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.

Spreadsheet Risk Issues

It is interesting to note that the riskiness of operational spreadsheets are overlooked even by companies with high standards of risk management. Only when errors amount to actual losses do they realize that these risks have been staring them in the face all along.

Common spreadsheet risk issues

Susceptibility to trivial manual errors

Due to the fundamental structure of spreadsheets, a slight change in the formula or value in any of their inhabited cells may already affect their overall output. An

  • accidental copy-paste,
  • omission of a negative sign,
  • erroneous range selection,
  • incorrect data input or
  • unintentional deletion of a character,cell, range, column, or row

are just some of the simple errors spreadsheet users frequently encounter. Rarely are there any counter-checking controls in place in a spreadsheet-based activity and manual errors therefore easily go undetected.

Possibility of the user working on the wrong version

How do you store spreadsheet files?

Since the most common reports are usually generated on a monthly basis, users tend to store them using variations of these two configurations:

spreadsheet storage

If you notice, a user can accidentally work on the wrong version with any of these structures.

Prone to inconsistent company-wide reporting

This happens when a summary or ?final? spreadsheet is fed information by different departments coming from their own spreadsheets. Even if most of the data in their spreadsheets come from one source (the company-wide database), erroneous copy-pasting and linking, or even different interpretations of the same data can result to contradicting information in the end.

Often defenceless against unauthorised access

Some spreadsheets contain information needed by various individuals or department units in an organisation. Hence, they are often shared via email or through shared folders in a network. Now, because spreadsheets don’t normally use any access control, any user can easily open a spreadsheet file and view or modify the contents as he wishes.

Highly vulnerable to fraud

A complex spreadsheet system with zero or very minimal controls provides the perfect setting for would-be fraudsters. Hidden cells with malicious formulas and links to bogus information can go unnoticed for a long time especially if the final figures don’t deviate much from expected values.

Spreadsheet risk mitigation solutions may not suffice

Inherent complexity makes testing and logic inspection very time consuming

Deep testing can uncover possible errors hidden in spreadsheet cells and consequently mitigate risks. But spreadsheets used to support financial reporting are normally large, complex, highly-personalised and, without ample supporting documentation, understandably hard to follow.

No clear ownership of risk management responsibilities

There?s always a dilemma when an organisation starts assigning risk management responsibilities for spreadsheets. IT personnel believe users in the business side of the organisation should be responsible since they are the ones who create, edit, store, duplicate, and share the spreadsheet files. On the other hand, users believe IT should be responsible since they have always been in-charge of managing IT infrastructure, applications, and files.

To get rid of spreadsheet risks, you’ll have to get rid of spreadsheets altogether

One remedy is to have a risk management activity that involves both IT personnel and spreadsheet users. But wouldn’t you want to get rid of the complexity of having to distribute the responsibilities between the two parties instead of just one?

Are Master Data Management and Hadoop a Good Match?

Master Data is the critical electronic information about the company we cannot afford to lose. Accordingly, we should sanitise it, look after it, and store it safely in several separate places that are independent of each other. The advent of Big Data introduced the current era of huge repositories ?in the clouds?. They are not, of course but at least they are remote. This short article includes a discussion about Hadoop, and whether this is a good platform to back up your Master Data.

About Hadoop

Hadoop is an open-source Apache software framework built on the assumption that hardware failure is so common that backups are unavoidable. It comprises a storage area and a management part that distributes the data to smaller nodes where it processes faster and more efficiently. Prominent users include Yahoo! and Facebook. In fact more than half Fortune 50 companies were using Hadoop in 2013.

Hadoop – initially launched in December 2011 ? has survived its baptism of fire and became a respected, reliable option. But is this something the average business owner can tackle on their own? Bear in mind that open source software generally comes with little implementation support from the vendor.

The Hadoop Strong Suite

  • Free to download, use and contribute to
  • Everything you need ?in the box? to get started
  • Distributed across multiple fire-walled computers
  • Fast processing of data held in efficient cluster nodes
  • Massive scaleable storage you are unlikely to run out of

Practical Constraints

There is more to Hadoop than writing to WordPress. The most straightforward solutions are uploading using Java commands, obtaining an interface mechanism, or using third party vendor connectors such as ACCESS or SAS. The system does not replace the need for IT support, although it is cheap and exceptionally powerful.

The Not-Free Safer Option

Smaller companies without in-depth in-house support are wise to engage with a technical intermediary. There are companies providing commercial implementations followed by support. Microsoft, Amazon and Google among others all have commercial versions in their catalogues, and support teams at the end of the line.

Disaster Recovery

Because information technology is now integrated in most businesses, a business continuity plan (BCP) cannot be complete without a corresponding disaster recovery plan (DRP). While a BCP encompasses everything needed – personnel, facilities, communications, processes and IT infrastructure – for a continuous delivery of products and services, a DRP is more focused on the IT aspects of the plan.

If you’re still not sure how big an impact loss of data can have, it’s time you pondered on the survival statistics of companies that incurred data losses after getting hit by a major disaster: 46% never recovered and 51% eventually folded after only two years.

Realising how damaging data loss can be to their entire business, most large enterprises allocate no less than 2% of their IT budget to disaster recovery planning. Those with more sensitive data apportion twice more than that.

A sound disaster recovery plan is hinged on the principles of business continuity. As such, our DRP (Disaster Recovery Plan) blueprints are aimed at getting your IT system up and running in no time. Here’s what we can do for you:

  • Since the number one turn-off against BCPs and DRPs are their price tags, we’ll make a thorough and realistic assessment of possible risks to determine what specific methods need to be applied to your organisation and make sure you don’t spend more than you should.
  • Provide an option for virtualisation to enjoy substantial savings on disaster recovery costs.
  • Provide various backup options and suggest schedules and practices most suitable for your daily transactions.
  • Offer data replication to help you achieve business continuity with the shortest allowable downtime.
  • Refer to your overall BCP to determine your organisation’s critical functions, services, and products as well as their respective priority rankings to know what corresponding IT processes need to be in place first.
  • Implement IT Security to your system to reduce the risks associated with malware and hackers.
  • Introduce best practices to make future disaster recovery efforts as seamless as possible.
