The SME security problem reflects a deeper fundamental flaw

Over the past six months I’ve been looking at the security requirements of small and medium enterprises. I’ve had some fascinating conversations with numerous security experts, many of whom have varying theories on how the problem should been tackled.

Some believe that the answer lies in adapting the security standards used by bigger companies. The standards community seems to be keen on this approach. They think the answer might be to rewrite existing standards in simpler English. That would be an improvement. But it won’t solve the problem. Even cut down versions of the ISO 27000 standards are inappropriate, containing too many irrelevant requirements for small and micro companies, who don’t have policy portfolios, committees and internal audit functions.

Other practitioners view SMEs as an immature version of a bigger company. They think the answer lies in some form of maturity framework. The problem with this idea is that not all SMEs aspire to grow into a big company. Many are quite content earning a living as a small, profitable enterprise. Pointing out the benefits of achieving a higher level of maturity won’t cut any ice.   

Most security managers in big companies have concluded that, left to their own devices, SMEs are a hopeless cause. They must therefore be compelled by the threat of losing business or being sued for a breach of contract. These security managers regard SMEs as a major security liability, rather than a useful, cost-saving business opportunity. That’s a serious drag on business, which needs to exploit the benefits of smarter, cheaper niche services in order to stay competitive.

Whatever your view, one thing is crystal clear to me, which is that our traditional approaches to selecting countermeasures are flawed. If they only work for large organisations, then they are not fit for purpose for any organisation. Large enterprises themselves are formed of numerous small business units and functions. If security solutions don’t work for small units, they’re not effective for big enterprises.

It’s instructive to take a step back and examine how we go about determining security controls, and why we do it that way. In the early days of information security, controls were implemented only by a small set of enthusiastic computer managers with direct experience of specific risks. They relied on a careful eye and a large degree of imagination. The problem with such a free form approach, however, was that it produced inconsistent results. The next generation of security managers aspired to identify risk assessment methods that might enable an inexperienced practitioner to select an optimal set of countermeasures. Unfortunately, this approach was also flawed because we simply don’t have the psychic ability to predict risks, which have an annoying habit of constantly changing.

One answer to this dilemma was to agree a common set of baseline controls based on established best practice, which prompted a wave of international standards designed by large organisations to address an internal controls requirement. Unfortunately these standards were not designed with sufficient attention to the needs of SMEs or the massive growth in external services. They also fail to address emerging risks.

In practice, security countermeasures are only implemented if there is a clear and present danger (as demonstrated by a major incident), a mandatory requirement (legal or compliance) or if it forms part of a wider system specification. Talk of security as a business enabler is fine for impressing the board but the reality is that such claims rarely translate into a concrete, long term business case.

SMEs, contractors and small business units aim to spend the minimum possible amount on security. It is a grudge purpose. That means that we need to emphasise the highest priorities and communicate the most compelling business drivers, not swamp them with hundreds of good practices to choose from.    

We therefore need to go back to square one and design a more suitable portfolio of solutions, for a broader set of organisations and circumstances. Over the last three decades, the security problem space has grown progressively richer, dynamic and complex, while the recommended solution space has largely stood still. It’s time for a rethink of the fundamentals of information security.

Hi David You make some good points in this article and it's good to see somebody trying to debunk a few myths in IT Security. Your focus in this article is on practical security standards for SME's, but I think your arguments also hold true for security solutions, which can be both practical and inexpensive for SME's to implement if they apply Pareto's law. There are powerful, practical and hugely beneficial IT security and compliance solutions available, either as software or as services that are really inexpensive. The benefits they give in hardening systems against the most frequent security problems and providing audit trails for possible future investigations when aligned with the greater control that SME's typically exercise over their businesses and their staff, can actually raise the security posture of SME's beyond that of large coporates!

One of the key problems with SME's is the system integrators that support them. At best they actually do some attempt at needs analysys, at worst they are simply box shifters. What the SME usually end us with is a cookbook solution rooted in security solutions of the 1990's more often than not unsuited to their needs. The system integrators get their training from the vendors who interest lies in getting them to shift as much of their product as possible. Thus the SME stands little chance of up-to-date, forward looking and fit for purpose.

I think the main issue is the lack of understading by the owners OF SMEs that something needs to be done, and that carries a cost. I agree with the comment re: system integrators. How would someone know they received quality work, be that in security or development? When IT Security is viewed with the same importance as financials, then things will start falling into place.

David, You make some excellent points and I share your concern. We identified 2 years ago that the SME was not considered when the likes of ISO 27001 was published. What’s more, as you rightly point out, little has changed to address this. In an effort to assist large organisations de-risk their use of SMEs (a common place activity), we developed the Certified Digital Security 'standard'. This has a much lower bar for attainment over its 9 levels. The concept being that SMEs can reduce their risks in an incremental and very low cost way. We have guides and links to useful products (3rd party), on our website for visitors to download. We even provide template documents, policies and registers. Check it out at www.certifieddigitalsecurity.com for a breakdown on the each level's requirements look at www.certifieddigitalsecurity.com/roadmap With regard to the SME supporting system integrators, I believe they don't see enough work to actually get involved, and with IT Security being seen as a high cost item, many SMEs don’t even ask the price, never mind get the proposed improvements implemented. I think only by demystifying information security can it gather wider adoption, otherwise it represents the scary question the business owner daren't ask. Steve A
