spotlighted the gap between good corporate governance structure and its practical implementation. It led to Toshiba Corp’s president, Hisao Tanaka, and his two predecessors quitting after investigators found that the company had inflated earnings by $1.2 billion between 2009 and 2014.
Regardless of a sound governance structure, the organisation suffered from a massive financial scandal, highlighting the importance of proactive internal auditing to identify and prevent financial irregularities.
(3) Ernst & Young
Even the largest professional services companies are sometimes at the centre of an audit scandal. And in the case of Ernst & Young , these kinds of scenarios serve as a reminder of the importance of a robust auditing process for even the biggest of players.
EY was fined $11.8 million for audit failures in 2016. USA regulator SEC found that EY’s audit team repeatedly failed to detect fraudulent activity for more than four consecutive years. Additionally, it was reported that EY’s team failed to take effective measures in minimising known recurring tax-related problems.
This case emphasises the critical role auditors play in scrutinising high-risk areas and addressing known deficiencies. And underscores the importance of due diligence and thoroughness in audits.
(4) WorldCom
The WorldCom scandal is another example of a colossal audit failure. Arthur Andersen, the same auditor implicated in the Enron scandal, failed to detect a massive accounting fraud at WorldCom.
What can we learn from this tale? Well, attentive auditing is essential, and auditors need to exercise a blend of vigilance and scepticism when assessing financial statements. This example also points to ethical responsibility, underscoring auditors’ moral and ethical duty to report financial irregularities.
Like Enron, WorldCom’s case was instrumental in regulatory reforms, like the Sarbanes-Oxley Act which increased corporate accountability.
Getting it right
(1) apple inc.
Tech giant Apple is widely recognised for its financial transparency and internal controls. Their financial audits consistently reflect strong performance and accountability. Key takeaways from Apple's success include their transparency – Apple publishes detailed financial statements and reports that are easily accessible to the public, building trust with investors and stakeholders. They also have a set of robust internal controls and processes in place, minimising the risk of financial mismanagement or fraud.
The organisation’s MD Tim Cook says , “We do the right thing, even when it’s not easy.”
(2) Microsoft
Microsoft's another great example of a business with transparency and accountability at its core. The tech leader has consistently demonstrated exemplary corporate governance and financial reporting .
Their success highlights several valuable lessons, including the significance of disclosure. Microsoft provides comprehensive financial disclosures, offering investors a clear picture of their financial health. And they’ve also got their finger on the pulse when it comes to risk management , with practices in place that have been instrumental in ensuring long-term financial stability.
Microsoft carries out consistent and regular financial audits , to maintain trust and transparency with all of their stakeholders.
(3) Johnson & Johnson
Johnson & Johnson's another example of a profound commitment to transparency . The healthcare multinational is renowned for its sense of responsibility when it comes to ethical conduct.
Key takeaways include their strong ethical leadership – an essential asset for fostering a culture of compliance and accountability.
They also boast hardy compliance programs , proving that investing in this area can help detect and prevent financial misconduct. Stakeholder communication is another factor in Johnson & Johnson’s audit success, and open comms are encouraged to build trust and confidence.
What can we learn from all these case studies? The need for thoroughness, vigilance, transparency, ethical leadership, and continual improvement in auditing are essential. They emphasise the importance of not just having a good corporate governance structure, but also ensuring its effective implementation. And by learning from both successes and failures, we can strive to build a corporate environment that prioritises (financial) integrity and compliance with relevant regulatory, legal, and industry standards – and, of course foster trust and prevent costly failures.

Effective IT audit risk management begins with a clear understanding of key concepts. This section will explore the fundamental principles underpinning IT audit risk management and its importance.
IT audit risk management is a comprehensive process that involves identifying, assessing, and mitigating risks associated with an organization’s IT systems. It is crucial for businesses to have a solid understanding of the key concepts in IT audit risk management to effectively protect their sensitive data and ensure the reliability of their IT infrastructure.
One of the key concepts in IT audit risk management is risk appetite. Risk appetite refers to the level of risk an organization is willing to accept to pursue its objectives. It is important for businesses to define their risk appetite as it helps them make informed decisions about the risks they are willing to take and the ones they want to avoid.
Another important concept is risk tolerance. Risk tolerance is the level of risk that an organization is willing to tolerate before taking action to mitigate it. It is closely related to risk appetite but focuses more on the specific thresholds and limits that an organization sets for different types of risks.
In addition to risk appetite and tolerance, organizations must establish a risk appetite framework. A risk appetite framework provides a structured approach to managing risks by defining the organization’s risk appetite, setting risk tolerance levels, and establishing processes for identifying, assessing, and mitigating risks.
The process of IT audit risk management involves identifying and assessing risks, developing risk mitigation strategies, and monitoring and evaluating these strategies. Organizations can effectively manage IT audit risks by understanding key concepts such as risk appetite, risk tolerance, and risk appetite framework.
Identifying and assessing risks is the first step in IT audit risk management. This involves identifying potential risks that could impact the organization’s IT systems, such as cyber threats, system vulnerabilities, and data breaches. Once the risks are identified, they need to be assessed regarding their likelihood and potential impact on the organization.
After assessing the risks, organizations need to develop risk mitigation strategies. These strategies aim to reduce the likelihood and impact of the identified risks. They may include implementing security controls, conducting regular vulnerability assessments, and establishing incident response plans.
Monitoring and evaluating the effectiveness of risk mitigation strategies is an ongoing process in IT audit risk management. It involves regularly reviewing the implemented controls, assessing their effectiveness, and making necessary adjustments to ensure that the organization’s IT systems remain secure and reliable.
IT audit risk management plays a crucial role in ensuring the security and reliability of an organization’s IT systems. By proactively identifying and mitigating risks, businesses can protect sensitive data, maintain operational continuity, and comply with regulatory requirements.

Components of IT Audit Risk Management
IT audit risk management consists of various components that work together to provide a comprehensive risk management strategy. This section explores the three key components: risk identification, assessment, and mitigation.
In this case study, we analyze a real-world scenario where an organization struggled to identify potential IT infrastructure risks. Through careful analysis of their existing systems, documentation, and interviews with key stakeholders, the organization identified and classified various risks, including hardware vulnerabilities, software weaknesses, and outdated security protocols.
Hardware vulnerabilities were identified as a significant risk due to outdated equipment and lack of regular maintenance. The organization discovered that these vulnerabilities could potentially lead to system failures, data breaches, and unauthorized access to sensitive information. The organization could take proactive measures to address and mitigate the potential impact by identifying these risks.
Software weaknesses were another area of concern. The organization found that outdated software versions and lack of patch management exposed them to security vulnerabilities. Malicious actors could exploit these weaknesses to gain unauthorized access, compromise data integrity, and disrupt critical business operations. By recognizing these risks, the organization could prioritize software updates and implement robust security measures to protect their systems.
The organization also identified outdated security protocols as a risk factor. They realized that their existing security measures were no longer sufficient to defend against evolving cyber threats. By acknowledging this risk, the organization could implement stronger authentication methods, enforce stricter access controls, and enhance its security infrastructure to safeguard against potential breaches.
This case study examines how an organization assesses identified risks’ potential impact and likelihood. Utilizing industry-standard risk assessment frameworks, the organization quantified the risks based on their probability and potential impact, enabling them to prioritize mitigation efforts and allocate resources effectively.
The organization thoroughly analyzed each identified risk, considering factors such as the likelihood of occurrence and the potential consequences. They assigned a numerical value to each risk, allowing them to compare and prioritize them based on their severity. This risk assessment process helped the organization understand the most critical risks they faced and guided their decision-making process regarding risk mitigation strategies.
By quantifying the risks, the organization could allocate resources and budget effectively. They focused their efforts on addressing high-risk areas first, ensuring that limited resources were utilized where they would have the most significant impact. This approach allowed the organization to maximize the effectiveness of its risk management efforts and minimize potential losses.
This case study delves into the strategies implemented by an organization to mitigate identified risks. By adopting a multi-layered approach that included network segmentation, encryption protocols, and regular vulnerability assessments, the organization was able to reduce the likelihood and impact of potential security breaches.
The organization recognized that network segmentation was crucial in minimizing the impact of a potential breach. By dividing their network into smaller, isolated segments, they could limit the spread of an attack and prevent unauthorized access to critical systems and data. This approach also allowed them to implement different security measures based on the sensitivity of the information stored in each segment.
Encryption protocols were another key component of the organization’s risk mitigation strategy. By encrypting sensitive data both at rest and in transit, they ensured that even if a breach occurred, the stolen information would be useless to unauthorized individuals. This added layer of protection significantly reduced the potential impact of a successful attack.
Regular vulnerability assessments were also essential in the organization’s risk mitigation efforts. By conducting frequent assessments, they could identify and address any new vulnerabilities that emerged over time. This proactive approach allowed them to stay one step ahead of potential attackers and continuously improve their security posture.
Overall, by implementing a comprehensive risk management strategy that includes risk identification, risk assessment, and risk mitigation, the organization could strengthen its IT infrastructure’s security and reduce the likelihood and impact of potential security breaches. This case study serves as a valuable example of how organizations can effectively manage IT audit risk and protect their valuable assets.
