2021-10-15 12:40:00 | Topic-specific policy 4/11: information transfer (lien direct) |  "Information transfer" is another ambiguous, potentially misleading title for a policy, even if it includes "information security". Depending on the context and the reader's understanding, it might mean or imply a security policy concerning:Any passage of information between any two or more end points - network datacommunications, for instance, sending someone a letter, speaking to them or drawing them a picture, body language, discussing business or personal matters, voyeurism, surveillance and spying etc.One way flows or a mutual, bilateral or multilateral exchange of information.Formal business reporting between the organisation and some third party, such as the external auditors, stockholders, banks or authorities.Discrete batch-mode data transfers (e.g. sending backup or archival tapes to a safe store, or updating secret keys in distributed hardware security modules), routine/regular/frequent transfers (e.g. strings of network packets), sporadic/exceptional/one-off transfers (e.g. subject access requests for personal information) or whatever. Transmission of information through broadcasting, training and awareness activities, reporting, policies, documentation, seminars, publications, blogs etc., plus its reception and comprehension. Internal communications within the organisation, for example between different business units, departments, teams and/or individuals, or between layers in the management hierarchy."Official"/mandatory, formalised disclosures to authorities or other third parties.Informal/unintended or formal/intentional communications that reveal or disclose sensitive information (raising confidentiality concerns) or critical information (with integrity and availability aspects). Formal provision of valuable information, for instance when a client discusses a case with a lawyer, accountant, auditor or some other professional. Legal transfer of information ownership, copyright etc. between parties, for example when a company takes over another or licenses its intellectual property.Again there are contextual ramifications. The nature and importance of information transfers differ between, say, hospitals and health service providers, consultants and their clients, social media companies and their customers, and battalion HQ with operating units out in the field. There is a common factor, however, namely information risk. The in |

2021-10-14 17:20:00 | Topic-specific policy 3/11: asset management (lien direct) |  This piece is different to the others in this blog series. I'm seizing the opportunity to explain the thinking behind, and the steps involved in researching and drafting, an information security policy through a worked example. This is about the policy development process, more than the asset management policy per se. One reason is that, despite having written numerous policies on other topics in the same general area, we hadn't appreciated the value of an asset management policy, as such, even allowing for the ambiguous title of the example given in the current draft of ISO/IEC 27002:2022. The standard formally but (in my opinion) misleadingly defines asset as 'anything that has value to the organization', with an unhelpful note distinguishing primary from supporting assets. By literal substitution, 'anything that has value to the organization management' is the third example information security policy topic in section 5.1 ... but what does that actually mean?Hmmmm. Isn't it tautologous? Does anything not of value even require management? Is the final word in 'anything that has value to the organization management' a noun or verb i.e. does the policy concern the management of organizational assets, or is it about securing organizational assets that are valuable to its managers; or both, or something else entirely? Well, OK then, perhaps the standard is suggesting a policy on the information security aspects involved in managing information assets, by which I mean both the intangible information content and (as applicable) the physical storage media and processing/communications systems such as hard drives and computer networks?Seeking inspiration, Googling 'information security asset management policy' found me a policy by Sefton Council along those lines: with about 4 full pages of content, it covers security aspects of both the information content and IT systems, more specifically information ownership, valuation and acceptable use:1.2. Policy Statement The purpose of this policy is to achieve and maintain appropriate protection of organisational assets. It does this by ensuring that every information asset has an owner and that the nature and value of each asset is fully understood. It also ensures that the boundaries of acceptable use are clearly defined for anyone that has access to |
