Stop for a moment and take a look around you – IT isn’t just the computer on your desk, the laptop in your bag or the mobile in your pocket. The truth is it’s controlling who is and isn’t entering your building, both virtually and physically; determining how and where your customers are being dealt with; driving your production line; and it even has a part to play in how your coffee is produced.

IT is no longer confined to a small back office, possibly in the basement, staffed with geeks all speaking their own language. IT keeps you open for business – but if you’re not careful it can close you down for good.

For every business there is a requirement to exercise both due diligence and care for the company’s assets and the future ability to produce returns for investors from revenues. This is increasingly embedded in legislation, regulation, standards and best practice guidelines. I’m not going to provide a definitive list because it is neither necessary for this article nor realistically possible due to the frequency with which legislation changes, or is amended, and the differences in terminology between sectors and countries.

Suffice to say that in order to exercise due diligence and care you need to plan for the day when you can’t – in other words, have an up-to-date business continuity plan.

I challenge you to get a copy of your plan (if you have one), dust it off and actually read it. In the majority of cases it will cover eventualities such as damage caused by fire, theft or even flooding. If you’re based in a city it may even include a section on external threats i.e. terrorist attacks.

You probably have a plan for overcoming a power failure, where to resource external staff if yours are ill and, if you’re in production, crisis management if your product fails.

What does it say about suffering a cyber attack? Chances are it doesn’t.

Most companies, irrespective of whether they are a single office or a large international conglomerate, are reliant on computer systems to function. If you were attacked tomorrow, the reality is it will shut you down. How long it takes to get back up and running, if at all, is down to you. Sit up, take note and plan for the inevitable.

You’re under attack
An attacker isn’t just interested in stealing information or funds. Organisations are experiencing attacks, whether denial of service or injected with malware, that are designed to wreak havoc and ideally shut the business down. Recent high-profile victims include Wikileaks, Facebook and Twitter. However, it’s often not just the victim that suffers as PayPal, Visa and Mastercard can attest to having fallen victim by association.

Any company can be a target because it’s not just anonymous cyber terrorists waiting to pounce – a disgruntled employee could wreak just as much havoc on your system if the notion takes them. There is also the chance your IT system simply just fails, as happened to the BBC recently.

Being closed for business, however temporarily, will cost the organisation money. For an online retailer this is a little more obvious because there’s the immediate loss of revenue if customers aren’t able to make purchases.

However, if the IT infrastructure of a large manufacturing company fails and production has to shut down for 24 hours the costs will soon mount, potentially into the millions. The expense isn’t limited to the immediate problem of restoring services or production: there’s the lost time, ruined stock, ongoing costs of rebuilding confidence in the customer base and also potentially among shareholders, plus the knock-on effects such as an increase in insurance premiums.

The 2010 AT&T Business Continuity Study reported that:

  • three-quarters (77%) of organisations indicate that employee use of mobile devices plays a major/minor role in the business continuity plan
  • half (50%) have virtualised their computing infrastructure, with less than four out of 10 (38%) having implemented a business continuity plan for the virtualised infrastructure
  • 84% of all companies surveyed have e-mail or text messaging capabilities to reach employees outside of work, and three-fourths (73%) have systems in place that enable most employees to work from home or remote locations.

While, on the surface, all of these resources offer a lifeline to an organisation in the event of a general infrastructure failing, and you’ve probably rubber-stamped the budget on some of these initiatives yourself, on a day-to-day basis they also ‘throw open the doors’ to the outside world, risking extreme disruption through attack.

First line of defence
An organisation’s IT team has many responsibilities but with one main, overriding objective: to deliver the best service possible. However, this does not always promote the best security possible. Why? Well, budgets are usually the biggest issue. CEOs must understand the need for enhanced security and ensure their IT team deliver it.

When the corporation has spent millions on network defences it is then close to incompetence to not make sure those investments are working to the optimum effectiveness. Regular audit and validation leads to enhanced security, which costs very little and is a must-have process.

With constant vulnerability testing and security enhancement through configuration, better rules can be defined and implemented. This activity can even avoid additional capital expenditure in unnecessary security devices, saving budgets.

Making sure your defences are working to the optimum is not just the responsibility of the CIO, CSO or whatever you call your IT management head – it goes all the way to the top. The function of the CEO and board of directors, as part of their legal responsibility and charge by shareholders, is to exercise good corporate governance.

You wouldn’t build your office on the sand, so why allow your IT infrastructure to have insecure foundations. Ignoring your network defences is tantamount to corporate suicide.
