ISMS implementation project guidance checklist




This checklist will be appended to a new SecAware guideline on implementing an ISMS, elaborating clause-by-clause on ISO/IEC 27001 - essentially, our version of ISO/IEC 27003.  It offers pragmatic guidance for information security managers and CISOs - nothing too obscure or complex.

---oooOOOooo---

Project definition, justification, scoping and planning

⬚  Study the standards, in depth: complete lead implementer training if possible.

  Study the business, in depth, to understand its objectives, strategies, culture, governance arrangements, existing information risk and security management etc.

  If the organisation has a defined, structured approach for this phase, use it!

  Build a business case that identifies and promotes the business benefits of the ISMS.

  Look beyond ‘security’ and ‘compliance’ e.g. helping management to manage business risks, supporting/enabling other business initiatives and strategies.

  Identify, explore and elaborate on a broad set of business objectives relating to: information risk and security management; information, cyber, manual and automated security controls; compliance and assurance; resilience; good practice, maturity; efficiency, cost-effectiveness etc.

  Clarify relative priorities for the objectives e.g. by ranking them all or grouping them into categories such as ‘essential’, ‘important’, ‘nice-to-have’ and perhaps ‘to be avoided’.

  Be honest about the organisational/governance changes ahead, including the potential disruption, costs and timescales.

  Be realistic about resourcing, priorities and capabilities.

Build-in more than enough slack/contingency to allow for unforeseen difficulties.

  Offer a do-nothing straw man plus other options as appropriate e.g. distinguish essential from important from optional objectives, compare costs and benefits of differing ISMS scopes.


Project approval

  Don’t expect the business case to sell itself, no matter how exciting and positive it seems.

  Hawk it around management, informing them, gathering feedback and amending the proposal.

  Identify, explore and address genuine concerns, especially blockers.

  Look for opportunities to align with corporate strategies and other initiatives.

  Refine the objectives and project proposal, adding explicit details where clarity is needed or helps e.g. metrics.

  While awaiting approval, continue working on the planning and ideally progressing the essential aspects such as information risk assessment.

  Be crystal clear about those essentials and only compromise in other areas, even if that means the project is refused or deferred.


Implementation activities

  Aim low, strike high: focus intensely on those essentials, progressing other objectives at lower priority/urgency if resources allow.

  Where possible, re-use existing content, policies, procedures, controls etc., adapting as necessary.

  Collaborate closely with related teams/functions/organisations/individuals.

  Work to up-skill the core team through training, mentoring and experience on the job.

  Start operating elements of the ISMS as soon as practicable, practising and refining them and ideally accounting for the benefits gained (financial or otherwise).

  Look for early wins and promote them: positive feedback is invaluable for motivation and energy.


Project management, oversight, progress reporting and project risk management

  If the organisation has a project management method/approach, use it!

  Work with experienced programme and project managers.

  Establish suitable governance arrangements (e.g. structure, reporting, metrics, approvals) for the project as that will evolve into the ISMS governance in due course.

  Play snakes-and-ladders: identify and address risks/issues/setbacks, seizing and promoting opportunities to advance.

  Watch the critical path and anything that does or might consume your contingencies, like a hawk.

  Beware stress and burnout: don’t exceed reasonable workloads for long periods, including yours.

  Work hard on clear communications and effective relationships: these will outlast the implementation phase.


Certification and other assurance activities

  Treat certification as an opportunity to improve, more than a hurdle to clear.

  Take time to clarify objectives, identify suppliers and contract with certification bodies.

  Specify experienced and competent certification auditors, anticipating less aggravation and more value-add.

  Line up certification prerequisites such as completed ISMS documentation, records of activities, ISMS internal audits etc.

  Line up management to see the purpose and value of assurance regarding the ISMS, information risk and security management, compliance etc.

  Line up marketing to promote the certification, enhancing corporate brands, opening new business opportunities etc.

  Liaise between the team, management and the certification body closely in the run-up to certification, maintaining alignment and expectations.

  Look beyond the award itself: there is always more to be done, more planning required e.g. integrating other management systems.


Transition to business-as-usual

  Plan for a gradual, sequential/piecemeal ISMS build-and-implementation, rather than a big bang.

  Start using those policies, procedures, metrics, reports etc. as soon as they are available: it inevitably takes time to discover and smooth-off the rough edges, and integrate them all into a coherent, self-sustaining management system, so they constitute ‘improvement opportunities’.

  Keep up the communications within and without the team, squeezing more value from metrics through motivational feedback, direction and reprioritisation.

  Become ever more business- and externally-focused as the ISMS settles into a routine, without neglecting the team and individual needs.

That's it so far ... but your comments and especially improvement suggestions are very welcome. What aspects have I neglected or misrepresented? What would you add or change, based on your experience?
