In the full glare

Here's a neat illustration of the challenges facing those protecting critical national infrastructures.

Take a look at this map of the UK's fuel pipelines - a massive mesh of pipes criss-crossing the country, linking refineries and fuel stores with power stations and airports. Many of the pipes are buried, carrying large volumes of volatile and energetic fuel under substantial pressure for hundreds of miles across open country, along roads, over canals and under cities, hence the need for the map, the website and the organization behind it: trust me, you don't want people accidentally digging them up, or driving piles through them. For health and safety reasons, let alone the risk of serious economic and physical fallout, people driving big yellow mechanical diggers and pile-drivers need to know if they are within striking range of the pipes. Planners, architects and builders need to know where they lie, plus the operators who use and maintain them, oh and the emergency services just in case.

Now imagine you've been tasked with protecting those same pipes against deliberate attacks by, well, anyone with a big yellow digger and a grudge for starters. The list of potential adversaries and their possible reasons is long and changeable. Some of them have serious resources and capabilities behind them, and no particular rush.

The reality of protecting critical infrastructures is rather different than the Popular Mechanics perspective.

Pragmatic ISMS implementation guide (FREE!)

Image
Early this morning ( very  early!) I remotely attended an ISO/IEC JTC 1/SC 27/WG 1 editing meeting in London discussing the planned revision of ISO/IEC 27003:2017 . Overall, the meeting was very productive in that we got through a  long  list of expert comments on the preliminary draft standard, debated the objectives of the project and the standard and reached consensus on most points. In summary: 27003 is to be revised to align with the current 2022 releases of ISO/IEC 27001 , 27002 and 27005 : These changes are  mostly  minor aside from the new section 6.3 on ISMS changes.

Two dozen information risks that ISO forgot

Image
Selecting the wrong controls - controls that are inappropriate, ineffective, too costly, impracticable, fragile, unnecessary, counterproductive or whatever, often as a result of blind faith in fads and fashions of the day and FOMO e.g. MFA, AI, cyber Failing to select the right controls - controls that are ideal for the particular situation, both now and in perpetuity, for whatever reason - mostly ignorance and prejudice Selecting and implementing controls at the wrong time or in the wrong way (where 'wrong' includes ineffective, inappropriate, sub-optimal e.g. bolting on controls rather than designing and building them in) Inept and inaccurate identification, analysis and quantification of risk, including reliance on p oor quality (incomplete, inaccurate, out of date, misleading, unreliable ...) information about actual risks, particularly subtle and emerging risks plus those involving deliberate concealment and misdirection e.g. fraud, misinformation, disinformation, propagan

Philosophical phriday - compliance risk

Image
According to a vendor's promotional video interview I saw recently, the 'cybersecurity compliance burden' has allegedly become so significant that [customer] organisations are eagerly buying [their] software tools and services to help them manage and fulfil their obligations. The vendor's argument goes that, instead of accumulating a ragtag bunch of policies and other controls relating to user Identification and Authentication (I&A), for instance, it makes sense to:  Identify all the cybersecurity-related laws, regulations and standards that apply to the organisation; Examine them for any security control requirements relating to, say, I&A; Rationalise the I&A controls down to the smallest set that satisfies all the requirements - the lowest common denominator; Design, implement, use, manage and maintain those I&A controls; Have the I&A controls checked or audited to gain assurance that the compliance requirements are met.  OK so far? Sounds reasonab

ISMS internal audit priorities

Image
A thread on the ISO27k Forum sparked my imagination over coffee this morning. Hope had previously asked for assistance with an ISO/IEC 27001:2022 audit plan.  Bhushan offered a lengthy and generally sound response explaining how to use a spreadsheet with tabs to plan and record the audit work performed on 100% of the main body clauses and 50% of the 93 Annex A controls, day-by-day. That's OK ... except it wasn't entirely clear that he was interpreting and elaborating on the standard's actual requirements. ISO/IEC 27001 does not explicitly require, for example, that (as Bhushan stated) "ALL the management system clauses from 4 to 10 AND their sub-clauses need to be listed and audited" in an ISMS internal audit, although evidently he interprets it in that way. In clause 9.2.1, the standard states a requirement for internal audits to provide information on whether the ISMS conforms to the organization’s own requirements for the ISMS plus the requirements of the stan

Reading between the lines of ISO27001 [L O N G]

Image
ISO/IEC 27001 is a succinct, formally-worded standard for two key reasons: It is deliberately generic, being applicable to all manner of organisations regardless of difference in location/s, size, industry, maturity, structure, information risk and security status ... and so on. In effect, it specifies the lowest common denominator - the things that ALL organisations should be doing to manage their information security controls, as a minimum. The hurdle is set low enough that every organisation ought to find value in designing, implementing and operating an I nformation S ecurity M anagement S ystem as laid out in the standard. It is a certifiable standard, explicitly specifying the characteristics that every certified organisation's ISMS is expected to have. Again, it is a minimal specification with no concept of typical, average or maximum security: that is entirely down to the organisations themselves to determine, following the information risk management processes minimally de

Passionate dispassion

Image
Someone who is actively involved in, or is managing, an activity is patently not independent of it. They may well make a conscious, rational and determined effort to be objective, dispassionately reviewing evidence etc ., but their subconscious/emotional biases/prejudices and beliefs/value-systems will inevitably influence what they do. With the best will in the world, they will struggle to challenge and assess their past decisions and activities, especially if they were "certain" or "determined" or genuinely believed they were "doing the right thing". Furthermore, it is very hard for anyone to review the things they did not do, decisions they did not make or options they did not even consider. Mostly, they remain out of sight or out of the question.

Philosophical phriday - a noncompliance ramble

Image
In a previous philosophical phriday post , I moaned about vendors of security compliance support/management tools and services over-promising and under-delivering - an admittedly biased, even cynical opinion piece about the compliance imperative . A recent article in Corporate Compliance Insights notes that "CISOs are not just defenders against cyber threats but also champions of compliance and operational resilience". Hmmm, are CISOs 'compliance champs', really? Today, I'm discussing alternatives to being compliance-driven. How else can organisations drive their information risk, security and related concerns in a positive direction?

Adaptive SME security Crowdstrike special

Image
As if on cue, along comes a golden opportunity to consider what the Adaptive SME security  approach has to say regarding the Crowdstrike incident: That's not 20/20 hindsight but foresight: I've picked out the most relevant rows from the security controls table published in the guide 24 hours before the incident.  Although Crowdstrike primarily supplies much larger enterprises than SMEs, the incident could equally have afflicted other security software, or indeed operating systems such as Windows and assorted cloud apps commonly used by SMEs. Regardless of the details, it is a wake-up call, an opportunity to consider and respond to the information risks ... and to adapt , accordingly.
