The Better Way of Applying Benford’s Law for Fraud Detection

Applying Benford’s Law on large collections of data is an effective way of detecting fraud. In this article, we?ll introduce you to Benford’s Law, talk about how auditors are employing it in fraud detection, and introduce you to a more effective way of integrating it into an IT solution.

Benford’s Law in a nutshell

Benford’s Law states that certain data sets – including certain accounting numbers – exhibit a non-uniform distribution of first digits. Simply put, if you gather all the first digits (e.g. 8 is the first digit of ?814 and 1 is the first digit of ?1768) of all the numbers that make up one of these data sets, the smallest digits will appear more frequently than the larger ones.

That is, according to Benford’s Law,

1 should comprise roughly 30.1% of all first digits;
2 should be 17.6%;
3 should be 12.5%;
4 should be 9.7%, and so on.

Notice that the 1s (ones) occur far more frequently than the rest. Those who are not familiar with Benford’s Law tend to assume that all digits should be distributed uniformly. So when fraudulent individuals tinker with accounting data, they may end up putting in more 9s or 8s than there actually should be.

Once an accounting data set is found to show a large deviation from this distribution, then auditors move in to make a closer inspection.

Benford’s Law spreadsheets and templates

Because Benford’s Law has been proven to be effective in discovering unnaturally-behaving data sets (such as those manipulated by fraudsters), many auditors have created simple software solutions that apply this law. Most of these solutions, owing to the fact that a large majority of accounting departments use spreadsheets, come in the form of spreadsheet templates.

You can easily find free downloadable spreadsheet templates that apply Benford’s Law as well as simple How-To articles that can help you to implement the law on your own existing spreadsheets. Just Google “Benford’s law template” or “Benford’s law spreadsheet”.

I suggest you try out some of them yourself to get a feel on how they work.

The problem with Benford’s Law when used on spreadsheets

There’s actually another reason why I wanted you to try those spreadsheet templates and How-To’s yourself. I wanted you to see how susceptible these solutions are to trivial errors. Whenever you work on these spreadsheet templates – or your own spreadsheets for that matter – when implementing Benford’s Law, you can commit mistakes when copy-pasting values, specifying ranges, entering formulas, and so on.

Furthermore, some of the data might be located in different spreadsheets, which can likewise by found in different departments and have to be emailed for consolidation. The departments who own this data will have to extract the needed data from their own spreadsheets, transfer them to another spreadsheet, and send them to the person in-charge of consolidation.

These activities can introduce errors as well. That’s why we think that, while Benford’s Law can be an effective tool for detecting fraud, spreadsheet-based working environments can taint the entire fraud detection process.

There?s actually a better IT solution where you can use Benford’s Law.

Why a server-based solution works better

In order to apply Benford’s Law more effectively, you need to use it in an environment that implements better controls than what spreadsheets can offer. What we propose is a server-based system.

In a server-based system, your data is placed in a secure database. People who want to input data or access existing data will have to go through access controls such as login procedures. These systems also have features that log access history so that you can trace who accessed which and when.

If Benford’s Law is integrated into such a system, there would be no need for any error-prone copy-pasting activities because all the data is stored in one place. Thus, fraud detection initiatives can be much faster and more reliable.

Operational Reviews

IT OPERATIONAL REVIEWS DEFINED
An IT operational review is an in-depth and objective review of an entire organisation or a specific segment of that organisation. It can be used to identify and address existing concerns within your company such as communication issues between departments, problems with customer relations, operating procedures, lack of profitability issues, and other factors that affect the stability of the business.
Operational reviews allow the organisation members to evaluate how well they are performing, given that they perform appropriately according to the procedures set by them, allocating their resources properly, and performing such tasks within time frame set and using cost-effective measures. More importantly, it also shows your company how well it is prepared to meet future challenges.
Simply put, the goals of an operational review are to increase revenue, improve market share, and reduce cost.

THE BENEFITS OF AN IT OPERATIONAL REVIEW
The main objective of IT operational reviews is to help organisations like yours learn how to deal with and address issues, instead of simply reacting to the challenges brought about by growth and change.
In such review, the information provided is practical from both a financial and operational perspective. Using these data, the management can then come up with recommendations, which are not only realistic, but more importantly, can help the organisation achieve its goals. The review recognises the extent to which your internal controls actually work, and enables you to identify and understand your strengths, weaknesses, opportunities and threats

To be more specific, let’s list down the ways wherein an effective operational review can contribute to the success of the organisation.

The review process can:
– assess compliance within your own organisational objectives, policies and procedures;
– evaluate specific company operations independently and objectively;
– give an impartial assessment regarding the effectiveness of an organisation’s control systems;
– identify the appropriate standards for quantifying achievement of organisational objectives;
– evaluate the reliability and value of the company?s management data and reports;
– pinpoint problem areas and their underlying causes;
– give rise to opportunities that may increase profit, augment revenue, and reduce costs without sacrificing the quality of the product or service.
Thus, each operational review conducted is unique, and can be holistic or specific to the activities of one department.

Implementing Matrix Management

Matrix management is a culture change. More than the hierarchical structures, lines of responsibilities, modes of communication and channels of decision-making, it is a concept that needs to be planned ahead and managed appropriately over time.

Implementing matrix management to any organization can be confusing. It is essential to ensure that it fits right to your business strategies, skills and competencies. With this, realizing matrix management should not be taken lightly. Careful stages should be considered, instead.

Here are the steps to proper implementation of matrix management:

Consider Your Business Context

You need to evaluate your organisation to analyse what are your development needs with regards to skills, products, services and market environment. This will help you decide on what type of matrix structure you will apply in your organisation. Consider the following questions in building up your context:

  • What is our strategy?
  • Where are the demands in our business?
  • What are the structures that our competitors currently employ?
  • What are the talents that my people possess?
  • What are other business organizations doing?

Set Your Implementation Scope

Next, you need to define the parameter and set the scope of your implementation. What area in your business do you think matrix management will successfully work? There are several things that you need to consider in setting your scope. You have to make sure that it works well with your overall business strategies, that it can be excellently communicated and easily understood. Also, you must ensure that you acquire the necessary talents and skills in the business to deliver the new system of responsibilities.

Implement the New Structure

When you have already decided what structure type you will implement, you are ready to give it a go. You will need to establish new communication channels so you can monitor the progress and receive feedback effectively.

Here?s how to apply the matrix structure:

  • Highlight your development needs
  • Define roles based on outputs and not inputs
  • Line up procedures and systems to support the structure and the behaviour that comes with it.
  • Invest in training and development
  • Support the key people in the structure by coaching them to better adapt in changes
  • Communicate regularly
  • Monitor progress and make necessary adjustments

Review the Matrix Structure, Roles and Responsibilities

Organisations that successfully implement matrix management adapt to the changes in their environment. With this, they do regular evaluations to highlight the need for changes and revisions. The review can either focus on the structure only or to the entire process as a whole. The results can alter the structure, the roles involved and the responsibilities taken.

The process of implementing matrix management follows a step-by step method. Each stage is equally important with the rest. Hence, if you plan to exploit it in your organisation, you have to recognise the purpose of each step and follow it appropriately. Balance is the key. And when you achieve stability in matrix management, amidst the complex changes in the world of business, then your organisational success is just around the corner.

Computer Forensics

So you had a customer data security breach last weekend? Do you know you could be held liable in court for failing to implement required security procedures? That’s right. Due to the overwhelming surge in identity theft wherein nearly 20 million Americans have already been affected, most states have enacted laws to curtail this fast rising crime. Therefore, it is important to redefine how your company deals with customer data security.

  • First, you’ll want to know what your obligations are as dictated by law. Some places, for example, require the destruction or deletion of personal data through shredding, erasing, or by rendering them undecipherable.
  • Second, not only do you need to comply with the said requirements, you’ll also have to prove in court that you actually complied if ever a security breach does happen.
  • Third, you need to be aware of your post-breach duties to avoid being dealt additional penalties.

Obviously, such situations now call for individuals who are experts in both the legal and technical aspects regarding data security. Such individuals are practitioners of a relatively new discipline known as computer forensics.

Armed with our computer forensics specialists, we’ll be able to help you deal with the above concerns. As a result, you can be prevented from having to pay fines that can go up to hundreds of thousands of euros.

There are other equally important reasons why you would want to avail of computer forensics services. For example, you’ll need computer forensics specialists because you want to:

  • Catch a person involved in criminal activities such as child porn, stealing of personal data, and destroying intellectual property.
  • Investigate a computer, network, or even a mobile device for clues that may lead to the culprit.
  • Determine the extent and possible causes when you discover your digital data has been damaged.
  • Find and recover damaged, deleted or encrypted data regardless of whether the cause was intentional or not. If the data in question will be used as evidence in a legal action, there are certain procedures that need to be followed during recovery operations to retain the integrity of the data. Computer forensic specialists are highly qualified for such operations.
  • Implement security policies in your organisation. Such policies have to operate within legal bounds if you want to avoid possible sanctions in the future. These policies should also be designed such that future forensic operations can be conducted with a high likelihood of success.

That said, a company that integrates computer forensics into its IT security policies and practices will be better equipped to remedy the situation once data security has already been compromised than a company that doesn’t.
