'The Internet issue'

Earlier this year I wrote a retrospective on Y2K and said that I'd be back to talk about what is surely the biggest cluster of information risks facing the world over two decades on, namely those associated with the Internet.   Well OK, so it has taken me a couple of months to get around to it but anyway here goes. Threats Malicious individuals Malicious groups Accidents and natural events Vulnerabilities Shared resource Insecure base Naivete  Impacts Extreme dependence Cascading effects Catastrophic outages Preventive controls Detective controls Corrective controls Technical controls Procedural controls Administrative controls  

Audit/review questions

Image
Other than the classic "Show me", here are a bunch of generic questions to consider, select and refine if you are conducting an ISMS internal audit, IT audit, ISMS management review etc. looking into 'X' (an ISMS, situation, system, process, control, incident or whatever). Hopefully these are thought-provoking, helping you consider and explore X from different perspectives.  Are there any legal, regulatory or contractual compliance implications of X? Are there any other things about X that I/management should know about? Can I do some audit tests on X, please? Compared to Y and Z, how risky/valuable/reliable is X? Does anything strike you as strange or worrying about X? Explain the controls relating to X … Has X ever hurt anyone? What happened? Have you or anyone else raised concerns about X? How big is X - how wide, how heavy, how numerous, how often? How come previous efforts did not fix X? How costly was X?

ISO27k ISMS metrics

Information is clearly a valuable yet fragile corporate asset that must be protected against a wide range of threats. Protecting information is complicated by its ubiquity, plus its intangible and ephemeral, dynamic nature, on top of which the information risks are also constantly changing. Furthermore, information risks have to be managed alongside all other risks facing the business, of which there are many. Information risk management is a tough challenge, made still harder if management lacks sufficient, relevant and reliable information concerning the status of information risk management activities, processes, information security etc .   "What  should  we be measuring?" is a common refrain, along with "What are the most common security metrics?". At face value, these are perfectly reasonable and sensible questions. However the first is impossible to answer without knowing more about the organization's situation, while the second is trickier still: scie...

Yet another interpretation of 'cyber'

Image
I have railed repeatedly at the vague and often inappropriate or misleading use of 'cyber', in particular cyber-risk and cybersecurity (inconsistently hyphenated, as shown). Usually, cyber simply means IT - all the usual humdrum risks and controls relating to IT systems and networks. This is everyday stuff, nothing special. Plain IT covers it. Sometimes cyber  alludes to far more extreme and sinster threats associated with highly competent and resourceful adversaries sponsored by governments, organised criminals or terrorists attacking critical national or global infrastructures - the sorts of things that might be experienced during war. Those using the term in this way tend to speak in riddles, trying hard to avoid admitting or disclosing vulnerabilities while denying knowledge of any involvement in such activities. 

Awareness risks & opportunities

 Security awareness program can be planned and prioritised on the basis of risks Leave room (flexibility) to respond to opportunities that arise off-plan

Tempering professional paranoia

It goes with the territory: professionals working in information risk and related areas are, of course, highly aware of risks within our specialism. It's what we do.  Furthermore, many of us would admit to being naturally risk-averse: people outside the profession seem to take chances that we would prefer to avoid or shy away from, whether through plain ignorance or failure to appreciate the risks.   Risk-aversion is a personal characteristic or bias that varies from mild caution and pessimism up to extreme, debilitating paranoia. It doesn't necessarily mean that we are timid, scared or weak, rather that we tend to place more emphasis on the possibility of problems or incidents compared to non-risk-averse people.    

Riding the waves

Image
  Yesterday, I wrote about preparing and promoting your budget proposal, strategy, programme of projects or an individual initiative, gaining management support and negotiating for approval. Today I'd like to emphasis a fleeting, easily overlooked step in your journey, an opportunity to do even better. At the very moment when the negotiations are completed and management finally agrees your infosec budget, their interest, motivation and support for it is high ... so, before the dust settles, why not seize the moment: a window of opportunity has opened. Before long, the wave of enthusiasm will subside and management's focus will turn to other matters. 

Budgeting and preparing for ISO27k

Image
  Are you responsible for your organisation's information risk and security or cybersecurity budget? Are you busily putting the finishing touches to your FY 2023 budget request? Budgeting is a stressful management task, figuring out the figures and anticipating tough battles ahead leading (usually) to a disappointing outcome and yet more problems resulting from inadequate investment. With  clear signs of another global recession looming (as if COVID, climate change and the war in Ukraine weren't challenging enough already), tightened belt-buckles are the order of the day*.

COVID information risk analysis - retrospective

Image
Two and a half years ago in March 2020 as we were fast approaching our first lockdown, I published the following P robability I mpact G raph depicting my analysis of the information risks relating to COVID: The PIG reports the information risks I identified at the time, thinking about COVID from the general societal perspective as opposed to a personal or organisational perspective.

On a mission

Image
  We're on a mission to convince every organisation that managing information risks properly is more than just a compliance imperative.  It's good for business. Is your organisation looking to raise its security game? Are managers worried about ransomware, privacy breaches and intellectual property theft, especially now with so many of us working from home?  What about the business continuity risks with supply chains stressed to breaking point by COVID, recession and war? Are your suppliers cutting corners on privacy and security, hoping nobody will notice? Are desperate competitors taking advantage of the disruption to undermine your cyber-defences? Worse still, is management blissfully unaware of the issues, with everyone heads-down, rowing hard, too busy to notice the icebergs dead ahead? ... Or is there a strong drive to secure  and  exploit information as an integral part of operations? Does being trusted by customers and stakeholders equate to brand value,...

ISO/IEC 27001:2022 pros and cons

Image
I can think of eight key advantages and opportunities in adopting the new third edition of ISO/IEC 27001 as opposed to the second edition nearly a decade old:

Information risks a-gurgling

Image
There are clearly substantial information risks associated with the redaction of sensitive elements from disclosed reports and other formats, risks that the controls don't necessarily fully mitigate. Yes, controls are fallible and constrained, leaving residual risks. This is hardly Earth-shattering news to any competent professional or enlightened infidel, and yet others are frequently shocked.  A new report* from a research team at the University of Illinois specifically concerns failures in the redaction processes and tools applied to  PDF documents . The physical size of redacted text denoted (covered or replaced) with a variable-length black rectangle may give clues as to the original content, while historically a disappointing number of redaction attempts have failed to prevent the original information being recovered simply by removing the cover images or selecting then pasting the underlying text. Doh!

ISO27k is ...

... a cluster of international standards on information security management and related topics ... derived from British Standard BS 7799, itself based on an information   security  manual generously donated to the UK government's Department of Trade and Industry by the fuel company Shell International ... the product of  ISO/IEC Joint Technical Committee 1 SubCommittee 27

Exciting news: extension ladders, stubby snakes!

Image
Having done, seen and learnt a lot in the course of working with the ISO27k standards and precursors since the mid-90's, I'm keen to share my accumulated knowledge with those of you who are relatively new to the field, just setting out and perhaps struggling to get to grips with it all. You needn't learn everything the hard way like I did: I can help you move ahead smartly, avoiding tar pits, finding taller ladders and shorter snakes.

SHOUTY vs ambient infosec

Like ambient music (muzak, elevator tunes), ambient information security blends into the background.  The idea is that infosec controls are subtle, seamless, integral parts of whatever is going on, as opposed to blatant in-yer-face shouty SECURITY. Of course it's not always possible, and there are circumstances where the visibility of security is itself a valuable part of the controls - deterrents, for example, warning signs, distinct boundaries and the menacing presence of beefy security guards, with guns, dogs and attitude.   Personal identification and authentication processes that require user interaction are hard to miss e.g. security passes/tokens, passwords, PIN codes, SMS codes and all that rigmarole. Nevertheless, there are choices for system/security architects when designing login mechanisms that affect the amount of time and effort required from each user.   Those are the exceptions. A majority of security controls go largely unnoticed. Federate...

Governance gardening

Prompted by a random podcast comment and inspired by a productive day in the garden, here's an analogy between governance and gardening. 

Governance is ...

Fractal ISMS changes

Image
'6.3 Planning of changes' is a succinct new clause in ISO/IEC 27001:2022, one accidentally omitted from the contents listing (oops). Simply put, changes to the Information Security Management System must be planned, rather than simply happening haphazardly. What kinds of ISMS changes would this cover? Without further clarification, it could be argued that any and every change to the ISMS has to be "carried out in a planned manner", begging further questions about the intended purpose and scope of the clause, and of the ISMS itself.  If we add a new topic-specific information security policy on IoT, for instance, or update the risks list, would such changes need to be planned? How about simply renaming the organisation's list of risks to, say, Information Risk Register - should that be planned? Would correcting a little typo in an ISMS procedure or awareness item count as an ISMS change that has to be planned?

7 security culture strengtheners

Image
Given research indicating that security culture trumps security policies , how can we strengthen the corporate security culture? Here are a few ideas to set you thinking:

Putting policies under pressure

Image
A note on LinkeDin led me to an intriguing scientific research study that tested the following five hypotheses: People who receive instructions via a written policy about rules will have better knowledge of these rules than those that do not.  People who receive a shorter form version of policy about the rules with less text will have better knowledge of the rules than those who receive a longer training form.  People who receive a written policy outlining the rules in a more vernacular and less legal technical language will have better knowledge of the rules than those presented with a more formal-legal-styled training text.  People with better knowledge of rules will also comply more with such rules. The more legal rules align with people’s personal and social norms, the higher people score in their knowledge of these legal rules.

"any circumstance or event with the potential to adversely impact organizational operations (including mission, functions, image, or reputation), organizational assets, individuals, other organizations, or the Nation through an information system via unauthorized access, destruction, disclosure, modification of information, and/or denial of service"  [source:  NIST SP800-30r1 ] ... "a person, situation or event (whether deliberate or accidental, targeted or generic in nature) that is hazardous or dangerous, capable of causing an  information   security  incident" [source:  SecAware glossary ] ...

Since October is cybersecurity awareness month in the USA, we've seized the opportunity to update SecAware.com with additional information on our security awareness material.  SecAware's information security awareness modules explore a deliberately wide variety of individual topics in some depth:

Under starters orders

  Like an expectant father, I've been anxiously filling-in time before the publication of ISO/IEC 27001 :2022, due any day now. Today, I completed the tedious process of reviewing/updating all our information security policy templates for SecAware.com . 

ISO/IEC 27001:2013 --> 2022 transition

Image
SEE UPDATE 19th Feb 2023 The third edition of ISO/IEC 27001 will have a few changes in the main body text and a complete replacement for Annex A based on  ISO/IEC 27002:2022 .     The transition arrangements are still uncertain but this is my understanding at this point:
