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.

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.

Maturing Into CMMI

 

In all likelihood, the reason why you landed on this page was because you were seeking CMMI experts to help you meet the demands of a growing number of potential clients who require CMMI compliance.

Whether or not you’re here for that reason, you might want to know why CMMI or Capability Maturity Model Integration is steadily becoming a common denominator among highly successful software and engineering development companies. If you stay for a while, we can show you how CMMI can substantially increase your organisation’s chances of:

  • reducing development costs;
  • acquiring new customers and retaining old ones;
  • beating deadlines;
  • bringing down development time;
  • increasing the overall quality of your products and services; and
  • improving the level of satisfaction of customers, employees, and all other stakeholders.

Surely, no organisation can be too small or too big to aspire for such benefits of attaining high levels of maturity and capability.

If you want to look beyond Maturity Level ratings, then you’ve come to the right place. We focus on introducing CMMI principles and blending them into your organisation’s culture to achieve a truly superior and sustainable business advantage. Compliance will then be an inevitable offshoot of the actions you make.

Likewise, if you simply want to obtain a deeper understanding of CMMI and learn how it can be applied either to your entire organisation or to specific projects, we’d be happy to assist you in that regard as well.

Finally, when you’re ready, we can also conduct CMMI appraisals either for benchmarking purposes or simply for determining how well your process improvement initiatives are going.

CMMI Consulting

Are you worried that implementing CMMI might entail an overhaul of your current processes? Don’t be.

CMMI is all about improving current processes, not replacing them. Ideally, the final result of all process improvement activities should be hinged on your own business objectives and context, so we’ll make sure it remains that way when we work with you.

We rely on our extensive knowledge and experience in CMMI, engineering, software development, and technologies as well as in change and project management in providing model-based process improvement services. Whether you’re gearing up for an appraisal or simply want to employ CMMI-based practices, these are the things we can do for you.

  • Help you interpret how CMMI can be implemented in relation to your business.
  • Assist in convincing sponsors and stakeholders to support your CMMI implementation initiatives.
  • Introduce the necessary training to all individuals who need to undertake them.
  • Conduct a Gap Analysis to find out where your company’s current processes stand relative to their CMMI specifications.
  • Assemble a process group that will champion your process improvement initiatives. We’ll facilitate effective collaboration among its team members, transforming them into a cohesive force designed to carry out plans and motivate everyone else down the line.
  • Introduce tools and practices that will improve the efficiency of our process improvement initiatives.
  • Carry out periodic evaluations and produce reports to provide sponsors and stakeholders a clear picture of our progress.

CMMI Training

Still not convinced CMMI is right for you? There’s only one way to fully grasp the benefits of implementing CMMI – take the Introduction to CMMI course. Although what happens next is entirely up to you, we’re pretty sure you’ll make the right decision after passing it.

Do you need to include people from your organisation in a SCAMPI (Standard CMMI Appraisal Method for Process Improvement) team? They’ll have to undergo this course too. The Introduction to CMMI is for systems and software engineering managers and practitioners, appraisal team members, process group members, and basically anyone who want to grasp CMMI fundamentals.

This is what you’ll be able to do after going through 3 days of lectures and exercises:

  • Gain a deeper understanding of the various components of CMMI-DEV models and their relationships.
  • Discuss the process areas in CMMI-DEV models.
  • Extract and interpret aspects in the model relevant to your own organisation’s processes.

We also offer highly specialised training and workshops such as those for:

  • Achieving High Maturity Levels
  • Top Executives
  • Team Building in Preparation for Appraisals

CMMI Appraisal

An organisation new to CMMI will want to know first how far their current processes are relative to the implementation of model-based improvements in order to determine the resources and time that have to be spent to get there.

Similarly, an organisation already well acquainted with CMMI and has begun taking steps in improving processes, will eventually want to know how close it has come to the Maturity Level it has aimed for.

In both cases, these organisations will have to be assessed by a qualified CMMI appraiser to obtain an accurate picture of their current status. We can perform appraisals on either your entire organisation or on specific projects/practices within a process area. Our appraisers can conduct the following SCAMPI (Standard CMMI Appraisal Method for Process Improvement) appraisals:

  • SCAMPI Class A – This is what you’ll need if you’re aiming for a level rating.
  • SCAMPI Class B – You may want to use this for process reviews or for preparing for a SCAMPI Class A.
  • SCAMPI Class C or Gap Analysis – We typically conduct this for organisations who have yet to implement CMMI-based initiatives so that they can design the most cost-effective road map for the implementation proper.
How the Dodd-Frank Act affects Investment Banking

The regulatory reform known as the Dodd-Frank Act has been hailed as the most revolutionary, comprehensive financial policy implemented in the United States since the years of the Great Depression. Created to protect consumers and investors, the Dodd-Frank Act is made up of a set of regulations and restrictions overseen by a number of specific government departments. As a result of this continuous scrutiny, banks and financial institutions are now subject to more-stringent accountability and full-disclosure transparency in all transactions.

The Dodd-Frank Act was also created to keep checks and balances on mega-giant financial firms that were considered too big to crash or default. This was especially deemed crucial after the collapse of the powerhouse financial institution Lehman Brothers in 2008. The intended result is to bring an end to the recent rash of bailouts that have plagued the U.S. financial system.

Additionally, the Dodd-Frank Act was created to protect consumers from unethical, abusive practices in the financial services industry. In recent years, reports of many of these abuses have centered around unethical lending practices and astronomically-high interest rates from mortgage lenders and banks.

Originally created by Representative Barney Frank, Senator Chris Dodd and Senator Dick Durbin, the Dodd-Frank Wall Street Reform and Consumer Protection Act, as it is officially called, originated as a response to the problems and financial abuses that had been exposed during the nation’s economic recession, which began to worsen in 2008. The bill was signed into law and enacted by President Obama on July 21, 2010.

Although it may seem complicated, the Dodd-Frank Act can be more easily comprehended if broken down to its most essential points, especially the points that most affect investment banking. Here are some of the component acts within the Dodd-Frank Act that directly involve regulation for investment banks and lending institutions:

* Financial Stability Oversight Council (FSOC): The FSOC is a committee of nine member departments, including the Securities and Exchange Commission, the Federal Reserve and the Consumer Financial Protection Bureau. With the Treasury Secretary as chairman, the FSOC determines whether or not a bank is getting too big. If it is, the Federal Reserve can request that a bank increase its reserve requirement, which is made up of funds in reserve that aren’t being used for business or lending costs. The FSOC also has contingencies for banks in case they become insolvent in any way.

? The Volcker Rule: The Volcker Rule bans banks from investing, owning or trading any funds for their own profit. This includes sponsoring hedge funds, maintaining private equity funds, and any other sort of similar trading or investing. As an exception, banks will still be allowed to do trading under certain conditions, such as currency trading to circulate and offset their own foreign currency holdings. The primary purpose of the Volcker Rule is to prohibit banks from trading for their own financial gain, rather than trading for the benefit of their clients. The Volcker Rule also serves to prohibit banks from putting their own capital in high-risk investments, particularly since the government is guaranteeing all of their deposits. For the next two years, the government has given banks a grace period to restructure their own funding system so as to comply with this rule.

? Commodity Futures Trading Commission (CFTC): The CFTC regulates derivative trades and requires them to be made in public. Derivative trades, such as credit default swaps, are regularly transacted among financial institutions, but the new regulation insures that all such trades must now be done under full disclosure.

? Consumer Financial Protection Bureau (CFPB): The CFPB was created to protect customers and consumers from unscrupulous, unethical business practices by banks and other financial institutions. One way the CFPB works is by providing a toll-free hotline for consumers with questions about mortgage loans and other credit and lending issues. The 24- hour hotline also allows consumers to report any problems they have with specific financial services and institutions.

? Whistle-Blowing Provision: As part of its plan to eradicate corrupt insider trading practices, the Dodd-Frank Act has a proviso allowing anyone with information about these types of violations to come forward. Consumers can report these irregularities directly to the government, and may be eligible to receive a financial reward for doing so.

Critics of the Dodd-Frank Act feel that these regulations are too harsh, and speculate that the enactment of these restrictions will only serve to send more business to European investment banks. Nevertheless, there is general agreement that the Dodd-Frank Act became necessary because of the unscrupulous behaviour of the financial institutions themselves. Although these irregular and ultimately unethical practices resulted in the downfall of some institutions, others survived or were bailed out at the government’s expense.

Because of these factors, there was more than the usual bi-partisan support for the Dodd-Frank Act. As a means of checks and balances, the hope is that the new regulations will make the world of investment banking a safer place for the consumer.
