Having previously considered information risks within the policy scope, writing the policy involved determining how to treat the risks and hence what information security or other controls are most appropriate.
Here we drew on guidance from the ISO27k standards, plus other standards, advisories and good practices that we’ve picked up in the course of ~30 years in the field, working with a variety of industries and organizations – and that’s an interesting part of the challenge of developing generic policy templates. Different organizations – even different business units, departments, offices or teams within a given organization – can take markedly different attitudes towards clear desk and screen. The most paranoid are obsessive about it, mandating controls that would be excessive and inappropriate for most others. Conversely, some are decidedly lax, to the point that information is (to my mind) distinctly and unnecessarily vulnerable to deliberate and accidental threats. We’ve picked out controls that we feel are commonplace, cost-effective and hence sensible for most organizations.
COVID19 raises another concern, namely how the risks and controls in this area vary between home offices or other non-corporate ‘working from home’ workplaces, compared to typical corporate offices and other workplaces. The variety of situations makes it tricky to develop a brief, general policy without delving into all the possibilities and specifics. The approach we’ve taken is to mention this aspect and recommend just a few key controls, hoping that workers will get the point. Customers can always customise the policy templates, for example adding explicit restrictions for particular types of information, relaxing things under certain conditions, or beefing-up the monitoring, oversight and compliance controls that accompany the policies – which is yet another complicating factor: the business context for information security policies goes beyond the written words into how they are used and mandated in practice.
Doing all of this in a way that condenses the topic to just a few pages of good practice guidance, well-written in a motivational yet generic manner, and forms a valuable part of the SecAware policy suite, explains the hours we’ve sunk into the research and writing. Let’s hope it’s a best seller!
