At a meeting with one of our clients recently, the question of business case for data loss prevention came up quite strongly.

It started with the client saying that they were hearing that while vendors like Symantec and Websense were getting a lot of customers to buy their Data Loass Prevention (DLP) products, many of these customers were failing in their attempt to implement DLP.

The detailed reasons why people fail at DLP implementations merits a separate post – but it’s a lot like why over 50 percent of the content management implementation from vendors like Vignette never made it to production in the 90s – the root cause was that there was no real business case for the technology.

I want to talk about why building a business case for data security is critical to the success of your data security/data loss prevention/fraud prevention project.

If you run a business or business unit – you must ask yourself two questions: Is data security a major operational risk for your business?  Could be!

Unlike a computer virus – internally launched attacks on data that result in data leaks, breach of integrity, loss of data availability and non-compliance are your problem, not someone else’s.

Unlike business processes – data risk cannot be outsourced. Unlike balance sheet assets – companies don’t know their current fnancial exposure to data security threats.

The next question is should you invest in DLP technologies?

Anyone with only a nickel in their pocket (and in this market – that’s a lot of companies…) will say, “Why should we when we don’t know the return on investment?

In order to answer your questions, you must measure your value at risk using a data security based risk assessment.

This is a simple, almost obvious notion – you measure risk of asbestos poisoning by checking your building insulation and you measure risk of fre damage by checking the building itself and various policies, procedures and equipment related to fre prevention.

Think about smoke detectors. You can’t put up an offce building without smoke detectors (in Israel – the regulator has set a minimum density per square meter and the prices are low enough that the contractors will basically put in as many as you want). Why would you think of managing your data without the comparable data breach security monitoring equipment?

Data security based risk assessment uses DLP technology (the test equipment) and a best practices analytical risk model to measure the value of your data and your value at risk. Within a couple weeks, you should be able to get a picture of your current data security events, know your data value at risk in Euro and build a prioritized program for cost-effective data security controls in the people, process and technology planes.

What you do then – is up to you.

Most companies I know in Europe and Israel are not at a suffcient level of security maturity to do this kind of thing themselves and will need an independent consultant  one with specifc domain expertise in their industry vertical, specifc data security expertise and ability to do analytical threat modelling – installing Checkpoint frewalls doesn’t count and you really want someone who is vendor neutral.

Advantages of a data security-focused risk assessment

• Invaluable tool for obtaining visibility of inbound and outbound business transactions.
• Monitoring that provides input into the risk analysis process required by compliance regulation like SOX, PCI DSSand European privacy laws.
• Lays the basis for provable compliance to standards like PCI DSS 1.2 and ISO 27001/2/4.
